Temperature Control Systems

Temperature Control Systems holds a perfect 5.0-star rating across 11 reviews, making them Ronkonkoma's highest-rated HVAC contractor. Based in Ronkonkoma, NY, this full-service company serves Suffolk County with both residential and commercial capabilities. Their service territory spans from Huntington to Montauk along Long Island's eastern end, covering neighborhoods including Smithtown, Babylon, Bay Shore, Central Islip, and Patchogue. The company handles air conditioning, heating, furnace, boiler, and heat pump work, along with commercial refrigeration systems. They maintain extended weekday hours from 6 AM to 7 PM and Saturday availability from 9 AM to 3 PM.

What distinguishes Temperature Control Systems is their specialized focus on commercial refrigeration alongside traditional HVAC work, a combination fewer contractors offer on Long Island. Their website describes responding to a restaurant owner's emergency walk-in cooler failure at 11 PM, arriving within 45 minutes to prevent an $8,000 inventory loss. They emphasize a 90-minute average response time and stress they are a local operation, not an out-of-state call center. The company notes their technicians understand the specific challenges Long Island homeowners face, from PSEG rate hikes driving demand for efficient systems to the humidity that strains AC units during August heat waves.

Reviewers repeatedly highlight specific technicians who delivered exceptional service. One customer described calling on a Sunday and receiving a callback within five minutes from Larry, with technician Alex arriving the next morning to fix a cooling unit that another contractor had installed incorrectly. Another reviewer praised Alex for troubleshooting an intermittent central AC problem quickly and sourcing needed parts fast. A third customer specifically noted the team treated her with a "no problem we'll take care of it" attitude. Multiple reviewers mentioned reasonable pricing alongside the quality of work, with one noting the technicians explained problems clearly and delivered no surprise charges.
