Our service technicians were highly competent and friendly. They quickly diagnosed the problem with our furnace and repaired it. We have loved working with Isaac's since our very first installation! We highly recommend them!

Had to have another plumber come in a fix installation mistakes Issacs made. Was told I was charged for a vent I never received. Still wanting on a call back about another issue. Techs were all really nice but business practices aren’t great.

Thank you for the opportunity.
Jacob was very professional in correcting unfinished work and making sure that everything was done to my satisfaction.
He even went so far as to point out some performance factors that I should watch going forward.
Perfect 10 out of 10!

After digesting what I was told by an Isaac tech who said my repair would be around $3500 AND your Sales person quoting a price of $15,000 for a not complete new unit, I decided to call my original installer, who had to temporarily end his business due to very serious back issues. He decided he would come to our house with the one part I needed. He installed the needed part in less than ten minutes and charged me literally next to nothing for the repair! Now we have wonderful heat and all is functioning well. My recommendation to Isaac would be to have all their employees were masks when they show up at your house (like the one the Lone Ranger used to wear)!!!!!!

Jacob came to our house last week to clean and fix the furnace and its blower and answered all of our questions! He was knowledgable, respectful, clean and wonderful and we would recommend him to anyone in the area (Horseheads) with a similar issue! Thank you!
