Service Areas
One call connects Castle Rock homeowners with an independent local contractor for HVAC repair in Castle Rock, CO. The line covers zip codes 80104, 80108 and 80109, from the homes near downtown out to the newer neighborhoods on the edges of town. Furnaces, boilers, heat pumps and air conditioners are all covered.
Call (303) 647-3227
Coverage takes in the whole Town of Castle Rock. That includes The Meadows, Founders Village, Plum Creek, Crystal Valley and Red Hawk, plus the older streets around downtown. The north part of 80108 also reaches toward Castle Pines.
If you are on acreage outside town limits, call and ask. Many contractors on the line work the rural roads too, and we will tell you plainly if your address is too far out.
The first cold night of the season brings the same short list of calls. A dirty flame sensor shuts the burners off a few seconds after they light. A cracked hot surface ignitor stops them lighting at all. A filter left in since spring trips the limit switch.
Some older and custom homes here heat with a boiler and radiant floors instead of a furnace. A circulator pump, a zone valve or a low-pressure fault can leave one part of the house cold. Read more on furnace repair and boiler repair.
Call about heating repair: (303) 647‑3227Summer afternoons are hot and the sun is strong, and two-story homes in The Meadows and Crystal Valley put a lot of load on one system. The usual failures are a weak run capacitor, a burned contactor, a condenser coil clogged with dust or cottonwood, and a frozen evaporator coil.
Hail is part of summer along the I-25 corridor. Flattened fins on the outdoor unit cut airflow, and the AC runs longer to keep up. See AC repair for the common symptoms.
Call about AC repair: (303) 647‑3227Castle Rock sits higher than most of the Denver metro. The air is thinner, so a gas furnace has to be set up for the altitude when it is installed. One left on its factory settings still heats the house, but it can burn rich and soot the heat exchanger over time.
The housing mix matters too. Downtown homes often have systems that have seen many winters. Newer neighborhoods have high-efficiency furnaces that vent through plastic pipes in a side wall, and a snow drift can block them and shut the furnace off. Tell the contractor the age of your system and your neighborhood when you call. It helps them narrow the cause.
You can call any time, including nights, weekends and holidays. No heat on a January night is worth a call right away, before pipes on outside walls get cold. The contractor will tell you when they can come out. More on the emergency HVAC repair page.

Calls from 80104, 80108 and 80109 are covered. If you are on acreage outside town, call and ask. We will tell you if coverage does not reach your address.
Yes. Thinner air means less oxygen for combustion, so gas furnaces are adjusted for altitude when they are installed. If yours was never adjusted, ask the contractor to check it on the visit.
You can call any time, including weekends and holidays. Weekend visits depend on the contractor schedule, so ask when you talk.
