Client Testimonials

"Nick has now repaired 2 boilers for more, the first on NY eve, when no one else would even answer! Thank you, Nick! And to the rest of you reading: if you need a HVAC repair, call Nick first. It will be the only call you will need to make."

"I lost my heat, and it was 15 degrees that morning! Nick was able to come out the same day. He was on time, professional, found the problem quickly, and was able to make the repair immediately - he had the part in his truck. And like someone else commented - great sense of humor. That's always helpful for dealing with "issues." Highly recommend Nick and Cool Ducts. Hope American Home Warranty sends him my way again!"

"Nick came by after we submitted a warranty ticket. The warranty didn't actually cover what we submitted for, but Nick was kind enough to help us out anyway! We really appreciate his knowledge and generosity on the matter and hope that you'll consider him for your future AC and Heating needs."

"When my heater went out, Nick was available to come by the very next day. He was extremely professional and easy to talk to. He fixed the problem almost immediately, and my heat came right back on. I would highly recommend Nick, and will surely be giving him a call next time I have any issues."

"Nick is the man. He installed a whole house humidifier and a nest thermostat for my wife and I in a house we just purchased. He was professional, easy to contact (calls and texts), and punctual. He gave us plenty of options, reasonable prices, and indicated potential problems with existing work. We'll 100% call him again for any future needs."

"Nick was extremely helpful troubleshooting our furnace. He was easy to work with and got our replacement parts ordered through our warranty quickly. He went above and beyond to assist us. We will absolutely use Cool Ducts for any future needs."

"Nick was great when our heater went out this week! He was easy to get ahold of when we needed him and able to work around my work schedule. He found the part needed to fix our unit and made sure we were well taken care of! We will definitely continue to use Cool Ducts for any future needs!"

"Nick was great! I really appreciated his prompt, quick service. Even though I screwed up and tried to change out the thermostat myself, he repaired everything with a smile! We plan on using him in the near future for general maintenance of our heating and A/C units. Not only do we appreciate that Nick has a locally owned business, we also appreciate his professionalism!"

"Highly recommend Nick. We called him out for our furnace not working, he was prompt, friendly, professional and got our furnace back up and running in no time."

"My experience with this company was great. Prompt service. Very respectful and was available next day. My AC is blasting again. Thanks Nick. I give my highest of recommendation for this company."

"Nick was great and very professional to work with. I had my routine annual A/C tune up done by a National HVAC chain who said my compressor was seized and the whole unit needed to be replaced. Nick came by the very next day and in about 5 minutes using a $20 part my A/C was working again good as new. I will definitely use Cool Ducts again for any heating and cooling services."

"Nick was very personable as well as extremely professional. He worked to get my furnace up and running quickly while saving me money by staying within my appliance warranty."

"We got to use Cool Ducts through our warranty company. Best choice ever. Technician - Nick, he was very helpful. He understands customer's "pain", like our AC went out during 90 degrees temperature for 2 weeks. As soon as he got the part, he came out to SAVE OUR DAY after his dinner. You can't get a better technician than Nick!! Hire them, you will not regret."

"Very professional, arrived on time and fixed our furnace when another company incorrectly quoted us. Highly recommended!"

"Nick was on time and fixed my heater that was not working right. He was very helpful explaining what he did to fix it worked around my schedule and even talked to my nephew about the HVAC Field I would highly recommend Cool Ducts for your heating and cooling needs!"

"Knowledgeable, fast, professional. Came to my house same day, figured out the problem and fixed in less than an hour. This is how HVAC servicing (and ideally all home services) should be. Thanks Nick!"

"Service was great. Went above and beyond to work with the home warranty. Was available much sooner than the first company the warranty people sent our way. Highly recommend."

"Nick responded to my call today WHILE he was in a crawl space. Our furnace had stopped working, and he came out very quickly, fixed it, and got our house warm again. He also gave us some tips for if anything goes wrong in the future, and walked us through something that could cause an issue in the future if not fixed. I am so grateful, and will certainly be using Nick again in the future if anything comes up."

"Very knowledgeable, seasoned professional and a positive personality. I will use Cool Ducts again!"

