Saving energy with these tips

Staying on budget during the summer is not easy. Between all the fun activities for your kids, family vacations, wedding invitations, general expenses, and more, it’s very easy to overspend. The team at Lancaster Brothers Heating and Cooling understands. While we can’t help you save on summer festivities; we can help you save money on your electrical bill and keep your family comfortable. 

1. Don’t Turn Off Your Thermostat (Yes, Really!)

This might seem like a good idea when you are trying to save on costs, but while your air conditioner is off, it allows humidity to build up in your home. When you get back home, your system will have to work extra hard to get that humidity out of the air. If you turn off your thermostat, you’ll just feel uncomfortable and sticky. In some cases, excess humidity and heat can lead to mold growth. Keep your thermostat on and choose a cool, comfortable environment when you arrive home.

2. Do Set the Temperature Up a Few Degrees

Setting the temperature up a few degrees can help you air conditioner to work less, while still keeping your home relatively cool. The U.S. Department of Energy reports that you can save as much as 1% on your utility bills for every degree you bump the temperature up if the setback period is at least eight hours.

Not only will your system use less energy to stay at a higher temperature, but it will also keep the humidity level in your home steady. We recommend setting your thermostat up no more than five degrees.

3. Use a Programmable Thermostat

Everyone is a fan of easy. You can easily control the temperature in your home using a programmable thermostat. The best part? You can set it for whatever temperature you’d like and keep it there while you’re gone. An added advantage is that you can program it to lower the temperature a few hours before you return so you home is cool and comfy when you get back from your big break.

Bonus Tip: Be sure not to put lamps, TV sets, or any other appliances that generate heat near your thermostat.

4. Stop Heat-Producing Activities

Don’t do activities or use items that produce a lot of heat. Things like long hot showers and running your clothing dryer. Also, don’t use the oven. You can always use your microwave or stove to cook, grill outside, or eat a cold meal!

5. Use Your Ceiling Fan for Added Cooling

Use your ceiling fan to your advantage. It doesn’t require a lot of energy to operate, but it can really help circulate cool air throughout a room. 

Bonus Tip: Don’t bother leaving fans on while you’re gone, the windchill effect only helps while you’re in the room. Also, be sure that it’s spinning counter clockwise.

6. Keep Your Blinds Shut During the Day

Don’t forget to close your blinds when you’re away to keep your home from accumulating heat from the sun (solar gain). You don’t want your AC to work any harder than it has to.

7. Open Windows During Cool Summer Nights

On nights when the humidity isn’t too oppressive and the air has cooled off considerably, open some of your windows to allow cool fresh air to circulate throughout your home. Then make sure to close those windows as soon as you get up in the morning to “trap” last night’s cool air inside.

Bonus tip: Don’t open your windows during the day and let all that cool air your air conditioner has been working so hard to pump through your home out.

8. Plant Shade Trees Near Your Windows

Be good to the environment and your thermostat by planting trees. Planting shade trees is another way to keep sun rays from entering your home. We recommend planting shade trees that have mature branches with large leaves next to windows that take direct sunlight during the day. Not only will these trees shade your windows from the sun, but they will also help absorb some of the heat. Your air conditioning unit can also benefit from proper shading, but be sure to keep debris away from your unit.

9. Tune Up Your Air Conditioner

Lastly, always, ALWAYS, make sure you’ve had an air conditioner tune-up before the summer heat is at its peak. Maintenance is the key to keeping your air conditioner efficient, and preventing untimely breakdowns. 

Get Your Special Deal on Lennox Home Comfort Systems

If you think your current air conditioner is on its last leg, we recommend a Lennox Home Comfort System for its high quality and energy efficiency. Call us and we’ll fill you in on the great deals going on with Lennox.

The older your air conditioner gets, the more likely it is to break down. It’s just a fact of life. So if you’re limping along with an older AC hoping it will make it through one more season, the team at Lancaster Brothers has gathered some AC troubleshooting tips just for you.

AC Troubleshooting Tips

The two main problems people encounter with air conditioners are:

  1. It won’t turn on 
  2. It runs, but won’t cool

The following troubleshooting tips can help you beat the heat and get back to enjoying cool air in your home.

