Furnace Replacement

Signs It’s Time to Replace Your Furnace

• Age (15–20 Years Old): Most gas furnaces last 15 to 20 years. If your unit is in or past this window, modern equipment will significantly improve reliability and heating performance.

• Escalating Repair Costs: If a repair quote approaches 50% of the cost of a new furnace, or if individual bills keep piling up, replacement is typically the smarter financial investment.

• Uneven Temperatures: Cold spots, drafty rooms, or a system failing to reach your set thermostat temperature on freezing days point to an aging furnace that can no longer keep up.

• Climbing Energy Bills: Furnaces lose efficiency as they age, burning more fuel to produce less heat. A high-efficiency replacement lowers monthly operating costs immediately.

• Frequent Breakdowns: Needing two or more service calls in a single heating season is a clear sign the unit has reached the end of its dependable lifespan.

• Safety Hazards: Yellow or orange burner flames, repeated carbon monoxide detector alerts, or cracked heat exchangers present active risks that require immediate replacement over repair.

Our Furnace Installation Process

A furnace that is improperly sized or installed will underperform regardless of how good the equipment is. Our process is designed to make sure you get the right system, installed correctly, the first time.

• Home Assessment and Load Calculation: We start with a Manual J load calculation to determine the exact heating capacity your home requires. This calculation accounts for your home's square footage, insulation levels, window quality and placement, ceiling height, air infiltration, and other factors that affect how much heat your home actually needs. Choosing the right size is the single most important decision in a furnace installation.
• Equipment Selection: We carry high-efficiency gas furnaces from trusted manufacturers and will walk you through the options that make sense for your home, your efficiency goals, and your budget. We explain the differences between equipment tiers in plain terms and will not push you toward a system that is more than you need.
• Professional Installation: Our NATE-certified technicians handle the complete installation to manufacturer specifications and local code requirements. This includes equipment setup and securing, gas line connection, electrical wiring, flue and venting installation, ductwork connections, and thermostat configuration.
• Safety and Performance Testing: Before we leave, we run your new furnace through a thorough commissioning process. We verify ignition, check the heat exchanger, test gas pressure and combustion, measure airflow and temperature rise, and confirm thermostat operation. You will not be left wondering if it is working right.
• Cleanup and Old Equipment Removal: We remove and properly dispose of your old furnace and leave your home clean. Haul-away is included in every installation.
