Overview of the Merit
Today the Lennox Merit Series consists of two air conditioner models: the 13ACX and the 14ACX. The 13ACX has a SEER of 13 while the 14ACX can reach a SEER of 14 and is Energy Star-qualified. The manufacturer calls this series an “economical” option for efficiently cooling your home.
The Merit air conditioners employ a high-efficiency scroll compressor and direct-drive fan. This fan is precision-balanced for longevity and quiet operational noise. Merit units are designed to work with the manufacturer’s indoor dehumidification system, Humiditrol.
The outdoor coil transfers heat efficiently and is protected by a PermaGuard cabinet. This cabinet is made of heavy-gauge galvanized steel and has louvered coil guards. Furthermore, the base pan is protected from corrosion by its zinc-coating.

"Bad Evaporator Coil"
If you are considering purchasing a Lennox a/c until I'd advise doing research on their evaporator coils and class action settlement several years back. While the coil may be covered under warranty you need to cover labor and refrigerant out of pocket which is typically > $1000. Ours broke within 3 years and an extra $1500 on top of $5400 paid for the install. Beware!

"So far so good"
I know this I a cheaper unit but its 4 years now and its been great. After reading other reviews I guess I can expect some issues in the next 2-3 years. For now, it cools fine and it was reasonably priced.

"Lennox Air Conditioners Are Amazing"
We have had this air conditioner for going on 6 years, and we love it. We are a family of people who can never agree on how to keep the house, warm or cold or somewhere in-between. So over these years we have set it to 65 at night and woken up a few hours later to pump it up. Then again turn down the temperature a few hours later when the sun comes out and it gets hot outside. It detects when there's a temperature flux very quickly, as there have been times when someone in the house is a bit cold and opens a window in their room, and just a few minutes later the air conditioner comes back on. We make sure to have it checked once every six months, and we replace the filter every six months also. Another bonus is the filters are not expensive, and since we have kept up the maintenance on our Lennox air conditioner we have never had an issue with it. Nothing broken, nothing ever having to be fix or replaced. It wasn't expensive to begin with and again, 6 years later and it's still going strong, It was worth every penny.

"Ten Years and Running Smooth"
I am very satisfied with this Lennox unit. We live in a very hot climate and it has never failed to keep up with the heat. If I ever buy another air conditioner, it will be a Lennox.

"Bad product - don't buy!"
The unit was installed new on 7/2/2014. It stopped cooling on 9/23/2014 (less than 90 days). The tech said it was low on coolant and possibly had a leak, and he would perform a search. On 9/25, he searched for a leak. He said it was a bad coil and he would order a replacement. The outside unit kicks on loudly and the unit runs loudly. I complained to the tech/company several times to no avail. The company that installed the unit was helpful after I wrote an email about the poor unit & their service, and about not following up with me when the unit first broke down. They did provide an all-inclusive 10-year contract that states I will not have to pay any amount for any future problems. They also provided a complimentary one year contract on both of my units. Now it's winter and the unit doesn't warm the room as well as my old unit did. I was comfortable with the thermostat set at 68 on the old unit, but the new one requires at least a setting of 76. This is ridiculous. My last unit was a Trane. Don't buy this product.

This product is not reliable or efficient. I have had nothing but problems with this product from day one. I wish I had gone another brand. Because of lack of quality control in this product has cost me (electric bill, time from work etc.). Bottom line, I should have done much more research than I did.

"13ACD-030-230-01 and 13ACD-042-230-01"
My two ac units came with our new home in 2006. On 5/7/10 a bad condenser motor had to be replaced on the upstairs for $305.00. On 4/29/11 Repaired a leak on the e-Coil on the downstairs unit for $346.00. On 7/30/12 I had to replace a 5mfd capacitor and a blower capacitor for $487.00. Seems that either Lennox' products are inferior or the repair company is taking me for a ride. Which is more likely?

"Don't Expect Lennox to Help"
Ran fine and efficient for 3 years but freon leaked out over time. Lennox says even though it has a 5 year part warranty, freon is not covered. Repair tech discovered valve coil separated and managed to solder it and that cost $550 for new freon. Tech said it was a defect by manufacturer but no matter to Lennox, not covered. After the third repair I elected to get an extended warranty that covers any and all repairs just to protect myself from trying to get Lennox to back their sorry product. I have discouraged several friends and family members from buying Lennox.

Beware of this company. I have seen 5 homes on my street with the same unit all starting to die around the same time. Seven years is not a longtime for an a/c unit compressor.

"Excellent air conditioner!"
Its an excellent air conditioner. I am very happy with the price I paid for it.A shorter warranty is especially worth considering if you don't expect to stay in your home for a long time. Its small size also makes it fit in our medium sized house. An oversized air conditioner costs more to buy and cycles on and off more frequently, reducing its efficiency. It uses just the right amount of electricity.

"Have had issues with these units starting in year Four!!"
I would seriously would rethink any Lennox product in the future and warn homeowners and potential homeowners to be wary. Merit Series units were placed in a $500,000 home by James Customs Homes and I later learned this was a cheap out option. We thought we had a system that with proper maintenance give us at least a decade of worry free service. Hardly, we started replacing parts in as little as 3 1/2 years... mother boards, switches etc. Everything is proprietary part wise, so don't look for your regular HVAC tech to have parts. Everything has to be ordered through Lennox and prices are steep. Can you say revenue stream? We're now in year six and frankly it's more problems. The likelihood of spending thousands of dollars after just 6 years is sickening. Arm yourself with knowledge before buying any product from Lennox. If you're buying new construction, do your homework and make the builder switch out systems if they want to make the sale. I strongly suggest buying equipment where parts can be carried by anyone thus prices for maintenance is lower. Stay away from proprietary systems that forces only their specialty parts. They sell it as ensuring quality, but understand it's a rich revenue stream for years to come for them. As a Real Estate Broker, I intend to educate my clients to make sure they understand what they're buying and what to expect.

I bought a new house in 2006 and the builder installed a lennox M/N 13HPD-048-230-01 ac/heat pump unit. For tha last 2 years I have spent approximately $350 each year on substandard parts. Last year the repair contractor found a leaky start capacitor. This year the fan motor in the outside unit quit working. The estimated cost to replace the fan motor is $350. The season is just starting so I am afraid of what might be next with a 5 year old unit.

We bought a new house and through the builder, we brought Lennox 13acd. The first time we turned it on, it was not working. According to the dealer, the compressor is not working. "This is a "new" air conditioner and it needs to replace the compressor" ???? I called Lennox and all they said is, 'Don't worry, your dealer will look after it!!". Well, point is, this is a "New" air conditioner and it is not working. Why would they call it new when it doesn't work in the first place? In addition, in our old house, we used "RUUD" air conditioner and never had any problem for the past 16 years. I meant no problem, not a single repair call to the dealer or to their head office. If we had a choice, we would definite buy a "RUUD" again. June/2010
Other Merit Reviews
Reviews on Lennox Merit air conditioners are varied. One contributor to an hvac-talk.com discussion forum suggests that this is a bottom-of-the-line unit. He cites problems such as an exposed coil, a stamped top and noisy operation. However, a homeowner posting a review of the product says that the “solidly built” 13ACX is a good value for what it is. Dealers emphasize the need for homeowners to work with a well-respected dealer for a good installation and to understand the details of the warranty.
The Lennox websites indicate the unit is covered by a 5-year limited warranty on covered parts and homeowners may be able to purchase a 10-year limited extended warranty. Online registration is required for full warranty terms to apply. Homeowners should discuss warranty information with the dealer for clear details and consider additional purchases that are needed for the warranty to apply.
