HVAC Service & Maintenance

A high-performance, energy-efficient building always starts with an intelligent design, but just as important are well-maintained HVAC systems. Most building owners know that environmental comfort is the number one concern for building occupants. Mechanical systems also represent the highest total consumption of energy in most buildings.

Fidelity Mechanical Services has one of the largest and most sophisticated HVAC service groups that serve the Baltimore, Washington, D.C., and Northern Virginia metropolitan areas. We have three Fidelity Mechanical Services locations staffed with hundreds of factory-trained technicians and HVAC system experts. Maintaining high-performance buildings and preventing mechanical failures through proactive planned maintenance is our business.
