Monthie Heating & Air Conditioning - Lexington's Certified HVAC Repair

This is a common issue often caused by a faulty reversing valve, a key component in your heat pump system. When this valve malfunctions, it can't properly redirect refrigerant flow to change modes. Our technicians are experienced in diagnosing this precise problem common in our climate. We'll perform a thorough inspection to confirm the issue and provide a clear repair or replacement plan to restore your system's full functionality.

Older homes in our area can accumulate dust, allergens, and humidity. We recommend starting with a professional HVAC inspection and duct cleaning to remove existing contaminants. From there, we can install solutions like high-efficiency air filters, UV light air purifiers to neutralize microbes, or whole-home dehumidifiers to control moisture—all tailored to your specific home and family's needs for healthier, cleaner air.

Signs needing immediate attention include strange noises (like grinding or banging), a complete loss of heating or cooling, frozen coils, or a burning smell. Issues like uneven temperatures or a gradual increase in bills often point to needed maintenance. As your local HVAC experts, we recommend annual tune-ups to prevent emergencies. If you're experiencing any urgent symptoms, call us right away for prompt, same-day service to prevent further damage to your Lexington home's system.
