They showed up within the specified time window, and performed the work wonderfully! They also brought booties to make sure not to track mud into the house as well, which I really appreciate. Took pics before and after of both cleanings, and anything they recommended to be replaced. Very thorough with their work, and provided recommendations on what to do in the future as well. I will definitely be calling Priority One again for maintenance/cleaning!
EDIT to add:
We have been coming back to Priority One for services because of how quickly they can get to us, assess the problem and solve it. They also perform full review of our systems and provide recommendations on how to improve the system. Recently, our AC stopped working and one of the techs came by (Mike) who helped resolve the issue very quickly, took pictures and provided a recommendation on getting our system replaced by a trusted company that they use. We have been very pleased with Priority One!
