INFINITY HVAC CORP.

Infinity HVAC Corp. operates out of Boston, Massachusetts with a perfect 5.0-star average across 9 verified customer reviews. The contractor specializes in design, installation, repair, and maintenance for both residential and light commercial clients. Service areas include Boston proper, Saugus, and Medford, where the team handles heating systems, ventilation, and air conditioning with a flat-rate pricing model and a 100% satisfaction guarantee. Craig, the primary technician, carries out most service calls and has built a loyal client base across these communities over what appears to be multiple years of operation.

What distinguishes Infinity HVAC Corp. from many competitors is its commitment to transparent flat-rate pricing rather than hourly billing, a model that protects homeowners from open-ended costs. The company website explicitly promises 100% satisfaction guaranteed, meaning the technician returns to resolve any issue that does not meet the customer's expectations without additional charges. All service personnel are described as highly trained experts, and Craig in particular is repeatedly called knowledgeable in reviews for his diagnostic accuracy across multiple system types, from rooftop commercial units to ductless mini splits.

Customer reviews reveal a pattern of rapid response that homeowners find invaluable. When Sang Nguyen's salon in Saugus faced a cooling failure during a heat wave, Craig arrived on the rooftop the same day within hours of the initial phone call and had the system running again before evening. TMcN experienced a furnace failure on a Sunday afternoon and Craig arrived within one hour, diagnosed the problem quickly, and completed the repair at a reasonable cost. In a separate case involving ductless mini split repair in Medford, a competing contractor had recommended a full $25,000 replacement, but Craig diagnosed the issue and had the existing system operational for a small fraction of that estimate.
