I had a very nice experience with Opie's One Hour Heating and Air. They came to the home and they put in a filter for the humidifier. That was my first time using them and I was quite happy that they were very respectful of the home. The staff was very friendly and professional. I appreciate that they were able to show up on time and how hard they worked during the process. The pricing was fair, as well, so I would absolutely recommend them to future customers. I am happy for the results that I received and everything is working well now, so you can't ask for more than that!
