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 here means Denver homes deal with spring snowmelt flooding as a regular fact of life. Building codes have evolved over the decades, and properties from the 1970s-2000s suburban growth often need updates to meet current standards. We know what to check and what to prioritize based on your home's age and construction type.

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 Denver 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 Denver?
- A standard furnace replacement typically takes 4-8 hours. If we're upgrading from 80% to 96% efficiency, we'll need to install new PVC venting which may add time.
- What efficiency furnace should I get?
- It depends on your climate and gas costs. In CO, a 96% AFUE furnace typically pays back its premium over 80% efficiency within 3-5 years through lower gas bills. We'll calculate the payback for your specific situation.
- What makes you different from other Denver companies?
- Transparent pricing, proper diagnostics, and honest recommendations. We'd rather walk away from a sale than recommend Furnace Replacement work you don't actually need.
- Do you offer emergency service?
- Yes — 24/7 emergency dispatch with an average response under 45 minutes in Denver. A real technician answers the phone, not an answering service.
- How do you handle unexpected issues during Furnace Replacement?
