Miguel was very thorough and patient, and explained what was going on and all of the options. Got the AC working again and set up a maintenance plan. Very reasonable pricing. Would highly recommend. read more

I called Nate over at Cool Dynamics because my AC just wasnt cooling anymore. That same day, Caleb and Miguel came out to take a look at the system and found a tripped breaker. They did an entire maintenance routine anyways and luckily nothing was broken elsewhere, just the breaker. While they are not electricians, it doesnt take one to see that it appears that the home builder under-specced the entire panel and they recommended I have a qualified electrician come out to take a look. No upsells, no sketchy recommendations, just good, honest service at a reasonable price. This is the kind of company you WANT to work with and exactly the reason I wont call anyone else if my system needs anything! Thank you Nate, Miguel and Caleb, youre the best!! read more

Nathaniel finished the install of our 2 brand new variable speed AC units. Very professional. Explained everything that would be done. Did a full assessment prior to giving quote. Explained all options. Obtained permits. Did a walk through afterwards. I've never been more impressed with an AC company. They are a newer business. The owner himself was part of install crew. The warranty they offer is top notch. I highly recommend this outstanding business. The came back immediately to help with a Wi-Fi connection issue for my thermostat. It was my router not the thermostat. Thank you So much! read more

Woke up to my AC unit not cooling on a Saturday morning. Called and they had a tech out within 2 hours. Miguel was the most professional and polite person that you could hope for. I am beyond impressed with their service, cost, and honesty. I decided to sign up for their monthly maintenance plan as they are a business I am happy to support. Thank you! read more

Cool Dynamics Heating and Cooling and Miguel Benevides- service technician were amazing in getting out for my semi annual inspection. Miguel was very professional and knowledgeable and thoroughly explained what he serviced. He provided me some options that may alleviate our high CPS bill. Miguel left a lasting impression on what excellent service is. 5 Stars is not enough when a company and their service technicians go above and beyond. Highly recommend Cool Dynamics for all you HVAC needs. Rene G read more

After many attempts to get other AC people out as soon as possible, I was able to schedule with them next day! The guy came out did a quick fix of my clogged drain line, told me about their maintenance options but didn't sell me, and it was an hour tops. This is who I will use in the future! Thank you! read more

Very nice young man came out .They responded quickly to our call. It was a very hot day for no AC. He fixed the problem we were having with our AC. read more

nate came out and diagnosed why our a/c wasnt cooling and why outside unit was going on and off. some other guys trying too sell us $4500 outside unit. nate said it was the water drainage line plug up and needed a flush only. he charged us a service call only and saved us thousand. a/c gets to set temperature hard to find honest people these days definitely will have him come if we have another issue. thanks man! read more

Cool Dynamics is a small company in a sea of competitors in San Antonio, but Cool Dynamics is OUTSTANDING! I'd recommend Nathanial and his team to my friends, family, coworkers--no contest, and every time. Our AC went out during 80-90 degree days in October. We'd been combatting a wide range of options spanning partial fixes for $4.5K to full overhauls for $12K. Nathanial himself came to our home, same day, after we called looking for a fourth quote. Nathanial was incredibly professional & respectful, knowledgeable, thorough on inspection, and honest about his assessment and our options. He was able to get his team out the next morning for an all-day install of both interior and exterior system upgrades. The quality of work his team completed was impeccable, and they were thorough in cleaning up the dust and work residue. He offered a 10-year warranty for parts, two year labor warranty, is coming out to inspect how the systems are performing after a week of use, and told us that a state rep would be out to inspect his work. Nathanial and the Cool Dynamics team is everything we needed: someone genuine and sincere helping us with an acceptable product that we needed in a time of need. I couldn't be more grateful for his professionalism and I'll continue to recommend to anyone who has a local need. read more

Unbelievable value! Will definitely use again! Met owner and technician and both were fine young men!

I needed my heat pump unit and mini split unit replace. Nathaniel came out to give me a estimate. He was very professional. He looked at what I had, asked about air flow in each room, tood me about 3 different new units available, went over pricing. I decided to go with them they showed up the next day and started work. It only took them 1 day they came back the next day to check on work everything was good. They had to order split air unit it came in a few days later and installed in 1 day. I won't name the other company I was considering going with but they offered a 10% senior citizen discount and I didn't see it on estimate I questioned them about it and they denied every overing the discount. If I can't trust a company I mark them off my list. Another thing the company I turned down was $10,000 more. read more

Very quick response. Was able to quickly diagnose and fix the problem with my a/c. Technician who came to help me was polite, respectful of me and my home and very pleasant to work with. Very fair price as well. I will definitely call on Cool Dynamics again should the need arise. Highly recommen! read more

There was a gremlin (1984 movie) in my unit that would hide, then show itself just when you thought the problem was solved. Nathaniel was persistent enough in his diagnosing to catch the gremlin (bad thermostat turning the air handler fan on and off sporadically) red handed. His service was prompt and professional. Nate isn't going to make up something to milk you like a cow for every dollar he can. I pray that his integrity stays intact and that God continues to bless him and his as he grows in the HVAC business. read more

Top service, great attitude, and a sense of wanting to help. After a diagnostic on my ac, Martin gave me full details on what to expect with my needed repairs including price and a timeline of when work would be done. Will call cool dynamics heating and cooling for any future ac work! read more

Okay, I usually hire people not only on ratings, but also how many ratings to know that the merchant is well established as well as experienced. Nathaniel not only knows what he is doing, but also has a professional demeanor and the best pricing. From start to finish you will get professional service with the best pricing around. Nathaniel even did our diagnostic for free as a way to show appreciation for my Dad who is a Vietnam Veteran on Memorial Day. Nathaniel, thank you for you professionalism and kindness towards our veterans. read more

Nathaniel came out today to see why my AC was not working. He did a thorough inspection of the inside and outside and found the problem. It was fixed in short order and is working great. I know my unit is over 20 years old so I asked for an estimate on replacing it. He gave me four different options and I was pleasantly surprised that they were less than expected. He also included any additional charges there might be if I wanted the ductwork replaced or if any wiring needed to be upgraded for a higher end model. he was not pushy or trying to get me to choose any particular model or even make a decision today. He explained the differences between each one so I feel like I can make an informed decision when the time comes. I would definitely recommend Nathaniel and his company for any AC or heating repairs or replacements. I believe he is forthright, honest and has integrity. read more

Nathaniel Segura came out and greeted me with a handshake and a smile. Professional and efficient from start to finish. Nathaniel quickly diagnosed the problem on my outside unit and had my family cooling down in this Texas heat. Thank you for taking the time to thoroughly explain the issue and the diagnosis. Your honesty and respect have earned my business. read more
