It is normal to have problems with your air conditioner every once in a while. But while some issues can wait, others may require immediate treatment. Failing to do so might result in major damage, so don’t wait until an emergency AC repair is necessary. Call your HVAC technician as soon as possible if you notice signs such as:
1. Lack of Cold Air
Delivering cold air is the main job of an air conditioner. If your thermostat is working correctly yet your AC is not performing as expected, there must be something wrong with the system. It could be a faulty compressor or a lack of refrigerant. Either way, keeping your AC running like this will only put more strain on the system, which may result in a much higher electric bill and a shorter lifespan for your AC unit.
2. Breaker Trips
Not only can these damage your AC unit, but electrical issues can also cause a fire hazard. Do not underestimate any problems with your electrical system, especially if you find a breaker trip. What you need to do in this situation is to power off your house and get a certified electrical technician to come as soon as possible. Fixing a breaker trip is not a DIY job, although it may look like an easy thing to do.
3. Strange Noise
Some AC units normally make humming sounds in the background, which is fine. But if you hear an unusual noise coming from your air conditioner, you need to find out where it’s coming from. Noises like gurgling, banging, or squealing might indicate that some components are breaking apart or letting loose. Choosing to ignore it might cause serious damage, such as a permanently broken compressor. If this happens, then you will have to replace the whole unit in the end.
4. Ice on the Evaporator Coils
Although they are meant to cool down the air, evaporator coils are not supposed to have ice on them. If such a thing happens, turn off the system and clean up the water that drips on the floor. It might be refrigerant leaking, dirt buildup, or faulty coils. Get your HVAC handyman to inspect the issue and fix it before you turn your AC unit on again. Forcing your AC to keep running despite the ice will put it at risk of overheating, while the dripping ice might cause mold growth or damage your home’s interior.
5. Foul Smell
If you smell something like burnt plastic, there might be a dangerous electrical fault going on. Turn off your system completely to prevent a fire hazard or short circuit. Do not turn it back on until an electrical technician fixes the issues. Another possible explanation of a foul smell from your AC unit is probably a mold growth in the ductwork, which also requires immediate treatment.
An emergency AC repair can be costly and inconvenient. Fortunately, you can minimize the risk with regular maintenance on your AC unit. Experts recommend a system tune-up and general checkup at least twice a year. Make sure you don’t miss it.
