Super Efficient and Eco-Conscious Choice!
11/13/2025As an environmentally conscious homeowner, I appreciated the green R454B refrigerant and Energy Star certification. The variable speed technology optimizes energy use, and the SEER2 rating of 18.6–20 has cut our electricity consumption by nearly 25%!

Satisfied!
10/25/2025This system cools our 2,200 sq. ft. home evenly, thanks to the variable speed compressor that adjusts to each room’s needs. Satisfied!

Great product
09/13/2025I upgraded to this 2–3 ton variable speed unit last month, and it’s been a game-changer! The inverter technology adjusts heating seamlessly, and I love how quietly it runs (indoor unit is barely audible at 49 dB). Installation was smooth with a certified technician, and the multi-position air handler fit perfectly in my attic. Highly recommend for anyone wanting comfort without the noise or high costs.

owerful Heating and Cooling
08/21/2025Living in the Midwest, we need a system that can handle both scorching summers and freezing winters. This unit delivers! It cooled our home effortlessly at 125°F and kept us warm during a -4°F cold snap. The auto-defrost feature prevented icing, and the R454B refrigerant is a eco-friendly bonus. The 5-year warranty on parts and compressor gave us peace of mind. Though professional installation is a must, it’s worth every penny for year-round reliability.
- P
Flexible Installation
07/24/2025Our basement layout made HVAC installation tricky, but the multi-position air handler solved everything—it mounted horizontally without issues. The compatibility with RS485/24V communication allows us to integrate it with our smart thermostat for remote monitoring. The variable speed compressor avoids sudden temperature swings, and the Energy Star certification ensures efficiency. Only reason for 4 stars: the communication module isn’t included, so factor that into your budget. Still, an outstanding system!
