Client Testimonials

I’ve been an Industrial and Residential customer of Primary Mechanical for over 25 years. I’ve tried others in that time but keep going back to Primary because they are good, reliable, efficient, and don’t cause me problems.
Dallas Van Kempen, EQyss Grooming Products

After having worked with Rob at PM for the last 14 years, he and his crew at Primary Mechanical have proven to be reliable at maintaining the rooftop units on the two-story building which I manage on site. I define reliable as getting a call back from him during the hottest days when he barely has time to wipe the sweat from his brow and making time to get me up and running as quickly as possible. After all, I understand I am not his only client and don’t expect same day service, although he happened to be in my area and I got same day. I hope his business prospers and he continues to be around for decades to come since good reliable help is hard to find these days. I have dealt with other companies, non-HVAC, that offer lifetime warranties, only to return later to the same address, same crew, service, but different business name, and hearing my warranty is no longer valid… delivered with a smile. I do not expect this with PM since their motto is ‘not to build sales, but to build relationships’ with their customers.

Pacific Coast Grill has used Primary Mechanical, Inc. for our heating ventilation and air conditioning contractor services for more than two decades, it is a great honor to work with a company that cares about their customers. They are very responsible and dependable for all the projects that we have carried out in our restaurant for many years.
The very knowledgeable, punctual, flexibility, professionalism and the great customer service that they provide us is something very special and we appreciate every thing they do for us! One of the most important things we truly appreciate is that Rob Faye is extremely comfortable to speak with and I appreciated his suggestions to get my systems back up running smoothly every time we have a problem! If I could do 10 stars, I would! These guys are awesome! Again, this company does not fall short with their customer service and hiring quality people who display honesty, kindness and overall integrity. Thank you!
