A furnace system is one of the most critical components of your home. Without a good system, you will be cold during the winter, spend way too much on your heating bill, and have poor comfort in your home. Knowing which bad furnace brands to avoid when purchasing a new system is important.
Based on research and personal experience, furnace brands to avoid include Westinghouse, Maytag, Frigidaire, York, Luxaire, and Coleman.

Furnace Buying Guide: What to Look for When Buying a Furnace
Today’s modern furnaces pollute less and provide more consistent heat than older models. Gas is the most common heating fuel, with natural gas and propane furnace models.
When it is time to repair or replace your furnace, most people call a qualified HVAC contractor for advice. Depending on the technician evaluating the system, you can get various opinions. It’s important to ask meaningful questions and obtain multiple quotes from different companies.
Many companies use certain brands exclusively. There’s nothing wrong with that; however, it can also tell you a lot.
The furnace needs to be correctly sized, or it won’t be able to keep your house warm when you need it most. An undersized furnace consumes more fuel as it runs longer than necessary to heat your home.
Most technicians will oversize the furnace to ensure it works during freezing temperatures. A bigger furnace will cycle on and off more frequently, putting additional wear on its component’s energy waste and potentially causing temperatures to fluctuate uncomfortably.
You may also require larger ducts if the ductwork isn’t big enough. Airflow can be noisy if ducts aren’t large enough.
Choose a contractor who will take the time to compute your heating requirements according to an industry standard like the Manual J HVAC residential load calculation from the Air Conditioning Contractors of America.
