Yes, that indicates the system was likely sized for an 85°F design temperature, a common historical standard. Sister Bay now experiences summer days in the 90s, exceeding that design limit. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures. Proper sizing with a current Manual J load calculation is critical to ensure the new unit can handle the full cooling season, not just the average conditions.

Addressing Door County's May pollen peak and seasonal ozone risk requires a MERV-13 filter, which captures fine particulates. Your home's existing galvanized sheet metal ductwork is robust, but adding a high-MERV filter can create excessive static pressure if the system isn't balanced. A technician should measure static pressure and likely recommend a 4- or 5-inch media filter cabinet, which provides superior filtration with less airflow restriction than a standard one-inch filter.

An Ecobee E1 error indicates the thermostat is not detecting power from your HVAC equipment's control circuit. In Sister Bay, this commonly points to a safety lockout on a aging furnace, a tripped float switch due to a clogged condensate drain, or a failed transformer. First, check your home's main electrical panel and the furnace's power switch. If those are on, the issue requires a technician to diagnose the specific fault in the system's low-voltage wiring or safety controls.

Yes. All installations using A2L refrigerants like R-454B, now the standard, require a permit from the Village of Sister Bay Building Department. The 2026 codes mandate specific safety measures, including leak detectors, revised service clearances, and specialized technician certification. These protocols ensure the safe handling of mildly flammable refrigerants. A reputable contractor will manage this permitting process and provide documentation of compliance for your records.

A no-cool call is a priority. From our service center, a technician can be on WI-42 and to your location in Downtown Sister Bay within 5 to 10 minutes. The first diagnostic steps involve checking for a tripped breaker, a dirty air filter restricting airflow, or an external unit blocked by debris—common issues that can be resolved quickly on-site.

The 13.4 SEER2 standard, effective in 2026, ensures new equipment is significantly more efficient than most units installed in the 1990s. At Sister Bay's average rate of $0.16 per kWh, upgrading from an 8 SEER system to a 16 SEER2 unit can cut cooling costs by nearly half. The federal Inflation Reduction Act provides income-qualified rebates up to $8,000, which can make a high-efficiency heat pump system cost-competitive with a standard replacement.

Modern cold-climate heat pumps are engineered to provide efficient heat at temperatures well below freezing, making them viable for most Sister Bay winters. The economics are compelling: during the afternoon peak rate period from 2 PM to 7 PM, using the heat pump is typically cheaper than burning propane. A hybrid system, which uses a heat pump as the primary heat source and your propane furnace as backup during extreme cold snaps, maximizes comfort and fuel savings year-round.

A 35-year-old system is well beyond its expected service life. In Sister Bay, the galvanized sheet metal ductwork in these homes often develops leaks over decades, reducing airflow to the indoor coil. This low airflow is the primary reason we see frozen evaporator coils, as the system cannot absorb enough heat. Continuing to operate it risks a catastrophic failure, like a cracked heat exchanger, which is a safety concern.
