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.

Luxaire TG9S Furnace Reviews

"Reliable for all the wrong reasons"

1.0 rating
Very Unsatisfied

I purchased my furnace 5 years ago. I chose it because it met my price range and the heating and cooling contractor said it was a very reliable brand. It has broken down the last 4 years. Yes, this furnace is reliable – I can count on it breaking down every year. To date I have replaced 1 flame sensor, the condensation pan, pressure switches and, just last week, the blower motor. I do not plan on having this furnace in my home come next winter, as I’ve already started getting quotes on a replacement. I will never purchase a Luxaire product again.


"Works great, very efficient"

5.0 rating
Very Satisfied

A very nice machine, it runs quietly and very efficiently. I am very happy with the unit. I have had it for a year with no problems.


"Quiet furnace!"

5.0 rating
Very Satisfied

Since I have only just had the installation done, I am happy so far. I loved the Lennox that was 30-plus years old, but the pilot would not stay lit. I have ultimate confidence in my contractor, and they suggested the Luxaire, so we are hoping the furnace performs as well as the installer!

"Interesting fact"

2.0 rating
Somewhat Unsatisfied

Had the furnace 3-4 years, and the power vent seized. My wife and I have complained about the inconsistency of the heat and blowing cold air. We were constantly adjusting the thermostat. I sit near the furnace room in the basement and have thought that it seems the furnace had a mind of its own. The power vent was stopping and starting all the time, and differently. I could never figure out the pattern. I discovered the thermostat has cycle settings. The default of the thermostat was 5 times an hour. For this furnace (higher than 90% EFF) it should be 3 times an hour. Now it works normally, and the heat is more even. I also wonder if this contributed to the vent motor burning out prematurely.

"Do your research and spend a little money on quality"

1.0 rating
Very Unsatisfied

Only had the furnace 5.5 years (just outside the warranty) and now need the unit overhauled. I would never buy this product again, nor would I recommend it to someone who isn’t my friend. What I feel is wrong with the unit/product is the poor quality of its parts. The major money maker is not the sale of the furnace, it’s after the installation. This is where the money comes flowing into the dealer (during the maintenance of the unit). Parts are always breaking and/or cracking. Sure, there is a discount on the parts; however, there is still an out-of-pocket cost, a service call/diagnostic cost. If you do purchase this product, get the extended warranty and a service agreement! You should always have the unit maintained yearly; however, be prepared to spend extra money on maintenance!
