  • Cool air never felt so good!

    “I called late at night when I realized we had an issue and an actual person answered. He was able to fit me in for an early service visit the next day. Anthony was here the next morning right on time! He identified the issue quickly and was incredibly personable and knowledgeable. After he fixed it, the AC started working again right away! Cool air never felt so good. They sent many text updates pre and post the service visit which was also very convenient. Overall I would highly recommend them to anyone needing service for their heating/cooling systems. Best service experience I've had in awhile.”

  • I am very grateful for the excellent service we received!

    “With only a few days left before my pool is closed for the season, a wife who is an avid swimmer and a Hayward H400FDN pool heater showing code “IF”, I needed your help. Fortunately for me, Reliance Mechanical Services and Christian Castro were available to solve the problem, even on a Saturday. Christian showed up promptly at 8:15 AM this morning, assured me that he’d have the heater back in service in short order… and he did. Christian demonstrated a thorough knowledge of the equipment, impressive diagnostic skill and an extremely pleasant and cheerful manner even though he working in a chilly rain. The Hayward support technician I had spoke with accurately told me that your staff was well trained and knowledgeable. I am very grateful for the excellent service we received from Christian and your company.”

    “Doug was very professional, skilled, and knowledgeable. He diagnosed and repaired my issue in a very timely manner. He explained what the problem was and thoroughly checked out the A/C unit. I was very pleased with the service and repairs. I would highly recommend the company assuming that all of the technicians are as professional and qualified as Doug is.”
