We live by our tagline, Where Integrity Matters, placing what is best for the client at the forefront of how our company operates, earning us a stellar reputation. Our professional, courteous technicians deliver quality workmanship while also providing education about your system, any needed repairs, or the advantages of replacement.
We provide solutions using the HVAC brands and equipment we believe in most, but we are able to repair and maintain all brands.
The Evolution of MechaniCool
In 2014 our co-owner Robert, a lifelong entrepreneur, decided it was time to strike out on his own in the HVAC industry and time to quit “checking his integrity at the door”. With his wife Jamie (our Operations Manager) they began this journey by locking arms with other business owners, leveraging the reach of social media, and possessing the determination to always do the right thing.
In 2015 their son Nick completed his HVAC training and went to work for one of the largest contractors in Arizona, where he received amazing additional training and quickly became the guy they called when a diagnosis wasn’t easily found. As of 2021, the company runs 4 service trucks and all technicians work in every aspect of our services.
In 2022 we decided to take our company to new heights by adding plumbing services. Our new business partner Joel Weitz is a Master Plumber. He has been in the industry for over 10 years, working on projects both large and small. He has a background in restoration and HVAC, making him a perfect fit for MechaniCool! We continue to place our clients’ best interest as the reason of our decision-making and education, hoping to always be the company they turn to for their home comfort.
