Q&A
Our Ecobee thermostat is showing an 'E1' alert. What does that mean here?
An Ecobee E1 error indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Northville, this often points to a safety lockout from a clogged condensate drain line—the pan is full and the float switch has opened. It can also signal a failed control board or a blown low-voltage fuse, commonly from a short in the wiring to the outdoor unit.
What are the rules for installing a new AC or heat pump now?
All installations in LaSalle County require a permit from the Building and Zoning Department. Since 2025, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards for installation, including leak detectors, revised service practices, and updated equipment markings that a qualified technician will handle.
Our HVAC unit is from when the house was built. What should we expect?
A system installed with a 1982 home is now 44 years old. At this age, the galvanized steel ductwork and original components are far beyond their expected service life. In Northville's humid climate, the condensate drain line is particularly prone to blockage from algae growth, which is the most common failure point for systems of this vintage. This age also indicates a high likelihood of refrigerant leaks and failing electrical components.
How well should our AC handle our actual summer heat?
Northville's design temperature for cooling is 89°F, meaning systems are sized to maintain comfort at that outdoor temperature. On days exceeding that, which occur regularly, capacity drops and indoor temperature may rise. Modern units using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A systems.
We have gas heat. Should we consider a heat pump in Northville?
A cold-climate heat pump is a viable primary system for our region. Its efficiency during ComEd's peak hours (2 PM to 7 PM) can lower operating costs compared to standard AC. For the few deepest winter nights, the system may use integrated electric resistance backup. The key is a proper Manual J load calculation to ensure the unit is sized for both our summer design temp and winter heating needs.
What if our AC stops working on the hottest day of the year?
For a no-cool emergency in Downtown Northville, a technician can typically dispatch from near the Northville Public Library and use IL-34 for quick access to most neighborhoods. Our average response time is 5-10 minutes. The first step is always to check the condensate drain pan for overflow, a frequent cause of safety switch trips, and to ensure the furnace filter is not completely blocked.
Can we use a better air filter for our allergies and the summer ozone?
Upgrading filtration helps capture May pollen peaks and mitigate ozone-related particulate. However, installing a high-MERV filter in older galvanized steel ducts requires a static pressure check. These rigid ducts often have higher friction loss, and a MERV-13 filter can restrict airflow enough to cause freezing or overheating if the system isn't balanced for it.
Is it worth replacing our old AC just to meet the new efficiency rules?
The federal minimum standard is now 13.8 SEER2. Modern systems often reach 16-18 SEER2, offering significant savings over Northville's 0.15/kWh electricity rate. The Inflation Reduction Act provides rebates of up to $8,000 for qualifying high-efficiency heat pump installations, which can dramatically offset the upgrade cost and improve your home's overall energy profile.
