HVAC Repair Baltimore MD | Call All Things Air & ice

Yes, a faulty reversing valve is a common culprit when a heat pump blows cold air in heating mode, especially with the frequent cycling our Baltimore systems undergo. Our technicians perform a thorough diagnostic to confirm the valve is the issue. We then expertly replace the valve, ensuring proper refrigerant flow and restoring your system's ability to switch between heating and cooling efficiently for our local climate.

In Baltimore's humid environment, corrosion on your condenser is more than cosmetic—it's a threat to your system's longevity and efficiency. Rust can weaken the cabinet, damage internal coils, and lead to refrigerant leaks. We recommend a professional inspection. We can treat existing corrosion to prevent spread and apply protective coatings to shield the unit from future moisture and salt air, a common issue for homes near the Chesapeake.

We recommend a bi-annual maintenance plan tailored to our local weather. In spring, we focus on the cooling system, cleaning the condenser coils to prevent corrosion buildup and checking refrigerant levels. In fall, we service the heating components, inspecting the heat pump's reversing valve operation and electrical connections. This proactive, local-focused care helps catch small issues like early-stage corrosion or valve wear before they lead to a costly breakdown during a Baltimore heatwave or cold snap.
