"Rather than just replace an ailing system, they worked with me to make sure my home could be as comfortable as possible. They clearly have a lot of expertise in HVAC and venting systems. So glad I hired them!"

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"I had a great experience with Climate Heroes when my HVAC system was not cooling well and was running constantly. Miles was the technician who came out, and he quickly diagnosed the issue and explained what was causing the problem in a way that was easy to understand. He made the necessary cleaning and tune up efficiently, checked the system thoroughly, and made sure everything was working properly before leaving. Miles was professional, knowledgeable, courteous, and respectful of my home throughout the entire visit. I really appreciated his communication and attention to detail, and I would definitely recommend Climate Heroes to anyone needing HVAC service."
