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….
