The Denver80243 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Water pooling around the indoor unit or ceiling stains
Thermostat reading several degrees off from reality
Heat pump stuck blowing cold air in heating mode
No cool air, or air that is barely cooler than the room
Breaker trips every time the system starts
Furnace lights then shuts down after a few seconds
Heating and air conditioning service built around Denver
If your high-efficiency gas furnaces with central air has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Denver generates some of the highest call volume we handle in Colorado. Dry air, wide day-to-night swings and high altitude all change how combustion and refrigerant systems behave.
Around Denver, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Heating season here is October through April. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Denver80243 HVAC questions, answered
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Colorado is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Do you offer maintenance plans?
We do. A two-visit plan in Colorado covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Denver, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What does a new system cost in Denver?
A complete residential replacement in the 80243 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Why is my furnace short cycling?
Short cycling in Denver most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
