I had a concern about water appearing at the bottom of my gas pack. David came out, explained what was causing the condensation, even removing the panels to show me what was happening. He was very personable and answered all my questions. read more

We are very pleased with their replacement of our old gas pack. We had five companies to give us quotes. They were the only one who suggested measuring our house to see if our system size was right for our house. As it turned out, a 2.5 ton was more appropriate than the 3 ton we had been using. Their prices were competitive. The installers were professional and did a good job. I liked that their office filed our warranty papers and applied for Duke Energy credit that we qualified for. No one else mentioned the Duke Energy credit. read more

From start to finish, excellence every step of the way. Andrew came out to look at my 26 year old AC system which had started to leak coolant, and recommend what to buy next. Integrity sums up his style. Fully honest about pros and cons. He continued to stay in touch and follow up for what comes next. The unit was installed in December and he has planned for a spring visit to turn it on the first time. Thank you Andrew. Jose and Mehmet installed my new AC. TOP NOTCH. On time, polite, courteous, extremely professional, the job done correctly from start to finish. Even came out the next day to put the finishing touch on something. Thank you Jose and Mehmet. Communication with this company is on the spot and prompt. They let you know what time the technicians are coming and also what their names are. Quality of service, and integrity, are outstanding. read more

Klimatology HVAC - Heating & Air Conditioning/HVAC Near Me - Morrisville, North Carolina

Gave me an accurate evaluation of my Hvac issues. I was given a detailed explanation of what needed to be done to correct problem.

The technicians were very thorough, prompt, and experienced. They explained the charges well and the need for the replacement parts and my HVAC system. read more

Had a good experience with klimatology, Zach diagnosed the problem and we got a solution worked out with minimal obstacles. And the scheduler was very receptive to a unique unforeseen circumstance. I would recommend them and look forward to using them again read more

The tech arrived unprepared for my request. I asked for a tech familiar with a PTAC heat pump and to charge it with 410a coolant. I got neither. Rather I was told what I already knew. The unit needed coolant and probably has a minor leak. So $80 for nothing. The people who manage and dispatch are at fault, not the tech. No I would not recommend this company read more

The team did a great job installing our new HVAC system. The price was fair and the communication was solid throughout. They explained everything with our new system thoroughly and it's all working like clockwork. Thanks so much for your help and great work! read more

I didn't get past the initial phone call. I told them I needed a central hvac system replaced, and I needed a quote on a new unit. I had the heating and cooling capacities that I needed. They said there was a $75 diagnostic fee. I said I didn't need a diagnostic performed, I needed a quote for a replacement unit. They said the diagnostic fee was mandatory. End of call. Sounds like a jobber that sends out independent contractors for work. Not what I needed. read more

They were great. They provided lots of options, answered my questions and gave me the best price. The installers were efficient and courteous. I couldn't be happier. read more

Wonderful experience all around... from scheduling, to the technician identifying the issue and fixing the unit. Very respectful to my property, very polite.... easy to pay. They showed up within the timeframe that was communicated to me. As I said before a wonderful experience, all around we will be using them again in the future!! Highly recommend. read more

My heat went out on a Saturday and Klimatology came out right away even though I'm in Carrboro. They wound up fixing my HVAC so well that it seems better than ever. I'm very grateful to you Klimatology! read more

Our old boiler/radiant heat system was banging last season and before we could turn on the heat this year, we knew we had to have it checked out. Andrew, a Midwest transplant like us, was familiar with boilers and made a valiant attempt to repair ours. Unfortunately, during the course of soldering copper pipes, a series of leaks sprung up, making further repairs a waste of money... He suggested routing a gas line to our Central AC Unit outdoors because he said it had a heat pump that would do the job of heating our house. That worked!!! It feels SO good to have heat again! It took three trips to get to a final solution and we were worried about the cost, but Andrew came up with a very fair price. I can't speak highly enough about the integrity of his service!! read more

We had a number of contractors come out to give us a quote. Andrew is very knowledgeable and his integrity is impeccable. He didn't hesitate to tell us about more affordable options than we were previously considering, even when they would make less money for Klimatology. He took many more measurements and was far more thorough than other estimators that came out. We asked all the contractors if they would be doing a Manual J calculation of our load needs based on the unique particulars of our house (old house but we've done a lot of energy efficiency retrofits) so that we don't end up with short AC cycles and high humidity in the summer time (a current problem for us). Some contractors said they rely on a rule of thumb for right-sizing. Others said they would use software to make a calculation but took no measurements. When we asked Andrew about Manual J calcs, he is the only who said "of course, we always do that". He was the only one that took all the measurements necessary to do a full Manual J calculation. With Andrew's assistance, we came up with a stop-gap solution that will allow us to put off the HVAC upgrade until new Federal incentives come into effect next year. So, we haven't experienced Klimatology's installation work, yet, but based on Andrew's work, we will definitely be calling them in the new year. read more

