"RKM made this almost a pleasure. We started with a service call to evaluate/fix the old A/C. Richard was on-time, skilled and helpful. RKM phoned to confirm appointments and sent email messages to keep us updated re: arrival times. When new equipment was needed - Robert helped us navigate the choices and design a system that was a more efficient Energy Star rated unit that met our needs at a price we could manage. We didn't need financing but, that was available as a reasonable option. Proposals, invoices and equipment brochures were all sent in detailed & easily understood email messages. Installation of the new system (furnace & A/C) went smoothly as scheduled. The installation team - Jonathan, Brian and Julio - were on-time, friendly and knowledgeable. They took care to protect our homes interior and yard. All of the old equipment was removed and new installed, tested, etc in one day. The new a/c compressor, made by Gorman is QUIET; It's only been 24 hours but, the house is COOL and we can't hear anything in the house or yard."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."
