Complete Home Comfort Services in Boulder, CO
When a windstorm knocks out your heat and jams your garage door in the same night, we handle both in a single visit. Our technicians service furnaces, boilers, air conditioners, heat pumps, water heaters, drains, sewer lines, and garage doors, providing complete home services for your Boulder home. We size and tune equipment for the 5,400-foot elevation, know how thin air changes the way your appliances burn, and account for it on every service.
Count on our team for service in every part of Boulder, from the Hill and Mapletown to South Boulder and Gunbarrel. Whether you live in a 1960s build or a brand-new townhome, we provide services for the way your home was built.
AC Repair and Cooling Solutions for Boulder Summers
We provide AC repairs in Boulder that stand up to the late-summer heat and mountain wildfire smoke. With rising temperatures and smoky days that keep windows shut, you need a system that’s ready for the Colorado summers.
Our NATE-certified technicians service central ACs, mini-splits, heat pumps, and evaporative coolers for homeowners across the city. Whether you need air conditioning repair after a hailstorm, you’re due for an annual mini-split tune-up, or you’re ready to retire your rooftop cooler, we’ll keep your home cool all season.
HVAC Installation and Energy-Efficient System Upgrades
If your AC breaks down every summer or your furnace is nearing 20 years old, it’s time to consider an upgrade. We install furnaces, ACs, heat pumps, and full system replacements, with honest recommendations about what’s right for your home and budget. We’ll start by inspecting your system to assess its condition and lay out HVAC repair and replacement costs side by side so you can make the right decision for your home.
Making an upgrade? Installing a new, high-efficiency HVAC system can help you qualify for rebates and electrification incentives from the city and Xcel. We’ll explain what you qualify for and handle the paperwork on your behalf.
Heating and Furnace Services for Cold Colorado Weather
When the first cold snap hits and temperatures drop into the teens overnight, you need a heating system that’s ready. If your heater is short-cycling, the burner flame keeps going out, or you have no heat after a Chinook night, we’ll diagnose the problem and provide heating repairs that get warm air moving again. We provide furnace repairs, maintenance, and installations that are built for mid-March snowstorms and 80 mph wind gusts.
Boiler Services for Boulder Homes
Many Boulder homes near downtown or University Hill still rely on boilers with radiators or baseboard heat to stay warm. Our technicians provide boiler repairs, maintenance, and replacement, so you have consistent heat and hot water when temperatures drop below freezing. We service all makes and models, including modern high-efficiency condensing units and cast-iron boilers, so you get even, quiet heat through the coldest weeks of the year.
Professional Plumbing Repair and Water Heater Services
Our Boulder plumbers keep your kitchen, bathroom, laundry room, and basement plumbing flowing freely with professional plumbing and water heater services. With a climate that swings every day and water heaters tucked into unheated garages, it’s not uncommon to run into burst pipes or flooded basements.
Count on us for the following plumbing services:
- Water heater repair and replacement
- Tankless water heater services
- Drain cleaning
- Leak detection
- Sewer line repair
- Sump pump services
Garage Door Repair and Service in Boulder
Our garage door repairs cover your entire system, including the springs, openers, cables, tracks, and panels that need to work when you leave for the Flatiron Flyer every morning. We handle repairs when hail season dents panels and bends tracks, replace worn rollers and weatherstripping when the UV dries them out, and upgrade your entire system when it reaches the end of its lifespan.
HVAC Solutions for Older and Newer Boulder Homes
Homes in Boulder range from Whittier Victorians built in the early 1900s to new construction in Gunbarrel, and their HVAC systems don’t respond to a one-size-fits-all approach. Our HVAC services in Boulder are designed to fit your home, so you get solutions built for your floor plan.
We begin every HVAC service with a thorough assessment, checking your ductwork, insulation, and existing setup to find the right fit for your home. We size equipment to your square footage and elevation, adjust duct runs and returns if needed, and recommend zoning or mini-splits if a single system can’t cover an addition or converted space.
Preventative Maintenance for Year-Round Home Comfort
Boulder’s seasons mean many homeowners fire up their heating and cooling systems the same week, and most find out about problems at the same time. Scheduling preventative maintenance with our team catches hidden problems before you start up your system for the season. Our technicians check key components, clean indoor and outdoor units, inspect for proper operation, and verify safety controls so your system is ready to go when the first freeze or summer heat wave arrives.
Our Peak Advantage Service Agreement includes seasonal maintenance visits, priority scheduling, and preferred repair rates. You’ll get a furnace tune-up in the fall, and a cooling system check before summer arrives, plus a front-of-the-line spot when something goes wrong.