Your AC Won’t Turn On

If your AC is not kicking on, you have several things to check:

Thermostat – check your thermostat to make sure that it isn’t set to the heat or off position. Also check to make sure that the batteries in your thermostat are not dead. (You’d be surprised how many service calls we answer and the problem is one of these two things.)

Tripped Breaker – check your electrical panel to make sure that the breaker connected to your AC hasn’t been tripped.

Power Switch – look to see if the power switch on the side of your furnace is turned on. (Yes, there’s a power switch on the side of your furnace.)

The AC Is On, but the Air Isn’t Cool

Dirty Air Filter – One of the biggest issues that will cause this problem is a dirty air filter. Check your filter to see how dirty it is and replace it if necessary. Remember, it is important to change your filter once a month to ensure proper airflow and cooling.

Ice Accumulation – Ice in the outdoor unit can also cause your AC to run sluggishly. If you see ice you should turn off the AC and allow it to thaw for a couple of hours.

Clogged Condensate Drain – If you are still having trouble, consider cleaning out the condensate drain. Algae tends to build up in these pipes and will cause your AC to fail.

Check Your Condenser Unit Outside

Don’t forget your air conditioner has another piece – outside. The condenser unit outside can sometimes be the problem. Look for these three problems:

A safety precaution first – The condenser is a 240-volt box and we don’t want anyone getting hurt, so turn off the power to it at the electrical panel before working on it. Also turn off the disconnect box located outside, near your unit. It will either be a lever, fuses, or a circuit breaker to shut off the condenser. Then, allow about 30 minutes for the electrical charge that’s stored in the condenser’s capacitor to dissipate. Okay, now it’s safe to check the unit. We recommend letting one of our qualified technicians look over these items. 

Clear Debris – Make sure the unit is clean and clear of debris. Clear away dirt, leaves, etc. Check the fan to make sure it is clear of debris as well.

Clogged Drain – Check the drain and make sure it is clear.

Broken Coolant Lines – Check the coolant lines (pipes that connect the condenser unit outside to the evaporator on the inside unit). They can get bumped around being outside.

Turn the unit back on. First, turn the thermostat in your home to OFF. Then turn on the power at both the disconnect box and at the main panel. Last, switch the thermostat to COOL. Give it some time and see if you feel cool air blowing from the ducts. You can also check your outdoor unit to see if the air blowing out the top is warmer than the surrounding air.

A Formula to Know How Many AC Repairs Are Too Many

So you know your AC is on its last leg, but how do you know when it makes the most sense to replace it instead of throwing good money after bad? First, look for these four warning signs:

  • Your unit is 10-12 years old
  • You’ve paid for three or more repairs over the last two years
  • Your energy bills seem excessive
  • You are experiencing uneven cooling or certain rooms feel uncomfortable

NOTE: Sometimes hot spots can be due to poor ductwork. We can inspect your ducts and make adjustments if that is the case.

These are all clues that it is getting close to the time to replace your unit. Luckily, there’s a formula you can use to help you decide. We call it the $5,000 rule.

The $5,000 Rule

Multiply the age of your AC unit by the repair cost, and if that exceeds $5,000, then replace the unit. If it’s less, go ahead and repair it.

Here is an example, if your unit is 10 years old and the repair will cost $350, multiply 10 x 350 to equal $3,500. It is less than $5,000, so it’s okay to have it repaired.

Consider the Rising Cost of Freon

With the rising cost of Freon (coolant used in most older systems), if your repair involves adding Freon because of a leak, you have something else to consider. If you have a Freon leak, you will have to add more every year and the price of Freon is rising each year. The reason is because about 25 years ago, the EPA ordered the phasing out of Freon as part of an international treaty focused on protecting the ozone layer. Production ended in 2010 for new air conditioning units. Production has also been reduced in subsequent years. By 2020, production of Freon will end, so the price will only continue to rise.

Let Lancaster Help with Repairs or Replacement

If your AC has several of the symptoms we listed, we will be happy to take a look and either repair or replace the unit so you and your family stay cool and comfortable. Lancaster Brothers is proud to install Lennox air conditioners, so if your air conditioner is on its last leg we will be happy to provide a free estimate. There are also rebates and financing available for qualifying systems, and our comfort specialist will tell you about all of the available specials.

