Heating & Air Conditioning Estimate

Really no opinion on Chris, he was a very good explaining to me the type of system that I need in my home. I feel the price of the system is very high for my retirement budget.

I am in San Jose, California to help a client with their cooling issues. Upon inspection, I noticed that the condenser fan motor was not running while the unit was on. I changed the capacitor and added a compressor saver kit to help with the high amp draw and extend the life of their system. They also decided to become part of our annual maintenance program to help the system run more efficiently and extend its life.
