Are you having air conditioner problems?

Now the HVAC industry is worth billions, AC units aren’t as likely to break down. However, some issues persist because of various external factors. They often start small and subtle, so they’re difficult to detect.

Don’t let these problems get out of hand.

In this guide, you’ll learn some common AC issues. Read on and fix these common AC repairs before they turn into larger ones. 

8 Air Conditioner Problems Homeowners Encounter

  1. Clogged Filters

In most cases, filters get clogged because of the accumulated dirt. When it happens, the filter restricts your AC unit’s airflow. It prevents the system from cooling the air effectively.

When you let the problem persist, the clogging will also damage the coils. It decreases their effectiveness in lowering heat. Before long, it will cause a bigger problem.

To avoid this issue, clean your filters regularly. It’s also best to replace them once per month. It’s especially important if your household owns a pet since their fur will likely contribute to the clogging.

  1. Thermostat Problems

Thermostats are for measuring your current air temperature. It automatically adjusts according to your preferences. It’s a great feature, especially when you invest in smart thermostats with mobile features.

However, a faulty thermostat sensor measures temperatures incorrectly. It will cause your home to be colder or hotter than normal. In most cases, it’s because it’s not in its right position.

Check whether the thermostat is in its right place. If not, put it back and see if it solves the issue.

  1. Low or Leaking Refrigerant

Freon is the chemical responsible for cooling the air in your AC unit. Ensure your refrigerant levels are correct to avoid problems. 

A good reason for inappropriate refrigerant levels is undercharging the AC during installation. If it isn’t, the other is a leak in the refrigerant system. This problem is harmful to the environment.

You might suffer from refrigerant poisoning if the problem lingers. Call an HVAC company for an air conditioner repair. Calculate the cost to service an air conditioner to better prepare your budget.

  1. Leaking Air

Most homeowners use window units as an air conditioner component. These have seals to prevent cold air from getting out. At the same time, it keeps hot air from getting in.

When your window unit’s seals break or wear away, the cold air will seep out. It’s a slow process, but it causes your system to work harder. It lowers efficiency and raises your electric bills.

To solve this issue, use weatherstripping to reseal your window unit.

  1. Dirty Registers

Registers often get dirty, like your filters. When you don’t maintain their cleanliness, the air must go through the dust and dirt within your system. It increases your air conditioner’s burden.

Dirty registers are easy to solve. Use a vacuum to remove debris within. Do it regularly to ensure the problem won’t arise.

  1. Unresponsive AC unit

When your air conditioner won’t turn on, it’s likely because of an electrical issue. If your thermostat is active and has the correct settings, check your circuit breaker. Discover whether it tripped or blew a fuse.

When your circuit breaker is in good order, the problem is in the airflow. Dirty filters, coils, and other components cause poor cooling and lead to failure. It could also damage the compressor permanently.

Call the professionals when your AC won’t turn on after changing your filter. It’s especially when it’s a recurring problem. It’s not a problem you can DIY since it’s too dangerous.

  1. Water Leaks

Water leaking from your indoor AC unit comes from neglect. The system’s condensate drain becomes infested with fungi or algae. It causes water to back up the pipe, leaking into your house.

In some cases, the condensate pump already broke. It means you’ll need a replacement soon. Contact an HVAC technician to ensure proper installation.

For clogged condensates, use a wet or dry vacuum to unclog them. Pour around six ounces of vinegar in the drain line. It’s an efficient DIY method for killing fungi and algae.

During hot summer days, a puddle of water can form under your AC compressor outdoors. It’s likely because of the following issues:

  • Broken condensate pan
  • Improper AC installation
  • Broken seals

When you see this problem, deactivate your air conditioner. Disconnect it from your power supply. Call a professional since it’s a tricky problem to deal with alone.

  1. Air Conditioner Noises

When you hear screeching or squealing sounds, it’s from the blower motor. It’s either a bearing issue or a faulty belt. The latter is often at risk of breaking, so add some lubricant to the oil port.

Clanging or banging sounds are often because of a motor or blower assembly issue. Turn off the AC unit as soon as you hear these noises. Call an expert and let them deal with the problem.

When things get stuck in your blower blades or their surrounding housing, it makes smacking noises. Turn your air conditioner off and look for debris in the blower. Remove them and clean the component before turning it back on.

Clicking sounds whenever you toggle your air conditioner means a relay issue. Never bother with DIY and call a professional for an inspection.

Broken Air Conditioner Repair Considerations

Are you planning to repair your air conditioner on your own? Think about its warranty before doing so. Changing the filters and other basic maintenance is okay in most cases.
