Lennox 13ACC Merit Air Conditioner Overview

The Lennox 13ACC Merit air conditioner is a discontinued split-system unit reaching 14.8 SEER with capacity ranging from 1 ½ 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 unit’s 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.

"Lennox not same quality as 20yrs ago"

Very Unsatisfied

We bought our home in the fall of 2005. Grand Homes our builder choose Lennox. Our home came with 1 Lennox 13acc 5 ton unit and one 3.5 ton unit for the upstairs. We have had to replace in the 5 ton unit first the capacitor, then 9 months later the compressor which automatically included the capacitor again, then the condensor coil leaked and evaporator coil leaked which cause the compressor to lock up. While Lennox come with manufacture warranty, you must still pay for the labor which totaled over 5 thousand dollars. We are now having our units changed to Carrier with a 10 yr warranty and 400.00 insurance plan for all labor over the next 10 year. Hard lesson learned.
