Long Island Insulation Services

ENERGY STAR estimates that 9 out of 10 homes in America are under-insulated. By preventing heat flow and energy loss, insulation—especially when combined with air sealing–plays a crucial role in energy efficiency. Home Efficiency Experts installs several types of insulation in Long Island homes, like spray foam, blown-in cellulose, and foam board insulation

Our team takes a building science approach to our work, which not only allows us to recommend the best type of insulation that will meet your home’s specific needs but also to verify that our completed work has made an improvement in its energy efficiency.

Heat Pump & HVAC Installation on Long Island

Having reliable heating and cooling is crucial to your home’s year-round comfort. Home Efficiency Experts installs a wide range of high-efficiency HVAC systems and can help find the best one for your Long Island home. Before we install a new heating and cooling system in a home, however, we always check for leakage and poor insulation first. If your home has significant air leaks and insufficient insulation, the size of your heating or cooling load along with the performance and lifespan of your new HVAC will all be affected. 

Here are the HVAC systems we install in homes throughout Nassau and Suffolk counties:

  • Ductless Mini Split Heat Pumps Get all-in-one heating and cooling without connecting to a central duct system with an all-electric mini split heat pump installation.
  • Ducted Heat PumpsHeat pumps use significantly less energy compared to traditional HVAC systems because they move heat instead of creating it. Ducted heat pumps can connect directly to your home’s central ductwork. 
  • Central Air ConditionersWe install ENERGY STAR-certified air conditioning systems that can reduce your energy usage without having to sacrifice your home comfort. 
  • High-Efficiency Heating SystemsIf your home uses gas or oil, installing an ENERGY STAR-certified furnace or boiler can help you save on your heating bills every winter.
  • Hybrid Water HeatersGet a reliable hot water supply in your home by installing a hybrid water heater, which offers heat pump technology and electric resistance heating for times of high demand.
