Questions and Answers
Can my older home's ducts handle a better air filter for ozone and pollen?
Your existing galvanized steel ductwork likely has the structural integrity for upgraded filtration. However, installing a high-MERV filter, like a MERV-13 for capturing May pollen and particulate, requires a static pressure check. An undersized or restricted duct system can cause airflow problems; a technician should measure static pressure to ensure your blower motor can handle the increased resistance without losing efficiency or comfort.
My Millersburg home's AC is from the 1990s; should I be worried about its age?
A system installed in the 1990s is now over 30 years old, which is beyond its expected service life. In our humid climate, older units with worn compressors and undersized coils are prone to condensate line freezing, a common failure point. This age also correlates with efficiency ratings well below the current 14.3 SEER2 minimum and a high likelihood of using phased-out R-22 refrigerant, making repairs costly and environmentally unsound.
How does our summer heat affect AC performance and the new refrigerants?
Millersburg's summer highs can exceed the standard 88°F design temperature the system is sized for, reducing its capacity and efficiency. The new industry-standard R-454B refrigerant operates effectively in these conditions, offering similar performance to older refrigerants but with a much lower global warming potential. Proper sizing via a Manual J load calculation is critical to ensure the system can manage the real-world temperature delta and maintain humidity control.
Is the new 14.3 SEER2 efficiency standard worth the investment with current electric rates?
Yes, the 2026 SEER2 minimum of 14.3 represents a significant efficiency jump from older units. At PPL's rate of $0.16 per kWh, a modern system can reduce your cooling costs by 30-40%. The federal HEEHRA rebate, offering up to $8,000 for qualified heat pump installations, directly offsets the higher upfront cost, improving the payback period and long-term savings for Millersburg homeowners.
If my AC fails on a hot day in Downtown Millersburg, how fast can I get help?
A technician can typically be at your home within 5 to 10 minutes. Our dispatch uses PA-147 for quick access from Market Square to the surrounding neighborhoods. For a 'No-Cool' emergency, the first steps are checking the thermostat, circuit breaker, and air filter, which a technician can verify immediately upon arrival to restore cooling swiftly.
What are the permit and safety rules for installing a new AC with the new refrigerant?
All HVAC replacements in Millersburg require a permit from the Borough Building Code Official. Since 2025, systems using A2L refrigerants like R-454B, which are mildly flammable, must follow updated 2026 safety standards. This includes specific clearance requirements, leak detectors, and updated labeling. Only EPA-certified technicians handling A2Ls can perform the installation to ensure it meets both local code and the latest refrigerant safety protocols.
With gas heat and high electric rates, does a heat pump make sense here?
A modern cold-climate heat pump is a viable option, especially with the available $8,000 rebate. While our winter lows test a heat pump's efficiency, newer models maintain heating capacity down to 5°F. To manage PPL's peak rates from 2 PM to 7 PM, a properly sized system with a compatible thermostat for load shifting is recommended. This transition can provide efficient year-round comfort from a single system.
My Ecobee thermostat is showing an E1 alert; what does that mean for my system?
An Ecobee E1 alert indicates the thermostat is not detecting a signal from your HVAC equipment, often due to a safety lockout or power issue. In Millersburg, this commonly points to a tripped high-pressure switch from a dirty condenser coil, a refrigerant issue, or a condensate line overflow switch triggering. It's a protective signal to prevent compressor damage, and a technician should diagnose the specific fault at the unit itself.
