If you're a homeowner in Indiana and your AC unit just gave up the ghost, or your furnace is making noises that keep you up at night, you're probably wondering: how much is this going to cost me? I get it. HVAC work isn't cheap, and you want to know what you're walking into before you call a contractor.
I've been helping homeowners across Indiana find HVAC solutions for years, and the pricing question comes up constantly. The truth is, costs vary depending on where you live in the state, what equipment you need, and whether you're dealing with a repair or a full replacement. Let me break down what you should expect to pay in 2025.
Indiana's HVAC costs don't vary wildly from city to city, but there are some differences worth knowing about. Indianapolis, being the largest metro area, tends to have competitive pricing because there are more contractors competing for business. You're looking at anywhere from $5,500 to $9,500 for a full AC and furnace replacement in the Indianapolis area.
Head up to Fort Wayne, and prices are pretty similar—usually $5,200 to $9,000 for a complete system replacement. Evansville and South Bend typically run in the same ballpark, between $5,000 and $9,200. The variation in these numbers depends mainly on the size of your home, the efficiency rating of the equipment, and whether you need ductwork modifications.
One thing I've noticed is that rural areas outside these cities sometimes pay a bit more because contractors have to travel further. But we're talking maybe $300 to $500 more, not a huge jump.
Not everyone needs a full system replacement. If you're just dealing with a repair, here's what you can realistically expect:
AC Repair: A straightforward air conditioning repair runs $250 to $600. This might be a refrigerant leak fix, compressor issue, or electrical problem. If it's something simple like a blower motor replacement, you might be on the lower end. A compressor replacement? That's going to push you toward $800 to $1,200.
Furnace Repair: Furnace repairs typically cost between $200 and $500. A simple thermostat replacement or flame sensor fix won't break the bank. But if you need a heat exchanger replaced, you're looking at $800 to $1,500, and sometimes those repairs aren't worth it if the furnace is already ten years old.
New AC Unit Only: If you just need to replace your air conditioner and keep your existing furnace, expect $3,500 to $5,500 depending on the unit's SEER rating. A basic 14 SEER unit will be cheaper than a high-efficiency 18+ SEER model.
New Furnace Only: A furnace replacement by itself runs $2,500 to $4,500. Again, efficiency matters here. A 95% AFUE furnace costs more upfront than an 80% AFUE, but you'll save on energy bills.
Full System Replacement: This is what most people end up doing eventually. A new furnace and AC system together typically costs $5,500 to $9,500 in Indiana, installed and ready to go.
Your actual quote isn't just a random number. Several factors influence what you'll pay:
Home Size: A 1,200 square foot ranch costs significantly less to heat and cool than a 3,500 square foot two-story. Larger homes need more powerful equipment.
Equipment Efficiency: Higher efficiency ratings (SEER for AC, AFUE for furnaces) cost more upfront. But in Indiana's climate—where you're running heat in winter and AC in summer—a more efficient system pays for itself in 5 to 7 years.
Ductwork: If your existing ducts are in bad shape or your home doesn't have ducts at all, you're adding $1,500 to $3,000 to the project. This is common when people convert from baseboard heating or add AC to an old furnace-only setup.
Existing Installation: Is your HVAC in an accessible attic, or is it in a tight basement crawlspace? Easy access means lower labor costs. Same goes for whether you need new electrical work or structural modifications.
Season: Yeah, it matters. In January or July when everyone's calling for emergency repairs, you might pay premium pricing. Spring and fall are typically cheaper times to schedule new installations.
Here's the real talk: you don't always have to go with the cheapest quote. But you can be smart about timing and maintenance. Schedule your replacement in the off-season if you can. Keep up with annual maintenance—$120 to $180 per year for a tune-up prevents expensive emergency repairs down the line.
Some contractors offer financing options, and don't sleep on manufacturer rebates. Sometimes you can get an extra $200 to $500 back on efficient equipment purchases. Ask your contractor about this.
Q: Is it cheaper to repair my old HVAC or replace it?
A: If your system is over 12 years old and the repair cost is more than 50% of a replacement, replacement usually makes sense. Older systems lose efficiency and will keep breaking down.
Q: Do I need to replace both the furnace and AC at the same time?
A: Not necessarily, but if they're the same age and both failing, doing them together saves on labor costs. You're paying for one service call instead of two.
Q: What's the most common HVAC problem in Indiana?
A: Refrigerant leaks in the summer and heating system failures in the winter. Our temperature swings put real stress on equipment. Maintenance helps prevent both.
