Renato provided very convenient service. He came on a Sunday morning and later installed on a Saturday because these days were best for me. (Most other companies only provide M-F for installation.) He arranged for a proper heat loss engineer to come on a Sat. also. The heat loss test showed an 80.000 btu furnace was needed (as Renato had suggested) Two other companies had said 60,000 btu's would be enough. I was so glad to get the more powerful furnace. He was the only person to suggest new wiring from the thermostat to the furnace, as the wiring was 40 to 60 years old. And this was done by an electrician that he arranged. Renato suggested a duct cleaning company that was good and reasonable, and they were. He was careful not to take any ceiling tiles down when running an electrical wire from the panel to the furnace. He also called and waited for Enbridge to come for immediate hookup on that same day even though it was 8pm by the time it was done. He is willing to apply for the O.P.A. rebate for me. (Some small negatives-he said he woud put a grill on the white exhaust pipe to stop small animals and didn't. One other firm suggested this but 2 others and Renato said its not needed. One of his crew broke one one of the two light switches for the basement when pressing down too hard. Renato is coming back in the spring to install the a/c and he said he would fix it then. I believe him and I'm ok with that as I can use the other switch beside it.) So all this work was done for approx $ 800.00 less than the cheapest company (and only a 60,000 btu furnace , no new wiring and no heat loss test) and approx $2,000.00 less than the most expensive quote, also without the 3 extras. (In case I can't enter it I would give a 9.8 out of 10 rating.) I would wholeheartedly recommend Renato. He really gives great service!. And his prices are top notch. Thank you so much Renato!.
