We first discovered Lim-Ric when we had our pipes freeze, and then again, when our unit went out on the hottest day of the year. In such un-welcomed circumstance, Lim-Ric was kind (which we really needed!), helpful, fast, and knowledgeable! We signed up for their bi-yearly maintenance visit and were thrilled again with the services and suggestions on maintaining our system. We would highly recommend them, and do, to our friends!
