We had our HVAC installed by Restano in 2008; all new ducts and appliances. Restano has serviced the system since then. When we've had an issue with the system, Restano was thorough in making sure we got the most out of our warranty, and then some. The company does regular servicing for an annual fee that is reasonable. As with any contractor, you need to ask questions about the work. But, overall, the workers and the work have been great.
