Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my…read morecondo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I've ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I'm not trying to throw anyone under the bus, but I can tell they really want an honest review as I've received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).

I have a Nest thermostat and was alerted by the app. I was out of town at the time. He did quick work and got it running within 1/2 hour. Super nice guy and stayed for a bit to assure the furnace was working correctly. Southport was the only company that returned my call within minutes. I recommend Southport and Phil for quick repairs. 5 stars for service but I'm not sure if it was overpriced? They got the job done so my pipes didn't freeze and that's the important part.

This went on for days until I had a different company come out for a second opinion. The new company found that the Southport tech left the service cap off after adding refrigerant so it all leaked out!!! Southport had 3 different techs come before we got the second opinion....either it is gross incompetence or a scam!!!! You decide. I cant believe the level that they went to to try and get me to buy new unit when mine is only ten years old and worked fine until Southport came for the routine inspection. Thanks to the second opinion I have a perfectly working unit again.

For a place that has so many parts, we always have to wait for a few days for parts to come in. They are not reliable, our air conditioning failed a week ago and we have to pay around $900 for that and it just failed again and they are charging us $250 for diagnostic and we do not know how much the part will be until Monday. They said the motherboard was fried and we had to replace the whole system. If you are okay with calling them frequently for something to fail and waiting a few cold nights or hot days for them to get the part, this is the company you want to do business with. This business seems too shady. We called a different (Oak Creek Heating and Cooling) they were able to find the source and were able to fix it for under $90. Oak Creek Heating and Cooking seems more experienced and knowledgeable. I will be going with them from now on.
