Few things are more frustrating than experiencing AC troubles in the peak of summer. In that situation, you’ll want a quick fix for the problem.
Calling an HVAC technician is the obvious solution; however, booking an instant appointment may not always be realistic. Knowing some DIY AC troubleshooting can help you avoid the hassle of enduring uncomfortable temperatures for prolonged periods.
Let’s look at some common air conditioning problems and what you can do BEFORE calling an HVAC technician.
AC Not Turning On
If your AC won’t turn on, the first place you should look is the thermostat. Confirm that it’s set to “cool” and that the temperature is indeed lower than your current room temperature. Replace the thermostat batteries if they are showing signs of weakness.
If the thermostat isn’t the problem, look at the circuit breaker or fuse box to ensure a blown fuse isn’t the culprit.
Insufficient Cooling
This is one of the most common problems plaguing AC units. If your AC is not cooling your home properly while running, the focus of your AC troubleshooting should be on checking for clogs in the system.
The obvious starting point is the air filter – if it’s clogged, be sure to replace or clean it. Next, check the vents to ensure they are not blocked.
Noisy Operation
If your AC is making any grinding or squealing noises, it often points to a mechanical issue. Check the fan motor to ensure it’s not bent.
You can also lubricate the joints of the blower motor using the manufacturer’s recommended product(s). If you can’t figure out the source of the noise, turn off the unit until an HVAC technician arrives.
Continuous Cooling Cycle
If your AC suddenly starts running continuously without ever cycling off, you should first check the thermostat setting. If the settings are fine, confirm that the thermostat is not in direct sunlight. The system will run continuously if the thermostat is misreading the temperatures.
If the thermostat isn’t the problem, you may have a refrigerant leak. Low refrigerant levels will cause the unit to work longer to cool your indoor space. This is an issue best left to HVAC technicians.
Water Leaks
Water leaks indicate a clogged condensate drain line. You can clear out the line with a vacuum or a thin wire.
Musty or Burning Smell
Cleaning the filter can help reduce the musty smell in the atmosphere. Burning smells are more serious and require the help of an HVAC expert. They often point to internal electrical problems that require urgent attention.
