What’s Included in an AC Tune-Up
EZ Air Conditioning & Heating ® takes maintenance seriously, and every tune-up includes a full inspection, deep cleaning, and performance check. Our goal is to catch small issues before they snowball into major repairs, and to make sure your system is running safely and efficiently.
Here’s what you can expect during a standard AC maintenance visit:
- System diagnostics and performance testing: We evaluate how well your AC is operating and flag any signs of early failure.
- Condenser and evaporator coil cleaning: Dirty coils reduce cooling capacity. We clean them for better airflow and efficiency.
- Electrical inspection and tightening: We check wiring and terminals to prevent overheating and electrical failure.
- Refrigerant level check: We test for proper pressure and inspect for signs of leaks or improper charge.
- Drain line flush: Clogged condensate lines can lead to water damage. We make sure they’re clear and draining properly.
- Motor lubrication and fan check: We reduce friction in moving parts to help your unit run quieter and last longer.
- Thermostat calibration: We make sure your thermostat is reading accurately and communicating properly with the system.
Our team takes the time to get it right, and we’re happy to answer questions or explain anything we find along the way.

Came out on a Saturday when my AC went out. He was able to have it running in no time. He later came back to do maintenance on it & was very thorough. I highly recommend EZ Air Conditioning & Heating and their staff.

The installation crew did a great job. They left the inside and outside area clean. Stayed until we knew how to use the new system. We recommend EZ Air Conditioning & Heating without hesitation!

The cost of the same day service and resolution was surprisingly, and thankfully, affordable... I would definitely recommend calling EZ Air Conditioning & Heating if the need arises. There's no one else I would call for AC help!

Special thanks to Jonathan, Chris, & the install team - we couldn’t be more happier. We wanted to work with a company that had a good reputation as well as an authorized Carrier dealer and we got exactly that.
