Certified HVAC Services in Billings, MT 59105 - Wallis Mechanical Heating & Cooling Division

Short cycling is a common issue here, often caused by an oversized furnace, a dirty air filter, or a faulty flame sensor. It wastes energy and strains the system. Our technicians can diagnose the exact cause, whether it's a simple cleaning or a component repair, to restore normal operation and improve your furnace's efficiency and lifespan.

If your AC is blowing warm air or you see ice on the coils, you may have a leak. Refrigerant is essential for cooling, and low levels force the system to work harder. Don't just add refrigerant—the leak must be found and sealed. We'll perform a leak detection test, repair it, and recharge the system to proper levels, ensuring efficient cooling for our Montana summers.

Regular maintenance is key to preventing the common problems we see, like short cycling and leaks. Our seasonal tune-ups include cleaning critical components, checking refrigerant levels, and testing safety controls. This proactive care improves efficiency, lowers utility bills, extends your system's life, and helps avoid unexpected breakdowns during our extreme hot and cold seasons.
