Siemer Heating & Cooling is the only company I've ever used. For twenty-five years they've serviced my heating and cooling units. It's a real family company. When the time came to replace my entire system, I met with one of the Seimer sons, who went through all the options with me. Then, the father came out to take a look at things. The new units are top of the line and energy efficient. Through the entire process, they were solicitous towards my every need. They came out repeatedly to check on things and made sure everything was running smoothly. They called on the phone to check on things. They coordinated the new A/C pad with the workers for a patio that I'm redoing in my backyard. When I stop by the office for supplies like air filters, the office staff is knowledgeable and attentive. I highly recommend Siemer Heating & Cooling! They have taken excellent care of my needs for a quarter of a century!
