When the cold months roll into Quincy, your HVAC system becomes more than just a comfort—it’s a necessity. At Aspinwall Plumbing & Heating, we know how important it is to keep your heating system running smoothly all season long. With a few proactive steps, you can avoid mid-winter breakdowns, save on energy bills, and extend the life of your equipment.

Here’s how to maintain your HVAC system in winter and keep your home warm and worry-free.

1. Replace or Clean Your Air Filter

A clogged or dirty air filter can severely restrict airflow, forcing your system to work harder than it should. This leads to higher energy bills and potential overheating. We recommend checking your filter once a month and replacing it as needed—especially during peak winter usage.

2. Schedule a Professional Inspection

The best way to ensure your HVAC system is winter-ready is with a professional tune-up. At Aspinwall Plumbing & Heating, our experienced technicians inspect your entire system, clean components, check for wear and tear, and fine-tune performance to catch issues before they cause trouble. Call us at (617) 539-7672 to schedule your winter maintenance today.

3. Keep Vents and Registers Clear

Furniture, curtains, and even rugs can block air vents and registers without you realizing it. Blocked vents make your system work harder, resulting in uneven heating. Take a few minutes to check every room and ensure vents are clear to allow for proper airflow and balanced warmth throughout your home.

4. Monitor Your Thermostat Settings

It’s tempting to crank up the heat, but that can lead to higher utility bills and wear on your system. Set your thermostat to a consistent, energy-efficient temperature—typically around 68°F when you’re home. Consider upgrading to a programmable thermostat for even more control and savings.

5. Inspect Your Outdoor Unit

If you have a heat pump or dual system with outdoor components, keep the area around the unit free of snow, leaves, and debris. This ensures proper airflow and helps your system operate more efficiently, even in cold weather.

6. Seal Drafts and Insulate

Even the best HVAC system can struggle if your home isn’t properly insulated. Check for drafts around doors and windows, and seal them with weatherstripping or caulk. Good insulation keeps warm air inside and reduces strain on your heating system.
