Tech Tip of the Month- How to Winterize Your HVAC System

The Philadelphia area may have its first significant snowstorm this week in more than 652 days. As we prepare for the impending storm, we want to share a few tips on how to winterize your HVAC system.

How to Winterize Your HVAC System

Outdoor HVAC units are designed to withstand all types of weather- even the freezing cold temperatures and snow. Winterization is what we can do to prepare our HVAC equipment for the winter months. To maintain maximum efficiency and to ensure proper functionality of your HVAC systems, we recommend the following tips:


In Preparation for the Winter Season:

  • Schedule annual maintenance on your heating equipment each fall. Annual maintenance should include a thorough cleaning of your heating equipment and a changing of filters.
  • Clear the outdoor units (and the surrounding area) of any debris that may have fallen during the fall months. This includes sticks, leaves and shrubbery/plants.


Following a Snowstorm:

  • Remove any snow and debris from the outdoor units, especially heat pumps.
  • Keep outdoor PVC pipes for high efficiency furnaces and boilers clear of any snow.
  • Check that all exhaust vents are clear. Blocked exhaust vents can cause a build-up of carbon monoxide in your home, which is very dangerous.
  • Allow the heat to stay at one temperature for a few days instead of lowering and raising the temperature at certain hours of the day and night. This also applies for radiant heat.



We hope these tips help you stay safe, warm and cozy during the snowstorm. If you have any HVAC issues, please know we offer 24/7 Emergency Service.
