Best Basic Plumbing in Mesa AZ

We have used this company for several years for our yearly maintenance of our AC unit. We were in Hawaii this year and the AC quit. Called them and they came out and informed us what we needed done. We had the work done called them the very next day and paid the $2000.00 plus and still received a letter that they were going to put a lean on our home if we didn’t pay. I don’t know what happened but sure am disappointed in them. Think it’s time to call the hall and get a new company.
