HVAC reviews in Knightdale, North Carolina

We have relied on Air Essentials since I first owned a home fresh out of college and Jay and his crew have always been reliable, dependable, trustworthy and knowledgeable. They work smart and always look out for their customers!!! Thank you all so much!!!

Jay was awesome! He was very friendly and concise about the issues with our AC unit. I am very pleased with the excellent customer service Patricia provided as well. We will most definitely use Air Essentials services again!

Got appointment same day, Jay was awesome, super knowledgeable and taught me a lot about my HVAC system and helped me figure out the issue without having to get any work done to the system yet which shows integrity in my opinion. Will be calling them if I have further issues down the line.

Air essentials were absolutely Amazing. I called at 1pm about my AC, they were able to fit me in by 3pm. Jay knew exactly what was going on, while he was here he checked the entire system and provided feedback. Patricia who answered the phone was lovely. I could have talked to her all day. Such a great company!

I am so pleased with Air Essentials. The lady I spoke to the on phone actually CARED that my AC was out in the peak of summer with my 1yr old. She even had me turn my unit off for a few hours to see if it needed to thaw, and that’s before anyone ever even came by. She set an appt with me for 4-6pm but told me high chance that she could get me in earlier. I got a call soon after saying someone could come to the house right now (10am). The gentleman who came by was so kind and sweet. He even showed me some things. He was inclusive with me in what he was doing and looking for. He gave me options + his recommendations. Luckily we chose to do the Freon leak test because we ended up having a massive leak in the unit in the attic. He said that by adding just Freon (which is not cheap) that it would’ve last us maybe 3 days. A waste of $! So now I need to get the whole thing replaced but it was a lot lower than what we were expecting to pay. I appreciate this company, their staff members, and their service. Thank you!

We had a great experience with Air Essentials, Inc! My wife and I were experiencing issues with our unit not fully heating the house. I called in for service on a Tuesday morning, explained the issue, and had working heat by the early afternoon! Jay was awesome and extremely knowledgeable ! He even took time to explain the issue and things to keep an eye on for future maintenance.

Fantastic service and we will definitely be using them again in the future for our HVAC needs!

Air Essentials just saved me 10k! Jay correctly diagnosed (and fixed) a unit that a previous HVAC contractor stated MUST be replaced. Not sure if the other company was malicious or just incompetent. Either way, it’s good to know people like Jay know their job, and know it well!

Thank God for Air Essentials... They are life savers! They were there super fast and had us up and running in no time! Thank you all for the wonderful service!

I am very please with Air Essentials and the work they put into diagnosing our issues. Jay was very knowledgeable and super informative on our issues at hand. Super friendly and helpful. Thank you for your services!

Update: Our system continues to fail repeatedly. Today on January 20th, 2026 our heat won't turn on. Contacted Air Essentials with no response.

We hired Air Essentials in August 2025 to install a brand-new Trane HVAC system in our home, and it has been nothing but problems ever since. We went with this company only because they were available to install on a Sunday during a heatwave when our old system had completely failed. Unfortunately, we regret that decision.

They only arrived around 11 a.m. and didn’t finish until nearly 1 a.m. the next morning, working in the dark with flashlights. The owner only had two workers, and the attic was hot by the time they started, so much of the work was done under rushed and uncomfortable conditions without an opportunity to take turns between crews. The owner even admitted he arrived late because he “couldn’t wake up his guys.” They required full payment that same day by certified check before leaving.

That morning, the system failed — the air conditioner would not stop running and brought the temperature down to the 60s overnight. When we reported it, the owner told us to “schedule an appointment,” despite the system being brand new. Only after insisting did he return and spend several hours fixing it, saying there was an issue with the wiring. The very next night, it failed again — this time the system would not turn on at all after the thermostats were sending a clear signal to the system (click). Once again, multiple hours were spent troubleshooting, and the problem was traced to the wrongful wiring.

A few weeks later, we discovered standing water in the drain pan under the unit. The system was leaking. That required yet another service visit. Then we noticed significant cold air blowing in the attic while the AC was running — meaning air was leaking from somewhere in the ducts. When the owner finally came back, (after yet another attempt to brush us off)he admitted that some joints were not taped correctly and spent several hours re-taping connections.

Even then, there was confusion about one of the PVC pipes — whether it was supposed to be capped or open. The owner capped it, then uncapped it after we questioned him, saying he wasn’t sure which way it should be. To this day, we still don’t know if it’s in the correct configuration or if this could affect the system’s long-term performance. The owner admitted he is not Trane certified.

