Your existing galvanized steel ducts with fiberglass blanket insulation have a robust structure, but adding a MERV-13 filter requires evaluation. These filters create higher static pressure that can overwhelm an older blower motor. A technician should measure the system's static pressure and potentially adjust the fan speed to ensure proper airflow without sacrificing cooling capacity or causing the evaporator coil to freeze.

Air conditioners are sized for the 89°F design temperature, which represents a local historical extreme. When ambient temperatures exceed this, as they often do, the system must run continuously and its capacity drops. The newer R-454B refrigerant in modern units maintains better pressure and efficiency in these high-heat conditions compared to the older R-410A, reducing the performance gap on the hottest days.

An Ecobee E1 alert indicates the thermostat is not detecting power from the HVAC equipment. In Crown Point, this commonly points to a tripped float switch due to a clogged condensate drain line—a frequent issue given our high humidity. It can also signal a blown low-voltage fuse on the control board, often from a failing contractor or a short in the wiring. This error proactively prevents water damage by shutting the system down.

A 35-year-old furnace is well beyond its typical 15-20 year service life. In Crown Point's humid continental climate, the original galvanized steel ductwork and fiberglass insulation are likely compromised. This age, combined with our winter freeze-thaw cycles, significantly increases the risk of condensate line freezing and failure. Corrosion and cracks in the heat exchanger are also a critical safety concern at this stage.

Modern cold-climate heat pumps are effective in our region, where winter lows typically reach 10-15°F. The economics depend on your natural gas versus electricity rate. Operating the heat pump during off-peak hours (outside 12:00-20:00) maximizes savings. A hybrid system, which uses the heat pump as the primary heater and the gas furnace as backup during extreme cold or peak pricing, often provides the best balance of comfort and cost.

For a no-cool emergency, a local technician can typically dispatch from near the Lake County Courthouse. Using I-65 for access, most service calls to the downtown area have a 5 to 10 minute travel time. We prioritize these calls to prevent heat buildup and humidity damage inside the home, especially during peak utility hours.

Confirm the contractor is EPA-certified for A2L refrigerants like R-454B, which are mildly flammable and have strict 2026 handling and leak-detection requirements. All installations require a permit from the Crown Point Building Department, which ensures code compliance for safety clearances, electrical work, and drainage. Using an unlicensed installer for an A2L system voids most warranties and creates significant liability.

The 13.8 SEER2 mandate for 2026 ensures a meaningful jump in baseline efficiency. With NIPSCO rates at $0.145/kWh, the operational savings are real. The financial decision is heavily influenced by the active HEEHRA rebates, which can provide up to $8,000 in upfront savings, making a high-efficiency system like an 18 SEER2 unit a cost-effective upgrade over merely meeting the minimum.
