“WE had a failure in our old heat system and we had a technician for fixing it. He restarted it but during the night it went down again (and it was the colder day in this winter). We then called AA-air who sent John. He noticed that the unit have had someone who used a spare part that wasn't the right one, so after he changed that we had our heat back and so far every thing is working!”
