Nick from NK Heating and Cooling provided an excellent experience from start to finish with the installation of two Mitsubishi Electric mini-split systems in our home. One unit was installed in our master bedroom with a vaulted ceiling, and the other in our office, allowing us to efficiently cool these spaces without relying on the main house system—an approach that has already helped reduce our overall electricity usage while maintaining comfort. The quality of Nick’s work was outstanding. He took the time to clearly explain every step of the process, answered all questions thoroughly, and ensured we understood how to operate and maintain the systems. He also handled the warranty registration, which was a thoughtful and professional touch. Nick was punctual, accommodating, and very easy to work with throughout the entire project. His attention to detail and commitment to quality were evident in both the installation and overall service. I would highly recommend him to anyone looking for reliable, high-quality HVAC work.

Installed new thermostat and serviced the fuses to ensure the furnace works properly as well. Communicated the issue effectively and even went to retrieve needed parts to complete the job. Will certainly use this company for all my heating/cooling needs.
