In Terrell, an air conditioner can run six months or more each year, often through long stretches of upper-90s afternoons. That kind of workload wears out parts, clogs coils and drains, and slowly chips away at efficiency. Regular maintenance keeps your system running the way it should, lowers the odds of a breakdown on the hottest day of the year and helps your equipment last longer.
Why seasonal maintenance pays off
- Fewer breakdowns. Most emergency calls start as small issues — a weak capacitor, a clogged drain, a dirty coil — that a tune-up would have caught.
- Lower energy bills. Clean coils and correct refrigerant levels let your system cool and heat with less electricity.
- Longer equipment life. A system that isn't straining simply lasts longer.
- Warranty protection. Many manufacturers require proof of regular maintenance to honor their warranty.
- Safety. Heating tune-ups include carbon monoxide and heat exchanger checks.
What's included in an AC tune-up
Our spring cooling tune-up covers:
- Inspecting and cleaning the outdoor condenser coil
- Checking refrigerant pressures and the temperature drop across the indoor coil
- Testing capacitors, contactors and electrical connections
- Checking the outdoor fan motor and indoor blower motor
- Flushing the condensate drain and testing the float switch
- Inspecting the indoor coil where it's accessible
- Checking the air filter and thermostat operation
You'll get a written summary of what we found — anything that needs attention now, and anything worth keeping an eye on.
What's included in a heating tune-up
For gas furnaces, we inspect the burners, igniter and flame sensor, check gas pressure, test the safety limits, inspect the heat exchanger and venting, and test for carbon monoxide. For heat pumps, we check refrigerant levels, the reversing valve, defrost operation and the backup heat strips. Every heating tune-up also includes airflow, electrical and thermostat checks.
How often should you schedule maintenance?
Twice a year is ideal in North Texas: cooling in the spring, before the heat arrives, and heating in the fall, before the first cold front. If you're only going to do one, make it the spring AC tune-up — summer is when a breakdown costs you the most in comfort, and when appointment times fill up fastest in Terrell.
What you can do between visits
- Replace standard 1-inch filters every one to three months — more often if you have pets or during heavy pollen seasons.
- Keep about two feet of clearance around the outdoor unit, and rinse off grass clippings and leaves.
- Keep supply and return vents open and unblocked by furniture or rugs.
- Watch the condensate drain line, and call us if water backs up into the pan.
When a tune-up finds a problem
If we spot something during maintenance, we'll explain what it is, how urgent it is and what it would cost to fix — in writing — before doing any repair work. Many issues can wait for a convenient time; others, like a failing capacitor in June, are worth handling right away. Already having trouble? Skip ahead to AC repair or heating and furnace repair. If your system is near the end of its life, our AC installation page explains what to look for in a replacement.
