We've used Ongaro & Sons to install air conditioning, move a thermostat, and recently to consult about outdoor lighting. We've been very pleased with their services and have found all technicians to be competent and extremely pleasant.
My most recent interaction was with Mark (fabulous) who moved the thermostat, and Renee, who saved me money by suggesting they install new outdoor fixtures rather than add more outdoor lighting. -

Ongar & Sons has been instrumental in getting our AC unit fixed during when the weather was extremely hot. Great customer service the office was very helpful in getting someone to come out and ocenia the problem. I just signed up for their maintenance service for my HVAC system so that we can prevent any problems and address any issues before they become big issues.

I highly recommend Ongaro and Sons. After speaking with several plumbing companies about replacing a failed section of my home’s sewer system, Ongaro and Sons offered the best pricing and delivered outstanding service. Special thanks to Aldo and Amado for making the entire project seamless!
