Quick Answers

Does Holmes Mechanical Contractors handle commercial HVAC, not just residential systems?

Holmes Mechanical Contractors focuses exclusively on government, commercial, and industrial infrastructure, with no residential work listed among its services. The firm's portfolio includes commercial chiller systems, VRF design and installation, air handler systems, hydronic and steam boilers, and preventive maintenance for clients such as the U.S. General Services Administration and Prince George's County Public Schools.

How much does a commercial HVAC unit cost?

Commercial HVAC costs vary significantly based on system type, building size, and project scope — a VRF system for a multi-zone office building carries a very different price tag than a single rooftop unit replacement. Holmes Mechanical Contractors provides project-specific consultations and quotes tailored to each facility's requirements.

How often should commercial HVAC filters be changed?

Commercial HVAC filter replacement frequency depends on building type, occupancy levels, and local air quality — high-traffic facilities in the Washington, DC–Maryland–Virginia metro area often require filter changes every one to three months. Holmes Mechanical Contractors offers preventive maintenance programs that include equipment inventory, evaluation, and scheduled filter service to keep systems performing within spec.
