The weather is starting to warm up here in central Alabama, and whether it stays that way or gets frigid again, you may have already turned on your AC for the first time this year… or tried to turn it on. What happens if it doesn’t turn on? That’s what we’re discussing today. There are a few basic things you can test or change before resorting to calling your HVAC repair experts at Autumn Air in Pelham, AL. So here’s what you should check:
1. The Basics
“Have you tried turning it off and back on again?” We’re not recommending you do that with your HVAC unit, but rather reminding you to remember to check the basic, so-simple-you-forgot-to-try-it factors that might be causing the problem.
First, check the circuit breaker to see if an electrical problem is causing the issue. Make sure everything is plugged in properly as well.
If that’s not it, you should also check your thermostat. Sometimes the thermostat is actually the culprit, and the AC unit may be totally fine. Make sure your thermostat is fully connected to a power source and is in cool mode. Again, while these may sound like fairly basic tips, they can be easy things to check out when your AC isn’t turning on.
2. The Filter
Replacing your AC filters on a regular basis is a simple but very important maintenance task. Your filters play a crucial role in your overall HVAC system, preventing dust and debris buildup from causing problems. This buildup forces your AC to use more energy to keep your home cool, which can result in higher-than-normal utility bills. If you don’t address the issue, it can also cause your AC to stop working entirely. Replacing your filters before they get clogged will not only prevent breakdowns, but can also extend the lifespan of your AC system.
After checking the basics, check your filter to see if it needs to be replaced. Forcing your AC to use excessive energy to cool your home puts the system through substantial wear and tear and may be the reason your unit didn’t turn on. This is something you will not need to worry about if you do change the filters often!
3. The Evaporator Coils
Keeping your evaporator coils clean is another important maintenance task. At this point you may be thinking (or even saying aloud), “ok this is starting to be a little too much…I do know how to clean evaporator coils or even where they are!” Understandable. This is something that our HVAC technicians can address when we come out for a diagnostic visit, but can be done on your own if you know how. Like changing your filters regularly, cleaning your evaporator coils will reduce the odds of your air conditioner not working. Check them if the AC isn’t turning on. If they’re dirty, there’s a good chance that’s the reason you have a problem.
4. The Drain Pan
Sometimes the drain pan, located under the indoor section of your AC unit, becomes full. When this happens, it might trigger a float switch, which will keep your AC from turning on. Our experts will help you understand what steps you can take to reduce the chances of this happening. Next time we are at your home for routine maintenance or for HVAC problems, we will gladly show you how to check your AC’s drain pan.
Extra Bonus: Learn to do a Capacitor Test
Ready to add “knows how to conduct a capacitor test” to your list of skills?
This can help you if your AC did come on and then made strange or new noises before it quit. It may be a sign that the motor has failed. A capacitor test will let you know whether this is the case. With that being said, if you notice your air conditioner making strange sounds, it’s best to go ahead and schedule an HVAC repair service with Autumn Air in Pelham, AL. Unexplained or unexpected noises are almost always linked to some sort of AC problem.
Remember that preventative maintenance is the best thing you can do for your HVAC system, since we’re able to detect, clean, inspect, and repair all in one visit. Additionally, doing this will help your system stay efficient and subsequently save you money on energy bills. Now is the perfect time for a tuneup before Spring arrives.
