Ray Delfera and his crew just installed a 12,000 BTU remote-controlled wall-mount Fujitsu Heat/AC unit in our greatroom and separate whole-house 2 1/2 ton heat/AC unit. Each job took half-a-day. His team, led by Rick, were punctual, …

Great company! My heater broke down earlier this year and they were out within the hour! Scheduling maintenance service is within a week or two, not months like other companies.

Great and fast service. They gave a possible quote on the phone while others only pushed a yearly membership for a very simple fix. Tech was professional and politely declined play doh from kids for payment. Will use them again.

Thank you Delfera & Co. for a j ob well done. We will recommend you to all our friends & neighbors!

Always a pleasure dealing with Ray and all of his employees.
