Most HVAC repairs in the USA cost between $200 and $850 in 2026. Thumbtack puts the national average HVAC repair cost at $191 to $842, with small jobs starting near $64 and major repairs reaching about $2,600 or more.
Where you land in that range depends on what broke, the type of system you have, how old it is, and where you live. Below you’ll find real price ranges for the most common AC, furnace and heat pump repairs, plus what to ask your technician so you don’t overpay.
Quick definition: HVAC stands for heating, ventilation and air conditioning. It covers your central air conditioner, furnace, heat pump, ductwork and thermostat.
What is the average HVAC repair cost in 2026?
The average HVAC repair cost in the USA is roughly $200 to $850, and most homeowners pay around $350 to $500 for a typical fix. Simple jobs like a capacitor or thermostat cost $150 to $400. Major part failures, such as a compressor or heat exchanger, can cost $1,500 to $4,500.
Your final bill is usually made of three parts: a service call or diagnostic fee, the cost of the part, and labor. Labor is often the biggest piece. Many technicians charge $75 to $150 per hour, and some markets run higher.
| Cost Item | Typical 2026 Price | Notes |
|---|---|---|
| Service call or diagnostic fee | $70 to $200 | Often credited toward the repair if you approve it |
| Labor | $75 to $150 per hour | Higher in big cities and during peak season |
| Minor repair (total) | $150 to $450 | Capacitor, contactor, thermostat, igniter, clogged drain |
| Mid range repair (total) | $450 to $1,200 | Blower motor, refrigerant leak, inducer motor |
| Major repair (total) | $1,500 to $4,500 | Compressor, evaporator coil, heat exchanger |
| Emergency or after hours surcharge | $150 to $500 extra | Nights, weekends and holidays |
How much does AC repair cost?
Most central AC repairs cost $150 to $650, with a national average around $350. A failed capacitor is the most common and cheapest fix at $150 to $400. A refrigerant leak can run $200 to $1,500, and a new compressor is the priciest AC repair at $1,000 to $3,500 or more.
If your AC is blowing warm air, the problem is often an electrical part in the outdoor unit. That’s good news, because those parts are inexpensive. The capacitor itself may cost under $50, so most of the bill is the technician’s time.
Common AC repair costs
| AC Repair | Typical Cost (Parts and Labor) | Common Sign |
|---|---|---|
| Capacitor replacement | $150 to $400 | Outdoor unit hums but the fan won’t spin |
| Contactor replacement | $120 to $450 | Unit won’t turn on or won’t shut off |
| Clogged condensate drain line | $75 to $250 | Water around the indoor unit |
| Thermostat replacement | $80 to $350 | System won’t respond to settings |
| Refrigerant recharge (R410A) | $150 to $900 | Weak cooling, ice on lines |
| Refrigerant leak find and repair | $200 to $1,500 | Cooling fades again after a recharge |
| Fan motor replacement | $300 to $700 [VERIFY] | Outdoor fan is noisy or stopped |
| Evaporator coil repair or replacement | $500 to $3,500 | Repeated leaks, poor cooling |
| Compressor replacement | $1,000 to $3,500+ | Loud clanking, breaker trips, no cooling |
Why refrigerant repairs can get expensive
Refrigerant is the chemical that carries heat out of your home. If your system needs a recharge, it almost always has a leak, because refrigerant doesn’t get “used up.” A good technician will find and fix the leak instead of just topping it off.
Older systems that use R22 (often called Freon) cost much more to service. R22 was phased out of production in the US in 2020, so remaining supply is scarce and pricey. If an R22 system has a major leak, replacement is often the smarter choice.
How much does furnace repair cost?
Most furnace repairs cost $150 to $600, and HomeAdvisor reports a typical bill of about $318. Small parts like an igniter or flame sensor cost $120 to $300 installed. A blower motor runs $300 to $1,200, while a cracked heat exchanger is the most expensive furnace repair at $1,000 to $4,500.
Furnace problems often show up on the first cold night of the year, which is also when HVAC companies get busiest. Scheduling a tune up in early fall can catch a weak igniter before it leaves you without heat.
Common furnace repair costs
| Furnace Repair | Typical Cost (Parts and Labor) | Common Sign |
|---|---|---|
| Flame sensor cleaning or replacement | $80 to $250 | Burners light, then shut off within seconds |
| Igniter replacement | $120 to $300 | Furnace clicks but never lights |
| Thermostat replacement | $80 to $350 | Heat won’t kick on |
| Draft inducer motor | $200 to $1,500 | Humming or rattling before startup |
| Control board replacement | $300 to $900 [VERIFY] | Blinking error codes, erratic cycling |
| Blower motor repair or replacement | $300 to $1,200 | Weak airflow or squealing noise |
| Heat exchanger replacement | $1,000 to $4,500 | Cracks, soot, carbon monoxide alarm |
Is a cracked heat exchanger dangerous?
Yes. A cracked heat exchanger can leak carbon monoxide, a gas you can’t see or smell, into your home. If a technician finds a crack, turn the furnace off and don’t run it until it’s fixed. Because this repair is so costly, many pros recommend replacing an older furnace instead.
Make sure you have working carbon monoxide detectors on every floor. If one goes off, leave the house and call 911 or your gas company.
How much does heat pump repair cost?
Heat pump repairs usually cost $465 to $2,400, with a typical bill near $1,000. Heat pumps run all year for both heating and cooling, so they tend to wear faster than a standalone AC. Small part fixes stay under $500, but compressor and reversing valve problems push the total much higher.
A heat pump is a system that moves heat instead of making it. In summer it pulls heat out of your home, and in winter it pulls heat in from outside air. Repairs often mirror AC repairs (capacitors, contactors, refrigerant leaks), plus heating specific parts like the reversing valve and defrost controls.
