Top HVAC Mistakes Explained
1. Incorrect System Sizing
Many Texas homes end up with systems that are either too large or too small. Oversized units short-cycle, while undersized units run constantly. Both waste energy and increase wear.
2. Poor Ductwork Design
Texas homes—especially larger suburban layouts—require carefully designed ducts. Poor design creates hot and cold spots and higher energy bills.
3. Refrigerant Mischarge
Improper refrigerant levels can ruin efficiency and even damage your compressor. This mistake is more common when unlicensed or rushed installers do the work.
4. Skipping Permits and Inspections
Cities like Austin, San Antonio, and Georgetown require HVAC permits. Skipping this step not only risks fines, but it can also void warranties.
5. Thermostat Placement Errors
Placing thermostats near windows, kitchens, or vents can cause inaccurate readings, making your HVAC run inefficiently.
6. Rushed Installations Without Testing
A quality HVAC installation in Texas should always include testing airflow, duct pressure, and thermostat calibration. Cutting corners here means future headaches.
Personal Insight #1:
I once inspected a San Antonio home where the AC unit was oversized. It cooled the home too quickly without removing humidity, leaving the house clammy and uncomfortable.
Personal Insight #2:
In Georgetown, a homeowner hired a cheap installer who skipped permits. Months later, the city inspection flagged the job, and the homeowner had to pay extra to fix it.
