Residential HVAC in Boulder, CO

No Surprises

Clear Pricing Before Any Work Starts

Before we start any repair, we figure out exactly what's wrong. Our technicians check the age and tonnage of your system, the refrigerant charge, the heat exchanger and coils, and the condition of your ductwork. Then you get a straightforward recommendation and the complete price up front, whether the job is swapping a worn capacitor or replacing the whole system. No hidden fees, no surprise add-ons.

Many HVAC problems stay hidden until a failure is well underway. Refrigerant seeps out through pinhole leaks in the evaporator coil, blower bearings wear slowly, and a weakening capacitor gives no warning until the compressor won't start on the first hot day. If you notice weak airflow, rising energy bills, ice on the refrigerant lines, or rooms that never reach the thermostat setting, schedule an inspection right away. An early diagnosis often keeps a repairable issue from becoming a replacement.

We also help homeowners plan ahead. Most air conditioners and furnaces last 12 to 18 years, and a planned replacement is always cheaper and less stressful than an emergency swap during a heat wave or cold snap. Our technicians know the climate demands common to Boulder and how they affect equipment life, so we can tell you honestly whether your system has years left or is living on borrowed time.

Preventive Care

Maintenance Plans for Boulder Homes

Routine maintenance is the most reliable way to keep your home comfortable year-round. Regular service prevents failures before they start, keeps coils and burners clean, and catches small faults while they're still inexpensive to fix. At Boulder HVAC, every plan is built around your home's actual equipment, with scheduled visits that cover coil cleaning, refrigerant charge verification, capacitor and contactor testing, burner and heat exchanger inspection, condensate drain clearing, filter replacement, and a static pressure check across the duct system.

Every maintenance plan we write is a little different. A furnace in its later years needs a closer look than a brand-new heat pump, and a dusty area means condenser coils foul faster. We build spring cooling and fall heating visits around your system, your climate, and how your family uses it, so every tune-up helps keep the system efficient and extends the life of the equipment you've already paid for.

The savings show up quickly. Clean coils move heat more efficiently, a correct refrigerant charge keeps the compressor from overworking, and a fresh filter spares the blower motor. Next to the cost of replacing a system even one year early, a maintenance plan is a bargain.

Equipment Sized for Your Actual House

Proper sizing matters more than most homeowners realize. Before recommending new equipment, Boulder HVAC works through the details that determine your home's heating and cooling load: square footage, insulation, window exposure, and duct layout. That gives you a system that runs in long, efficient cycles, controls humidity, and holds every room at the temperature you set.

We walk you through the options for most homes, especially growing families with rising comfort demands. A single-stage system that served a small household rarely satisfies a finished basement and two added bedrooms, and a modern two-stage or variable-speed heat pump can hold tighter temperatures while cutting energy use significantly. If you're weighing furnace-and-AC against a heat pump, or ducted against ductless, our technician will lay out the honest trade-offs: SEER2 efficiency ratings, operating cost, electrical and venting requirements, and upfront installation work, so you can pick what fits your home and budget.

Heating and Cooling Problems We Solve in Boulder

The majority of service calls we get in Boulder come down to a handful of recurring problems. The AC runs but the air never gets cold. The furnace won't ignite or keeps short-cycling. The evaporator coil freezes solid, the condenser hums without starting, or a ductless head flashes an error code. Add refrigerant leaks, clogged drains, and forgetful thermostats, and you have the full list. Our technicians handle all of them, starting with the exact part that failed.

Some problems are mostly a nuisance, while others pose real risks. A weak capacitor simply keeps the compressor from starting, but a cracked heat exchanger can leak combustion gases into your living space, and a blocked condensate drain can quietly ruin a ceiling. We match the fix to the failure: capacitors, contactors, and fan motors on cooling systems, igniters, flame sensors, and control boards on furnaces, sealed and repaired ductwork where conditioned air is bleeding into the attic, and refrigerant recovered and recharged after a repaired leak. Whatever you're facing, our team has the training and parts to handle it.
