What Should Routine HVAC Maintenance Include?

Most homeowners know that residential HVAC maintenance is crucial to their home’s comfort. However, most do not understand what goes on during their scheduled maintenance. Without the proper knowledge of what happens during your scheduled maintenance, you risk missing key signs of something wrong with your unit. 

By performing regular maintenance on your HVAC system, you can prevent breakdowns, improve indoor air quality, and prolong the life of your system. The team at Precision Air takes pride in providing transparent service to households around Nashville. We want homeowners who maintain their systems to know precisely what to expect during our visit. 

This blog will cover what to expect during your routine HVAC maintenance, including:

  • Checking overall operation
  • Changing air filters
  • Clearing drains
  • Examining coils
  • Inspect heating systems
  • Measuring refrigerant levels
  • Monitoring fans, blowers, and motors

Your HVAC Maintenance Checklist


Your technician will first make sure that your system is running correctly. During this early inspection stage, your technician will confirm that your system starts, runs, shuts off, and responds to thermostat input. Since you deal with your system daily, they may ask if you’ve noticed any anomalies. 


Your filters are crucial to your home’s indoor air quality, so they are on the priority list when running your routine maintenance. To maintain proper airflow and air quality, your technician will replace your air filters if they haven’t been in over three months. 


Drains ensure that your HVAC system components do not experience clogs. Because clogged drains can affect many aspects of your unit’s operation, your technician will ensure it remains unobstructed. If your drains are clogged, your technician will take the necessary steps to remove it. 

Specific Unit Inspection Checklist


Heat exchange in a space cannot happen without coils. Keeping the coils on your evaporator and condenser clean is essential to ensure your system runs efficiently. By doing so, you can increase the lifespan of your unit and save money on your energy bills. 

Heating elements

When dealing with heating elements, your technician will prioritize safety. To ensure safety, it is crucial to check both gas and oil connections for any defects or damage. If there are any signs of leakage or obstruction, it is vital to address them immediately to prevent any potential risks.


Refrigerants are crucial chemical substances that help cool down your spaces. Your technician will inspect your HVAC’s refrigerant levels to avoid waste, ensure safety, and guarantee proper functions.  

Fan and Blowers

A unit’s motor, blowers, and fans can be the source of many HVAC woes. These components can become damaged if exposed to constant obstructions or impede proper airflow. The assembly of these components should be thoroughly monitored and cleaned during your maintenance appointment.
