Frequently Asked Questions
Why does my air conditioner struggle when it gets above 95 degrees?
Harrison's HVAC systems are engineered to a 89°F design temperature, meaning they maintain comfort efficiently up to that point. Summer highs exceeding 95°F create a capacity gap, as the unit must work harder for diminishing returns. Modern systems using R-454B refrigerant maintain better performance and pressure in these high-heat conditions compared to older R-410A units.
What are the permit and safety requirements for a new AC installation in 2026?
All new installations in Harrison require a permit from the Harrison Building and Zoning Department. As of 2026, systems using A2L refrigerants like R-454B must comply with updated safety standards (UL 60335-2-40). This mandates leak detectors, revised clearance zones, and specific labeling. Only EPA Section 608 certified technicians with A2L-specific training can legally handle this equipment.
My air conditioner is from the 1990s. What should I expect with a system that old here?
A unit from the 1990s is now 28-36 years old, exceeding its typical lifespan. In Harrison's humid climate, the primary failure point for systems of this age is condensate drain line clogs. The internal pan and PVC lines degrade over decades, leading to algae and mold growth that blocks drainage. This often results in water damage and system shutdowns before the compressor itself fails.
Is switching from my gas furnace to a heat pump a practical choice for our Indiana winters?
Modern cold-climate heat pumps are effective in Harrison's winters, operating efficiently at temperatures well below freezing. The economic case is strengthened by the $8,000 federal rebate and Duke Energy's $400 incentive. To maximize savings, schedule heavy electrical use outside the 2 PM to 7 PM peak rate window, letting the heat pump's thermal storage effect work in your favor.
Can my home's existing ductwork support better air filters for ozone and pollen?
Harrison's ozone risk and May pollen peak make MERV-13 filtration desirable. Your existing galvanized steel ductwork is typically robust, but adding a high-MERV filter can create excessive static pressure in an older system not designed for it. A technician should measure static pressure and may recommend upgrading to a media cabinet or a dedicated air purifier to avoid straining the blower motor.
If my air conditioner stops working on a hot day in Downtown Harrison, how fast can a technician arrive?
For a no-cool emergency, dispatch from our office near the Harrison Community Center provides access to I-74, allowing a technician to reach most Downtown Harrison homes within 5 to 10 minutes. We prioritize these calls to prevent heat buildup and humidity damage, especially during peak cooling hours.
My Ecobee thermostat is showing an 'E1' alert. What does that mean?
An Ecobee E1 alert signals the thermostat has lost communication with your HVAC equipment. In Harrison, this is commonly caused by a safety switch trip from a clogged condensate drain line, a frequent issue in our humid climate. It can also indicate a blown low-voltage fuse or a failing control board. This alert allows for proactive service before a complete system failure occurs.
What does the new 14.3 SEER2 minimum efficiency standard mean for my energy bill?
The 14.3 SEER2 mandate, effective January 2023, ensures new systems use at least 15% less energy than previous 13 SEER units. With Duke Energy Indiana rates at $0.14/kWh, this translates to tangible savings. Pairing a high-efficiency system with the active Inflation Reduction Act heat pump rebate, capped at $8,000, significantly improves the return on investment.
