HVAC Contractors

Replacing a heating or cooling system is one of the largest unplanned bills a household meets, and 2 quotes for the same house can differ by thousands for reasons rarely explained on the page. Efficiency rating, compressor type, and whether your existing ductwork can be reused move the number further than the brand on the box does. The table above carries current manufacturer ranges for 4 equipment types.

Air conditioner replacement

What moves the price

  • SEER2 rating. A higher efficiency unit costs more up front
  • Single stage, two stage or variable speed compressor
  • Whether existing ductwork can be reused or has to be replaced
  • System size, which follows house size and climate rather than preference
  • How hard the equipment is to reach and how much of the old system comes out

Usually included

  • Equipment, installation labor, system testing and commissioning

Quoted separately

  • Ductwork replacement
  • Electrical panel upgrades
  • Thermostat and accessories
  • Permit fees where the city requires one

Furnace replacement

What moves the price

  • AFUE rating. Higher efficiency costs more up front and less to run
  • Single stage against two stage or modulating burner
  • Gas, electric or oil, and whether the fuel type is changing
  • Venting work, which is where a straightforward swap stops being straightforward
  • Whether the furnace shares ductwork with an air conditioner being replaced at the same time

Usually included

  • Equipment, installation labor, venting connection and testing

Quoted separately

  • Ductwork
  • Gas line alterations
  • Permit fees where the city requires one

Heat pump replacement

What moves the price

  • Standard against cold climate model. Cold climate units run higher, roughly $7,983 to $17,012 on the same source
  • Whether it replaces both heating and cooling or works alongside an existing furnace
  • Ductwork condition, or whether the install is ductless
  • Electrical capacity, since a heat pump can need panel work a furnace does not
  • System size, set by house size and climate

Usually included

  • Equipment, installation labor, system testing and commissioning

Quoted separately

  • Electrical panel upgrades
  • Ductwork
  • Backup heat where the climate needs it
  • Permit fees where the city requires one

Air handler replacement

What moves the price

  • Matched to the outdoor unit, so it is often replaced with it rather than alone
  • Variable speed against single speed blower
  • Whether existing ductwork can be reused
  • Access to the installation location

Usually included

  • Equipment and installation labor

Quoted separately

  • Ductwork replacement
  • Electrical panel upgrades
  • Thermostat and accessories
  • Permit fees where the city requires one
How do we know these prices?

Every figure above comes from a named source we can link to, with the date we last checked it. We publish ranges rather than single prices because a range is what a provider will actually give you: the same job moves with what is being worked on, the materials, how hard it is to get at and how busy the trade is locally. Treat these as the order of magnitude to expect before you call, not as a quote.

The figures here are national. Where a source publishes figures state by state, the state pages carry that local figure instead of this one. We do not scale a national number by a multiplier of our own invention.

Every range carries a review date. When that date passes the number comes down until it is rechecked, rather than sitting here undated.

What replacement costs

Manufacturer figures, checked September 2026. Treat them as the shape of the bill rather than a quote.

Those spreads are wide because they cover a basic single stage unit dropped into good existing ductwork at one end, and a variable speed high efficiency system with duct and electrical work at the other.

What moves the number

Efficiency rating. SEER2 on cooling, AFUE on heating. A higher rating costs more up front and less every month after. Whether that trade pays back depends on how long you keep the house and how hard the system works where you live.

Ductwork. The quiet budget killer. If the existing runs are sound, the new equipment connects to them. If they leak, are the wrong size for the new system, or were never balanced properly, the quote climbs and the good contractors will tell you so before they start.

Sizing. An oversized system short cycles, and short cycling means it never runs long enough to pull humidity out of the air. You get a house that is cold and clammy, and a compressor that wears out early.

Access. An attic air handler in July costs more to swap than a garage unit at chest height. Same equipment, different day.

How to tell a real quote from a guess

A contractor who quotes a system size from the square footage of your house, or from whatever was there before, is guessing. Whatever was there before may well have been wrong.

A proper load calculation measures the house: window area and orientation, insulation, ceiling heights, air leakage, which rooms face the afternoon sun. It takes an hour or two and it produces a number in tons or BTUs that the contractor can show you. Ask to see it. A quote that arrives without anyone having measured anything is a quote for equipment, not for a working system.

The other thing worth watching is how the visit goes. Someone who looks at your ductwork, your electrical panel and your existing venting is pricing the job. Someone who looks only at the outdoor unit is pricing a box.

What to ask before you sign

  • Did you run a load calculation, and can I see it?
  • What size is the new system, and how does that compare to the old one?
  • What condition is my ductwork in, and is any duct work included in this price?
  • What is the SEER2 or AFUE rating, and what would the next rating up cost?
  • Does this job need a permit, and is the permit fee in the quote?
  • What is the warranty on the equipment, and separately on your labor?
  • Who comes out if it fails in February, and what does that call cost?

Repair or replace

There is no clean rule, but there are two useful signals. Age against expected life: most systems are considered near the end somewhere past the fifteen year mark, and a large repair on a system that old is money spent on a machine you will replace anyway. And repeat failures: one part is a repair, three parts in two years is a system telling you something.

If a contractor pushes straight to replacement on a system under ten years old without diagnosing the fault, get a second opinion. If a contractor keeps repairing a twenty year old unit without ever mentioning replacement, get one too.

How to choose an HVAC contractor

HVAC is a licensed trade in most states, but the body that licenses them, the classifications, and what falls outside a license all change at the state line. Some states license the contractor, some license the individual technician, some do both. The state pages carry the detail for each one.

Common questions

How much does it cost to replace an air conditioner?

Nationally $6,568 to $13,669, covering equipment, installation labor and commissioning. Where a job lands in that span comes down mostly to the SEER2 efficiency rating, whether the compressor is single stage, two stage or variable speed, and whether the existing ductwork can be reused. Ductwork replacement, electrical panel upgrades, thermostats and permit fees are quoted separately.

Is a heat pump more expensive than a furnace?

On the same source, yes: heat pump replacement runs $7,369 to $15,608 against $5,093 to $8,390 for a furnace. A cold climate heat pump runs higher again, roughly $7,983 to $17,012. A heat pump can also need electrical panel work that a furnace does not, which is quoted on top.

What is quoted separately on an HVAC replacement?

Ductwork, gas line alterations on a furnace, electrical panel upgrades on a heat pump, thermostats and accessories, and permit fees where the city requires one. Ask which of these are in the number you have been given before you compare two quotes.

Why does the same system cost different amounts at two companies?

Equipment is only part of the price. The efficiency rating, whether the burner or compressor is staged, how hard the equipment is to reach, how much of the old system comes out, and how much venting or duct work the install needs all move it.
