    Repair or maintain airconditioning-
    I was not impressed. The tech couldn't do basic tests on the AC, like refrigerant pressure, said he didn't have the tools. Was kind of dismissive and told me I needed a new capacitor. Replaced it but then the "control board shorted out". Said wasn't his fault, blamed it on the age of the equipment. Left and told me someone would call me the next day to discuss. I did get a call, from their AR asking for payment. They had no idea there was a problem. Thankfully I have a maintenance agreement with Reliance Home Comfort and they came in to replace the control board. Their tech was professional and detailed. Explained to me what could have happened and replaced the board. All Knight did was call for money. Jeff at Knight should really try to keep better notes. Knight's "Cooling Diagnostic" report, for which I paid $169 for was rather "skimpy" on the details. Will use another contractor in the future.

    Repair or maintain boiler-
    Boiler system was red-tagged by Enercare. Enercare were unable to assist with addressing the problem they had caused (strange and definitely not what their advertising says). Tenants were cold. Marnie and her people at Convertible did a great job getting people on-site right away, removing the old boiler, and getting a new combo boiler/hotwater tank system installed so that the heat and hot water were restored and the tenants able to live comfortably again. I would highly recommend Convertible (and would 100% not recommend Enercare !)

    What a wonderful experience we had with John and his team. Vito, Jeff, and Oaklan were true professionals and made our home whole again. After suffering a flood in early July we contacted the team through homestars and we couldn't have asked for a better, more professional crew. Their attention to detail and willingness to go the extra mile made for a relatively quick and seamless operation. Without John's great advice on how to approach our insurance claim we would have suffered greatly. We will be reconnecting with Oborne Contracting for any further work on our home!! Thanks again for all your hard work!

    Install or replace airconditioning-
    High Efficiency was very responsive to my questions and gave me a very detailed and competitive quote. They are a Carrier dealer and Carrier is the brand I preferred. Other installers seemed to be more ready to put in whatever they had in the shop and were not as familiar with their product as High Efficiency. They arrived on time, did the job neatly and quickly and even registered my warranty for me.

    We recently hired Haus Construction Group to renovate the kitchen and bathroom in our condo unit, and we are extremely pleased with the results. The entire process was smooth and efficient, and the quality of work was exceptional. The Kitchen designer (Andre) did an outstanding job with the kitchen renovation. From the initial design phase to the final installation, their attention to detail was evident. The new layout and the quality of the materials used exceeded our expectations. The bathroom renovation was also a great success. The team demonstrated attention to space utilization and the overall aesthetic of the bathroom were impressive. Throughout the project, Mark and his team maintained communication. They were always responsive to our questions and concerns, which made the entire process stress-free. Mark was particularly aware of the condo building regulations, which ensured a seamless renovation process without any issues with the building management. The team's professionalism and respect for our property were noteworthy. They completed the project within the agreed-upon timeline and budget, and any minor issues that arose were promptly addressed. In conclusion, we are highly satisfied with the work done by Haus Construction Group. We would not hesitate to recommend them to others looking for a reliable and skilled contractor for condo renovations.

    Put up lighting-
    Mike did an outstanding job replacing my ugly dome lights in the basement and some other areas with sleek recessed gimbal lighting and now they light it up so evenly and has elevated the look of our home. He even helped me out a lot by installing a switch, an extra light and removing some light fixtures for which he didn’t charge me. Very honest and with great pricing as well, I’m super happy I made the right choice hiring Gargano Electric 😊

    I had the pleasure of working with Jonathan and Jason to restore my client's unit after it was left in terrible condition by a previous tenant. The tenant had caused significant damage, including broken doors, a damaged sliding door, and extensive harm to the bathroom, along with scuff marks and wall damage throughout the unit. Jonathan and Jason were incredibly efficient and professional in addressing all the issues. They replaced the doors, repaired the sliding door, repainted the entire space, and performed thorough patchwork on the walls. Their communication was excellent throughout the entire processalways clear, upfront, and timely. They kept me informed of the progress and were transparent about the costs, which I really appreciated. The quality of their work was outstanding, and they completed everything on schedule. Im very impressed with their professionalism and craftsmanship, and I highly recommend them to anyone looking for reliable, skilled professionals!
