How Often Should I Schedule an AC Service?
We recommend scheduling an AC service at least once a year, ideally in the spring before the summer heat hits. Annual maintenance helps your system run efficiently, lowers energy costs, and reduces the chance of unexpected breakdowns during peak usage.
If you have an older unit, rely heavily on your system, or manage a commercial property, twice-yearly service, in the spring and fall, can provide even greater reliability and performance. Regular maintenance not only extends the life of your equipment but also helps your space stay cool and comfortable when it matters most.

8 Warning Signs Your Air Conditioner Needs to Be Repaired
Even a well-maintained air conditioner can develop issues over time, especially during Olathe’s long, hot summers. We recommend monitoring your system’s performance so you can more easily identify when something is wrong. Even issues that appear to be minor can worsen, leading to more severe damage and costly repairs down the line, so don’t hesitate to call our experts for an inspection.
Common warning signs you need to schedule an AC repair include:
- Warm or weak airflow coming from your vents.
- Unusual noises like banging, grinding, or rattling during operation.
- Foul or musty odors when the system is running.
- Frequent cycling on and off, even when the temperature is stable.
- Rising energy bills without increased usage.
- Moisture or leaks around the AC unit.
- Uneven cooling or hot spots in different areas of your home or building.
- Thermostat issues or inaccurate temperature readings.
If you're experiencing any of these symptoms, don’t wait – addressing small problems early on can prevent a full system breakdown. Our licensed and insured technicians are ready to diagnose and repair the issue quickly and professionally.
