HVAC Services Frederick MD | Call Air and Vac Services

Yes, that's a common issue we see in Frederick. The reversing valve switches your heat pump between heating and cooling modes. When it fails or gets stuck, it can cause the exact problem you're describing. Our technicians are experts at diagnosing and repairing or replacing faulty reversing valves to restore proper heating to your home quickly.

High humidity is a frequent challenge in our area that can overwhelm standard AC systems. When humidity is too high, your system works harder, leading to reduced efficiency, higher bills, and that sticky feeling. We can assess your system's capacity and dehumidification performance, offering solutions like system adjustments, maintenance, or recommendations for enhanced dehumidification to make your home truly comfortable.

Proactive, seasonal maintenance is key. For Frederick homes, our maintenance checks include inspecting the heat pump's reversing valve operation, cleaning coils for optimal efficiency, checking refrigerant levels, and ensuring the condensate drain is clear to handle our humid climate. This regular care helps prevent valve failures, improves dehumidification, and extends your system's lifespan, saving you money on repairs and energy costs.
