Air conditioning maintenance prevents problems (efficiency, lifespan & warranty)
Preventive care—clean coils, drain line flush, lubrication of motor bearings, amperage checks—prevents breakdowns. Dirt acts like insulation on coils, raises pressures, spikes energy use, and crushes cooling capacity. Keeping filters and coils clean and verifying refrigerant charge, contactor, and capacitor lowers the risk of costly AC repairs and keeps you square with warranty requirements.
What are the signs that my AC unit needs maintenance?
In Colorado, the best time for AC maintenance is spring (and a quick post-summer check helps too). If you’re wondering how often ac tune up Colorado, we recommend once per year for homes and twice for commercial or heavy use. Watch for reduced airflow, hot spots in the home, musty odors, noisy startups, or dust at the registers—each is a nudge to book a tune-up and preserve performance.

Air conditioner not blowing cold air? here’s what to check
Before you call, double-check the thermostat (mode cool, fan auto, setpoint below room temp), the air filter (replace if dirty), and the breaker. If there’s no change, you may have a frozen coil from low airflow, low refrigerant from a leak, or a failed capacitor keeping the compressor from starting. That’s where our what to check before calling ac repair Commerce City visit pays off—we handle the dirty filter no cold air fix, measure pressures, amperages, and temps, and get your system back to cold, steady cooling safely.

We treat causes—not just symptoms—with deep cleaning, a drain line flush, and optional IAQ upgrades like UV light installation when appropriate.
