Your existing galvanized sheet metal ducts can physically accept a MERV-13 filter, but their age and design may create static pressure issues. A high-MERV filter during May pollen peaks or wildfire PM2.5 events can restrict airflow in an older system. We recommend a static pressure test before installation; often, a properly sized, multi-stage air handler paired with a sealed media cabinet is needed to achieve clean air without straining the blower motor.

The 2026 federal SEER2 mandate raises the minimum efficiency standard. For Edmonds homes, a modern 16-18 SEER2 heat pump operating at our $0.11 per kWh rate will use significantly less energy than a unit from the 1990s. The active Inflation Reduction Act rebates, with an $8,000 cap, can directly offset the cost of a high-efficiency upgrade, making the long-term operational savings immediate.

A typical 1973-built home in Edmonds would have an original HVAC system over 20 years old. The galvanized sheet metal ductwork with fiberglass wrap is durable but lacks modern sealed insulation. The moderate humidity profile of the region creates ideal conditions for algae growth in the condensate pan and drain line. This age-related wear on drainage components is the primary cause of the common condensate drain blockage we see here.

Edmonds HVAC systems are engineered for an 85°F design temperature, balancing efficiency and capacity. When ambient temperatures exceed this, the system's delta T (temperature drop) decreases, reducing its ability to remove heat. The newer standard R-454B refrigerant maintains better pressure and cooling capacity at these higher temperatures compared to older R-410A, but any system will run longer and work harder during a heat spike above its design limit.

An Ecobee E1 alert indicates the thermostat has lost communication with your heat pump's outdoor unit. In Edmonds, this is often caused by a condensate drain blockage triggering an internal safety float switch, which cuts power to the outdoor unit. It can also signal a tripped circuit breaker or a failed low-voltage wire connection, issues exacerbated by our damp environment. This alert allows for proactive service before a complete system failure occurs.

Yes, the transition is highly efficient for our climate. A cold-climate heat pump provides effective heating down to our winter lows, moving multiple units of heat for every unit of electricity used, unlike resistance heat. To maximize savings, program the thermostat to avoid pre-heating during Snohomish PUD's peak hours (7-10 AM and 5-8 PM). This shift leverages our mild winters and low electric rates for substantial cost reduction.

All new installations using R-454B, an A2L mildly flammable refrigerant, require a permit from the City of Edmonds Building Division. The 2026 safety standards mandate specific leak detection systems, revised clearance distances, and specialized technician certification. These codes ensure the safe integration of this new refrigerant class into your home's mechanical space, and the permitting process verifies compliance with these updated protocols.

A technician can typically be dispatched within 15-20 minutes. Our service routing from the Edmonds Ferry Terminal area uses I-5 to quickly reach most downtown neighborhoods. We prioritize no-cool calls, especially during our warmer design days, to prevent indoor temperature and humidity from rising rapidly in your home.
