Comfort-Aire Furnaces — Frequently Asked Questions
Common questions about buying and replacing Comfort-Aire furnaces in Chicago
Q
Where can I buy a Comfort-Aire furnace in Chicago?
Consumers Supply Company at 1110 W. Lake St. in Chicago carries Comfort-Aire furnaces for residential and light commercial applications. The store is open to the public — homeowners, landlords, and building owners are welcome to walk in, no contractor required. Call (312) 666-6080 to discuss your heating situation and confirm availability before making the trip.
Q
What is Comfort-Aire?
Comfort-Aire is an HVAC brand manufactured by Heat Controller, Inc., a Michigan-based company that has been producing heating and cooling equipment since 1937. The brand makes gas furnaces, air conditioners, heat pumps, and related HVAC equipment for residential and light commercial use. Comfort-Aire is a value-oriented brand known for solid performance and reliability at a practical price point, making it a popular choice for rental properties, coach houses, and budget-conscious homeowners in the Chicago area.
Q
What types of Comfort-Aire furnaces does Consumers Supply carry?
Consumers Supply carries Comfort-Aire gas furnaces for forced-air heating systems. These are the standard upflow and counterflow configurations used in Chicago homes and apartments with ductwork. Comfort-Aire furnaces run on natural gas and are available in a range of BTU outputs to suit different building sizes. Call (312) 666-6080 to discuss which model and output is appropriate for your application and to confirm current stock.
Q
How do I know what size Comfort-Aire furnace I need?
For a direct replacement, the simplest approach is to match the BTU output of the existing furnace — if your home has been heating adequately and you’re satisfied with comfort levels, replacing with a similarly sized unit is the right call. The model number on your existing furnace will show the BTU rating. Bring that information when you call or visit Consumers Supply at (312) 666-6080 and we can help identify the right replacement model.
Q
How long does a gas furnace typically last?
A well-maintained gas furnace typically lasts 15 to 20 years. Annual service — cleaning the burners, inspecting the heat exchanger, checking the igniter and flame sensor, and replacing the filter — is the most important factor in maximizing furnace life. If your furnace is over 15 years old and starting to show reliability issues or efficiency decline, a replacement before an emergency failure in the middle of a Chicago winter is worth seriously considering.
Q
What AFUE rating should I look for in a furnace?
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts gas to heat — an 80% AFUE furnace converts 80 cents of every dollar of gas into heat, with the remaining 20% lost through the flue. Standard efficiency furnaces run at 80% AFUE, while high-efficiency condensing furnaces achieve 90–98% AFUE. For Chicago’s cold winters and high gas usage, the energy savings from a high-efficiency unit can be meaningful over the life of the furnace, though the upfront cost is higher and installation requirements differ. Comfort-Aire offers both standard and higher-efficiency models — call (312) 666-6080 to discuss the options.
Q
What are the signs that my furnace needs to be replaced?
The most common signs are age over 15 years, increasing frequency of repairs, uneven heating throughout the home, a noticeable rise in gas bills without a change in usage, unusual noises like banging or rattling during operation, and a yellow or flickering burner flame rather than a steady blue one. A yellow flame in particular can indicate a cracked heat exchanger, which is a safety concern that warrants immediate attention from an HVAC technician. If your furnace is showing multiple warning signs, replacement is almost always more cost-effective than continued repair.
Q
Is Comfort-Aire a good furnace brand?
Comfort-Aire is a reliable, practical brand that delivers solid performance at a competitive price. It is not positioned as a premium brand, but for rental properties, coach houses, and homeowners looking for a dependable replacement furnace without paying a premium for name recognition, Comfort-Aire is a well-regarded choice. The brand has been in the HVAC business for decades and its products are widely serviced by Chicago-area HVAC contractors.
Q
Can a homeowner purchase a Comfort-Aire furnace directly from Consumers Supply?
Yes. Consumers Supply is open to the public — homeowners and building owners can walk in and purchase a Comfort-Aire furnace directly, no contractor required. Many customers purchase the unit themselves and have a licensed HVAC contractor handle installation, which can help manage overall project cost. Stop by at 1110 W. Lake St. or call (312) 666-6080 to discuss which model fits your application.
Q
Does a Comfort-Aire furnace need to be installed by a professional?
Yes. Gas furnace installation involves gas line connections, flue venting, electrical wiring, and integration with the existing ductwork — all of which require a licensed HVAC contractor or plumber in Chicago. Improper installation creates serious risks including gas leaks, carbon monoxide buildup, and fire hazards. Purchasing the unit yourself from Consumers Supply and supplying it to your contractor is a practical way to control costs while ensuring the installation is done correctly and safely.
