Furnace Maintenance

Furnace maintenance is the routine servicing of your heating system to ensure safe, efficient, and reliable performance all winter long. At SumZero, we specialize in expert furnace maintenance across Massachusetts to help you avoid costly breakdowns, lower energy bills, and extend the life of your system.

Annual Furnace Maintenance for Reliable Winter Comfort

When cold weather hits Massachusetts, your furnace becomes your home's best defense. Scheduling annual furnace maintenance ensures that your heating system runs safely, efficiently, and without unexpected surprises. At SumZero, we provide thorough checkups that keep your system in top shape—so you stay warm without high repair bills or energy costs.

How Often to Service Furnace

Experts recommend scheduling furnace maintenance at least once a year, ideally in the fall before peak heating season. This helps:

  • Catch problems early before they become pricey repairs
  • Maximize energy efficiency through system cleaning and tune-up
  • Extend the lifespan of your furnace
"Neglecting annual furnace maintenance can reduce efficiency by up to 30%, leading to higher energy bills and early system failure."

Tune-Up Checklist

A professional furnace tune-up typically includes:

  • Inspecting burners, blower motor, and igniter
  • Checking for gas and carbon monoxide leaks
  • Lubricating moving parts to reduce wear
  • Testing system controls for safety
  • Cleaning furnace filter for better airflow

These steps not only improve operation but also offer peace of mind during every cold snap.

Home Furnace Maintenance Tips for Massachusetts Winters

Massachusetts winters can be especially demanding on heating systems. Taking simple steps between annual visits helps your furnace work smarter, not harder.

Heating Maintenance Tips

To support system health year-round:

  • Change your furnace filter every 1–3 months
  • Keep vents and returns free of dust and obstructions
  • Seal any drafts near doors and windows
  • Schedule a professional HVAC inspection yearly

A maintained furnace runs smoother, heats faster, and uses less energy—keeping your bills lower even when the temperature drops.

Clean Furnace Filter = Clean Indoor Air

Don’t underestimate the impact of a clean filter. It traps dust, allergens, and debris, preventing buildup in your system and improving indoor air quality for your whole family.

What Local Homeowners Are Saying

See how SumZero has helped local homeowners stay comfortable year-round with energy-efficient heat pump solutions.

We hired SumZero to install a ductless mini split system and it was a great overall experience, David Sampaio helped quote and spec out the install and was great at coordinating the project. The team who installed everything completed the job in only a few hours: they were professional, fast, and cleaned up well. They even went above and beyond to help me check something unrelated to the install on the outside of my house. Very easy company to work with and we're very pleased with their work so far.

Over-the-top outstanding communication with company throughout process. In this area, never seen anything like it from contractors. They mostly setup masssaves heat loan for me: as much as they can, and were patient, attentive as I waited on that process. They even encouraged it (if that’s what I wanted.) NO other company among 4 competitors did that. Do your homework, see pictures, you’ll see this co. does neat and tidy work, and their technical expertise seems to match that. I’m actually proud that we found and picked them, for my part. In the end, still work done by contractors, so important to know what people typically find wrong with type of work you’re having done, and keep an eye out for those things. The few small details I pointed out, sum zero guys were all over it, no pushback. And…they are ahead of the game in that area too: they have experience and have clearly learned from it. The could explain why they recommend what they recommend based on customer feedback. They are very cutting edge in AC tech., materials, smart home tech., communication with customer—customer service in general. Everyone was on the same page with that. As of May 2022, this is a company that seems to be in a good place doing good business. I prioritize capability over “nice gals/guys,” but worth mentioning that they have people skills. Especially young guy that assessed and did sales end—really bright. So, this is genuine, I feel like they went far enough to be worth my time writing a review. Recommended.
