Claim This BusinessConway Heating and Air holds a 5-star average across 184 verified client reviews, a record that places the contractor among the most consistently rated professionals in the greater Billerica area. Founded and operated by John Conway, a military veteran who has spent over 15 years working on residential heating and cooling systems across eastern Massachusetts, the company is fully licensed and insured, offering a straightforward guarantee of quality on every service call. Working hours run Monday through Friday from 7 a.m. to 5 p.m., and the crew responds promptly to heating or cooling failures that cannot wait until the next business day.
The distinguishing strength at Conway Heating and Air is honest, straightforward communication about what a system actually needs. Rather than recommending full replacements when repairs would suffice, technicians walk homeowners through their options and explain the reasoning behind each cost estimate. The company also handles indoor air quality improvements, including humidification, heat-recovery ventilation, air filtration, and ultraviolet anti-bacterial lighting, making it practical to bundle air duct cleaning with a new thermostat installation or a seasonal maintenance check during the same visit.
Multiple reviewers specifically named John Conway as the technician who showed up for them during genuine emergencies. When one Billerica resident woke to a broken furnace on a cold December Saturday morning and called twelve other contractors without a single response, John arrived within thirty minutes and had the system running again by the following afternoon. Another customer who lost heat on a subfreezing Sunday morning reached John by phone at 7 a.m.; he was at the house within three hours and lent portable heaters to bridge the gap until the replacement part arrived the next day. These scenarios illustrate what a consistent track record of rapid, reliable service looks like in practice.
Of the 184 reviews, at least five describe emergency same-day or after-hours callouts, with John Conway arriving in under an hour in two separate cases. No negative reviews were present in the available dataset; all reviewers award five stars and emphasize honesty, transparency, and fair pricing rather than upselling.
