Wanted to add an electronic air cleaner to address allergy issues to the A/C unit installed in a tight attic space. After accepting R&R's quote, they came to the house prior to the installation date to verify all requirements to allow a quick complete installation on the agreed date. The installing serviceman was prompt, knowledgeable, neat and made sure I understood the operation of the unit before he left. I feel satisfied that I received a fair value and would recommend them for their quality work.
