I have used All Heating & Cooling(Troy, MI) three times now. The first time I used them was 4 years ago after another company told me I needed a new furnace. I called All Heating & Cooling for a second quote as a point of reference. At that time a nice man came out and made a simple(and inexpensive) repair and best part — my furnace ran for another 4 years!!! I used them again this past summer when my air didn’t feel cool enough. A couple guys came out and very professionally told me that I needed to clean & maintain my outside unit, which was covered in debris. They give me some helpful tips and advise and I use the word professionally as they could have made me feel stupid but didn’t whatsoever! Saved me big bucks again. Naturally when my furnace just kicked the bucket there wasn’t another company that even came to mind. All Heating & Cooling came out and did an amazing job, once again. They were very reasonably priced, completed the job promptly and cleaned up after themselves. Very honest and reliable guys and now the only that I will use for all of my Heating & Cooling needs.
