Energy saving solutions and services

Whatever your energy-saving issues are, our technicians can identify them with our top-to-bottom, no-cost home energy audit. From the attic to the basement, from insufficient home insulation to drafty windows, our savvy professionals will leave no stone unturned, identifying uncomfortably hot or cold rooms, fluctuating temperatures, causes for high heating or cooling costs and what services can resolve them.

Whether you need to replace your faulty home insulation to spray foam, rigid foam, ProWool, or blown in, or you need to update your old, overworked HVAC system, or you need upgrades for defective, drafty windows, we have these energy-saving solutions and more!

Air sealing home insulation experts

Does your home feel uncomfortably chilly in the winter and too hot in the summer? Insufficient, thin, weathered home insulation and poor air sealing may be to blame. With an inadequate attic, crawl space, or basement barrier, your utility costs will rise as your HVAC unit continuously runs trying to regulate home temperatures.

Triple H Home Efficiency Experts is Nassau & Suffolk Counties's complete insulation contractor offering spray foam, blown in, cellulose, and ProWool insulation for crawl spaces, basements, attics, basements, and walls.

Trusted heating and cooling professionals

Brisk winters and scorching summers are no match for Triple H Home Efficiency Experts – whether your Nassau & Suffolk Counties home relies on a boiler, furnace, air conditioner, or water heater for its hot water or treated air supply, we provide replacement and installation solutions for all of them. Tired of rollercoaster pricing and insufficient heat coming from your old oil-burning heating system? No problem, we can also convert your oil heating unit to natural gas.

We provide quality HVAC solutions that can help you save money on utility bills and maximize your home's comfort for years to come!
