A family owned and operated local business that gives top-notch service for a fair price. They know their business and are honest - they won't try to up-sell you if you don't need it. I've been with Krantz for over a decade after my old guys tried to sell me a whole new unit when all I needed was a $350 repair. If you start using Krantz, you won't be sorry and you won't ever have to look for another HVAC company.read more

I have been using Krantz for several years for both repair and to replace old units. They are the best. I have recommended them to others and they are equally satisfied.read more

Highly recommended. I had a great experience. Same day service for my AC unit which was taken out by a lightening strike. Worked until 7pm on a Friday to get it going for the weekend while a part was ordered. Corry and Justin were hardworking and courteous.read more

I received the best customer service from Krantz Kooling & Heating. Everyone I talked to was great and very courteous. My AC unit went out and I was on the fence of whether it should be repaired or replaced. They gave me all the options and recommendations with no sales pressure. They repaired my older unit and it runs better than ever. Saved me a lot of money. They put my best interest first. Could have not had a better experience. Highly recommended.read more

Justin was super friendly on the phone and got a technician out to our house immediately due to our newborn and our heat going out overnight. John came over was quick to assess the issue, made a recommendation and fixed the problem all in two hours hours. Great people, very knowledgeable and quick! Thanks!

We've used Justin and his crew for our homes - we've moved - and some other properties we own. Their professionalism and honesty has always been top notch, and they are always 100% dedicated to figuring out exactly what the underlying problem is. We were having a problem with one of our units randomly shutting off and while we feared having to replace it, they came out two or three times and figured out a pretty complicated (to us) problem, offered multiple potential solutions, and fixed it immediately. Unequivocally recommend these guys!read more

Justin and his team were superb. They provided the most competitive quote, completed installation in a timely matter, and were easily reachable for questions. I replaced two units and the ducting in my crawl space; my utility bill dropped from $318 to $110. The upgrades will pay for themselves faster than I could have anticipated. Thank you!read more

This company has done a lot of work for me this past year. Buying a house that was sold to me with the promise of new HVAC and then finding out that it wasn't even up to code was pretty infuriating. But, Justin and his team corrected everything and installed a great system (and continue to provide excellent service!) I highly recommend them!read more

My shiny armored white knights! Krantz fixed the mess Love Plumbing left me with. Using a Manual J, the benefit of their experience, and common sense, Krantz crafted an HVAC system appropriate for my house. They even fabricated a new return duct in my driveway! Unlike Love Plumbing's visual pollution with their huge billboards, Krantz relies on word of mouth from satisfied customers to grow its business.read more

I have been a Krantz customer for many years, and they did their best to keep my old HVAC system in working order. This fall, the system developed a problem, which would have been too expensive to repair, and invest in a unit which needed to have other repairs. I chose to replace the system and all of my ancient ductwork at the same time. After an initial consultation with Justin Krantz, in which everything was explained to me, the Krantz team came in, and over the course of several days they removed the old unit and ductwork, and replaced everything. They did an incredible job, and finished after dark, the day before Thanksgiving. It was important to me to have a company I trusted to do this project, and with Krantz, I knew they would do a great job, and stand behind their work. I would highly recommend them.

Thank you Justin, Chad, Stephen and the crew at Krantz Cooling and heating. I shopped around but ending up going with my realtor's recommendation for a completed HVAC overhaul. New ducts, handler and condenser on our 1950s home. The crew stayed late one evening that was going to get very cold to make sure we had heat. No pressure sales to upsell me on a more expensive unit either. Thanks again!read more

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 needs.read 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 them.read 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

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 priced.read 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 services.read more
