Founded in 1947 as Rex Oil in Hartford, CT, our family business evolved into Grimaldi Oil—and now, three generations later, Grimaldi Heating & Cooling continues that legacy. Deeply rooted in the Hartford area, we’re dedicated to providing the same trusted, family-owned service and quality workmanship our customers have relied on for decades. We specialize in the installation, maintenance, and repair of heating and cooling systems, water heaters, and gas logs. With extensive experience in both residential and commercial HVAC services, we’re committed to delivering reliable, high-performance solutions that enhance your comfort and indoor air quality. What truly sets us apart is our unwavering focus on safety. As a former service technician for the local gas utility, I take every measure to ensure your home and equipment meet the highest safety standards—because your peace of mind is our top priority.
