Signs You Need an AC Contractor in Baltimore County

A central air conditioning system is a complex machine, and it’s difficult to know when an odd sound or strange smell needs professional help. Here are the most common AC problems that require an expert.

Low Refrigerant: Refrigerant is the magic that makes your air conditioner work by pulling heat out. If your refrigerant level is low or there’s a leak, it can cause coils to freeze, and ultimately, your house won’t get as cool as you want.

Odd Sounds: An air conditioner should run nearly silently, so when you hear strange noises like banging, squealing, or grinding, shut it off and call an expert to diagnose the problem.

Clogged Condensate Drain Line: The air conditioner removes humidity aside from cooling your home. That moisture must be properly drained outside the house. Over time, algae and debris can clog the drain line, causing water leaks, which could lead to mold and water damage.

Continuous Running or Short Cycling: The air conditioner should undergo a normal on/off cycle. If it turns on and off rapidly or runs continuously, it signals a problem. Continuous Running or Short Cycling: The air conditioner should undergo a normal on/off cycle. If it turns on and off rapidly or runs continuously, it signals a problem. Constant running and short cycling cause excess wear and tear and could lead to premature system failure.

Electrical Issues: Call an HVAC contractor immediately if your lights flicker or dim or the breakers trip when your AC powers up.
