"Burl Milligan"

1.0 rating
Very Unsatisfied

The biggest mistake I made when building my house was installing Lennox heat pumps. I have 3 xp15 signature units ($ 18000). I have had numerous service calls. The most recent for a refrigerant leak (unit is less than 3 yrs old). I have replaced the motherboard & compressor before. Hell will freeze over before I purchase another Lennox item of any sort & I will do anything to dissuade anyone from purchasing any Lennox products. Any questions email me.
