We have been a loyal customer of Flanders Heating & Air Conditioning for over thirteen years now, and we trust them! We recently discovered that the pilot light on our boiler was dying, so we reached out. They came out, replaced the part, and did a fine job! The technicians were all very professional. They came in, did the job, answered all of our questions, and also followed the COVID-19 safety guidelines. Their customer service people, including the ones who answer the phones, are very polite and personable, and always provide a good experience, which is why we will continue to use them.
