As the chilly months set in, your home’s heating system becomes one of its most essential components.
But many homeowners overlook ways to prepare their HVAC unit for winter, and that can lead to surprises like higher energy bills, uneven heating or even system breakdowns when you need it most.
Fortunately, with a little preparation now, you can protect your HVAC unit, extend its lifespan and keep your home cozy and comfortable all season long.
Why Winterizing Matters
When winter hits, your HVAC system faces more stress than in the milder months. In addition to working harder, your outdoor units are also exposed to harsher weather. Snow, ice, wind and low temperatures can cause damage, restrict airflow or even cause the unit to stop working completely.
Inside the home, issues like dirty filters, leaks in the ductwork or malfunctioning thermostats can become magnified during the heating season.
That’s why prepping your system for winter isn’t just about comfort. It’s also about longevity, efficiency and avoiding costly repairs.
The Pre-Winter HVAC Checklist
Here are some essential steps you should take before the cold fully sets in:
- Schedule a professional inspection: A professional HVAC tech will check refrigerant levels and the overall condition of the system. This helps catch issues before they become big problems.
- Replace or clean your air filters: Dirty filters force your system to work harder to keep your home warm. Filters should be changed every one to three months.
- Seal ductwork and check airflow: Leaky ducts result in warm air escaping before it reaches your living spaces. This can result in higher energy costs.
- Inspect and protect the outdoor unit: Make sure your unit is at least three feet away from trees, branches or outdoor items like furniture or kids’ playsets. Consider insulating exposed refrigerant or condensate lines.
- Cover or shelter the outdoor unit: While most units are designed to withstand winter weather without a cover, if your unit is exposed to falling debris or heavy snow accumulation, you might consider a cover. Just make sure it does not trap moisture or restrict airflow.
- Program or test your thermostat: Make sure your thermostat is working correctly, that it’s calibrated correctly and if it’s older, consider upgrading to a programmable or smart thermostat to save energy while you’re away or sleeping.
