Tim Doerr Heating & Cooling - Evansville's Professional HVAC Services

This is often a sign of a faulty reversing valve, a common issue with our local heat pump systems. This critical component switches your system between heating and cooling modes. When it gets stuck, your home won't heat properly. Our technicians are experts in diagnosing and repairing reversing valve issues. We'll perform a precise diagnostic to confirm the problem and provide a clear, upfront repair plan to restore efficient, warm airflow to your Evansville home.

Given our local humidity and allergen levels, a multi-layered approach works best. We recommend starting with a high-efficiency air filter (like a MERV 13) to capture particles, and often pair it with a whole-home air purifier, such as a UV-C light system, to neutralize mold spores, bacteria, and viruses. For homes with excessive dryness in winter or humidity in summer, adding a humidifier or dehumidifier can drastically improve comfort and health. We'll assess your home's specific needs and recommend a tailored solution.

We strongly recommend biannual maintenance—once in the spring for your cooling system and once in the fall for your heating system. Our intense seasonal shifts put extra strain on components. This proactive service allows us to clean critical parts, check refrigerant levels, ensure electrical connections are tight, and catch small issues—like early signs of reversing valve wear—before they lead to a costly breakdown and leave you without comfort during a heatwave or cold snap.
