Thank goodness for Wighton's! I made a mistake and called Jerry's Plumbing & Heating out to fix my heater and it did not go well (not even after TWO visits). My heater was still blowing cold air or no air and it was freezing in our house.  I called Wighton's and ...

These guys saved the day once again! Temp over 90 and our old AC goes out. I've used Wighton's since we moved in 12 years ago. Kept our older system running for years past when I thought it would go. Highly recommended!

Client Testimonials

"The details matter, engineering matters. Wighton's used their deep system design know-how to map out our office's legacy system, pinpointing where it was bottlenecked & underperforming. Their ductwork is a work of art. I really appreciate all the little details they baked in to make operations & maintenance cheaper in the long run. They don't cut corners. The feel in our office space has improved dramatically. The air feels better, smells fresh, tastes clean & our electric bill went down too! We look forward to our next project with them." –Peter K. Kardel

"Your installation personnel were very courteous and easy to work with, not to mention trustworthy. I can say that our experience with Wightons was extremely favorable and I was impressed with the detail of their quotes and the choices I could make to provide what we were after. Not to mention that Wightons was the only local firm that seemed capable of handling our needs which were not simple since they concerned existing homes that needed complete changes in the HVAC systems." –Anthony Detweiler

"He was professional and never pushy. Lenny was excellent! A pro at his job and a great guy! " -Lisa & Lenny Roberts Atascadero, CA

"It is a great company. They gave great customer service. They are very professional, very clean. I can't say enough about them. It was money well spent." -Patrick Wells Nipomo, CA

"Excellent, very professional, I would highly recommend and I'll use them again when I need a new hot water heater." -Chris Henry Pismo Beach, CA
