My 9-year-old HVAC system, originally installed by a different company, developed an issue. When I contacted the initial installer, they pressured me to replace the entire system rather than fixing the faulty coil, which was still under warranty. They also quoted an exorbitant labor fee for the replacement. I reached out to Bay Air Heating & Cooling, and Israel arrived to assist.

 

He accurately identified the issue, provided a clear explanation, and quoted a reasonable price for the repair. During the process, another component began to fail, but Israel quickly arranged for a replacement part and installed it at no additional cost. After dealing with an overpriced and unhelpful company, I’m incredibly grateful to Bay Air for their professionalism and care. I’ll definitely be calling them for future needs!

Bay Air Heating & Cooling is the honestly the best! While preparing to sell my condo, the home inspection revealed that the AC wasn’t cooling properly. I posted a request for help on Yelp around 8 PM, and to my surprise, the owner responded in under ten minutes. They sent a technician out the very next morning, replaced the evaporator coil, and the issue was resolved!

I also asked them to inspect the HVAC system at my new townhouse, which the inspector had claimed was in perfect condition. The team discovered a small leak in one of the coils (a detail the inspector missed). It wasn’t a problem at all- they fixed the coil that same day.

They were so professional, friendly, and clearly passionate about their work. A huge thanks to Bay Air Heating & Cooling for overseeing that both properties were taken care of. Highly recommend!

We hired Bay Air Heating & Cooling to install a new furnace on our family property in Marin. Israel was responsive, knowledgeable, and did an excellent job. They provide very trustworthy and reliable service. We would definitely use them again for any HVAC needs!
