High-Efficiency Heating And Cooling Solutions
Insulation
Insulation for your Long Island home will create a barrier so that heat can’t escape during winter months and you’ll be better equipped to keep cool air inside during the summer months. It’s important to properly insulate and air seal your house so that your utility bills don’t increase and become more than you can afford.
Putting a proper seal around the building envelope will make your home more comfortable, healthier, increase its value, and (most importantly) save you money!
-
Seal up holes from pipe and wire penetrations from the basement to the attic to minimize leaks where heat can escape and cool air can be infiltrated by hot air.
-
This is one of the best insulation materials you can use in your home. The benefits of cellulose insulation include:
50+ year durability—will not break down like fiberglass insulation
Fire-retardant
Controls moisture
Insects and critters can’t nest in it
Dampens noise
-
This is used for pull-down staircases and storage sheets. If you have an attic that has storage and or an air handler, we can install foam boards so that you can use the space for storage, or for easy access to your HVAC unit without disrupting your cellulose insulation.
-
Used for air sealing and generally considered the best and most effective option, spray foam reduces air leaks, improves energy efficiency and more importantly, lowers the cost of heating and cooling your home.
Heating & Cooling Replacement and Upgrades
Once your home is properly insulated and air sealed, a new high efficiency HVAC system can go a long way towards minimizing your energy bills and creating more even comfort levels throughout your Long Island home. Home Efficiency Experts specializes in money-saving, long-lasting HVAC system installation, including:
-
New ENERGY STAR-certified central AC units can keep your home comfortable all summer long at a fraction of what it costs to run your older existing cooling unit.
-
Is your heating system more than 15 years old, or frequently breaking down? Upgrading your HVAC system can help you start saving money immediately, and Home Efficiency Experts can help with oil to gas conversions as well.
-
For homeowners looking for all-in-one HVAC solutions, ultra efficient heat pump technology is the way to go. Ducted heat pumps and ductless mini-splits offer flexible installation options, heating and cooling settings for year-round operation, and with high efficiency, all-electric operation, you can drastically reduce your energy bills.
Long Island Home Energy Assessment For Better Comfort And Savings
An assessment isn’t just an educated guess—it helps pinpoint your home’s specific weak points, and your home energy assessor will be able to walk you through the results, and explain their recommendations for home retrofits that will make the biggest difference to your home comfort, as well as your energy savings.
Energy efficiency upgrades are also much better for the environment. You’ll lower your carbon footprint by switching from fossil fuels to clean, renewable energy sources, and lowering your overall energy usage every month with a tighter building envelope and more efficient HVAC equipment.
