Call Lancaster For A New Heating and Cooling System
Lancaster Brothers also installs new furnaces, air conditioners, and heat pumps in the Olathe area. When it is time to replace your old heating and cooling unit, we can help you select a new system that will meet your home’s requirements. Once you select a new furnace or air conditioner system, we can immediately dispatch our staff to deliver and install the new unit. All of our installation technicians are certified to handle any furnace, air conditioner, or heat pump installation.
New technology is available that can help you save money on your utilities and make your home more comfortable. This is especially important in those 2-story Olathe homes, where it seems like the upstairs bedrooms are never cool enough in summer. Lancaster Brothers can recommend a system that can help with that issue.
Install A Geothermal System In Your Olathe Home And Save Money
Lancaster Brothers are also experts in geothermal heating and cooling. Geothermal systems use the earth’s natural temperature to help keep your Olathe home warm in the winter and cool in the summer. Geothermal heating and cooling systems are the most efficient system you can put in your home. And now, tax credits are available until 2016 that will allow you to recoup up to 30% of the entire geothermal installation. This helps bring the cost of the project more in line with installing a really high efficiency furnace and air conditioner. With the additional savings on your utility bills, a geothermal system pays for itself in about 7-8 years. After that, the system starts to pay you!
Geothermal heat pump systems can be installed in both residential replacement and new construction applications. The tax credit is also available if you are building a new home. Call Lancaster Brothers today, and they will provide the answers to your geothermal questions at your Olathe home.
We Install Humidifier, Thermostats, and Other Indoor Air Quality Products
Lancaster Brothers also can install humidifiers, programmable thermostats, and other indoor air quality products in your Olathe home. A humidifier is really important in the winter, because it adds needed moisture into your home. You’ve probably noticed the static electricity, itchy skin, and even cracked drywall. This is because your home needs a whole-house humidifier installed. A home with the proper moisture in winter can also feel warmer, which means you can sometimes turn down your thermostat a degree or two. Call Lancaster for a humidifier installation today!
We can also install other indoor air quality products, like media filters and electronic air cleaners. These type of air filters keep the air clean in your home, and can even kill allergens and bacteria floating around your air. Since we spend a lot of times indoors in the Olathe area, it’s important to make sure the air you breathe is clean, especially if you suffer from allergies. Call us today, and our comfort specialists can talk to you about the different types of air filters available for your home.
