Fixed my A/C on the spot Feb 12, 2025

Our A/C went out around midnight in the middle of this record-breaking heat. I called Advanced Air Conditioning the same night after seeing online that they are local and take calls 24-7. I didn't get someone here that same night, but I got a call back at 8 a.m. telling me that someone was on the way. Help arrived around 8:30ish and fixed my A/C unit on the spot. The air was running within half an hour. I think they did all they could in the fastest manner possible. I was very satisfied with the service that I bought their yearly plan to check my heater in the winter and A/C in the summer and got 20% off my bill, which I thought was reasonable.

Advanced Air Conditioning and Heating Jan 24, 2025

Hi All! While I love most things about my GFO home, there are a few challenges I’ve faced. One of the more frustrating ones has been my HVAC system, particularly with unbalanced heating and cooling in my home. The biggest issue is that while most of the house stays comfortable, my daughter’s room becomes too hot in the summer and too cold in the winter. After trying three different companies without success, I finally found a group of professionals who not only understood the issue but also provided a solution and explained it in a way I could easily grasp. The company is called Advanced Air Conditioning and Heating. Here’s what I learned from these fine people: Your HVAC system starts with return ducts, which are flexible tubes or conduits that pull air from your rooms back into the system. This air flows into the return plenum, a chamber where I installed a filter a few years ago to replace the builder’s original inlet filtration system. The return plenum directs air into the air handler, or furnace, which is the system’s core. Inside the air handler, a blower fan pressurizes and circulates the air. For heating, the air passes over a heat exchanger, warming it with gas, electricity, or another energy source. For cooling, the air moves through an evaporator coil, where refrigerant absorbs heat, lowering the air’s temperature. The conditioned air then flows into the supply plenum, a box-like chamber that distributes it into the supply ducts. When air exits the blower, it’s fast-moving and chaotic, creating turbulence. The supply plenum’s job is to calm this chaotic airflow, converting it into steady, evenly distributed static pressure. This static pressure is what pushes the air effectively through the supply ducts, which are often long, flexible columns that lead to the vents in each room. Proper duct placement is key to ensuring efficient airflow. Surprisingly, placing ducts close to the air handler, which might seem logical, actually reduces airflow. This is because the air near the blower is still turbulent and hasn’t stabilized. These ducts rely on dynamic pressure, which is less effective than static pressure for distributing air. Additionally, high-velocity air tends to bypass nearby ducts, creating 'dead zones' of weak airflow. In contrast, ducts positioned farther along the supply plenum benefit from stabilized pressure, resulting in stronger, more consistent airflow. To improve system performance, it’s important to space ducts evenly along the supply plenum, attach them to the sides instead of the top, and, when needed, use dampers, which are movable plates inside the ducts, to fine-tune airflow. This ensures a balanced system that serves all rooms effectively. Finally, the air circulates back to the return system, completing the cycle. In my case, the builders made several choices that contributed to the imbalance in my daughter’s room. They placed the duct on the supply plenum too close to the air handler, where turbulence is highest. They also attached it to the top instead of the side of the plenum and used only one branching duct to supply her room instead of installing two direct ducts from the supply plenum. If you’re experiencing a similar issue, I recommend giving Advanced Air Conditioning and Heating a call at 512-382-6745. That said, you might want to wait a week and I’ll provide an update once I’ve had a chance to confirm if their redesign works as planned. Remind me if I fail to do this….

I called for an emergency Saturday appointment and received a home visit within an hour. Since then, I have received excellent, prompt, and consistent service with the same technician visiting about 3 times due to ongoing rodent issues. Shout out to Bruce S. who has had to deal with the rodents firsthand! He has been so professional, informative, and kind during this stressful time. Thank you to Bruce and the team!

Very nice and professional service Oct 14, 2024

Justin came out to my residence on 14 October 24 with a coworker. Diagnosed issue and completed what needed to be done. Both were very nice and professional. Justin explained everything that was wrong with my AC unit and what needed to be done. He also suggested options and advised me as to what needed to be done going forward. Both were nice to work with. Thank you for your service, guys.

Signed up for annual membership Oct 7, 2024

My tech, Joe, was very friendly and put me at ease. He showed me everything we needed to fix and some items we can do at a later date. I felt so comfortable I signed up for the annual membership. Booking, service, and payment all easy.

Blair Elder

Fast, thorough, and friendly! Oct 4, 2024

Fast, thorough, and friendly! I had an issue with my AC not giving cold air. I called Advanced Air Conditioning and they sent a tech out the same day. The tech, Joe Martel, was able to quickly identify the issue with my new thermostat. This issue was resolved very quickly by adjusting the wiring. Then Joe Martel wanted to confirm everything was working. He ran a few tests inside/outside the house replacing any parts, but explained the reasoning 'why' before making any changes. Overall, I'm happy with choosing Advanced Air Conditioning for my issue, and glad the team responded quickly!

Cold air in 15 minutes! Sep 20, 2024

I had an emergency service request at 7 p.m. to replace the capacitor on my A/C unit. I called 5 companies from Google that claimed 24/7 service. None of them could come out until the following day, and it was already over 80 degrees inside my house. This happened to be the 6th company I contacted. The office told me that someone would call me back about service, and I thought, great... how long is this going to take? Less than 5 minutes later, Justin calls me and says, "I'm leaving immediately and I'm less than 30 minutes from you." Justin was a pleasure to deal with. Professional, respectful, and very knowledgeable! He had cold air blowing through our vents in less than 15 minutes. We slept great last night! I highly recommend Justin and this company for any heating and A/C work you need done!
