Traditional Work Ethic

"It is with great honour and respect that I write a letter of recommendation to the team at Orillia Natural Gas. We have received excellent, competent service at both our home and our professional building for many years, and it has always been done in a professional, scheduled, friendly, courteous, and timely manner. All of those attributes are hard to come by in a society and economy that has faced challenges and limitations. We rest peacefully at night knowing that our house is safe and warm, that the office is safe, and that should there be a problem with any of our natural gas appliances, ONG is only a phone call away as they provide emergency service also. "


"I am thankful that Len built the company and has made a wise choice in succession planning by passing the torch to Ellen, John, and their team. Amidst their business plans lay a traditional work ethic and that personal touch. Thanks to them for all they do for us. On a side note, our Intercity horizontal 50,000 BTU was installed in 1995 and with service and maintenance the unit is still going strong. "

My Review of Orillia Natural Gas - 5 Stars

"Ok so I messed up and pierced my refrigerant line with of all things a deadly weed whacker trying to make it look nice around my AC unit. Also, I am new to the area and not familiar with who to call to repair the damage. Googled it and Orillia Natural Gas came back with good reviews, so I called and spoke to Ellen (super nice lady) and scheduled their technicians for the earliest opportunity. The technicians arrived 15 minutes early (bonus) Rob & James greeted me masked, well groomed with friendly professionalism. They got right down to work, successfully repaired the pierced hole and had my AC up and running just in time for the hottest day of the 2021 summer so far. Bottom line my experience is a great company with great people, very professional and I highly recommend. Definitely my go to for all my future HVAC needs!"
