Heating Repair: one call, routed to a local contractor
Whatever heats your home — furnace, boiler, heat pump, or electric strips — one call routes you to an independent local contractor registered for heating work in your ZIP code. You describe the symptom; ask the contractor for its diagnostic fee and schedule. This is a referral line, not the contractor: ask the fee and whether it credits toward the repair before you book. After-hours routing is on record in the markets where a contractor registered for it.
What does heating repair involve?
Heating repair covers furnaces, boilers, heat pumps in heating mode and electric resistance heat. Tell the contractor which system you have and what it is doing (no heat, short cycling, a tripped breaker, ice on a heat pump, a boiler losing pressure) so the call reaches someone equipped for it.
Any fuel-burning heater shares the same rule: a carbon monoxide alarm on every level of the home and outside sleeping areas (CPSC; NFPA), and an annual inspection and cleaning of the heating system and chimney before the season (NFPA), are the layers of protection that do not depend on the equipment working.

When is heating repair an emergency — and what comes before any call?
- If a carbon monoxide alarm sounds, or anyone has CO symptoms (headache, dizziness, weakness, nausea, vomiting, sleepiness, confusion): get everyone outside to fresh air immediately, then call 911 from outside and stay out until emergency personnel say it is clear (CPSC; NFPA). If you smell gas: leave the area on foot immediately without trying to find the source, do not operate switches, phones or anything that could ignite it on the way out, and call 911 from a safe location, then the gas company (PHMSA). The HVAC visit comes after the all-clear.
- Smoke or flames from the equipment: get everyone out, go to your outside meeting place and stay there, and call the fire department from there (USFA). A burning or electrical smell without smoke: say so when you call and ask for the earliest visit.
- No heat with freezing temperatures outside is urgent for the house as well as the people in it; say so plainly when you call and ask for the earliest visit.
What the symptom usually means
Some rooms heat, others stay cold
Balancing problems, closed or crushed ducts, air-bound radiators on hydronic systems, or a zone valve that quit.
Heat pump runs constantly but the house will not reach setpoint
Low refrigerant, a failed reversing valve, or auxiliary heat not engaging when outdoor temperatures drop.
Boiler pressure keeps dropping or relief valve drips
A leak somewhere in the loop, a waterlogged expansion tank, or a failing fill valve — all fixable, none ignorable.
Electric heat smells hot or trips the breaker
Sequencer or element faults in electric furnaces and air handlers; breaker trips deserve immediate attention.
Banging or gurgling pipes on hydronic heat
Trapped air, sediment kettling in the boiler, or condensate return problems on steam systems.
How the call works
-
Describe what the heat is doing
Dead thermostat, cold air from the vents, a system that tries to start and gives up — thirty seconds of description is enough to route you correctly.
-
Your ZIP routes to a heating contractor
Your call routes to an independent contractor registered for heating work at your address. Ask whether it works on your system type — gas, electric, oil, or heat pump.
-
Ask the fee before the truck rolls
Ask the contractor for its diagnostic fee on the phone, and for any after-hours premium. If the answer does not work for you, the call has cost you nothing.
-
Diagnosis, price, your decision
Ask to see the failed part and the repair price, and — on older equipment — for the repair-versus-replace math in writing. Proceed or collect another bid; the choice stays yours.
This is a referral line. The contractor who answers is an independent business that registered its routing category for your ZIP code in the data dated July 12, 2026; it sets its own fees, schedule and availability, and may pay this site a referral fee if it accepts the call.