Called for HVAC (AC) not working. Very professional and showed up on time. Clearly explained what they were doing. Luckily it was a minor fix and I was charged only for consultation. Highly recommend. read more

Seasonal maintenance check/service. Offered multiple time-slot options to suit my schedule. They provided real-time updates on their arrival time and arrived within 5mins of the originally scheduled time (that just hasn't happened with other service providers). Technician was thorough and provided details of what they were doing and what they found/recommended. No upselling...just clear honest feedback. Very courteous and kind technician. Good value in comparison to other companies I researched. read more

15-year 2nd floor A/C stopped working (ran out of refrigerant). Very thorough/transparent on their estimate and answering any questions I had. They did a full calculation to determine the existing furnace/AC was severely oversized. Installation was smooth. Will use them for maintenance and future replacements going forward read more

They responded and came to my home the same day I contacted them. The technician was knowledgeable and was even kind enough to explain to me what my issue was, as well as providing tips on how to prevent. I will be using them for my HVAC issues or maintenance moving forward! read more

We were in need of an estimate for a HVAC replacement system. They were very prompt in sending Andrew over . I cannot say enough great things about his professionalism and knowledge . We got a very competitive quote the same afternoon and install completed two days later . Andrew communicated with us throughout the whole process and made sure he personally checked the work done and came up with a better , eye pleasing solution to securing our gas lines . We would use them again if needed , and definitely recommend them as a business . read more

Klimatology HVAC - New system. Dog is ours , lol! - Heating & Air Conditioning/HVAC Near Me - Morrisville, North Carolina

Our a/c stopped working on a Friday night and Klimatology was at my house on Saturday morning at 7:50am. They were able to fix the a/c before 10am! I am so grateful! read more

THIS is the company you want. Carlos came out to our two-story house and diagnosed heating issues. While the ducting wasn't properly installed when the house was built, he was able to make some adjustments and make the temperature SO much more comfortable. Professional, friendly, good communication...everything you want in a service person coming to your home. He showed us photos of the issues and discussed next steps. Sadly this is not the kind of thing we're used to. Previously, we had a $300+ conversation with another guy who stuck his head in the attic, did nothing, and said we needed to drop over $2k for a zoning system. We're customers now because of Carlos. read more

I hired Klimatology HVAC for a heating repair work today. I called yesterday, told them it's a rental property and left my phone and email. Until noon today I didn't get their update on the issue or talk about repair price. I called them instead and was told the problem was fixed (which I really appreciate) and invoice would be sent shortly. Be aware that if you won't be at the property during repair, you might be charged whatever. read more

While they are costly and charge a service fee each time they come out, and it's not taken off the repair cost; they get the job done.

Nihat Yucel...the owner came out to diagnose an a/c problem we were having. He was very prompt...thorough and professional. He took his time and explained everything to us. We are very happy that we found this company...we cannot say enough good things. Thanks so much!! read more

Great price and service. Nihat and 2 other guys installed a complete HVAC system in my daughter's townhouse in about 6 hours. Bryant system with Honeywell dampers for thousands less than I expected. Very professional and respectful of the property. The system has only been installed for a couple of months, but everything is working great so far, and passed inspection no problem. These guys are honest hard workers. A diamond in the rough. read more

Nihat & Janice are the best! As a first time homeowner, figuring out anything house-repair related is daunting - these guys have helped us out with AC issues a couple of times now, and always seem honest and dependable. Definitely recommended for HVAC service in Durham. read more

We received great fast service from the owner operator. I highly recommend for ur HVAC service.

It had been quite a while since any preventive maintenance had been done on our two heat pumps. Nihat responded quickly to our call and was able to come out right away. He caught current and potential issues and corrected an installation error that no other service people had spotted since the air handler had been installed 25 years ago. Nihat was focused, efficient, and businesslike, but friendly and communicative. read more

