Prepare Your Home's Heating System for Winter

 

 

We've had some cold nights but don't commit to the flannel sheets yet. Virginia's weather can be fickle! According to NOAA, we should get used to this mixed bag of weather as La Niña climate patterns develop. Virginians have an equal chance of above, near, or below-normal precipitation this winter. Past La Niña winters have brought warmer-than-average temperatures for the commonwealth but precipitation can vary greatly. 

Rain, sleet, snow, rain; we're talking bouts of unseasonably warm days followed by dives into colder temperatures and all the precipitation in-between. With all this uncertainty, one thing is for sure: colder weather is coming. And whenever you do feel chilled this winter, you'll want your home's furnace to be happily humming. Spending a little time and money now and save a bundle later!

How to prepare your home’s heating system for winter

Winterization for furnaces, heat pumps, or any heating system

You wouldn’t leave for your Thanksgiving travel without checking your car engine’s oil or the air pressure in the tires, right? Right! So it’s definitely a good time to get your furnace ready for its winter journey. Here are the 4 simple ways to prepare:

1. Have an annual inspection by an HVAC professional.

HVAC systems are complex and require a trained pro to get them running right. Heating professionals check things like coils, pressure and airflow, burners, and your heat exchanger. Dealing with a system failure is not pleasant when it’s freezing outside, not to mention it could damage other home systems. Let’s do it right!

2. Change or clean your air filters.

Don’t wait until you hear that terrible sound of heat ducts popping in and out when the heat turns on and off. It's best to replace air filters monthly. If you’re not sure if you’ve gotten your money’s worth from your existing filters, here’s a better measure. Buy new filters and compare them to the old ones in front of bright light. If you can’t see light filtering through the old filters, replace them.

 

3. Clear leaves and debris from around your exterior HVAC unit. 

Remove any vegetation, leaves, and mulch from around your outdoor heat pump. For an HVAC system to run as smoothly as possible, air should be able to flow unimpeded through the condenser.

4. Clean your duct vent inlets.

Your home's duct vent inlets are intaking or distributing air into your cooling and heating system any time your air or house fan is running. The largest vent is usually your return duct and can get pretty dirty. This is a good reason to replace filters frequently and to clean your return vents from time to time.  You most likely have smaller vents in your floor or ceiling that blow heated or cooled air into your rooms. Those can use a good vacuuming at the same time.

This is a job tackled simply with your vacuum’s brush attachment tool. That annual inspection professional can also inspect the inner ductwork for cleanliness, insulation, and tight connections. You can also opt to have your ducts professionally cleaned. 

5. Reverse your ceiling fans.

Give your furnace a little help this winter by recirculating the naturally rising warm air trapped at your ceiling.

Once your heat is running consistently, find the small black switch on the motor housing of your ceiling fan to change the spin direction clockwise.
