HVAC repair and install in Carmel, Indiana.

HVAC service in Carmel since 1986.

Northway has serviced Carmel residential HVAC since 1986 — back when the city was a fraction of its current 100,000 population and Main Street still ended in farmland. We currently maintain 800+ active systems across Carmel neighborhoods including Brookshire, Foster Estates, The Village of WestClay, Spring Mill Estates, Cool Creek, and Mohawk Hills. Most Carmel calls dispatch in under an hour because we're eight minutes off Main & Range Line via Keystone Parkway.

If you've lived in Carmel long enough, you've probably seen one of our trucks on your block. We send the same crew back to the same houses for tune-ups, and the senior techs know the older Carmel homes' quirks — the early-90s WestClay basements that didn't get high-efficiency furnaces, the 2010s Spring Mill homes with the variable-speed Carriers that need a particular blower-control update, the older Mohawk Hills attic units that show up every August.

What we do in Carmel.

Same-day AC repair in Carmel.

$89 diagnostic, credited toward any repair you approve. Written quote on a tablet before any work starts. Most Carmel AC calls run a NATE-certified tech to your driveway in 45–75 minutes. See the full AC repair page for pricing ranges and warranty terms.

Most Carmel installs done in one day. Financing through Synchrony and Wells Fargo. See furnace install for installed pricing.

Comfort Club maintenance plans for Carmel homes.

$18.95/mo per system or $199/yr — two tune-ups a year, 15% off repairs, priority dispatch in heat waves, waived after-hours fees. Carmel has the heaviest Comfort Club concentration in the metro because the 1990s and 2000s build-outs are now hitting the maintenance sweet-spot. See Comfort Club details.

24/7 emergency dispatch — we're 8 minutes from Main & Range Line.

Heat out at 11pm in February. AC out in August at 1am. Northway's emergency dispatcher answers on the second ring and our on-call tech is rolling fast — Carmel emergencies typically arrive under an hour from anywhere on the east side of US-31. After-hours diagnostic $149, waived for Comfort Club members. See the emergency page.

Local rebate programs Carmel customers should know about.

Carmel is in Citizens Energy and IPL territory, both of which run rebate programs for high-efficiency residential HVAC. Citizens Energy currently offers $300–$600 rebates on 95%+ AFUE furnaces and 16+ SEER air conditioners; IPL offers similar incentives on heat pumps and ECM blower motors. Northway files the rebate paperwork with you at install time so you don't have to chase it.

At the federal level, the Energy Efficient Home Improvement Credit (Section 25C) can return up to $600 on qualifying high-efficiency furnaces and up to $2,000 on heat pumps installed in 2024 or later. Combine federal credits with state-utility rebates and you can often shave $1,200–$2,500 off the install cost of a comfort-tier two-stage system in Carmel.
