Great AC Service/Fix




Review of Wilcox Energy

Vidal came quickly, at short notice, he was polite, listening to my explanation and let me know exactly what he was going to do and what problem he was going to look for. The AC was fixed in no time and all the cost options discussed before we decided how to proceed. Everything is working well now. Thanks!

Excellent same day service for urgent problem




Review of Wilcox Energy

Mr. Velez responded to a call on the same day of our call, fitting us in for a split unit not providing any cooling. He quickly established the problem, explained the steps necessary to test and then repair the system and made time to get the whole job done on the same day. Compared to HVAC technicians from other companies, he was very thorough and knowledgeable. Excellent service! Pricing is from Wilcox Energy and is reasonable for market rates (which are high right now, especially refrigerant prices).

Absolutely Great Service!!!




Review of Wilcox Energy

I've used Wilcox since 1999 when I first moved to this house. I received a recommendation from a former friend in Woodbridge and have never been disappointed..The cost has always been reasonable and the service has always been excellent in every way whether on a scheduled or emergency basis. Technicians have been skilled, helpful, courteous. Today Jared Zanelli came to tune up the air conditioning and did a repair to prevent potential problems. I am very grateful . I am pleased to be able to provide feedback and will continue to recommend Wilcox to friends.

Same-day service, helpful technician




Review of Wilcox Energy

I was pleased that Wilcox gave me same-day service to address a burner fault I was having. (I have a service contract.) The field tech, Michael, diagnosed the problem within moments, and communicated his plan to fix it. He took a minute to educate me about my system, and proposed an improvement that would eliminate this problem in the future.