In total, within two months we’ve had five service visits (including install) for a brand-new system — each one taking several hours and requiring us to take time off work. The installation caused visible damage to the attic access panel, which now needs repainting, and the attic was left dirty after the first installation.
This has been an exhausting and costly experience. For anyone considering Air Essentials, we strongly recommend researching carefully and ensuring proper documentation of all work. Based on our experience, we would not hire this company again. It has been a complete nightmare to us.

I am a property manager and TRG services my community a lot for our HVAC needs. Joseph Herod aka Joe is my main point of contact and such a breeze to work with. Any time I reach out to him, I get an immediate response. His level of professionalism, timeliness, and communication is what makes our partnership seamless. Thank you TRG and Joe for all you do and have done!

I have been super happy with Triangle Repair Group. I received their information from a friend of mine, after I told him that my air conditioning wasn't cooling.

I requested an appointment through TRG's website. Alex called me promptly and scheduled a service tech to come out and take a look. The tech, Paul, quickly identified the issue (a leaking evap coil on my 2.5-ton Rheem package furnace A/C), showed me what it was, and asked if he could follow up that afternoon with a quote. Paul was terrific and explained things at an appropriate pace.

Alex followed up with a quote. Turns out the part was covered under warranty, so the cost was less than I thought it would be. I was due to be out of town, but since everything on this HVAC is outside the house, they were able to do the repair while I was gone.

Because I'm nosy, when I came back, I opened up our HVAC and checked out Paul's work. EXEMPLARY. I mean, also it was able to cool the house again, so that would be evidence enough for a normal person.

I was very pleased with TRG, Paul, and Alex, and I look forward to using them again when I need repairs or a new system... though, obviously, I hope I don't need either anytime soon.

Triangle Repair Group has stellar customer service. We have used them several times, they respond quickly and do an amazing job. I never plan to search for another HVAC company! It is refreshing to get such great customer care!

Brandon Stancil was wonderful to work with - we were experiencing no A/C during some of the hottest weeks of summer and he quickly came out and efficiently saw the problems. It’s an older unit. Thank you Brandon and TRG! We’ve worked with them for years and have always been pleased. I certainly recommend this HVAC company!

Scottie came to my home and presented two options for my 25-year-old HVAC systems, both of which were reasonable and accompanied by detailed, professional pros and cons. Antonio and Edgar then installed the HVAC systems based on our selection, at our convenient time. They were very honest, attentive, professional, and friendly throughout the process. They took care to protect all working areas, ensuring that all units, parts, drainage, supply, and returning pipes were installed and connected reliably. After completing the entire project, they cleaned up all debris. Overall, their service was wonderful, and we are highly satisfied with the results. Additionally, their charges were very reasonable.

Brandon S, my technician, was polite, friendly and got the job done quickly. It was fall maintenance on my heat pump and he gave me an A-Okay when he was finished. He also assisted me by replacing the air return filters inside the house. I appreciated his extra help. Thank you, Brandon.

Brandon was awesome. He’s super detailed, knowledgeable, friendly and professional!

He was able to find the issue when it had eluded others.

This guy’s a rock star at TRG. 🎸

FAST, FAST, FAST, Our technician Paul, got to my house and found my problem within 10 mins and had my unit back running in 15 mins. Best service ever! Thanks as well to Brandon who took our call to report the problem. Would highly recommend.

What a great bunch of individuals! From Robert initially coming to the rescue in short notice and Brandon resolving another issue on outside of the unit, we are back up in running with the expertise and superior customer care! It is great to have such an amazing company with quality employees who care for those customers! Thank you very much to Mary Beth in the office taking good care of people! I will certainly call again with any other needs!!

Got referred to TRG through a family friend after getting overpriced quotes from two other companies and wish I would have known about them sooner. I texted Brandon about my issue and he called me immediately to set up an appointment. He was very responsive and transparent about everything throughout the process. The service was great and my AC runs like new again thanks to TRG. I would recommend TRG for all your HVAC issues over the companies you see on tv!

After being without AC for nearly a month, my landlord, FINALLY hired Triangle Repair Group to fix our AC unit. We had to reschedule it at first due to the tropical storm. Triangle Repair Group was very understanding of our situation and how long we have already been waiting so they made sure to get us on the books ASAP. There was a hiccup in communication but it was quickly resolved. The technicians worked really hard at making sure they got our AC issues resolved that day. The owner came out as well just to make sure everything was in working order since we had gone so long without. Everyone was professional and friendly. 10/10 recommend
