"Never ever ever purchase"
This is without a doubt the worst piece of equipment I have ever owned. I have had this furnace now for 5 heating seasons and am still trying to get the issue with pressure switches resolved. The frigidaire tech has no interest in inspecting this worthless piece of junk, he prefers to come up with "solutions" for my furnace guy to try. Not one of his ideas have made any difference. Does this company not care about its customers? Stay away from this product. I am disheartened to read other reviews and find that contacting frigidaire directly will most likely prove futile.

"Contractor choice is key"
Look for a professional company that will search out all your needs/wants with a new furnace. My contractor started out with actually showing up on time, which is very unusual in Muskoka, next I received a detailed quotation including heat loss analysis which only one contractor provided. This contractor took the time to ensure all my needs were met and even registered the product once completed, oh ya, the furnace, Frigidaire's modulating furnace, Awesome!

I had my furnace "red tagged" because the heat exchanger was gone. I called another contractor to have it checked and there was nothing wrong with the furnace, it was just old and did not have to replace it. A year later I called the same contractor and because my furnace was 21 years old I had it replaced. The Frigidaire FG7MQ unit he put in saved me money on my gas bill and was very quiet. I do not have to turn up the tv when the furnace turns on. Thanks Luke.

Other FG7MQ Reviews

One post on the Garden Web forum stated that the Frigidaire furnaces provide extra comfort at both the low and high stages. The FG7MQ model has a dual-stage feature.

One Frigidaire gas furnace owner writes on doityourself.com that his furnace will only operate properly with the cover removed. A contractor suggests removing the flame sensor and cleaning it with fine-grain sandpaper. This action solves the problem; several other readers report this has helped their furnaces function properly. One expert suggests that this cleaning should be done annually.

Hvac-for-beginners.com ranks this Frigidaire furnace as having four out of five stars. The FG7MQ, with its iQ drive, is the top of the line of the Frigidaire gas furnaces, and the communicating thermostat is a real plus for establishing comfort in the home.

A homeowner poses the question on justanswer.com of whether there is an easier way to clean the heat sensor than scrubbing with sandpaper or steel wool. A contractor suggests carburetor cleaner, but the homeowner says even that solution has not worked. The problem with charring and oxidation on the flame sensor seems to be the main issue mentioned online with Frigidaire gas furnaces.


The FG7MQ is available in different models which vary in efficiency and capacity.

Model Number AFUE BTUs per Hour
FG7MQ 060*-VB 97 60,000
FG7MQ 080*-VC 97.2 80,000
FG7MQ 100*-VC 97.4 100,000
FG7MQ 120*-VD 97 120,000

FG7MQ Warranty

Frigidaire offers a 10-year warranty on all parts for the FG7MQ gas furnace. The entire unit will be replaced within 10 years if the heat exchanger fails. Owners must register their furnaces online within 60 days of purchase in order to receive this coverage.
