Sheffield Heating & Air Conditioning

Sheffield Heating & Air Conditioning holds a 4.6-star rating across 30 verified reviews, reflecting consistent service quality in the New York City market. Based at 318 E 9th St in Manhattan, this contractor operates Monday through Saturday with extended evening hours and maintains Sunday availability for emergency calls. The business serves residential and commercial clients throughout Manhattan, Queens, and Brooklyn, offering both new installations and repairs for aging systems. All technicians are certified and insured to perform HVAC work within NYC and neighboring regions.

This contractor distinguishes itself through specialized PTAC (through-the-wall air conditioner) expertise, a niche less common among general HVAC providers in the metro area. Beyond standard split systems, they stock and service PTAC units, window units, and thru-the-wall configurations along with related components like heating coils and water storage heat pumps. Their service menu includes AC winterization, critical for second homes and seasonal properties, as well as air duct cleaning and preventive maintenance agreements. The company advertises 24/7 emergency response with same-day arrival for urgent repairs, a practical differentiator during summer heat waves or winter cold snaps when system failures spike.

Customer narratives from verified reviews describe specific technicians managing distinct scenarios. Ian appears in multiple reviews, guiding homeowners through full system replacements with detailed explanations of equipment selection and performing thorough post-installation cleanup. One reviewer noted a technician arrived shortly after a leak call, provided maintenance guidelines, and called ahead when running behind schedule. Another detailed how the team resolved urgent heating issues for a reviewer whose system failed during a holiday weekend, highlighting the company's emergency availability.
