Review of my new Lennox HVAC system

November 02, 2025

So far so good have had the system for a little over a month and the unit has worked well i have had the chance to use both the heating and cooling part of the system. My old system was a top of the line 2 stage Carrier which worked well for over 25 years and being a 2 stage was very quiet but quiet comes with a price which is approximately 2000 dollars more and at this point in my like I just couldn't justify (AKA CHEAP) One other note is build quality the Carrier appeared to be built better but i guess its the sign of the times hopefully this unit will last 25 or more years but i highly doubt it. The install was donre by Kenders heating and cooling and i couldn't have asked for a better bunch of guys they arrived on time and completed the swap out in 9 hours they answered all of my questions snd explained labor and warranty one thing i dont like is the ONLY 1 year parts and labor which i think should be 3 years parts and labor but once again nothing is like it use to be this is my first experience eith a Lennox product and i hope i made a good choice
