Best Heating & Air Conditioning / HVAC In South Lyon

“From start to finish, the experience with Heinanen Engineering was incredibly professional. Unlike other companies, they didn't take a 'one size fits all' approach; they actually performed a full load calculation to ensure our new system was perfectly sized to prevent frequent cycling and excessive wear. The attention to detail was impressive—they even custom-made the ductwork to ensure proper airflow. The technicians were clearly experts, highly knowledgeable about the systems, and very respectful while working inside our home. I really appreciated the zero-pressure sales environment. They provided facts and details on how the system would perform rather than a sales pitch, and I was kept updated throughout the entire installation process. Our home is now perfectly comfortable and stable in every single room. After finishing, they did a complete walkthrough to explain how everything works in detail. I would highly recommend HEI!“

“We used a different company who had come to our house twice, a week apart and when our air went out a 3rd time they told use they couldn't come out for almost 2 weeks. We called Hauser and Mike had someone at our house with in an hour. Found the problem (That should have been caught by the other company) got us up and running quickly. The technician was very friendly and knowledgeable. He took the time to show us the bad part and explained everything to us. He stuck around after the air was running to continue checking pressures and levels to make sure that it would continue running. He was very professional, we made sure to even have him put a sticker on our furnace as going forward we will be using Hauser for all of our heating and cooling needs. Hopefully we wont need to call them anytime soon, although I know that if we do, they will be there and take care of us right away. When the owner takes the time to call you the next day and go the extra step to make sure everything is still running good and reassure you that they will take care of you, you cannot get better customer service than that! Thanks Hauser heating and cooling for everything!“
