I had an issue with my air conditioning unit and the staff from Siemer Heating & Cooling was able to resolve the problem. They had to fix and replace some wires and I thought that they did an excellent job. It was my first time using them and I would consider using them again in the future. The only issue I had was that I didn't know that I had to pay a fee in advance - I thought that I would take care of the payment after the work was completed. But most importantly, they were able to fix my air conditioning unit and everything is working well for me now.
