Practical DIY HVAC Tips for Homeowners


Maintaining your home’s heating, ventilation, and air conditioning (HVAC) system can be a daunting task, but with a few simple DIY tips, you can keep your system running smoothly and save money on costly repairs. In this article, we’ll cover some practical DIY HVAC tips for homeowners in St. George, UT, Cedar City, UT, Washington, UT, Santa Clara, UT, and Ivins, UT.

Air Filter Replacement

One of the most important DIY HVAC tasks is replacing your air filters regularly. Clogged air filters can restrict airflow, reduce efficiency, and potentially cause damage to your HVAC system. Check your owner’s manual for the recommended replacement schedule, typically every one to three months.

Outdoor Unit Maintenance

  • Keep the area around your outdoor unit clear of debris, such as leaves, branches, and overgrown vegetation.
  • Use a garden hose to gently wash away any dirt or debris from the unit’s fins and coils.
  • Ensure that the unit is level and stable, as tilting or rocking can lead to leaks or other issues.

Thermostat Settings

Properly setting your thermostat can help you save energy and reduce your utility bills. Consider the following tips:

  • In the summer, set your thermostat to 78°F (25.5°C) or higher when you’re at home and awake.
  • In the winter, set your thermostat to 68°F (20°C) or lower when you’re at home and awake.
  • Use programmable or smart thermostats to automatically adjust the temperature when you’re away or sleeping.

Ductwork Inspection

Inspect your ductwork for any signs of leaks, tears, or disconnections. Leaky ducts can cause your HVAC system to work harder, resulting in higher energy bills and potential equipment failure. If you notice any issues, it’s best to contact a professional for repairs.

Professional Service and Maintenance

While many DIY tasks can help maintain your HVAC system, it’s essential to schedule regular professional service and maintenance. A certified HVAC technician from S & S Mechanical Plumbing, Heating & Cooling can perform a thorough inspection, clean the system components, and identify any potential issues before they become major problems.


By following these practical DIY HVAC tips, you can help extend the life of your system, improve its efficiency, and potentially save money on energy bills and costly repairs. However, remember that some tasks are best left to professional HVAC technicians to ensure the safety and proper functioning of your system.
