Our Furnace Replacement Process
Here's how we handle Furnace Replacement — from the first phone call to the final walkthrough. Replacing a furnace means matching the right AFUE rating, venting type, and BTU output to your home. We start by measuring your existing ductwork, checking gas line sizing, and evaluating your chimney or direct-vent setup. If you're upgrading from 80% to 96% efficiency, we'll need to run new PVC vent piping — something we handle in-house. Every Furnace Replacement includes removal of the old unit, new gas connections with leak testing, thermostat wiring, and a combustion analysis to confirm safe CO levels. We pull the permit, schedule the inspection, and don't leave until your heat is running right.

The semi-arid continental climate creates dry winter air, which accelerates wear on specific systems.

Furnace Replacement — Frequently Asked Questions
- Do you remove the old furnace?
- Yes. We disconnect, remove, and properly dispose of your old furnace, including refrigerant recovery from connected AC systems per EPA regulations.
- What permits are required?
- Furnace replacements in Castle Rock require a mechanical permit and city inspection. We pull the permit, schedule the inspection, and ensure everything meets code.
- How long does furnace installation take in Castle Rock?
