I have a Shield maintenance agreement with Southport Plumbing Heading and Cooling.
The value for the plan is fantastic! They come out and help maintain your plumbing, heating and cooling systems. Jacob from the HVAC side has come out to my home and has done an excellent job of keeping me aware of what is working well, and what I may need to keep an eye on.
Justan and Nathan from the plumbing side have also come out to my house and did the regular yearly maintenance. They too, do an awesome job of keeping me updated on how the plumbing is within my house.
I also was alerted to the battery being bad for my sump pump backup system and Justan and Nathan installed a new sump pump and a new backup system as well. The timing was impeccable as we faced a power loss for around 24 hours, and the battery was fully charged and the backup sump pump worked while we didn't have power! It was better paying for the backup system than a repair bill for a flooded basement.
To round it out, the office staff, Sarah did a great job helping me coordinate not only the visits for the maintenance, but also helped facilitate the installation of the plumbing work.
They keep giving great reasons why I'm a long term Southport Plumbing, Heating & Cooling customer!
Thank you!
