Noticed a ceiling stain in my foyer, just below the attic air handler. After pumping water from the secondary drain pan, I called National Refrigeration. They sent Ryan H. out the same day. Since we built the home in 1998, I've not encountered someone as knowledgeable about AC systems as Ryan. Before doing anything, he first asked for a description of the failure symptoms (AC coolant was recently charged by another company about 1½ months prior, after evaporator coil had frozen and then thawed). He systematically checked the attic air handler, disassembling enough to diagnose that the primary evaporator drain, once cleared, was functioning properly. Next, he moved on to the outside compressor, where he determined the fan was blowing but the compressor wasn't operating. He diagnosed that a failed relay was the root cause, replaced it, and the compressor operated properly. He then monitored the coolant level, and determined that the system coolant was low and required a charge. At each step he took adequate time to inquire about how much coolant was added from the previous service. Rather than speculate as to what caused the failure, he spent the time necessary to evaluate possible failure scenarios before offering solutions. Unlike previous service, he didn't sacrifice work quality to rush to the next call. And he went back upstairs to verify that the AC system was running adequately on a hot summer day before leaving. I look forward to a proposal for options that provide a more permanent fix.

Sam came to fix a recurring issue we've had for the last 4 years with our AC unit. We've had many different companies in to fix it - but never a permanent fix. Sam did a thorough review / repair of our system, but more importantly, he took the time to educate me on the issue and changes we could make in how we use our system, so that we never have this issue again.

First time with National Refrigeration, new HVAC system was installed and I had them come out for an annual service. Jarrod the tech was here for awhile doing what they do. Very professional, I had an issues which was above and beyond regarding the fans constantly running. He spoke with the manufacture and solved the problem in 15 minutes. The company that installed the HVAC system was of no help to me. I was very pleased with the service.

Hi, today we had Samuel Gil from National Refrigeration visit our home to service our HVAC system. Samuel was very polite and courteous and got right to work. We had several questions and concerns to ask regarding the system and Samuel checked out each concern and answered each question with detailed explanations. Samuel was neat as he came in and out of our condo. Samuel replace the evacuation pump on our HVAV system efficiently and thoroughly tested it for proper operation. We thanked Samuel very much for his service and thank you National Refrigeration for having such experienced and efficient service staff. Also, we want to commend National Refrigeration for their customer service, who took our request for service and helped us schedule a date that worked for us. Also, their followup calls to remind us of our service date and time were very helpful. National Refrigeration, A great organization.

Ryan came to our home to fix an air conditioning system. He was professional and was able to diagnose the problem in a timely manner - he is an experienced HVAC guy. He was friendly and respectful. Ryan ordered the part and came back to fix the problem about two weeks later and everything is working fine now. Thanks Ryan, L Choinski North Kingstown, RI
