KEN's HVAC SERVICE

Ken's HVAC Service operates from 28 College Road in Waltham, serving the Greater Boston metro including Arlington and surrounding communities. The owner-operated company handles heating, air conditioning, and refrigeration work for both homes and commercial properties, offering installation, repair, and preventive maintenance across all equipment brands. With five verified five-star reviews and no negative feedback, the team has built a solid reputation for residential HVAC work in the area.

The company offers a $99 Furnace Maintenance Special that includes a full system inspection, cleaning, and performance check. This promotion reflects a practical approach to preventive care, aligning with their stated recommendation for biannual tune-ups before summer and winter seasons. Their smart-home offerings include Nest thermostat installation, with documented experience resolving common obstacles like missing C-wire connections that often complicate thermostat upgrades.

During a 100-degree-plus heat wave, Ken arrived the same day when other contractors ignored calls, communicating an arrival time and honoring it. Another reviewer recounts how Ken diagnosed a furnace condensation problem that multiple previous technicians failed to solve, recommending targeted repairs rather than the thousands in parts replacements others had suggested. Technician George handled line-set insulation replacement on a mini-split system, using a higher-grade product than the disintegrating foam that had been installed originally.
