M&B Heating and Air Conditioning, LLC

M&B Heating and Air Conditioning, LLC operates from Noblesville and serves Hamilton County including Carmel, Fishers, and Westfield. The company holds proper Indiana HVAC licensing and maintains a 3.5-star rating across 13 verified customer reviews. This two-person operation, led by Mark and Marlon, handles residential furnace, AC, and heat pump installations and repairs throughout the area. The contractor accepts.home warranty claims and works directly with insurance providers on covered repairs.

Multiple five-star reviewers highlight the company's honest diagnostic approach. One customer noted the technicians recommended only truly necessary repairs rather than pushing expensive upgrades, a stark contrast to competitors who quoted $4,320 for a repair this contractor resolved differently. The team also assists homeowners navigating home warranty claim paperwork, with Marlon specifically advocating for customers when disputes arise with warranty companies. Technicians take time to educate homeowners on how their systems operate rather than delivering sales pitches.

Customer reviews name specific technicians and scenarios. Alan Morales called on a Sunday evening and received a same-day Monday response with on-site diagnosis that afternoon. Shawn Grimes sought a second opinion after a major competitor quoted an expensive replacement, finding Mark provided a different assessment. Though one negative review cites scheduling and communication problems during a 2023 appointment, the company's defenders consistently mention Marlon and Mark by name, praising transparency and genuine customer advocacy during difficult warranty situations.
