Nick was great! He explained the issue and resolution clearly. He completed work quickly. He also went above and beyond and showed compassion for situation involving my elderly parents. I would highly recommend Nick. Our air conditioning is running well. Hopefully we won’t require HVAC service again, but if we do, Nick will be our 1st choice.

Recently, our 15+ year old A/C died and needed to be replaced immediately. From the initial consultation to the final installation, NK was professional, knowledgeable, and courteous. Installation was efficient and the old system was hauled away. The new system is up and running great! Highly recommend!

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.
