Your air conditioner should be professionally serviced once a year — ideally in the spring before cooling season begins, typically March through May on the Denver Front Range. Annual maintenance is the single most effective thing you can do to extend your system’s life, catch small problems before they become summer breakdowns, and keep your equipment running at the efficiency it was designed for. Skipping maintenance for two or three seasons is one of the leading causes of premature compressor failure, which is by far the most expensive AC repair there is.
What Done’s Maintenance Visit Covers
A thorough Done AC tune-up is a comprehensive inspection and service — not a 15-minute visual check. Here is what our technicians examine and address on a standard visit:
- Refrigerant pressure check and leak inspection — low charge is the leading cause of poor cooling and compressor stress
- Condenser coil cleaning — Denver’s fine dust and late-spring cottonwood season clog outdoor coils faster than in humid climates
- Evaporator coil inspection inside the air handler
- Capacitor and contactor testing — these small electrical parts fail frequently and are cheap to replace during a tune-up but cause a full breakdown if they fail mid-summer
- Condensate drain inspection and clearing — a clogged drain causes water damage and can trigger safety shutoffs
- Electrical connection tightening
- Supply and return air temperature measurement to verify performance
- Blower wheel and motor amperage check
- Thermostat calibration verification
Why Colorado’s Climate Makes Annual Service Essential
Denver’s environment creates specific challenges that accelerate AC wear. The high-altitude UV index degrades plastic components, wiring insulation, and condenser coatings faster than at lower elevations. The Front Range is one of the most active hailstorm corridors in the country — a storm can bend condenser fins and reduce airflow without stopping the system, letting it run inefficiently for months before the homeowner notices. Colorado’s air, while famously dry, carries fine particulate dust (especially during windy spring months and wildfire season) that clogs condenser coils more aggressively than humid-climate dust, where moisture keeps particles weighted down. Cottonwood season in late May and June can blanket an outdoor unit in days.
What You Can Do Between Professional Visits
Between annual service calls, a few simple habits make a real difference. Change your air filter every one to three months depending on filter type, home size, and whether you have pets. A clogged filter restricts airflow across the evaporator coil, causing icing, reduced efficiency, and blower motor strain. Keep the area around your outdoor condenser clear of weeds, overgrown shrubs, and debris — 18 inches of clearance on all sides is a solid rule. After any hailstorm, inspect the condenser fins for visible damage. And if your system starts making new sounds, short-cycling, or struggling to reach the set temperature, call rather than wait until your next scheduled visit.
The Case for a Maintenance Plan
Done’s Care Club maintenance plan keeps you on schedule without having to think about it. Members receive annual cooling and heating tune-ups, priority scheduling (valuable when the entire Denver metro is calling on the first 90-degree day of the year), and discounts on any needed repairs. The plan pays for itself quickly when you weigh it against the cost of even a single diagnostic service call — let alone a mid-season emergency repair with after-hours premiums. Consistent documented maintenance also preserves most manufacturer warranties, which commonly require proof of professional annual servicing.
When to Get This Year’s Tune-Up on the Calendar
The best time is before the first heat wave. Denver temperatures can spike from the 60s to the 90s with very little warning in May or June. Shops fill up fast when the heat arrives. If your system hasn’t been serviced since last summer — or longer — this is the time to schedule. Done serves the entire Denver metro and Aurora, with convenient appointment windows.
