I noticed on Friday evening July 3rd that my HVAC system stopped blowing air throughout my house. I called Allgeier air the next morning to have a service technician come out to my house to look at my system. The owner of the company, Mr. Allgeier was the one who came out and he spent quite a bit of time testing things and running a thorough diagnostic. He told me what was wrong with my system as well as what to do if it messed up prior to them coming back to fix things. They called me Monday July 6th to tell me when they would be out to fix things. They came out that Wednesday to start on the job and were supposed to finish it on Friday July 10th. However I received a call on Friday letting me know the part didn't make it in but that they would be out to my house on Monday July 13th. I started having issues again with my system this past weekend and was very pleasantly surprised when I came home from work today (Monday July 13th) and not only was my HVAC system blowing, but it was blowing cold air. I can not sing their praises enough. This is the second time I have used them and I will make sure I tell everyone I know about my experience and refer everyone who asks me to them for service. They are top notch in my book and the deserve all the thanks in the world.
