Get answers to common questions about hvac services in Stratham, New Hampshire.
For a full high-efficiency AC system replacement in Stratham, including installation, homeowners can expect to pay between $5,000 and $12,000. The final cost depends heavily on the home's size, the system's SEER rating, and the complexity of the ductwork. Given our humid summers and the desire for efficiency, investing in a unit with a SEER rating of 16 or higher is common to manage long-term cooling costs effectively.
The ideal schedule is biannual: have your heating system serviced in late summer or early fall (before October) and your cooling system serviced in early spring (before June). This timing ensures your furnace is ready for our cold, snowy winters and your AC is prepared for humid summer heat, avoiding the peak-season rush when local HVAC companies are busiest with emergency breakdowns.
While New Hampshire has no statewide mechanical code for residential HVAC, Stratham may have local building permit requirements for new installations, so always check with the town. Importantly, you should explore rebates from New Hampshire's electric and gas utilities, like Eversource or Unitil, which often offer significant incentives for installing high-efficiency heat pumps, a popular choice for our climate as they provide both heating and cooling.
Look for a licensed, insured, and locally-established contractor with strong references in Stratham and surrounding towns. They should be familiar with our specific climate challenges, such as preparing systems for nor'easters and humidity. Always verify they are EPA-certified for refrigerant handling and check their reviews on platforms like Google or the Better Business Bureau for consistent, quality service.
Yes, this is a common concern. Standard air-source heat pumps lose efficiency as temperatures drop below freezing, which is why they are often part of a dual-fuel or hybrid system paired with a backup furnace (like propane or oil) in our region. For optimal year-round comfort, many Stratham homeowners install cold-climate heat pump models specifically designed to operate efficiently in sub-freezing New Hampshire temperatures.
