I've been using Air Tro for 30 years. Started with business in Pasadena where several heating and air units were installed. They use top quality equipment and continue to provide quarterly maintenance services as well.
We have always had great service from Air-Tro. When we have had to renew a part, it is always because that part is truly worn. Most years the cost is just the normal annual cost, which is very reasonable.
Andrew was very helpful, but my heater is still not working correctly. It wouldn't come on at all last week, when it was very cold (the default temp is 60 and the readout showed indoor temps in the 50s). It won't come on when I set it to higher than 60, but oddly enough, it was on when I got home l
It was painless and fast, and the guy was intelligent and courteous.
