Not worth one star. We have been a client for 5 years. They were our original installer/servicer. Pricey, but knowledgeable. Good history with us and a number of known neighbors and friends... until recently. THEY WILL NOT RESPOND TO EMAILS, CALLS OR DIRECT VISITS TO THEIR (INACTIVE) PLACE OF BUSINESS. They maintain an answering service, but NEVER respond. COVID can be tough on businesses, but no business should keep customers in the dark, as they are doing.