The last thing you want is for your air conditioner to break down on a hot Kansas City day. Because we know a lot about air conditioners, the Lancaster team put together this list of things to check to give your AC the best chance of running smoothly without problems this summer. Follow these tips and hopefully, you won’t have to call us for repairs.

Replace Your Air Filters

Hopefully, you change your air filters on a regular basis (once every 3 months at the maximum, but once a month is even better) but if you haven’t changed it lately, make sure you do now. Dirt and debris extracted from the air will eventually build up and reduce the airflow. That means your air conditioner has to work harder to push the air through the system, which means you will pay more in utility bills.

Clean Around the Outdoor Condenser Unit

All winter long, your condenser unit sits outside where it’s exposed to wind, water, dirt, and dust. All debris, like leaves and sticks, should be removed from around the unit. Be sure to keep an eye out for any animals like mice, snakes, or birds that may have made a nest in or around your HVAC condenser unit. Also, check for weeds and vines that could be growing too close to your unit. You want to have two feet of clearance around it to make sure it can get sufficient airflow. While you can, clean around the outside of your unit by yourself, don’t open it up on your own to avoid any injuries. Any cleaning of the inside of your unit should only be performed by a professional.

Check Registers and Vents

Spring is a good time to clean the supply vents. Check that all of the registers are open and that air can flow freely through them. Make sure that furniture, rugs, and curtains aren’t blocking the registers. If the registers look dirty, remove them from the vents and vacuum them to remove dust and pet hair that may have accumulated over the winter. You can wash them with warm water and mild soap as well.

Turn On the Air Conditioner

Once you’ve got everything cleaned and prepped, turn on your AC to make sure air is flowing from the vents and that the air you feel is cool. We recommend you do this early in the spring before it gets too hot and you discover there is a problem. If the air doesn’t feel cool after letting the system run for several hours, give us a call and we’ll come and take a look.

Switch to a Programmable Thermostat

If you don’t have a programmable thermostat, consider upgrading. Programmable thermostats make it easy to use less energy by automatically raising and lowering the temperature in your home when you are asleep or away to save energy. By programming it according to the Department of Energy’s guidelines, you can save up to $200 a year on utility bills.

Schedule Your HVAC System Maintenance

No matter how old your system is, we recommend having a spring tune-up performed. One of our technicians will come to your home and check the refrigerant levels and electrical connections, adjust the tension on belts, replace any worn belts, tighten any loose parts, lubricate all moving parts, and make sure that your system is running efficiently.

heating and cooling Lancaster brothersToday’s heating and cooling equipment is much more sophisticated than systems of the past.  Air conditioners and furnaces are continually being improved to meet efficiency and environmental/regulatory goals. As technology advances, so must our skills. That’s why the technicians at Lancaster Brothers Heating and Cooling are always learning about new advances in furnaces, air conditioners, thermostats, geothermal equipment and more.

Modern HVAC Equipment

We’ve seen quite a few improvements in heating and cooling equipment in the last couple of decades. Because most ACs and furnaces last 10-15 years, many of our customers are surprised to learn about all of the new features there are when it comes time to replace their old unit. Newer units are quieter and more energy efficient thanks to some of these changes. Here are just a few that may take you by surprise:

Dual Stage Air Conditioners

20 years ago, there was no such thing as dual stage air conditioners. Today, we have systems with two-stage cooling, which means it runs at a low level most of the time and kicks into high gear when temperatures soar. This saves both energy and money.

Smart Thermostats

Smart thermostats are popular now too and Lennox offers a wide variety of smart thermostat options. Our technicians are familiar with all models so they are able to set them up and train our customers on how to use them to get the most comfort and savings possible. Smart technologies will continue to evolve and become integrated into our homes allowing us to control a home’s comfort levels from just about anywhere.

Our Technicians Receive Ongoing Training

Lennox is always working on ways to improve their products, so we attend trainings to keep us up to date on any changes in equipment installation and maintenance. During our slower service times, our technicians watch online training videos to stay abreast of all the changes. As a company, we’re required by Lennox to have 40 hours of training every year. Lennox also has in-store training that we attend. In fact, three of our techs will be attending a three-day WaterFurnace (our geothermal systems) training class this month (April).

