HVAC Services in Golden, CO

Our HVAC services in Golden cover repairs, installation, maintenance, and indoor air quality for furnaces, ACs, heat pumps, boilers, and ductless systems. We service all major makes and models, including Carrier, Trane, Lennox, Rheem, and more, providing solutions that help your equipment keep up with the Colorado climate.

Furnace repair and installation

Our furnace repair and installation in Golden keeps your home warm when Arctic air blows across the Front Range. If your furnace is short cycling, blowing lukewarm air, or tripping its limit switch, our technicians diagnose the problem and provide the solution that your home actually needs. If furnace replacement becomes the best option, we size the new unit to your home and make sure it’s designed to handle Colorado winters. 

AC repair and installation

When summer highs climb and the sun shines down on South Table Mountain, our AC repair and installation in Golden keeps your home cool through it all. Our NATE-certified technicians repair existing air conditioning systems and install HVAC replacements for Golden homes. We also offer thermostat services and flexible financing options for cooling installations.

Heat pump services

We provide a full range of heat pump repair, installation, and replacement in Golden. Many Colorado homeowners are incorporating heat pumps to cool in the summer and add heat in the early days of winter. We can help you decide whether these two-in-one systems are right for your home, pair them with your existing heating system, and walk you through your rebate options.

Boiler services

At Sanders & Johnson, we’re your local boiler experts. Roughly half the homes in Colorado’s foothills are heated with boilers, especially older homes around Golden’s historic downtown. We provide boiler repairs, maintenance, and installation for gas-fired systems, including high-efficiency Lochinvar models, standard-efficiency Weil-McLain units, and Laars equipment. 

Ductless mini splits

We install and service ductless mini-splits to heat and cool spaces where ductwork can’t reach. Whether you have a finished basement, lower walkout onto the hillside, or a converted garage, we install Mitsubishi and Daikin ductless systems and size each head to the room, so you get even comfort without wasted energy.

Indoor air quality solutions

Our indoor air quality solutions help your family breathe easy when the dry air and wildfire smoke settle into the valley. We install whole-home humidifiers to keep winter humidity comfortable, media and HEPA filtration to capture smoke and dust, and UV lights to keep your coils and air handlers clean. 

Benefits of HVAC Maintenance in Golden, CO

Routine HVAC maintenance in Golden helps prevent breakdowns on the hottest or coldest night of the year. With Golden’s dust, cottonwood seed, and swinging temperatures, your heating and cooling equipment is constantly put to the test. Regular furnace and AC tune-ups help protect your systems by:

• Catching minor problems early so you don’t have to call for same-day repairs during peak season.
• Boosting efficiency to use less gas and electricity and lower your utility bills.
• Extending the lifespan of your equipment. 
• Keeping your manufacturer warranty valid for the full coverage term.

Plumbing Services in Golden, CO

Our plumbing services in Golden keep your kitchens, bathrooms, and main lines protected. When the hard Clear Creek water, expansive clay soils, and decades-old housing stock cause problems with your fixtures, pipes, or appliances, we diagnose the root cause and fix it right the first time.

Drain cleaning

We provide drain cleaning services that clear clogs caused by mineral scale, grease, and root intrusion. We use drain cameras to locate the root cause, then use hydro jetting or cabling to clear it based on what we find.

Sewer line repair and replacement

When your main lines crack, belly, or fill with roots, our team performs sewer line repairs and replacements that stop backups for good. We camera-inspect every line before recommending work and offer trenchless solutions when conditions allow to protect your yard and driveway. 

Gas line services

Our gas line services in Golden include leak detection, repair, and new installation for furnaces, boilers, water heaters, ranges, and outdoor appliances. If you smell gas inside your home, leave immediately and call 911. Once emergency services clear the area, contact our team to repair the line and restore service safely.

Piping and repiping

We provide piping and repiping in Golden to fix low pressure, rusty water, and pinhole leaks that come from aging galvanized or copper plumbing. Many older homes still have their original supply lines that have been scaling for decades. We repipe with PEX or copper and work room by room to keep your home livable during the process.

Water line repair and replacement

When shifting soil, freezing winters, or aging pipes cause your main supply line to break, we restore flow with water line repair and replacement in Golden. If you notice a sudden drop in pressure, a wet patch in your yard, or an unexplained jump in your water bill, give us a call. 

Sump pump services

Our sump pump services in Golden protect your basement when the spring snowmelt and afternoon storms send runoff down from the foothills. We install, repair, and replace sump pumps and battery backup systems to keep your pump running through power outages and winter storms.
