Question Answers
Can we use better air filters for the ozone and pollen here?
Yes, addressing Monona's ozone risk and May pollen peak requires enhanced filtration. A MERV-13 filter is effective, but your existing galvanized steel ductwork must be assessed. Older ducts often have higher static pressure; installing a high-MERV filter without verifying airflow can strain the blower motor and reduce system efficiency.
What are the permit and safety rules for a new AC install now?
All HVAC installations in Monona require a permit from the Clayton County Building and Zoning Department. As of 2026, new systems using mildly flammable A2L refrigerants like R-454B must comply with updated UL 60335-2-40 safety standards. This mandates specific leak detectors, revised clearance zones, and proper labeling, which a certified technician will handle as part of the permitted job.
My AC just quit on a hot day in Downtown Monona. How fast can a tech arrive?
We dispatch from near Monona City Park and can monitor traffic on US Highway 52 for the fastest route. For a no-cool emergency in your neighborhood, a technician typically arrives within 5 to 10 minutes. We prioritize calls that involve loss of cooling or heating to prevent further system stress or indoor air quality issues.
Is a higher SEER2 rating worth the extra cost with our electric rates?
The 2026 federal minimum is 13.4 SEER2, but units up to 20 SEER2 are common. At Monona's rate of 14 cents per kWh, the higher efficiency directly lowers operating costs. The federal Inflation Reduction Act provides rebates with an $8,000 cap, which can offset the initial investment and improve the payback period significantly compared to a baseline unit.
We use expensive propane. Should we switch to a heat pump?
For Monona homes using propane, a cold-climate heat pump is a viable primary heat source. These systems operate efficiently in temperatures well below our winter lows. To maximize savings, pair the heat pump with a smart thermostat to avoid operation during Alliant Energy's peak hours from 2 PM to 7 PM, when electricity rates are highest.
Why does my AC struggle when it's only 95 degrees out?
Monona's HVAC systems are engineered for an 88°F design temperature. When outdoor temps exceed that, the system runs continuously to maintain setpoint, which is normal operation. Modern units using R-454B refrigerant are designed for better capacity retention in high heat compared to older R-22 systems, improving performance during these peak conditions.
Our furnace seems original. How old could it be and what's the main risk?
Homes in Monona average a 1947 build year, making many systems nearly 80 years old. A unit of that age is well beyond its expected service life. The primary failure for these old systems in our climate is frozen evaporator coils, caused by refrigerant leaks or airflow restrictions that modern units with better sensors and A2L refrigerants like R-454B are designed to prevent.
My Ecobee thermostat is showing an E4 alert. What does that mean?
An Ecobee E4 alert indicates the thermostat has lost communication with your HVAC equipment. In Monona, this often points to a safety lockout on the furnace control board or a tripped high-pressure switch, frequently triggered by issues like a dirty flame sensor on older propane systems or a refrigerant-related fault. It's a signal to call for service before a complete failure occurs.
