With global temperatures reaching higher levels than ever, air conditioning is becoming a staple in areas where it may not have been before. More people relying heavily on air conditioning also means more risks for HVAC emergencies that can prove costly and disruptive. Here are a few of the most common emergent issues with HVAC systems and some tips to help you respond to those problems.

Total System Failure

When your HVAC system stops responding altogether, it could be a result of a refrigerant leak, compressor failure, or even something as simple as a blown fuse. Start by checking the thermostat to be sure that it is calling for cooling services. If it is, then check the circuit breakers. Reset the breaker if possible to see if that restores operation. If the unit shuts down due to a thermal overload or similar complication, resetting the breaker might restore function. Otherwise, call an emergency repair technician right away to isolate the source of the problem.

Water Leaks

If you have a leak from your HVAC system, you need to be mindful of the problems that could indicate. In most cases, air conditioning systems drain a small amount through the condensate drain as they operate. When your unit is leaking, that means the drain isn't flowing as it should. This is often a simple problem, such as a blockage in the drain line. Flush the drain line, and it could restore proper drainage. If not, shut the system down and call for emergency repairs.

Odd Noises

Air conditioning systems make some noise, but they shouldn't be obtrusive, and those noises shouldn't change markedly over time. If you start to notice unusual sounds, including any rattling, squealing, or whining, those are signs of potential problems with the motor, bearings, or fan. You should call for an emergency repair technician as soon as you hear sounds like this and shut the system down until they arrive to reduce the risk of catastrophic damage.

The more you understand about common issues with HVAC systems, the easier it is to respond when the AC fails or malfunctions. Emergency repairs can help you get your home's climate control system back to its best as soon as possible, which is important with heat waves and unpredictable summer temperatures. Watch for these types of complications, assess the situation carefully, and try mitigating steps when it is safe to do so. Then, call an emergency HVAC repair technician for more help.
