FAQs
My furnace seems to be running constantly. How old are most heating systems in Franklin?
A home built in 1958 likely has a furnace or boiler that is 20+ years old, as most systems are replaced once in a home's lifetime. This age aligns with galvanized steel ductwork common in Franklin. Older systems are prone to salt-related coil corrosion from winter road treatments and frozen condensate lines due to inefficient dehumidification, leading to constant runtime and higher oil consumption.
With May pollen and PM2.5 risk, can my old ductwork handle a better air filter?
Addressing PM2.5 and pollen requires a MERV-13 filter, but your existing galvanized steel ducts may create high static pressure if undersized or leaky. A technician should measure static pressure before installation; often, sealing duct leaks at the boots and plenum is necessary to allow a high-efficiency filter without straining the blower motor or reducing airflow.
My Ecobee thermostat is showing an E4 alert. What does that mean here?
An Ecobee E4 alert specifically indicates a loss of communication with your heat pump's outdoor unit. In Franklin, this is often caused by a tripped high-pressure switch from a dirty coil, a refrigerant issue, or a failed control board. It's a critical signal to prevent compressor damage, and the system will typically lock out until a technician diagnoses the fault.
What are the rules for installing a new AC or heat pump in Franklin now?
All installations require a permit from the City of Franklin Building and Zoning Department. As of 2026, new systems using A2L refrigerants like R-454B must comply with updated safety standards (UL 60335-2-40). These include leak detectors, specific circuit breaker requirements, and room size calculations performed by a certified technician, ensuring safe handling of mildly flammable refrigerants.
Why does my AC struggle on the hottest days when it's only 87°F outside?
The 87°F design temperature is an engineering standard for sizing, but Franklin regularly experiences days in the 90s. At these higher temperatures, the system's capacity drops and the delta T (temperature split) can shrink. Modern units using R-454B refrigerant maintain better efficiency and capacity at these elevated ambient temperatures compared to older R-410A systems.
My air conditioner just stopped on a hot day near Odell Park. How fast can a technician get here?
For a 'No-Cool' emergency in Downtown Franklin, dispatch from a service center near I-93 allows a technician to reach your home near Odell Park in 5-10 minutes. The priority is to check for a tripped breaker, a clogged condensate drain causing a safety switch, or a frozen coil, which are common quick-resolve issues during our humid summers.
What's the new efficiency standard, and do rebates make an upgrade worthwhile with our electric rates?
Federal law now mandates a minimum of 14.3 SEER2 for new central air conditioners and heat pumps. With Franklin's electric rate of $0.24 per kWh, upgrading from a 10 SEER unit to an 18 SEER2 model can cut cooling costs by nearly half. The active Inflation Reduction Act rebate via NH Saves offers up to $8,000, which often covers the majority of the upgrade cost when paired with a high-efficiency heat pump.
I use heating oil. Should I consider a heat pump for my Franklin home?
Given Franklin's winter lows and peak utility hours from 17:00 to 20:00, a dual-fuel system pairing a heat pump with your existing oil furnace is strategic. The heat pump handles moderate heating efficiently, saving oil, while the furnace provides reliable heat during extreme cold and peak electric rate periods. This hybrid approach maximizes comfort and cost-effectiveness.
