FAQs
With spring pollen and ozone alerts, can our current ductwork handle a better air filter?
High-MERV filtration is essential for mitigating April pollen peaks and ground-level ozone risks. Your flexible insulated ducting must be evaluated for static pressure; older installations often cannot handle the airflow restriction of a MERV-13 filter without causing strain on the blower motor. A technician can measure your system's static pressure and may recommend duct sealing or modifications to safely upgrade filtration.
Our air conditioner just stopped on a hot afternoon. How quickly can a technician get to our house near Evergreen Plantation?
For a no-cool emergency in the Wallace Rural District, dispatch routing uses LA-18 for direct access. From our service center, travel time to your area is reliably 15 to 20 minutes. We prioritize these calls to protect indoor air quality and prevent moisture damage, which is critical given the very humid local conditions.
We have gas heat but are considering a heat pump. Is that a good idea for our winters?
Switching from gas heat to a modern cold-climate heat pump is viable for Wallace, given our mild winter lows. The key is selecting a unit with a high Heating Seasonal Performance Factor (HSPF) rating. To maximize savings, pair it with a utility-controlled thermostat to avoid operation during Entergy's peak hours of 2 PM to 7 PM, when electricity rates are highest.
Our home was built around the same time as many in Wallace. Is our HVAC system likely to fail soon?
Homes built in the late 1980s typically have HVAC systems approaching 40 years of service, which is well beyond their expected lifespan. In Wallace's coastal climate, the primary failure mode is coil corrosion from salt air infiltration. This accelerates wear on the evaporator and condenser coils, leading to refrigerant leaks and compressor failure. Proactive inspection of these components can prevent a complete system breakdown during peak humidity.
Why does our air conditioner struggle on the hottest days, even though it's newer?
HVAC systems in Wallace are engineered to a design temperature of 92°F, which is lower than our occasional summer peaks. When ambient temperatures exceed this design limit, the system's capacity to remove heat diminishes. The newer R-454B refrigerant maintains better performance and efficiency at these higher temperatures compared to older refrigerants, but it cannot overcome a fundamental undersizing of the equipment.
I've heard about new efficiency rules. What SEER2 rating should I look for now, and are there rebates?
Federal standards mandate a minimum of 14.3 SEER2 for new installations in our region as of 2026. Upgrading to a higher-efficiency unit, such as an 18 SEER2 model, directly offsets Entergy Louisiana's average rate of $0.11 per kWh. The Inflation Reduction Act provides rebates up to $8,000, which often makes the higher-tier system cost-competitive with a baseline model after incentives are applied.
Our Ecobee thermostat is showing an 'E1' alert. What does that mean for our system?
An Ecobee E1 error code indicates the thermostat is not detecting a call for cooling from your HVAC equipment. In Wallace, this often points to a safety switch tripping due to a refrigerant pressure issue, potentially from the coastal corrosion of sensor wiring or a failing capacitor. This alert allows for intervention before a complete compressor failure occurs on a high-heat day.
What permits and safety rules apply if we install a new system with the latest refrigerant?
All HVAC replacements in St. John the Baptist Parish require a permit from the Planning and Zoning Department. Since 2025, systems using A2L refrigerants like R-454B must comply with updated safety standards, which include mandated leak detectors and specific circuit breaker requirements. These codes ensure safe handling of the mildly flammable refrigerant in your home's environment.
