Guy Edgar's Heating and Air Conditioning | Experienced HVAC Services in Cambridge, MD

This is a common issue during our hot, humid summers. The cause could range from a refrigerant leak and a frozen evaporator coil to a failing compressor or a clogged air filter. Our technicians will perform a thorough diagnostic to pinpoint the exact problem, whether it's a simple fix or a more complex repair, and get your cool air flowing again quickly.

A faulty reversing valve, which switches your system between heating and cooling modes, often shows itself when your heat pump is stuck in one mode, provides inadequate heating, or makes a distinctive hissing noise. This is a critical component, especially during our variable Eastern Shore seasons. We can accurately diagnose valve issues and perform the precise repair to restore your system's full functionality for year-round comfort.

First, check your thermostat settings and circuit breaker. If those are fine, give us a call immediately. We prioritize emergency calls for our neighbors, especially during extreme weather. Our team will work to get to you as fast as possible to diagnose the issue—whether it's a full system failure or a critical component like a compressor—and implement a repair to secure your home's comfort and safety.
