  • I'm very pleased with my experience with Climax. Reza helped walk me through different options to figure out what was best for me and did not try to upsell me. Installation was fast and professional. I highly recommend them if you're looking for an honest and reliable HVAC company.

  • Outstanding service from the Climax Heating & Air Conditioning downtown Toronto team. They responded incredibly quickly, visited my home within a day, and provided a comprehensive range of options without any pressure. Once I made my decision, they installed my new water heater, furnace, and air conditioner within just a couple of days. The installation team was professional, courteous, and did an excellent job, leaving everything spotless when they finished. I wouldn’t hesitate to recommend them.

  • Our air conditioner broke on the first day of a heat wave. Sam not only fixed our problem but took the time to walk us through how to prevent the problem in the future. We will definitely be calling Climax for our future maintenance needs.

    Neylan U.

  • had an issue with my furnace that I couldn't resolve and it got pretty stressful when it looked like it was out altogether. The tech was responsive, explained what it probably was, and was upfront about options and costs. He was able to stop by the same day and everything was handled professionally and as promised. Regardless of how things turn out long-term, I'm happy and feel they genuinely did all they could to help get me through it. I’d call them again.

    Mehdi B.

  • Fast and kind service!

    Tristan K.

  • Reza and his team were wonderful! Reza came to assess our Air Conditioning unit as it was not working properly, and we found out the compressor was broken. Unfortunately we had to get a new unit, but within 2 days we had our AC installed and working well! They were very informative to explain why the compressor broken, and what went wrong in the first installation to ensure this wouldn't happen again.

    Stephany K.

  • Sam was on time, thorough, professional, and gave us some some advice. We will definatly ask for him if we need our AC fixed again

    Geoff G.

  • Our AC stopped blowing cold air during a recent heat wave. Sam showed up quickly, diagnosed the issue, and had everything up and running in no time. Professional, friendly, and clearly skilled.

    Kathy M.

  • Sam was a lifesaver. Lost AC in the middle of the night in a heatwave. Called first thing in the morning. All other companies had days longs wait, Sam was here in the morning and AC up and running by noon. Totally recommend.

    Ern L.

  • Fantastic service - showed up earlier than predicted, fast diagnosis, fast repair. And this in the middle of a heatwave with 35 degree heat outside. Thank you!

    Danielle B.

  • Had a great experience with Sam. Climax was able to come the same day to change the capacitor on my central AC. The cost was was fair and almost half the price my normal HVAC contractor was quoting.
