Nobody should have to sit through a sales visit just to learn the ballpark. So here it is, the same way we publish all our cost guides: the honest ranges we see in the Mid-South market, and what moves a house up or down inside them.
The range: most straightforward full-system replacements in our area — matched outdoor unit and indoor equipment, typical 2.5-to-4-ton home — land roughly between $6,000 and $12,000 installed. Basic single-stage AC-and-furnace setups run the low half; heat pumps, dual-fuel pairings, and higher-efficiency variable-speed equipment run the upper half. Your house sets your exact number, which is why replacement quotes are free — but that's the honest neighborhood.
What actually moves the number: capacity, decided by a load calculation of your actual house (never by matching the old unit's sticker — oversizing is the most expensive mistake in this business, and it's the one that leaves a Tennessee house cold-but-clammy). Efficiency tier — today's baseline equipment is already decent; stepping up buys quieter operation, better humidity control, and lower bills, and we'll show you the payback math rather than assume. Equipment type — straight AC, heat pump, or dual fuel, which is a climate-and-gas-availability decision we covered in its own guide. And ductwork: if yours leaks or was sized wrong, fixing it adds real dollars AND is frequently the difference between a new system that disappoints and one that finally makes the house comfortable. A quote that ignores bad ductwork isn't a cheaper quote — it's an incomplete one.
The repair-or-replace math we actually use: multiply the repair estimate by the system's age. North of about $6,000 — say, a $700 repair on a 10-year-old system — and you're funding a machine on its way out. Under that, repair with confidence. Big-ticket failures (compressor, heat exchanger) past year 12 almost always tip to replacement; cheap parts (capacitors, contactors) almost never do, at any age.
Red flags wherever you shop: a price quoted over the phone sight-unseen, no load calculation, and pressure to sign today. A real number requires looking at your house; anyone who skips the looking is guessing with your money.
Our promise stays the same on the biggest ticket we sell: the full installed price upfront, honest input on whether this is the year, and no surprise line items ever: (901) 699-7763.
