Who We Are

Since 2004, Castlebee Refrigeration has earned a trusted reputation for delivering consistently high-quality and honest service at a fair, transparent price. As a homegrown and family-operated company, we’ve built our business on a foundation of core values—professionalism, respect, and integrity—and we ensure these principles are reflected in every interaction, from the first phone call to the final walkthrough.

We are proud to be a Mass Save®-certified contractor and a Mitsubishi Diamond Elite Contractor—two designations that speak to our deep commitment to excellence, energy efficiency, and technical expertise. These accreditations are more than badges—they mean our technicians are trained and vetted to the highest standards, and our clients benefit from exclusive access to utility rebates, high-performance equipment, and trusted guidance on energy-saving solutions.

Whether you’re looking to upgrade your heating and cooling system, improve indoor air quality, or lower your energy bills, Castlebee has the experience and certifications to help you make informed, cost-effective decisions. We specialize in residential and light commercial HVAC, with a strong focus on modern technologies like ductless mini-splits, heat pumps, and smart thermostats.

Our technicians undergo ongoing training and manufacturer recertifications to stay ahead of industry advancements. This ensures that every service call is handled with up-to-date knowledge and precision. We also respect your time: we offer flexible, appointment-based scheduling and arrive prepared, with fully stocked service vehicles that allow us to resolve most issues on the spot—no unnecessary delays or repeat visits.

We take great pride in the long-term relationships we’ve built with homeowners, property managers, and business owners throughout the region. At Castlebee, we don’t just fix problems—we provide peace of mind. We look forward to earning your trust and becoming your go-to partner for years to come.
