Questions and Answers
What does the new 13.4 SEER2 minimum mean for my energy bills, and are there rebates?
The 2026 SEER2 standard ensures new systems are about 15% more efficient than older models. At May's average rate of $0.15 per kWh, this directly lowers cooling costs. The federal Inflation Reduction Act provides rebates up to $8,000 for qualified high-efficiency installations, which often covers the entire cost premium for a SEER2 16 or higher system, making it a net-positive upgrade.
My home's original AC system is still running. How much longer can I expect it to last in May?
Systems installed in 2006 are now 20 years old, which is beyond the typical service life. In May, units from this era are especially prone to frozen evaporator coils. This failure occurs because the 20-year-old refrigerant charge degrades and the system struggles during our extreme temperature swings from morning to afternoon, causing the coil temperature to plummet below freezing.
What are the permit and safety requirements for installing a new AC with the latest refrigerant?
All installations in Washington County require a permit from the Building Inspections Department. For systems using R-454B, a mildly flammable A2L refrigerant, 2026 codes mandate specific leak detectors, revised clearance distances, and specialized technician certification. These safety standards are non-negotiable and ensure the system is installed to the latest engineering protocols for homeowner safety.
My Ecobee thermostat is showing an E160 alert. What does this mean?
The Ecobee E160 code indicates the thermostat has lost communication with the outdoor unit. In May, this is commonly caused by a tripped high-pressure switch due to a dirty condenser coil or a refrigerant issue during a rapid temperature climb. It's a protective shutdown. A technician will check the control wiring, system charge, and coil cleanliness to resolve the fault and restore communication.
Why does my AC seem to struggle on days below 95°F when it's rated for 88°F?
Air conditioners are sized for the 88°F design temperature, which is the local historical extreme they are engineered to handle. On days approaching 95°F, which exceed this design limit, any system will run continuously and may not maintain the desired indoor temperature. Modern units using R-454B refrigerant maintain better efficiency and capacity in this elevated heat range compared to older R-410A systems.
With May's pollen peaks and particulate matter, can my existing ducts handle a better air filter?
Upgrading to a MERV-13 filter is recommended to capture pollen and fine particulates. However, your home's galvanized steel ductwork must be assessed for static pressure. Older duct systems can be restrictive; adding a high-MERV filter without verifying airflow can reduce cooling capacity and increase energy use. A technician should perform a static pressure test before making the change.
I use natural gas heat. Is a heat pump a practical primary system for May winters?
Modern cold-climate heat pumps are effective in May, operating efficiently at temperatures well below our winter lows. To maximize savings, pair the heat pump with your existing gas furnace as a dual-fuel system. This setup uses the heat pump during off-peak hours and cheaper electricity, then automatically switches to gas during the utility's peak period from 2 PM to 8 PM or during extreme cold for optimal cost and comfort.
My AC stopped on a hot day in May Township Center. How fast can a technician get here?
A technician can typically be dispatched from our office near the May Township Hall within the hour. Using MN-95, we can reach most homes in the Township Center in 15 to 25 minutes for an emergency no-cool call. We prioritize these dispatches to prevent further system stress and potential water damage from a thawing coil.
