Quality Reputation, efficient, reasonable price
February 12, 2026Lennox Company was founded in 1895. They have a long history of making a good, well built furnaces. I definitely trust the company for its long outstanding reputation. Just had a new Lennox Furnace put in my home and love the efficiency and quietness of it. Mine has a 10 yr warranty at no extra cost. We replaced our 30 yr old furnace.
Yes, I recommend this product.

Great efficiency, worth the price
February 11, 2026Our service company recommended this product when we decided to replace and upgrade our aging system before retirement. We are extremely thrilled with our purchase. This system is so efficient, we wish we’d installed this years ago! We feel it keeps the temperature in the home at the level we like without running continuously, and we never feel periods of too warm or too cool before it kicks in or off ! Love it.
Yes, I recommend this product.
