    I HIGHLY recommend calling Claude if you have any AC issues. He was able to come out the same day…read moreand was right on time. He quickly diagnosed and fixed the problem(something Fogel Services could not do, even though they charged me for service...I would absolutely NOT recommend wasting your time with them). Claude is very knowledgeable, efficient, friendly, and gave some great tips. I can't recommend him enough.

    We had a very bad experience with Southern Seasons Heating and Air Conditioning.  It is our feeling…read morethat we were defrauded by the owner Claude McAlhany, who is also the technician that came out.  Our air conditioner stopped working on Labor Day weekend.   Claude came out and claimed to have added 13 lbs of freon at a cost of $1950.  It did not fix the problem.  He came back the next day and said the control board had to be replaced and charged us an additional $2,075 for replacing it.  This also did not fix the problem. When we called Claude back, his son texted us that his father had a heart attack and was at a hospital in Columbia.  I have no idea if this is true, but it seems suspect, as he clearly had no intention of coming back to fix our unit.  We then called Aptus HVAC.  The technician informed us that our air conditioning unit could only hold around 7lbs of freon and there is NO WAY it could hold even close to the 13lbs for which we were charged.  He also said that the control board was NOT new and had about 4 years of dust on it.  Needless to say, we were devastated that we had clearly been taken advantage of.  Aptus went into the attic - something Claude never did - and replaced the motor at a cost of $450.00.  We called Claude back and told him what we learned about the work he did.  He was defensive and said that we don't know what we are talking about.  He said that the unit may take 7 lbs. but we have to account for the coils and the piping to the house.  We did our research on our unit and learned that standard R-410A systems require about 0.6 ounces of extra refrigerant per foot of copper piping over the standard 15 feet. To need an extra 5.6 pounds, our indoor and outdoor units would have to be roughly 160 feet apart. This is incredibly rare for a residential home and especially for a home of our size, which is only 2100 SF.  We were clearly taken advantage of and overcharged.  When we asked about the control board, he claimed that maybe the box was open and that it might have gotten dusty sitting in his truck or that it got about four years of dust in the 4 days between when he installed it and Aptus came out.  His theories are not credible.  I should have verified if he was licensed before we hired him.  After the fact, I could find no record of him being licensed with the State of South Carolina, Charleston County or the town of Mount Pleasant.  When asked on the phone if he was licensed, his response was "Here is my license number, kiss my ass".  He then texted and said "don't ever contact me again".  Later that night he attempted to explain the 13lbs of freon with some shots of a Google search - but the data he provided was on a much larger unit than we own.  When I pointed that out - he went silent again.  I don't really understand how he thought he could get away with so brazenly ripping us off.  Maybe he saw two older people and thought we wouldn't figure it out. In any case, use caution and do your homework if you hire Southern Seasons.

    Thank you Holy city HVAC from the first day I called your company I knew I made the right decision…read more From the time I contacted the company they guided me through the process for repairs or replacement. From Blake organizing the project from beginning to the end of the project was simply professional along with humor, I watch the installers from my camera and it was no time for goofing off. job well done ! The office staff were very respectful and professional. Thank you Bernadine

    It was Sunday evening when I discovered a plumbing problem at the house. I decided to put out a…read morerequest a quote through Yelp so I could see who was available and get some pricing for Monday morning. I've had this issue happen years ago so I was pretty confident in the fact that I needed my main line snaked/augered. I feel like the whole point of doing these requests is to get the info you need without a bunch of phone calls and visitors to the house, but it feels like pulling teeth trying to get a quote out of someone. I understand there are variables, but I'm including a description of what I need... at least give me a ballpark. While Holy City is one of the ones that would not offer any pricing, they did offer a free estimate and they also got back to me Sunday evening within minutes of putting in my request. I went back and forth on the app and set up an appointment for Monday morning between 10am-12pm and was told I would get a text 30 mins before to let me know someone was on the way. Well 10-12 came and went with no tech, no call, and no text. I did shoot them a message at that point letting them know that nobody came. A while later, they sent me a message saying that my appointment time had changed and would now be between 3-5pm. No apology or acknowledgement of the missed appointment from that morning. So I replied, "No thank you. You already no call/no showed our first appointment". I get no response on the app so I figure what's done is done. Then I get a text around 3:15pm letting me know a tech is on his way to my home. I responded with a shortened version from above and that I no longer wanted service. Then it seemed I was getting a new message from an Aaron D stating he canceled the appointment and was sorry for the confusion about my appointment. I pointed out that there was no confusion about the appointment and that I was ready and waiting the whole time to which their tech no call/no showed. Then they just reschedule me for 5 hours later with zero explanation or apology. At that point, the problem was already fixed by another plumber from another company who was more reliable. From there, Aaron did apologize for the inconvenience and acknowledged that the mistake was on their end and he would deal with it internally. Based on other reviews and the quick response to my initial inquiry, I was really looking forward to a great experience. Maybe this was a fluke for them, but I can only go off of the experience I had and it was quite disappointing. I'll add an extra star for Aaron reaching out to remedy the situation and acknowledging their mistake, but I won't be recommending them to anyone else.

I knew I needed an HVAC company but had zero experience w/ any in the area. I submitted a Yelp query and quickly heard back from Lisa. I explained what I needed and she scheduled an appt to assess and talk estimates. Corey arrived on time and was extremely knowledgeable and helpful. I needed two intake vents replaced, one was a custom size. And I needed 12 "boots" and grates replaced on the vents. I had tried to do this myself and it was just impossible. Corey explained what was needed and we discussed the price. Jump ahead to the work day. I needed to run some errands so I phoned the office to confirm arrival time. Lisa was quick to find out the answer and let me know. Around 10AM, per plan, Maurice and Marquis arrived. The work required hours of being on site and they were quick to get started. To say replacing the vents was difficult would be an understatement but they got it all done. Their work also involved doing a cleaning on the system. I would highly recommend these guys. From Lisa in the office, to Corey who did the estimate, to the Maurice / Marquis the install team. Just a great job ... all attentive, knowledgeable, and professional.