Stop. Don't keep looking. You've found the HVAC company you want to hire. Yes, I'm a real person. No, I haven't been incentivized in anyway to write this review and, no, I had no prior knowledge of or relationship with this company. Nihat Yucel (Owner) and his small team are the service providers you hope to find. When someone you know needs HVAC work done, this is the company you'll jump to say "Hey, you gotta go to my guy". Since we moved into our home, I'd done the regular maintenance on our two HVAC units. Both units were on the older side, so they needed tender love and care. Well, this year I was convinced against my better judgement to delegate the work to a "professional". I ended up hiring one of these larger companies you've probably seen a commercial for and, wow, I could not have made a bigger mistake. They sent a kid out that was so young he could have been a fetus, who didn't perform any of the tasks outlined in their maintenance, couldn't answer basic questions and didn't look like he'd ever seen a multimeter before, tried all kinds of shady up-sells, and then ultimately caused my compressor to blow a terminal beyond repair. My unit was toast, that company was the type of garbage that makes everyone resent having to hire someone so there was no use reaching back out to them. And so, of course I had to start looking for another company to replace both of my units immediately since it only made sense to replace both with age as a factor and since we were on the verge of 90º weather everyday. In total, I'd reached out to 6 different HVAC companies. Every single one of them gave us replacement costs that were, no exaggeration, $4K-$5K more expensive than what Yucel and Klimatology gave us. On top of that, all of them followed suite in their up-sell practices and shady talk that made you uncomfortable making a decision. Klimatology literally felt like a godsend and completely took the stress out of an issue that is extremely stressful.ucel came out promptly the next day or two after I'd called in, plainly asked me what I was looking for help with instead of giving me a "good, better, best" BS diagnoses and sales pitch, and then sent me the best quote we received on the HVAC brand we actually wanted with no frills or up-selling attached. I wish I had more characters available in this review to give you even more details into how great of an experience this was, but I don't, so I'll try to summarize the rest here shortly. Not only was Yucel amazing, but every single one of his employees were courteous, extremely professional, extremely patient, extremely knowledgeable, truly cared about the quality of their work, and did an amazing job. They installed two units very well in all of 4-6 hours. When I went to inspect the work, they even did things that weren't outlined in the job or even required, like sealing holes or gaps in my ductwork where they saw them, painting my gas line, etc. I can't say enough about them. Yucel came by later that day to inspect the work himself and collect payment. He and I had time to talk and he admitted to me that he has purposefully kept his team and company on the smaller side, one, so that he could keep the overhead low and pass on the savings to his customers and two, so that he can ensure the work is consistent and high quality. I would 100% say that is the experience that I had and I would truly bet money that I would NOT have had that experience with any of the other companies I had come out, all of whom were much larger than Klimatology. Furthermore, there are the intangibles that you really can't sell or put a price on. What I mean by this is character. Yucel, and his team, all had great personal and professional character. At one point, after Yucel knew the money was in the bank for the work, he stopped me to tell me that "HVAC's are very complicated systems. I hope nothing will go wrong, but if anything goes wrong, please don't be upset, just give us a call and we will come out immediately to fix it." That, to me, was the icing on the cake in terms of solidifying the good impression I already had of Yucel and his team. HVAC's are very intricate systems. I know because I took care of ours for years. I looked Yucel in the eye and told him that, after the experience we had with them, the units could catch fire tonight and I wouldn't be upset. 2 weeks later and they're running amazingly. All of the caulking and detailed work are holding up fantastically. Using Klimatology for your HVAC needs is a bulletproof decision on a service that's really tough to feel confident about. read more

A very responsive group. Came out quickly and solved our issues. Tech communicated everything very well and had a great demeanor about him. We will definitely call on them again when we need help. read more

They come to replace my broken thermostat. Very professional and kind. Price is reasonable. I will definitely consider them if I need to update or maintain my HVAC system. read more

I can't recommend this company highly enough! I submitted a request this morning after waking up and realizing I was freezing and therefore our heat was clearly not working. I placed an inquiry with several companies on Yelp. Klimatology was the only one to respond immediately with an appointment offer for 10:30am same day service. I accepted the appointment. Nihat (owner) came out right at 10:30, fixed our unit efficiently and affordably and was very nice to talk to. He was kind enough to check on a potential warranty for our unit which allowed us to save money too! Super grateful for their great service and glad all of my kids will have a comfy cozy house to fall asleep in tonight read more

Klimatology was amazing to work with. Starting from the consultation to the end results. Nihat and Jose were incredibly professional, punctual, and knowledgeable. We needed to add a gas line to a new pool heater and they gave an reasonable price, they were on time and finished the project ahead of schedule. They were great about keeping us up to date on their progress. I would highly recommend Klimatology for any of your HVAC needs. read more

They were great! Goodmon went the extra mile to help us out and gave advice on how to avoid the issue in the future and for a very fair price. I definitely trust Klimatology way more than past technicians from other companies who overcharge and still not manage to fix the problem. read more

Really great experience with this company. Nihat was great. My A/C unit would not start. I couldn't figure out what the problem was. I scheduled an appointment with Janice just texting and it was confirmed. Nihat came on time and wore a mask. He was quick, efficient, and honest at a good value cost. He was friendly and informative. I will definitely use them again. Thank you klimatology read more

Had a great experience with Klimatology. Fast, great value, did good work, easy to work with.
