What Our Customers are Saying

This year when we were faced with replacing two heating and cooling units that were 25 years old, I was a basket case. A friend recommended Hamstra – and it was the best suggestion. Comfort Specialist Wes Adams came to the house, explained how the procedure would work, took measurements, and talked about the new equipment. My, things have come a long way making heating and cooling systems efficient, streamline, quiet and reasonably priced. The installers, Richard and James were very professional and well organized. The units look wonderful – the thermostats are easy to operate and now we can enjoy the house with cool comfort equally distributed throughout. I would gladly recommend Hamstra to anyone who needs to have heating and cooling work done. It’s great doing business with a locally owner company. Hamstra has made me a very satisfied customer.
