    This is a family owned business. In an industry that doesn't always feel honest, both Carl and…read moreCallie come across as genuinely sincere, genuinely helpful, and they have never seemed to be just out for a buck. Quite the opposite, they have proactively given us tips that no one else had ever offered us (and we have always had yearly AC tune ups) to keep our AC units running longer. We appreciate this and respect them and their business. Just good, honest people.

I was looking to replace my entire AC system which is why it's important to find the best in the business and rated the best. It's also important to find more than one 5* business so you can get a better picture and quotes for such an expensive endeavor which I found helpful. If you're going to go all the way with such an expense, it's best to educate yourself as much as possible, and there's lots of YouTube videos on AC repair and replacement which you should watch prior to making that decision. You really need to be an informed and educated customer or you might find yourself with an inferior or wrong system. I found that certain AC companies want the steer you to certain brands they represent, so you may wish to decide on a brand first. I found that the Carrier Infiniti system with its very high seer rating and variable speed was the perfect choice. More details on this system in the photos below. If you live in a two-story house like mine, you can expect the price to be much greater due to the fact that you have dampeners which will need to be fixed or replaced which greatly adds to the bill. As for my AC, it was over 20 years old, but still chugging along. However, I knew there was going to be new mandates in 2025 which would greatly add to the expense of AC replacement such as a new refrigerant which is slightly flammable called Puranovance. I replaced my old R22 compressor with the new R-410a which is still readily available, but will eventually be phased out many years from now. I also mistakenly thought you'd get a good deal by replacing it during the cool months, but apparently a lot of people were doing what I was doing so no break in the price. As a matter fact, the date of manufacture of my new Infiniti compressor was only just a couple weeks old before it was installed. After some back-and-forth on pricing, we finally decided on a date of installation. Carl and his crew showed up and had everything installed within six hours and hauled off the old units. We still needed some troubleshooting in order to dial-in the thermostats functioning properly, but everything works perfectly now and the temperature remains exactly as you set it throughout the house. Both the compressor and the blower motor are incredibly quiet. Since I knew I needed this replacement at some point, I had enough money in the bank to cut a check for the job. When you sign up for Carl's service, you get Carl in the equation. Check out the photos below which show you the equipment, specs and the pricing. Update: After 2 weeks the plenum did separate, but I was able to use foil tape to close up the 8" gap. Personally, I think a 30 day check up would be a good idea not just for Carl, but anyone who gets this kind of installation from whatever company you choose.

    The Good Apex deserves credit for their emergency…read moreavailability and quick response time. When my A/C failed at 2AM on a Sunday, they were the only company able to come out immediately (I called at least 5 others). The technician arrived promptly, diagnosed the problem efficiently (faulty fan motor on my Carrier unit), and completed the repair within a couple hours, including a trip to source the part from their vendor. The Concerning The final cost was $2,303.60 for what I've since learned should typically cost $700-$1,000 (that is including emergency service fees). While I understand emergency calls command premium pricing, this felt excessive. Additionally, the quoted price increased from $2,000 to $2,303.60 when it was time to pay without clear explanation of the additional charges. My Takeaway Apex delivers on availability and technical competence when you're in a crisis. However, I'd strongly recommend getting multiple quotes if time permits, as their emergency pricing appears significantly above market rate. The convenience of immediate service came at a steep premium that I wasn't prepared for. Would I use them again? Only in a true emergency where no other options exist, and I'd request detailed pricing breakdowns upfront. For future customers: Get clear, written estimates before work begins, and ask about all potential additional fees.

    Jacob and Bryan did an excellent job on my spring HVAC check-up. Since I had a new system installed…read morejust a few months ago (by Service Wizard), it was reassuring to see everything running perfectly. They took the time to thoroughly clean the condenser and ran multiple tests on the attic unit to make sure everything was operating as it should. What really stood out was how they walked me through the entire process at the end, showing photos and explaining each step. It gave me a lot of confidence in their work and attention to detail. I'm very happy with this company and would highly recommend them.

    **1/5 Stars - Big Waste of Time (and almost a lot of money)**…read moreI wanted to like Service Wizard, but my experience with them was incredibly frustrating. My AC condensation pipe was completely backed up and needed to be flushed. Their tech arrived on time and seemed very professional, spending about an hour and a half working on the unit and inspecting everything inside and out. However, he couldn't find where the evaporator line exited the house. His solution? Install an external pump and run a whole new drain line. The rough estimate for that was, well, a hell of a lot more than the $15 fee they charged me just to come out and take a look. When he left, I still had the exact same broken AC, was stressing over an exorbitant bill to fix it, and somehow found out I'd been signed up for a $15-a-month service plan that entitled me to another check-up in six months just in time for winter. Hoping to just get it resolved, I reached out to Service Wizard via Yelp later that evening to see if they could come back today to do the work the tech recommended. I never got a response. Frustrated, I called a different AC company. They actually answered the phone, sent technicians out right on time today, and those guys spent **five minutes** at my house before finding the external line, repairing it, and flushing my system. Problem completely solved in under five minutes, and the fee was incredibly cheap compared to the massive quote I got from Service Wizard. I will definitely be canceling my $15-a-month contract with Service Wizard and won't be recommending them going forward. Save yourself the headache and call someone else!

Sorry for the long review...but please read on to hear my horror story with this sorry excuse of a company. I don't normally write reviews (good or bad), but my poor experience with this company cannot go unheard. I feel obligated to warn others of their frankly criminal business practices. I originally called them out to take a look at my old HVAC that was no longer producing cold air. They identified the Freon was low and filled it back up. Worked well for a bit, but then got low again...indicating their was a leak in the system. The unit was so old, we decided to replace the unit instead of fixing it. The new unit was installed, but not without issue. I chose what they described as their go-to brand - American Standard. Apparently their technicians do not know how to install their go-to brand, because it took several days and several different technicians to get the install completed. A year later, the unit began tripping the breaker any time it went to the 2nd stage. Took them 3 days to come out (when approaching triple digit temperatures), charged $150 service fee and $450 in parts and labor to add a capacitor to the setup (a $50 part and about 10 minutes of labor). Did not fix the problem. Tech came out again, and said it seemed to be an issue with the breaker and that I needed to call an electrician to diagnose and solve the problem. Ended up paying $300 for an electrician to come out. When he took a look at the install, he was flabbergasted. He could not believe what he was seeing! He identified the unit was installed on an aluminum electrical line, that was severely undersized for the unit installed. He said no respectable company would EVER do this kind of shotty work. He said replacing the electrical line would likely cost a couple thousand dollars, since it was on the other side of the house. When I called Smart Air to let them know of the situation, the dispatcher was very dismissive. She said she would have their lead install tech follow up with me, but of course I never heard anything back... That is when they went dark despite several additional attempts on my part, and broke communication with me entirely. I ended up having to pay an electrician to run the new line on my own dollar - several thousand dollars - and now I'm finally back up and running.
