We called Eric at Next Day air and heating and from the very beginning he was straight with us, accommodating and professional. He definitely knows the business and is current with which models to go with. He set up the install under the care of Aaron and Kai who did a fantastic job. It took 3 days and they were prompt, hard-working and patient with explaining the new thermostats. Also, respectful of our space and cleaned up at the end of each day. Highly recommend this company!
