An HVAC system tune up is a preventive maintenance service that helps to ensure that your HVAC system is working properly and efficiently. A tune up typically includes the following steps:

Checking the Air Filter

The air filter is located in the air handler, which is usually located in the attic or basement. The air filter helps to remove dust, dirt, and other particles from the air before it is circulated throughout your home. A dirty air filter can restrict airflow and reduce the efficiency of your HVAC system.

To check the air filter, remove it from the air handler and inspect it for dust, dirt, and debris. If the filter is dirty, replace it with a new one.

Cleaning the Condenser Coils

The condenser coils are located outside, near the air conditioner unit. The condenser coils release heat from the refrigerant. A dirty condenser coil can reduce the efficiency of your HVAC system and make it work harder.

To clean the condenser coils, use a garden hose to spray them with water. Be sure to avoid getting water on the electrical components.

Inspecting the Refrigerant Lines

The refrigerant lines are the tubes that carry refrigerant between the condenser and evaporator coils. Refrigerant leaks can cause your HVAC system to lose efficiency and even stop working altogether.

To inspect the refrigerant lines, look for any signs of leaks, such as wetness or frost. If you see any leaks, call a qualified HVAC technician to repair them.

Testing the Thermostat

The thermostat is responsible for controlling the temperature in your home. To test the thermostat, turn your thermostat to the “off” mode and wait a few minutes. Then, turn your thermostat to the “cool” mode and lower the temperature a few degrees below the current room temperature. Wait a few minutes to see if the air conditioner turns on.

If the air conditioner does not turn on, or if it does not cool your home properly, call a qualified HVAC technician to service the thermostat.


By following these steps, you can help to ensure that your HVAC system is working properly and efficiently in the summer. A well-maintained HVAC system can help you to save money on your energy bills and keep your home comfortable all summer long.

Additional Tips for Keeping Your HVAC System in Good Condition

In addition to having your HVAC system tuned up once a year, there are a few other things you can do to keep your system in good condition:

  • Change your air filter every month.
  • Clean the condenser coils once a year.
  • Keep your HVAC system clean and free of debris.
  • Avoid running your HVAC system too much.
  • If you notice any problems with your HVAC system, call a qualified technician immediately.

By following these tips, you can help to extend the life of your HVAC system and keep it working properly for many years to come.
