A good company!
We have used Allied Services Inc for over 25 years. We built our house over 30 years ago, and we used a company previous to that. But that didn't work out, and we've been using Allied ever since!
They have re-installed many of our heat pumps, and a couple years ago they put a geothermal system in an area of our house. We use them for our yearly service upkeep. We continue to use them because they've always done a very good job, and we've had no reason to change.
They are very easy to work with, and they carry quality products. Their service is excellent!
