DNA was very professional and worked hard until the job was finished. They replaced a 30 year air conditioning unit and gave us a very reasonable price with no hidden fees or costs. I would highly recommend them.

One of the few companies in Las Vegas to instal Humidifiers. I needed two since we have two heating units. Our newly installed wood flooring was drying out and shrinking. Funny, in such a dry area there are few homes with humidifiers. Two installed. They had some minor issues and made the adjustments over three days. I was very impressed with the young man who stayed until 8 PM to make sure everything was right. I will be using this company from now on. Even if you suffer from dry nose and skin, especially in winter the Aprilair Humidifiers are top of the line.

Andre did a wonderful job installing a Mitsubishi split system in my large garage space. They showed up with masks, did a very thorough job and cost significantly less than two other competitive quotes. I have an older Mitsubishi system in the house I purchased last year, and one of the units stopped working and shut the entire system down during the coldest time in Vegas. Andre came right out and fixed things so we had heat again. I highly recommend DNA air conditioning and Heating.
