Here is what our customers are saying…


Joe from Huntington

We just had our system changed to all heat pumps including our hot water. These guys were great. They explained everything before they started. Were on time for the installation. Kept good communication so I always knew what they were doing and when. The installers were great. Clean, friendly and did a wonderful job. And on top of all this they got me a substantial rebate and arranged the financing. 

A real class act. I highly recommend them.”

We recently moved into a large home built in the early 1980’s that was inefficient in every way imaginable. We hired Home Efficiency Experts to replace both our heating and cooling systems, as well as to insulate the house. The project required 10 days of actual work over the course of 2 weeks plus multiple one-off visits for planning and fine-tuning.

The team was very professional and skilled at all aspects of the work. From determining the right solution to our efficiency issues, through handling the analysis and cash flow implications, managing all administrative work (purchasing, financing, logistics, etc), engineering, hvac, light carpentry and client hand-holding.

They put a project manager on the project to oversee all stages and ensure client satisfaction. Bill Thorpe was our PM, and you should consider yourself in good hands if he is assigned to your project.

4 out of 5 stars is nearly unheard of for a contractor that covers this amount of work scope and a lot of $ at risk. I would have given them 5 if they did a 2-week job in only 1 week!”

Recently had a new A/C system installed, new hot water heater and insulation in the attic…all new modern thermostats…..vey professional service, took care of my concerns….and they made extra trips to the house to help me figure things out when necessary. Great personalities also.”


Angela from Shirley

“I was unsure about having a heat pump installed to replace my oil heat, but after Home Efficiency insulated my home and heat pump, my house is much more comfortable and my utility bills are much lower.”


Ron from Babylon

“I was skeptical about having an energy audit done on my home. The process was easy and the work they did on my home was done professionally and timely. Bill came to the house before the work was done, and went over the whole project with me. I felt completely comfortable with the entire process.”


Andres from Coram

“They replaced my old air conditioning system and boiler with a heat pump that heats and cools the house. The house is now comfortable all year round. I would highly recommend them to my friends and family.”


Margaret from Smithtown

“I had my attic insulated and sealed. Cathy listened to my concerns and asked a lot of questions. They were all very nice, neat and worked well together. The house is more comfortable, and we use less oil. My Central air doesn’t run all day long anymore. We are very happy.”
