Quick Answers

Does J & L Mavilia handle commercial HVAC, not just residential systems?

J & L Mavilia is exclusively a commercial mechanical construction company — the firm does not service residential properties and specializes in systems such as rooftop units, chilled water systems, boilers, air handling units, cooling towers, and heat pumps across government, healthcare, office, and industrial facilities in the Upper Marlboro, MD area.

How much does a commercial HVAC system cost?

Commercial HVAC system costs vary widely depending on building size, system type, and scope of mechanical construction required — J & L Mavilia provides project-specific quotes and can be reached at 301.249.1506 to discuss your facility's needs.

When should a commercial HVAC system be replaced?

A commercial HVAC system typically warrants replacement when repair costs exceed roughly 50% of replacement value, efficiency has significantly degraded, or the equipment exceeds its designed service life — a mechanical contractor like J & L Mavilia can assess the current condition of rooftop units, chillers, boilers, and air handling units to help facility managers make that determination.

About

J & L Mavilia is a family-owned mechanical construction company based in Upper Marlboro, MD, serving commercial and government facilities within a 25-mile radius for over 30 years. The firm holds NAICS code 238220 (plumbing, heating, and air-conditioning contractors) and has built its reputation primarily on Federal Government mechanical construction projects, making it a well-practiced resource for facility managers overseeing government buildings, healthcare facilities, educational institutions, and mixed-use or industrial properties in the Prince George's County area. J & L Mavilia services a broad range of commercial HVAC equipment, including air handling units, boiler systems, chilled water and chiller systems, rooftop units, cooling towers, and heat pumps — the core mechanical systems found in mid- to large-scale commercial buildings throughout the Washington, DC metro region. Maryland's climate, with its hot, humid summers and cold winters, places heavy seasonal demand on all of these system types, and the company's three decades of regional experience positions it to address maintenance and construction needs across the full mechanical scope. Facility managers can contact J & L Mavilia directly at their Upper Marlboro office by phone at 301.249.1506 or by email at info@jlmav.com to discuss project requirements.
