Enjoying the new system.
November 15, 2025I was a bit hesitant about buying a new system but so far I don’t find this new system working all the time like our old unit which was 20 years old. The true test will come when we see our electric bills in the future. A lot of promises and we shall see but so far it’s going well. This brand has been around for a long time and really hope they have kept up the quality and not cut corners. In closing so far so good and hoping it will deliver for the next 20 years.

Great System
November 14, 2025We had to install a new AC in the height of Arizona summer. Lennox system provides better cooling than our old system. Many thanks to our local sales/installation experts - Wolfgangs Cooling. This group did an amazing job of efficiently sourcing and installing the optimal new system for us.
