Janitrol PG Furnace Reviews


1.0 rating
Very Unsatisfied

In 1995 replaced my furnace with a Janitrol Goodman as price was good, told by the installer “Janitrol” has been the name in commercial heating for years! Well, within a couple years was shutting down after furnace fired – ignitor or flame sensor bad. Continued having problems about every year after that, people I sold home to replaced it (Was only 10 years old!!!) Funny part is, brother has a duplex he put two of these in about the same time…both junk as were fine for first 1-3 years and problems on both ever since!!!

Still, products such as the PG furnace still have a presence on the web, a testament to their longevity. While reviews of the PG furnace are few, in general, Janitrol furnaces seem prone to issues such as bad igniters and regularly faulty flame sensors, according to the common complaints on online HVAC forums. Contractors on forums such as justanswer.com point out that in its heyday, Janitrol focused on low cost over high quality in its entry-level products.
