Heating Problems We Fix
When your heat goes out, you need fast, reliable help. We repair furnaces, boilers, and home heating systems across Spencer and surrounding towns—so you’re not left in the cold.
No Heat or Cold Air Blowing
If your system runs but your home isn’t warming up, we’ll check your ignitor, pilot light, thermostat, or fuel supply. We get to the source and fix it—fast.
Uneven Heating or Cold Rooms
Some rooms too hot, others too cold? We balance airflow, check for blockages, and adjust your system to heat your home evenly.
Strange Noises or Smells
Rattling, banging, or squealing sounds could mean failing parts. Burning smells or fuel odors are safety issues—we’ll identify and resolve them immediately.
Short Cycling or Constant Running
If your furnace or boiler keeps turning on and off—or never shuts off—it’s wasting fuel and wearing down your system. We’ll tune it to run efficiently and properly.
Pilot Light or Ignition Problems
If your gas system won’t light or stay lit, we check components like the flame sensor, thermocouple, or control board. Our repairs are thorough and safe.
Boiler & Radiator Issues
We fix hot water and steam boilers common in older Worcester County homes. Whether it’s air in the lines, low pressure, or no heat in your radiators, we’ve seen it before and we fix it right.

Heating Repair Questions? We’ve Got Answers.
What should I check before calling for heat repair?
Make sure the thermostat is set to “heat,” the system has power, and your furnace filter is clean. If it still doesn’t run or blows cold air, give us a call.
Do you repair both furnaces and boilers?
Yes. We work on gas furnaces, oil furnaces, steam boilers, and hot water boilers. We’re familiar with the older systems common in this area.
Can you help with baseboard or radiator heat?
Absolutely. We repair hydronic heating systems, including baseboards and radiators. Whether it’s an airlock or bad circulator, we’ll get the heat flowing again.
Is a noisy furnace a problem?
Yes. Banging, squealing, or rumbling often means a part is loose, dirty, or failing. We’ll figure it out and fix it before it causes more damage.
How fast can you respond during cold weather?
We prioritize no-heat calls during cold snaps. In many cases, we offer same-day service throughout Worcester County.
Do you carry common replacement parts?
Yes. Our trucks are stocked with many of the most common parts for repairs. If we need to order something, we’ll get it fast and keep you in the loop.
Can I do anything to avoid future heating problems?
Regular maintenance and changing your filters go a long way. We also recommend annual service to catch wear before it becomes a breakdown.
