Having HVAC Problems? We’ll Fix Them!
Our licensed technicians handle every aspect of residential and commercial HVAC care, including system installation, troubleshooting, and maintenance. Every project is approached with technical accuracy and clear communication. No upsells. No delays.
HVAC Installation Thornton, CO, Home and Business Owners Can Trust
Replacing your heating or cooling system isn’t just about swapping out equipment. It requires proper sizing, airflow planning, and load calculations. We use Manual J standards as a part of our commercial and residential HVAC installation services to ensure your system is matched to the insulation levels, window exposures, and square footage of the space. An oversized or undersized unit creates inefficiencies and shortens system lifespan, and our process avoids that.
We install high-efficiency units from trusted manufacturers and include a 100% satisfaction guarantee on every job. Our team walks you through your equipment options and pricing before any work begins.

AC Repair and Maintenance
If your AC stops working, our team is ready to respond. We provide AC repair in Thornton without after-hours fees during our standard schedule (7:30 am to 6:00 pm) and offer emergency service as needed. You’ll receive a flat diagnostic rate, and we don’t begin repairs without your approval.
Our technicians arrive in fully stocked trucks, allowing us to resolve most problems in a single visit. We work on all major makes and models and back each repair with our full satisfaction guarantee.

Fast, Reliable Furnace Installation and Repair
If your furnace is underperforming, constantly breaking down, or approaching the end of its lifespan, we can help you replace it with a high-efficiency model that heats your home reliably while cutting energy costs. We take into account your ductwork, square footage, and airflow needs to recommend the right equipment.
We also repair existing furnaces and resolve most issues on the first visit. Whether it’s a faulty ignitor, worn blower motor, or dirty sensor, we’ll identify the problem, explain your options, and complete the repair with quality parts.

Hybrid Systems
A hybrid system uses both a heat pump and a gas furnace to heat your home efficiently. The system switches between the two based on outside temperatures—using the heat pump when it makes sense and the furnace when more heating power is needed.
We install hybrid systems in Thornton homes where homeowners want to cut energy use without giving up cold-weather performance. Every installation starts with a proper heat loss calculation to make sure the system fits the space and performs the way it should.
If you’re not sure if a hybrid setup is right for your home, we’ll explain the pros, the costs, and what to expect before you move forward.
