Frequently Asked Questions
Our 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 Conestee, this commonly points to a safety lockout from a clogged condensate drain line due to algae, a tripped high-pressure switch from a dirty outdoor coil, or a failed control board. It's a diagnostic signal prompting a professional service call.
Can we upgrade our home's air filter to help with spring allergies and ozone?
Upgrading to a MERV-13 filter captures pollen and fine particulates, addressing Conestee's April peak and ozone risk. However, the existing flexible insulated ducting has higher friction than metal. Installing a high-MERV filter without evaluating static pressure can reduce airflow by 20%, causing the system to freeze or overheat. A technician must measure static pressure first.
What are the regulations for installing a new AC unit in Conestee?
All HVAC replacements in Greenville County require a permit from the Building Codes Department. Since 2025, new systems must use lower-GWP A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards: leak detection sensors, revised pipe brazing procedures, and updated manufacturer certifications for the installing contractor to ensure safe operation.
We use expensive electric heat. Should we switch to a heat pump?
For a home with electric resistance heat, a heat pump is a logical upgrade. Even with Conestee's winter lows, modern cold-climate heat pumps provide efficient heat down to around 5°F. Pairing it with a smart thermostat to avoid operation during Duke Energy's 2-6 PM peak rate hours maximizes savings. The switch qualifies for significant federal and utility rebates.
Our house was built in the 90s and still has the original AC. What should we expect?
A typical 1991 Conestee Mill Village home means the HVAC unit is 35 years old, exceeding the 15-year design life. At this age, the sealed refrigerant circuit develops micro-leaks, reducing capacity. The humid environment makes the flexible insulated ductwork and condensate drain line prone to algae buildup, which is the most frequent service call we see for systems this age.
Is now a good time to upgrade our old, inefficient air conditioner?
The 2026 federal minimum standard is 14.3 SEER2, but modern units reach 18+ SEER2. At Conestee's average rate of $0.13/kWh, the higher efficiency significantly reduces summer operating costs. The active Inflation Reduction Act rebates, with an $8,000 cap, can offset a major portion of the investment when installing a qualifying high-efficiency heat pump system.
How does our local summer heat affect air conditioner performance?
Conestee's design temperature is 92°F, but actual summer highs often exceed this by 5-10 degrees. When outdoor temps surpass the design limit, the system's capacity drops and it runs continuously to maintain setpoint. The newer R-454B refrigerant standard for 2026 offers slightly better efficiency and capacity in these high-ambient conditions compared to older R-410A.
What happens if our AC stops on the hottest day in Conestee?
A complete no-cool failure requires immediate diagnosis to prevent indoor humidity damage. Our dispatch from the Conestee Nature Preserve area uses I-385 for direct access, ensuring a technician arrives at your door in 15-20 minutes. The first checks will be for a tripped breaker, a clogged condensate safety switch, or a failed capacitor.
