FAQs
Should I switch from my gas furnace to a heat pump?
For Shady Hollow, a dual-fuel system pairing a heat pump with your existing gas furnace is often optimal. The heat pump handles moderate winter temperatures efficiently, while the gas furnace provides reliable heat during our few freezing nights and avoids costly operation during Austin Energy's 3-8 PM peak hours. This setup maximizes comfort and operating cost savings.
What permits are required for a new AC installation?
The City of Austin Development Services Department requires a permit for any new HVAC system installation. As of 2026, systems using A2L refrigerants like R-454B must comply with updated safety codes for leak detection and ventilation due to the refrigerant's mild flammability. Using a licensed contractor ensures the installation meets all current codes for safety and efficiency.
What's your response time for a no-cool emergency in Shady Hollow?
For a no-cool call in Shady Hollow, our dispatch from near Slaughter Creek Metropolitan Park uses TX-1 Loop (MoPac Expressway) for direct access. This routing typically ensures a technician arrives within 15 to 25 minutes. We prioritize these calls during heat advisories to prevent indoor temperatures from rising dangerously fast.
My system is from the 90s. Is it time to replace it?
A system from the 1990s in Shady Hollow is approximately 39 years old, well past its typical service life. Units this old operate with outdated R-22 refrigerant, which is no longer manufactured, making repairs costly. The extreme Texas heat cycles cause capacitors and contactors to fail frequently in aged systems. Proactive replacement avoids emergency breakdowns during peak cooling season.
Why does my AC struggle on the hottest days?
Central Texas regularly exceeds the standard 97°F design temperature for HVAC equipment. When outdoor temperatures climb above 100°F, the system's capacity drops and it must run continuously. Modern units using R-454B refrigerant maintain better efficiency and capacity at these high ambient temperatures compared to older refrigerants, but all systems have a performance limit.
Can my home's ductwork support a high-efficiency air filter?
Many Shady Hollow homes built in the late 80s have flexible R-6 insulated ducting, which can be restrictive. Installing a high-MERV filter, like a MERV-13 for pollen and ozone particles, increases static pressure. A technician must measure your system's static pressure to confirm it can handle the filter without reducing airflow or damaging the blower motor.
My Ecobee thermostat is showing an E1 alert. What does that mean?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Shady Hollow, this is commonly caused by a failed control board or a blown 24-volt fuse, often due to a capacitor failing in the extreme heat. This signal means the system is inoperative and requires a technician to diagnose the electrical fault at the air handler or furnace.
What SEER2 rating should I look for in a new unit?
As of 2026, federal law requires a minimum of 15.2 SEER2 for new central air conditioners in Texas. Given Austin Energy's rate of $0.14 per kWh, a higher SEER2 unit, like an 18 SEER2 model, significantly reduces operating costs. The federal HEEHRA rebates, with caps up to $8,000, can make these high-efficiency systems very cost-effective when combined with local utility incentives.
