#QuickTip ⏳ If your air conditioning doesnt seem to be working properly, the first thing to do is check whether the drain is clear. Clogged drains can cause water build-up which causes your system to shut down. Unclogging the drain is an easy fix that can be done by any homeowner!

Once you have ruled out a clogged drain, contact Wightons Heating and Air Conditioning for an experts opinion on the condition of your unit.

#FunFact 💡 Because of the intense heat, people would gather in movie theaters to enjoy the cool air. This is actually how the term Summer Blockbuster was started.

Now I understand why movie theaters are always exceptionally cool!

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
