Q&A
Is it worth upgrading our AC for efficiency with current electricity costs?
Yes. The current 15.2 SEER2 minimum standard represents a significant jump in efficiency over older units. At Black Hammock's average rate of $0.14 per kWh, a modern 18-20 SEER2 system can cut cooling costs by over 30%. The active federal HEEHRA rebates, with caps up to $8,000, directly offset the upgrade cost, improving the payback period substantially.
Our Ecobee thermostat is showing an 'E1' alert. What does that mean here?
An Ecobee E1 code indicates the thermostat is not detecting a call for cooling from the indoor unit. In Black Hammock, this often points to a safety lockout on the control board due to a corroded evaporator coil causing a pressure switch fault, or a failed condensate pump in the high-humidity environment. It's a specific signal that professional diagnosis is needed to prevent compressor damage.
We use electric heat strips now. Should we switch to a heat pump in Black Hammock?
Absolutely. With winter lows around 49°F, a modern cold-climate heat pump is far more efficient than electric resistance heat. It can provide all necessary heating at a fraction of the cost. Programming the thermostat to avoid auxiliary heat use during Duke Energy's peak hours (1-6 PM) maximizes savings. The transition qualifies for the same federal incentives as a high-efficiency AC replacement.
Our AC is original to our 1988 home. Should we be concerned?
A 38-year-old system is operating well beyond its intended lifespan. In Black Hammock's humid, salt-air environment, the primary failure mode is evaporator coil corrosion. The aluminum fins and copper tubing degrade from constant moisture and airborne salts, leading to refrigerant leaks and a complete loss of cooling capacity. Proactive replacement avoids a catastrophic failure during peak summer heat.
What should we verify about permits and safety for a new R-454B system?
All HVAC replacements in Seminole County require a permit from the Building Division. For 2026, this is critical because R-454B is an A2L mildly flammable refrigerant. The permit process ensures the installation complies with new safety standards for leak detection, ventilation, and line set placement that are mandatory for A2L systems. Using a licensed contractor guarantees this compliance and protects your home insurance.
Why does our AC struggle when it hits 95°F, even if it's working?
Central Florida systems are typically designed for a 93°F outdoor temperature. When ambient air exceeds this design limit, the system's capacity drops and it runs continuously to try to meet the thermostat setting. The newer R-454B refrigerant has a slightly lower discharge temperature than older R-410A, which helps compressor longevity during these sustained high-load periods, but cannot overcome the fundamental physics of the design temperature gap.
Our AC just quit on a Saturday. How fast can a technician get to Black Hammock Island?
A no-cool call is treated as a priority. Our dispatch uses SR-417 for direct access from the Little Big Econ State Forest area to the island. Accounting for weekend traffic and the specific bridge access, a technician will be on-site within 25 to 35 minutes to diagnose the issue and restore cooling.
Can our home's ductwork support a high-end air filter for pollen and ozone?
Flex duct with standard fiberglass insulation often has higher static pressure. Installing a restrictive MERV-13 filter for April pollen and ozone mitigation can strain the blower motor, reducing airflow and efficiency. A technician must perform a static pressure test. The solution may involve sealing duct leaks or upgrading to a media cabinet with a larger filter surface area to maintain proper airflow.
