Frequently Asked Questions
What are the permit and safety requirements for installing a new AC unit with the new refrigerant?
All new installations in Monroe County require a permit from the Monroe County Building Department. Since 2025, most new equipment uses A2L refrigerants like R-454B, which are mildly flammable. 2026 codes mandate specific safety standards for these installations, including leak detection systems, revised clearance distances, and specialized technician certification (EPA 608 Type II or III). Proper permitting ensures the installation meets these updated safety and efficiency codes for your home's protection.
With ozone alerts and May pollen, can my older ductwork handle a better air filter?
Addressing ozone and pollen requires a filter with a MERV-13 rating or higher. Your home's original galvanized sheet metal ductwork is generally robust, but adding a dense filter can create excessive static pressure if the system wasn't designed for it. This can reduce airflow and strain the blower motor. A technician should perform a static pressure test before installing high-MERV filters to ensure your system can handle the increased resistance without losing performance.
Why does my AC struggle on the hottest days when it's only 89 degrees out?
Your system is designed to maintain temperature up to its 89°F outdoor design temperature, a standard for our region. On days that exceed this, its capacity diminishes. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-22 units. However, consistent operation above the design limit indicates the system may be undersized for the current heat load or requires maintenance to restore peak performance.
My Ecobee thermostat is showing an 'E1' alert. What does this mean for my HVAC system?
An Ecobee E1 alert indicates the thermostat has lost communication with the HVAC equipment. In La Salle, this is often not a thermostat failure but a symptom of a system safeguard tripping. The most common cause is a condensate line blockage, which activates the safety float switch and cuts power to the control circuit. Check the condensate drain line and drain pan for water first. If clear, the issue may be a tripped circuit breaker or a failing control board, requiring professional diagnosis.
My furnace seems fine but the AC keeps shutting off. Could this be related to the age of my system?
A system installed when the home was built, around 1976, is now about 50 years old. In La Salle's humid climate, this age makes condensate line blockages a common failure point. Older drain pans and lines accumulate microbial growth and sediment over decades, which can trip the system's safety float switch and cause intermittent shutdowns. A full inspection of the condensate drainage system is typically the first diagnostic step for units of this vintage.
Our AC stopped working during dinner. How fast can a technician get to a house in La Salle Center for a no-cool emergency?
For a no-cool emergency, a technician can typically be dispatched from our service area near La Salle Township Park. Using I-75 for access, the travel time to most addresses in La Salle Center is reliably between 8 and 12 minutes. We prioritize these calls to prevent heat buildup and humidity from affecting the home's interior before diagnostics and repairs can begin.
I'm hearing about new SEER2 ratings. What does the 13.4 minimum mean for my electricity bill, and are there rebates?
The 13.4 SEER2 minimum for 2026 is a baseline for new equipment efficiency. For La Salle, with an average rate of $0.17 per kWh, upgrading from a much older unit to a modern 16+ SEER2 system can reduce cooling costs by 20-30%. The federal Inflation Reduction Act (HEEHRA) provides rebates with an $8,000 cap, which often covers a significant portion of a qualifying high-efficiency system, improving the payback period substantially.
Given our cold winters and peak electricity rates, does switching from gas heat to a heat pump make sense in La Salle?
A modern cold-climate heat pump is viable for La Salle, even with winter lows. The key is proper sizing for the heating load at our design temperature. While DTE Energy's peak rates from 2 PM to 7 PM increase operating costs, a high-efficiency heat pump's seasonal performance can still offer savings, especially when paired with the federal rebates. For maximum reliability, many homes here use a hybrid system, pairing a heat pump with the existing gas furnace as a backup for the coldest hours.
