A furnace that stops in January is more than an annoyance. In the Newton area, cold snowy winters push heating systems hard, and older homes lose warmth quickly. Name the problem, note the season, and pick the next step.
Paperforth Heating & Air is a referral service. We do not do the repair. We connect you with an independent provider in our network who diagnoses the fault, explains it plainly, and gives a written quote. This page covers safety first, quick checks, common failures, and the repair-or-replace decision. It also shows how to gather photos and notes so your estimate goes faster.
Smell Gas? Leave the House First
A rotten-egg smell means gas. Do not flip switches, use a lighter, or try to restart the furnace. Walk outside. Call 911 or your gas utility from there, and stay out until you are cleared to return.
Carbon Monoxide Warning Signs
Headaches, dizziness, nausea, or a sounding CO alarm can point to a venting fault. Get everyone outside into fresh air. Keep the furnace off until a provider has inspected it.
Season First, Then Service
Furnaces fail when they work hardest. A heat loss on a bitter night in an older home is urgent, because the house cools fast. Name the problem, note the indoor temperature, and move to the next step.

Quick Checks Before You Request a Provider
Spend five minutes on these. They solve more heating calls than most people expect.
- Thermostat set to heat, with fresh batteries.
- Breaker on, and the furnace switch on (it looks like a light switch).
- Air filter clean. A clogged one can trip safety limits.
- Gas valve open and the igniter or pilot showing signs of life.
- Vents and return grilles clear of boxes and furniture.
Basement and Utility Room Check
Many local homes have full basements with stone or block foundations. Look for standing water near the unit, a stuck condensate pump, or a blocked flue pipe. Spring snowmelt can seep in through those walls. Keep the area dry and note what you see.
Common Signs Your Furnace Needs Repair
Look for patterns, not one-off quirks.
- Banging, squealing, or rattling at startup
- A yellow burner flame instead of blue
- Short cycling: starting and stopping every few minutes
- Cold rooms next to warm ones
- Rising bills with no change in habits
- An igniter or pilot that keeps failing
What the Noises Usually Mean
Banging often means delayed ignition. Squealing suggests a worn blower belt or motor bearing. The blower is the fan that pushes warm air through the ducts. Grinding means stop using the furnace and request a provider.
Paperwork-Ready: Photos Before Estimates
Photograph the model plate, the error code on the control board, and any rust, soot, or water. Write down when the trouble began and what you tried. Providers can quote faster and more accurately with this.
Records Worth Pulling Together
- Past service invoices
- Filter change dates
- Approximate furnace age
- Warranty papers, if you have them
What Happens During a Furnace Repair Visit
The provider listens to your description first. Then they check the thermostat and power, and inspect the igniter, flame sensor, blower, heat exchanger, and venting. They test safety controls and carbon monoxide levels. You should get a plain explanation and a written quote before work starts.
Parts and Timing
Igniters, sensors, and capacitors are common parts. Providers often carry them. Specialty parts may take a few days. Ask what the plan is while you wait.
Common Furnace Repairs
- Igniter or flame sensor: the furnace tries to start, then shuts down.
- Blower motor or capacitor: weak airflow or a humming sound.
- Inducer motor or pressure switch: the unit will not complete its start cycle.
- Thermostat or control board: wrong temperatures or no response.
- Condensate drain: clogs shut down high-efficiency models.
- Cracked heat exchanger: a safety issue that often starts a replacement talk.
Cold Snaps, Snowmelt and Coastal Storms
Heavy snow can block outdoor intake and exhaust pipes on high-efficiency furnaces. Clear them gently by hand. Coastal storms bring outages and power surges, and a surge can damage a control board. Damp springs add rust and humidity in basements. A fall tune-up beats a January breakdown.
Insurance and Documentation
Some policies may cover sudden damage, such as a power surge. Wear and tear is usually excluded, so check your policy. Providers can often help document damage for a claim. Keep photos, invoices, and notes in one folder.
Repair or Replace Your Furnace?
These signs push the answer toward replacement:
- The furnace is roughly 15 to 20 years old.
- A repair costs close to half the price of a new unit.
- The heat exchanger is cracked.
- Repairs keep coming back.
- Heating bills keep climbing.
If you are searching for furnace replacement near me, ask the provider for a repair quote and a replacement quote side by side. Compare them in writing.
Questions to Ask the Provider
- What is the fault, and can you show me the part?
- Is the quote written, with parts and labor listed?
- Is the repair warrantied, and for how long?
- Is the unit safe to run today?
- Do you also handle HVAC service for the rest of the heating and cooling system?
Summer Cooling Is a Different Job
If the trouble is warm air in July, that is emergency AC repair territory. It has its own page and its own checklist.

No obligationHome Furnace Repair FAQ
Why is my furnace running but not heating my house?
Common causes include a dirty filter, a failed igniter or flame sensor, a weak blower, or a thermostat problem. Try the quick checks first. If the issue stays, request a provider to diagnose it.
Is it safe to use a space heater while waiting for furnace repair?
Use only a heater approved for indoor use. Plug it straight into the wall and keep it away from curtains and bedding. Never use a gas oven or grill for heat.
How do I know if I need furnace repair or furnace replacement?
Age, repair cost, safety, and frequency all matter. A unit near 15 to 20 years old with repeat breakdowns or a cracked heat exchanger may call for replacement. Ask for both quotes.
