Upon arrival, customer wanted me to install ecobee tsat. Currently had a t6 Honeywell tsat. Replaced tsat and mounted the new ecobee tsat. Made sure the unit was operating fine with the new tsat. Test it in cool and heat and it’s working great. Recommended a surge protector and uv light for being a new home and keeping the unit up to date. Customer declined uv light and surge protectors. Recommended maintenance also said he will thinking about. Customer paid $159 with card for installing customer provided ecobee tstat.
