24/7 HVAC OF LONG ISLAND INC

We’re 24/7 HVAC OF LONG ISLAND INC, based in Lawrence, New York. With more than 50 years of experience serving Long Island, we provide comprehensive heating and cooling solutions for residential and commercial properties throughout Long Island and Queens. We’ve built our reputation on reliable service, quality workmanship, and exceptional customer care. We are fully licensed and insured, and our team consists of highly trained, certified HVAC professionals.

Our services cover the systems that keep homes and commercial properties comfortable throughout the year. We install furnaces, repair boilers, and help ensure heating systems are ready for the winter months. For warmer weather, we provide professional air-conditioning installation, maintenance, and repair. We also install and repair ductless mini-split systems for energy-efficient climate control. As a Fujitsu Elite Plus Contractor, we have achieved Fujitsu’s highest contractor designation for HVAC installation and service. Our factory-trained technicians hold advanced certifications and bring careful, professional attention to every job.

We begin by thoroughly assessing the system and providing a clear, upfront quote for the recommended service. Once work begins, our technicians complete it efficiently and explain what they have done so our customers understand the service they received. Because heating and cooling problems do not always happen during regular business hours, we are available 24/7 for urgent HVAC needs. We stand behind all our services with a 100% satisfaction guarantee and remain committed to helping our residential and commercial customers stay comfortable in every season.
