"Bob and his team were very professional. They arrived at my residence on time and spent more time than expected due to a need to replace the existing PVC venting pipe to a larger diameter. Overall I am very happy with the service performed by Bob's team. I definitely recommend his team to whoever needs heating and cooling service."

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"He ended up not only selling us a new A/C unit (on sale) but gave us an amazing deal to replace the furnace at the same time. The installation took longer than I expected - but I was provided logical reasons for the time AND the poor guys did some of the work in the pouring rain. We've only had the new system for a couple of days, but I am confident that it will be an upgrade from our previous system - especially when they said "Feel Free to call us any time, and by 'feel free' I mean definitely call us if you have any questions or issues""

"Politely said, Sparky is the boss.  
We needed electricity and HDMI ran from a cabinet in our great room up above our fireplace so we could mount a TV.  Also needed cable and electricity ran to a wall in our master bedroom so we could mount our TV on the wall. 
Sparky showed up on a Friday afternoon, five minutes early.  Assessed the situation, and before he left, said he would look into how much parts/etc would cost, and he would call me with a bid.  Sunday night I received a text from him with a bid, we set up a time for him to come for the install on 8/22 at 9am.  
Sparky showed up at 8:59, and got to work.  I came home from lunch to outlets installed where I had asked, cable ran, everything was great.  He could not find the specific outlet cover for AC / Cable, but it will not be visible once the TV is mounted, so it is not of real concern.  
I was a little uncomfortable mounting the brackets for our TV on the walls, as the studs were located in odd places - and I didn't trust myself to mount a $1,000 60" plasma anywhere that wasn't on a small stand.  ha!  
I asked if he would mind installing the mounts if I kicked him some extra $$, and he gladly obliged to stay longer than he had originally intended.  He even went so far as to use his own screws/mounting bolts that were FAR superior to the ones that were provided in the kit.
Couldn't be happier.  Should we plan on doing any other electrical work / lighting in the future, Sparky will be our first call.
