Common Questions
Can better air filters help with our seasonal ozone and pollen problems?
Advanced filtration directly addresses McDonough's April pollen peak and summer ozone risk by capturing fine particulates. A MERV-13 filter is effective, but your existing flexible R-6 insulated ductwork may not handle the increased static pressure. A technician should perform a static pressure test before installation to ensure your blower motor can move adequate air without straining the system.
My Ecobee thermostat is showing an E1 error code. What should I do?
An Ecobee E1 alert indicates the thermostat is not detecting power from your HVAC system's control circuit. In McDonough, this often points to a tripped float switch from a clogged condensate drain line, a safety feature preventing water overflow. It can also signal a blown low-voltage fuse on the air handler. Checking the drain pan for water and the system's fuse are the first diagnostic steps.
Why does my AC seem to have more issues now than when I first moved in?
Your system is likely around 21 years old based on McDonough's average build year. All mechanical systems experience wear, but the high humidity here accelerates specific failures. The primary issue for systems of this age is condensate drain line clogs from algae growth. The dark, damp interior of the drain line provides an ideal breeding ground, which can lead to water damage if the secondary pan overflows.
My AC stopped blowing cold air on a hot afternoon—is this an emergency?
A sudden loss of cooling during peak heat qualifies as a service priority. For a home near McDonough Square, our dispatch from the I-75 corridor ensures a technician can typically be on-site within 10 to 15 minutes. The first steps are to check the circuit breaker and ensure the outdoor unit is running, which can help diagnose the issue before we arrive.
Why does my AC struggle when the temperature goes above 95 degrees?
HVAC systems in McDonough are typically sized for a 92°F design temperature, based on historical data. When outdoor temperatures exceed this, the system must run continuously to maintain setpoint, and indoor humidity may rise. Modern units using R-454B refrigerant are engineered for better performance in these high-ambient conditions compared to older R-410A systems, maintaining capacity and efficiency.
What does the new 14.3 SEER2 minimum efficiency standard mean for my replacement?
The 2026 SEER2 standard reflects updated testing that better represents real-world performance in Georgia's climate. While a new 14.3 SEER2 unit meets the law, higher-efficiency models offer greater savings against the local 0.14 per kWh rate. The active Inflation Reduction Act rebates, up to $8,000 for qualifying heat pump upgrades, can significantly offset the cost of these more efficient systems.
I use gas heat now—is a heat pump a practical choice for our winters?
Modern cold-climate heat pumps are designed to operate efficiently in McDonough's winter lows. The economic case is strengthened by pairing the system with the IRA rebate and shifting high-energy activities, like laundry, outside of Georgia Power's 2 PM to 7 PM peak rate window. This combination can reduce overall annual energy costs compared to a standalone gas furnace and standard AC.
What are the regulations for installing a new AC unit in 2026?
All installations require a permit from the Henry County Planning and Zoning Department. Since January 2023, new residential systems must use lower-GWP A2L refrigerants like R-454B. These are mildly flammable, so 2026 codes mandate specific leak detectors, revised service procedures, and updated equipment labeling. Only EPA-certified technicians trained in A2L safety standards can legally handle the refrigerant.
