DIY HVAC Maintenance Tips for Central Illinois Homeowners


Proper maintenance of your heating, ventilation, and air conditioning (HVAC) system is crucial for ensuring efficient operation, prolonging its lifespan, and maintaining a comfortable indoor environment. While it’s always recommended to seek professional assistance from reputable HVAC companies like Pro Air HVAC for major repairs or replacements, there are several DIY tasks you can perform to keep your system running smoothly.

Filter Replacement

  1. Check your HVAC system’s air filters regularly and replace them as needed, typically every 1-3 months.
  2. Dirty filters can restrict airflow, reduce efficiency, and potentially cause damage to the system.
  3. Make sure to purchase the correct filter size and type for your specific unit.

Outdoor Unit Maintenance

  1. Keep the area around your outdoor unit clear of debris, such as leaves, branches, and overgrown vegetation.
  2. Trim back any shrubbery or trees that may be obstructing airflow.
  3. Gently clean the unit’s exterior with a garden hose and a soft brush to remove dirt and debris.

Thermostat Adjustment

  1. Adjust your thermostat settings according to the season and your comfort preferences.
  2. During the summer months, set the thermostat a few degrees higher to reduce energy consumption and strain on your air conditioning system.
  3. In the winter, lower the thermostat a few degrees to save energy while still maintaining a comfortable indoor temperature.

Professional Maintenance

While DIY tasks can help maintain your HVAC system, it’s essential to schedule regular professional maintenance with a certified HVAC technician. Professional maintenance typically includes:

  • Inspecting and cleaning critical components
  • Checking for refrigerant leaks
  • Lubricating moving parts
  • Ensuring proper airflow and electrical connections

Regular professional maintenance can help prevent breakdowns, extend the lifespan of your HVAC system, and ensure optimal energy efficiency.


By following these DIY HVAC maintenance tips and scheduling regular professional service, you can keep your heating and cooling system running smoothly, reduce energy costs, and enjoy a comfortable indoor environment throughout the year. Remember, for major repairs, replacements, or complex issues, it’s always best to consult with the experts at Pro Air HVAC or other reputable HVAC companies in your area.
