HVAC Repair near Mc Vicker Ave. I was called to a small business where the owner reported that their HVAC system was making loud banging noises. After inspecting the system, I found that the blower wheel was out of balance and needed to be adjusted. I also found that the air filter was clogged and needed to be replaced. After adjusting the blower wheel and replacing the filter, I tested the system to ensure it was working properly and quietly. The business owner was satisfied with my work and happy to have a quiet HVAC system.
