What T.F. O'Brien & Co. does

T.F. O'Brien & Co., Inc. is a privately held, family-owned HVAC, plumbing, and home services contractor headquartered in New Hyde Park, New York, founded in 1934 and serving residential and commercial customers across Long Island, Nassau County, West Suffolk County, Brooklyn, and Queens. The company installs, repairs, and maintains heating systems (heat pumps, boilers, furnaces, including high-velocity and wall-hung boilers), air conditioning (central, ductless/mini-split, and PTAC), plumbing (drain cleaning, water heaters, fixtures, leak detection, water filtration), standby generators, and indoor air quality solutions. Its core technology portfolio centers on Carrier products as a Factory Authorized Dealer, supplemented by Daikin VRV/VRF systems for commercial ductless applications. Service delivery is field-based, with technicians dispatched to customer sites; the sales motion combines direct-to-consumer marketing for residential work with engineered proposals for commercial accounts.

The company generates revenue across five streams: one-time HVAC installation projects, repair services (including 24/7 emergency), recurring subscription revenue through the Energy Saver Plan maintenance agreement, plumbing service work, and generator installation/maintenance. Pricing is quote-based and not publicly disclosed, with financing options available and promotional discounts on high-efficiency equipment. The customer base is split between residential homeowners (primary segment) and commercial businesses, with 25,000+ lifetime customers cited and a 4.9-star Google rating across 2,000+ reviews supporting acquisition. The business is supported by NATE-certified technicians, EPA certification, ACCA membership, a paid HVAC training program, and recognition including BBB A+ accreditation and Angi Super Service Awards. T.F. O'Brien has no disclosed institutional investment, no M&A activity, no subsidiaries, and no public listings—it operates as an independent, multi-generational family business.

Scale indicators5 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Carrier Corporation: T.F. O'Brien's primary OEM partner and a global HVAC manufacturer; comparable because the Factory Authorized Dealer relationship, exclusive product lines, and Presidents Award program structurally connect the company's economics to Carrier's distribution strategy.
• American Residential Services (ARS) / Rescue Rooter: Large national residential HVAC, plumbing, and electrical service platform; comparable as a scaled services operator serving homeowners with multi-trade capability, though broader geographically and PE-backed.
• Trane Technologies: Global HVAC manufacturer operating the Trane Comfort Specialists dealer network; directly analogous to Carrier's Factory Authorized Dealer program that anchors T.F. O'Brien's product sourcing and training pipeline.
• Lennox International: Major HVAC equipment manufacturer with a David Lennox Dealer Network of independent dealers; analogous role to Carrier in T.F. O'Brien's model, representing the broader incumbent OEM and dealer-channel structure in residential HVAC.

Regional players

• Hocon Industries: Connecticut/New York-area HVAC, plumbing, and fuel delivery contractor serving residential and commercial customers; comparable as a long-tenured, multi-trade regional services firm with adjacent geography to T.F. O'Brien's Long Island/NYC footprint.

Direct peers

• Binsky Home Services: New Jersey-based residential HVAC, plumbing, and electrical service company; comparable long-tenured multi-trade home services business with similar install/repair/maintenance revenue mix.
• Petro Home Services: Multi-brand residential HVAC, plumbing, and home services provider across the Northeast U.S., directly comparable to T.F. O'Brien in offering install/repair/maintenance across HVAC and plumbing for owner-occupied homes in similar geographies.
• One Hour Heating & Air Conditioning: National franchise network providing residential HVAC install, repair, and maintenance with emergency service; directly comparable business model to T.F. O'Brien's DTC service-delivery approach, particularly the 24/7 emergency focus.
• Cool Air Mechanical Services: Long Island-based residential and commercial HVAC contractor offering installation, repair, and service for heating and cooling systems; a directly competitive local peer serving the same Nassau/Suffolk customer base.

Others

• Daikin North America: HVAC manufacturer whose VRV/VRF products T.F. O'Brien installs on commercial projects (Manhasset case study); a supplier/enabler comparable because Daikin's technology and rebate programs influence the systems T.F. O'Brien can offer.
