Done’s AC maintenance visit is a thorough, multi-point inspection and tune-up of your entire cooling system — both the outdoor condenser unit and the indoor air handler or evaporator coil. The goal is to verify that every component is operating correctly, identify anything that’s marginal or failing before it causes a breakdown, clean surfaces that accumulate dirt and restrict performance, and leave your system ready to handle a full Colorado cooling season. Here’s exactly what our technicians do.

Outdoor Condenser Unit

The outdoor unit is where the system rejects heat from your home into the outside air. Done’s technicians inspect and service:

  • Condenser coil inspection and cleaning — dust, cottonwood seeds, and debris restrict airflow and reduce heat transfer. Denver’s dry, dusty air and cottonwood season in late spring make coil cleaning a high-value step here.
  • Condenser fan motor and blade inspection — checking for wear, cracks, and proper blade pitch
  • Compressor electrical draw measurement — amperage readings reveal whether the compressor is straining
  • Capacitor testing — capacitors fail gradually; a weak capacitor is caught here before it fails on the hottest day of the year
  • Contactor inspection — worn contactor points cause hard starts and accelerate compressor wear
  • Electrical connection inspection and tightening — loose terminals create heat and arcing risk
  • Refrigerant pressure check — verifies charge is within manufacturer specification
  • Visual inspection for refrigerant leak indicators at fittings and coil sections

Indoor Air Handler and Evaporator Coil

The indoor side is equally important. Done’s technicians check:

  • Evaporator coil condition — a coated coil loses heat absorption efficiency; cleaning is performed if needed
  • Blower motor amperage and operation — a straining blower motor reduces airflow and adds to electricity consumption
  • Blower wheel inspection — accumulated debris on the wheel blades is a common and overlooked efficiency killer
  • Condensate drain line check and flush — a clogged drain causes water overflow that can damage ceilings, walls, and the air handler itself
  • Air filter check — a technician will note the filter condition and replace it if one is provided, or advise on replacement schedule
  • Supply and return air temperature differential — this delta-T measurement confirms the system is achieving proper cooling across the coil

Controls and System Operation

Beyond the mechanical components, Done’s technicians verify the full system operates correctly as a unit: thermostat calibration and operation, wiring connections at the control board, and a complete system run test to confirm proper startup, operation, and shutdown sequences. If your home has a smart thermostat, the technician will confirm it’s communicating correctly with the equipment.

Why Colorado Homes Benefit from Thorough Maintenance

Denver’s combination of high altitude, low humidity, and intense UV creates wear patterns that differ from lower-elevation markets. Thinner air means the system moves less heat per cubic foot of airflow, so any restriction — dirty coil, weak blower, clogged filter — compounds more noticeably in performance terms than it would at sea level. High-altitude UV degrades rubber insulation on refrigerant lines and electrical wiring faster than in most markets. Done’s technicians check these things as part of a complete visit, not as extras.

What You Receive After the Visit

At the conclusion of the visit, Done’s technician provides a written summary of the system’s condition, any findings noted during the inspection, and any recommendations for repair or upcoming attention. Nothing is done without your authorization and upfront pricing — if a repair is needed, you decide whether to proceed before any work begins. The written service record also documents the visit for warranty purposes.

Care Club Membership Makes Annual Maintenance Easy

Done’s Care Club membership includes annual maintenance visits with priority scheduling — so when spring appointment slots fill up fast, members get first access. Membership also includes discounts on repairs and other benefits that make the plan pay for itself quickly if any service is needed during the year.