"Cool Ducts is a wonderful company! Not only is Nick friendly, but he is very professional and does great work. He is very knowledgeable in his work, and took time to explain what needed repaired. I was extremely impressed and happy with what Cool Ducts did for my home. You will be very pleased with Nick's work. Please choose Cool Ducts for your heating/cooling needs!"

"Nick was very responsive and highly experienced which showed in the quality of work. I will be calling Nick at cool ducts for any of my heating and cooling needs."

"We had issues with our house humidifier not shutting off. Nick identified and fixed the problem quickly. While working, he also shared his knowledge on all things related to furnaces and hvac systems, giving us recommendations on relative cheap things we could do to improve efficiency. I recommend Cool Ducts for any and all hvac needs."

"Nick was super helpful and knowledgeable. He wore a mask at all times and removed his shoes which I really appreciate because I have a crawling baby and it’s important to me to keep my carpets clean. He show me what went wrong with my heating system and he showed me how I can fix it next time it happens. I highly recommend!!"

"We were in a jam, and Nick really came through for us. He's friendly and an honest communicater. The quote was much lower than I expected, and the job was expertly completed. I also liked how Nick picked up his phone after just one ring (I called after hours). Many thanks!"

"I was so impressed with the quick response I received from Nick at Cool Ducts when I reached out to my insurance company requesting service because I had no heat in my home. He contacted me that Sunday afternoon, promptly diagnosed the problem, and provided a temporary fix while the required part was ordered. He went above and beyond to get my furnace repaired and did so in a very timely manner. I would highly recommend Cool Ducts for your HVAC needs."

"Nick was really responsive and went out of his way to ensure our family had heat as soon as possible. He drove really far out of his way to get parts so the job would be done in a day. Thanks!."

"I worked with Nicholas to install a humidifier in my new home. He was ALWAYS on time. Always came prepared with information and communicated with me in a way I could understand. He came back to tweak a few things and since then my house has been great! I would hire him again in a heartbeat."

"My furnace was broken and the weather report was calling for sub 30 degree temps in two days. Nick was responsive, helpful, showed up on time, and fixed the problem. I was thrilled with the work and relieved that my pipes aren't going to freeze."

"Our warranty company sent us Nick to evaluate our AC that wasn’t working. He determined it had died & we needed a new one. He offered us a great deal on a new furnace so we went ahead & replaced both. He got the parts quickly & came to install them as soon as I was available. Definitely recommend Cool Ducts! Great service!."

"Nick was not only respectful of my home by wearing shoe covers, his knowledge to diagnose the problem and fix it quick while having the necessary parts on hand was beyond the best service I have received from this industry. He went above and beyond to answer my questions and was extremely friendly. I will be using and referring Cool Ducts (Nick) often!"

"Nicholas was friendly, courteous and knowledgeable. He fixed our system quickly. We had been waiting on another contractor without heat for 2.5 weeks. Cool Ducts was on site in less than an hour after contacted! We’ll be back!"

"Nick is personable, professional, efficient, and prompt. He cares that good service is provided. I really appreciated his help."

"I would highly recommend this company. They came out and did an excellent job. Fair pricing, knowledgeable, on time and so much more. I will definitely use them for all my needs in the future. There are so many companies out there. I Support local businesses who know how to do things right. So happy with my decision to use them 😊👍👍👍"

"Nick came and replaced our faulty thermostat the same day that we called! He kept me updated on his arrival time and was very communicative. He took the time to explain how to use the thermostat, and even went in to our crawl space to check on the furnace for me, and made sure that our filters were properly installed and that the furnace was running correctly. We have a dramatic furnace that has needed several repairs and we will not be using anyone else but Cool Ducts from now on, they are the best. Look no further, you have found your new go-to HVAC Service pros."

"Nick has serviced our A/C, installed our thermostat, and now replaced our furnace and he's been exceptional everytime! Super easy to communicate with, very knowledgeable, and works fast. Highly recommend!"

"Nick is a great guy and responded supremely fast. Troubleshooted and solved my issue in no way time. Highly recommend"
