Frequently Asked Questions
Why do older Farmington homes often have frozen AC coils?
The average HVAC system in a 1981 Farmington home is now 45 years old. Over decades, minor refrigerant leaks and airflow restrictions become common, especially in the original galvanized steel ductwork. A low refrigerant charge or a dirty evaporator coil can cause the coil's temperature to drop below freezing, trapping moisture and forming ice that blocks airflow entirely.
My Ecobee thermostat shows an E1 alert. What does this mean for my system?
An Ecobee E1 error indicates the thermostat isn't detecting power from your HVAC system's control board. In Farmington, this is frequently caused by a safety switch tripping due to a frozen evaporator coil or a failed condensate pump. It signals the system has shut down to prevent damage, and a technician should check the primary drain line and refrigerant charge.
Can my existing ductwork handle a high-efficiency air filter for pollen and fine particulates?
Your home's galvanized steel ducts are generally robust, but adding a high-MERV filter requires a static pressure check. A MERV-13 filter, ideal for May pollen peaks and fine particulate matter, can restrict airflow if the system isn't balanced. We measure static pressure to ensure your blower motor can handle the upgrade without causing the evaporator coil to freeze.
Is an air conditioner's 87°F design temp sufficient for our Wisconsin summers?
Yes, an 87°F design temperature is engineered to maintain comfort during most summer days. On the handful of days where temperatures exceed this, the system will run longer to compensate. Modern units using R-454B refrigerant maintain better efficiency and capacity at higher ambient temperatures compared to older R-410A systems, providing more resilient cooling during peak heat.
How do the new 2026 SEER2 standards and rebates affect my upgrade cost?
Federal law now mandates a minimum 13.4 SEER2 for new installations. While this increases the base equipment cost, the Inflation Reduction Act provides a rebate of up to $8,000 for qualified high-efficiency heat pump installations. Combined with Focus on Energy incentives, these can offset a significant portion of the upgrade, reducing your payback period despite the $0.15/kWh utility rate.
What should I know about permits and the new refrigerant for a 2026 HVAC replacement?
All replacements require a permit from the Washington County Building Inspection Department. Since January 2023, new residential systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards for installation, including leak detection and service access, which your contractor must follow and the inspector will verify.
What's the fastest way to get emergency HVAC service near Farmington Town Center?
For a no-cool emergency, a local technician can typically dispatch from near the Farmington Town Hall. Using WI-144, the travel time to most Town Center addresses is under 10 minutes. The priority is to check for a tripped breaker or a frozen evaporator coil, which are common immediate causes we can often resolve on the first visit.
When does it make sense to switch from propane heat to a heat pump in Farmington?
Given Farmington's cold winters and your propane heat, a dual-fuel system is often the optimal solution. The heat pump handles heating during milder weather and all cooling, while the propane furnace provides efficient heat during peak cold snaps below 20°F. Scheduling the heat pump to reduce usage during utility peak hours (2 PM to 7 PM) further manages operating costs.
