Callahan A/C & Heating Services

Callahan AC & Heating keeps homes comfortable across North Andover and the New Hampshire Lakes Region from their Belmont Street headquarters. With 42 verified reviews contributing to a 4.2-star average, this contractor has built a steady presence in Essex County and southern New Hampshire. The company handles cooling, heating, and plumbing systems for residential and light commercial clients, operating Monday through Friday with standard business hours.

What distinguishes Callahan from regional competitors is their financing flexibility and Mitsubishi heat pump specialization. Homeowners can pursue free estimates and explore service agreements that bundle annual maintenance, while rebate programs help offset equipment costs. Their documented experience with variable-speed heat pump installations and ductwork retrofitting addresses a growing market for high-efficiency upgrades in older New England housing stock.

Reviewers describe two distinct service experiences worth noting. One customer reported a two-day Mitsubishi heat pump installation with whole-home ductwork, praising competitive pricing and clean worksite conditions after crawlspace insulation work. Another long-term client emphasized on-time, on-budget project delivery alongside courteous responsiveness during urgent situations. However, a 2023 service call resulted in a basement flood from an unplugged condensate pump, and the customer reported repeated attempts to reach the company went unresolved for months.
