Galvanized steel ductwork is generally robust, but adding a MERV-13 filter requires a static pressure check. While the duct material can handle it, the system's blower must overcome the added resistance. In May, during peak pollen, a MERV-13 is ideal, but an undersized or aging blower may struggle, potentially reducing airflow and cooling capacity.

The 87°F design temp is the point at which the system is sized to maintain 75°F indoors. On hotter days, it will run continuously to keep up, and indoor temps may rise slightly. The newer R-454B refrigerant in these systems maintains stable pressure and efficiency better than older refrigerants under these extended high-load conditions common in our summers.

All installations in Juneau County require a permit from the Zoning and Sanitation Department. For the R-454B refrigerant, which is a mildly flammable A2L, 2026 codes mandate specific leak detection systems, revised clearance requirements, and specialized technician certification. These protocols ensure the safe integration of this new standard refrigerant into your home.

A no-cool call during peak hours is treated as a priority. From our dispatch near the Elroy Commons, we can typically reach any home in the City Center via WI-80 within 5 to 10 minutes. We keep parts for common failures, like contactors and capacitors, on the truck to facilitate a same-day repair when possible.

A system from a 1954 home is likely past its design lifespan, meaning components like the evaporator coil are fatigued. In our humid continental climate, restricted airflow from clogged filters or failing blower motors is common, causing the coil to drop below freezing and ice over. The age of the galvanized steel ductwork can also contribute to airflow imbalances that lead to this specific failure.

An Ecobee E1 code indicates the thermostat is not detecting a call for cooling or heat from your HVAC equipment. In Elroy, this often points to a failed control board, a blown low-voltage fuse, or a safety switch—like a float switch—being tripped due to a clogged condensate line. It's a signal that the system has shut down to prevent damage and requires professional diagnosis.

Modern cold-climate heat pumps are effective in our region, operating efficiently in temperatures well below freezing. The economics are compelling when you factor in high propane costs and the ability to use the unit for efficient summer cooling. Programming it to avoid the 2 PM to 7 PM utility peak hours can maximize savings, making the transition from propane a sound long-term investment.

The 13.4 SEER2 mandate ensures new units use significantly less electricity than older models. At Elroy's average rate of $0.16 per kWh, a properly sized 2.5-ton SEER2 system can save hundreds annually. The federal HEEHRA rebate, active with an $8,000 cap, often covers a major portion of the upgrade cost when paired with the local Focus on Energy incentive of $500.
