Working as Expected
July 09, 2025Lennoxx AC, 2.5 ton, rated "Good". I had to do an upgrade to the thermostat because the one that came with the unit was unreadable because the digital window was so small. AC working as it should and I was able to keep the temp at 77 instead of 74-75 on my old unit. The unit was just installed 6/5/25 hopefully I'll get years of use out of it.
