As a first-time home buyer, the process of purchasing a home and diving into renovations can be very stressful. However, my experience with First Key Homes for renovating my kitchen, bathroom, and flooring was truly outstanding. From the initial consultation to the final touches, Alain from First Key Homes was with me every step of the way! Their expertise and attention to detail were evident from the start, offering valuable insights and suggestions that aligned perfectly with my pinterest vision and budget. The renovation process can often be filled with unexpected challenges, but First Key Homes managed to navigate them seamlessly. Their professionalism and dedication to customer satisfaction that the project was completed on time and within the agreed budget. The transformation of my kitchen and bathroom is simply breathtaking, and the new flooring has completely refreshed the look and feel of my home. I couldn't be more pleased with my decision to work with them for my home renovations. Their service was truly amazing, and I have absolutely no regrets!

We had the pleasure of working with Ali and Armin for our home renovation, and they truly exceeded our expectations in every way. Their work was purely professional, of exceptional quality, and completed on timepossibly even a little earlier than expected. What made the experience even better was their incredible attitude. They were not only highly skilled but also genuinely wonderful people to work with. I added bits of work here and there during the project, and they took it on without any hesitation or discussion. They went above and beyond to accommodate my requests, including helping me by accepting appliance deliveries while I was awaysomething they did with kindness and understanding. Their calm and patient demeanor, combined with their ability to deliver outstanding results on time, made the entire process smooth and stress-free. I couldnt recommend Ali and Armin enough for anyone looking for reliable and personable contractors. Thank you both for your amazing work!

I recently had the pleasure of working with Consult Mechanical for the replacement of two furnaces and, later, a new air conditioner. From start to finish, the experience was exceptional. The quote provided was fair and competitive, and the team took the time to thoroughly explain all the available options, ensuring I could make an informed decision. They arrived promptly on the scheduled days and completed the installations efficiently. I was particularly impressed with their professionalism and attention to detail. The team left the work areas spotless, which was greatly appreciated. Throughout the process, their communication was prompt and clear, addressing any questions or concerns I had swiftly. They took the time to assess the electric filters as well as our humidifiers, and ensured everything was up and running like new. Overall, Consult Mechanical exceeded my expectations, and I would highly recommend them for any HVAC needs.

Tankless install went smoothly from start to finish. Eugene quoted me the best price (vs five other Best of 2026 award winners) and was able to turn the job around within 24hrs. His team completely delivered. They were punctual, professional, and able to solve the unique challenges to the job. Very satisfied overall. I would feel comfortable hiring this company again and will recommend them to others. Thank you to Eugene and the boys for making this process as painless as possible.

Latest review:
When our furnace started to malfunction, I called Edward, who was my furnace maintenance serviceman. Edward came by and gave our furnace a temporary fix. He pointed out that there was a leakage in the system, and the fix would likely not last. Seeing that our furnace was twenty years old, my wife and I decided it was time to replace the system, and since Edward had given us good reliable service in the past, we thought he would be the appropriate provider. Two days later, Edward arrived as scheduled with two other servicemen. They fully protected (the flooring of) the part of the house through which they had to move the equipment to get to the basement where the furnace is normally housed. They cleared an adequate area so that they could worked reasonably comfortably. For three to four hours, they worked furiously at dismantling the old furnace, and installing the new one. Throughout the process, they seemed to know exactly what to do. The only question they had was one concerning the exhaust pipe, as regulations have changed. In the end, they completed the installation, moved everything in the basement back in place, and did a general sweep up. Because the new furnace is a little smaller than the old one, the basement actually seems to have gained some space in the process. At the conclusion of the installation, Edward accompanied me to the site, explained the equipment to me. He also explained the invoice to me and answered my queries. This marks the second time I have dealt with Edward, first time being furnace maintenance last year. I always find him to be a very trustworthy person. He is quiet but he tells you everything you should know and need to know. He is a man of his words, and certainly very knowledgeable, and gets things done. Now I know he is also technically very competent, and can organize teams to get systems installed.
