Winterizing your HVAC system protects air conditioner components through the long, idle winter months while also ensuring your furnace and heating components are operating at peak efficiency and performance during chilly weather. You’ll get lower operating costs and more consistent comfort, as well as ensure that your system complies with warranty requirements for regular service. Here are some things to consider when winterizing your HVAC system as seasons change and temperatures drop.
- Change the system air filter. Don’t go into winter with a dirty air filter left over from summer air conditioner operation. Install a quality, pleated cotton or polyester filter. During the winter, check the filter condition monthly and change it at least every other month.
- Check the vents. Make sure all supply vents in every room are open and unobstructed. Occupants of a home may sometimes close supply vents in certain rooms to block air conditioning during the summer. However, this can disrupt proper airflow balance throughout the entire system and impair consistent indoor heating during the winter. Also, make sure no objects such as furniture or curtains are obstructing vents.
- Schedule annual maintenance. Provided by a qualified, professional HVAC contractor, the service includes an up-close inspection of your furnace to confirm optimum efficiency as well as safety. A list of manufacturer-recommended preventive-maintenance procedures is also adhered to. Annual HVAC maintenance at the outset of the heating and cooling seasons is also usually required to comply with the terms of the furnace and air conditioner warranty.
- Protect the outdoor A/C component. Once you’re certain you won’t be operating the air conditioner until spring, consider a commercially available cover to protect the outdoor unit from winter storms, falling leaves, and other potential damage. Make sure to remove the cover before you use the air conditioner again.
- Update your programmable thermostat. Have your daily habits and occupancy patterns changed since last winter? Check your thermostat and make sure programmed temperatures and time schedules match your current heating preferences.
