Hello, fellow DIY enthusiasts! It's your friendly neighbourhood repairman, here to sweat it out in your stead, sharing my top blend of experience and expertise. Let's dive into our topic for today.
Is Your AC Always Running? Let's Fix it!
Okay, picture this: It's a sweltering summer day, your air conditioner seems to be on its own marathon, running constantly, and you're thinking: why won't it take a chill pill? Hey, I feel you! That's why I'm dashing in to save the day, toolbox in hand, ready to help you fix your overzealous AC.
First Things First: Some Detective Work
Before we start tinkering, we need to find out why your AC has become an overexcited hamster on a wheel. Here are some initial questions to ask yourself:
- Is the air coming out of the vents cool?
- Is the AC able to maintain your desired temperature?
- Does it seem like your electricity bill is higher than usual?
If you answered 'no' to the first two questions and 'yes' to the last one, we've got a problem. Your AC is working overtime and something is causing this inefficiency. Let's figure out what that could be.
Common Culprits Behind a Constantly Running AC
The phrase 'too much of a good thing' definitely applies to an air conditioner that won't stop running! Here are some of the usual suspects:
A Dirty or Clogged Air Filter
A dirty air filter is one of the most common reasons behind an overactive AC. It blocks air flow, causing your AC to work harder to cool your house. Luckily, it's also one of the easiest things to fix: simply replace the filter regularly (usually, every 30-60 days, but check your manufacturer's guidelines).
Incorrect Thermostat Settings
Check your thermostat settings! If your thermostat is set to 'ON', it means your AC’s fan will continuously blow air, cold or hot, into your home. Instead, set it to 'AUTO', so the fan only blows when your AC is cooling the air.
Low Refrigerant Levels
Your AC uses refrigerant to cool the air inside your house. If the refrigerant level drops, due to a leak, your air conditioner will struggle to cool the air, and will run continuously. It's a bit of a complicated issue to diagnose and fix, and may require a pro's help.
Poorly Sized Air Conditioner
Like Goldilocks, air conditioners need to be just the right size! If an AC is too big, it will constantly cycle on and off (short-cycling), and if it's too small, it will run continuously. You might need professional guidance to determine the correct size for your home.
Try Some Simple Solutions
Before you call in the cavalry (AKA HVAC professionals), here are a few things that you can try for a timeout:
Replace or Clean the Filter
Given how simple it is to clean or change an air filter, it's always the first step on my troubleshooting list. Remember, a clean filter not only keeps your AC running optimally but also keeps the air in your house cleaner!
Update Your Thermostat Settings
All it takes is a flick of a switch. Change your thermostat settings from 'ON' to 'AUTO', sit back, and see if your AC starts behaving itself.
Check for Any Ice on the Unit
Sometimes, an overworked air conditioner can freeze. If you see any ice on your indoor unit, turn off your AC and let it defrost. If the situation repeats, definitely call in a pro.
When to Call the Pros
If you've run through my checklist and your AC is still doing its energizer bunny impression, it's time to call in professional help. And remember, a regular and comprehensive maintenance routine with a certified HVAC technician is still the best way to avoid these issues altogether!
The Final Cool Down
Remember, air conditioners may not be the most glamorous part of your home, but a smoothly running AC unit is key to staying comfortable and chill. So, when your AC pulls an all-nighter, don't panic. With this DIY guide in hand, you'll be ready to tackle the issue full on and restore the cool calm!
