Michigan summer highs can exceed 95°F, but residential systems in Gerrish are typically designed for a 85°F outdoor temperature. When it's hotter than the design temp, the system cannot maintain the usual 20°F delta T and will run continuously to try and cope. Modern units using R-454B refrigerant maintain better efficiency and capacity in these high ambient temperatures compared to older refrigerants.

A unit in a Gerrish home built around 1981 is now about 45 years old, which is well beyond its expected service life. Systems this age are prone to frozen evaporator coils because their original airflow designs often can't handle our moderate indoor humidity. The galvanized sheet metal ductwork can develop internal rust or debris over decades, further restricting airflow and causing the coil to ice over. This is a common failure point signaling the need for a full system assessment.

For homes using propane heat, a cold-climate heat pump is a strong financial option. Modern units provide efficient heating down to around 5°F, covering most of our winter. Pairing it with a smart thermostat to avoid operation during Consumers Energy's 14:00-19:00 peak rate hours maximizes savings. The existing IRA rebates make the switch even more compelling by reducing the upfront cost of a qualifying system.

The 2026 federal minimum is 13.4 SEER2, a new testing standard that better reflects real-world performance with your ductwork. While a basic 13.4 SEER2 unit meets code, upgrading to a 16-18 SEER2 model yields significant savings at Gerrish's $0.18/kWh rate. The active Inflation Reduction Act rebates, with caps up to $8,000, can offset much of the premium for a high-efficiency unit, improving the payback period.

Your existing galvanized sheet metal ducts with external wrap are generally robust, but installing a high-MERV filter requires a static pressure check. A MERV-13 filter is excellent for trapping May pollen and wood smoke particulates common here, but it can restrict airflow in an older system. We measure static pressure to ensure the new filter won't cause the evaporator coil to freeze or reduce system capacity.

An Ecobee E4 code indicates the thermostat isn't detecting power from your HVAC system's control circuit. In Gerrish, this often points to a safety switch being triggered, commonly from a clogged condensate drain line due to our humidity or a tripped float switch. It can also signal a failed control board or transformer. The first step is to check and clear the drain line, located near the indoor air handler, before resetting the system.

All installations in Roscommon County require a permit from the Roscommon County Building Department. Since 2025, new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety standards, including specific leak detection, room size calculations, and clear labeling. Only EPA-certified technicians holding the new A2L specialty certification can legally handle and install this equipment.

A dispatch from our shop near Houghton Lake State Forest Area allows for a 10-15 minute response to Gerrish Township Center via US-127. For a no-cool call, we first check for simple issues like a tripped circuit breaker or a clogged filter causing a frozen coil. If the system uses an older R-22 refrigerant, a major leak may mean a repair isn't feasible, but we can diagnose that on-site quickly to give you clear options.
