How do you know when you need an air conditioner repair? Picture this: it’s a sweltering day in mid-July, you’ve just gone for a three-mile run, have sweat out about a gallon of bodily fluid, and are now looking forward to the sweet reward of a tall glass of ice water and the glorious sensation of cool air blasting your face from your air conditioner.
But instead, you open your door and are greeted with a backdraft of horrifying heat. Your runner’s high quickly transforms into a runner’s low – your A/C unit is broken.
We’ve painted a pretty terrible scenario, but the good news is, it doesn’t have to be like this. When you know the warning signs of a disgruntled HVAC unit, this entire situation is completely preventable. Here are 10 tell-tale signs that your air conditioner needs maintenance.
1. Lack of Air Flow
This one’s pretty obvious. If there is a weak flow, or no air at all coming from your unit, you have a problem. This usually means there’s a malfunction with the compressor or the air ducts, and you should call for service pronto.
2. Blowing Warm Air
Warm air is nice in December but it’s not exactly ideal in the summer months. This usually indicates that you could be low on refrigerant or have a problem with the compressor. Your ducts could also be bringing in warm air from outside, which needs to be addressed.
3. Air Conditioner Thermostat Isn’t Working
Your thermostat is your control center and without it, everything goes haywire. It tells the rest of the unit what to do and when to do it. If it won’t turn on or shuts on and off without rhyme or reason, that usually means it needs to be replaced.
4. Your Utility Bill Skyrocketed
If you notice an unusually high utility bill it could be a sign that your A/C unit has lost its efficiency. There could be several reasons for this, but it usually means that your unit might be near the end of its life. Be sure to find an expert or other qualified professionals in your area.
5. The Unit Is Behaving Erratically
If your unit turns on or off for short periods or at strange times it usually means you need an air conditioner repair. You should be relatively used to the cycles, and if you notice a wild deviation from the norm, it’s time to call an expert.
6. Moisture Buildup or Leakage Near the Unit
A little bit of moisture can often just be condensation but if you notice a build-up, it’s time for immediate air conditioner help. The culprit could be a refrigerant leak, which is poisonous and could potentially be dangerous.
7. Strange or Foul Smells
An unusual or putrid smell coming from your unit needs to be addressed right away. This could be a leak or something worse, and not something you want to take chances with.
8. Loud or Strange Noises
If your air conditioner suddenly starts to make unfamiliar sounds it usually means it needs maintenance. A rattling-type sound could mean a loose part and something that an HVAC professional should easily be able to identify.
9. Your Home Feels Overly Humid
Your air conditioner’s job is to moderate humidity levels in your house. If you suddenly feel like you’re living in a sauna, it’s time to call for help.
10. The Lifespan of the Unit Has Run Its Course
Your air conditioner has a typical lifespan of about a decade. If you start noticing warning signs around this time, it’s a good idea to start shopping around for a new unit.