How heating repair pricing works here
Every contractor in this network sets its own pricing — this site never marks it up, never quotes it, and takes no part in the visit. What this page can do is tell you what to ask, on the phone, before you agree to a visit:
| Ask | When | Why it matters |
|---|---|---|
| What is the diagnostic fee, and does it credit toward the repair? | On the phone, before booking | So the visit price is known before a truck rolls |
| Will you show me the failed part and its readings? | During the visit | A diagnosis you can see beats one you are told |
| Can I have the quote in writing before work begins? | Before authorizing | Yours to keep and shop — comparison is normal |
| What is the after-hours premium, and are parts at standard prices? | When you book | Night and weekend rates are the contractor’s to state — ask before you commit |
Want national planning figures first? The editorial cost guides itemize each job line by line — research content, kept separate from this routing service.
When this becomes a right-now call
Many heating repair calls are urgent without being emergencies — and knowing the difference is worth real money. If a carbon monoxide alarm sounds or you smell gas, the evacuation steps at the top of this page come first. Beyond that, genuine emergencies are about safety, not comfort: no heat below freezing with the pipe-damage clock running, or anything that smells electrical (say so when you call; smoke or flames mean everyone out and the fire department first). Those justify the after-hours call without hesitation. Whether the after-hours category is on record for your ZIP code in the data dated July 12, 2026 is what the lookup below shows; ask the after-hours premium before booking.
Everything else — a failure in mild weather, weakening output, a strange new noise — can usually wait for a daytime visit; ask whether it carries a lower fee than an after-hours one, because the contractor sets both. The triage takes ten seconds of honesty about what's actually at risk tonight.
Repair or replace — what should a contractor put in front of you?
There is no published age at which a repair stops making sense. ENERGY STAR’s guidance is that equipment more than 10 years old, or not keeping the house comfortable, should be evaluated by a professional HVAC contractor (Heat & Cool Efficiently, read 2026-09-10); what that evaluation should produce is a repair quote and a replacement quote side by side, so the decision is yours and made on numbers.
Three findings are the ones to ask about explicitly: a compromised heat exchanger on a furnace, a compressor-grade fault on a heat pump, and a sealed-system repair on equipment running R-22 (the EPA states no new R-22 has been made or imported since 2020 and that owners are not required to replace their equipment — reclaimed supply continues, at whatever price the contractor quotes). Ask for the failed part and its readings anywhere, and for both quotes in writing; then compare them against any other bidder.
How do you compare written proposals for heating repair?
Ask every bidder for the same things, in writing, so the proposals can be laid side by side:
- The system type named correctly on the quote (boiler, furnace, heat pump, electric), and the failed component with its reading.
- For boilers: pressure, expansion tank and relief-valve findings written down; for heat pumps: defrost and refrigerant findings, and the EPA 608 card if refrigerant was handled.
- Whether the diagnostic fee credits toward the repair.
- The company’s legal name, license number (where the state licenses this work) and insurance certificate on the document — then check the number in the state lookup.
- Model numbers for every major component, with the certified ratings you can look up yourself in the AHRI Certification Directory (Directory of Certified Product Performance).