What affects the cost of HVAC repair?
Five things drive most HVAC repair costs: the part that failed, your system type, its age, local labor rates and when you call. A capacitor swap on a weekday in a small town costs far less than a compressor replacement on a Saturday night in a major city.
- The failed part. This is the biggest factor. A $20 capacitor and a $1,500 compressor lead to very different bills.
- System type. Oil and propane furnaces cost more to repair than electric ones because parts are less standard and fewer techs work on them. High efficiency furnaces have extra parts that can raise the bill.
- Age and warranty. If a part is still under the manufacturer’s warranty, you may pay only for labor. Older units need more frequent and costlier repairs.
- Your location. Labor rates vary a lot by region. As one example, a blower motor job that costs about $380 to $520 in the Midwest can run $480 to $700 on the West Coast. Rural homes may also pay a travel fee.
- Timing. Peak summer and winter weeks bring higher demand. Night, weekend and holiday calls usually add $150 to $500.
How much is an emergency HVAC repair?
An emergency HVAC repair usually costs the normal repair price plus an after hours fee of $150 to $500. Some companies charge a higher flat service call instead, often $150 to $300 just to show up. Ask about the emergency rate on the phone before the technician drives out.
Not every breakdown is a true emergency. If it’s mild outside and nobody in the home is elderly, an infant or medically at risk, waiting until regular hours can save you a few hundred dollars. If temperatures are dangerous, call right away.
When you need someone fast, you can compare local HVAC companies on Search Acharya to see who’s open now, read reviews and call directly.
Should you repair or replace your HVAC system?
Replace your HVAC system if the repair costs more than half the price of a new one, or if the unit is over 10 to 15 years old and breaking down often. Repair it if the system is under 10 years old, the fix is a small part, and it has been reliable so far.
Two quick rules help you decide:
- The 50 percent rule. If the repair quote is more than 50 percent of the cost of a new system, replacement usually makes more sense.
- The $5,000 rule. Multiply the age of your unit by the repair cost. If the number is over $5,000, lean toward replacing. For example, a 12 year old AC with a $600 repair gives you $7,200, so replacement is worth pricing out.
For context, a new central HVAC system typically costs about $4,800 to $15,000 for equipment alone, and installation, ductwork and permits add more. A new heat pump installed often runs $4,500 to $12,000. Get at least two written quotes before you decide.
How can you lower your HVAC repair cost?
The cheapest HVAC repair is the one you prevent. A yearly tune up costs $100 to $200 and catches worn parts early. Beyond that, compare quotes, ask about warranties and handle the simple checks yourself before you call a pro.
Check these before you call
- Make sure the thermostat is set to heat or cool and has fresh batteries.
- Check your breaker panel for a tripped breaker.
- Replace a dirty air filter. A clogged filter causes weak airflow and frozen coils.
- Look at the outdoor unit and clear away leaves, grass and debris.
- Check that the furnace switch (it looks like a light switch) is on.
Questions to ask your HVAC technician
- What is your service call fee, and does it go toward the repair?
- Is the part covered under the manufacturer’s warranty?
- Can you give me a written estimate with parts and labor listed separately?
- Do you guarantee your labor, and for how long?
- Are you licensed and insured in this state?
Red flags to watch for
- A tech who recommends full replacement without explaining what failed.
- Pressure to decide on the spot with a “today only” price.
- Repeated refrigerant top offs with no attempt to find the leak.
- No written estimate or no license number on request.
Licensing rules for HVAC contractors differ by state, and work on refrigerant requires EPA Section 608 certification. Ask for proof if you’re unsure.
When should you call a pro instead of doing it yourself?
Call a licensed HVAC technician for anything involving refrigerant, gas lines, electrical parts inside the unit or a carbon monoxide concern. DIY is fine for filters, thermostat batteries, clearing the outdoor unit and flushing a clogged drain line with vinegar. Capacitors can hold a dangerous charge even when the power is off.

Frequently Asked Questions
How much does an HVAC technician charge per hour?
Most HVAC technicians charge $75 to $150 per hour in 2026. Rates are higher in large cities, during peak heating and cooling seasons, and for after hours calls. Many companies also charge a flat service call fee of $70 to $200 on top of hourly labor.
Is the HVAC diagnostic fee applied to the repair?
Often, yes. Many companies credit the diagnostic fee toward the final bill if you approve the repair. Others charge it separately no matter what. Always ask on the phone before booking so there are no surprises.
What is the most expensive HVAC repair?
Compressor replacement and heat exchanger replacement are the most expensive HVAC repairs. A compressor usually costs $1,000 to $3,500 or more, and a heat exchanger can run $1,000 to $4,500. On older systems, these repairs often make replacement the better value.
How much does it cost to fix an AC that’s blowing warm air?
Fixing an AC that’s blowing warm air usually costs $150 to $650. The cause is often a bad capacitor, a dirty filter or low refrigerant from a leak. If the compressor has failed, the cost jumps to $1,000 or more.
Does a home warranty cover HVAC repairs?
Many home warranty plans cover HVAC repairs, but you’ll still pay a service fee per visit, usually set in your contract. Coverage limits and exclusions vary widely, so read your plan carefully. Manufacturer warranties on parts are separate and often last 5 to 10 years with registration.
How often should I service my HVAC system?
Service your HVAC system once a year, or twice a year if you have a heat pump, since it runs in both seasons. A tune up costs about $100 to $200. Schedule cooling service in spring and heating service in early fall.
How long does an HVAC repair take?
Most simple HVAC repairs, like a capacitor or igniter, take 30 minutes to 2 hours. A blower motor takes 2 to 4 hours. Big jobs like a compressor or heat exchanger can take 4 to 12 hours and may require ordering parts.
