Claim This BusinessLong Heating & Air Conditioning Inc. has served Greenville and the surrounding Upstate South Carolina region for more than two decades, earning a reputation built on consistent service and transparent pricing. The company holds a 4.7-star rating across more than 2,200 customer reviews, reflecting a track record of showing up on time and standing behind completed work. Based at 1321-4 E. Washington Street in the Greenville area, the contractor handles residential heating and cooling needs for homeowners throughout the Upstate, including communities beyond the city limits of Greenville itself. This scale of operation does not come from aggressive marketing but from referral-based growth and repeat service agreements.
What distinguishes Long Heating from competitors comes down to how their technicians approach each call. Multiple recent reviews highlight Zach, a field technician who takes time to explain problems and solutions in plain language before recommending replacement or repair. The office staff, including Brandi, coordinates service calls and provides accurate cost estimates before work begins. Reviewers consistently note that Long Heating provided competitive bids that undercut competitor proposals, in some cases by thousands of dollars, without sacrificing the quality of installation or the brands they install. This combination of technical competence and fair pricing appears across reviews mentioning new system installations, emergency repairs, and annual maintenance plans.
The customer stories reveal why Long Heating has earned such strong referral volume. Jim Prince described a years-long problem with an oversized kitchen that other contractors could not resolve, where Long's crew diagnosed the issue, modified ductwork, and delivered the temperature control that previous companies had failed to achieve. Susan Oren noted Zach arrived during her family's 11-year relationship with the company, taking the same care to explain options as technicians had for more than a decade. Ivie K described a technician who placed booties before entering her home, a small detail that reflects company culture. These scenarios appear in reviews filed over the past year, suggesting consistent execution.
Every reviewer across this sample awarded a 5-star rating, with the three most recent customers specifically naming Zach as their technician. Four reviewers explicitly mention competitive or below-competitor pricing on new system installations, while two reviews cite successful diagnosis of problems that previous contractors could not resolve. Six of six reviewers mention professional conduct, timeliness, or both.
