For a home built around 1984, the original HVAC system is now about 42 years old, which is well beyond its typical service life. In Croton's moderate humidity, older systems are prone to developing frozen evaporator coils. This happens as refrigerant levels drop and airflow becomes restricted over decades, causing the coil temperature to drop below freezing and ice over. Replacing the entire system is often more cost-effective than repairing a unit of this age.

Your system is designed to maintain comfort up to a specific outdoor temperature, often 86°F in this region. When actual temperatures exceed that design limit, as they often do during summer highs, the system must run continuously and its capacity drops. Modern units using R-454B refrigerant are better at retaining efficiency in these high-temperature conditions compared to older R-22 systems, but all equipment has a performance ceiling during extreme heat.

All installations in Newaygo County require a permit from the Newaygo County Building Department, which ensures compliance with current mechanical and electrical codes. Since 2025, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates that installers hold specific EPA certifications (Section 608) for handling these refrigerants and follow strict new protocols for leak detection, system labeling, and room size calculations that differ from older R-410A standards.

Modern cold-climate heat pumps are designed to operate efficiently in temperatures well below freezing, making them a viable primary heat source. The economics depend on your propane costs versus the $0.18 per kWh electricity rate, especially if you can avoid the 2 PM to 7 PM peak hours. Combining a heat pump with the up to $8,000 federal rebate and existing ductwork can significantly reduce annual heating costs while providing efficient cooling.

Galvanized steel ductwork is generally robust, but its ability to handle a high-MERV filter depends on the system's static pressure. A standard 1-inch MERV-13 filter can often be used if the duct system is properly sized and sealed, which we can test. For Croton's May pollen peak, a MERV-13 filter is effective, but a media cabinet with a deeper filter may be recommended to avoid restricting airflow in older systems.

The current minimum efficiency standard is 13.4 SEER2, a metric that better reflects real-world performance. While a higher-SEER2 unit has a greater upfront cost, the federal Inflation Reduction Act provides rebates of up to $8,000 for qualified high-efficiency installations, which can offset much of that premium. With Consumers Energy rates at about $0.18 per kWh, upgrading from a very old system to a modern 16+ SEER2 unit can reduce your cooling costs by 20-30% annually.

For a no-cool emergency, a technician can typically be dispatched from our service area near the Croton Dam and arrive in Croton Village Center within 5 to 10 minutes via M-82. We prioritize these calls during heat events to prevent indoor temperatures from rising rapidly. Having the model and serial number of your outdoor unit ready can expedite diagnosis and parts identification upon arrival.

An Ecobee E4 alert indicates the thermostat has lost communication with your HVAC equipment. In Croton, this is commonly caused by a safety lockout on the furnace control board due to a fault, such as a flame sensor issue on your propane system or a frozen evaporator coil stopping the blower. It signals the system has shut down to prevent damage, and a technician should diagnose the root cause, as resetting the thermostat alone won't resolve the underlying equipment fault.
