Why Oklahoma summers are tough on AC systems
Long stretches of triple-digit heat mean your AC can run almost nonstop. Add red-dirt dust and cottonwood fluff clogging outdoor coils and systems work even harder.
Most AC failures we see happen during the first major heat wave, when a weak capacitor or low refrigerant finally gives out.
Warning signs to watch for
Warm air from vents, ice on the copper lines, a unit that runs constantly without reaching the set temperature, or a sudden jump in your electric bill are all signs to call a technician.
Simple things you can do
Change your filter every 1–3 months, keep two feet of clearance around the outdoor unit, and gently rinse the coil with a garden hose. A spring tune-up catches most problems before the heat arrives.
