“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

What GREAT SERVICE on one of, if not, the hottest days ever in Paso Robles! Must have been at least 116 degrees! My poor 91-year-old mother was sweltering inside her home without air conditioning. It was 93 degrees inside, and we were having to wipe down my mother with wet wash rags to cool her off (as well as the caregiver and me, her daughter). The technician showed up within a couple hours and fixed my mom’s air conditioner within 20 minutes. We were so relieved! Wighton’s is always my go-to company when dealing with heating and air conditioning. They are reliable, knowledgable, and efficient. Thank you Wighton’s for saving the day!

As usual, a very positive experience. The young man who did the work today is a treasure. He was on time, did an additional task for me by cleaning a vent cover, and was so pleasant. He also seemed very knowledgeable about the system. He also took the time to make an appointment for me to get a bid on replacing my duct work I need that done soon!

Excellent customer service. I called regarding maintenance for my furnace, and the office staff helped me to determine which services made sense and which ones didn’t. On the day of the appointment, the dispatcher alerted me in advance that the technician was on his way, and he arrived on time. He was very professional and courteous. After performing the service, he explained exactly what he found and what choices I had in dealing with it. I thought the price of the service was quite reasonable. Overall, an excellent experience!

Mark did a thorough job and even took pictures to show me where my system may require further attention. He was careful to mask and distance for safety. He even moved a few heavy items for me🙂. I highly recommend Wightons!

My tech was super professional. Did a great job. Triple checked everything and made sure it was right. He wore a mask the entire time and was here exactly when they said he would

My toilet overflowed into the furnace duct. Wighton’s took the time to ensure I understood my options and proceeded a person to inspect the situation after hours at a nominal price. He was professional and reassuring.

Wighton’s responded immediately to our inquiry and sent their tech for our (non-urgent) AC service call the very next day. He was bang on time, professional and efficient, took the time to explain everything he was doing, and gave us some options with zero pressure, leaving us with a perfectly functional system. We would not hesitate to use them again

Reminder for 6-month checkup was timely and courteous. Also called on day of appointment to confirm and advise arrival time. Christian was punctual, polite, and thorough. Arrived with face mask (Covid-19) and shoe covers. He went over all the components inside and out testing, cleaning, and adjusting. Replaced air filter. Before leaving he gave us a thorough debriefing and answered all our questions. We couldn’t expect a better experience.

We’ve always had a good experience using Wighton’s Heating & Air Conditioning over the years. The representatives are always clean, courteous, prompt and efficient. They clean up after themselves which is a big help to me. They always call me ahead of time to give me a head’s up on their arrival time. I strongly recommend their service!
