  • Extremely satisfied with our AC and combi boiler installation — the team was professional from start to finish and handled every roadblock that came up along the way without missing a beat. Highly recommend.

    Ernesto B.

  • ⭐⭐⭐⭐⭐ 5-Star Review for Naveed I highly recommend Naveed and would confidently give him a 5-star review. Naveed not only successfully replaced my AC system, but took the time to perform a thorough assessment of my condo in Oakville and identified that the original system was undersized for the space. Instead of simply replacing equipment, he recommended and implemented a higher-capacity solution that better matches the cooling requirements of the unit. His attention to detail, technical knowledge, and willingness to explain the options gave me confidence that the right long-term decision was being made. What impressed me most was that he approached the project as a complete solution rather than a simple equipment swap. He carefully evaluated the existing setup, answered all my questions, and provided practical recommendations based on performance, reliability, and future needs. The best endorsement I can give is that after completing the AC upgrade, I am now asking Naveed to replace my Combi Boiler as well, which is a much more specialized piece of equipment. That level of trust speaks for itself. Naveed is professional, knowledgeable, reliable, and genuinely focused on doing the job properly. I would not hesitate to recommend him to family, friends, or anyone looking for HVAC work done right. 5 stars, highly recommended. ⭐⭐⭐⭐⭐ Ricardo Boscan Oakville, Ontario

  • Naveed literally saved us during the heat wave! My AC stopped operating and the house got dangerously hot…Naveed came the very next day, assessed the situation and did a small temporary repair to get me through the heat wave until he could return a few days later with a new coil. It was fast, efficient and affordable. He talked me through the process, explained the system to me; what was needed and helped me feel heard and safe. Highly recommend!

    Andy S.

  • I’m very satisfied with the service from A to Z. They installed a brand-new Carrier furnace and AC system for a very fair and reasonable price, and the whole job was done well from start to finish. I could tell they know what they’re doing and don’t cut corners. They replaced the AC copper lines with brand-new lines and installed them very neatly. They also rerouted the PVC vent pipes cleanly, made sure they were properly sloped, and ran the drain lines toward the floor drain where everything was secured properly. For the furnace, connected the gas lines and made sure they were safe. They also sealed the ductwork seams with proper HVAC-rated tape and made sure the whole system was running smoothly before they left. Another thing I appreciated was that they guaranteed the disposal of the old equipment, so we didn’t have to worry about that afterward. Overall, this was honest, professional, high-quality work at a great price. I would definitely recommend them and would use them again for any future HVAC work.

    Abdul X.

  • I had an excellent experience with air conditioning technician Naveed. He was professional, knowledgeable, and very punctual. He quickly diagnosed the issue and fixed it efficiently while explaining everything clearly. His workmanship was clean and thorough, and he made sure the system was running perfectly before leaving. It’s hard to find technicians who are both skilled and honest, and Naveed truly exceeded my expectations. I highly recommend him to anyone looking for reliable and professional AC service. Thank you again for the outstanding work!
