4 of 4 ReviewsThe Lennox Elite EL297UHV has been running smoothly since installation and has completely changed how our home feels in winter. The heat output is excellent, the airflow is consistent, and the unit is surprisingly quiet compared to our previous furnace. We especially appreciate the two-stage operation because the temperature stays steady without large swings. The build quality feels premium, and we are confident this furnace will provide reliable performance for many years. Very happy with our choice and would recommend it to homeowners seeking efficient, dependable heating.
After several winters dealing with uneven heating and rising energy costs, we decided it was time to replace our old furnace. Choosing the Lennox Elite EL297UHV 88,000 BTU 3 Ton was the right decision for our home. The biggest improvement we noticed was in comfort. Before, some rooms felt colder while others felt warmer, and we were constantly adjusting the thermostat. Since installing this furnace, the temperature has been much more evenly distributed throughout the house. The variable-speed blower provides smoother airflow than our previous system, and the difference is especially noticeable at night, when the furnace operates much more quietly. The two-stage heating is also a great feature because the furnace can run at a lower level most of the time, rather than using maximum power every time it starts. We chose this model because we wanted something efficient and dependable for Canadian winters. The 97% AFUE rating, ENERGY STAR certification, and Lennox reputation gave us confidence that this would be a long-term investment. After going through the heating season, we can honestly say this furnace has improved the comfort of our entire home. It feels warmer, quieter, and much more efficient than before.
Upgrading to the Lennox Elite EL297UHV 88,000 BTU furnace was one of the best decisions we made for our home. Our previous furnace was older and struggled to maintain a consistent temperature, especially on colder winter days. This Lennox model has made a considerable difference. The heating is much more even throughout the house, and the system runs much quieter than our old unit. We also like that it does not constantly turn on and off because the two-stage heating adjusts better to our home’s needs. The 97% AFUE efficiency was another important factor for us, and we are happy with how well it performs. Overall, it feels like a much more reliable and modern heating system.
With our old furnace, we were constantly adjusting the thermostat trying to find the right balance between comfort and energy efficiency. But our new furnace seems to have found the perfect balance on its own. Our energy bills have gone down, and our comfort level has gone up.
