"Bad Condenser In Warranty"

1.0 rating
Very Unsatisfied

The unit is just 3 yrs old. The bottom of the condenser is bad and it needs to be replaced. When I called for warranty no one will help me get through. I have left 4 messages and no return calls days later. It's supposed to be on back order with no time in sight. I am going to go buy a goodman and install it. It's a shame when you buy something and it has an issue 3 yrs later you get ` sorry I can't help you. Goes to show you what kind of company Lennox is. They sell you something and don't stand behind it. Never again buy Lennox.

The unit installed in Fall 10/31/2017, used a/c in summer of 2018, February 2019 try and turn on and won't start. Call Lennox 800-953-6669 speak with m____, she refers me to Lennox premier dealer, who comes out $79 and says the compressor needs to be replaced, under warranty the part, but labor $750.00. Only used a/c five months. Call Lennox, I m sent to consumer affairs. Speak with Ph_____, she mumbles had to ask her name three times, she asks for the model, serial number, says this is a high quality product, but things happen, and I'll have to pay someone for installing the compressor. My advice is to close your eyes and pick any other a/c manufacturer not made in Mexico, and you will be probably better off.

"Evaporator coil failed"

1.0 rating
Very Unsatisfied

Worst experience I have ever had with a piece of hvac equipment and I have purchased well over 200 residential and commercial systems in my career. This was the first time I purchased a Lennox.

"Great unit"

5.0 rating
Very Satisfied

Great unit. I'm not sure about all the complaints. Probably used less than experienced companies or cheap companies. I have had mine about 4 years now and had zero issues. I paid a little more than some of the cheaper quotes, but cheap gets you cheap work. FYI, new home units are crap and they use the worst contractors that don't care about you. They just install as fast as possible and move to next unit. So it's not the brand's fault, it's the installing company.

Other 14ACX Reviews

A consumer on hvac-talk.com choosing between the 14ACX and another Lennox model with a higher SEER was told by several professional members that the units are almost the same, but the other unit is quieter than the 14ACX. Several members on other threads state that the Lennox is a well-built unit, although there were a couple of negative comments about it being made in Mexico.
