Overview of the 14ACX

The Lennox 14ACX is a single-stage air conditioner with an efficiency rating that meets or exceeds 14.00 SEER. It features a scroll compressor and a high-efficiency outdoor coil which provides increased heat transfer. A direct-drive fan is designed for quieter operation and keeps sound levels as low as 76 dB. The PermaGuard cabinet is constructed of heavy gauge galvanized steel with baked-on powder finish and a zinc-coated steel base to provide protection against rust and corrosion.

"Failed after one summer - terrible customer service"
Built new house and the AC unit worked for the first summer. Turned AC on for the first time this May and no cold air and the unit was making terrible noise. HVAC repairman said it needed to replace the compressor and the part was covered but not the labor. Then they charged me $250 to replace the Freon that was not a part. Well Freon sure is not labor. Calling Lennox, wait times are over an hour and they just tell you to fill out a form and they will get back to you. It took two months and they just said too bad. Tried calling back to get a supervisor to speak with and after waiting another hour they just transfer you to a supervisor's voicemail but he never calls back. Stay away from Lennox.

"If only I could give zero stars"
System worked for one summer. At the start of the second summer it failed. Now I know why they don't offer any service warranty and only offer parts warranty for one year. I am now having to spend$1300 to get a brand new air conditioner repaired after it worked for only one summer. Their "customer support" was completely useless as the guy, **** *********, just kept talking like he was reading from a manual rather than hearing my concerns. Run the other way.

"Contractor grade, low end, but has been fairly reliable."
About what you'd expect in upper-median-priced new construction (2007). It is a 14 SEER unit and has thus far (9 years) provided reasonable performance. We had to have the "a" coil replaced at 4 years. The coil itself was under warranty though we had to pay the $2000 labor. Yes, it was a fairly laborious task in a scalding hot attic, but $2000 still seemed a bit much. We checked around though and learned that the labor price was not out of line. Yesterday (unit is now 9 years old) I had to replace the fan/compressor motor-start capacitor. This is an approximately $15 part (cde # 10035-12) that you can get from Amazon & replace yourself or else you can pay your A/C guy $289 to do it for you. I did mine myself, took 5 minutes, but can understand how most folks would be intimidated by technical/mechanical/electrical stuff & pay someone to do it for them. Overall it's been a good unit for a small home (1600 square feet) but now at 9 years old it likely hasn't much service life remaining. I'll be happy if I get another year or 2 out of it, which in reality is a typical replacement interval (10-12 years) for most major appliances. It cools our home very well and slowing the blower fan down to medium speed (as recommended by our A/C guy) made a grand improvement in keeping us comfortable in the hot South Texas summers. Considering it's a low-end model, it has performed well & thus is probably good bang for the least buck. The early failure of the original coil was the only disappointment.

"So far so good"
Great unit, cools well. The only concern is with the short run times but for the most part it's a great unit.

"Has a mind of it's own."
I've owned my air conditioner for going on 3 years. It seems like it has a mind of its own. Even when I set the air conditioner for a specific temperature, sometimes it will cut on and be successful, but sometimes it just runs and runs without doing any good at all. It has never been looked at to be repaired or replaced, but I am not sure that anything could be fixed; it seems like it is constantly running without doing its job. I would not buy this brand of air conditioner again. Although, I shouldn't be surprised that it doesn't work very well, because it is a budget brand, after all. I haven't had any other issues with it. When it does work, it works very well and very fast, but taking the chance of it not working very well on days when it is very hot or very cold is not my idea of getting a bargain.

"Felix Pan"
Purchased Centex brand new house on 10/2011. Came with Lennox a/c model no. 14Acx-030-230-11. 5/11/2014 a/c stopped blowing cold air. Called a/c company. Cost me $600+ to install start kit. 410A refrigerant very low. Tech partially charged refrigerant the a/c . Cost me $800+ for leak detection. On 6/27 a/c tech found leak on the interior of the Condenser Coil . a/c cooling down to 1. Almost empty. Lennox would only cover part. I have to pay labor which was way too much in addition to what I already paid to the a/c Co. I'd rather buy new unit of different brand. I don't trust Lennox anymore. It would just cost me more money if I stayed with Lennox. I know there is a class action suit filed by different Attorney against Lennox for Evaporator coil leak. On 7/1/2014 purchased Goodman a/C. 14 seer, 2 1/2 ton, 410a refrigerant. Warranty: Lifetime compressor, 10 yr parts- only good on purchase made on 7/1/2014. Installed on 7/2. Also a/c tech sealed all vents inside the house and sealed ducts up in the attic. Price: $5770.00. Issue with Lennox, I will find an attorney.

Had a Lennox Central Air Conditioner unit(4 tons). The condenser coil on the outside unit has a leak. All the refrigerant had to be replaced, plus labor to the tune of over $1000. Yes, the warranty covered the part of the coil, but the labor and the refrigerant is not covered. I had two different licensed A/C techs out and they both said that the condenser coil almost never leaks. It is always the evaporator coil. They said it was most definitely a manufacturer defect that caused the problem. I talked to a Lennox person and he was of no help at all. He was actually a little snobbish. If they are supposed to be such good units, then why did mine fail in just over two years? Well, actually it failed before 2 years, but it took a while for all the refrigerant to leak out. Without that happening, we didn't even know there was a problem. Lennox units are not very good. Stay away. We only used them because the builder put them in. I would invite any Lennox person to try and refute my story. The manufacturing number of my crappy unit to back up my story was: 14acx-048-230-01 and the Serial number was 5807b35067. So, if a Lennox guy is reading this look it up and your computer and try and figure out why you build such crappy A/C units.

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.
