Courteous, Professional and Efficient!

One of the best companies that I have ever worked with! From my first phone call to the final walk through, everything was impeccable! Al Giordano was just amazing, explained everything upfront and took the time to answer all my questions and address my concerns. Jason, Brian and Nick were fantastic and I cannot stop raving about them to my friends and family! I would recommend them over and over again, courteous, professional and efficient! Call Guaranteed Service, you will not be disappointed!

I will definitely use them again!

Truly great service, Joe is an excellent technician. He took the time to explain everything he was doing and answered all of my questions. Im so glad I took advantage of the tune-up offer that Guaranteed Service was offering. I will definitely use them again for my maintenance service in the future and would highly recommend this company.

Best HVAC experience Ive ever had.

The guys at Guaranteed are the best. Al Giordano was friendly, on time and knowledgeable. He helped us pick out the best system for our home. Brian and Nick installed the system in one day. They were efficient, respectful and clean. The job came out better than I couldve imagined. Best HVAC experience Ive ever had.

The answering service was not helpful at all but once I spoke to the office they were quick to assist. The work was done promptly and done well.

We had King George Plumbing install an industrial strength sump pump 9 months ago, and it performed great up until a week ago. For some reason the pump started running continuously without shutting off. After calling KGP, they promptly scheduled Danny to come out to investigate the issue. He quickly uninstalled the system; identified and fixed the problem; and then reinstalled the pump system. It is now working like a charm. What surprised me was that when I received the bill, we were NOT charged anything for the rework. We've been using KGP for years, and what impresses me is that stand behind quality work. In this rare event where a rework was needed, I was not double charged for it. Thank you KGP!

KGP provided a number of services for me over the past year -- HVAC, new sink, new toilet, new water heater, expansion tank & shutoff valves. They also repaired a leak that originated with the dishwasher. Their workers are very polite, professional, on time .
