HVAC Tune Up Checklist: What Does It Consist of?

March 2, 2023

During the winter season, it is important to make sure that your HVAC system is running efficiently.

A properly maintained HVAC system not only ensures a comfortable indoor environment but also helps to reduce energy consumption and lower utility bills. One of the best ways to keep your HVAC system running smoothly is to schedule regular tune-ups. In this blog post, we will provide you with an HVAC tune-up checklist to help you prepare for your next tune-up.


Check the Thermostat

The first step in an HVAC tune-up is to check the thermostat. The thermostat is the control center for your HVAC system, and it is important to make sure that it is functioning properly. The technician will check the settings, clean the thermostat, and replace the batteries if necessary.


Inspect and Clean the Air Filters

The air filters in your HVAC system play an important role in maintaining good indoor air quality. Dirty air filters can cause your HVAC system to work harder, leading to higher energy consumption and increased utility bills. The technician will inspect and clean or replace the air filters, depending on their condition.


Clean the Condenser Coils

The condenser coils in your outdoor unit are responsible for removing heat from the indoor air. Over time, these coils can become dirty and clogged, reducing their efficiency. The technician will clean the condenser coils to ensure that they are functioning properly.


Inspect the Evaporator Coil

The evaporator coil is responsible for removing moisture from the indoor air. If the coil is dirty or clogged, it can reduce the efficiency of your HVAC system. The technician will inspect the evaporator coil and clean it if necessary.


Check the Electrical Connections

The electrical connections in your HVAC system are important for proper functioning. Loose or corroded connections can cause your HVAC system to malfunction. The technician will check and tighten the electrical connections as necessary.


Check the Blower Motor

The blower motor is responsible for circulating air through your HVAC system. If the motor is not functioning properly, it can cause your HVAC system to work harder and reduce its efficiency. The technician will check the blower motor and lubricate it if necessary.


Check the Refrigerant Levels

The refrigerant in your HVAC system is responsible for removing heat from the indoor air. If the refrigerant levels are low, it can cause your HVAC system to work harder and reduce its efficiency. The technician will check the refrigerant levels and add more if necessary.


Check the Ductwork

The ductwork in your HVAC system is responsible for distributing air throughout your home or office. If the ductwork is damaged or clogged, it can reduce the efficiency of your HVAC system. The technician will inspect the ductwork and repair or clean it if necessary.


Lubricate Moving Parts

There are many moving parts in your HVAC system, including the blower motor, fans, and bearings. These parts require lubrication to function properly. The technician will lubricate these moving parts to ensure that they are functioning properly.


Check Carbon Monoxide Levels

Carbon monoxide is a colorless, odorless gas that is produced by fuel-burning appliances such as furnaces and boilers. If the levels of carbon monoxide in your home or office are too high, it can cause health problems. The technician will check the carbon monoxide levels in your HVAC system to ensure that they are within safe limits.


An HVAC tune-up is an important part of maintaining your HVAC system. It ensures that your system is running efficiently, reducing energy consumption, and lowering utility bills. By following this HVAC tune-up checklist, you can prepare for your next tune-up and ensure that your HVAC system is in good working order. Remember to schedule your HVAC tune-up at least once a year to
