How to Prepare Your HVAC System for the Winter

As the winter chill sets in, it’s crucial to ensure that your heating, ventilation, and air conditioning system are ready to handle the demands that cold weather bring. A well-maintained HVAC system not only keeps your home comfortable but also helps improve energy efficiency. We’ve created a comprehensive checklist for winter to ensure a cozy and cost-effective winter season.


Inspect and Replace Air Filters

Begin by checking and replacing your HVAC system’s air filters. Dirty filters can reduce airflow, making your system work harder and less efficiently. Regular replacements during the winter months ensure optimal performance and air quality.

Check Thermostat Settings

Verify that your thermostat is programmed for winter settings. Lower the temperature when you’re away to save on energy costs, adjusting the temperature to a comfortable level when you’re home. Consider upgrading to a smart thermostat for more precise control and energy savings.

Seal Leaks and Insulate

Inspect windows and doors for drafts, sealing and gaps with weatherstripping or caulk. Proper insulation in your home helps retain heat, reducing the workload on your HVAC system and lowering energy bills.

Schedule Professional HVAC Maintenance

Arrange for a professional HVAC inspection and maintenance service before the peak of winter. Maintenance is key to increasing energy efficiency and ensuring the longest possible service life for the appliances in your house that keep your family in comfort around the year. A technician can identify potential issues, clean components, and ensure your system operates efficiently throughout the season. To make maintenance easier for our customers and an even greater value, we offer an A+ Maintenance Membership.

Clean Vents and Ducts

Clear dust and debris from your vents and ducts to maintain optimal airflow. This not only improves indoor air quality but also helps your system distribute heat more effectively. We don’t offer duct cleaning at Associated Heating & Air Conditioning, however, we recommend contacting Advantage Air Duct Cleaning.

Test Carbon Monoxide & Smoke Detectors

Safety is paramount, especially during the heating season. Test carbon monoxide and smoke detectors to ensure they are functioning properly. If you have older detectors, we offer carbon monoxide detector replacement and smoke detector replacement. We’re dedicated to your 100% satisfaction as well as your safety. Consider installing additional detectors, if needed. Our electricians will install carbon monoxide and smoke detectors into your house and see that they work just as you need them to.

Check the Condensate Drain

Inspect the condensate drain to prevent clogs, which can lead to water damage and affect your HVAC system’s efficiency. Ensure proper drainage to avoid potential issues that can be costly.

Inspect Outdoor Unit

If you have an outdoor HVAC unit, make sure it is always free from debris, such as leaves or snow. Proper clearance for airflow ensures optimal performance and prevents damage to the unit. Check your outdoor unit often, especially after stormy weather or any accumulated snowfall.

Replace Aging Equipment

If your HVAC system has aged or shows signs of inefficiency, it might be time to consider upgrading to a more energy-efficient model. A newer system often provides better performance and lower energy bills. At Associated Heating & Air Conditioning, we work with a variety of reputable brands to choose from. Take advantage of the promotional offers we currently have available, including 0% Financing, on approved credit.

Stock Up on Supplies

Oregon weather is always unpredictable this time of year, it’s best to be prepared for unexpected stormy events. Stock up on essential items like air filters, thermostat batteries, and emergency heating supplies to handle any unforeseen circumstances.


Taking the time to complete this checklist can make a significant difference in your home’s comfort and energy efficiency. By staying proactive and addressing potential issues before they escalate, you’ll ensure a warm and worry-free winter season for you and your family.
