National is one of Rhode Island’s largest HVAC companies: Our success over 45 years means our company has the experience and resources to serve our customers in a timely and professional manner — even at times of the year (heat waves, cold snaps) when customer demand is high for our services. We are able to obtain equipment and parts from HVAC manufacturers at the lowest cost and quickest delivery — savings which we can pass on to you.
But National is also a family company: We’ve never lost the personal touch that dates back to our beginnings. We take pride in a company-wide concern for your family’s well-being — from our technicians working in your home to our 24-hour dispatchers, right up to the company president, Jack King. Our only goal is your 100% complete satisfaction with our services. We are all Rhode Islanders, and we love this region of close-knit communities.
