Pre-Summer AC Checklist for Houston Homeowners
Houston summers put a long, sustained load on an AC system. A few checks before the heat sets in can catch small issues before they become no-cooling emergencies.
What to Check Before the Heat Arrives
Before assuming the worst, rule out the simple stuff:
- Replace or clean the air filter if it hasn’t been done recently.
- Clear leaves, grass clippings, and debris from around the outdoor unit, keeping at least a couple feet of clearance on all sides.
- Test the system on a mild day by running it long enough to confirm it’s producing cold air and cycling normally.
- Check that the condensate drain line isn’t already showing signs of a slow clog from the offseason.
When to Schedule a Professional Check Instead of a DIY Look
A few situations are worth having a technician look at rather than continuing on your own:
- The system didn’t run at all during a mild-weather test.
- You noticed ice, water, or unusual odors during the test run.
- You heard unusual noise on startup that wasn’t there before.
- The system is older and hasn’t had a professional look in over a year.
- You’ve noticed rooms cooling unevenly, which can be worth a look — see our guide on ductwork and airflow problems.
Timing It Right
Doing this in early spring, before the first real heat wave, gives enough lead time to schedule a repair if something turns up, rather than discovering a problem during the first 100-degree week.
A full maintenance visit covers items — like refrigerant charge and electrical component testing — that go beyond what’s practical to check without training and equipment. Ask about maintenance plan options when you call.
Common Questions
Doing this in early spring, before the first real heat wave, gives enough lead time to schedule a repair if something turns up, rather than discovering a problem during the first 100-degree week.
The basic checks — filter, clearance around the outdoor unit, listening for noise — are reasonable for most homeowners. Anything involving opening electrical panels or refrigerant lines is best left to a technician.
It’s a good supplement, but a full maintenance visit covers items that aren’t practical to check without training and equipment. Ask about maintenance plan options when you call.
