KMG Mechanical specializes in professional mini split installation for homes and small businesses across New Hampshire and Southern Maine. Mini split systems are an energy efficient solution for heating and cooling, offering year round comfort with some models reaching efficiency ratings over 20 SEER and heating capabilities down to -13°F. These ductless systems are sleek, compact, and whisper-quiet, making them ideal for bedrooms, offices, finished basements, additions, or any space where traditional ductwork isn’t practical. With zoned temperature control, you can heat or cool specific rooms independently, improving comfort and reducing energy waste. Whether you're looking to upgrade an older system or add climate control to a new space, KMG Mechanical provides clean, expert mini split installations built for long-term performance and savings.
