I have been with Thermodynamix for three years now and have only positive things to say about them. Every tech that has come for either service or seasonal tune ups has been nothing less than polite, professional, knowledgeable.and patient in explaining things to us. The most recent tech was Eric Paolicelli who was all of the above! They are a reliable company who actually has HUMAN BEINGS answering the phone, not some AI computer menu. I highly recommend Thermodynamix to anyone in need of an AC or heating contractor.
