Frequently Asked Questions

Can we upgrade our air filter to help with pollen and wildfire smoke?

Addressing May pollen peaks and wildfire PM2.5 requires a MERV-13 or higher filter. Your existing galvanized sheet metal ductwork with external fiberglass wrap generally provides a robust envelope for such upgrades. However, a technician must measure the system's static pressure before installation. Adding a high-MERV filter to an aging blower motor can cause airflow restriction and reduce system performance if not properly assessed.

Our home's HVAC system is original. What's the biggest risk we face?

The average home age in Fitzwilliam Village points to HVAC units approaching 48 years old. Systems of this vintage are far beyond their design life, making components like compressors and capacitors prone to failure. This age, combined with our humid continental climate, specifically leads to frozen evaporator coils. The extreme winter cycling causes moisture to accumulate and freeze on the coil, a failure point exacerbated by aging refrigerant circuits and insulation breakdown.

We use propane heat. Should we consider a heat pump?

Switching from propane to a cold-climate heat pump is a strong financial consideration for Fitzwilliam homes. Modern units effectively extract heat from outdoor air down to -15°F, covering most of our winter lows. To maximize savings, pair the heat pump with a smart thermostat to avoid operation during Eversource's peak rate hours from 2 PM to 7 PM. The combination of federal rebates and high propane costs makes this transition increasingly practical.

What are the permit requirements for a new HVAC installation?

All new installations in Fitzwilliam require a permit from the Town of Fitzwilliam Building and Code Enforcement office. As of 2026, this includes compliance with updated safety standards for A2L refrigerants like R-454B, which are mildly flammable. The permit process verifies that the installing contractor follows strict guidelines for leak detection, ventilation, and equipment labeling. This ensures the system's safety and its compliance with state and federal energy codes.

Is it worth replacing our old AC unit with a more efficient one right now?

The 2026 federal mandate requires new systems to meet a minimum 14.3 SEER2 rating. Upgrading from a unit below 10 SEER to a modern 16+ SEER2 system directly counters Fitzwilliam's 24-cent per kWh utility rate. The active Inflation Reduction Act rebates, capped at $8,000 through HEEHRA, substantially lower the upfront cost. This combination of higher efficiency and financial incentives makes replacement a sound investment.

Our heat just stopped on a cold night. How quickly can a technician get here?

For a no-heat emergency near Fitzwilliam Town Hall, dispatch from NH-119 allows a technician to be on-site within 5-10 minutes. The first step is to check your thermostat settings and the circuit breaker for the indoor air handler. If those are correct, a rapid response is critical to prevent frozen pipes. Our local routing ensures we bypass typical traffic delays to reach your neighborhood promptly.

Why does our AC struggle on the hottest summer days?

Fitzwilliam's summer highs can exceed 90°F, but standard residential systems are engineered for an 85°F design temperature. This 5+ degree gap means your unit must run continuously at peak capacity to maintain temperature, reducing its effective cooling ability. Modern systems using R-454B refrigerant offer slightly improved high-temperature performance compared to older R-22 units, but proper sizing through a Manual J load calculation remains the primary solution for comfort.

Our Ecobee thermostat is showing an E1 alert. What does that mean?

An Ecobee E1 alert indicates a communication failure between the thermostat and the outdoor HVAC unit. In Fitzwilliam, this often points to a tripped high-pressure switch or a low-voltage wiring issue exacerbated by temperature swings. This specific signal is a predictive fault; it means the system has likely entered a safety lockout. Addressing it promptly prevents a complete system shutdown during a peak cooling or heating period.
