New Lennox higher efficiency heat pump in a 3200sq
May 01, 2025After careful consideration, I chose to upgrade to a new Lennox split heat pump system, with the CBK48MVT-71 as my air handler. - The installation was handled professionally and went smoothly. - I also decided to have the ducts cleaned, which was much needed due to drywall dust and debris left from the renovation. - The CBK48MVT-71 air handler is impressively quiet, a noticeable improvement over older systems. - It uses a large 4" filter, which I find convenient for maintenance and air quality. - My system is paired with a well-installed EL21KLV outdoor unit, and together they deliver consistent comfort throughout the home. **Comparison to Previous Systems** - In a previous home, I installed a 3-ton, 16 SEER single-stage system with the largest air handler that would fit in the space I had to work with without cutting drywall.. It worked well and was much cheaper upfront.i saw lower utilities, solid performance but less investment. - However, I opted for Lennox this time to maximize energy savings and efficiency, especially after seeing utility bill reductions in my last house from energy upgrades. **Overall Impression** - I’m very pleased with the CBK48MVT-71 air handler so far. It’s quiet, efficient, and seems to work well. Although I have not had it very long, it does keep the house where you set the temp. To utilize the functionality and the full range of the variable stages *installed a Lennox S40 thermostat. I'm interested to see the reliability and longevity over the life of this unit maintaining it well. At purchase I have a 10 yr parts warranty after registration. I will qualify for the 2000 tax credit with this unit. I have 1yr labor warranty. The maintenance plan through my installer is 17 a month after the first year. 23 if they bring and install new filters 2x a year - If you’re looking for a premium, energy-efficient HVAC solution and are willing to invest more upfront for long-term benefits, the Lennox CBK48MVT-71 is worth considering.

Great System
April 30, 2025The system is awesome! Although, I’m not in love with the thermostat as compared to the nest system. It may do more but it’s a lot less user friendly.
