Full System Replacement Costs
When repair isn't worth it — what a new system actually costs installed. Find HVAC installers near you →
Installed cost includes equipment, labor, and standard setup. Complex retrofits or duct modifications add $500–$2,000+.
| System Type | Low Cost | High Cost | Notes |
|---|---|---|---|
| Central AC Only (3 ton) | $3,200 | $7,000 | Labor + equipment + basic installation. |
| Gas Furnace Only (80K BTU) | $2,500 | $6,500 | High-efficiency models cost more upfront, save over time. |
| AC + Furnace Bundle (Split) | $5,800 | $12,000 | Best value when both units are old. |
| Heat Pump System (ducted, 2–3 ton, standard efficiency) | $7,600 | $9,500 | Heating and cooling in one system. Range from the NREL/LBNL installed-cost model (2022 dollars). Cold-climate and high-efficiency systems cost more. |
| Mini-Split (Ductless, 1 zone) | $1,800 | $5,000 | No ductwork needed. Great for additions/garages. |
⚠️ Pricing Disclaimer: Prices shown are editorial estimates of typical U.S. ranges, not
quotes. Actual service costs vary based on location, system type, and repair complexity.
How these compare with published research: the NREL/LBNL study “Heat pumps for all?” (Joule, 2024) models installed costs in 2022 dollars. Its cost equation puts a standard-efficiency ducted heat pump (SEER 15, HSPF 9) at about $7,600 for 2 tons and $9,500 for 3 tons, the basis of the heat-pump row above, and it uses a median of about $6,345 for a 3-ton central air conditioner. Its high-efficiency cold-climate heat pump scenario averaged about $22,400 for ducted equipment.
Service life: DOE’s federal purchasing guidance assumes an average life of 18 to 25 years for a central air conditioner depending on region, 15 years for an air-source heat pump, and 21 years for a furnace. These are modelling assumptions, not guarantees; see the FAQ below.
Service Call, Tune-Up & Emergency Fees
What a diagnostic visit, a seasonal tune-up, and after-hours service typically cost. Facing an HVAC emergency now? →
After-hours and holiday surcharges are added to the base repair cost — they do not replace it.
| Service Type | Typical Cost | Notes |
|---|---|---|
| After-Hours Emergency Call (nights/weekends) | $100–$300 extra | Added on top of repair cost. Varies by company and region. |
| Diagnostic / Service Call Fee | $65–$150 | Some providers credit it toward the repair if you book it with them. Ask when you call. |
| Holiday Emergency Premium | $100–$300 extra | Some providers charge a holiday rate. Confirm the fee when you call. |
| Annual Maintenance Contract | $150–$350/yr | Plan terms vary. Ask how many tune-ups are included, what priority scheduling means, and whether repairs are discounted. |
| Seasonal Tune-Up (one visit) | $80–$200 | Preventive check of a working system. See the FAQ below. |
Repair vs. Replace: The $5,000 Rule
A rule of thumb, not an industry standard
Multiply the age of your system by the cost of the repair.
- If the result is below $5,000 → repair is likely worth it
- If the result is over $5,000 → replacement is often better value
Example: System is 12 years old. Repair quote is $600.
12
× 600 = $7,200. Over $5,000 → replacement may be better value long-term.

What Affects HVAC Repair Cost the Most?
Not all HVAC quotes are equal. Several factors can push a repair bill from the low end to the high end of any range on this page:
- System age and brand: Older or discontinued equipment can have harder-to-source parts, which can push the same repair toward the high end of its range.
- Refrigerant type: R-22 refrigerant, found in systems manufactured before 2010, costs far more than R-410A: $90–$150 per pound versus $20–$50 in this guide’s estimates. EPA ended U.S. production and import of R-22 in 2020, so an R-22 system that needs refrigerant is a strong candidate for a replacement quote. See our refrigerant cost breakdown →
- Emergency timing: After-hours and weekend calls add $100–$300 to any repair. See emergency fee details above.
- Labor market and region: Labor rates differ from one market to the next, so the same repair can be priced differently depending on where you live. See the regional differences section below.
- Extent of diagnosis: Technicians who perform thorough diagnostics may find secondary issues. This is normal — not a scam — and may actually save money long-term.
- Warranty status: If your equipment is under manufacturer warranty, parts may be covered; labor may not be. Check the warranty terms before authorizing work.
If you're unsure whether a quote is fair, get a second opinion. Read our HVAC safety tips to avoid rushed decisions in an emergency.
How to Read an HVAC Quote Line by Line
A fair quote is itemized. If a technician gives you one lump-sum number, ask for the lines before you approve anything. These are the lines to expect, checked against the ranges on this page.
1
Diagnostic or service-call fee
$65–$150; some providers credit it toward the repair if you approve it. Nights, weekends, and holidays add $100–$300 (see emergency fees).
2
Parts and labor, listed separately
Each part should be named and priced, with labor shown on its own line. Compare the total against the AC and furnace repair ranges above. If a line can’t be explained, ask again before you sign.
3
Refrigerant, only with a leak plan
An R-410A recharge runs $150–$600. A quote that adds refrigerant should also say how the leak was found and whether it will be repaired. Refrigerant work requires an EPA Section 608-certified technician.
4
Replacement add-ons, in writing
Ask about the permit and inspection, haul-away of old equipment, recovery of the old refrigerant (EPA rules prohibit venting it), duct or line-set changes, pad or bracket, electrical work, thermostat, and who registers the warranty. Then ask for one out-the-door price.
