Frequently Asked Questions
Our summer highs can hit the 90s. Is an 88°F design temperature for my AC sufficient?
An 88°F design temperature is the outdoor condition at which your system should maintain 75°F indoors. During hotter periods, the system will run continuously to keep up, which is normal. Modern units using R-454B refrigerant maintain better capacity and efficiency at these higher temperatures compared to older R-410A systems, providing more resilient performance during our peak heat.
Can my older sheet metal ducts handle a high-efficiency air filter for pollen and PM2.5?
Your home's galvanized sheet metal ductwork has a structural advantage for airflow. However, installing a MERV-13 filter to capture May pollen peaks and fine particulate matter (PM2.5) increases static pressure. A technician must measure your system's static pressure to ensure the blower motor can overcome this resistance without reducing airflow or causing the evaporator coil to freeze.
What are the local requirements for installing a new AC with R-454B refrigerant?
All installations of equipment using A2L refrigerants like R-454B must follow 2026 UL 60335-2-40 safety standards, requiring specific leak detectors and service practices. In Rock County, a permit from the Planning, Economic and Community Development Department is required for the replacement. This ensures the installation meets updated codes for the safe handling of this mildly flammable refrigerant.
Is the new 13.4 SEER2 minimum efficiency standard worth the investment with current electric rates?
Yes, the 2026 SEER2 standard represents a significant efficiency jump. At Fulton's average rate of $0.15 per kWh, a new 16 SEER2 system can cut cooling costs by roughly 20% compared to an older 10 SEER unit. The federal HEEHRA rebate, with incentives up to $8,000, directly offsets this higher upfront cost, improving the payback period.
If my AC quits on the hottest day, how fast can a technician get to my home in Fulton?
A dispatch from our shop near Fulton Town Hall provides a consistent 10-15 minute response to most Fulton Village Center addresses. Using I-39/90 for quick access across Rock County, we can typically diagnose a no-cool emergency like a tripped breaker or failed capacitor within that first visit, restoring comfort promptly.
My Ecobee thermostat is showing an E1 alert. What does this mean for my Fulton home?
An Ecobee E1 alert indicates the thermostat is not detecting voltage from your HVAC system. In a Fulton home, this commonly points to a tripped safety switch on the condensate overflow pan, a blown 3-amp fuse on the furnace control board, or a complete system power loss. It's a protective signal preventing operation until the electrical fault is resolved.
When does it make sense to switch my natural gas furnace to a heat pump in Fulton?
Consider a dual-fuel system pairing a heat pump with your existing gas furnace. The heat pump handles cooling and efficient heating down to about 30°F, avoiding the 14:00-19:00 peak electricity rates. Below that, the gas furnace provides reliable, cost-effective heat during our coldest nights, optimizing comfort and operating costs year-round.
Why do so many Fulton AC systems have problems with the condensate line freezing?
The typical Fulton Village Center home was built around 1978, making its original HVAC system nearly 50 years old. Age causes refrigerant levels to drop and airflow to deteriorate, creating conditions where the evaporator coil runs too cold. When this cold coil meets our area's humid air, condensate forms and can freeze within the drain line, leading to blockages and potential water damage.
