HVAC Repair & Replacement Cost in Memphis, TN

Memphis costs for heat pump, AC, and furnace work

† Central AC replacement: High end reflects two-stage and variable-speed equipment, larger homes, and duct modifications; a standard-efficiency change-out on sound ductwork lands in the lower half.

† Furnace replacement: Electric furnaces sit at the low end; gas furnaces run $3,800 to $10,000 in most guides, and high-efficiency condensing units push past the high end.

† Heat pump installation (air-source): Sources disagree widely (>3x): contractor-network averages (Angi, Bob Vila, Today's Homeowner) cluster near $6,000 for a like-for-like change-out, while HomeGuide, This Old House, and Carrier quote $10,000 to $25,000 for higher-efficiency and cold-climate systems. Range widened to cover both.

† Ductwork replacement: Whole-home replacement in a 1,500 to 2,500 sq ft house; replacing a few runs costs a fraction, and retrofitting ducts into a home that never had them runs above the high end.

17th for cooling, 16th for heating: a two-way climate

Neither season wins in Memphis. At the Memphis International Airport station, 6 km from the city center, NOAA's 1991-2020 normals come to 2,314 cooling degree days and 2,875 heating degree days a year, and among the 33 metros on this index, Memphis sits mid-pack on both lists. A system that only does one job well leaves money on the table for the other half of the year.

That is the case for a heat pump. It cools in summer and runs in reverse to heat in winter, and Memphis winters are mild enough for it to do most of that heating efficiently: the January average low is 33°F, and only about 44 nights a year fall to freezing. Backup electric strips or a gas furnace cover the few cold snaps. An air-source installation runs $4,100–$14,700, typically about $7,800. Price it against what it replaces, which is usually a new AC ($5,900 typical) plus a new furnace ($4,700 typical) rather than either one alone.

The July service call: what breaks in a humid summer

About 72 days a year hit 90°F or more, the July average high is 92°F, and the station records about 3 days at 100°F. Long runs in that heat are when weak parts give out. The usual Memphis summer repairs are capacitors and contactors, condenser fan motors, refrigerant leaks, and condensate drains clogged with algae, since an air conditioner in humid air pulls gallons of water out of the house every day. Each of those usually costs somewhere in the $150–$650 range.

The expensive one is the compressor, typically $2,300. On a system past about 10 to 12 years old, that money is usually better spent toward a replacement, especially because a heat pump here works year-round and wears faster than an air conditioner that rests all winter.

Humid air, and why oversizing makes it worse

When a house feels clammy, the reflex is to buy more capacity. In a humid climate that backfires. An oversized system cools the air fast and shuts off before its coil has run long enough to wring out moisture, so the house ends up cold and damp. The fix is sizing done right: a Manual J load calculation that counts this house's insulation, windows, and duct losses, then equipment chosen to match. Two-stage and variable-speed units, which run longer at low speed, handle moisture better still, and they account for much of the upper end of the $3,900–$11,800 replacement row.

Wind and lightning, more than hail, for the outdoor unit

Shelby County's hail record is modest: 22 days of inch-plus stones over 2016–2025, placing it 23rd of 33. Damaging thunderstorm wind was more frequent: 74 days, ranked 14th, with a peak of 90 mph. For an outdoor unit, that means limbs and debris more often than hailstones.

A tree falling on a condenser, a lightning surge that fries a control board, a fire, or hail heavy enough to crush a coil are the cases homeowners insurance usually covers, after your deductible. The usual way a Memphis system fails, a compressor or blower motor wearing out after years of long summers, is excluded as wear or breakdown. Manufacturer warranties tend to pay for parts on younger equipment but not the technician's time. A home warranty plan, a service contract rather than insurance, exists for that gap.

Southeast rules for a new system in Memphis

Tennessee falls in the Department of Energy's Southeast region, where a new central air conditioner must reach at least 14.3 SEER2. Ask any installer to put the model's rated SEER2 in writing. New split systems are also built for R-454B or R-32 rather than the older R-410A. An existing R-410A system can still be repaired and recharged, but a new outdoor unit generally needs a matching indoor coil, so a "just the condenser" quote deserves a question.

Labor here prices at a 0.98 factor, set from Tennessee's statewide construction wage because the Memphis metro figure is withheld. For comparison, Nashville has its own published metro wage and a 1.02 factor.
