What Our Clients Think...

The service tech (Jahn) was knowlegable, very polite, efficient and just a nice guy. The office staff (Debbie and Kim) were professional and helpful. There is a service call charge which is explained up front. Well worth paying for in my opinion. Service arrived in less than 45 minutes then immediately identified the problem as a bad Ignition Control Module . Jahn suggested In I purchase their service contract to avoid the service charge on the next call.
Great River Homeowner

Lori S Bayshore
We had an excellent experience with Energywise, Inc. I would recommend them to friends and family. The service man was very knowledgeable and their price was better than all the other companies that I had called for estimates.
Grace Patchogue
Was very impressed with knowledge of both servicemen. Felt very comfortable that the information they were providing was accurate. Would definitely recommend them and will use them in the future.
