Questions and Answers
Can my home's original duct system handle better air filters for ozone and pollen?
Original galvanized steel ductwork in 1950s homes is generally robust but was designed for low-restriction filters. Installing a high-efficiency MERV-13 filter to capture May pollen and mitigate ozone-related particulates requires a static pressure check. An undersized duct system or a restrictive filter can choke airflow, reducing cooling capacity and potentially causing the evaporator coil to freeze.
My Ecobee thermostat is showing an 'E1' alert. What does that mean?
An Ecobee E1 code signals the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Long Lake, this commonly points to a safety lockout on the control board due to a recent fault, like a flame sensor issue on the furnace or a high-pressure switch trip on the AC. It's a diagnostic signal advising a system power cycle at the breaker before calling for service.
Should I consider switching from my natural gas furnace to a heat pump?
For Long Lake homes, a dual-fuel system pairing a heat pump with a gas furnace is often optimal. The heat pump efficiently handles moderate cooling and heating, especially during ComEd's 2 PM to 7 PM peak rate periods. During sustained temperatures below 30°F, the system automatically switches to the natural gas furnace for more economical and powerful heat, ensuring comfort and cost-effectiveness.
Why is my old central air conditioner freezing up so often?
A unit installed when the home was built in 1956 is now 70 years old. This age puts significant strain on the sealed refrigerant circuit. In Long Lake's moderately humid climate, the evaporator coil's internal fins corrode over decades, reducing surface area for heat absorption. This can cause refrigerant to not fully vaporize, leading to liquid floodback and the coil icing you're experiencing.
My AC just stopped on a hot day in Long Lake Estates. How fast can a technician get here?
For a no-cool emergency, dispatch prioritizes your area. From our service hub near the Long Lake Metra Station, we take US-12 directly into the neighborhoods. Barring unusual traffic, a technician typically arrives within the 10-15 minute window. We recommend turning the system off at the thermostat to prevent further compressor stress while you wait.
Is the new 13.8 SEER2 minimum efficiency standard worth the upgrade cost?
The 2026 SEER2 mandate reflects a 15% efficiency gain over older models. At Long Lake's current rate of $0.16 per kWh, a new 16 SEER2 system can save approximately $300 annually. The federal HEEHRA rebate, active with an $8,000 cap, directly offsets this higher initial investment, making the payback period for a qualifying homeowner significantly shorter.
What are the permit and safety rules for a new AC installation in 2026?
All replacements in the Village of Long Lake require a permit from the Building Department. Since January 2023, new residential systems must use lower-GWP A2L refrigerants like R-454B. These are mildly flammable, so 2026 code mandates specific leak detectors, updated service ports, and permanent markings on the equipment. Proper permitting ensures the installation meets these updated safety standards for your home.
How well do new air conditioners handle our summer heat above 90 degrees?
Long Lake's design temperature for cooling is 89°F. On days exceeding that, all systems lose capacity, but newer units with R-454B refrigerant maintain performance better. R-454B has a lower global warming potential and offers slightly improved heat transfer efficiency at high ambient temperatures compared to older R-410A, providing more stable cooling during peak afternoon heat.
