Major Air Service Corp.

What Major Air Service Corp. does

Major Air Service Corp. is a privately held, family-owned HVAC services company founded in 1963 in Long Island City, New York, and operating for over 60 years under Levine family ownership since the 1990s. The company specializes exclusively in air-cooled Package Terminal Air Conditioners (PTACs) and Water-Source Heat Pumps (WSHPs) — through-the-wall heating and cooling units used in multifamily residential, hospitality, and healthcare buildings — and explicitly does not offer broader HVAC services. Its service portfolio covers the full equipment lifecycle: new installation, retrofit and replacement, on-site diagnostics and repair, scheduled preventative maintenance, wall-sleeve replacement and installation, and heat section repair. The company operates a 14,000 sq ft dedicated repair facility and employs factory-trained technicians qualified to service all major PTAC and WSHP brands.

The business sells exclusively through direct customer outreach — phone (718-592-5100), email ([email protected], [email protected]), and website request forms — with a separate custom-quote process for projects involving five or more units. Its target segments are Manhattan luxury high-rises (co-ops, condos, rentals), hotels, and hospitals/nursing homes. Pricing is quote-based and not publicly disclosed. Differentiation rests on 60+ years of NYC-specific code-compliance expertise (DOB, ConEd load calculations, legacy building constraints), deep brand-agnostic technical capability, and a content-marketing blog aimed at property managers. Geographic scope is limited to the five boroughs of New York City.

The company is small (firmographics lists 1-10 employees, which appears to understate field technician capacity), has no subsidiaries, no parent company, no venture or private-equity investment, and no disclosed revenue. No AI, software platform, or technology-product line is offered; the company's value is delivered entirely through physical service delivery in a narrowly defined geographic and equipment niche.
