Questions and Answers
What should I know about permits and safety for a new AC installation?
All HVAC replacements in Weston Lakes require a permit from the City of Weston Lakes Building Department. Since 2025, new systems using A2L refrigerants like R-454B, which are mildly flammable, must comply with updated safety standards. This includes specific leak detectors, revised clearance requirements, and special technician certifications, ensuring the installation meets 2026 code for safe operation.
Is a heat pump a good idea here with our electric heat and mild winters?
For Weston Lakes homes with electric heat, a heat pump is a logical upgrade. It provides efficient heating down to our winter lows and superior cooling. To maximize savings, use a thermostat to limit its use during CenterPoint's peak rate hours from 1 PM to 7 PM. The higher upfront cost is offset by the IRA tax credits and significantly lower operating costs year-round.
With our ozone and pollen, can I upgrade my home's air filter for better air quality?
Addressing ozone and April pollen peaks requires enhanced filtration. Your home likely has flexible insulated ducting, which can handle a thicker, pleated MERV-13 filter, but only if the system's static pressure is checked first. Installing a filter that's too restrictive without verifying airflow can reduce cooling efficiency and strain the blower motor.
Why does my AC struggle when it gets above 95 degrees?
Your system is engineered for a 94°F design temperature, a standard benchmark. When ambient temperatures exceed this, the system operates continuously to maintain setpoint, and the temperature difference (delta T) it can achieve diminishes. Modern units using R-454B refrigerant maintain better pressure and efficiency in these high-heat conditions compared to older R-410A systems, but capacity still drops.
My AC seems to be working harder for less cool air. How old is my system likely to be?
Systems in Weston Lakes average 20 years old, built around 2006. This age aligns with the primary failure mode for our area: evaporator coil corrosion. The high humidity combines with trace salts in the air and water to accelerate pitting and formicary corrosion on the aluminum coils, leading to refrigerant leaks and a significant drop in cooling capacity.
What should I do if my AC stops cooling during a hot afternoon in Weston Lakes?
First, check your thermostat and circuit breaker. If power is confirmed, a technician can typically be dispatched from near the Weston Lakes Country Club. Using FM 1093, service vehicles reach most homes here within 15-25 minutes to diagnose critical issues like a failed capacitor or refrigerant loss, restoring cooling quickly.
I heard about new efficiency rules. What SEER2 do I need, and are there rebates?
As of 2026, new central AC systems in Texas must meet a minimum 14.3 SEER2. Upgrading to a higher-efficiency unit, like a 16 SEER2 model, reduces your electrical consumption against our 14-cent per kWh rate. The federal Inflation Reduction Act provides a tax credit up to $2,000, and when combined with CenterPoint Energy's $300 rebate, the net cost of a high-performance system becomes more manageable.
My Ecobee thermostat is showing an 'E1' alert. What does that mean?
An Ecobee E1 error indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In our humid climate, this often points to a safety lockout on the outdoor unit or a failed control board, preventing the system from starting. It's a specific signal that requires a technician to check high-pressure switches, low voltage, and the condensate safety switch.
