  • Blue Sky HVAC

    New on HomeStars

    HVAC contractor in Alliston

    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

    This job required a full demolition and installation of a walk in bathtub, a new window, wall and ceiling tile, repairs and refreshment to the remaining drywall area and installation of a pocket door. The job required the involvement of several tradesmen. All of the guys were great. They obviously knew what they were doing, worked quickly with minimal intrusion on us. they were friendly and willing to answer any questions or concerns. they made a minimum of dirt and dust and cleaned up very well every day. the job was completed on time and on budget and we love it.

    Install or repair acoustic ceiling tiles-
    Scott was extremely prompt and finished the job for me on super late/early weekend hours (after hours as therapists) only 3 days after I contacted him. He was quiet, clean, and asked me for input along the way to make sure I was satisfied. He put up soundproofing panels for me in 4 different rooms.

    The experience we had was absolutely terrible! We DO NOT recommend this company. We've spent over $50,000 and still have an incomplete kitchen. We told Dan at Caledon Renovations, from the very beginning, that we needed the renovation completed as quickly as possible to sell and relocate for work. Dan told us that he could complete the work in 4 weeks. On June 3rd, 2024, demolition began on our whole main floor. Once demolition was complete, no one showed up for 2 weeks. We were constantly told there were issues sourcing product, finally, when he showed up with the floor tile, it was not what we had picked but decided to continue anyway to speed up the renovation. It is now August 7th and it still not done. There were several quality issues that were addressed several times and Dan offered to come back to fix these issues for a 3rd time - we declined. The final straw was when we had a subcontractor show up at our house demanding money or he would place a lean on our house. After speaking to this gentleman, we found out that Dan had not paid him and said it was because we owed money - we were paid up to date. When we told Dan we do not want to work with him because of the trouble he has caused, he offered a refund of $1200 for upper kitchen cabinet doors. Even though we were not satisfied with the refund amount, we agreed. We told him to pick up his sign from our home and give us the refund. That was 6 days ago and we've heard nothing from him. We now have to hire another contractor to finish the renovation which is going to cost us more money and time.