Quote Red Flags: When to Get a Second Opinion
These four patterns are worth pausing on before you pay.
“Leaking coil” with no test shown
Coil replacement runs $600–$2,000 for an evaporator coil and $900–$2,800 for a condenser coil. Ask how the leak was located and to see the result before you approve it.
A refrigerant top-off with no repair
If a system needs refrigerant, the charge went somewhere. Adding refrigerant without fixing the leak means paying for the same visit again.
“Your compressor is shot” with no readings
A compressor diagnosis should come with the electrical and pressure readings the technician took. Ask to see them before a $1,200–$3,500 decision.
A service call priced far below $65
Very low advertised call fees can come with trip fees or minimum charges once the technician arrives. Confirm the full fee on the phone before booking.
If a quote shows any of these, a second quote is cheap insurance. Call (844) 582-1795 to reach an independent technician, or work through our repair-or-replace framework first.
Regional Price Differences
Where you live affects what you pay, because labor rates, demand, and local permit rules differ from market to market. This guide does not apply regional percentage adjustments, because we have no dataset that measures them. What you can do instead:
- Get local quotes: 2–3 written, itemized quotes from providers in your area are the most direct way to see what your market charges.
- Ask about trip or travel fees: some providers add a charge for longer drives, which can matter in rural areas. Confirm it on the phone before booking.
- Plan around busy seasons: ENERGY STAR notes that contractors get busy once summer and winter come. Scheduling a check-up or a planned replacement in spring or fall leaves time to compare quotes.

HVAC Cost — Frequently Asked Questions
Tap a question to expand.
A diagnostic or service-call fee, $65–$150 in this guide, covers the provider's time to identify the problem. Some providers credit it toward the repair if you book it with them; others charge it regardless. Ask upfront.
In this guide, after-hours surcharges add $100–$300 to the repair cost for nights and weekends, and holiday calls can add $100–$300. These are in addition to — not instead of — the standard repair cost. Confirm the fee when you call.
It depends on the type. This guide estimates R-410A at $20–$50 per pound. EPA ended U.S. production and import of R-22 in 2020, so older R-22 systems rely on existing supplies, estimated here at $90–$150 per pound. On an R-22 system, a large recharge can cost enough that a replacement quote is worth comparing.
One rule of thumb, not an industry standard, is the $5,000 Rule: multiply the system's age by the repair cost, and if the result is over $5,000, get a replacement quote to compare. ENERGY STAR also suggests having a contractor evaluate a heat pump or air conditioner that is more than 10 years old, or a furnace or boiler more than 15 years old. R-22 refrigerant and repeated repairs are other reasons to compare.
In this guide, yes: compressor replacement ($1,200–$3,500) is the most expensive single AC repair. If the compressor fails on a system more than 10 years old, compare the repair quote with a replacement quote; ENERGY STAR suggests a contractor evaluation for air conditioners past that age. Always get a written quote before authorizing compressor work.
Generally not when a system simply wears out or breaks down. NAIC's consumer guide to home insurance notes that a homeowners policy is not a maintenance contract and does not pay to repair items that simply wear out. Its dwelling coverage does include damage to heating and permanently installed air-conditioning systems from covered perils such as fire, wind, or hail. A home warranty is a separate contract that covers mechanical breakdown, with its own exclusions and limitations. Check your own policy before assuming coverage.
It should, but always confirm. Ask for an itemized quote that separates parts cost, labor cost, and any fees (diagnostic, disposal). If a quote is vague, ask for clarification before authorizing work.
Yes, within reason. You can ask if the diagnostic fee will be waived, request a bundle discount if multiple repairs are needed, or ask about financing options. Getting 2–3 written quotes for major repairs lets you compare prices before you commit.
Annual maintenance contracts cost $150–$350 a year in this guide's estimates. Plans vary, so ask how many tune-ups are included, what priority scheduling means, and whether repairs are discounted. Compare the plan price with paying for tune-ups one visit at a time ($80–$200 per visit in this guide).
Yes. Labor rates, demand, and local permit rules differ between markets, so the same job can be priced differently in different places. This guide shows typical U.S. ranges and does not apply regional percentage adjustments; 2–3 local, written quotes are the most direct way to see what your market charges. See the regional price section above.
A tune-up ($80–$200 in this guide) is preventive maintenance on a working system; a repair fixes something that has already broken. ENERGY STAR recommends annual pre-season check-ups by a contractor: the cooling system in spring and the heating system in fall.
DOE’s federal purchasing guidance assumes an average life of 18 to 25 years for a central air conditioner depending on region (18 years in Hot-Humid/Southeast states, 25 in Hot-Dry/Southwest states, 24 in Northern states), 15 years for an air-source heat pump, and 21 years for a furnace. These are modelling assumptions, not guarantees. ENERGY STAR suggests having a contractor evaluate a heat pump or air conditioner once it is more than 10 years old, and a furnace or boiler once it is more than 15. If an older system needs a major repair, compare the repair quote with a replacement quote.
There is no guaranteed cheapest month, but timing affects your options. ENERGY STAR notes that contractors get busy once summer and winter come, which is why it recommends spring check-ups for cooling and fall check-ups for heating. If your system still works, planning a replacement in spring or fall leaves time to collect 2–3 quotes instead of taking the first available install during a breakdown.
