How Do I Know It Is Time to Replace My Furnace?

A furnace is usually ready for replacement when it is more than 15 to 20 years old, needs repairs every heating season, or no longer keeps rooms evenly warm. A cracked heat exchanger is another common reason to replace, since it can allow carbon monoxide into the home. Rising gas bills and frequent cycling are additional signs to consider.

What Size Furnace Does My Home Need?

The right furnace size depends on your home's square footage, insulation, windows, and ductwork, and it is determined through a heat load calculation. An oversized furnace short-cycles and wears out sooner, while an undersized one runs constantly without keeping up. A proper in-home assessment avoids both problems.

Is a High-Efficiency Furnace Worth It?

A high-efficiency furnace is often worth it for homes that use a lot of heat, because it turns more of each unit of gas into usable warmth. Higher-efficiency models cost more upfront and may need different venting, so the payoff depends on your gas usage and how long you plan to stay in the home. Your technician can compare options and prices.

How Long Does Furnace Installation Take?

Most furnace replacements are completed in one day. Projects that involve new venting, ductwork changes, or relocating equipment may take longer. Aire Serv of Kansas City North provides a timeline along with the upfront project price, and same-day service is available for all jobs.

Our Furnace Installation Process

A furnace installation with Aire Serv of Kansas City North starts with an evaluation of your home's size, insulation, ductwork, and venting to determine the correct heating capacity. Your technician explains efficiency options, including how high-efficiency furnaces vent differently than standard models. Once you approve the upfront price, the old furnace is disconnected and removed, and the new unit is set, leveled, and connected to gas, electrical, ductwork, and venting. The technician tests for gas leaks, checks the ignition sequence and burner flame, and measures temperature rise and airflow to confirm safe operation. Before leaving your Kansas City home, they walk you through thermostat use, filter replacement, and your warranty coverage.
