Common Questions
What if my AC quits on the hottest day in Union Village?
We treat no-cool calls as critical during heat waves. Our technicians are based near Union Township Hall, allowing us to use M-217 for quick access throughout the area. You can typically expect a service van at your door within 5-10 minutes of your call to begin diagnosis and restore cooling.
My Ecobee thermostat shows an E1 alert. What's wrong?
An Ecobee E1 alert indicates a communication failure between the thermostat and your HVAC equipment. In Union, this is often caused by a low-voltage wire issue in the aging wiring of a mid-century home or a safety lockout from a recent freeze-up event. This signal means the system is inoperable until a technician diagnoses the root cause, which is typically a quick fix once identified.
Why do older Union homes have more springtime AC problems?
The average Union home was built in 1949, making many original HVAC systems over 75 years old. This age means the refrigerant charge and electrical components have degraded, lowering system resilience. This wear makes units particularly vulnerable to freeze-ups of the outdoor evaporator coils during our late spring frosts, as the system struggles to manage the rapid temperature swings.
What are the permit and safety rules for a new AC install?
All new installations in Union Township require a permit from the Cass County Building Department. Since 2025, systems using A2L refrigerants like the now-standard R-454B must follow strict 2026 safety codes for leak detection and ventilation due to the refrigerant's mild flammability. Only EPA-certified technicians holding the new A2L-specific certification can legally handle these units.
How do the new 2026 efficiency standards affect my utility bill?
Federal law now requires a minimum 13.8 SEER2 for new units, a significant jump from older standards. Pairing a high-SEER2 system with the active Inflation Reduction Act rebates, which offer up to $8,000, can offset the upfront cost. With local utility rates at $0.16/kWh, the annual savings from a modern system will be noticeable on your Indiana Michigan Power bill.
Is 88°F really a hot enough design temperature for Union summers?
The 88°F design temperature is the outdoor condition your system is engineered to maintain 70°F indoors. Summer highs here can exceed this, meaning your AC will run continuously on the hottest days to try and hold temperature. Modern systems using R-454B refrigerant are more efficient at shedding this excess heat than older R-410A units, providing more stable cooling during peak loads.
Should I switch from propane heat to a heat pump in Union?
For many homes, a cold-climate heat pump is a viable alternative to propane, especially with current rebates. The technology performs well in our winter lows, and you can use the propane furnace as a backup for extreme cold. To maximize savings, program the system to avoid peak electricity rates from 14:00 to 19:00, when Indiana Michigan Power demand charges are highest.
Can my old ductwork handle better air filters for pollen and ozone?
Union's May pollen peak and summer ozone risk make advanced filtration valuable. Your existing galvanized steel ductwork is typically robust, but installing a MERV-13 filter requires a static pressure check. An undersized duct system or a restrictive filter can choke airflow, so a technician must verify your system can handle the upgrade without losing performance.