Is this the right guide for your heating problem?
Heating repair here means whole-home heating beyond the furnace: boilers and radiators, heat pumps in heating mode, electric resistance and hybrid systems. Two system types have their own guides with the questions specific to them.
- Gas or oil furnace
Forced air; burners light; ignition, flame-sensor, limit and heat-exchanger questions.
Furnace repair guide → - Heat pump
The outdoor unit runs in winter; defrost, auxiliary-heat and capacity-at-temperature questions.
Heat pump services guide → - Boiler, radiators, electric or hybrid heat
This guide. The symptoms and questions on this page are written for those systems.

Prepare the heating repair call: turn your symptom into questions
Nothing here diagnoses your system or prices a repair. It turns what you know — age, symptom, refrigerant if you know it, whether anyone has looked at it — into the questions worth asking the contractor who answers.
Before you call about heating repair: what to have ready and what to ask
The result is a list of questions for the contractor, not a diagnosis and not a price.

Terms your contractor will use on this job
Heat Exchanger
A furnace’s heat exchanger is the sealed metal assembly that keeps combustion separate from your household air. Burner flames heat it from inside; the blower pushes house air across its outside, picking up heat without ever touching exhaust gases. Those gases — including carbon monoxide — exit through the flue.
Short-Cycling
Short-cycling is when heating or cooling equipment starts, runs briefly, shuts down, and repeats — cycles of a few minutes instead of steady runs. It multiplies the most damaging event in an equipment’s life (the start), degrades comfort and humidity control, and inflates energy use.
Thermostat
The thermostat is the control that reads room temperature and commands the HVAC equipment: calling for heat, cooling, or fan, and — on multi-stage or heat-pump systems — deciding which stage or backup source runs. Smart thermostats add scheduling, occupancy learning, and remote control, and typically require a C-wire for continuous power.
Balance Point
A heat pump’s balance point is the outdoor temperature at which its heating output exactly equals the house’s heat loss. Above it, the heat pump carries the load alone; below it, backup heat — electric strips or a furnace — must make up the difference. Typical balance points fall between 25 and 40°F depending on equipment capacity and the house envelope.
Thermocouple
A thermocouple is the flame-safety device on older standing-pilot furnaces and water heaters: a probe sitting in the pilot flame generates a tiny voltage that holds the pilot gas valve open. If the pilot goes out, the voltage dies and the valve snaps shut — gas cannot flow unburned. Modern furnaces replaced the pair with electronic ignition and flame sensors.

What to ask any heating repair contractor — from this line or anywhere
Which license, and where can I check it?
Every contractor this line routes to is an independent business responsible for its own licensing. Ask for the license number on the estimate; each city page on this site carries the state's own wording and lookup where one has been verified.
What is the fee, and does it credit?
Ask the diagnostic cost, whether it credits toward a repair, and any after-hours premium — on the phone, before a truck rolls. This site sets no prices and cannot promise what a contractor will say.
Can I see the diagnosis?
Ask for the failed part and its readings, and on aging equipment ask for the repair-versus-replace conversation with the numbers attached.
Can I have that in writing?
Ask for the quote in writing before work begins. Comparing it against any competitor is your right.
Federal rule, every state: under Clean Air Act Section 608, “technicians who maintain, service, repair, or dispose of equipment that could release ozone depleting refrigerants into the atmosphere must be certified.” Ask to see the technician’s EPA 608 card when refrigerant is handled.

My heat pump is blowing cool-ish air in winter — is it broken?
Not necessarily. Heat pump supply air is noticeably cooler than a gas furnace’s, so it can feel underwhelming when outdoor temperatures drop even while the house holds temperature. It is a problem if the house cannot hold setpoint, if the unit ices over past a normal defrost cycle, or if your backup heat runs constantly — those are service calls.
Why does my boiler need water added every week?
A sealed hydronic loop should not lose pressure. Weekly top-ups mean water is leaving somewhere: a pinhole in the piping, a weeping relief valve, a failed expansion tank bladder, or on steam systems, a leaking return. Constant fresh water also brings constant fresh oxygen and minerals, which corrode the boiler from the inside — get the leak found.
What does it mean when only half the house gets warm?
On forced-air systems, look at ductwork first: crushed flex duct, a closed damper, or leaks feeding your attic instead of the back bedrooms. On hydronic systems it is usually air trapped in the loop or a dead zone valve or circulator. The fix is often modest; running the thermostat higher to compensate is the expensive non-fix.
When is auxiliary or emergency heat supposed to run?
Auxiliary heat engages automatically when the heat pump alone cannot keep up — typically during deep cold or recovery from a setback. Emergency heat is the manual switch that abandons the heat pump entirely. If aux heat runs during mild weather, or your utility bill doubles, the changeover controls or the heat pump itself need attention.
Are space heaters a safe stopgap while I wait for repair?
If you use one, follow the National Fire Protection Association’s heating-equipment page, which stresses keeping space heaters at least 3 feet away from anything that can burn (NFPA, “Safety with heating equipment”, read 2026-09-11). Read the heater’s own manual for its placement and power rules; this site adds nothing to either. A carbon monoxide alarm or a gas smell means everyone outside and a 911 call first.

Featured heating repair coverage
Contractor coverage is ZIP-code based. As of the routing data dated July 12, 2026, 2,892 named markets had this category on record; these are among them:
Both paths end at the same questions
Some homeowners want the full picture before dialing — for them, the itemized cost guides, the troubleshooting library, and the glossary exist so a heating repair conversation can be had fluently. The number at the top of this page routes to an independent contractor whose fee and schedule you should ask about before booking. Neither path is wrong.
What we'd gently insist on either way: describe the symptom precisely (this page's symptom section gives you the vocabulary), ask the contractor to show you the diagnosis before authorizing work, and keep the written quote — comparison is your right.
