I just had my old furnace upgraded to a hi-efficiency model by Boonstra Heating. They also put in a new water heater. The installers Joe and Evan were very professional, looking after all the details and asking the right questions of me. The job was done within the time promised, they left the job site clean and tidy, and the new equipment is working great. I had a follow-up visit early the next day from Chris the service advisor, and he answered a few of my questions that I'd thought of since the job was done, and he gave me some very useful pointers about how to get the best use of our new equipment. I'm very, very pleased with the service I have had from these three Boonstra employees. This company makes extra effort to make sure the customer is happy.
