Save money by strategically placing your air conditioner that is away from direct sun. Having your system in direct sunlight means your AC has to work harder which uses more energy to provide the cooling you need.

Choosing a location wisely will increase the efficiency of your system along with your savings!

Customers Love Wighton’s.

    5 star review  My home air conditioner stopped working. I called around 8am and they had a technician out by 10am. I'm super pleased with the fast response. Mark inspected the unit and also up in our attic and diagnosed the problem. He then gave me an estimate and then fixed the problem. He was friendly, efficient, clear and straightforward. He was very easy to work with. I highly recommend him. Excellent customer service.

    thumb Amy F

    5 star review  I was incredibly pleased with the service. I called them on a Sunday during a heat wave and they immediately responded to get us cooled down again. Polite, professional and expert! I ended up signing up for an annual service because I liked them so much!

    thumb Dorothy Attwood

    5 star review  Cannot believe they got a tech out to me same day. Amazing. Mark was professional and knowledgeable. Helped me select the perfect thermostat. Was accommodating of the fact that my disabled husband is sensitive to sound. Left the area of the install cleaner than it started. Highly recommend.

    thumb Andrea Bradford

    5 star review  The service was great. Jesse answered all my questions. I could not of asked for a better serviceman. He represents professionalism.

MORE 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


“I just had an AC installed by Wighton’s and they were running a promotion to receive the vacation voucher based on the price of our unit. I was given the choice between the cruise or the condo voucher, we decided to go with the condo because we like land based vacations. We decided not to price hunt with other companies because Wighton’s is really popular in our area, so we know they have good reviews, customer service and quality products. Receiving the vacation voucher was the cherry on top of working with them.” – John Silacci


“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
