2026 component pricing
HVAC part replacement costs
A technician names a part, and you have about a minute to decide whether the number attached to it is fair. Each page below prices one component with a researched 2026 range, the symptoms that point to it, and the cheaper fault it is commonly confused with.
By the HeatAndAirCost editors · Last updated September 14, 2026 · How we research prices
| Part | Typical 2026 range | Notes |
|---|---|---|
| Capacitor | $250–$400 | Cheapest common failure on both furnaces and air conditioners. |
| Furnace pressure switch | $150–$400 | Often a blocked vent or drain rather than a bad switch. |
| Furnace inducer motor | $400–$1,100 | Furnace locks out before the burners light. |
| Furnace blower motor | $500–$2,300 | ECM variable-speed motors sit at the top of the range. |
| AC compressor | $1,800–$2,800 | The repair that most often tips toward replacing the unit. |

Capacitor replacement cost
The cheapest common failure on both furnaces and air conditioners, and the one to rule out first.
Price this part →Furnace blower motor cost
PSC and ECM motor pricing, and when the blower wheel or a capacitor is the real fault.
Price this part →Furnace inducer motor cost
What the draft inducer costs to replace when the furnace locks out before ignition.
Price this part →Furnace pressure switch cost
A cheap safety switch that often gets replaced when a blocked vent is the actual problem.
Price this part →AC compressor replacement cost
The most expensive single AC repair, and the point where replacing the unit starts to win.

A single part is one line on a bill. For the whole job, check furnace repair cost or AC repair cost, add the service call fee if it is not being credited, and if the system is old, run the $5,000 rule before you spend on a part at all. The full index is on the cost guides hub.
Not sure which part failed yet?
If nobody has diagnosed the system, start from the symptom. The HVAC troubleshooting hub walks the free, no-tool checks for a furnace that will not start, a furnace blowing cold, and an AC that runs without cooling. Plenty of calls end there, with no part replaced at all.

HVAC part cost FAQs
Which HVAC part fails most often?
Capacitors, igniters, flame sensors, and contactors are the parts technicians replace most, and they are also the cheapest. A capacitor runs $250 to $400 installed. That is worth knowing because several expensive-sounding symptoms, like a blower that hums but will not spin, are often a failed capacitor rather than a failed motor.
How do I know the quoted part is the part that actually failed?
Ask the technician what test confirmed it. A capacitor is checked with a meter against its rated microfarad value, a pressure switch is confirmed by checking the vent and drain for a blockage first, and a blower motor is tested before it is condemned. A written diagnosis that names the test is the difference between a repair and a guess.
Is it cheaper to replace one part or the whole system?
One part is almost always cheaper today. The question is whether it is cheaper over the next few years. Multiply the age of the system by the repair quote: above roughly $5,000 the replacement case gets strong, and a big-ticket part like a compressor on a system past twelve years usually loses that math.
Do these part prices include labor?
Yes. Every range on the linked pages is the installed price, part and labor together, based on published 2026 cost research. A separate diagnostic or service call fee of $75 to $200 may be charged before the repair begins, and some contractors credit it toward the work.
