What Should I Do If My Heater Is Not Working in My House?

Start with safe checks, then call us if it still won’t run. We service furnaces, boilers, heat pumps, and radiant systems in Franklin, MA and nearby. Try these quick steps:

  • Set thermostat to Heat and raise the setpoint.
  • Make sure the furnace/power switch is on and check the breaker.
  • Replace a clogged filter and open supply/return vents.

What Is the Average Furnace Maintenance Cost for Homeowners?

There isn’t a single “average” furnace maintenance cost because pricing depends on your system type (gas, oil, electric), condition, and the tune-up scope. We provide transparent, upfront pricing after a quick assessment, so Franklin and nearby homeowners know the cost before work begins. You can bundle annual service with our Priority Plan for front-of-the-line service and extended 4-year warranties on work. Promotions may apply, such as a free system check-up with a maintenance agreement.

What a tune-up typically includes:

  • Inspect and clean the burner.
  • Inspect the heat exchanger for carbon monoxide risks.
  • Replace the air filter.

What Does Furnace Replacement Cost for Most Homeowners?

Furnace replacement cost is finalized only after an in‑home evaluation of your system and home. Most of the price comes from matching the right equipment and doing a safe, code‑compliant installation rather than the furnace alone. If the heat exchanger is cracked or repairs keep stacking up, replacement is usually smarter than another patch. Our team regularly replaces systems in the Dorchester area and accounts for New England home layouts and weather when sizing. Ask about our current $600 OFF heating and cooling system replacement promotion.

Key cost drivers typically include:

  • Equipment type and efficiency rating, and the capacity needed for your home
  • Fuel type (gas, oil, electric) and any conversion or venting changes
  • Installation scope: ductwork or radiator tie‑ins, gas/oil/electrical, condensate and flue work
  • Add‑ons like smart thermostats, zoning, or indoor air quality upgrades

To get a firm, transparent price, schedule an on‑site assessment so we can size the system correctly and detail the full install scope.

What Are Common Reasons My Heater Is Not Working in My House?

Most heater failures at home come from thermostat settings, lost power, dirty filters/burners, or fuel/ignition issues. We service furnaces, boilers, heat pumps, and ductless systems, and provide fast repairs.

  • Set thermostat to Heat and raise 3–5°F.
  • Replace a dirty filter.
  • Verify the furnace switch and breaker are on.
  • Confirm gas or oil supply and the gas valve is open.
  • Clear outdoor intake/exhaust vents. If you smell gas, exit and contact your utility. Every repair includes a 2-year warranty (4 years for Priority Plan members). Service available in Holbrook and nearby.

How much does residential heating maintenance typically cost?

Residential heating maintenance cost is confirmed after an on-site visit because pricing depends on your system and the work included. The biggest driver is system type and condition, since boilers, furnaces, and heat pumps need different checks and cleaning steps. Annual service typically covers safety and performance inspections, cleaning, and adjustments to cut energy waste and catch hazards early. Our technicians service homes throughout the Bellingham area with a documented checklist and straightforward, upfront pricing. G&C Plumbing & Heating also offers a Priority Plan with annual maintenance, priority scheduling, and extended 4-year warranties on work for members.

Price varies by these common factors:

  • System type and fuel (boiler, furnace, heat pump; gas, oil, electric)
  • Number of zones or units that require service
  • Access and cleanliness of equipment and venting
  • Add-ons requested, like filter changes or deeper cleaning

Schedule is best in early fall so any needed parts or repairs don’t delay heat when cold hits.