Advanced Air Purification

Many air cleaning systems filter out particles. Some combat germs, and some fight odors, but only the Lennox PureAir™ Air Purification System addresses all three types of indoor air pollutants – airborne particles, germs and bacteria, and chemical odors and vapors. What that means in English, is that PureAir™ filters out 99.9% of all particles like pollen, dust, and pet dander. It removes over 95% of viruses such as MRSA, flu, and cold. Plus it removes and destroys over 50% of household odors and chemical vapors. Plus, unlike many other air cleaning solutions, PureAir™ doesn’t generate any ozone (a lung irritant). In fact, its carbon filtration actually reduces ozone generated by other sources in your home.

Finding the right Lennox thermometer can save you money.At Lancaster Brothers Heating and Cooling, we’re proud to sell and install Lennox brand air conditioners and furnaces. Many of our customers who have purchased a Lennox system ask us which thermostat they should choose to complement their new equipment. The Lennox Comfortsense models are the most popular. Here is a breakdown of the three models in the Comfortsense line. Hopefully, comparing the three will help you decide which one is right for you. 

We will go from least expensive to most expensive and explain all of the features that each one possesses. That way, you can decide which features are important to you and your family.

iComfort® M30 Thermostat

The iComfort M30 is a simple and stylish smart thermostat. It is compatible with both Lennox non-iComfort equipment as well as other brands of furnaces and air conditioners. It is also Amazon Alexa compatible, making it easy to use voice commands to control it with Amazon Echo or Amazon Dot devices. It also features a handy touchscreen which also allows you to use your voice to speak commands as well as a remote control function which lets you control it from anywhere with your smartphone.  


It takes comfort to a new level by working with your whole-house humidity control system to adjust the humidity level. It will even alert you if the system needs service or maintenance. The “Smart Away” mode uses your location services on your phone to know when you come and go and adjusts the temperature to save energy and maximize your comfort. It even provides Performance Reports. It summarizes the performance of the system and sends monthly summary emails showing month-to-month heating and cooling usage comparison and active service alerts

iComfort E30 Thermostat

This smart thermostat is the most versatile thermostat for your comfort needs. It boasts all the features of the M30 model, but also adds a 7” color touchscreen weather screen saver that not only displays the outdoor temperature but graphics that tell you what the weather is like outside. Not only that, but with its Auto (Perfect Temp) feature, it automatically decides between heating and cooling, but requires just one setpoint. 


The weather-on-demand feature provides the current outdoor temperature as well as a 5 or 7-day forecast. Its Climate IQ technology monitors indoor and outdoor conditions then automatically uses  your AC or heat pump to remove excess humidity keeping your home comfortable year round. It even features an Allergen Defender. It monitors the air quality and pollen levels in your local ZIP code and automatically turns the fan on to clean the home’s air when outdoor levels are high.

iComfort S30 Thermostat

This ultra-smart thermostat is the ultimate controller for precise comfort. It provides all of the wonderful features of the E30 including touchscreen, weather screensavers, weather on demand, and remote control, but It is only compatible with the Lennox iComfort enabled, variable capacity equipment to offer the highest level of comfort and overall system performance. This also allows it to add advance alerts. Instead of just telling you when the system needs service or maintenance, it will monitor all of the system’s components and use advanced diagnostics to identify the issue.


The S30 model also features the PureAir S Purification System. Built-in sensors monitor the life of both the filter and the Purifier UVA light so you don’t have to. When it’s time to change either, the PureAir S lets you know through the thermostat.


We Trust the Lennox Brand

No matter which thermostat you choose, your Lennox equipment will keep you comfortable all year long. If you’re still not sure which thermostat is right for you, check out this
comparison infographic or ask us and we will be glad to answer any questions you may have. If your furnace or air conditioner is on its last leg, we can install a new, quality Lennox furnace or AC. Check out our specials page for current manufacturer offers and discounts.

