JJ Douglas Services

Holly Hill's JJ Douglas Services covers heating and cooling across Volusia and Flagler counties, and it is a certified Trane dealer. It sells and services all major brands and offers air conditioning, heating, and maintenance programs. Its pool work centers on installing and servicing pool heaters, so pool resurfacing and other pool renovation work are not part of what it does. Most of the systems it installs include a 10 year parts warranty at no additional cost, provided the equipment is registered. Its certified technicians help customers choose the most efficient cooling and heating equipment for a home or office, and they repair and provide routine maintenance on the systems they service. The company is fully licensed and insured. Rated 4.9 from 50 Google reviews, 48 of them five stars.
