We had a new furnace and air conditioner installed on Feb 23/2018 the furnace was a York modulating 2 stage with a 1.5 ton York air conditioner, combined with the furnace it can achieve 18 seer, cause it is energy star rated, there are ample rebates from OPA and enbridge. My old furnace was a one stage about 19 years old and when it kicked in I had to turn my tv up or I couldn’t hear it. When my York kicks in I have to turn the tv down in order to hear the furnace, and trust me you cannot hear it, my refrigerator makes more noise. The furnace is designed to keep the house within a half a degree of your setting and so far I’m impressed. The over all comfort I am experiencing is second to none. The installers were well trained and did a very neat and tidy job, very professional. I would highly recommend this company and would highly recommend York modulating furnace and air conditioner. Warranty on these units is 10 years parts, I also paid an extra $650.00 plus tax to include labour for these 10 years. If you remove the extended labour of $650 and $4300 in rebates from the government my cost of $10,000 comes down to just over $5000 not including savings on my electric and gas bills. It’s only been a couple of days but so far very impressed.
