How much does a furnace cost for a 1500 square foot house?
For example, a 700- to 1,500-square-foot home will require a BTU rating between 40,000 and 60,000, which will cost between $2,000 and $3,000. A furnace for a home ranging in size from 2,000 and 5,000 square feet will need between 125,000 and 150,000 BTUs and will cost in the neighborhood of $3,300 to $6,500.
Can you replace just the heat exchanger?
If parts and labor are still under warranty, you can probably replace just the exchanger for now. If you’re covered for parts but not labor, you can further discuss the pros and cons with your HVAC professional.
What does a cracked heat exchanger flame look like?
Normally, your gas furnace has a steady blue flame. If your burner has a moving yellow flame, it could be dirty or have a cracked heat exchanger. Flames that flicker, lean, dance around or change when the fan comes on, are possible signs of a cracked heat exchanger.

How long do Goodman heat exchangers last?
The heat exchanger will typically last for the life of the furnace, which can be anywhere from 10 to 15 years or more.
What is the difference between a furnace and a heat exchanger?
Furnaces. Furnaces generate heat by combustion of natural gas or via electrical resistance. A heat exchanger in the system transfers this heat to air that is then distributed throughout the house via a system of ductwork.
Can you clean a heat exchanger?
Cleaning-In-Place (CIP) equipment can clean plate heat exchangers without disassembly. CIP is a combination of time, temperature and concentration. CIP provides both chemical and mechanical cleaning to the heat exchanger. If system configuration prohibits CIP, operators must perform manual cleaning.
How do you test a heat exchanger performance?
The simplest indicator of the performance of a heat exchanger is the temperature change of the fluid under consideration. From our high school lessons on thermodynamics, we can recall that the rate of heat transfer is the product of the rate of heat capacity and the temperature change.
How long do furnaces usually last?
THE AVERAGE FURNACE LIFESPAN A well-maintained furnace can last at least 15 to 20 years, but completing annual maintenance and being diligent with repairs can extend its life even longer.
Can furnaces cause carbon monoxide?
