What Your Neighbors and Business Owners Say About Us

I was waiting to hear from another HVAC/plumbing company and they never responded.
South County responded in a timely manner and were able to get the job done. I needed my kids’ bathroom tub drain cleaned out and they fixed the drain. My girls took a bath tonight and the water drained fast. Great job!

Leaky dryer vent in attic. South County was quick to address the problem. They listened to our concerns about what was happening and rectified the issue which was brushed off as nothing by another company... Really saved us! Owner followed up with us in the days following to check on us and make sure everything was running smoothly which was awesome.

The service was great! Our shop boiler went out right before the first cold snap of the year and they had us back up and running in no time. Thanks again for the great service.
