Question Answers

My air conditioning stopped on a hot day near the Town Hall. How fast can a technician get here?

For a no-cool emergency, our dispatch uses NH-125 as the primary artery. From our local service hub, a technician can reach any home in Plaistow Center, including near the Town Hall, within 5 to 10 minutes. This rapid response is critical to prevent secondary damage from a frozen coil or a failed compressor.

Why is my older Plaistow system freezing up in the spring?

The average home age in Plaistow Center indicates a system likely installed around 1998, making it 28 years old. At this age, refrigerant charge can degrade, and components like the metering device wear. This often leads to a restricted refrigerant flow, a primary cause of frozen evaporator coils, especially during the moderate-humidity shoulder seasons when the system cycles on and off more frequently.

What are the permit and safety rules for a new R-454B system installation?

All installations in Plaistow require a permit from the Town of Plaistow Building Department. As of 2026, R-454B is an A2L mildly flammable refrigerant, mandating strict new safety standards. These include specific leak detection sensors, revised clearance requirements for equipment, and specialized technician certification (EPA 608 Type II or III), all of which the permit process will verify for compliance.

Does switching from propane heat to a heat pump make sense for Plaistow winters?

Modern cold-climate heat pumps are effective in New Hampshire winters. The economics are compelling when you factor volatile propane prices against a known kWh rate. To maximize savings, the system should be programmed to avoid the utility peak hours of 2 PM to 7 PM. The NHSaves rebate of up to $2,000 further improves the financial case for this transition.

Can my existing galvanized steel ducts handle better air filters for pollen and smoke?

Galvanized steel ductwork generally has a robust structure, but its age and design dictate the upgrade path. While it can physically support a MERV-13 filter for Plaistow's May pollen peak and wood smoke particulates, you must have the static pressure measured. An older blower motor may not overcome the added resistance without a costly drop in airflow and efficiency.

My Ecobee thermostat is showing an E1 alert. What does this mean for my system?

An Ecobee E1 alert signals the thermostat is not detecting a call for cooling or heating from your equipment. In Plaistow, this commonly points to a safety lockout on the control board due to a recent fault, like a high-pressure switch trip from a dirty condenser coil or a low charge. It's a diagnostic signal urging a professional check before a minor issue becomes a complete failure.

Is the new 14.3 SEER2 minimum worth the investment with current electric rates?

Yes, especially with available incentives. While the 2026 federal SEER2 minimum is 14.3, modern heat pumps easily reach 18 SEER2 or higher. At Plaistow's 24 cents per kWh, the operational savings are significant. The active Inflation Reduction Act rebates, with an $8,000 cap, can directly offset 30% or more of the project cost, improving the payback period dramatically.

How does a modern AC handle our summer heat compared to older units?

Older units were designed for an 87°F outdoor temperature, but local highs now regularly exceed that. Modern systems with R-454B refrigerant maintain a higher capacity and efficiency in these extended heat periods. The key is a proper Manual J load calculation to ensure the new system's tonnage, often around 2.5 tons here, is correctly sized for the actual heat gain, not just the old design temp.
