Andrew W. was very efficient, friendly, and even took mercy on our dog, allowing me to let her roam during his visit to lessen the barking.

I had my annual Heat Pump AC checkup today (8/26/26) by Southport. As always, their technician Zach Birkholrz did a thorough and excellent job. Zach is very pleasant and professional and explains the checkup process and results very clearly. And, as a bonus, he gets along with our dog.
Joe Suchla replaced our two outside faucets and main water shut-off today. The rear faucet was only accessible from a basement crawl space, so he installed a secondary shut-off valve in the baseme t so I did not have to enter the crawl space to shut off the faucet in the winter months. He also bought the main water shut-off up to code with a shut-off valve on each side of the meter. Joe arrived on time, performed all plumbing upgrades professionally, kept me informed of the upgrade progress, and cleaned up at the end of the job. We are very pleased with the job Joe did and have always been pleased with the work Southport has done for our plumbing and HVAC needs. We highly recommend Southport.
Jackson did an excellent job of system check of our AC. He explained everything he checked and the meaning of all test results. A very friendly and professional service tech. Highly recommend SouthPort and Jackson.
