A unit installed in 1984 is now 42 years old, well beyond its expected service life. In Campton’s humid climate, this age makes two failure points highly probable. First, the repeated freeze-thaw cycles stress the heat exchanger, leading to fatigue and potential cracks. Second, the original galvanized condensate lines are prone to rust and blockage, which can cause water damage. Proactive replacement is advised over reactive repair at this stage.

Managing May pollen peaks and winter particulate matter requires effective filtration, often MERV-13. Your existing galvanized sheet metal ducts with fiberglass wrap are generally robust and can accommodate higher MERV filters, but a static pressure test is necessary first. An older blower motor may struggle with the increased resistance, potentially reducing airflow and causing the system to overheat. We recommend a professional assessment before upgrading filters.

An 85°F design temperature means the system is sized to maintain a 75°F indoor temperature when it's 85°F outside. On hotter days, which are common, the system will run continuously to try to meet the thermostat setpoint, potentially falling short. Modern systems using the new R-454B refrigerant maintain better efficiency and capacity at these elevated temperatures compared to older R-22 units, reducing the performance gap on the hottest afternoons.

All HVAC replacements in Campton require a permit from the Campton Building Department, which ensures compliance with state building and mechanical codes. As of 2026, new equipment predominantly uses A2L refrigerants like R-454B, which are mildly flammable. This mandates adherence to updated safety standards, including specific leak detection and room size requirements that your contractor must follow. Proper permitting also validates your system for eligibility under the Inflation Reduction Act rebate programs.

A complete loss of cooling requires immediate diagnosis to prevent compressor damage. From our service hub near Campton Town Hall, we dispatch technicians via I-93 for direct access to the Village, typically within 5 to 10 minutes. This rapid response is critical during heat waves to secure your home and begin troubleshooting common issues like a tripped breaker or a frozen coil before they escalate.

The SEER2 14.3 minimum, effective in 2026, is a measure of seasonal energy efficiency under updated testing standards. For a home using the Campton average of 2.5 tons of cooling, upgrading from an old 10 SEER unit to a new 18 SEER2 model can save approximately 600 kWh annually at the local rate of $0.24 per kWh. The federal Inflation Reduction Act rebate of up to $8,000 directly offsets the cost of qualifying high-efficiency heat pump systems, improving the payback period.

Modern cold-climate heat pumps are engineered to provide efficient heat down to near 0°F, covering most of Campton's winter. The economics are compelling: while propane costs fluctuate, electricity at $0.24/kWh can provide heat at a lower cost per BTU, especially when avoiding the 5-9 PM peak utility rates. Combining this with the up to $8,000 federal rebate and NHSaves incentives makes the transition from propane to a dual-fuel or full heat pump system a strategic upgrade for year-round comfort and cost control.

An Ecobee E1 error code signals a communication failure between the thermostat and the HVAC equipment. In Campton, this often points to a specific sequence: a frozen condensate line from high humidity can trigger a safety float switch, which then cuts power to the control board and breaks communication. First, check for water around the indoor air handler. This alert prevents system operation to avoid water damage, so addressing the condensate drain blockage is the primary repair step.
