Overview of the 13ACC Merit

The Lennox 13ACC Merit air conditioner is a discontinued split-system unit reaching 14.8 SEER with capacity ranging from 1 Ĺ to 5 tons. Around its launch in 2002, the unit was Energy Star-qualified, had earned the Good Housekeeping Seal and was considered by the manufacturer to be very reliable due to the simplicity of its few moving parts.

The 13ACC resists rust and corrosion due to its heavy-gauge galvanized steel cabinet, which has a baked-on finish. A Copeland scroll compressor helps optimally control the unitís air temperature. The direct-drive fan is balanced to ensure slow function and, therefore, quiet operation.

In order to protect the unit from damaging moisture, drainage holes are placed in the base pan, and the condenser coil is protected by a non-corrosive PVC-coated steel wire guard. Also, if the system needs to be accessed, the reusable service valves enable the unit to go into a preferred pump down cycle instead of being pumped out.

For pressure equalization, this unit is designed for fixed orifice systems. However, expansion valve kits can be ordered to help the unit attain higher refrigerant effect, capacities and efficiencies.

"Bought a lemon"
I would not buy a Lennox again. Our 3-year-old unit is not working. We have already spent over $1,000 in labor (a new compressor and disconnect box). Lennox refuses to replace the unit and will not reimburse for the labor costs. It's been 3 weeks of sweating and we're not any closer to getting the thing fixed. Do not buy a Lennox !

My neighbor replaced his 13yr old a/c and furnace with new Lennox units.He advised another neighbor about how pleased he was with Shumates service and that neighbor got the same units from Shumate. That neighbor was also very pleased with Shumates service and advised me. I then had Shumate install the same units at my house (all the houses in this subdivision are similar). The workmen arrived on time and completed my installation in 4 hrs. They were neat, efficient and cleaned everything up. They were totally professional, explained everything to me and I was completely happy with their work. I will recommend Shumate to others in my sd who are having trouble with their old systems. My gas and electric bills are noticeably lower.

"Compressor Only Lasted 6 Years"
I am not pleased with this air conditioner. The compressor on my new Lennox went out in 6 years. I bought a new house so I wouldn't have to deal with problems like this. What a shame, the Lennox company can't make a quality product.

"Outdoor fan broke down in three years out of ten years warranty, Dealer denying warranty"
I don't have a problem with the previous ac I upgraded my furnace to high efficiency and decided to do the same thing with my ac thinking Lennox is a great product with good dealers selling the product but I was wrong. My ac out door fan broke down only 3 years out of ten year warranty dealer denied warranty asking me to pay for the part $420.00 + 111.00 diagnostic test plus labor $220.00 and kept ditching me to instillation time too much stress,its going on Wednesday evening until Friday evening. Company finally honor only warranty in parts but I still have to pay the rest. Hope its not going to break again.
