Quick Expert and inexpensive service
Dan - Concord, CA 94521
I needed to be sure the HVAC dampers in our 2-story house were adjusted properly so that we have even distribution of cooling AC, especially during these heatwaves. Mateo came in, assessed the air coming out of the upstairs vents, and quickly discerned which dampers needed adjustment. We now have better uniform airflow across our 5 upstairs rooms and for a very minor charge.
Response from Certified Heating and Air Conditioning:
