Harold has been working on our HVAC systems for about 8 years after a large commercial firm did not do well by us. Harold is a throwback, where a handshake is backed up by someone who works tirelessly until your issue is resolved. We had our A/C condenser motor go out on a Sunday, Harold was there Monday, had a motor shipped overnight and now we are working on Tuesday.Besides being outstanding in his trade, Harold is also just a nice human Being.

Harold was great to work with. Very honest, professional, timely, and competitively priced! Would highly recommend. I have used his services at my business in Raleigh and my personal home in Garner.

I have had Harold from Advantage doing work on our Heating / AC units for a number of years, he does fantastic work. He is prompt, courteous and friendly. We made the mistake of going with Michael and Sons (never again) to install two new units, but after a number of disasters with Michael & Sons maintenance folks, we went back to Harold. Would highly recommend Advantage. Great folks.
