How we decide

Four questions. In this order.

This is how we think it through on every visit, out loud, with you. Then you decide. No pressure, no deadline.

  1. 01

    Is it safe?

    A cracked heat exchanger or a leaking coil is a replace. No debate. We show you the evidence first.

  2. 02

    Age × repair cost

    Under $5,000, repair usually wins. Over it, we price both. A younger system with a modest repair is an easy call.

  3. 03

    What would efficiency save?

    An old 80% furnace next to one that’s up to 99% efficient is real money every winter. We put your Xcel bill on the estimate.

  4. 04

    What can you afford this year?

    Sometimes the right answer is repair now, plan the replacement, and stop paying for emergencies.

Second opinions

What people ask.

What is the “$5,000 rule”?

Multiply the system’s age by the repair quote. Under $5,000, repair. Over, start pricing replacement. It’s a rule of thumb the whole industry uses; the calculator above applies it and adds efficiency and safety.

Does a cracked heat exchanger always mean replacement?

For a furnace over 15 years old, yes. The part alone costs most of a new furnace, and it’s a carbon monoxide safety issue. We show you the crack with a camera before we say so.

Will you push replacement?

No. Our technician isn’t paid on commission. Several Google reviews are from homeowners another company told to replace, and we fixed the unit instead.

What if I can’t afford to replace right now?

We say so and repair it. Then we help you plan: a maintenance plan to stretch it, financing with approval in minutes, and Xcel rebates on the eventual replacement.