Set Your AC FanIf you’re not really familiar with air conditioners, or maybe you’re a new homeowner and haven’t had to deal with them too much yet, you may not realize that your air conditioner has two components: the part that cools and the part that moves the air. The thermostat temperature setting adjusts the part that cools. The fan affects the part that moves the air. The blower motor uses the fan to force the air through your ductwork to deliver cool air to all of the rooms in your home. There are two choices on your thermostat for your AC’s fan setting – “on” or “auto”. So which one is best? The team at Lancaster Brothers is here to help.

“On” Vs. “Auto”

Let’s first define what the fan settings mean. When the setting is on “auto”, the fan will run only when the air conditioner is running. When the setting is on “on”, the fan will run 24/7 whether the air conditioner is running or not. So, which is better? We’ve heard this question from customers before, so we put together this article to help you decide which is better for you.


The Argument for Setting the Fan to “On”

Keeping your fan running 24/7 keeps the air moving constantly which does have some advantages.

Cleaner Air

If you set your fan to the “on” position, it will run nonstop. One advantage is that you are constantly cycling the air through your filter, which means your indoor air will be cleaner. You may want to check the filter slightly more often in case dirt builds up faster. This could be helpful if you have an allergy or asthma sufferers in your home.

Can Help Reduce Hot and Cold Spots

Keeping the fan on creates a more even distribution of heated or cooled air, which can help if you have a room above a garage or in a partially finished basement that’s hard to keep cool.


The Case for Setting the Fan to “Auto”

There are several advantages to having your fan run only when your air conditioner is running.

Lower Energy Bills

Since the fan is always running when it is set to “on”, you’re using more energy than when the fan is set to “auto”. The average air conditioning unit has a 500-watt fan, which uses almost as much energy as a refrigerator uses during the course of a year. Running the fan constantly can increase your electric bill by about $50 a month.

Lower Humidity

While the air conditioning cycle is running, the indoor coil gets cold. Water from the air passing over it condenses on the coil. When your fan is on “AUTO,” moisture is able to drip from the cold cooling coils and drain outside because the air isn’t blowing across the coils. When the fan is running 24/7, that moisture doesn’t have a chance to drip outside. Instead, it blows back into your house, and, as a result, your AC then has to work even harder to suck that extra moisture out of the air. Your home will have lower humidity levels if you set your thermostat to “auto” instead of “on”.

Less Energy Loss through Leaky Ductwork

According to Energy Star, leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent. If you set your fan to “on” it will be running 24/7 so instead of air leaking out only when the AC is running, it will be a constant leak, thus increasing your total duct leakage.


Variable Speed Units Provide a Compromise between the “On” and “Auto” Settings

So, ultimately, the answer is up to you. If you have people with asthma or allergies in your home, cleaner air (the “on” position) may be your choice, but if you like the idea of energy savings, the “auto” setting is most likely your best choice. If you like the sound of the comfort and air quality improvements that the “on” setting can provide, but higher energy bills don’t sound too good, a variable speed unit may be your best choice. A variable speed unit runs nearly all the time (allowing for the advantages of the “on” setting), but it can operate at a number of different speeds depending on how much airflow is required (allowing for the energy-saving advantage so of the “auto” setting).


If Air Conditioner Isn’t Cooling Your Home, Lennox is For You

AC MistakesSummer has arrived, and with it, the scorching KC summer temps. Your air conditioner will be working at maximum capacity. Considering that your heating and cooling bills are responsible for roughly half of your energy bills and the average household spends about $2,200 on energy bills per year, these tips should go a long way in saving you some serious money. Plus, they’ll keep you feeling more comfortable too.


Mistake #1- Setting the Thermostat Too Low

When temperatures outside get extremely high, it can be tempting to turn your thermostat down even lower to keep things nice and chilly. What most homeowners don’t understand is that air conditioners are designed to maintain a 20-degree difference between inside and outside temperatures.

If the temperatures outside are in the 90s, your AC should be able to keep your home in the 70s. However, when temperatures skyrocket to the low 100s, it may only be able to keep your home in the high 70s or low 80s.

This doesn’t mean your air conditioner isn’t functioning properly. It just means you may have to lower your expectations on super hot days. Otherwise, your AC will just run nonstop costing you more and comforting you less. Constant running also creates a massive load on the system and can lead to your entire system freezing up. This is not what you want during the hottest days of the summer. To keep this from happening, find a temperature you can tolerate and leave the unit set there, even if you’re tempted to turn it down.

