Frequently Asked Questions
My Ecobee thermostat is showing an E160 error code. What does this mean?
An Ecobee E160 alert specifically indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In our climate, this often points to a failed control board, a blown low-voltage fuse, or a disconnected wire in the air handler. It's a diagnostic signal that prevents the system from starting, requiring a technician to trace the 24-volt control circuit to find the break.
What are the new 2026 efficiency rules, and do the new rebates make an upgrade worthwhile?
Federal law now mandates a minimum 13.4 SEER2 for new central air conditioners. Upgrading from a unit below this standard to a high-efficiency model significantly reduces electricity use against NIPSCO's $0.15/kWh rate. The Inflation Reduction Act's HEEHRA rebates, offering up to $8,000 for qualifying heat pump installations, can dramatically offset the upfront cost, making high-efficiency upgrades financially accessible.
With gas heat, is switching to a heat pump a good idea for our Indiana winters?
A modern cold-climate heat pump is effective for Calumet Township winters, which see lows around 15°F. The technology provides efficient heating down to those temperatures. To maximize savings, pair the heat pump with a smart thermostat to avoid running it during NIPSCO's peak rate hours from 2 PM to 7 PM. The substantial federal rebates make this transition from gas more economical than in previous years.
My AC in Glen Park is over 20 years old and works poorly. What typically fails first on these systems?
A system from a 1961 home is roughly 65 years old, which is well beyond its expected lifespan. The galvanized steel ductwork and original components face cumulative stress from Calumet Township's humid continental climate. The most common failures are condensate line freezing from low airflow and blower motor wear-out. These age-related issues lead to inefficient cooling and potential water damage.
Can my home's old duct system handle better air filters for our ozone and pollen problems?
Ozone risk and the May pollen peak make advanced filtration desirable. Your existing galvanized steel ductwork is robust, but installing a high-MERV filter like a MERV-13 can create excessive static pressure if the system wasn't designed for it. A technician should measure static pressure to confirm your blower motor can handle the added resistance without reducing airflow or causing premature failure.
What are the local rules for installing a new AC with the latest refrigerant?
All installations in Calumet Township require a permit from the Calumet Township Building Department. As of 2026, new systems use mildly flammable A2L refrigerants like R-454B. Permit inspections will verify compliance with updated safety standards, which mandate special leak detectors, revised clearance distances, and specific service practices. Only EPA-certified technicians handling A2L refrigerants should perform this work.
If my AC fails on the hottest day, how quickly can a technician reach my home in Glen Park?
A no-cool emergency during a heatwave requires a fast response. From a central dispatch point near Marquette Park, a service van can take I-65 to reach most Glen Park addresses. This routing typically allows a technician to be on-site within 15 to 20 minutes of the call to diagnose the failure and begin repairs.
Why does my AC struggle when the temperature goes above 95°F?
HVAC systems in Calumet Township are designed for a 89°F outdoor temperature. When actual temperatures exceed this design limit, as they often do, the system's capacity drops and it runs continuously to try and maintain setpoint. Modern units using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-22 systems, reducing the performance gap on the hottest days.
