AR Air has been proudly serving our community since 1999, providing top-quality heating, cooling, and appliance services. We specialize in AC, heating, and water heater solutions, and we’re a Fujitsu Elite contractor for ductless systems. Our expertise also includes rooftop package units, PTAC units, humidifiers, and WiFi thermostats, along with repairs and maintenance on all refrigeration systems.

"Ralph looked over everything thoroughly and gave us an estimate. He came to do the repairs in less than a week. Ralph explained everything concisely and was happy to answer any questions. He is very knowledgeable, reliable, and careful. We have older units that were difficult to take apart and put back together; however, Ralph knew exactly what to do and handled the problem easily. He was very professional, careful of his surroundings, and cleaned up afterwards. He even helped us move some of the furniture back, which was unexpected and kind. Both my wife and I were impressed by his superior service. To top it off, Ralph is a great person! We are delighted with the wonderful job that he did. Highly recommend!"

Modern Home Improvement Services, Inc. is committed to excellence in every aspect of our business. We strive to exceed customers expectations on every project. .With over 15 years of experience in the HVAC and Home Remodeling business MHIS Inc is a company you can trust to get the job done right at a fair price. MHIS is your one stop shop for all your home repair and maintenance needs IMPORTANT INFO ABOUT R22 AC SYSTEMS!!!! MOST HVAC companies will tell you incorrect information, not on purpose, but because they may not be familiar with all the available options. If you currently have an R22 HVAC system, 9/10 contractors will tell you, you need to replace the whole system because R22 is being phased out in 2020. They are correct about R22 being phased out BUT what they are not telling you is your system CAN be CONVERTED to the new R410A Refrigerant opposed replacing your entire HVAC System. We offer New System Installation, And Existing Retrofits to help fit every budget

"From town permit application to installation and even cleaning up, the process went smoothly and 100% on schedule. They explained everything to us in detail and made us feel at ease. I can recommend their work to any friends!! Thanks Jimmy"
