Get answers to common questions about hvac services in Farmington, New Hampshire.
For a standard single-family home in Farmington, a full AC replacement typically ranges from $5,000 to $12,000. This cost is influenced by the system's size (tonnage), efficiency rating (SEER), and the complexity of the installation, such as ductwork modifications. Given our humid summers and the need for reliable cooling, investing in a properly sized, energy-efficient unit (16+ SEER) is recommended for long-term comfort and operational savings.
The ideal time is during the shoulder seasons—late spring or early fall—before the peak demand of winter. Scheduling service in September or October ensures your system is ready for Farmington's cold, snowy winters and helps you avoid the high-volume service delays common during the first deep freeze. This timing also provides more flexibility for scheduling and potential installation discounts from local HVAC companies.
While Farmington follows the State of New Hampshire building codes, there are no unique local town ordinances for standard HVAC replacements. However, homeowners should always check that their contractor pulls the required state mechanical permit. Importantly, you should explore rebates from New Hampshire's electric and gas utilities (like Eversource or Unitil) and federal tax credits for high-efficiency equipment, which can significantly offset upgrade costs.
Look for a licensed, insured, and locally established contractor with strong references from within Strafford County. Verify they carry a New Hampshire Mechanical License. A reputable provider will perform a detailed Manual J load calculation specific to your home's construction and Farmington's climate to correctly size equipment, rather than simply matching the old system's size. Checking reviews and their responsiveness for emergency winter service is also crucial.
Yes, this is a common concern. Standard air-source heat pumps lose efficiency as temperatures drop below freezing, which occurs frequently in Farmington winters. For optimal year-round performance, homeowners have two excellent options: installing a newer cold-climate heat pump (ccHP) model specifically designed for New England winters or keeping a properly maintained fossil fuel or electric furnace as a dual-fuel/hybrid system to provide backup heat during extreme cold spells.
