As the weather begins to cool down, now is the perfect time to make sure your furnace is ready to keep you comfortable through the cold months ahead. Having the system professionally serviced will help avoid furnace repairs and high energy bills. However, you can also follow a few simple steps to ensure your system is running smoothly; review them below. 

How to Prepare Your HVAC System for Winter

1. Replace Air Filters

Filters screen debris such as pet hair and dirt that can clog the HVAC system. As they become dirty, they block airflow and cause the equipment to work harder to cool or heat your home. Dirty air filters can increase your energy bills and cause excess wear and tear on your HVAC system.

HVAC contractors recommend changing the filters at least every three months. However, if you or your family members have allergies or respiratory conditions, consider replacing the screens once a month. 

2. Clean Heating Registers & Ducts

Make sure warm air can move freely into your home by cleaning the heating registers. Dust and debris can obstruct airflow, making the system inefficient. The furnace can also blow debris into your home, diminishing your indoor air quality.

To clean the registers, turn the system off and remove the vent covers with a screwdriver. Wash them with dish soap and water. Clean inside the air ducts as far as you can reach using a vacuum's crevice tool or a cobweb duster. Replace the vent covers when they're dry.

Maintain clean registers by wiping down the vent covers with a damp cloth once a month. Also, to ensure efficient airflow in your home, move large furniture or other objects that could obstruct the warm air coming from the registers.

3.  Protect the Outdoor Unit

Get your HVAC system ready for winter by clearing away vegetation and debris from the outdoor unit. It's important to ensure efficient airflow even when the unit isn't running; this will protect the system from corrosion.

Consider covering the unit to protect it during the winter months. However, make sure that the cover is made from a breathable material that won't trap moisture that could cause corrosion and damage the unit.
