Question Answers
My Ecobee thermostat shows an E1 error. What does that mean here?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In French Island, this is commonly caused by a safety lockout on the system itself, often triggered by a frozen evaporator coil or a faulty pressure switch. It's a signal to check the indoor air handler and outdoor unit for ice buildup or obstruction before resetting the system, as continuous operation in this state can cause compressor damage.
My system is from the 90s and still works. Should I be concerned?
A system from the 1990s is roughly 30 years old, which is double the typical service life. In French Island's climate, a core concern for units of this age is frozen evaporator coils. The original R-22 refrigerant is obsolete, and its phase-out makes repairs costly. More critically, older galvanized steel ductwork often develops small air leaks over decades, reducing efficiency and introducing humidity that can accelerate coil freezing from debris accumulation.
What are the rules for installing a new AC unit now?
All new installations in the Town of Campbell require a permit from the Building Inspection Department. As of 2026, systems using A2L refrigerants like R-454B, which are mildly flammable, must follow strict EPA Section 608 regulations for leak testing, charge limits, and required service practices. Technicians must be certified for A2L handling, and equipment must be installed per manufacturer specifications and local code for clearance and safety.
Can my home's ductwork handle better air filters for pollen and dust?
French Island faces Particulate Matter risks and a May pollen peak, making filtration important. Your existing galvanized steel ducts are robust but may not handle a restrictive MERV-13 filter without causing high static pressure. A technician should measure static pressure and may recommend sealing leaks or upgrading the blower motor to ensure proper airflow and effective filtration without damaging the system.
Is the new SEER2 rating worth the upgrade cost?
The 2026 federal minimum is 13.4 SEER2, but modern systems easily reach 16-18 SEER2. At the local utility rate of $0.15 per kWh, the higher efficiency directly reduces operating costs. The Inflation Reduction Act's HEEHRA rebates, with an $8,000 cap, can significantly offset the initial investment, making the upgrade financially sensible over the system's lifespan.
My AC stopped on a hot day. How fast can a technician get here?
For a no-cool emergency on French Island, our dispatch uses real-time traffic from I-90 and monitors air traffic at La Crosse Regional Airport to route technicians efficiently. This logistics approach typically yields a 10 to 15-minute response window. We prioritize these calls to prevent further strain on an aging system and to secure your home's interior conditions quickly.
I use gas heat. Should I consider a heat pump with our cold winters?
Modern cold-climate heat pumps are effective for French Island winters, operating efficiently at temperatures well below freezing. The economic case involves comparing your gas rates to the $0.15 per kWh electricity cost, especially during utility peak hours from 2 PM to 7 PM. Pairing a heat pump with your existing gas furnace as a dual-fuel system can optimize costs, using the heat pump as the primary heater and the furnace as backup during extreme cold or peak pricing.
Why does my AC struggle when it gets above 90 degrees?
French Island's HVAC systems are typically sized for a 88°F design temperature based on historical data. When outdoor temperatures exceed this, the system must run continuously to maintain setpoint, reducing its ability to dehumidify effectively. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older refrigerants, but proper sizing remains critical.
