Review of Wilcox Energy

My wife and I have been doing business with Wilcox Energy for several years for oil, propane and service so when our central a/c unit stopped working properly I called them. They had a technician out the next day who diagnosed the problem as a massive air leak in the outside coil and it would be better to replace the entire unit I asked him to have the sales rep give me a call with a quote. The sales rep called with a very fair quote the next morning and I said yes and when could they start the work. He said he would talk to the service department for scheduling and also relay to them that my wife and I are older and are affected by the heat. The service manager called me at 730 am the next morning and asked if it would be okay if they installed it that day and I said yes An installer Nick was at my house half an hour later and started taking the old one out while another person went and picked up my unit Nick was very knowledgeable and explained the entire process that was going to take place. He worked all day and had the unit operating by 300 pm. He then explained and showed me how things might be different on my new unit. From diagnosis to a complete new a/c unit was only 3 days. A fantastic job was done by the entire Wilcox Energy team and we are a completely satisfied customer Thank You

AC Service




Review of Wilcox Energy

Dear Wilcox Oil - I want to take a moment to thank Jared Zanelli for his excellent service on our AC Unit. He was incredibly thorough, took the time to illustrate and explain what was being done and left the AC in better running condition than it has been in years. He left the job site spotless and obviously has an eye for detail. Thanks Jarred for taking your job and customer satisfaction seriously. Sincerely, Adam McEwen

Propane conversion, with a phenomenal team all around




Review of Wilcox Energy

My family recently moved into a home with a 45 year old oil heating system which was begging to be laid to rest. After speaking with a number of local companies, and reading ton of good reviews about Wilcox, I contracted with them to convert us to propane. Every Wilcox representative I worked with was extremely pleasant, knowledgeable, and patient enough to answer my endless questions about propane and our new system. The work was done over two days, and they gave my and my wife regular updates, walked us through the process, and what we should expect next. It's a strange thing to say about replacing my heating system - but this was a great experience, and it gave me a tremendous amount of confidence in the company and their crew. I absolutely trust these guys to do whatever maintenance/repair we'll need in the future.
