Yelp review
Ronald W. · Nov 17, 2022
The reviewer said a $49 inspection did not identify the water heater problem, which another company found quickly, and that Mission's $3,200 quote for a 50-gallon heater was about $800 above seven other companies they called.
Ask before booking: Ask for the water heater options and prices in writing, and confirm that a plumber (not only an HVAC tech) is assigned for your appointment date.
