Heating and air conditioning service built around Boulder
Dry air, wide day-to-night swings and high altitude all change how combustion and refrigerant systems behave. Our Boulder teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
Around Boulder, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Because Colorado runs high-efficiency gas furnaces with central air, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Boulder80309 HVAC questions, answered
What does a new system cost in Boulder?
A complete residential replacement in the 80309 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.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Boulder we see algae and dust clogging drain lines constantly during June through August. It is a fast fix but ignoring it ends in ceiling damage.
Do you service commercial and light commercial properties?
Yes. Around Boulder we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
What brands do you service in Boulder?
All of them. Our 80309 technicians are trained on Lennox, Goodman, Heil, American Standard 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.
How often should I change my filter in 80309?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Boulder with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
