"We could not be happier about the decision we made to contract Northstar Plumbing, Heating, and AC to replace our old AC and furnace. When Tommy arrived at our home, he was extremely polite and professional. He invited us to accompany him on his inspection and he explained his diagnostic readings and results in easy layman terms and presented several options for us to consider in the end. He walked us through the different options with clarity and product knowledge allowing us to make the decision that we are now extremely happy with. Our install happened the following day and the 2 technicians ( Joe and Joseph) that came out were well groomed, polite, knowledgeable, and and also allowed us to accompany them through the entire install explaining and answering all of our questions along the way. Their cleanup at the conclusion of the process was impeccable and we would highly recommend Northstar for all AC and heating needs. We have already recommended them to our neighbors that are having issues with their aging AC."