Mistake #2 – Not Using Ceiling Fans

While ceiling fans do not affect the temperature in your home, they do make you feel cooler due to the “wind chill effect”. By running your ceiling fans, you create air movement. As the air moves and cold air comes into contact with your skin, heat is lost. This heat loss is caused by conduction, the transfer of heat through direct contact. Because your body is losing heat faster than it would with no air movement, it feels colder than it really is. The nice thing is that you can turn your thermostat up a few degrees and not feel uncomfortable. TIP: In the summer, make sure your ceiling fan is rotating counterclockwise (when you look up at it) to push air down into the room.

Mistake #3 – Close the Blinds

Don’t let the sun undermine your air conditioner. Keep all blinds and curtains closed. Believe it or not, the sun can add exponential amounts of heat to any room through solar gain. Solar gain refers to the increase in thermal energy of a space as it absorbs incident solar radiation. The trapped heat thus causes solar gain via a phenomenon known as the greenhouse effect. Keeping the sun out will keep the temperature down throughout your entire house.

Mistake #4 – Change the Filter Monthly

Make sure you change your filters religiously, so as to avoid overworking your system. It sounds simple, and it is, but you’d be surprised at how many homeowners forget this little maintenance item. Pushing air through a dirty filter makes your air conditioner work harder than it has to. The Department of Energy says the average household spends about $2,200 a year on energy bills. When you change your air filter monthly, you can save from 5 to 15 percent on your utility costs. Dirty air filters worsen the air quality and can exacerbate symptoms of allergies. So changing your air filter gives you the added bonus of cleaner air.

A Tune-Up Will Increase Your AC’s Efficiency

Try these simple tips to lower your utility bill and feel more comfortable in your home. The 20-degree temperature drop is applicable when your system is in good working condition. If your AC has dirty cooling coils, frozen coils, poor airflow, or is low on refrigerant, the temperature drop it is capable of achieving will be much smaller. In order to make sure your system is running at peak efficiency, schedule a tune-up for your air conditioner.

Refridgerant LeakingIt’s a beautiful summer day, the sun is shining, the birds are chirping, the children are running through the sprinklers, and your air conditioner is blowing hot air…what a bummer. One common problem when your AC is blowing warm air is a refrigerant leak. Since the refrigerant is in a closed system, the only reason a system would be running low on refrigerant would be either it was undercharged during installation, or you have a leak. It does not deplete due to normal use, so it should not need to be refilled regularly.


1. Your Home Takes a Long Time to Cool

The term refrigerant refers to the chemical blend that cycles through the air conditioner absorbing heat and carrying it outside; it used to be commonly referred to as Freon, but only older systems would contain Freon because the EPA banned it due to its negative effect on the ozone layer. Today’s newer systems run on R410a (sometimes called Puron). Either way, if your home is taking a long time to cool, it could mean the refrigerant is running low.

2. Rising Energy Bills

As a result of the AC taking longer to cool down the house due to a refrigerant leak, you may see an increase in the cost of your energy bill. Refrigerant leaks cause your AC to work harder and longer. It will keep running and running but never reach the desired temperature.

3. Warm Air Coming from Vents

On a hot summer day, warm air blowing out of the vents in your house is the worst. Since refrigerant is responsible for absorbing heat and carrying it outside, when it leaks, the heat is not carried outside and the warm air blows into the house.

4. Frozen Evaporator Coils on Inside Unit, Ice on Outdoor Unit’s Line

Believe it or not air conditioners can freeze, although they are not supposed to. Low refrigerant can cause two parts of your AC unit to freeze. First is the evaporator coil, which is located in the indoor unit. Second, if the leak is large enough, the refrigerant lines leading to your outdoor unit will freeze. If either one of these parts of your AC are frozen, you definitely have a problem with your refrigerant.

5. Hissing or Bubbling Noise

If the leak is large enough, you will be able to hear it leaking out the refrigerant lines in either gas or liquid form. This tends to make a bubbling noise if it is liquid, and a hissing noise if it is gas.

The refrigerant is a potentially dangerous substance that should always be handled by a professional. This is not a problem that you should attempt to fix yourself.
