Moore & Russell Heating Ltd

We recently replaced our furnace and added an AC unit from Moore and Russell. There were multiple issues early on that included them bringing a furnace that didnt fit in our furnace room on install day. Then not returning our calls and lots of broken promises before finding a unit that would fit. Finally we had our furnace and AC unit installed. The AC unit barely cools our house at all. I placed multiple calls into Moore and Russell and didnt receive calls back. Finally I placed a Google review stating the facts and they called me to ask about my bad review and sent someone out to the house to look at the AC unit. They said that the information the sales rep gave us was incorrect but that they could do an adjustment that would help, it did not. Our AC unit still doesnt cool our house at all.
They supposedly sized our house and did heat loss calculations and assured us the AC unit would cool our house but it doesnt. The AC will not cool our house below 24 degrees.
I feel taken advantage of and feel like that they just said what they had to to get the sale. Finally after multiple visits from Moore and Russell repair people they have acknowledged that there was an issue with the unit and replaced it under warranty. Although they are still stating that it wont cool to the levels I was promised by the sale person. The manager said we should have known it wasnt possible to cool to the level the Moore and Russell salesman said would. We are not experts in this field and trusted the experts at Moore and Russell.
My advice is if you are going to use this company, do your own research and/or get a second opinion because they dont stand behind what their sales people promise. We got rid of our portable window air conditioners because they said the measurements of our ducts and the unit would cool our entire house. But it does not.
