HVAC FAQs

What is the SEER Rating?

The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the total rating.

Why should I have regular (or preventative) maintenance? And how often should I have it performed?

Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts. You should have maintenance completed on your system regularly to ensure maximum efficiency and prevent possible problems that may occur in the near future.

What equipment requires regular (or preventative) maintenance?

Heat pumps and air conditioners require a professional tune-up twice a year; in the spring and fall. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, and refrigerant lines.

I need help troubleshooting a problem with my equipment.

As your local Trane dealer, Krantz Kooling and Heating is your troubleshooting expert, and is glad to help you. In addition, Trane also provides a network of troubleshooting technicians at Trane Distribution centers across the country which Krantz Kooling and Heating will utilize to address your concern. Should we encounter a situation that requires additional factory help, we will contact our factory supported Service Manager(s) for assistance.

What are the advantages of a programmable thermostat?

Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

What type of filter should I use? And how often should I replace it?

Standard filters work to keep your system and its ductwork clean, but they don’t really improve indoor air quality. To do that you need a media air cleaner. The media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal up to seven times that of a standard filter. However, upgrading to a pleated media filter will remove everything from dust to airborne viruses from the filtered air. Always choose a filter that matches your blower’s capacity. For optimal efficiency and filtration, we recommend that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

Why can't I find the correct size furnace filter at my local home improvement store for my Trane Brand Equipment?

Filters for your Trane unit are made from higher-quality materials than those of the disposable filters found in retail stores. For that reason, replacement Trane filters can only be purchased through a Trane dealer. However, keep in mind that some Trane filters are reusable, and can be washed by hand in cold water.

Where can I get parts for my Trane equipment?

As a Trane dealer, we are the best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

Which Trane equipment will best fit my home?

There are many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. Krantz Kooling and Heating can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family’s needs. Depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to ensure the size of the system you purchase will be large enough to heat or cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional.

What does my warranty cover?

Under the standard factory warranty, Trane covers parts that fail during the warranty period due to defect in the part. The warranty does not cover labor. A warranty certificate was included with your homeowner information packet, and is specific to the model numbers, serial numbers and installation dates of your products.  All Trane equipment that we install is registered with Trane Corporation to ensure your 10 year parts warranty.  If you cannot find your warranty certificate, Krantz Kooling and Heating will also be able to provide you with that information. With a Krantz Kooling and Heating Total Comfort Plan, you’ll have a ten year parts and labor warranty on your Trane equipment.

What is the life expectancy of my unit?

Dependable Trane products are among the longest lasting heating and cooling products available. For your specific equipment, there are many variables that affect life expectancy, including, of course, the regularity of routine maintenance.

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
