"Bad Decision"

1.0 rating
Very Unsatisfied

First off this review is by no means directed at my local dealer who services my unit and who I purchased it from. This is directed at American Standard. This is by far the worst purchase I have ever made. We bought the unit new and almost immediately had problems. We have at least 40 service calls. At one point unit broke 4 times in 3 weeks and 3 of those breakdowns was in a 9 day period. We have had all the boards replaced 4 times! Blower replaced 2 times now. Numerous relays, and a pile of other parts. The owner of our service company contacted American Standard to try and get us a new unit due to the problems but American Standard told him no that it was still under warranty. They didn't care about all the days and nights we roasted due to the heat or all the time my wife and I missed work so we could be home while the repairman worked on it. Even the repairman said it was junk and a lemon. Please to anyone reading this I highly recommend that you think twice before purchasing an American Standard product. Don't go through the same nightmare we have.

"Worked 9 years"

2.0 rating
Somewhat Unsatisfied

Unit worked good for 9 years then failed completely during the winter of 2018. Took 3 weeks to repair. Outside compressor failed but just made it within the warranty. Biggest problem was inside coil which I found out was just covered for 5 years. This is a $2000 item. Had pin hole leaks. Even though my initial contract said both compressor and coil was covered for 10 years they now tell me it is only on the outside unit. I am pissed and stuck. Local rep suggested I just braze the holes in the coil and fix for now. Could last another 1-2 years or more. This is crazy, pay $10,000 or more for a system that doesn't even last 10 years. I had older units (heat pumps) that lasted 20 years. NO MORE QUALITY. When I have to replace this unit it WILL NOT be with an American Standard or Trane for that matter

"Nothing but trouble"

1.0 rating
Very Unsatisfied

We had a 4a6h7036 installed at our house in sc last July; it's been nothing but trouble since then. 5 (five) visits from the installers so far, and another one scheduled. If there is a lemon law in sc, I'm going to trigger it. First the heating zone alert came on, repeatedly; it took 4 tech visits to "fix" that. They claimed it was software incompatibility. Now we've had some cold weather we find it has no (working) auto defrost feature, so it's a block of ice – and of course doesn't heat. What a pile of cr*p!

"American Standard are Junk"

1.0 rating
Very Unsatisfied

Have 3 units installed in 2010 and 2012. Two of the units have leaks in the reversing valve that will cost nearly $1,000 per unit to replace. Third unit has pin hole leak from factory weld. These units are junk and not worth the money. I will never have a house with American Standard again.

"Buyer Beware!"

1.0 rating
Very Unsatisfied

We purchased a American Standard Heritage 16 Seer heat pump in 2007 with a 10 year extended warranty. This unit has done nothing but cost me money in repairs and higher electric bills. We have had to replace three compressors and two evaporator coils in the time we have owned this "efficient" unit. Every time there is an extreme change in weather here in the Northeast it stops working. We are now running on emergency heat while we wait for yet another compressor. We are told it will take over a week to get the part all the while the meter is running on our electric. I have contacted Customer Service in the past to get a standard response that they will get back to me in 3-5 business days. Nothing, the dealer has repeatedly asked them to replace this lemon unit to just be told we will send more parts. I have written letters and never received a response from this company. I called again on Friday to be told to go back to the dealer, are you kidding me? Meanwhile no one knows why this keeps happening. The warranty will be up the end of this year and now we will be looking to replace this lemon of a unit because we cannot trust that we will be able to be comfortable in our own home in the coldest months of the year.

Other Heritage 16 Reviews

A reviewer on considering a new heat pump asks whether or not the Heritage 16 would provide ample humidity control in a southern region with mild winters. Several professionals on the site suggest the homeowner can't go wrong with the American Standard brand, adding that this unit is a quality heat pump. Others state that in this region the Heritage 15, with an appropriate thermostat and controls, can provide ample humidity control compared to the higher efficiency unit. Other professional contractors note that the heat pump's electronic demand defrost is a helpful featured compared to time/temperature defrost methods.

Many of the problems with the Heritage 16 cited on other forums seem to stem from installation issues. For example, a homeowner on has a newly installed heat pump that only puts out hot, never cold, air. Contractors on the site, after a series of questions, ultimately agree that the homeowner is dealing with a wiring issue that the installing technician needs to resolve.
