Getting Your HVAC Ready for an Oklahoma Summer
When an Oklahoma summer kicks in, AC systems run almost nonstop — and HVAC companies get booked out for days. A little prep in spring can save you a sweaty week and an emergency repair bill.
DIY checklist (spring)
- Replace the air filter. Check monthly in summer; dusty Oklahoma wind and cottonwood season clog filters fast.
- Clean around the outdoor unit. Clear 2 feet of space — grass clippings, leaves, cottonwood fluff, and weeds choke airflow.
- Gently rinse the condenser coil with a garden hose (power off first; no pressure washer).
- Check for hail damage. Bent condenser fins after a hailstorm reduce efficiency — and may be covered on a hail claim.
- Test the thermostat. Replace batteries; consider a programmable or smart thermostat.
- Check the condensate drain line for clogs (a common cause of water around the indoor unit).
- Look at your ductwork in the attic for disconnected or crushed sections.
- Make sure supply and return vents aren't blocked by furniture or rugs.
When to call an HVAC pro
- The system blows warm air or short-cycles
- Ice on the refrigerant lines or indoor coil
- Strange noises (grinding, squealing, banging)
- Breaker trips when the AC starts
- Energy bills jump without explanation
- System is 12–15+ years old and needs frequent repairs
A spring tune-up usually includes checking refrigerant, cleaning coils, testing capacitors and contactors, and measuring temperature split.
Repair or replace?
Consider replacing when:
- Repairs would cost a large share of a new system
- Your system uses R-22 refrigerant — U.S. production and import of R-22 ended January 1, 2020, so recharging an old system now relies on limited recycled supply and can be expensive
- Comfort is uneven and bills are high
Ask about high-efficiency (SEER2) systems and utility rebates. PSO customers can check the Power Forward with PSO program, which has offered rebates on qualifying heat pumps and smart thermostats; OG&E customers should check OG&E's residential energy-efficiency programs. Rebate amounts, eligible equipment, and filing deadlines change each program year (and usually require submitting within a set number of days after install), so confirm on the utility's site before you sign.
Licensing
