How Texas Heat Affects Your AC

Did you know summer heat can have an impact on your cooling system? Air conditioning is a must for homeowners in Austin because of the hot Texas summers. Extreme heat and humidity can cause the AC unit to work harder and run longer to keep indoor temperatures cool, leading to a higher risk of breakdowns and malfunctions.

High demand for AC during hot summers can strain the electrical grid, leading to power outages or brownouts. This can further amplify the strain on your AC system, as it may need to work harder to cool your home during high-demand periods. If your AC isn’t keeping your house cold, the experts at ABA Austin can provide maintenance or repairs as needed.

To reduce the impact of hot summers on your AC system in Texas, it’s important to ensure that your unit is properly maintained and serviced regularly. This can include cleaning or replacing air filters, checking refrigerant levels, and inspecting electrical components. There are many simple ways to maintain air conditioning (link to essential maintenance article). However, having your unit serviced by professionals at ABA Austin is also important for optimum performance in the summer heat.

Is Your AC Unit the Right Size?

Your cooling system can struggle to keep your home comfortable if it’s not the right size for your home. It’s important to ensure your AC unit is properly sized for the space it is cooling, as an undersized unit may struggle to keep up with demand during hot summer months.

Determining the correct air conditioning (AC) system size for a home or building is important to ensure that it operates efficiently and effectively. An AC system that is too small may struggle to cool the space adequately, while an AC system that is too large may cycle on and off too frequently, leading to unnecessary wear and tear and higher energy bills. There are several factors that HVAC professionals at ABA Austin consider when sizing an AC system, including:
