Q&A
What are the rules for installing a new AC with the modern refrigerant?
All installations using A2L refrigerants like R-454B, which is now standard, require a permit from the Brown Township Building Department. As of 2026, federal EPA rules mandate specific safety standards for these mildly flammable refrigerants, including leak detectors, updated service ports, and specialized technician certification. Proper permitting ensures the installation meets these updated codes for safety and performance.
Our furnace is from 1997. Is it on borrowed time?
A 1997 furnace is 29 years old, which is beyond its expected service life. In Brown Township, this age means critical components like the heat exchanger are under stress from decades of thermal cycling. Galvanized steel ductwork from that era can also develop leaks, reducing system efficiency. This advanced age is a primary reason why these systems are prone to condensate drain line clogs, as the PVC trap and drain pan materials degrade over time.
Our 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 your HVAC equipment. In Brown Township, this often points to a safety lockout on the furnace control board, frequently triggered by a clogged condensate drain line—a prevalent issue in our humid climate. It can also signal a failed flame sensor on your gas furnace or a tripped high-pressure switch on the AC.
We have gas heat. Should we consider a heat pump for our Brown Township home?
For Brown Township, 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 sub-freezing lows and avoids high electrical consumption during AES Indiana's 2-7 PM peak rate period. This setup maximizes comfort and operational cost savings.
Why does our AC struggle when it hits 95°F, even though it's rated for 90°F?
Air conditioners are sized for a 90°F design temperature, which is the local engineering standard. On a 95°F day, the system operates beyond its design capacity, losing about 1-3% of its rated cooling ability per degree above that point. Modern units using R-454B refrigerant maintain better performance in this extreme heat due to its superior thermodynamic properties compared to older R-410A.
Can our home's duct system handle a high-grade filter for ozone and pollen?
Your existing galvanized steel and fiberglass duct board system likely has adequate integrity. However, installing a MERV-13 filter requires a static pressure check. In our humid continental climate with a May pollen peak, a MERV-13 is excellent for particulates, but it can restrict airflow in an older system not designed for it, potentially causing the furnace to overheat or the AC to freeze.
Our AC just quit on a hot day in Brownsburg Core. How fast can you get here?
We dispatch from near Arbuckle Acres Park. Using I-74, we maintain a 15-20 minute response time to Brownsburg Core for no-cool emergencies. A technician will first check for a tripped breaker or a clogged condensate safety switch, common quick fixes. If the issue is deeper, like a failed capacitor, we carry common parts on our trucks for immediate repair.
Is the new 14.3 SEER2 minimum worth the investment with current electricity prices?
The 2026 federal 14.3 SEER2 minimum is a significant efficiency jump. With AES Indiana rates at $0.14/kWh, a new 16-18 SEER2 system can cut cooling costs by roughly 20-30% compared to a 20-year-old unit. The active Inflation Reduction Act rebates, with caps up to $8,000, directly offset this higher upfront cost, improving the payback period for homeowners in Brown Township.
