Q&A
Can we add better air filters to help with spring allergies and summer ozone?
May pollen peaks and summer ozone risk make advanced filtration valuable. However, installing a MERV-13 filter in a 1950s-era galvanized steel duct system requires a static pressure check. Older ductwork is often restrictive, and a high-MERV filter can choke airflow, causing the furnace to overheat or the AC coil to freeze. A technician should measure static pressure first; duct sealing or modification may be necessary to handle the better filter safely.
What should we know about permits and safety for a new AC installation?
All HVAC replacements in Iroquois County require a permit from the Iroquois County Building and Zoning Department. Since 2025, new systems must use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific installer EPA certifications and safety protocols, including leak detectors and updated labeling. The permit process ensures the installation meets these 2026 safety standards, proper electrical load, and adherence to local codes, protecting your home investment.
Our furnace seems as old as our house. How long do these systems typically last in Onarga?
The average home age in Central Onarga points to original HVAC equipment being nearly 70 years old. Most furnaces and air handlers have a functional lifespan of 15-25 years. At that age, galvanized steel ductwork often develops leaks, and the entire system operates well below modern efficiency and safety standards. This advanced age also makes components like the condensate drain highly susceptible to blockage from biological growth, a common issue given our area's humidity profile.
Our Ecobee thermostat is showing an 'E1' alert. What does that mean for our system?
An Ecobee E1 error code signals the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Onarga, this often points to a safety lockout on the furnace control board or a tripped high-pressure switch on the outdoor unit, frequently triggered by a clogged condensate drain due to our high humidity. It's a diagnostic starting point, indicating the system has shut down to prevent damage and requires professional service to reset and address the root cause.
Why does my air conditioner struggle when it gets above 95 degrees?
HVAC systems in Onarga are engineered for a 89°F design temperature, balancing efficiency and cost. When ambient temperatures exceed this, the system runs continuously to maintain a temperature delta, or 'delta T'. Modern units using R-454B refrigerant maintain better capacity and efficiency in these high-load conditions compared to older R-22 systems. Proper sizing from a Manual J load calculation ensures the unit is matched to the home's actual heat gain.
We use natural gas heat now. Should we consider a heat pump with our weather?
Heat pump technology now performs effectively in our humid continental climate. During our winter lows, a cold-climate heat pump with a proper defrost cycle can provide efficient heating. Pairing it with your existing gas furnace as a dual-fuel system is optimal; the heat pump handles moderate weather and the expensive 2 PM to 7 PM peak electricity hours, while the furnace provides reliable heat during extreme cold snaps, maximizing comfort and operating cost savings.
Is it worth replacing a working but old AC unit just to get a higher SEER rating?
The 2026 federal minimum is 13.8 SEER2, but modern systems easily achieve 16-18 SEER2. At Ameren Illinois's current rate of $0.14 per kWh, upgrading from a 10 SEER unit to an 18 SEER2 model can cut cooling costs by nearly 40%. The active Inflation Reduction Act rebates, with caps up to $8,000, substantially offset the initial investment, making the payback period for Onarga homeowners surprisingly short.
If our air conditioning stops on the hottest day, how fast can a technician get here?
A dispatch from a service van near Onarga Community Park provides a reliable 5 to 10 minute response to most homes in Central Onarga. Technicians use I-57 for quick north-south access across the county. For a true no-cool emergency on a 90-degree day, the priority is restoring cooling to prevent heat stress, with diagnostics on the high-pressure switch or capacitor beginning immediately upon arrival.
