Luxaire TG9S Furnace Overview

As a member of Luxaire’s basic gas furnace product line, the Climasure Series, the TG9S Series is promoted by the manufacturer for providing efficient and quiet home heating. The single-stage heat units in this line offer 95.5 percent AFUE and feature self-cleaning Inshot burners, and a burner box designed to muffle operation noise and ensure low sound levels.

The TG9S also features durable performance, according to the manufacturer, with its aluminized steel tubular heat exchangers built to resist corrosion and cracks, a heavy-duty pre-painted cabinet, built-in shutoff sensors and a shut-off main gas valve for increased safety, and a low maintenance hot-surface ignition system.

With all 11 models in this series standing at only 33 inches tall, this product line is designed for installation in tight spots, such as closets, attics or garages. The TG9 furnace also is built using common service parts, allowing for low maintenance costs.

Very Unsatisfied

This thing sucks. Original furnace (keeprite) lasted 20 years not 1 issue. It finally blew and replaced it with a Luxaire unit. Had it installed on May 1, 2019, and has not worked more than 4 hours at a time. The contractor has been back to my house 4 times since he installed it. It has read 2 different codes, 3 flashing red light and now the new one, 6 flashing red lights. The contractor has gone back to the dealer and the dealer informed him that there is a faulty switch that needs to be replaced, that Luxaire knows about and he does not have the part in stock. Wtf. You sell a furnace that you know is faulty but don’t have the parts to repair it. I froze my ass off the first night. Spent 3 hours trying to fix it myself. This thing works for 2 to 3 hours and then shuts down. It has to be resent for 5 minutes then turned back on to get it working again. I have informed my contractor to remove it and install and different brand but I was informed that the dealer will not refund his money. Please do yourself a favor, stay away from this junk. I live in Canada and the weather has been a little wonky this year. Hot, cold. On the cold days, this house is like a freezer. I spoke to Luxaire head office and they will not help, not even calling the dealer. They took my money and washed their hands with it. I can’t believe I am out over 1000.00 with no other course to take. If I can help any other person from getting ripped off from this product I hope you guys pay attention it cheaper than paying cash.

Furnace/AC installed 2011. Furnace pressure switch went bad 2 yrs. Later & replaced by the installer-no charge. In 2018 draft inducer motor failed. Installer out of business & calls to 2 Luxaire dealers unreturned. Local dealer replaced & said he would turn in under 10 yr. Parts & labor warranty, but thought I’d have to at least pay labor charges. Unsure what to expect next. No problems with ac so far.

"So far very satisfied"

5.0 rating
Very Satisfied

The unit was installed in April 2016. Temperatures have been fluctuating from warm to cold on various days considering that we are moving into spring. I will say that the unit, which is a 60,000 BTU unit, compared to my last unit (40,000 btu) warms up the home much quicker (obviously). Now, because I’ve got a more powerful unit, we are noticing that the unit is a little louder than our last unit. But I guess that would be due to the increase in the BTU rating. Quick ignition, high efficiency rating, and more air flow through the vents are all positives. The real test will be next winter. We’re getting into spring now, so it’s a little too early to give accurate reviews. But, so far we’re very satisfied with our purchase.

"Luxaire furnace problems"

5.0 rating
Very Satisfied

I have been reading the reviews and felt I needed to respond. I have worked for the same contractor for 26 years and usually find a lot of problems with most brands of furnaces are installation errors. Most problems are improper duct sizing, flue and combustion air pipe sizing, and wiring of line voltage has to have proper ground neutral and hot connections. The main thing with Luxaire furnaces that I have found is that they were coming with clear plastic condensate collection pans located behind the draft inducer that would crack and leak. I believe Luxaire has figured this out because they have changed the box to a different plastic. We have had very few problems with the ones that we have installed.
