Ibrahim H visited our home this morning and was extremely professional throughout. He quickly identified the problem, repaired it efficiently, and took the time to explain both short- and long-term options for us. Not only did he fix the issue, but he also provided thoughtful advice for future maintenance. We truly appreciate his expertise and clear communication. Highly recommended!

Highly recommend Donmar for anyone needing reliable HVAC service.
I had a fantastic experience with Donmar Heating, Cooling & Plumbing in Sterling! My A/C had stopped cooling, and it turned out I needed both a compressor replacement and a Freon recharge. The team was professional from start to finish—arrived on time, quickly diagnosed the issue, and explained everything clearly. They didn’t try to upsell or overcharge—just straightforward, honest service. The compressor was replaced efficiently, and once they recharged the system with Freon, my home was back to being cool and comfortable in no time. Highly recommend Donmar for anyone needing reliable HVAC service. These guys know their stuff and truly care about their customers! Great family company!
