We had an awful experience with this company. - They installed a defective furnace in our home that made a loud banging noise (likely a refurbished product). They gaslit us for weeks, saying we were imagining the noise. After multiple follow-ups initiated by us (they didn't want to fix it), they reluctantly admitted they heard the noise and installed the correct furnace. - According to the Town of Madison, Wilcox installed a water heater without obtaining the necessary permit for installation - proof they cut corners to save a few bucks at the expense of safety and compliance. - Upon requesting propane delivery, they delivered the propane to the wrong house (they are so incompetent that they couldn't even remember the house they delivered to), but sent us the bill! They acted like it was no big deal, showing complete disregard for the safe handling of dangerous gases. When they showed up at my house post-error (they assumed it was a gauge issue at first), they inexplicably didn't even bring propane with them to fill up the tank! Despite having "reliability" and a "commitment to customer satisfaction" plastered all over their website, the owner of the company said he "didn't have the authority" to make it right and offer a credit for the hassle and inconvenience. We were gaslit again, saying we were being too hard on them and wanted empathy for the team hustling amidst staffing issues. Based on our experience, this is a sketchy, dishonest and unreliable company despite the empty BS jargon on their website - not to mention their products and services are grossly overpriced compared to their competition. UPDATE BASED ON WILCOX DIATRIBE: In Julie's long-winded diatribe, she admits they installed a furnace that didn't work (even though she comically doesn't think "defective" is a fair word), didn't obtain a water heater permit (either before or after the installation) and delivered propane to the wrong address. She conveniently didn't address someone who claimed to be the "owner of the company" (who really wasn't) not having "authority to make it right," basically admitting their website jargon is complete BS. It would be lovely if Wilcox spent as much time doing their job (which they do very poorly) as they do writing encyclopedias in response to customer reviews. They're so incompetent that they don't even realize that saying "we don't gaslight customers" is gaslighting in its purest form. Lovely company. read more

Lost our Heat at 3:30 am. Avery came and diagnosed the problem. Replaced some parts and within 25 minutes the problem was corrected & we had our Furnace back heating our Home. We've been Customers of Wilcox Energy for 8 years. Avery , our Technician, is a knowledgeable, personable young man. Thanks so much!! read more

Prompt gas delivery, they have a great hvac service department as well. fixed the problem with no issue.

I love Wilcox! I have lived in Saybrook for 20 years and have only used them. I have NEVER been disappointed. When I call for fuel they are there within 24 hours, when I have called for service either heat or a/c they have come out same day. I recommend them to everyone locally! read more

Wilcox installed the propane tanks and lines for our generator a couple years ago and did an excellent job. We ran into a problem this week with our central air (not installed by Wilcox) and gave them a call uncertain if they would be able to help us. They responded affirmatively and actually had two Techs out to our house 4 hours after we called them. They quickly diagnosed the issue (blower motor failure) and were back at 9 the next morning to disassemble and clean everything and install the new motor. We were back in business in a little over 24 hours, and ready for the upcoming warm up . Amazing! Cannot recommend them highly enough. They are responsive, knowledgeable and professional at every step. read more

We have used Wilcox for over 20 years. We are very satisfied customers. Their employees are courteous and knowledgable. They answer all my questions. We lost heat during a sub zero night. Within hours of an emergency call they were out to the house and their technician solved the problem. We regularly get our furnace cleaned, we do budget payments and lock in our rate and delivery has never been an issue. read more

See all

Excellent service and very clean. Professional and they know what they're doing as far as what should be recommended for your house. Work was done efficiently and they answered all our questions thoroughly. Any plumbing work is very expensive but you will not be disappointed with the quality you get with them. I especially want to thank Jared who came out to stop the leak from our boiler that blew when the hot water heater went on the weekend! He was at the house within 20 minutes after I called. Also want to thank John who did our hot water heater work after the fact. He was with another worker who was very nice as well but I am sorry I do not know his name. I would highly recommend and trust Wilcox for your needs. read more

I just had the best service ever for a Wilcox a/c check. The technician (Jake) was professional, polite and friendly and explained the whole process to me very clearly. In addition, the office staff is always wonderful! I highly recommend Wilcox Fuel. read more

Top notch service, if you still enjoy good customer service, these folks are for you.

A while back, my elderly mother's central A/C drain got clogged, and she hired the first place she called to fix that on an emergency basis. She recently got a mailing from that company offering to do a low-cost check of her system, which she had done. While she described them as 'very nice,' they terrified her with talk of dirty/moldy ducts and a system that needed replacing, telling her she shouldn't ever turn on her existing A/C anymore as it needed to be totally replaced. Since she never had any problem with the A/C except the one clog, I researched reputable companies and Wilcox Energy stood out (plus it turned out that many of my mother's friends have happily used Wilcox for decades). My mother had Wilcox come to check her system, and they did a 'tune-up,' replaced the filter, and told her it would be fine to use for now--and it is currently working well. We are so happy to have identified an honest, highly reputable and well-established local company to meet her needs! read more

I have had Wilcox for my fuel oil delivery ,furnace cleaning and air conditioning needs for twenty years. They have always done a fi ne job. Just recently I had them remove my old oil furnace and air conditioner and install a new propane unit and air conditioner. The job was done neatly and professionally and I am happy I made the change to propane and with Wilcox read more

I had Wilcox install a new Air conditioner Unit. Great communication from the quote through the installation. Installed when promised. Their employees were courteous and answered all my questions. They cleaned up as well. Would highly recommend them to anyone. read more

We had to switch to another heating oil company because several times I caught their driver looking in our window when delivering oil. When I complained to the owner, he in as much said, he didn't believe me. read more

We have used Wilcox for nearly two years. Service has been very reliable and quite responsive. The one issue we had with the Furnace they addressed quickly and professionally, and the annual tune up has clearly kept the furnace and hot water system in good shape. I was surprised to see the negative review; our experience is completely different and positive. Fred C read more

I am very disappointed with the billing and customer service related to my oil delivery service. I requested very clearly what my needs were. My payments were applied to services I didn't ask for and when checking what I was billed for I feel I was over charged for that. I am employed in a customer service company. There might be someone that is trained in customer service, but I didn't find them. I therefore can NOT recommend this company. read more

Integrity and customer service, two outstanding qualifications that sets them apart from their local competitors. In this day and age it's sometimes hard to find a company that stands out and goes above and beyond to meet their customer's needs. Wilcox Energy does just that. I can't recommend Wilcox enough. read more
