Dec 3, 2024. Updated Jan 23. Audree Grubesic.

The article gives five winter maintenance steps for an HVAC system. It says the goal is to improve heating performance, reduce energy use, and keep a home warm.

Five tips to winterize an HVAC system

1. Clean ducts and vents

• Dust, pet hair, pollen, and other particles can collect in ducts and vents during summer.
• Blocked airflow can force the furnace to work harder and create cold spots.
• Vacuum around intake and return vents.
• Remove vent grates and check for deeper clogs.
• Adjust airflow in harder-to-heat rooms, especially on the first floor.

2. Replace the air filter

• Dirty filters strain the HVAC system and can raise energy costs.
• They can also let more contaminants into the home.
• Check the filter by holding it up to the light.
• Replace it if it looks dark or hard to see through.
• Recommended replacement interval: every 1 to 3 months.

3. Test the heating early

• Turn on the heating system before cold weather fully sets in.
• Run a couple of test cycles.
• Listen for unusual noises or signs of trouble.
• Some manufacturers recommend “warm-up cycles” when switching from cooling to heating.
• Check the owner’s manual for your unit.

4. Seal doors and windows

• Inspect insulation around doors and windows.
• Gaps and cracks can let warm air escape.
• Patch leaks with weather-stripping or caulk.
• An airtight seal can help the system run more efficiently and reduce energy costs.

5. Inspect the furnace area

• Keep three to four feet of clearance around the furnace.
• Clear space helps airflow and reduces potential hazards.
• If the furnace is hard to reach, call a professional for an inspection.

Unico System mentioned in the article

• The article says The Unico System provides even, draft-free warmth with whisper-quiet operation.
• It describes the system as a small-duct, high-velocity design.
• It says insulated ducts help prevent heat loss and reduce winter energy bills.
