Report
Can't say enough good things about RD Smith Heating & Air. I had a complete "tune up" of my AC last summer right before a heat wave, so when my house fan suddenly stopped working on a Saturday evening during the most recent heat wave, I was very bummed, and not hopeful for a quick response or fix. The first national company I called quoted an. INSANE price to potentially repair, and also said they likely couldn't the parts for weeks. Instead, by going with RD Smith, I got a get price, and a working AC by Monday evening. Very professional, very prompt, great responsiveness, even on Mother's Day week, and great value. Would highly recommend.

RAY, is the best! He's honest and does great work. He worked on our AC unit. And we recommended him to our friends. And they love him and his work. Truly a master professional in his profession.
