Your furnace just broke and your house is getting cold. Here's your action plan: what to do right now, what repairs typically cost, and how to pay if money is tight.
It’s cold. The furnace isn’t responding. Your family is watching you figure this out.
Here’s your plan.
60-Second Plan
Check these 3 things first: Thermostat set to heat? Breaker tripped? Filter clogged? These fix most “emergencies” for free.
Cost reality: Most repairs run $125–$480. Emergency/after-hours service doubles or triples that.
Can’t pay today? You can split the bill into 4 payments with Deferit, use HVAC financing, or check if LIHEAP can help.
↑ TopWhat Will This Cost?
Most people don’t realize how fast emergency rates stack up—what would cost $150 on a Tuesday afternoon can hit $400+ on a Saturday night[1]:
| Repair Type | Business Hours | Emergency/After-Hours |
|---|---|---|
| Minor (ignitor, thermostat, filter issue) | $100–$300 | $200–$450 |
| Standard (blower motor, gas valve, control board) | $300–$600 | $450–$900 |
| Major (heat exchanger, inducer motor) | $600–$1,500+ | $900–$2,200+ |
Why emergency service costs more: HVAC techs charge 2–3x their normal labor rate for nights, weekends, and holidays[2]. Emergency labor rates typically range from $140–$210 per hour on the low end to $400–$600 per hour on the high end[3]. That $150 repair during business hours could hit $400+ at 2am on Saturday.
Service call fees: Most companies charge $75–$200 just to show up and diagnose the problem[2]. This fee usually gets applied to your repair if you proceed, so ask before they arrive.
If you’re quoted over $1,500 and your furnace is 12+ years old, get replacement quotes too.
↑ TopCan’t Pay the Full Bill Right Now?
A broken furnace doesn’t wait for payday. Here are your options:
- Deferit – Split your furnace repair bill into 4 payments over 8 weeks. We pay your repair bill directly, you pay us back over time. No credit check.
- HVAC Company Financing – Many contractors offer 0% promotional financing for 6–12 months. Ask before they start work.
- LIHEAP – This federal program can help with emergency furnace repairs for qualifying households[4]. Contact your state’s LIHEAP office or call 211 for local assistance.
- Home Warranty – If you have one, check if furnace repair is covered before authorizing work. You may only owe a service call fee.
- Credit Card – An option, but watch the interest. Only use this if you can pay it off quickly or have a 0% intro APR card.

↑ TopBefore You Call Anyone
Smell gas? Leave immediately and call your utility company’s emergency line from outside. Don’t flip switches or light anything.
No gas smell? Run through this checklist before paying for a service call:
- Thermostat set to “heat” mode (not “cool” or “off”)?
- Thermostat batteries fresh? Dead batteries are the #1 surprise fix
- Breaker tripped? Flip furnace circuit off, then on
- Furnace power switch on? (Looks like a light switch near the unit)
- Filter clogged? A gray, thick filter can trigger the safety shutoff. Replace and wait 30 minutes
- Pilot light out? (Older gas furnaces only)
- Try a full power cycle: thermostat off → breaker off → wait 60 seconds → breaker on → thermostat on
If these don’t work, call an HVAC company. Ask about their emergency service fee upfront—reputable companies will tell you before they dispatch.
While you wait: Space heaters can keep one room livable. Layer up and close off unused rooms to conserve heat.
↑ TopShould You Repair or Replace?
The 50% rule makes this decision simple[5]:
If the repair costs more than 50% of a new furnace AND your furnace is 12+ years old, replacement usually makes more financial sense.
New furnace cost benchmark: $3,500–$7,500+ installed[6], depending on efficiency and home size.
Example: Your 15-year-old furnace needs a $1,800 heat exchanger repair. That’s more than 50% of a $3,500 mid-range replacement. You’d be putting major money into an aging system that could fail again soon.
When repair makes sense:
- Furnace is under 10 years old
- Repair is under $500
- This is the first major repair
- You can’t swing replacement costs right now (repair buys you time)
Tax credit note: The federal Energy Efficient Home Improvement Credit (25C) can cover up to $600 toward a new high-efficiency furnace[7], plus many utilities offer $200–$1,000 in rebates. This credit is available through December 31, 2025.
Red flags to watch for:
- Demanding full payment before any work
- Pressuring you to replace when repair is viable
- Refusing to explain the diagnosis
- Cash-only payment requirements
↑ TopPrevent the Next Emergency
Once you’re warm again, protect yourself from a repeat:
- Annual maintenance: Schedule a tune-up before heating season (September–October). Technicians catch problems when they’re small.
- Change your filter: Every 1–3 months during heavy use. Set a phone reminder.
- Know the warning signs: Strange noises, weak airflow, frequent cycling, and higher-than-normal bills mean something’s wrong. Address it before it becomes an emergency.
↑ TopNext Steps
You know what to check, what repairs cost, and how to handle the bill. Start with the free fixes. If you need a technician, get costs in writing before they start work. If the bill is more than you can cover right now, see the payment options above.
