Every time I call Dwyer for my AC, heating, water heater or plumbing needs, they are very courteous and professional; from the first phone call to the technician who arrives. Most recently, we turned on our AC to discover it was no longer working. I called at 7 am and they had someone there that day and they had all the necessary parts and tools with them to fix it immediately. Every one that works there is very dear and we would never call anyone else!
