“Sal was very helpful and candid about my maintenance needs.”
Sal was very helpful and candid about my maintenance needs. He was willing to stay a bit late just to accommodate a situation that was beyond our control. I’d be happy to work with him again and I am happy to recommend him to others.

“Jorge and his apprentice provided outstanding service.”
Jorge and his apprentice provided outstanding service! They helped us replace a faulty toilet seal and clear a stubborn clog in our kitchen sink. They arrived on time, were professional, friendly, and took the time to explain what they were doing throughout the process. They worked efficiently, cleaned up after themselves, and made sure everything was working perfectly before they left.

Jay was great. He was on time and checked everything before finding the issue, he then checked the thermostat before leaving. He told us he would be ordering a part, and return soon. Very professional. Today 8/5 Mike Croff and his associates installed a new air conditioner. They arrived earlier than expected so we got them in and they went right to work. They worked for eight hours and we are happy and comfortably relaxing<br><br>Thank You!

“Wanted a review, evaluation and maintenance of our air conditioning system.”
Wanted a review, evaluation and maintenance of our air conditioning system. Deljo technician Gregory was exceptional in his service, taking apart the compressor, checking the thermostat, the return and delivery vents and everything in between, explaining how it all works. The system has emitted a low grumbling noise recently and Gregory explained how the ball bearings in the motor are wearing down, with an estimate of the cost to replace the motor.
