Most cooling calls come down to a handful of parts. Knowing the names helps you follow what the contractor tells you.
The capacitor gives the compressor and fan motor the push they need to start. It weakens in the heat and is the most common summer repair. The contactor is the switch that turns the outdoor unit on. When its contacts burn, the unit will not start.
This fan pulls air through the outdoor coil. If it stops, the unit overheats and shuts off. A humming unit with a still fan points here or to the capacitor. See AC fan not spinning.
An AC does not use up refrigerant. If it is low, it is leaking. Most systems installed before 2025 use R-410A, and newer ones use R-454B. Federal EPA rules control who can handle refrigerant, so this is always a contractor job.
Low airflow or low refrigerant can freeze the evaporator coil. A clogged condensate drain fills the pan and trips the float switch, which shuts the AC off. The compressor is the heart of the system and the most serious repair when it fails.
1.
Set the thermostat to Cool and a few degrees below room temperature. Replace the batteries if the screen is blank.
2.
Check the breaker panel for a tripped AC or furnace breaker. Reset it once only.
3.
Check the outdoor disconnect box next to the unit is switched on.
4.
Pull the filter. If it is gray and packed, replace it.
5.
Look in the pan under the indoor unit. Standing water can mean the float switch has shut the AC off.
6.
Clear grass clippings, leaves and cottonwood fluff from around the outdoor unit.
If you see ice, turn the thermostat from Cool to Off and leave the fan on to melt it. Do not open the outdoor unit, touch wiring or add refrigerant yourself.
Still not cooling? Call: (303) 647‑3227At this elevation the afternoon sun is strong, and two-story homes in Stonegate, Stroh Ranch and Meridian feel it upstairs first. Dry air carries dust that coats the outdoor coil. Cottonwood fluff in early summer can block it completely.
Douglas County gets hail most summers. Hail can flatten the thin fins on the outdoor coil, which cuts airflow and makes the system work harder. If cooling dropped after a storm, mention it when you call.
A single part on a newer system is almost always worth repairing. An older system that needs a compressor or a large refrigerant repair is a different conversation, especially if it still uses R-22, which is no longer made. Ask the contractor to compare both. Read more on AC installation.

Have the brand and model ready. They are on a label on the outdoor unit. HVAC Parker CO does not do the work or set prices. The contractor handles the visit, the diagnosis and the bill.
Talk to a cooling contractor: (303) 647‑3227The most common causes are a weak capacitor, a dirty outdoor coil, a refrigerant leak or a frozen indoor coil. A dirty filter can cause the freeze. See AC not cooling for more.
It depends on the part, the system and the time of the visit. A capacitor and a compressor are very different jobs. The contractor sets the price and can talk it through before any work starts.
No. Federal EPA rules control who can handle refrigerant. If it is low, there is a leak, and adding more only hides the problem.
If it needs one small part and still cools well, often yes. If it needs a compressor or uses R-22, ask the contractor to compare repair with replacement.
You can call any time, including nights, weekends and holidays. Ask the contractor when they can come out.
