Castlebee Refrigeration describes itself as a Revere HVAC company with a focus on ductless mini-splits, heat pumps and central air replacement. On Google, a 2026 customer said Bryan and his team replaced the HVAC system on the roof of a 4-story building on a narrow city street. A 2026 customer said Bryan came out during a heatwave, left to get the parts he needed and came back the same day. A 2026 reviewer wrote that Bryan and his crew explained what to expect with a heat pump installation and handled the MassSave rebate paperwork. A 2026 customer said Castlebee helped them upgrade from oil heat to mini splits, three units at a fair price. A 2026 customer said a technician named John diagnosed what their mini-split needed to get back to 100% working order. BBB lists Bryan R. Castillo as the owner and gives the business an A+ grade, without BBB accreditation. A 2026 customer said Bryan came out for an initial assessment and promised to repair the unit, then ghosted them; the family heated the house with space heaters all winter, which cost thousands in heat.
We had a very complex project (replacing the HVAC system on the roof of a 4-story building on a narrow city street) yet Bryan and his team did the replacement beautifully. Bryan is a good communicator, very thorough, considerate and polite, and those characteristics are rare among heating contractors. I’d highly recommend Castle Bee.
Bryan was wonderful! We are so incredibly grateful for him! During this heatwave, he came out and took care of us, even having to leave to get the parts he needed and came back same day. He is a very friendly man and very professional! Even our dog wanted to play with him. Thank you, Bryan!
The Owner Bryan was very accommodating and responsive in scheduling a service appointment with a technician to provide maintenance on our mini-split wall unit. Estephany was also very efficient during the initial triaging of our problem. The technician, John, was able to diagnose in short order what our mini/split needed to get back to 100% working order. John was knowledgeable, professional and a pleasure to work with. Castlebee is an outstanding customer oriented company and I would definitely recommend them for HVAC needs.
Brian was so easy to work with! He made sure we were happy with the service and the price (he gave me the best price out of everyone & I called soooo many companies on the mass save list). In the winter, the condenser had an issue with the material and he resolved it quickly and at no additional cost. I really loved working with him if I ever had a question about the rebate process or anything at all, he would always respond through text or calling almost immediately. I’m excited to use him again for the second unit in my multifamily!!
I have used Castlebee services for the last 3 plus years! The service is very good, has a great business mind and his work is very clean!
