"Trane XL16i"

4.0 rating
Somewhat Satisfied

Installed Trane XL16i, variable speed, hw media filter, Aprilaire #600 in May 2006. Been very pleased with unit. Replaced unit cost us $240 per month on budget plan w/electric co. New unit lowered our bill to $170 per mo. (2400 sq ft home).I Have hand eczema, and the heat pump does not dry my skin as bad as gas in previous homes. This winter temps. Are colder than previous years and will comment when temps fall below 10 degrees the heat pump shows signs of struggle, our thermostat is set at 65 and heat pump falls 3-5 degrees below the set temperature. I have Delonghi radiator heaters over the kid's vents to keep temps in their room warmer during this time. If you are located where temps fall in the 10 degree mark or lower, rec. To install back up furnace of gas/oil/ wood stove to keep your home warm. As with any brand of heat pump you have installed, the units are only as good as the contractor who installed it. Shop for a contractor first before choosing the brand, all units are built very well nowadays. We chose our contractor, and chose Trane due to the 10 yr warranty which other brands did not offer at the time.

"My new Trane Heat Pump and Furnace"

4.0 rating
Somewhat Satisfied

I just had today installed a xl16i heat pump along with an XV95 furnace for my St. Louis, MO climate. I'm very curious about some of the complaints listed below as I dropped a lot of dough on this sytem. I noticed one participant was from az. My understanding is if you think you may experience temp below 40 then you do need the air handler/furnace. Any thoughts?



"Good System"

5.0 rating
Very Satisfied

This is the best heating system I could ask for. I literally spent 300 dollars in 2007 to heat my 4000 sq ft home. I have the 16xli. My auxiliary (gas backup) does not kick on until I get below 10 Fahrenheit. I cannot believe the efficiency.

"Musty odor inside"

3.0 rating

I have had the XL16i heat pump for 6 months. I detect a musty odor coming from the registers, especially when the outdoor unit is in the defrost cycle. Does anyone experience the same condition, if so, what is the cause?

"Heat Pump nightmare"

1.0 rating
Very Unsatisfied

I had a Trane 16 XLi installed in my house with a completely new system. We were on emergency heat almost all of the time because the outside unit and blower weren't communicating. Numerous repair people came out even the local Trane rep and nobody could get it to work. Local Trane Reps here in Central il. refused to help – they would promise to take care of it and then never call back – I even wrote a letter to the company and received no response at all. it's a nightmare company that cost me hundreds of extra dollars in heating bills and wouldn't stand behind a brand new system.
