Applied Building Technologies | Local HVAC Repair in Baltimore, MD

Yes, a faulty reversing valve is a common culprit for this issue, especially in Baltimore homes where heat pumps work hard year-round. This valve is essential for changing the flow of refrigerant to provide either heating or cooling. Our technicians can diagnose valve problems—like electrical failure or mechanical sticking—and perform the precise repair or replacement needed to restore your system's proper function.

This frustrating problem can have several causes, from refrigerant leaks and dirty coils to a failing compressor or a clogged condensate drain. The intense summer humidity in our area puts extra strain on AC systems. We'll perform a comprehensive diagnostic to pinpoint the exact issue—whether it's a simple fix like cleaning or a more complex component repair—to get your cool air flowing again quickly and efficiently.

First, check your home's circuit breaker panel to ensure the system hasn't tripped a switch. Next, check or replace the air filter, as a severely clogged filter can cause the system to shut down. If these simple steps don't resolve it, turn the system off and call us. Continuing to run a malfunctioning system, especially during our extreme temperatures, can cause further damage. Our team offers prompt service to diagnose and safely repair the problem.
