The service man who did the work prepping my A/C system for the summer season did an excellent job. He left the areass clean inside and outside. He explained what he did and gave me a check list of the things he did. He explained what MERV ratings are for filters. Something I never knew. He also gave me info on a whole house filtering system . He also gave me some info on raising my outside A/C unit off of the ground...I requested that. He was very polite and kind. A very good representative of the OHL name.
