Carlson Mechanical LLC

Carlson Mechanical LLC operates as an owner-operated HVAC contractor in Rocky Point, New York, serving Suffolk County with residential and commercial heating and cooling solutions. Jeff Carlson brings 29 years of field experience to every service call, and the company maintains NATE certification and full licensing and insurance coverage. The business has completed 5,103 installations and responded to over 8,320 service requests, earning a 3.8-star rating across 13 customer reviews. The company handles all fuel types including electric, gas, oil, and geothermal heating systems, plus the full spectrum of air conditioning applications.

What distinguishes Carlson Mechanical from other contractors on Long Island is their breadth of commercial refrigeration expertise and their participation in utility rebate programs. The company services ice machines, wine cellars, and commercial refrigeration equipment alongside traditional HVAC work, a combination rarely found in residential-focused contractors. They are PSEG-certified participants in the Cool Homes Program, meaning homeowners who qualify can receive rebates on energy-efficient equipment the company installs. This certification reflects competency with modern refrigerants and high-efficiency systems that many older contractors have not adopted.

Customer experiences with Carlson Mechanical reveal a service model that works well for some situations but has notable gaps. Reviewer Ellen Berberich described a same-day call where the technician diagnosed a circuit breaker issue in just two minutes, solving a problem another contractor had misdiagnosed as a failing outdoor unit. However, reviewer Valerie Titone documented a frustrating multi-visit scenario where a replaced coil still did not resolve cooling issues, and subsequent visits were declined. Another reviewer, Christina L., reported waiting four days for initial service and experiencing poor follow-up during a heating emergency.
