A standard central AC replacement in New Hampshire — air handler and outdoor condenser — takes 4–8 hours for a two-person crew. Installations requiring new refrigerant lines, new electrical service, or significant ductwork modifications may take 1–2 full days. Permitting timelines in different New Hampshire jurisdictions can vary; we handle all permits as part of our installation service.

In New Hampshire, the most frequent HVAC calls involve capacitor failures (especially after high-demand summer periods), refrigerant leaks from aging copper coils, clogged condensate drain lines that cause water damage, dirty condenser coils from dust and cottonwood seeds, and furnace ignitor failures heading into winter. Routine annual maintenance prevents the majority of these issues.

No. Under EPA Section 608 regulations, purchasing and handling refrigerants like R-410A in quantities over two pounds requires an EPA technician certification. It is illegal for uncertified individuals to purchase these refrigerants. Additionally, adding refrigerant without first locating and repairing the leak is both wasteful and a violation of EPA regulations.
