When the cool, crisp winter air starts to blow in, it’s time for homeowners to start preparing their HVAC systems for the cold! Winter is a tough season on your heating and cooling system. The heaters are running constantly, while windows are left open and fans are blowing nonstop. This can lead to some major wear and tear on your furnace or central air conditioning unit. If you want your home to stay warm this winter without breaking the bank, follow these simple tips.

Change your air filter every 3 months

Try to change the air filter monthly or at least after every 3 months to keep allergens and other contaminants out of the HVAC system, which can lead to a more efficient heating or cooling system in the winter months.

You should change your air filter every three months during colder seasons. This will ensure that all particles are removed from the machine before they have a chance to contaminate your home’s indoor air.

Cleaning vent grills regularly can also help keep the HVAC system running more efficiently during the winter months. Vent grills are located at the end of ducts and tend to accumulate dust and debris from a variety of sources including neglected air filters or outdoor contaminants like pollen or grass clippings when they’re not cleaned periodically.

Install a Programmable Thermostat

A programmable thermostat is a great way to save some money and energy over the winter months. You can adjust this device so that it keeps your home at a constant temperature when you’re away from the house, which can help conserve heating bills!

This also saves you from having to constantly change the temperature when your family members come in and out of the house.

Keep Doors Closed When Not In Use

Make sure doors are closed as much as possible, particularly those leading into an unoccupied room like a bedroom or closet. Drafts can make it difficult for HVAC systems to maintain their optimal thermostat level, so make sure you keep the heat in and the cold out!

Install a Humidifier

During the winter months, humidity levels can get really low. Low humidity can lead to dry skin or respiratory irritations like sore throats or dry coughs as your body tries to produce more moisture. Installing a humidifier is an easy way to keep the air moist and comfortable this winter!

Low humidity can seriously affect your health in winters. Be sure that you take care of this by installing a humidifier in your home as soon as you can.

Lower the Heating Temperature by One Degree

A lot of people think that their home needs more heat once it starts getting cold outside, but the opposite is actually true! If you’re always running at a higher temperature than you need to be, your HVAC system will have a harder time maintaining that optimum level.

Lowering the heating temperature by one degree can also save some money on bills and make it easier for your heater or AC unit to work more efficiently!

Install an insulation kit inside your ducts

Insulation kits will help keep cool air from escaping out of your ducts and heating up the room. This can make it easier for your HVAC system to maintain a temperature level that you’re comfortable at!


If you follow all these steps, you’re sure to have a comfortable winter. Be mindful that your HVAC system still needs a professional inspection at the beginning of every winter season to ensure that it’s running efficiently and you’re not wasting money on energy.
