    "Great Service!"
    Very professional and exceptional service. We had a total A/C failure and Lewis Air was quick to replace the old unit. Techs thorough and the work great value all around. The same team replaced the A/C unit at my daughter's home soon thereafter. Highly recommend their service!

    "Super personable and kind as well as being experts in the business."
    ONCE AGAIN, Lewis Air came through for us. Lewis Air has been helpful to us on more than one occasion with one being this week. Even though they were slammed during super hot days they gave us attention and helped us get our A/C going again! Super personable and kind as well as being experts in the business.

    "Lewis Air always does a good job and I'm glad I do business with them and bought a complete furnace and ac unit from them"
    Blake is a very nice young man. He was very knowledgeable and helped me out. He understood I was a disabled Marine and even set my attic exhaust fan temperature to help the ac unit and attic to be cooler. He found the problem I had with my unit immediately after other techs always thought they knew what was the problem. He even gave me a veteran discount on the labor. Lewis Air always does a good job and I'm glad I do business with them and bought a complete furnace and ac unit from them Michael Browne 6 Bootstrap Court Trabuco Canyon, CA 92679

    "Thanks Lewis Air for your excellent customer service."
    “My Lennox HVAC unit is covered by my home warranty company and I tried multiple times in getting a repair date of the unit. It was getting colder for the holidays, therefore I called Lewis Air (a local company) and spoke with their very emphatic and professional call center for an appointment. The next day Jeffrey came out, inspected the unit, installed the part and had the unit producing heat within 15 minutes. Thanks Lewis Air for your excellent customer service. Note: It’s week 4 and to date, I have not heard from the home warranty company or their HVAC vendor that should have made the repairs.”
