Our guarantee of 100 percent customer satisfaction applies to every household we serve.

Our goal is to find a positive outcome and enjoy the experience of pleasing our customers.

These guys did an incredible job for me - careful - meticulous attention to the smallest detail - considerate - competent. I am just going to put it this way - this is the second full installation that I've had done in this house which I have lived in for 35 years - I have worked with a couple of ac and heating contractors - these guys set the high water mark for everyone else!read more

Very pleased with the service provided by this family run business. My unit went out last night before the Labor day weekend. As you can imagine, finding help on a holiday weekend isn't the easiest. Justin and his Dad were very helpful when I called earlier today to help me get my unit back and running quickly. Great service and a pleasure to do business with. Highly recommend for any of your HVAC more

I simply could not more HIGHLY recommend an AC/Heating Co as I do Krantz Kooling and Heating. Long story short ...My air went out Wednesday and all I can say is that from the moment I contacted these fine folks they have provided me nothing but EXEMPLARY Service. From the kind and wonderful ladies I spoke with on the phone to the initial guy John who diagnosed my issues which lead to a subsequent visit from Justin Krantz (who I very importantly might add here so very kindly and patiently took the time to explain in layman's terms to me all things AC🙌🎉) to the also very AWESOME and 2 fine gentlemen (Chris and Sebastian) who showed up promptly at 9 am as I was instructed they would be and who are still here at my home now as I am writing this installing a brand new complete heating and air system on their weekend, all I can say is that they certainly "represent" in a most honorable and dignified fashion and most certainly could and SHOULD be used in this Industry as the measuring stick to which all AC/Heating Co's should aspire to conduct business EXACTLY like. KUDOS to this absolutely wonderful group🙌🎉❤️! If I could be allowed to give a higher rating than 5 Stars I would without hesitation. #myheroes 🎉😍 #inowhaveac❤️💃 #loveKrantzkooling&heating❄️😘read more

If you need a great heating and cooling company let this be your first and last call. I had 4 different people out to look at my unit and they were the only company to figure out what was wrong with it instead of trying to make me purchase a brand new one they helped me get it Fixed in a reasonable time. I would highly recommend more

I wish all businesses had this kind of customer service! These guys are hard-working, kind, fast, and thorough. After we received a new unit from them, my husband mentioned it to a co-worker . . . last count, 9 of his co-workers have called Krantz Kooling & Heating based on our experience, and they have exceeded expectations every time. We wouldn't think of using anyone else!read more

Krantz is the company you want for all of your HVAC needs. We have done business with them for many years and they have handled everything from service to replacement. They are knowledgeable, RELIABLE, and respond quickly to service requests ( even in a 4th of July crisis!). I have spoken with various people in the company and all are courteous, polite and professional. I would not use anyone else!read more

I am a commercial property manager with one of the top firms in SC. I have been doing business with Krantz since '07, and these guys are top notch in both commercial and residential HVAC services. Much like finding a good plumber or electrician, it is not easy to find a good HVAC company that you can trust. With Krantz, you can confidently rest assured they have your best interest in heart for your next quarterly preventative maintenance or energy savings HVAC project. Local family that cares about local people, yet professional and always competitively more

The very best when it comes to customer service satisfaction, before replacing any hardware and making you spend to much. Rest assured Krantz cooling will go above and beyond to fix or troubleshoot your unit before replacing it. Saving you time and money. Very reliable and very trust worthy people. Not just once they helped me but twice, especially on a cold winter night spare of the moment kinda thing. 2003 The week before I was deployed to Iraq Krantz Cooling & Heating fixed my AC unit I was rest assured my family was safe and sound with no trouble. I highly recommend Krantz Cooling & Heating for your more
