Hear From Our HappY Customers

    Fantastic service
    “Fantastic service, amazing attention to detail, very honest!”
    Wayne A.
    Extremely knowledgeable, professional and very honest!
    “I spoke to Edgar on Wednesday a.m. , explained we were told we needed a new HVAC system. I felt a second opinion was needed. Edgar scheduled to meet that afternoon. After checking the system, he immediately told us the furnace was very good and did not need replacing, he expected it would survive at least another 10 years. He explained a/c problems and they could be repaired with parts . Due to cost of replacement parts and age of unit, we felt it prudent to replace instead of repair. We discussed the brands we were interested in. Edgar had tremendous knowledge on each brand and was thorough in his explanation of each. He didn't try to rush us through our questions. Later that evening he sent quotes on the four we spoke about. The prices were very fair. His crews were booked through mid part of following week. During our initial conversation, I mentioned we had out of town guest coming for the weekend. He was concerned and said he would come by Friday evening or Saturday a.m. to add Freon to get us through the weekend. Thursday evening Edgar called to say he had our parts and he would install Friday morning! We were very happy and impressed that he was concerned for our comfort and weekend company. Edgar completed the job mid afternoon. He left the house immaculate and the house is cool again! He is truly a professional and a great guy. Very happy we found Edgar and we highly recommend Nu-Air!”

    A true professional in our industry.
    “A true professional in our industry. The representative is knowledgeable,informative, and a pleasure to do business with.”
    Mark
    Edgar is truly a dedicated and rare find.
    “Finally, after 4 years of dealing with incompetent air conditioner repairmen I have found a truly knowledgeable technician in Edgar Mejia, owner of Nu-Air Air Conditioning Repair.”
    George H.
    Stands out from the rest.
    “My AC went out on a Thursday night in the middle of the summer and after calling several HVAC companies who couldn't get to me until the following Monday, I called Nu-Air. Nu-Air arrived within a couple of hours and diagnosed my problem. Edgar walked me through my options and had estimates to me the same evening. Edgar located equipment at the distributor, picked it up, and worked late into the night to give my wife and I relief from the summer heat. I had my new AC system installed and the house cool before the other companies could even make it out to assess the situation. Nu-Air truly stands out in a world where customer service has mostly been lost.”
    Kevin
    Edgar is the kind of man that makes the world a better place. He made me a lifetime loyal customer in one visit.
    “As a single mom, one of my biggest worries is being taken advantage of when it comes to home repairs that I know NOTHING about. Edgar is possibly the most honest and knowledgeable professional I have ever met. He not only came the same day I contacted him, but he quickly diagnosed the problem with superior knowledge and skill, and assured me that I did not need a new AC unit when I was convinced I did (and ready to shell out thousands of dollars to replace the whole unit!). I won't even consider using anyone else in the future. The charge for his services were beyond reasonable -- and far less than I've ever been charged in the past. Edgar is the kind of man that makes the world a better place. He made me a lifetime loyal customer in one visit.”
    CMB
    Customer for life...thank you.
    “A friend recommended Edgar to me, couldn't do another year without air conditioning. He worked around my hours gave me different options. Very knowledgeable and professional explained everything to me. I decided to replace old system best decision I made!! I would highly recommend him to anyone if you want fast and wonderful service! Customer for life...thank you.”
    Dana H.
    Superior service!
    “I have an emergency outage. Edgar came right away. He diagnosed the problem and got us working in less than an hour, while testing the system to make sure there were no other issues. Excellent! Thanks again!”
    Mike
    Thank you Edgar!
    “He really took his time explaining all of its features and what to expect from him and his service team.”
