Air conditioners are often forgotten until they stop working. Before you call for repair service, here are some helpful tips to troubleshoot common air conditioning problems. Minor problems can be rectified by the homeowner. More complex problems are best left to the professionals who know how to test all the components of a system.

What to Do When Your AC Doesn’t Turn On

If the unit doesn’t come on, check the electrical connections. Has a circuit tripped? If the power is connected, try lowering the thermostat. If the unit still does not come on, it may be best to call a professional.

Why Your Air Conditioner Isn’t Cooling

If the unit is running but is not cooling properly, it could be a dirty condenser or evaporator coil. A dirty filter is a common reason for air conditioner malfunction. Regularly cleaning or replacing filters keeps dust and debris from circulating within the system. Condensers and evaporator coils work their best when airflow is unimpeded; reduced airflow reduces efficiency and can eventually cause the unit to fail.

How to Ensure Your HVAC Unit Operates at Peak Performance

There are simple ways to make sure your AC unit runs efficiently:

  • A poorly calibrated thermostat can cause temperature swings. Make sure the device is level and clean.
  • Keep grass and vegetation trimmed around the condenser unit. Leaves and debris blown into the housing can affect air circulation.
  • Shrubs can provide shade to keep the unit from heating up, but plant at least three feet away. Leave an opening in hedges for access to the unit.
  • Get regular tuneups.
  • Familiarize yourself with the heating and air conditioning information in your owner’s manual.

Choose the Best HVAC Contractor

You can make sure you get qualified professional service by asking a few questions:

  • Is the company licensed? Do they carry adequate liability and insurance coverage?
  • Are technicians certified by NATE?
  • Get the names and numbers of references and call them.
  • Get estimates, contracts, and guarantees in writing.
