There are two big concerns in living in the desert as a homeowner. Air conditioning and Termite protection.
Many years ago, I was fortunate enough to find Action Termite Control. They sent an inspector out to the house, gave me an accurate estimate, and treated my house with Termidor. Two years later, ALL my neighbors were infested with termites, but not my house! Our house remains termite free and I then recommended them to my infected neighbors who no longer have termites.

Termites is all they do, and they are true experts at it. Can't recommend them highly enough.
