I have used Siemer Heating & Cooling for both my residence and my commercial office. I cannot say enough about them and would definitely recommend using them. My most recent work done by them was out at my home where I have a boiler in my garage. The thermostat was failing. When I called, as usual, they came out instantly and took care of everything. The technician repaired the thermostat and now it works like a million bucks! I like being able to use a local business as they are right in the neighborhood. The staff at Siemer Heating & Cooling really goes out of their way to give good service and assist their customers.
