Furnace Installation
Our furnace installation service ensures reliable heating for Denver homes and businesses. Using high-efficiency Carrier systems, we customize installations to match your property's size and climate needs. Technicians prioritize proper sizing and ductwork optimization to maximize energy savings. With rebates up to $2,600, we deliver cost-effective solutions that maintain comfort during Colorado's harsh winters while reducing long-term energy costs through improved SEER ratings.
Geothermal Systems
We specialize in geothermal heating and cooling solutions that leverage underground temperatures for year-round efficiency. Our design/build team creates closed-loop systems tailored to property specifications, offering 50-70% energy savings over traditional HVAC. Services include site assessment, horizontal/vertical loop installation, and integration with existing infrastructure. Nationwide capabilities support residential, commercial, and industrial applications, with federal tax credits available to offset initial investment costs.
Commercial HVAC
Our commercial HVAC division handles complex systems for facilities ranging from retail spaces to hospitals. Services include VRF installation, building automation programming, and chiller maintenance. Preventive maintenance agreements feature predictive diagnostics to avoid downtime. We specialize in retrofitting legacy systems with smart controls while ensuring compliance with ASHRAE standards. Emergency service teams carry OEM parts for 90% of commercial equipment brands to minimize repair times.
Air Quality Solutions
We improve indoor air quality through hospital-grade GPS technology that neutralizes 99.4% of pathogens, including SARS-CoV-2. Solutions include HEPA filtration systems, UV light purifiers, and humidity control. Commercial installations meet CDC guidelines for healthcare facilities. Residential packages integrate with existing HVAC to reduce allergens and VOCs. All solutions maintain proper ventilation rates per ASHRAE 62.1 standards while optimizing energy efficiency through demand-controlled ventilation.

Report
Treavor my technician was very professional and saved me money by replacing the primer motor instead of selling me a new furnace. This way I'll get a couple more years out of my furnace and when the time comes they will get my business for a new furnace. Thank you Major Heating & Air!

Lady said she would have her scheduling people call me back about getting an estimate done. Nobody ever bothered to call back.

Report
Very poor customer service and left me high and dry. Heat in my residence wouldn't work so paid Major $90 for a tech visit. Diagnosis was that I needed a new custom retrofit thermostat at around $1100, so I wanted to submit the repair as a claim to my home systems warranty. Major's office staff initially said they'd gladly prepare a detailed estimate and wrote a brief letter I could submit to my warranty provider. However, after numerous phone calls and several empty promises by office staff over three weeks, they failed to perform.
As a result, my warranty claim was cancelled and will likely be denied as a pre-exiating co edition if I try to resubmit it later on. Thernostat still not fixed. Numerous other reviews share similar stories of Major leaving them hanging; do yourself a favor and look elsewhere.

They were able to get to our house within an hour of calling after trying many other heating companies who didn't answer, did poor work at our house previously, didn't call back, etc. I highly recommend them and will definitely use them again in the future! Service: Heating system repair
