Maintenance Plan

The Comfort Club. Two visits a year. One predictable bill.

Most furnace and AC breakdowns are preventable. Dirty blower wheels, clogged condensate lines, weak capacitors, low refrigerant — we catch all of them on a tune-up before they leave you sweating in August or freezing in February.

Comfort Club members get two scheduled visits a year (spring AC tune-up, fall furnace tune-up), 15% off any repair, priority dispatch when the heat wave hits, waived overtime fees on after-hours calls, and a multi-year price lock if you sign a three-year agreement.

Why Northway

Why Indianapolis families call us back.

Real techs, not 1099 referrals.

Every Northway tech is a W-2 employee, NATE-certified, background-checked, and wears the same uniform you saw last time. We don't subcontract emergency calls to whoever's available. The person on your driveway tonight is the same person who'll handle your tune-up next April.

Up-front pricing in writing.

$89 diagnostic fee, credited to any repair you approve. Repair quotes given before we start, in writing, on a tablet — you sign or you don't. No "while we're in there" surprises, no $400 add-ons after the panel goes back on. The number we quote is the number on the invoice.

30-day labor warranty.

Every repair carries a 30-day labor warranty in addition to the manufacturer's parts warranty. If the same problem comes back inside 30 days, we come back free — no diagnostic fee, no callout fee, no argument. That's how confident we are in the work.

"Called at 10pm on a Wednesday with no AC and a 3-year-old in the house. Dispatcher answered on the second ring. Tech showed up before midnight, had a new capacitor on the truck, cool air by 12:30. $89 diag plus $215 part — same price he'd quoted me on the phone."

"Got three quotes on a furnace replacement. Northway wasn't the cheapest but Dan himself came out, walked the basement with me, explained why a 95% AFUE two-stage made more sense for our 1920s Carmel home than the bigger unit the other shop pushed. Install crew was on time, clean, done in a day."

"Comfort Club for three years now. Eddie has done four of my tune-ups. He always vacuums up after himself and tells me straight when I have a few years left on the system. No one's tried to upsell me. Just honest work."
