Ensure the quote includes a permit pulled through the City of Palacios Building Department, which is required for all refrigerant changes. For systems using the new R-454B refrigerant, which is mildly flammable (A2L), the 2026 code mandates specific leak detectors, service access ports, and labeled piping. A legitimate installer will detail these safety compliance items in their proposal.

An Ecobee E1 code indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Palacios, this often points to a safety lockout on the outdoor unit due to a pressure switch fault, which can be triggered by the system overworking in high humidity or from a refrigerant charge issue related to aged components. It's a signal to call for service before a complete failure.

The 14.3 SEER2 mandate ensures new systems use significantly less energy than your decades-old unit. At the local rate of $0.14 per kWh, upgrading from an 8 SEER system to a 16 SEER2 model can cut cooling costs by nearly half. The Inflation Reduction Act provides rebates up to $8,000, which can offset much of the upfront cost, making high-efficiency a financially sound upgrade.

Palacios regularly experiences summer highs near 100°F, but standard residential AC systems are designed for a 93°F outdoor temperature. When ambient temperatures exceed this design limit, the system's capacity drops and it must run longer to maintain setpoint. Modern units using R-454B refrigerant maintain better efficiency and capacity in this high heat compared to older R-22 systems.

We can dispatch a technician from our shop near the Palacios Seawall, using TX-35 for direct access to Downtown neighborhoods. For a no-cool emergency, you can expect a service vehicle within 5 to 10 minutes to diagnose the issue, which is often a tripped safety switch or a failed capacitor in these older systems.

Addressing pollen and ozone requires a MERV-13 filter, which captures finer particles. Your home's flexible fiberglass ductboard presents a challenge, as its rough interior creates higher static pressure. Installing a high-MERV filter in this system can restrict airflow enough to freeze the evaporator coil. A proper assessment of static pressure is needed before upgrading filtration to ensure system health.

Yes, a heat pump is an excellent match. Palacios' winter lows rarely challenge modern cold-climate heat pumps, which are far more efficient than standard electric resistance heat. To maximize savings, set the thermostat to use the heat pump primarily and schedule major appliance use outside the utility peak hours of 2 PM to 8 PM, when electricity rates are highest.

A system installed in a 1979 home is now 47 years old, which is well beyond its intended service life. In Palacios, this age is particularly critical due to the Gulf's salt-laden air accelerating corrosion on the aluminum condenser coils. This corrosion slowly degrades heat transfer efficiency and can lead to refrigerant leaks, making the system unreliable and expensive to operate as it struggles against our humidity.
