Heating and air conditioning service built around Boulder
Homeowners across Boulder call us when the system simply will not keep up. Dry air, wide day-to-night swings and high altitude all change how combustion and refrigerant systems behave. That is why we staff a live dispatch line around the clock instead of routing you to a queue.
Because Colorado swings between seasons quickly, a lot of our Boulder calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
The busiest week of our year in Boulder is the first stretch of sustained june weather. Systems that idled all season fail in clusters.

Boulder80304 HVAC questions, answered
How quickly can a technician get to Boulder?
For the 80304 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
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 Boulder, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Boulder see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
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.
What brands do you service in Boulder?
All of them. Our 80304 technicians are trained on Heil, Mitsubishi Electric, American Standard, Trane and essentially every other residential brand sold in Colorado, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Colorado, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
