Recommended Customer Reviews
Atrocious customer service. All I wanted was for a heat tech to come by and take a look at the banging pipes in my house, but the woman answering the phone was so rude, dismissive, and generally unhelpful that I didn't think it was worth the aggravation.
We had a technician arrive late for an appointment and instead of coming inside, he parked in front of our house, and took a nap in his van. Other appointments were just missed for no apparent reason.
They are the best In the area! We have used them at various apartments over the years and just called for oil in our new house...We called today and they were here at 8:30pm! They have excellent customer service and professionalism...it was very much appreciated. Again, we have used a lot of companies for oil in the area, but Thermoil is the best.
We have used Thermoil for heating, cooling and plumbing services as we have moved around the area from Watertown to Belmont. Quality of work is excellent. Prices are competitive and often beat other competitors. They respond to emergencies in a short order. For non-emergencies, you need to be patient as it is the case with most building service companies. Excellent service all around.
Tara S.I spoke with the representative from Thermoil this evening, and it sounds like they are trying to make sure they are more customer-service oriented. I have had better service from them this year. I hope that continues, and it seems like they are motivated to keep their customers happy.
I called Thermoil for a few days before December 31st for an oil delivery but I was undecided. I called back last minute on the 31st, they were very busy but very friendly and I was told I would have heat by Friday the 2nd of January. I saw my heat was on the 31st so I called and the woman who always answers the phone told me they already made the delivery. I was thrilled, the service was great and I'd recommend them to all of my friends for oil.
They will cheat you out of your money. We ordered the minimum 100 gallons for our 275 gallon tank, and they came to deliver this morning. I had my suspicions after our last batch emptied out much faster than anticipated, so I went and checked out oil level after they left. 1/4th of the gallon was full. I don't know where they learned math but 100 is definitely not 1/4 of 275. When I confronted another guy who came later to prime our tank about this he denied that they did anything wrong. He had the nerve to say ""Well your tank was empty and now you have oil, what's the problem?"" Then I had a little math lesson with him and explained how 100 is 1/4 of 400, not 275.and then he shoves it off saying ""Oh derrr I don't know, you should call the main office about it"" I'm pretty sure they've been doing this for all the other times we ordered. Don't get oil from them if you don't want to be cheated.
After the huge snowstorm yesterday, I went down to the basement to check the heating oil level (probably should have done that BEFORE the snowstorm). Much to my dismay, it was below Empty. I called around and Thermoil was able to deliver oil the very same day. I was very grateful, especially since temperatures are supposed to hit -7 tonight. The delivery man was also very nice, even though it was 7pm and temperatures were around 12 degrees F.
They have earned me as a customer.
I can't comment on Thermoil's oil business, but I had a very good experience with their service technicians. We have gas heat and the furnace stopped working last night (a Sunday). With a 5 month old baby we really couldn't go without heat on a very cold night. I called a bunch of places, and Thermoil picked up right away and I received a return call from the Emergency Service Dept within an hour. They came shortly thereafter and fixed our furnace on the spot. Of course, I haven't received a bill yet, but it was one of those times where you are willing to pay whatever it costs. Thank you Thermoil!
This is an absolutely horrible company- if you have any choice go with someone else.
Customer service is terrible- rude, unfriendly, and they couldn't care less.
We also had issues with the actual service. They filled up the wrong tank leaving us without oil on a cold day. In addition, when the oil is cheaper than capped value, they do not fill up as much as they do when the oil is more expensive. Who does that?!?! What a scam.
