Ductless mini split in Chantilly, Virginia

r been disappointed. They are always professional, reliable, and knowledgeable. The technicians are polite and take the time to explain any issues with my HVAC system. I recently had them replace my aging HVAC system and the whole process was seamless. From the initial consultation with Eric to the installation by Billy and Matt, I was impressed with the level of service and communication. Mannix Heating & Cooling truly exceeded my expectations. I highly recommend them to anyone in need of HVAC services in Gaithersburg, MD, Chantilly, VA, or the surrounding areas. Whether you need repairs, maintenance, or a new installation, Mannix Heating & Cooling is the company to call.
