What are the advantages of switching to a ductless mini split system?
Ductless mini split systems offer several benefits. They are energy efficient, operate quietly, and provide zoned temperature control, allowing you to heat or cool specific rooms as needed. These systems are particularly suitable for older homes without existing ductwork, new home additions, or for homeowners aiming to reduce energy expenses while maintaining comfort.
How do I know if my gas boiler or furnace needs to be replaced instead of repaired?
Replacement may be more cost-effective if your heating system is older than 15 years, requires frequent repairs, or is causing a significant increase in your utility bills. Our technicians can conduct an assessment to determine whether repairing or upgrading your system will be more economical in the long run.
Is geothermal heating and cooling really worth it on Long Island?
Geothermal systems are indeed a worthwhile investment on Long Island. They are among the most efficient and environmentally friendly heating and cooling options available. While the initial installation cost is higher, these systems can reduce energy bills by up to 70%. Additionally, state tax credits and rebates are available to help offset the installation expenses.
Can a mini split system heat my home in winter or is it just for cooling?
Modern heat pump mini split systems are designed for year-round use. These advanced systems efficiently provide both heating and cooling for your home, performing effectively even during Long Island's colder winter months.

What's the difference between a traditional HVAC system and a heat pump?
Traditional HVAC systems use separate equipment for heating and cooling, whereas a heat pump provides both functions using electricity. Heat pumps are generally more energy-efficient and are particularly well-suited to Long Island's moderate climate, especially when integrated with mini split or geothermal systems.
How do I know which heating or cooling system is right for my home?
Determining the right system for your home requires a comprehensive evaluation. Our technicians assess various factors including your home's size, insulation quality, layout, and your comfort preferences. Based on this assessment, we recommend the most efficient and cost-effective solution, which could be a gas boiler, mini split, or geothermal system.
How quickly can Energywise install a new heating or cooling system?
For standard systems, installation can typically be completed within one to two days following the initial consultation.
