They have been caring for our furnace for over 15 years and have never let my family be cold during the long and brutal New England Winters!

My air conditioner stopped blowing cold air Saturday evening. Of course it's supposed to be the hottest days for the next week for the summer of 2025. Called them for an emergency repair. Craig called me back. Said he'll try to get there. As soon as possible was at my house within 20 minutes. Did the repair and got us back up and running. Good company to have. read more

Castle Heating and Air Conditioning are fast, efficient and professional. I had an immediate situation with a furnace cleaning and they got me right in as they promised. Great family run business! read more

I'll pay twice the amount to someone else before using this person. (They are expensive as well) His answering service was more professional and polite then him (Craig Sr.). Unfortunately my heat went out during the weekend. It's not strange to have to pay extra for emergency weekend service. Craig's service charger $200 for service call "up to an hour". Changed the compositor ($75.00) heat came back on. Total time less than "10minutes". Total charge $293. He said it was very dirty and need cleaning $600.00 or total replacement. I told him ok, clean it. He declined said he doesn't have time, he has other service calls and my heat is on now. 2hrs later no heat. I called him back and he said he'd come out in the morning . Spoke at 8:30a he said it's dirty, he'll need to do a,b,c,d..... what do I want him to do? Meaning charge me more money (not an issue if he would've done it when he came out the 1st time). I refuse to put more money in his pocket for a rip-off job to start with. He was very rude from the start. I don't know if it's just towards women. But I definitely felt taken advantage of, spoken to rudely and ripped off. read more

Can't understate the importance of a company like Castle Heating and AC. Fall into winter is the busiest time of year for this type of company and they made my job (which could be considered as small) seem very important. All I needed was a new valve and an air vent on my boiler (which also does my heating for the house.) I let them know it wasn't an emergency, they scheduled me out the soonest they had. When the tech Juan got here he made sure to explain everything he was going to do and WHY. Very efficient work. Everything was all done in about two hours. They even came out briefly a couple weeks prior to bleed the air out of my system and didn't charge me for that. It was very generous. Their prices are fair, their work is good and I would recommend them to anyone in the area needing heating and AC work done. read more

Requested estimate and service. Left all information with person at customer service. It's been a week, nobody reach out back to me. I guess busy enough so don't need new customers. Found good service elsewhere. read more

A little late with my review but had to share how satisfied we are with the work Craig and his father did for my parents condo back in June. Unexpected breakdown of ac. Showed up right away even though we were not existing customers. Complete new cooling system in the middle of a heat wave so we knew how busy they were. Craig was honest and up front with estimate & Craig Jr. gave us his word to fit us in within a week and sure enough came through. Thank you for taking care of my parents! read more

They came during a heat wave on short notice. Great company, a pleasure to talk with and amazing customer service. 10 stars recommendations!!! We where not existing customer but now we will. Thank you, Criag Jr and father. read more

Knowledgeable !!!! When I purchased my new home with radiators I called him to service my gas furnace. He spent time to explain about my furnace and radiators. What he told me to do was the correct information, he is so honest. You will be very happy with Castle Heating!! read more

Called since outside unit was disintegrating and system not cooling well. Assumed we needed a whole new AC system. Technician very professional, friendly and honest. Added refrigerant, cleaned outside unit, completed inspection and told me I was good for probably another 5 years til my next 'tune-up' and 10 years on the current unit. Very thorough and explained everything step by step. Highly recommended for your AC and heating needs!!!!! read more

When our boiler broke down near the end of a very cold winter five years ago, we received a word-of-mouth recommendation for Castle Heating & A/C. The principal of the company came out quickly, gave us a range of options, and quickly produced a competitive quote. We were impressed with their professionalism and gave them the job to replace our boiler. They were able to come in the morning, break down the old boiler, and have the new one running by the evening time. It never ran better than it does now, and after five years I can report flawless, uninterrupted service. In the intervening time, we've had various tradesmen in the basement, including the gas company technician, and each and every one comment on how good the components are, and that whoever installed them did a fantastic job. That's Castle Heating & Air Conditioning's work. We've also had them out to install a valve for a gas line--they were so accommodating, and came out on short notice. Although your job may be more complex, and take more time to install than ours did, I just can't say enough good things about this family-run business and the great service we've received from them over the years. You can count on excellent quality and service at a fair and correct price. Highly recommended. read more
