Very Satisfied

This product was purchased by Citizens for Citizens in Fall River, Massachusetts, and Eagle Energy Systems won the bid to install the furnace. CFC helps low income families to with home energy improvement upgrades. I am very happy/pleased with this nonprofit organization for footing the cost of your product. I hope if ever we get the finances for the cost of the air conditioner system, I will definitely add it. It would be a dream come true…at least we are halfway there. Thanks for a high rated workmanship equipment/product. Jim Fontes

"My York furnace is a lemon"

1.0 rating
Very Unsatisfied

We purchased a new York furnace in December, 2009. By October, 2010, it had its first of many breakdowns. Our contract states 10-year warranty on parts and labour. York is now claiming our parts warranty is only for 5 years. The amount of times we have had to make repairs on this machine is ridiculous. I’m at the point where I am going to throw out this machine and eat the cost of buying a new furnace. I will never recommend York furnace. I will also tell my friends, family, co-workers and any that will hear this story about not buying a York furnace.

"Dual Fuel review"

5.0 rating
Very Satisfied

We had a York model TM9v120D20MP11 propane furnace paired with a York heat pump (no model number) installed by the Petrie Company out of Cookeville, Tennessee. We have been pleased with the two units (quiet, seem more efficient,no problems). However, the equipment is only as good as the installation and service, and in those two regards we cannot say enough about the Petrie technicians who installed both units. They were quick to install the units, polite, made sure we understood how to work them, made sure they complied with an energy audit we had via TVA prior to installation, and were pleasant to work with. I would recommend the contractor and York products to anyone. We will repeat the process when we replace the heating/cooling unit for the lower half of our house.

"York TM8V is working fine, installed 1 week ago."

5.0 rating
Very Satisfied

The furnace is the regular type furnace found in average homes in New Jersey. The TM8V has two stage burners and the variable (3 speeds) fan motor gives better temperature control in the rooms than the old 1993 single stage burner and single speed fan I had before. There are not a lot of “bells and whistles”, buttons/levers to set or adjust on the furnace. Overall I’m happy with this furnace during the first week of operation. I might have jumped for the TM9V had the prices offered by the installer been a lot closer. I will see in the middle of next month, when I get the gas/electric bill, whether I get the savings the installation company claimed I would get.

"York duel fuel installation"

5.0 rating
Very Satisfied

The York LX series high efficiency equipment is coupled with a York high efficiency heat pump in a duel fuel setup. We use propane gas, and I now use 75% less propane. My electric bill, even though the heat pump runs more, is actually 21% less! York equipment and our certified York expert are remarkable.

Other LX Reviews

One user at GardenWeb.com describes the York LX furnaces as “nice”. The reviewer appreciates the compressor jacket which makes the unit quieter. Another comment from doityourself.com states that the York LX furnaces has the ECM feature which allows owners to get constant air circulation by running the fan on a low speed. This benefit is more noticeable in multi-level homes.
