“Prior to the heating service of 2023-2024 My wife and I contacted Gross Heating who have serviced our broiler and gas furnace in the past and again prior to winter to make minor repairs. The service repair man was John G. and did the repairs in one visit. As a result, our heating bill went from $600+ in 2023 to $320. This has been consistent to the course of this winter and each and every month has been 50% or greater in savings to us, in respect to billing.
I would highly recommend Gross Heating, they stay by their word, and do the work necessary to give us the best possible product with the best savings.”

“I am extremely pleased with the service on my furnace and humidifier that Harrison did today. He was very knowledgeable, polite and courteous. I appreciated him explaining everything to me. We have had Gross Heating for many years and have always been pleased with your service. And I would like to thank your receptionist who took my call for being so pleasant and helpful.

“This is the third furnace installation for us by Gross Heati.
They are prompt, reliable and polite. They give great service if any problems occur. They even came right out once on Christmas Day! We have used their services for over thirty years and have found them to be reliable and have recommended them to friends and family.”

“Randy Belongia replaced the ignitor in our furnace. He was in and out within an hour. During that time explained our furnace to me and what parts are bad. Also some things look for in the future that could bring on more problems. Not only will I recommend Gross to others because of Randy, I will definitely use Gross in the future. Randy was very efficient and informative. Thank you very much!”

“Team from Gross installed a new boiler/water heater/thermostat with a high degree of efficiency and professionalism!! We wouldn’t trust any other company to upgrade our heating system. Ask for Jerry when you need service or quote on new system, over 30 years of experience!!”

I truly appreciated his excellent communication skills. It was a pleasure having him complete this job and providing for my family, “peace of mind”, that it was a job well done. Thank you so much, Harrison. JR”
