When our AC went out, we literally had our previous, well-known service fail to return our calls three times. We tried Mel-O-Air and were knocked out by their quick response, friendly service and professionalism at every point of our Carrier installation. We are their new and future customers and they earned our business.

Highly recommend this Company for any heating and cooling needs. We moved into a new home and our 17 year old HVAC gave out very late on a Friday. One of the owners got back to me within minutes and was at our house by 7 am the next morning. We received a comprehensive list of options for a new furnace/AC and the team walked us through everything in detail. The crew installing everything was extremely friendly and the level of workmanship was impeccable. Once completed they showed us how to use everything. The office even handles the all the rebates so it is as easy as possible. Wish all home

I called Melo Air to have my AC condenser clean and the unit checked. At a minimum, I expected them to clean the inside of the condenser (vacuum, remove debris) and clean the coils with a cleaning solution. Those two things in themselves take less than 30-40 minutes. The technician came, checked our unit, advised we get a different air filter, but the AC unit was never cleaned. I was only around for the beginning of the appointment, so I was not able to inspect the work at the end. I came home later that day expecting to find a clean AC unit. Unfortunately, there was still all of the debris still

We have used Mel-O-Air over the years at several of my homes. They are always responsive, friendly and fair. Recently had them install a full A/C, heating and humidifier and couldn't be more pleased with the installation, professionalism and education on the new systems. We recommend them to anyone who is looking for maintenance or a new system.

Everyone at Mel-o-Air is well-versed in their products and heating and ac generally. They have been highly responsive to my questions and helped me learn about the various heating and ac options so I could select the best one for me at the right price. They very patiently explained how to use the internet thermostat. I love that they are a local business. Thoughtful and kind as well.
