M&B has worked Charleston since 1964, from an office at 1906 Belgrade Ave, and holds South Carolina licence #105453.

Technicians are NATE-certified and factory-trained, and the company sponsors continuing education so crews stay current with newer equipment. Its stated position is that all lead technicians carry NATE certification rather than a designated few — worth confirming when you book, since the distinction between a certified lead and whoever is dispatched is where most HVAC service complaints originate.

Coverage extends past the peninsula to Mount Pleasant, James Island, North Charleston, Summerville and Kiawah Island.

Maintenance is packaged as the Cool Club, a plan structure bundling seasonal tune-ups with priority handling. Beyond conventional heating and cooling, the company installs and services geothermal systems, and its indoor air quality work covers air purification, dehumidifiers, high-efficiency filtration and duct cleaning. The dehumidification piece matters considerably more in the Lowcountry than it does in most markets.

One current issue the company addresses head-on is the refrigerant transition. Older refrigerants are being phased out in favour of lower-impact alternatives, which affects both system efficiency and what another repair on an ageing unit is actually worth. M&B offers guidance on when a system should be moved to a compliant replacement instead.

System evaluations for repair or replacement are provided at no charge, and the company runs seasonal coupons and specials alongside financing. Work sits behind a Five Star Performance Guarantee and a Peace of Mind Guarantee.

After-hours service is available for breakdowns, and the company states that callers reach a live technician who can assess severity rather than an answering service taking a message.
