Central air conditioning units maintain an even temperature regardless of how hot it gets outside. But even though they are meant to last a long time, you are going to need to repair them now and then.

The good thing is that the issues with the AC revolve around a few fundamental problems. Here, we will talk about the three most common repairs and how to detect a problem in the first place.

LOW REFRIGERANT LEVELS

Refrigerant, or Freon, as it is commonly known, is the chemical AC uses to draw the heat from your home and release it outside. It’s available in either gas or liquid form, which it can also switch effortlessly between.

This makes it an ideal substance for the AC as the unit doesn’t need to use too much energy. Low refrigerant levels are by far the most common AC repair, and something homeowners need to pay attention to. A quick response is essential, so watch out for these signs:

  • It takes quite a long time for rooms in your home to cool off
  • The temperature set on the thermostat cannot be reached
  • The electricity bill keeps getting higher every month
  • There’s ice residue on the refrigerant lines
  • Water is leaking close to the unit
  • There are bubbling or hissing noises coming from the AC

PROBLEMS WITH THE BLOWER MOTOR

Blower motor problems are another common issue your AC might have during the hottest days of the year.

The purpose of the blower motor is to blow cool air through the vents of the house. It does this by spinning a fan, which then moves the air through the ducts.

There are two types of blower motors: the single-speed and variable-speed. Both of which will eventually show signs of wear and tear. Here are the signs that your AC is having blower motor problems:

  • Noticeably weaker airflow coming from the vents
  • No airflow whatsoever
  • The blower motor is overheating, and there’s a burning smell from the vents

DIRTY EVAPORATOR COILS

For the AC to work correctly, the evaporator coil is essential because it provides comfort indoors when temperatures outside are incredibly high.

But it’s also one of the AC components that malfunctions frequently. Here’s what you might notice when the evaporator coil components are damaged:

  • Warm air coming from the vents
  • The AC won’t turn on
  • The AC turns on and off frequently but doesn’t cool your home properly
  • Refrigerant is leaking close to indoor cooling system elements

These are all symptoms of either a dirty evaporator coil or an evaporator coil leak. An evaporator could also become frozen, which is an issue that needs to be addressed as soon as possible.

KEEP YOUR AC UNIT WORKING FOR LONGER

There are significant differences in quality and longevity when it comes to AC units, but even the cheapest unit should work for at least ten years.

But even the best AC units need maintenance and occasional repairs. If you catch any of the three problems listed above on time, the repairs should be a straightforward job.
