Q&A
What does the new 13.4 SEER2 minimum mean for our electricity bills?
The 13.4 SEER2 mandate for 2026 sets a higher baseline for cooling efficiency. With local utility rates at $0.18 per kWh, upgrading from an old 8-10 SEER unit to a modern 16+ SEER2 system can cut cooling costs significantly. The active federal HEEHRA rebates, with caps up to $8,000, directly offset the upfront cost of these high-efficiency units, improving the payback period.
Can our older home's system handle a better air filter for pollen and ozone?
Addressing May pollen peaks and general ozone risk requires enhanced filtration, like a MERV-13 filter. Your existing galvanized sheet metal ducts are robust, but the aged blower motor may struggle with the higher static pressure a dense filter creates. A technician should measure static pressure to verify the system can handle the upgrade without reducing airflow or causing premature motor failure.
What should we know about permits and safety for a new AC installation?
All HVAC replacements in Thomas Township require a permit from the Thomas Township Building Department. As of 2026, new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety standards (UL 60335-2-40), requiring specific leak detectors, revised electrical clearances, and technician certification. Proper permitting ensures this critical safety code is met.
We use gas heat. Is switching to a heat pump a good idea here?
For homes in Shields, a dual-fuel system pairing a heat pump with your existing gas furnace can be optimal. The heat pump efficiently handles moderate winter temperatures and cooling, while the gas furnace provides reliable heat during extreme cold snaps below its balance point. This setup also shifts load away from the 2-7 PM utility peak hours during the cooling season, managing costs effectively.
How well do new air conditioners handle our hottest summer days?
Michigan's design temperature for cooling is 88°F, but actual temperatures can exceed this. Modern systems using R-454B refrigerant are engineered to maintain capacity and efficiency closer to their rated performance in these higher ambient conditions compared to older R-22 units. Proper sizing via a Manual J load calculation ensures the unit can manage the heat load without short-cycling.
Our home's original AC is still running. Is that typical for Shields?
Many homes in the Shields Residential District were built around 1976. A system from that era is now 50 years old, which is well past its expected service life. Age degrades components and increases internal corrosion. This wear makes your galvanized sheet metal ductwork and the evaporator coil's condensate drain line prone to clogging with rust and biological growth, a frequent failure point for systems of this vintage.
If our AC quits on a hot day, how quickly can a technician get here?
A complete loss of cooling demands a fast response. Our service vehicles are based near Shields Park, providing direct access to the Shields Residential District via M-52. This routing allows for a reliable 5 to 10 minute dispatch time for emergency no-cool calls, ensuring a technician is on-site promptly to diagnose and begin repairs.
Our Ecobee thermostat is showing an 'E1' alert. What does that mean?
An Ecobee E1 code signals the thermostat has lost communication with the outdoor AC unit for over 5 minutes. In Shields, this often points to a safety lockout from a clogged condensate line triggering a float switch, a tripped high-pressure switch from a dirty condenser coil, or a failed low-voltage control wire connection. It's a specific alert that prevents compressor operation to avoid damage.
