Common Questions
How well does a new AC handle our hottest summer days?
Erie's design temperature for cooling is 86°F, but actual highs can exceed this. A properly sized system, based on a Manual J load calculation, is engineered to maintain temperature at the design limit. The new standard R-454B refrigerant operates efficiently in this range. Oversizing a unit to chase peak temperatures leads to short cycling, poor humidity control, and reduced equipment life.
Why does my old air conditioner keep freezing up?
The average HVAC system in Erie is about 41 years old. At this age, refrigerant charge often drops due to slow leaks in the original galvanized steel linesets, lowering coil pressure. A system with low refrigerant pressure experiences a sharp drop in temperature at the evaporator coil, which causes condensation to freeze. This is a common failure progression for equipment installed when your home was built.
What if my heat goes out tonight near City Hall?
A no-heat call after hours is a priority dispatch. From our service center off US-2, we can be at any home in Downtown Erie within 5 to 10 minutes, including those near Erie City Hall. We carry common natural gas furnace ignitors and pressure switches on our trucks to resolve many emergency failures on the first visit.
Can my current ducts handle a better air filter for smoke and pollen?
Erie's May pollen peak and summer wildfire smoke PM2.5 risk make filtration critical. Your existing galvanized steel ductwork is generally robust, but installing a standard 1-inch MERV-13 filter can create excessive static pressure in older systems. A proper assessment measures airflow to determine if a deeper 4-inch media cabinet is needed to achieve high filtration without straining the blower motor.
Should I switch from my natural gas furnace to a heat pump?
For Erie's climate, a cold-climate heat pump paired with your existing gas furnace as a backup is a strategic hybrid approach. You would use the efficient heat pump during milder weather and off-peak hours, avoiding the 2 PM to 7 PM utility peak. The gas system provides reliable heat during extreme cold snaps below the heat pump's optimal operating range, ensuring comfort and managing operating costs.
My Ecobee thermostat is showing an E4 alert. What's wrong?
An Ecobee E4 code specifically indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Erie, this often points to a safety lockout on the control board, a failed low-voltage transformer, or a blown fuse in the furnace. It's a signal that the thermostat is functional, but the system it commands is not responding, requiring technician diagnostics.
What are the rules for installing a new AC with the new refrigerant?
All installations using A2L refrigerants like R-454B, now the standard, require permits and inspections through the Erie Building and Safety Department. As of 2026, national and local codes mandate specific safety measures for these mildly flammable refrigerants, including leak detectors, revised clearance distances, and specialized technician certification. Proper permitting ensures your system meets these updated safety standards.
Is the new SEER2 rating worth the upgrade cost?
The federal minimum efficiency standard is now 13.4 SEER2 for northern regions like ours. While your current electric rate is $0.14/kWh, a modern 16+ SEER2 unit can cut cooling costs by over 20%. The Inflation Reduction Act's HEEHRA rebates, active with an $8,000 cap, can offset a major portion of the upgrade, making the payback period for Erie homeowners surprisingly short.
