"A big thank you to Jeremy Hesselink at Harmonic Heating & Air Conditioning for taking care of our furnace! He's knowledgeable, with many years of experience, punctual, and simply an all-around really super nice guy! He even helped Ally with an algebra problem. Totally recommend him! My basement is cleaner after he left than before he arrived. "
