"Marc called ahead and showed up on time. He was very knowledgeable about different options with the pros and cons well explained. Performed a through inspection of the duct system, took measurements for system sizing and made recommendations regarding cleaning, replacement, and material types. Very professional and I would use this company again."

"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"We would HIGHLY recommend Joseph from Canyon City Air if you are in need of a new HVAC system or in need of service! He and his crew performed excellent work. They were professional, friendly, detailed, knowledgeable, honest, and cleaned up everything thoroughly afterwards. He even contacted us a couple of days later to check in with us!"

"The service tech that came to our house, John, was very courteous, very knowledgeable and detected several issues that he explained in detail and it was easy to concur with his assessments. He found a big clog in a very old pipe, which had broken as he was inspecting it. This clog had been giving us problem and was preventing the air from turning on. He ran to home depot, bought a replacement part and installed it, at no additional charge! He also vacuumed the heating unit and installed a new latch to hold the filter in place. He took the time to explain about the need to ensure the filter is secure so dirt and dust does not work its way into the main unit (Which would be very bad!). He examined the outside air conditioner and we scheduled another appointment in 6 months for a nice general check up. The outside unit may have a leak, which we were previously aware of, but he provided us additional details and let us know what our future options may be. We decided in 6 months, when they return for the semi-annual service we signed up for, that we could see how everything is looking. Very happy with the experience with Magnolia!"

"The BEST phone call I have made this year for a service needed in my home was to Mirsky Heating and AIr. I called in the middle of a So. Cal heatwave because my thermostat had stopped working and I needed to replace it. How often does an AC company, in the middle of a heatwave, tell you they can come the same day? NEVER!! Except for Mirsky..Darrow told me that he would try to make it work..and he did...which I will be forever grateful!!! He checked in with me during the day to assure me that he was coming and not to leave work until he was more clear on the time he would be at my home. He showed up with another Mirsky employee named John..they were both super friendly and so helpful. Darrow found the problem and within 45 minutes, the thermostat was replaced and everything was up and running again. I can't say enough how grateful I am to Darrow and Mirsky Heating and Air...I am giving their contact info to all of my friends and will be calling them again for anything heating AC related."

"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."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"The service went very well. We had them replace the duct to suit our needs better. There were no additional fees for the service. The technician was proactive and I appreciated his feedback. Scheduling was very easy."

FAQs for swamp cooler service or repair projects in Diamond Bar, CA

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care.

Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.
