Keystone Htg & AC Co - Racine's Reliable HVAC Services

Uneven heating is a common issue in older Racine homes, often due to ductwork problems, an improperly sized furnace, or air balancing issues. Our experienced technicians start with a thorough inspection of your entire HVAC system. We check for leaks or blockages in your ducts, assess your furnace's capacity, and ensure your system is properly balanced for your home's layout. Based on our findings, we provide clear recommendations, which could range from duct sealing and repairs to a system adjustment or, if needed, discussing a correctly sized replacement unit. Our goal is to deliver consistent, comfortable warmth to every room.

Our preventative maintenance service is designed to keep your system running efficiently and reliably through Racine's harsh winters and humid summers. A typical visit includes cleaning critical components like the condensate drain—a common source of clogs—checking refrigerant levels, inspecting electrical connections, testing safety controls, and lubricating moving parts. For furnaces, we perform combustion analysis and heat exchanger inspections. This proactive care helps prevent unexpected breakdowns, improves energy efficiency to manage utility costs, extends the life of your equipment, and maintains healthy indoor air quality for your family.

While we are proud certified Lennox dealers and often recommend their high-efficiency products, our expertise extends far beyond a single brand. Our technicians are trained to service, repair, and maintain all major HVAC makes and models, including Rheem and Bryant. For repairs, we have the parts and knowledge to fix your existing system. If you're considering a replacement, we provide honest comparisons and options that fit your home and budget. Our primary commitment is to the right solution for your Racine home, backed by our experienced installation and service teams.
