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


"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


"He was professional and never pushy. Lenny was excellent! A pro at his job and a great guy! "-Lisa & Lenny Roberts Atascadero, CA"They performed the work to our satisfaction. They were responsive to our questions/concerns and were committed to "making it right". Companies can talk about excellent customer service but Wighton's puts it into practice." -Linda Coe Atascadero, CA


"They were excellent. They were always on time. They cleaned up everyday after themselves. They explain fully why they were doing whatever they were suggesting. They never tried to pressure me into more than what I absolutely needed. I went for the more expensive option because it was more convenient where we are located. The price was comparable to the work they did. I was extremely satisfied with their work." -Louisa Beeler San Luis Obispo, 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
