Krebs Karl Refrigeration & Air Conditioning | Reliable HVAC Services in Parkville, MD

Yes, that's a common sign of a refrigerant leak, especially in our area. A low refrigerant charge forces your system to work much harder to cool, increasing wear and energy costs. Our technicians use advanced electronic detectors to find even the smallest leaks. We then repair the leak, perform a pressure test, and recharge the system to the manufacturer's exact specifications, ensuring efficient and reliable cooling for your home.

A faulty reversing valve, a frequent issue here, can cause your heat pump to get 'stuck' in one mode. You might notice it blowing cool air when set to heat, or warm air when set to cool. It may also make a distinct hissing noise. We diagnose valve issues by checking system pressures and operation. Often, the valve can be repaired, but if replacement is needed, we ensure it's done correctly so your system can seamlessly switch between heating and cooling as needed.

Promptly. Ignoring these issues can lead to compressor failure—the most expensive part of your system to replace. A leak forces the compressor to overwork, while a stuck valve creates improper pressures. We recommend scheduling a diagnostic visit as soon as you notice a change in performance. Our local team offers timely service to protect your investment and prevent a minor repair from turning into a major system replacement.
