How do I protect my HVAC in the winter?

Although the outdoor units of most HVAC systems are designed to withstand the harsh outdoor elements, severe impacts of some elements can cause serious damage. You need to protect your HVAC to get the best of its services throughout the winter. Here are some HVAC maintenance tips in the winter.

  1. Snow and Ice Build-up

Snow and ice are dangerous for HVAC systems. Your system can freeze or experience an emergency shutdown. This will leave you at the mercy of the cold. No heat will be supplied to the house, and the pipes might start to freeze as well, which will cause plumbing issues.

To avoid this kind of ugly situation, keep the space around the outdoor units clear. If it is likely to snow for long-reaching several feet, clear the surrounding of the unit, at least two feet around it. Also, do not cover the tip and sides of the unit. And when removing ice from the unit, do not use a sharp object to avoid damaging the coil and fins.

  1. Keep the Exhaust Unblocked

The exhaust of your HVAC unit must be clear and free to run effectively. A blocked exhaust will cause carbon monoxide to seep into the house, causing serious health issues for the family. Also, your HVAC will not run effectively if the exhaust is blocked.

Because of the above, you should check your furnace’s exhaust and ensure that it is not blocked. Also, install a carbon monoxide detector in your home for your safety, to avoid poisoning.

  1. Keep Air Intake Vent Clear

As fumes from the exhaust get dispelled, fresh air must get into the home. As a result, ensure that the air intake vent is not blocked by ice. A blocked intake vent will cause the HVAC to be deprived of the air needed for contribution.

If your furnace tries to start up but fails to turn or, the chances are that its air intake vent is blocked. Clear the vent, reset the furnace, and restart it.

  1. HVAC Maintenance

Another crucial way to protect your furnace in the winter is through prompt HVAC maintenance. You must ensure that the HVAC is working properly. Call in an expert to change its filters – air filters and oil filters. Ensure that the vents are free from debris and any blockage.


An efficiently running HVAC is a joy to homeowners in the winter. Follow the tips above and ensure HVAC maintenance to keep your HVAC working fine throughout.
