Q&A
Can my home's ductwork handle better air filters for ozone and pollen?
Your galvanized sheet metal and fiberglass duct board system generally has good integrity. However, installing a high-MERV filter, like a MERV-13 for May pollen peaks and ozone risk, can increase static pressure. A technician should measure your system's static pressure to ensure the blower motor isn't overworked, which could reduce airflow and efficiency.
What are the permit and safety rules for a new AC installation in 2026?
All installations must be permitted through the Floyd County Building Commissioner. Since 2025, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards: leak detection systems, revised service practices, and special markings on equipment, all of which a certified technician will handle.
Should I consider switching from my gas furnace to a heat pump in Greenville?
Given our winter lows and Duke Energy's peak hours from 2 PM to 7 PM, a cold-climate heat pump is a viable primary heat source. It can efficiently heat your home during most of the season. The economics are favorable when combining the system's efficiency with the available federal rebates, though a backup heat source may be advised for the coldest nights.
What happens if my AC stops working on a hot day here in Greenville Proper?
For a 'No-Cool' emergency, a technician can typically be dispatched from near Greenville Park. Using I-64, service response to your neighborhood is reliably within 5-10 minutes. The priority is to restore cooling and diagnose common immediate failures like a tripped breaker or a clogged condensate line.
My Ecobee thermostat is showing an E1 alert. What does that mean here?
An Ecobee E1 alert indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Greenville, this often points to a control board issue, a safety switch trip, or—given our humidity—a clogged condensate drain line triggering a safety float switch. This requires a technician to trace the control voltage and inspect the drain pan.
What does the new 14.3 SEER2 minimum standard mean for my utility bill?
The 2026 SEER2 mandate ensures new systems use less energy. With Duke Energy Indiana rates at about $0.14 per kWh, a higher-efficiency unit reduces operating costs. The active HEEHRA rebate, with a cap of $8,000, significantly offsets the upfront cost, improving the payback period on your investment.
Why does my AC struggle on the hottest days above 90 degrees?
HVAC systems in Greenville are designed for a 90°F outdoor temperature. When summer highs exceed this design limit, the system's capacity drops and it must run continuously. Modern units using R-454B refrigerant maintain better efficiency and capacity in these high-heat conditions compared to older R-410A systems.
My AC unit is original to my Greenville home. Is it time for a replacement?
If your home was built around the year 2000, the HVAC system is now approximately 26 years old. In Greenville, the humid climate accelerates wear, particularly on components like the condensate drain line. This line can clog from microbial growth, which is common in systems of this age, leading to potential water damage and system shutdowns.
