Furnace replacement

A furnace sized for your house — not for whatever the last guy happened to have on the truck. We haul the old one out, pull the permit, and meet the inspector.

When August wins

AC replacement

Condensers and coils matched to the ductwork you actually have, on the current refrigerant, charged and tested before we pull out of the driveway.

The honest answer

Fix or replace it?

Slide these around. It's the same math our techs run standing in your basement, and it doesn't ask for your email first.

This is a rule of thumb, not a diagnosis. The real answer depends on the heat exchanger, what refrigerant it takes, how your ducts are breathing, and what the rest of the system is up to.

Fix it, but start looking

This repair is defensible. But a system this age is on borrowed time, and shopping in July beats shopping at 11pm in January.

The $5,000 rule — age × repair cost. Past $5,000, the repair stops paying for itself.
14 × $1,400 = $19,600

Paying for it

Need financing?

Furnaces don't wait for a good month. Financing is available for approved applicants, so a replacement doesn't have to come out of savings all at once.

  • Financing available. Approved applicants can spread the cost of a replacement over time.
  • Apply before we leave. We can start the application right at your kitchen table.
  • We do the rebate forms. Every one that applies to the equipment you bought.

Here's exactly how this goes

01

We come look

Measure the house, check the ducts and the electrical, take pictures. Nobody quotes a system over the phone and neither do we.

About an hour · no charge
02

You get a real number

Three options, itemized, with the monthly payment printed next to each. Permit, haul-away, and startup are already in there.

Same or next day · good 30 days
03

We swap it out

Floors covered, old unit out, new one set and wired and charged and started. We walk you through it before we leave.

Most jobs, one day
04

We don't disappear

Permit pulled, inspector met, warranty registered, rebates filed. Then we come back once for a free tune-up after the first season.

Why us

Small company.
Big attention to detail.

We're a small, locally owned company, and we sweat the little things most outfits skip. That starts with a real load calculation on your house instead of a guess off the old unit's sticker, so the system actually fits.

  • Manual J on every quote. Room by room, so the system fits the house you actually live in.
  • We test static pressure. No point selling you equipment that has to breathe through a straw.
  • Same crew, start to finish. The tech who quoted it is on site the day it happens.
  • Fixed written price. Change orders only if you sign off first. The invoice won't surprise you.
