"20 years and still working"
All the reviews you read mean nothing. They all look the same, you hate it or you love it. I have a 20 year old Tempstar that works fine with only minor repairs over its life.

"You're all insane"
First of all, Heil and Tempstar are the same exact product, made in the same factory. They are both part of International Comfort Products - look it up. Second, 99% of product failures are due to improper install, so before you complain about the product you should make sure you are not getting the run around from your contractor (which you are). Lastly, to the review about the n8ms model furnace, the furnace does not cool. The evaporator coil, which is a completely separate piece of equipment, does the cooling in conjunction with the condenser outside. So the leak was not in the furnace, it was in the coil. Everyone who is complaining about the brand of equipment should only be complaining about how bad they got ripped off by the horrible contractor that they hired that botched the install.

"The Worst Unit-Air and Heat- EVER"
Here are the numbers on the Model..N8MSN0701412A Serial a104519709. This unit has been nothing but trouble since 2 months after installation. The air was not cooling. Finally they said there was a leak in a valve. Cost me $169 to have 4 pounds freon plus service call. Still not doing the job my 17 year old Heil, which was still in good working order however my son thought it best to replace the unit due to it's age. I now have a lemon tempstar. The heater just had 2 parts replaced which cost another $169. The heater works when it feels like it, it takes 3 or 4 efforts before the heater actually puts out heat. I rue the day I ever had this unit installed. Give me back my heil any day over this pile of junk.
