Check licensing and insurance
Before hiring any hvac company, confirm they hold the appropriate Suffolk County license for their trade and carry liability insurance. It is reasonable to ask for both before work begins.

Confirm permit requirements for your specific project with the Town of Smithtown Building Department before major work begins. A reputable local hvac company handles permitting routinely.
