Performed diagnostic on 18 year old Carrier. Not cooling the home. Weak airflow throughout the home. Failed component on the AC, replaced. Upstairs zone wasn’t opening allowing air the cool the upstairs. Unit will likely fail again so client is looking into upgrading unit to be more efficient and keep them comfortable. Left door hangers for discounted tune ups to all the neighbors.

Going over pricing for heat pump system to work directly off of client’s new solar on the roof. Heat pump is fully electric and give the added benefit of not only being a more efficient system but also removes the gas bill for heating the home during cold winter months. Went over different options to give client best information possible and set up a time to return and perform a full tune up on the existing system to see what will work best for the homeowners.
