The Boulder80306 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

Short cycling — on and off every few minutes
Musty or burnt smell the first time the system runs
Skyrocketing utility bills with no change in usage
One or two rooms that never reach the set temperature
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.
Homes in Boulder County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
Peak cooling demand here runs June through August. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Boulder80306 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.
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 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.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
How much does an HVAC service call cost in 80306?
A diagnostic visit in Boulder typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
Are your technicians licensed and insured?
Every technician dispatched into Boulder is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
