A1 / AC Heating & Cooling

A furnace, air conditioner and thermostat were all part of the installation one A1/AC customer praised in a 2018 Google review. The workers also reused the old furnace’s humidifier and fixed a basement door that had already been broken. That reviewer was pleased with both the equipment and the price. A1 / AC Heating & Cooling is based in Agawam and describes itself as locally owned and operated, serving Hampden County. Its written reviews run from 2011 to 2026. In a 2016 Angi account, a customer described Mark working alongside his crew throughout an installation, including the gas lines. The customer said Mark added three returns because the existing return was too noisy, and reported lower operating costs and no problems with the installed system. A 2017 reviewer praised clean, efficient removal and replacement of equipment, saying the new American Standard units ran more quietly than the old ones. A September 2011 Angi review described a two-day heating and air-conditioning replacement that finished as promised. The customer also had a thermostat moved and a carbon-monoxide alarm, dehumidifier and water heater installed. They said the crew removed the old equipment, cleaned the work area and handled rebate paperwork; payment was requested only after completion and the customer’s approval. In November 2021, another Angi reviewer praised Mark’s availability for questions and described a new furnace installed when they added onto their house. More recent complaints deserve attention. A June 2026 Google reviewer said A1/AC had installed a unit the previous year but repeatedly failed to return calls afterward, prompting the customer to use another company. In an April 2025 review about a 2018 winter service call, another customer said a technician replaced a thermostat in less than ten minutes and charged $181.62. The reviewer objected to receiving the bill without a quote or warning. A1/AC advertises free estimates and says it is insured. Its BBB grade is A+, and Angi lists 5.0 stars from 15 ratings.
