Frequently Asked Questions
What are the permit and safety rules for a new AC installation?
All new installations in Assumption require a permit from the Christian County Building and Zoning Department. Since 2025, systems using A2L refrigerants like R-454B must follow updated safety standards. These include specific leak detection requirements, revised clearance distances, and the use of certified, flame-resistant materials. A licensed contractor will handle this permitting process to ensure code compliance.
Can my old ducts handle a better air filter for pollen and ozone?
May brings a pollen peak and summer ozone is a local air quality hazard, making filtration important. Your existing galvanized steel ductwork may have restrictive fittings. Installing a MERV-13 filter without a static pressure test can starve the blower of air. A technician should measure your system's static pressure to confirm it can handle higher filtration without losing airflow or efficiency.
Should I consider a heat pump with natural gas so cheap?
While natural gas is a primary heat fuel, modern cold-climate heat pumps operate efficiently in Assumption's winter lows. Pairing a heat pump with your existing gas furnace as a dual-fuel system can optimize costs. Using the heat pump during off-peak hours and switching to gas during the utility peak period from 2 PM to 7 PM can maximize savings and provide reliable comfort year-round.
Why does my old HVAC unit keep getting clogged?
The average home in Assumption was built around 1955, so original HVAC systems are over 70 years old. This age causes galvanized steel drain pans to corrode, creating a rough surface that traps algae and sludge. Combined with the region's high humidity, this leads to frequent condensate drain line clogs, a primary failure point for vintage systems.
My Ecobee thermostat shows an E1 error. What does that mean?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Assumption, this is commonly caused by a safety float switch being triggered due to a clogged condensate drain line—a frequent issue in our humid climate. It can also signal a control board fault or a blown low-voltage fuse, protecting the system from water damage.
What should I do if my AC stops on a hot day?
First, check your thermostat settings and the circuit breaker. If there's no cool air, a technician from the Central Assumption area can typically be at your home within 5-10 minutes. We dispatch from near the Assumption Public Library and use US-51 to reach most local calls quickly, allowing for a same-day diagnosis of common issues like a tripped float switch or failed capacitor.
Is the new 13.4 SEER2 standard worth the upgrade cost?
The 13.4 SEER2 minimum for 2026 represents a significant efficiency gain over older units. With Ameren Illinois rates at $0.14/kWh, the operational savings are tangible. The federal HEEHRA rebates, capped at $8,000, can dramatically offset the upfront cost for a qualifying high-efficiency system, making the upgrade a financially sound long-term investment for Assumption homeowners.
Why does my AC struggle on the hottest days of the year?
Assumption's design temperature for AC is 89°F, but summer highs often exceed this. When outdoor temperatures climb above the design limit, the system's capacity drops and it must run continuously to maintain temperature. Modern units using R-454B refrigerant are engineered for better performance in these high-ambient conditions compared to older R-22 systems, maintaining a more stable delta T.
