Use These Tips to Prepare Your HVAC System for Winter

August 23, 2022

When you imagine winter, we hope you imagine a cozy evening at home. But once in a while winter decides not to go along with our plans, and we're left shivering in our own homes. You may not be able to stop a blizzard from showing up, but you can prevent your heating from being unprepared for winter. Nobody wants or deserves an unreliable furnace, which is why we made this checklist for getting your HVAC system prepped for winter.

Five Ways to Prepare Your HVAC for a Winter Blast

1. Wrap up Your Outdoor Unit and Clean the Space Near It

Since most HVAC systems have an outdoor condenser unit to dispel heat, you'll want to make sure that the area surrounding it is clean of any yard debris. Clear 5 feet of space or so from any plants or sticks. It's also recommended to make sure it's covered by a section of tarp or similar material through the winter. This keeps ice and anything else from getting inside the condenser.

2. Rinse or Replace the Air Filter

Always inspect and clean out your air filter, customarily found in your furnace's indoor air handler. Dust, pollen, animal dander and many other contaminants can steadily build up in the air filter. If it goes unchecked, your furnace can lose efficiency and potentially even become a fire hazard. A clean air filter allows air to flow easily, sustaining adequate ventilation and helping keep indoor air quality healthy. To secure the most benefit from your filter, make sure to clean or change it every two or three months or based on manufacturer instructions.

3. Clean the Blower

The blower is crucial to your Lennox furnace, and as a key component it can accumulate a lot of wear and tear. Cleaning it on occasion will help it continue working at its best. Vacuum the area near the blower and brush the blades with a microfiber cloth for more efficient airflow. If you notice any strange noises or aren't getting any circulation from the vents, call a professional technician to examine your blower.

4. Search for Gaps or Dents in Your Furnace

Make sure that your furnace is free of visible damage on the inside or outside units. A hole in the air handler or damage to the condenser unit outside could contribute to all sorts of comfort problems, like heat escaping before it moves into your ductwork. If there is significant damage, talk to your local technician at Marcos AC & Heating about examining the system before the temperatures begin to drop. This way you can avoid letting a small gap in the system grow into a major problem.

5. Test Your Furnace Before It Gets Too Cold

It's always wise to make sure your furnace is working properly before its busiest season. If you don't, your heating might be unprepared for the first real drop in temperatures. Performing a test run of your furnace can offer you the opportunity to recognize potential problems right away, while they're still more straightforward to solve. This also burns off any dust that may have accumulated in the air ducts beforehand, eliminating that burnt smell. As soon as your furnace is in working condition, you can sled away from your HVAC worries.

A Well-Prepared Furnace Is a Great Way to Welcome Winter

Winter weather is going to be on its way before you know it. If you spend some time to get your furnace ready beforehand, you can spend the rest of the season enjoying the holidays, having hot cocoa or spending time with your family inside a warm, cozy home. Be sure to follow the tips above to get your home ready for next winter!
