Several months ago we learned all duct work under the house had to be replaced. The company that…read morehad maintained our HVAC for years refused to even give us a quote saying the crawl space was too small. I called another well known company in the area and they also said no. I found the Nerds. They came out, said it could be done. They replaced all the duct work. I can't say enough about their skills and professionalism. They warned our HVAC unit was old and probably going to need to be replaced. Well on July 2nd 2026 during a heatwave the system died. We reached out again to the Nerds. They replaced our system with a larger one because the old one was too small for the house. They once again displayed their skills and professional behavior. Their Customer Service is excellent. They are family owned and operated and many of the staff are Veterans. We trust them completely you can too.

For a day with temps in the upper 90s and with classes beginning the next day that was a phenomenal answer! Mike Lamb came at the appointed time, sent photos, gave me a detailed explanation over the phone and went right to work getting our tenants taken care of.
