Q&A
My Ecobee thermostat is showing an E1 alert. What's wrong?
An Ecobee E1 error indicates a communication failure between the thermostat and your HVAC equipment. In Worth Township, this often points to a wiring issue at the indoor air handler or a failing control board, not an outdoor compressor failure. First, check for any tripped breakers. If power is confirmed, the problem is likely internal and requires a technician to diagnose the control circuit, a common service call that prevents a complete system shutdown.
My system is original to my home. Is it time to replace it?
A 1998 system is now 28 years old, which exceeds the typical lifespan for HVAC equipment in Worth Township. The primary risk for a unit of this age is evaporator coil corrosion. Our area's humid continental climate subjects the coil to significant seasonal humidity flux, accelerating the breakdown of the thin aluminum fins. This corrosion leads to refrigerant leaks, a common failure point that is often more costly to repair than replacing the entire system with a modern, efficient unit.
Can my existing ductwork handle better air filters for pollen and ozone?
Your galvanized steel and fiberglass duct board system likely has sufficient integrity for a MERV-13 filter, which effectively captures pollen during its May peak and fine particulates linked to ozone risk. The critical factor is static pressure; an older blower motor may struggle. A technician should measure the system's static pressure before installing a high-MERV filter to ensure it doesn't restrict airflow, which can lead to frozen coils and reduced comfort.
Why does my AC struggle when it's over 90 degrees?
Central Indiana's design temperature for cooling equipment is 90°F. When outdoor temperatures exceed this, the system's capacity to remove heat diminishes, and it may run continuously to maintain setpoint. Modern systems using R-454B refrigerant are engineered for better performance in these high-temperature conditions compared to older R-410A units, but all systems have a performance limit. Proper sizing from a Manual J load calculation ensures your unit is matched to your home's specific heat gain.
Should I consider switching from my gas furnace to a heat pump?
For Worth Township homes, a dual-fuel system pairing a heat pump with your existing gas furnace is often optimal. The heat pump handles moderate winter temperatures efficiently, while the gas furnace provides reliable heat during extreme lows below 20°F and avoids the high cost of electric resistance heating during AES Indiana's peak hours (2 PM to 7 PM). This setup leverages the strengths of both fuels for maximum comfort and operating cost management.
What are the rules for installing a new AC system here?
All new installations in Boone County require a permit from the Area Plan Commission. Since 2025, systems using A2L refrigerants like R-454B, which are mildly flammable, must comply with updated safety standards (UL 60335-2-40). This mandates specific leak detectors, service access, and labeling. A licensed contractor will handle the permit process and ensure the installation meets these 2026 codes for equipment clearance, electrical requirements, and refrigerant charge.
What does the new 14.3 SEER2 minimum mean for my bills?
The 2026 federal SEER2 standard mandates higher efficiency for new central air conditioners. For a typical 3-ton system, upgrading from a 12 SEER unit to a new 16 SEER2 model can reduce cooling costs by approximately 15-20%. With AES Indiana's rate at $0.147 per kWh, this represents meaningful savings. The Inflation Reduction Act's HEEHRA rebates, with an $8,000 cap, can significantly offset the initial cost of a qualifying high-efficiency system, improving the overall return on investment.
If my AC quits on a hot day, how fast can someone get here?
A technician can typically be dispatched from near Anson Park to your Whitestown home within 15 to 25 minutes via I-65. For a 'No-Cool' emergency, the first step is to check your home's breaker panel and ensure the outdoor unit is clear of debris. A quick dispatch allows for diagnosis of common issues like a tripped safety switch or a failed capacitor before the indoor temperature rises significantly.
