4 DIY HVAC Tips for Winter Maintenance

The leaves are golden shades of red and yellow, and the air is crisp, with a bite that sometimes stings the face. You’ve been here before. You know all too well about what’s to come. That’s right, Hoosiers – winter is coming. In the past, you’ve let it sneak up on you, let the cold into the castle before you took account of your HVAC system. But not this year; no, this year – with a little help from Central Indiana’s most trusted heating and cooling company – you’re going to be prepared before winter shows up at your door. Today, the experts at Complete Comfort are going to give you 4 DIY HVAC tips for winter maintenance.

  1. Take Control of Your Thermostats.

Make sure your thermostat is properly working. You want to test and check the thermostat, making sure the settings move throughout the day to the correct temperature. For example, if no one will be home during the day, you want to make sure the thermostat reflects that. When you’re home during winter, the thermostat should be set no higher than 68 degrees.

By taking these steps, the Department Energy estimates that you’ll save 10 percent or more on your energy bill. If you feel 68 is too cold, try dressing warmer while inside the home, and perhaps have that second (or third) cup of coffee. Set the temperature even cooler while sleeping; extra blankets will keep you warm. As it goes back to 68 in the morning, the heat will feel great and help you ready yourself for the day.

  1. Change Your Furnace Filter.

A dirty air filter does two things: a) it slows down the flow of air from the HVAC unit, making it work harder to keep you warm; and b) it allows more indoor allergens and pollution into the home, which can lead to respiratory infections and worsening allergies – not to mention acute asthma in those who are generally more susceptible. According to the Environmental Protection Agency, you should change your furnace filter every month during winter and summer.


  1. Wash and Clean Warm-Air Registers.

Often forgotten and overlooked, warm-air registers trap and hold lots of unhealthy contaminates mold, mildew, pollen, and dust. The fact is, each year your registers should be taken down and thoroughly washed with soap and water. If it’s been a few years since the last time they were taken down and washed, you might need a utility knife to remove them. After the screws have been removed, guide the knife along the edges of the register until it’s freed.  Make sure the register is completely dry before reinstalling.


  1. Bleed Your Radiator.

Bleeding your radiator of air is another important winter maintenance chore that’s often overlooked. If the top of the radiator feels cool to the touch, you need to bleed it of air. As hot water fills the radiator from the boiler, air can become trapped at the top, making the radiator inefficient. Just stick the radiator key into the bleed valve and turn. If the radiator contains air, you will hear a hissing sound as air escapes. When water begins to drain from the valve, all the air has been eliminated and the radiator will be at its most efficient.


While these DIY winter maintenance tips should help your HVAC system run more efficiently this winter, the best way to keep your system in peak running condition is to schedule regular maintenance checkups. Investing in routine checks could save you from expensive repair.
