Mark Johnston –
I saw their winter ad and decided to give Jimmy HVAC a try. So glad I did — they installed the Lennox 90K furnace same day, and the price was exactly as promised. Excellent work, no surprises.
Jessica Brown –
Fast, friendly and professional. Jimmy HVAC installed my Lennox furnace the same day. The winter special was perfect for my budget. I’d definitely recommend them to anyone in the GTA.
Rachel P –
Installation by a certified Lennox dealer was smooth, and the unit runs silently in our open-plan living area. The performance in colder weather has been impressive warm rooms, happy family.
Robert Miller –
The team responded quickly when our old furnace failed. They brought the Lennox ML296 90 k BTU model, installed it the same day, and left the basement spotless. The performance is excellent — steady heat, quiet operation, and noticeable savings on gas. Truly great service!
Sarah –
From the first call to final testing, everything was handled professionally. The technician arrived promptly, replaced our old unit with the ML296 70 k BTU model, and walked us through all features. The warmth difference was instant. Great product and top-notch installation service.
Mark H –
In our coastal house the winters aren’t as brutal, but the 90k unit gives us plenty of head-room. It’s quiet, efficient and keeps the humidity/temperature stable. The only downside was a delayed parts order for the venting kit, which pushed the install date back.
Melissa D –
Installation went smoothly and the unit is very quiet. My only beef is that the thermostat we had didn’t immediately integrate, so had to upgrade that. But now it works well and our house stays cosy through early winter.
