A furnace or air conditioner rarely fails on a convenient week. We work with a third-party lender that offers monthly payments on larger installs, subject to credit approval. Your comfort advisor will show you the current rates next to the cash price.
Illustrative example only. Rates, terms and approval are set by the lender and may differ for your project.

Furnace quit at 11pm on the coldest night of January. The technician was in our basement before midnight, replaced the igniter and showed me the cracked one. The price matched what we were told on the phone.
They talked us out of a bigger AC. The load calculation said two and a half tons, not the four another company quoted. The house is cooler and our July bill went down.
Our upstairs bedrooms ran six degrees warmer than the rest of the house. They sealed and balanced the ducts in one day. First summer without a window unit.
We swapped an oil boiler for a cold-climate heat pump. Northline filled in the rebate paperwork and kept the bathroom radiators on a small electric loop. February was fine.

A repair diagnostic is a flat fee, and it is credited in full toward any repair you approve. Estimates for a new system are free and include a room-by-room load calculation and written options.
Once a year for a furnace or boiler, once a year for central air, and twice a year for a heat pump because it runs in both seasons. Spring and early fall are the easiest times to book.
It depends on the house, not just its square footage. A free in-home visit gives you a proper load calculation before you buy anything, so you never pay for more capacity than you need.
Yes. We service all common makes of furnaces, boilers, air conditioners and heat pumps, and we are not tied to a single manufacturer, so the system we recommend is the one that fits your home.
Please do. Check it monthly and replace it every one to three months. On your first visit we will mark the filter size on the cabinet and show you which way the arrow points.
Tune-up slots fill three weeks out once the weather turns. Members are booked first, and anyone can book a one-off visit.
