Easy Furnace Installation Process

Step 1: Free Consultation & Quote

Our process starts with a visit from a certified technician who will evaluate your current system and home layout. We take into account your square footage, insulation, ductwork condition, and heating preferences to recommend a furnace that fits your exact needs. You’ll receive a written quote with full pricing breakdown, furnace model options, and available rebates or financing.

Step 2: Removing Your Old Furnace

We begin installation day by safely shutting down and removing your old furnace. Our team follows strict safety protocols when disconnecting gas lines and electrical connections. We also handle the removal and disposal of your old unit in compliance with local environmental standards—no extra charges or messy leftovers.

Step 3: Preparing for Installation

Before installing your new unit, we inspect and prepare the installation area. If duct adjustments, thermostat replacements, or venting upgrades are needed, we complete those as part of the prep. We ensure that your new system is compatible with your home’s layout and wired correctly for optimal performance.

Step 4: Installation & Final Testing

Once everything is ready, we install your new furnace and connect all power, gas, and control lines. The system is then calibrated for efficient performance. We test airflow, temperature response, thermostat communication, burner operation, and CO safety systems to ensure your home is warm, safe, and energy-efficient from day one.

What Are the Signs That Tell Me It Is Time to Replace My Furnace?

Furnaces show signs when they’re on the way out. If your unit is over 15 years old, breaks down often, makes strange noises, or struggles to keep your home warm, it’s likely time for a replacement. Other signs include rising energy bills, poor airflow, and hot and cold spots in different rooms. If you’re unsure, we offer free assessments to help you make the right decision.

How Long Do Furnaces Last?

Furnaces can last 15 to 20 years depending on maintenance, model, and usage. Some electric models last longer, but they also use more power. Scheduling regular maintenance can help extend your furnace’s life and improve its performance over time.

Do I Need to Replace My Ductwork When Installing a New Furnace?

Not always. If your ducts are clean, well-sealed, and properly sized, they can be reused with your new furnace. However, if they’re damaged, leaking, or inefficient, replacing them could improve your system’s overall performance. We’ll inspect your ductwork during the consultation and let you know what we recommend.

How Much Does It Cost to Install a Furnace?

The cost of installation depends on several factors, including the size of your home, the type of furnace, energy efficiency rating, and whether ductwork or venting needs to be upgraded. At Mr. Furnace, we provide upfront quotes with no hidden fees. We also offer financing to help you spread out the cost.
