From the very beginning, everything was handled professionally and with great care. Ehsan was punctual, courteous, and clearly very experienced. He explained the installation process, answered all my questions, and made sure everything was done to the highest standard. The work was clean, efficient, and completed right on schedule. The new system is running perfectly, and I truly appreciate the time Ehsan took to show me how to use and maintain it properly. It's clear he takes pride in his work, and it shows in the results.

We had an excellent experience with Markham Mechanical when they installed a new AC system in our home. From start to finish, their service was top-notch. Even on short notice, they were prompt, professional, and incredibly efficient. The Tech took the time to assess our home properly and recommended the most suitable and energy-efficient unit. He was very knowledgeable, courteous, and clearly skilled at what he does. The installation was done with great attention to detail, and everything was clean and organized when they finished. We really appreciated the transparency in pricing—no hidden fees or surprises. The tech also walked us through on how to use and maintain the system, and made sure everything was working perfectly before leaving. The whole process was smooth, stress-free, and handled with a high level of professionalism. If you’re looking for a reliable, honest, and high-quality HVAC company, I’d highly recommend Markham Mechanical without hesitation.
