Trane AC, furnace and heat pump prices

Trane is one of the few manufacturers that publishes installed price ranges. These come from its own 2026 replacement cost guide.

Trane says its ranges include the unit and labor, plus the basic accessories and services a dealer provides, before tax. They do not include accessories such as a thermostat, and the guide notes that estimates do not include required accessories or installation requirements. This Old House says to treat a brand average as a starting point, not a guaranteed price.

You cannot buy a Trane system from the manufacturer at a list price. Trane sells through independent local dealers, and each dealer sets its own installed price. Trane's guide says a local dealer can give exact pricing after evaluating your home.

Three things explain most of the spread in the table:

• Tier. Each product line comes in a single-stage, a multi-speed or two-stage, and a variable-speed version. Moving up a tier raises the price more than moving up a size.
• Size. A larger house needs more tons of cooling or more BTU of heat.
• Installation. Labor, refrigerant lines, electrical work, duct changes, permits and removal of the old system make up a large part of every quote. Two homes with the same unit can get very different prices.

The AC replacement cost guide breaks down size, SEER2 and regional factors for any brand.

Trane describes two levels of manufacturer coverage. The Base Limited Warranty applies to units that are not registered. The Registered Limited Warranty lengthens the term if the product is registered within 60 days of installation. Both cover parts that fail due to a manufacturer defect. Trane states that the cost of labor is not covered under either one.

Ask the dealer whether they register the equipment for you, and get the confirmation. Ask what labor warranty the dealer adds, since that comes from the installer.

• Exact model numbers for the outdoor unit, the indoor coil or air handler, and the furnace. A brand name alone tells you very little.
• Size and efficiency. Tons or BTU, SEER2 for cooling, and whether the compressor is single-stage, two-stage or variable-speed.
• How the size was chosen. A load calculation for your house beats copying the old unit's size.
• Scope of installation. Refrigerant lines, pad, electrical, drain, duct changes, thermostat, permit and removal of the old equipment.
• Warranties. The manufacturer's parts term, who registers the equipment, and the installer's own labor warranty in writing.

If you are comparing a Trane quote with another brand, line up the tier, size and scope first. A variable-speed system from one dealer and a single-stage system from another are different products. More replacement prices are in the HVAC cost guides.
