Your galvanized sheet metal ductwork with fiberglass wrap is generally robust and can often support a MERV-13 filter, which captures PM2.5 from wildfire smoke and pollen. However, installing one in an older system requires a static pressure check. If the blower motor is original, the added resistance may reduce airflow and cause the evaporator coil to freeze, so a professional assessment is advised.

Your system was designed for an 84°F outdoor temperature, which is the local design temp for sizing calculations. On days reaching the low 90s, the unit operates at its capacity limit, reducing its ability to remove heat and maintain your setpoint. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A units.

All installations require a permit from the Town of Johnson Zoning and Building Department. As of 2026, new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety standards, including specific leak detection and ventilation requirements. Your installer must be EPA Section 608 certified for A2Ls to handle the refrigerant legally and safely.

An Ecobee E1 alert indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Johnson, this often points to a safety lockout on the control board due to a prior fault, like a frozen coil or pressure switch issue. It requires a technician to diagnose the root cause, which is frequently related to the age of the system and its components.

For a home built around 1973, your original HVAC system is over 50 years old. Ice damming on the outdoor unit and frozen condensate lines are common age-related failures. The system's efficiency has degraded, and components like the metering device or blower motor may not be operating to original specifications. This leads to improper refrigerant flow and reduced heat transfer, which causes ice to form during operation.

SEER2 is the updated 2026 efficiency metric; the federal minimum is now 14.3 SEER2. With Johnson's electricity rate at $0.19 per kWh, upgrading from an old unit to a high-efficiency model, like an 18 SEER2 heat pump, yields significant savings. The Inflation Reduction Act rebate, with an $8,000 cap, directly reduces the upfront cost, improving the payback period on your investment.

A technician can usually be at your home within 5 to 10 minutes for an emergency no-cool call. Our service area is centralized around Downtown Johnson, with VT-15 providing direct access from our office near Johnson State College. We prioritize these calls to prevent further strain on aging systems and restore comfort promptly.

Yes, modern cold-climate heat pumps are designed for Vermont winters and operate efficiently in sub-zero temperatures. Pairing one with your existing propane furnace as a backup creates a dual-fuel system that optimizes cost. Running the heat pump during off-peak hours, outside of the 5 PM to 9 PM window, leverages lower electricity rates and maximizes savings versus propane.
