We have been using R & R Mechanical for years. When our air conditioning died years ago, Ramon came to the rescue. Have been using them ever since to perform routine checks of our heating and air conditioning systems. They work with you on scheduling. When they had to work on outside system and it was pouring, they called to apologize and reschedule the appointment. They call to say they are on their way. Ramon & the other workers are professional and courteous. Highly recommend this company.
