Best HVAC company in the GTA Hands Down!!!

I learned about A1 from Yellow pages, and gave them a call. I have been looking to purchase a new air conditioner furnace for a few years now. The last few sales men I contacted were pushy and had many hidden costs...very sneaky. So finally I tried A1, The ladies at the office were extremely nice my salesman was fantastic and educated me on what I really needed. The installers were clean, quick, and informative. After they had a quality assurance inspector come out to make sure everything was installed properly and then made sure I understood my new thermostat...by the way wifi is the way to go !!! All in all it was a fantastic experience and I will definitely recommend them to anyone who mentions they need an HVAC company.
