How Do I Know When to Replace My Furnace?

A furnace usually needs replacement when it's 15 to 20 years old, needs frequent repairs, heats unevenly, or has a cracked heat exchanger. Rising gas bills, a yellow burner flame, and excess dust or dry air can also point to an aging furnace. Our in-person estimate puts the price of a new furnace side by side with the cost of keeping the old one running.

What Does AFUE Mean for a Furnace?

AFUE, or Annual Fuel Utilization Efficiency, measures how much of a furnace's fuel becomes heat for your home. A 96% AFUE furnace turns about 96 cents of every dollar of gas into heat, while many older furnaces are rated at 80% or less. Higher-AFUE furnaces cost more upfront but can lower heating bills, which adds up over long Northeast Ohio winters.

What Size Furnace Does My Home Need?

The right furnace size depends on your home's heat loss, which is shaped by square footage, insulation, windows, air leaks, and ceiling height. Furnaces are rated in BTUs, and choosing one based only on the old unit's size can repeat a past sizing mistake. Aire Serv of Lakewood-Avon includes a heat loss evaluation in its in-person estimates to help match the furnace to your home.

Should I Replace My Furnace and Air Conditioner at the Same Time?

Replacing a furnace and air conditioner at the same time often makes sense when both are more than 10 to 15 years old, because the blower and indoor coil can be matched for better efficiency. It also means one installation visit instead of two. If your AC is relatively new, replacing only the furnace is usually fine. Financing is available for single or combined installations.

How Long Does Furnace Installation Take?

Most furnace replacements take about one day when the new furnace fits the existing space, ductwork, and venting. Switching to a high-efficiency furnace may require new PVC venting and a condensate drain, which can add time. Your technician will explain the expected schedule during your in-person estimate.

Why Westlake Homeowners Choose Us for Furnace Replacement

A new furnace is a long-term purchase. Here's what makes the process easier.

Aire Serv of Lakewood-Avon gives furnace replacement estimates in person, so the technician can evaluate your home's heat loss, inspect the ductwork and venting, and see how the current furnace is sized. An oversized furnace short-cycles and wears out faster, while an undersized one struggles on the coldest nights. The visit also shows whether your existing ductwork can be reused or needs changes. If you'd like a starting number before the visit, limited phone estimates and an approximate estimate on our website are available to Westlake homeowners.
Financing is available for furnace installation, which helps when an old furnace fails in the middle of winter and replacement can't wait. Spreading out the cost makes it easier to choose a higher-efficiency furnace that lowers gas bills over time. Veterans, military members, first responders, teachers, and seniors also get 10% off any service. Your technician can walk through payment plans at the estimate so the decision isn't rushed.
The Neighborly Done Right Promise® covers every furnace Aire Serv of Lakewood-Avon installs. On top of that, we put a warranty on our own installation work, and you can add extended coverage for longer protection. A furnace can serve your home for 15 to 20 years, so knowing the installation itself is covered matters as much as the manufacturer's equipment warranty. Keep your installation paperwork handy, since many manufacturers require product registration soon after installation to activate extended equipment coverage.

Our Furnace Installation Process in Westlake

Furnace installation with Aire Serv of Lakewood-Avon begins by shutting off gas and power, disconnecting the old furnace, and taking it out of the space. Next, the technician sets the new furnace, connects it to the existing or modified ductwork, and connects the gas line, which is then checked for leaks. Venting is installed to match the new unit, since high-efficiency furnaces typically vent through PVC pipe while older models use a metal flue. Wiring, the thermostat, and a condensate line for high-efficiency models are hooked up after that. Then the technician fires the furnace, checks the burner flame, gas pressure, temperature rise, and airflow, and confirms the safety controls work. Before leaving, they show you how to change the filter and use the thermostat, so your Westlake home is ready for winter.
