I tried Southport because I got a coupon in the mail, and the price for a furnace inspection was excellent. Everybody that I spoke to was helpful and prompt. The technician was knowledgable and he explained everything in detail while showing me photos of each aspect of the system. I appreciated the kindness and expertise of the technician, and I will definitely call on Southport again.
