We had J & k install mini splits in August of 2025 and were so happy with the equipment and service that we called them back again in September of 2026 to install a new furnace and central air. Chris, Justin, Andrew and Jordan once again was amazing. Andrew and Jordan explained everything along the way and answered all of our questions. We couldn't be happier with their professionalism and work ethic. As with any project there are always a few hiccups but they handled it with ease and still got the job done in a timely manner. They were very kind and showed us alot of dignity and respect. Top notch company all around !!

​5/5 Stars – Outstanding HVAC Service and Top-Tier Professionalism! ​I am highly satisfied with the recent installation performed by J&K Mechanical. They installed a heat pump, furnace, ERV, and range hood at my home, and the entire team did a phenomenal job from start to finish. ​Justin came on-site to provide the quote and made the process effortless. His total package pricing was very competitive, and he set us up with a fantastic 5-year, 0% interest financing plan. ​Our installation technicians, Kevin and Andrew, were phenomenal. They worked on all four pieces of equipment over four days, showing immense dedication and attention to detail. Even though the job was originally expected to take three days, they never rushed—they prioritized doing a meticulous, high-quality job above all else. Throughout the project, they were friendly, polite, and always happy to answer my questions. On the final day, despite finishing a bit later than planned, they took extra time to thoroughly clean up their workspace. Their work ethic and professionalism are unmatched. ​To top it off, Kevin offered us an incredible promotional 1-year service plan after the installation. The plan normally costs $300, but because it included a 10% discount on the newly installed equipment, it saved us $600 overall—a complete no-brainer! ​I will definitely be using J&K Mechanical for future projects, including our upcoming water heater replacement. I strongly recommend them for any HVAC needs, especially Justin, Kevin, and Andrew!
