    They did a great job fixing the AC. They really helped us out during a difficult situation. Highly recommend.

    We had received several quotes from other vendors and Chris and his team were able to work within our budget.

    My first step when hiring a company for a major project is always to read reviews. We received…read morequotes from two different companies, and when this company came out, the representative explained that they have been serving Port St. Lucie for a long time and that the business is still independently owned rather than being sold to a larger corporation. That's something I really appreciate because it's becoming harder and harder to find locally owned companies these days. The only frustrating part of the process was getting an updated quote. We had waited too long, and the original estimate had expired. My husband called the office several times, and each time they had to take down all of his information again because it apparently had never been entered into the system. That seemed a bit unusual, as I would expect everyone to have access to the same customer information. After discussing our options with the salesman, we decided to move forward. The installation was scheduled just a few days later. We had both the inside and outside units replaced. The crew arrived around 9:00 a.m. and finished shortly after 2:00 p.m. One of the heater components that was delivered was incorrect, but we were informed that the technician would return with the correct part. The installers were friendly, professional, and seemed very knowledgeable. I chatted with them a few times throughout the day, and they worked efficiently to get everything completed. The installation also included a new thermostat, with the cost. Now I'm keeping my fingers crossed that our electric bill will drop significantly. Our old system seemed to run nonstop, and I'm hoping this new, more efficient unit will make a noticeable difference. With the energy savings, I'm optimistic that the investment will pay for itself within a few years.

    Our A/C stopped cooling. Was making awful sounds outside, no cool air inside. I had 4 other…read morecompanies come by to diagnose the problem and give me quotes. All of them determined there is a huge leak in my evap coil, and I would need to get an entire new system for thousands of dollars. A/C Doctors was the only one to realise there was something else amiss, and to take the time and properly diagnose the issue. Turns out it was a plugged up valve. They fixed the valve for a fraction of the price of the other companies, and now my A/C is running ice cold. If you need help with your A/C but don't know who to call, this is it, this is the company you are looking for. Knowledgeable, communicative, no nonsense service. 4 other companies got it wrong. A/C Doctors got it right.

    I'd give AR Williams a mixed but fair review…read more I initially called because I have a 7 to 8 year old Mitsubishi mini split in my garage that had stopped cooling. After calling several other HVAC companies that weren't interested in working on a mini split, someone else in the construction industry recommended AR Williams. When I first called, I was told they generally don't work on mini splits either. After explaining that I also had a conventional split system in my house that needed attention and that I wasn't interested in hiring two different companies, they agreed to come out and look at both systems. The technician who came out was excellent. He was professional, courteous, knowledgeable, and took the time to explain what he was seeing. He quickly determined that the mini split had lost its refrigerant charge. After adding R-410A, we were immediately able to hear the leak coming from the indoor head unit, confirming the system had a refrigerant leak. At that point, he discussed replacement options. They preferred replacing the system rather than repairing an older R-410A unit, while I decided I'd rather look into sourcing a replacement indoor head myself. My only real complaint is the pricing model. The technician spent roughly an hour and a half at my house, and the bill came to just over $600. Coming from the construction and service industry myself, I'm accustomed to straightforward hourly labor plus material markup. AR Williams uses flat-rate, software-based pricing where each task has a predetermined price regardless of how long it takes or the actual material cost. That's simply not a pricing model I'm personally comfortable with. I don't have any complaints about the technician or the professionalism of the visit. In fact, I'd happily have him back. My decision not to use AR Williams again is based solely on their pricing structure, not the quality of the people they employ. If you're comfortable with flat-rate pricing, you may have a different experience than I did. It just isn't the right fit for me.

    This particular Johnstone Supply is located on a street that you probably wouod not drive down as…read moreyou are cruising through Fort Pierce, but that is how many of these distributors are. While retail often s teams about the importance of "location, location, location," wholesale distribution to the trades is definitely more specialized and they are not reliant on people coming in to browse and perhaps impulse buy. This location of Johnstone Supply also allows HVAC contractors to get the parts they need without traveling to a bigger city like West Palm Beach to get the equipment they need to "keep Florida cool." The staff here were friendly, professional and knowledgeable. The parking lot is a bit small and while I was there a tractor trailer was blocking the entrance on the one side. No, big deal, I just pulled in the other entrance. If you are an HVAC professional, this Johnstone Supply is a great option. Again, with them being located in Fort Pierce and you are doing a job here or in one of the towns closer by, this location can save you a trip to West Palm Beach (which would save you about an hour each way in travel). I would definitely recommend here.
