Furnace Repair and HVAC Services in Boulder, CO

Furnace Repair in Boulder, CO

Repair is usually the front door to a larger conversation, but it starts with getting the heat back on. These are the calls we take most often from Boulder addresses:

• No heat at all, with the thermostat calling and the furnace never firing
• Air that starts warm and turns cool partway through the cycle
• A furnace that ignites, runs briefly, then shuts down and tries again
• A failed igniter or a dirty flame sensor stopping ignition
• A blower motor that hums, squeals, or will not spin up
• A cracked or aging heat exchanger, which is a safety issue rather than a comfort one

Every visit follows the same order. The technician arrives, listens to what the system has been doing, then tests the ignition sequence, gas pressure, safeties, airflow, and electrical components until the actual cause is confirmed. You get the diagnosis and a fixed price before any parts come off the truck, and we carry common igniters, sensors, capacitors, and motors so most repairs finish in the same visit.

Dual fuel, which is most of what we install

The gas furnace already in the house stays exactly where it is. We pair it with a cold-climate heat pump installation in place of the outdoor unit, and the two systems hand off to each other. The heat pump carries the mild and moderate hours, which is the large majority of a Boulder heating season, and the furnace takes over on the coldest stretches when gas heat is the more sensible way to hold the house. You get air conditioning from the same outdoor unit all summer.

This is the majority of our installations because it fits how Front Range houses are actually built and heated, and because it leaves you with a system that has a second source of heat when the temperature falls hard overnight.

All-electric ductless, for homes with no ductwork

Where there is no duct system to work with, mini splits handle both heating and cooling on their own, zone by zone. The system runs without a furnace, ductwork, or a central air handler. This is the path for homes built with radiators, baseboard, or wall heat, and for rooms a central system was never going to reach.

Cold-climate rated equipment is what makes either path work in Boulder. That rating is not a marketing label. It means the compressor and refrigerant circuit are engineered to keep producing useful heat well below freezing, down into single-digit and sub-zero outdoor temperatures, rather than falling off to nothing the way older heat pumps did once the weather turned. We size and select that equipment to the house, its insulation, and its window load, not to the capacity printed on the unit being removed.

When you ask us for a quote on a failing outdoor unit, you see both numbers: the heat pump and the straight air conditioner, with rebates figured in, so the comparison is yours to make with real figures in front of you.

Ductless Mini Splits for Boulder Homes Built Without Ductwork

Boulder's older housing stock near downtown and University Hill was largely built before central forced air. Radiators, baseboard heat, and wall units are common, and there is often no duct chase anywhere in the house to run new trunk lines through. Finished attics, basements, sunrooms, and additions run into the same problem from the other direction: the original system simply never reached them.

A multi-zone ductless system solves that without opening finished plaster. An outdoor unit connects to individual indoor heads through small refrigerant lines, and each head heats and cools its own room on its own setting. That is what makes it work in these houses:

• No ducts to cut into lath, plaster, or original trim
• Room-by-room temperature control instead of one thermostat for the whole floor
• Heating and cooling from the same equipment, in rooms that previously had neither
  

• A practical way to condition an addition, sunroom, or finished basement without resizing the central system
• Quiet operation, which matters in a bedroom or a home office
  

Outdoor Unit Placement in Boulder's Historic Districts

Boulder has ten designated historic districts. If a property sits inside one, or is individually landmarked, exterior changes require review and approval through a Landmark Alteration Certificate, and mechanical equipment is among the most common types of work that needs one.

We plan condenser and mini-split placement with that review in mind rather than after the fact, and we work with homeowners on siting and screening so the equipment goes where it will perform well and where it fits the property.

HVAC Maintenance in Boulder

A high-efficiency furnace, heat pump, or ductless system is a significant investment, and maintenance is how you hold its performance and its warranty coverage over the years it is supposed to last. A furnace tune-up cleans and tests the burners, igniter, flame sensor, heat exchanger, blower, and safeties. An AC or heat pump tune-up checks refrigerant charge, coil condition, defrost operation, electrical connections, and drainage before the season turns.

The VO Comfort Club covers two documented tune-ups a year, one for heating and one for cooling, scheduled rather than remembered. You get a written record of what was tested and what was found each time, which matters when a manufacturer warranty claim depends on proof of maintenance.

Rebates and Financing on a Boulder Upgrade

Boulder's electric service is Xcel Energy, and Xcel rebates on high-efficiency heating and cooling equipment come back to you at the front of the job. We apply the rebate as an instant discount on our invoice and then chase the reimbursement from Xcel ourselves, so the number you see is already net of it.

Power Ahead Colorado works the other way on purpose. You select us as your participating contractor, which is what starts the process, and the rebate is paid directly to you rather than added to the price and subtracted again. That keeps your actual bottom line honest and puts the program money in your hands on top of it.

Colorado also has a statewide heat pump tax credit administered by the Colorado Energy Office, a flat credit claimed by contractors registered with that program.

On the Xcel Energy and Power Ahead Colorado programs, we do the paperwork. Wells Fargo Home Projects financing is available for homeowners who would rather spread the cost of a system over time than pay it in one piece.
