My AC Is Struggling, What Can I Do to Help My Home Be Cooler?

Here's how a maintenance agreement can help if your air conditioner is not properly cooling your home.

AC Repair

A scheduled maintenance agreement can keep your home's air conditioner from struggling to keep up during the hot summer months. There are a variety of things that can cause your AC to run less than optimally. If your system is not cooling enough or running too frequently, there is a very good chance your system is not tuned up to the design specifications.

Here are some troubleshooting steps you can take on your own:

Set the thermostat to "AUTO."

Does your air conditioner blow out cool air sometimes and lukewarm air other times? If so, the fan setting may be set to "ON" which just runs the fan 24/7.

Change the air filter.

A dirty air filter reduces airflow into your air conditioner, causing problems, including:

  • Air conditioner struggles to circulate enough cool air to get your home to the desired temperature (e.g. your thermostat is set on 74 while your temperature never drops below 80).
  • Evaporator coil (the part that cools the air) literally freezes, turning into a cube of ice that blocks air, meaning your air home gets very little cooled air at all.

Clean your outside unit.

The air conditioner's inside unit (called an evaporator) absorbs heat from your air and then transfers the heat to the outside unit (called the condenser). The condenser can't dissipate heat if it is dirty or crowded with debris. This causes your air conditioner to struggle to cool your home.

If you run through the troubleshooting steps and still have a problem, it is time to contact a professional. Here are the issues best left to the pros:

Faulty or broken condenser fan motor.

If the fan motor is bad, then the outdoor unit's fan can't help dissipate heat, meaning that the air conditioner can't cool your home.

Low refrigerant charge/refrigerant leak.

Refrigerant is the liquid that absorbs the heat from your air. When you don't have enough, your air conditioner can't absorb enough heat to cool the air. A low refrigerant level means one thing: you have a refrigerant leak. Other signs you have a refrigerant leak include:

  • Ice buildup on the refrigerant line and the outside unit
  • Bubbling or hissing noise
  • Air Conditioner can't cool your home on especially hot days, but cools fine on cool days and at night.

If you see these signs, turn off your air conditioner and call a professional ASAP. Running the air conditioner in this state can cause slugging in the compressor and can possibly damage it beyond repair.

A bad compressor.

The compressor is the heart of the air conditioning system, circulating refrigerant is like blood between the inside and outside unit. If it's damaged, then the air conditioner can't cool your air. If there is an issue with the compressor, then it may need replacing. Unfortunately, the compressor is an expensive repair. So unless you have a warranty on it, you'll probably need to replace the entire outside unit.
