Claim This BusinessBlume Mechanical Service operates as a licensed HVAC contractor in Largo, Florida, holding license CAC-1822618 and maintaining a 4.9-star rating compiled from 140 customer reviews. The company serves Largo residents alongside Clearwater, Seminole, and surrounding Pinellas County neighborhoods. Monday through Friday, technicians respond to service calls from 7 AM to 5 PM, with Saturday availability until 1 PM. This family-operate d business model means the same skilled professionals handle diagnosis, repair, and follow-up personally.
What distinguishes Blume Mechanical Service from competitors is their designation as Bosch experts, a manufacturer partnership that allows access to specialized diagnostic tools and proprietary components. The team offers both residential and light commercial HVAC solutions, with a Giving Back program indicating community involvement. Technicians provide second opinions at no pressure, and customers report receiving honest assessments that sometimes save money rather than generate invoices. All service calls receive thorough documentation, and follow-up communication ensures systems operate as expected after repairs.
Customer reviews reveal specific scenarios demonstrating the company's approach. Chris, a named technician, performed a second-opinion evaluation for John Putnam that saved the homeowner money without attempting to upsell unnecessary parts. For Gerard Kane, Chris responded to an AC issue the next morning and followed up personally to confirm proper function. When D M needed a new air conditioner, both Tye and Chris coordinated installation around a busy schedule, delivering what the reviewer called an excellent product at an excellent price. Pam Rilling received same-day service within an hour of her call during a system breakdown.
139 of 140 reviewers award 5 stars, with the single 1-star review citing payment communication rather than technical work quality. Multiple reviews specifically name technicians Chris and Tye, describing thorough diagnostics and follow-up. Positive reviewers consistently mention honest assessments that saved money, while the sole negative review references billing disputes.
