  • Blue Sky HVAC

    New on HomeStars

    With over 12 years of hands-on experience in the HVAC industry, I have worked for some of the biggest names in Canada, tackling everything from routine appliance servicing to complex incident investigations. I’ve been trained by old-school HVAC veterans who drilled into me one core principle: Do the job once, and do it right. That’s exactly what I bring to every customer interaction — a commitment to quality, safety, and professionalism. Whether it’s diagnosing a tricky issue, ensuring your system runs at peak performance, or making sure your home or business is safe and up to code, I bring real-world experience and a deep understanding of the trade to every call. When you hire me, you’re not just getting another technician — you’re getting someone who treats your home like their own, communicates clearly, shows up prepared, and gets it right the first time. No shortcuts. No guesswork. Just solid work backed by years of experience and pride in the craft
