In the heart of Montgomery Village – Gaithersburg, Rockville, and Olney, MD stands a symbol of the enduring spirit of service – Mannix Heating & Cooling. Our company’s foundation was built not on the bricks of any physical structure, but on the values of trustworthiness, excellence, and relentless dedication to our community’s comfort needs.

Serving the heart of Maryland and Virginia

Transitioning into Chantilly, Centreville, and Dulles, VA, our influence grew, not just as an HVAC repair service but also as an imperative member of the community. Every heating repair task, each HVAC service provided, and installations of air conditioning systems we’ve performed, have not been mere services rendered but a testament to the commitment that Mannix bears for its community.

Going beyond just AC and Furnace Services

At Mannix, we see ourselves as more than just a cooling and heating service provider. We are a team of handpicked specialists, each committed to delivering the promise of exceptional comfort cusped with superior customer care. To every home in Montgomery, Gaithersburg, and beyond, we thank you for becoming a part of our story, centred on keeping you well equipped to face every season with smiles and warmth.
