fourseasonsac.ca 5 Henry Franc @2015-07-10 Fantastic system, service and support! They helped me arrange for both vendor rebates and gas supplier rebates; coordinating with the energy auditor was also helpful. They had all the paperwork for me to submit for the rebates and warranties and helped set up the thermostat and the web interface. As for the install work it was clean, quick, very neat and the best part is they really cleaned up after themselves. The system is super efficient, easy to use, saved me a lot of money on energy ... and whisper quiet. The Lennox HE system is amazing ... I was working outside while they were doing the install and when they turned on the A/C I didn't even hear the fan unit and I was 10' away from it. I had to walk over to the unit and look at it because I didn't believe it when the tech told me it was running.
