As a general rule: if your system is under 10 years old and the repair is under $1,000, repair makes sense. If it is over 15 years old, needs frequent repairs, or uses R-22 refrigerant, replacement is usually the better investment. We will always give you an honest recommendation.

A furnace burns gas to create heat. A heat pump moves heat from the air (or ground) and can both heat and cool your home. Heat pumps are more energy-efficient but may need backup heat during extreme cold. Many Long Island homeowners use a heat pump with a gas furnace backup (dual fuel system).

A ductless mini split is an AC and heating system that does not require ductwork. It consists of an outdoor unit and one or more wall-mounted indoor units. Perfect for room additions, converted garages, finished basements, and older homes without existing ductwork.

We recommend servicing your system twice a year: once in spring (AC tune-up) and once in fall (heating tune-up). Regular maintenance prevents breakdowns, extends system life by 5 to 10 years, and keeps your warranty valid.
