THE PROBLEM
MOST AC REPAIRS START AS SMALL PROBLEMS NOBODY CHECKED
A clogged filter, a dirty coil or a drain line starting to back up won't stop your AC today. They make it run longer, pull more power and wear out parts faster.
Then a 100° afternoon in Celina pushes it past its limit. The checklist shows you what to look for so you can catch it first.

Dust, pollen and cottonwood clog filters and coils fast
Emergency calls in peak season mean longer waits
INSIDE THE CHECKLIST
5 CHECKS YOU CAN DO THIS WEEKEND
A preview of the homeowner section. The full guide covers 12 checks plus the warning signs that need a technician.
1
Replace or clean the air filter
Hold it to the light. If you can't see through it, swap it.
2
Clear around the outdoor unit
Keep 2 feet of open space free of grass, leaves and fencing.
3
Check the condensate drain line
Look for standing water or a slow drip near the indoor unit.
4
Test the thermostat
Drop it 5° and listen for the system to kick on within a minute.
5
Feel the supply vents
Air should feel noticeably cooler than the room within 10 minutes.
WHEN TO CALL A PRO
SIGNS YOUR AC NEEDS A TECHNICIAN
- Warm air from the vents with the thermostat set to cool
- Ice on the refrigerant lines or indoor coil
- Short cycling: turning on and off every few minutes
- Grinding, squealing or buzzing from the outdoor unit
- A sudden jump in your electric bill

WHY IT MATTERS
A MAINTAINED SYSTEM COSTS LESS TO RUN
Neglected equipment keeps cooling, but it does it slowly and expensively. The fix is usually simple: a clean filter, a clear drain and coils that can move heat.
The checklist covers what you can do yourself. For everything else, our technicians handle a full inspection on every make and model.
