We have been using Norris Air Inc. for our air conditioning maintenance for the past ten years. Since we're in Arizona, we LOVE our A/C, so we need maintenance guys who are reliable and reasonably priced. The time between when we call them to when the job is complete has never been more than a day. They give us a date and time and show up exactly on time. If possible, they will even move up the date for us, so we don't have to wait as long. They are wonderful. They are skilled workers, too. They know what they're doing and work as fast as they can with no problems. We've never had to call them back to fix a job. If you are considering Norris Air Inc, you cannot go wrong with them. Hire them already!
