FAQs
My Ecobee thermostat is showing an 'E1' alert. What does that mean here?
An Ecobee E1 error indicates the thermostat is not detecting a call for cooling or heating from the HVAC equipment. In Clay Township, this often points to a safety lockout on the control board due to a persistent issue like a clogged condensate drain—a common failure in humid climates. It signals the system has shut down to prevent water damage, requiring a technician to clear the drain and reset the lockout.
My air conditioner stopped on a hot day near Clay Terrace. How fast can a technician arrive?
A dispatch from our service center near US-31 places a technician in the Carmel-Clay Residential District within 15-20 minutes. We route around the shopping traffic at Clay Terrace to ensure a prompt response for no-cool emergencies, which are critical during peak heat to prevent compressor damage.
What does the new 14.3 SEER2 minimum mean for my electricity bill?
The 2026 SEER2 standard ensures new systems are about 10% more efficient than previous models. At AES Indiana's rate of $0.14 per kWh, this directly lowers cooling costs. The federal HEEHRA rebate, offering up to $8,000 for income-qualified households, can offset the upfront cost of a high-SEER2 unit, accelerating the payback period.
Why does my AC struggle when it gets above 90 degrees?
HVAC systems in Clay Township are sized for a 89°F design temperature based on historical data. When ambient temperatures exceed this, the system runs continuously to try to meet the setpoint, reducing its capacity. Modern units using R-454B refrigerant maintain better efficiency and pressure stability in this extended heat compared to older R-410A systems.
Can my home's ductwork handle a high-efficiency air filter for pollen and ozone?
Galvanized sheet metal ductwork typically has the structural integrity to handle a MERV-13 filter, which captures pollen during its May peak and mitigates ozone byproducts. However, installing one in an older system requires a static pressure check. An unbalanced system can reduce airflow and strain the blower motor, negating the air quality benefits.
My HVAC unit is from the late 80s. Is it time for a replacement?
Systems from the 1980s are now 38 years old, well past their 15-20 year design life. Age degrades electrical components and increases corrosion in the galvanized sheet metal ductwork common in Carmel-Clay. This corrosion contributes to sediment that frequently causes condensate drain line clogs, a primary failure point for aging units in Clay Township's humid climate.
What are the permit and safety rules for a new AC installation now?
All installations in Clay Township require a permit from the Clay Township Building Department. As of 2026, new units use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety standards (UL 60335-2-40), including leak detection sensors and specific circuit breaker requirements, which must be verified by the inspector for the permit to be finalized.
Should I consider switching from my gas furnace to a heat pump?
For Carmel-Clay homes, a cold-climate heat pump is a viable primary heat source. It operates efficiently in our winter lows and shifts energy use from gas to electricity. To maximize savings, pair it with a thermostat that avoids operation during AES Indiana's peak hours (2 PM to 7 PM), when rates are highest, and utilize the available utility and federal rebates for the switch.
