Milford, NH Homeowner Plans Ahead
Snow and debris can build up outside of your home, blocking the furnace vents that lead outside. Snow or ice impeding the airflow outdoors can cause the entire furnace to malfunction. Most newer furnaces will automatically shut off if the airflow is restricted, preventing serious damage to the HVAC system. When the unit continues to run with these vents blocked it can cause carbon monoxide to build up indoors, creating a dangerous environment. It is important that after each snowstorm you check these outdoor vents, clearing snow away from the area to ensure that the furnace will have proper airflow.

Beyond Snow, Frost and Ice Can Also Impede the Furnace’s Airflow
Any time there is a large snowfall, or any snowfall with drifts that can be blown against or near the home, it is important that the snow be cleared away from the furnace vents. What some homeowners don’t realize is that the airflow can also be impeded by frost and ice building up around the vent’s opening. While this may not be enough to completely shut off the airflow, it can affect the efficiency of the entire HVAC unit with restricted airflow. This means that the furnace will have to work harder to heat the home, costing more to run and likely heating inefficiently. Regularly check the vent for ice or frost build-up throughout the winter. Taking the time to clear this away will ensure that your heating unit is running at peak performance, while also eliminating the risk of carbon monoxide building up inside the home.
Locating the Home’s Outdoor Furnace Vents
The furnace vents are typically located near where the furnace is on the inside, although this is not always the case. Look for a set of curved pipes, generally PVC, coming from the home to the outdoors. Many times these are in the foundation but in some cases the vents may be near or on the roof of the home. It is important to know where these vents are prior to snowfall so that you will know what area needs to be cleared.
The Milford homeowner has already begun checking the furnace vents regularly for ice and frost build-up and she will be ready to clear the area when there is any significant snowfall.
