Customer Reviews

What GTA Homeowners Say
About Their Lennox Furnace

5.0across Google & Facebook

The EL297 is the quietest furnace I’ve ever had. H&C recommended Elite because our furnace closet is right next to the master bedroom — great advice.

Installed in our new build. SilentComfort really works — you genuinely cannot hear it. Worth every penny over the Merit Series.

Robert K.
Aurora · Google Review

Paired with an iComfort thermostat — seamless integration. Monitor from my phone and the two-stage keeps the house perfectly even.

Third furnace H&C has installed for us. The EL297 is noticeably quieter than the ML296 in our rental. If silence matters, go Elite.

James C.
Thornhill · Google Review

Gas bills dropped about 15% compared to our old 90% furnace. The 97% AFUE is real — longer runs at low fire instead of blasting.
