When you need a reliable heating company in Evergreen, CO, Sanders & Johnson brings nearly 50 years of expertise to your mountain home. Our family-owned business specializes in the complex heating challenges that come with Colorado’s harsh winters, from aging furnace systems struggling on sub-zero mornings to boiler repairs that require genuine technical expertise.

That’s why we’ve built our reputation on HVAC solutions that actually fix the problem rather than just selling you new equipment.

Comprehensive Heating Services

Trusted Heating Contractors in Evergreen, CO

Many homes here feature a mix of older cabins, custom A-frames, and mountain properties with heating systems that require specialized knowledge. Sanders & Johnson tackles these complexities head-on with engineering-level analysis and technicians who understand both modern systems and aging equipment.

Our approach to heating repair starts with genuine diagnostics. Our trained technicians investigate the root cause of your heating issues, whether that's a furnace that won't fire on cold mornings, ductwork problems from decades-old installations, or boiler complications that most companies can't even identify. This technical depth is what sets us apart in the Denver foothills.

When we recommend a new heating installation or replacement, it's because we've done the analysis to prove it's your best option.

Furnace Repair in Evergreen, CO

Your furnace works harder in Evergreen than it would almost anywhere else in the country. Long winters, frequent temperature swings, and high-altitude conditions put serious stress on heating equipment. When furnace problems strike, you need technicians who can diagnose and fix issues quickly, especially during those cold snaps when your family depends on reliable heat.

Common furnace problems we handle include: 

  • Systems that cycle on and off repeatedly
  • Furnaces that blow cold air
  • Strange noises from the blower motor
  • Complete heating failures

We service all major furnace brands and models, including systems in older mountain homes that other companies refuse to touch. Whether you're dealing with a gas furnace that won't ignite or an electric system with heating element failures, we bring the technical capability to get your home warm again.

Heat Pump and Furnace Installation in Evergreen, CO

Installing a new furnace or heat pump in an Evergreen mountain home requires more than basic HVAC knowledge. At over 7,000 feet elevation, our region’s high altitude impacts equipment sizing and gas appliance performance in ways most homeowners never consider. 

Insulation characteristics, ductwork configuration, and specific heating load all factor into selecting the right furnace installation for your Evergreen home. An oversized furnace cycles too frequently and wastes energy. An undersized system can't keep up during the coldest weeks. We get it right the first time.

We handle all necessary permitting and ensure every installation meets Jefferson County code and Colorado energy efficiency standards. When you're ready to upgrade, our team can also help you take advantage of Colorado energy rebates and our flexible financing options to make the investment more manageable.

Boiler Repair and Service in Evergreen

Here's something most HVAC companies won't tell you: genuine boiler expertise is rare. Yet about half of homes in the western Denver metro area rely on boiler systems for heating. Sanders & Johnson is one of the few companies in Colorado with true boiler specialists who understand the complexity of these systems.

Boilers require different diagnostic skills than forced-air furnaces. When you call us for boiler repair, you're getting technicians trained to handle hydronic heating systems and radiant floor heating. We diagnose and repair common boiler problems like pressure issues, circulator pump failures, leaking pipes, and strange noises that indicate scaling or air in the lines.

When you've got a boiler problem, you can't afford to work with a company that's just guessing. Our approach to boiler repair in Evergreen combines diagnostic tools, technical training, and decades of experience with these systems. That expertise means faster repairs, accurate solutions, and heating systems that keep working through the harshest winter conditions.

Seasonal HVAC Maintenance

Regular preventative maintenance catches small problems before they escalate into expensive emergency repairs. The last thing you want to deal with is a furnace or boiler that fails during a multi-day cold spell. 

Our maintenance programs focus on the inspections and adjustments that actually matter. We're not checking boxes on a generic list. Instead, our technicians perform the specific heating service tasks that prevent failures and maintain efficiency in mountain conditions.

Heating maintenance checklist

During a comprehensive heating system inspection, Sanders & Johnson technicians perform detailed checks on all components that affect performance and safety.

  • Examine heat exchangers for cracks or corrosion
  • Test ignition systems and flame sensors
  • Inspect and clean burners
  • Verify proper airflow and vent operation
  • Test all safety controls
  • Check water pressure and temperature settings
  • Inspect circulator pumps and zone valves
  • Lubricate moving parts where applicable
  • Test thermostat operation to verify your system responds properly
