Home Energy Audits

One of the first steps before any energy-saving services can be performed is to conduct a home energy audit. A home energy audit allows us to assess the current energy efficiency of your home and determine what services may be of use to your family.

When performing an audit, our Long Island HVAC experts assess your:

  • Ductwork
  • Insulation
  • Walls, attic, roof, ceilings, and basement
  • Heating and cooling systems

Using advanced technology and the most up-to-date equipment, we can carefully analyze potential problem areas in order to tailor our energy services to meet your unique needs. We can also assist business owners by performing a commercial energy assessment.


Proper insulation is imperative to a comfortable and energy-efficient home. With so many opportunities for conditioned air to escape and for outdoor air to come inside, it is important to invest in effective insulation. Insulation can help save you money by improving your HVAC system’s efficiency and improve your indoor air quality.

Oil to Gas Conversions

Oil prices are unpredictable and far higher than natural gas prices. For this reason, many homeowners choose to convert their HVAC systems from oil to gas. Master Plumbing Heating Cooling can help you determine whether converting to natural gas is in your best interest. Most homeowners see energy and money savings soon after making the switch.

We look forward to providing your family with energy-saving services. Call us at (631) 328-2585 to get started.
