HVAC Tune Up Checklist: What Does It Consist Of?

Around 90% of homes in the U.S. have air conditioning. While most have central AC systems, others might have alternative cooling systems, such as window units.

A properly working system costs less to operate and keeps your home cooler, but how can you keep your system working correctly? The best way is through an HVAC tune up.

You might wonder what an HVAC tune up checklist consists of before you get one. Keep reading to find out.

Change the AC Filter

An HVAC tune up includes checking the air filter. All systems have air filters, and using the correct one is vital. Replacing the filter is also important for HVAC maintenance. 

Therefore, the HVAC company will check your air filter and replace it if necessary. Having a clean air filter is one of many essential reasons to get an AC tune up. 

Inspect the Outdoor Unit

An AC system has two primary components, and one is outside your home. This part is the condenser, and it looks like a big box. You’ll hear this part running if you’re outside when your AC is on.

The condenser contains coils and helps your system release the hot air it conditions. The HVAC company cleans these coils and checks the refrigerant lines. They’ll inspect every other part of the unit. 

Inspect the Indoor Unit

The other part of the system is inside. During the tune up, the technician will examine each part, including the blower motor and fan. They’ll make any necessary HVAC repairs to these parts. 

Clean the System

A heating and cooling system collects dirt, dust, and debris from use. The dirt that accumulates in the system prevents it from working efficiently. Additionally, it can lead to the system failing to operate. 

As a result, a tune up includes cleaning the system. The technician cleans the coils, blower motor, and every other component.

After cleaning each part, they will lubricate the necessary parts, allowing them to function effortlessly. 

Measure the Coolant Level

An HVAC system cools your home by extracting the heat from the air. To complete this process, the system uses coolant. Your system needs a specific level of coolant to operate correctly and efficiently. 

Therefore, a tune up includes measuring the coolant level. They will add coolant to the system if it’s low. They might also check the system for leaks, as the coolant level shouldn’t decrease. 

Calibrate the Thermostat

The thermostat controls when the system turns on and off. However, an improperly calibrated thermostat won’t function properly.

Calibrating a thermostat involves resetting it to ensure it reads the correct temperature, and an HVAC technician will do this if necessary.
