 Trustindex verifies that the original source of the review is Google. Cliff’s did a yearly maintenance on my Generac automatic generator today.  They installed it in 2014 and it ran perfectly for eight days straight during the last power outage.  Tom Regalado took time to explain the maintenance he would perform and why it was necessary in order to keep the generator working flawlessly. I highly recommend Tom and Cliff’s

 Trustindex verifies that the original source of the review is Google. Cliff’s Heating has been the HVAC provider for my house and family for over 17 years. In all that time we have had outstanding service. The technicians they have sent to service out systems have all been highly trained, reliable, honest, and efficient. Last week Tom Regalado answered our latest service call and I did not think it could get any better. While I recommend Tom 100%, I also fear that by doing so, he will not be available when I need him. Like me, Tom believes in preventive maintenance. Ask for Tom when you call. There is no substitute.

 Trustindex verifies that the original source of the review is Google. While many of our neighbors had generators that didn’t start with recent power outages, Cliff’s maintenance kept our generator working and reliable. Tom recently performed outstanding service. We are so thankful we chose Cliff’s for our home generator installation and service.

From the office personnel, that actually answer the phone, to Tom, who provided great service on our generator and explained things my prior service company never mentioned in years of using them.  Very please to have found a company I can depend on for years to come.
