Exceptional Air Conditioning Repair in Cary - Delta T NC HVAC Saves the Day!…read more I can't say enough good things about Delta T NC HVAC and their air conditioning repair services in Cary! When my 80-plus-year-old mom's AC stopped cooling on a hot June evening (Friday at 5 PM!), I was in a panic. Thankfully, Keith, the owner, personally answered my call--something you don't see often these days. Despite it being late on a Friday, he had a technician out the very next morning to assess the issue. They quickly discovered that the AC was leaking Freon too fast to be repaired and needed to be replaced. The new unit wouldn't arrive until Wednesday, but instead of leaving my mom without AC, they added enough Freon to keep her home comfortable until then. True to their word, first thing Wednesday morning, the Delta T team showed up on time and installed the new AC system that same day--no delays, no excuses, just excellent service. Their professionalism, responsiveness, and genuine care for their customers make Delta T NC HVAC the best choice for air conditioning repair in Cary. If you need reliable, fast, and expert HVAC service, don't hesitate to call Keith and his team!

I was pleased to learn that the newly installed part should last 7-10 years, as opposed to the factory part that usually lasts 5-7 years. In addition to replacing the needed part, Chris let me know about a different maintenance part that probably would need to be replaced within the next three years. Moreover, Chris informed me that our refrigerant looked great.

They came out immediately when I told them about the Carbon Monoxide monitor. They discovered a leak in our old furnace venting system and were able to fix it right away. We decided to replace our old furnace and put in a new HVAC system because family was coming to visit later that month. MTC was able to complete the job quickly and even came back to make sure the system was running well before our family arrived for their visit! We were thrilled with their work, and we highly recommend MTC Heating and Air! A new update: Yesterday, lightening struck a tree close to our house.

Here's a shorter, stronger version that stays focused on your firsthand experience:…read more Extremely disappointed with my experience with Cool Change. I purchased a new HVAC system expecting a professional inspection and honest recommendations. I was assured everything was satisfactory, but after installation I discovered significant ductwork problems, including conditioned air escaping into the crawl space and the system running almost continuously. There were also known circumstances involving the ductwork, including a disconnected bathroom vent from a 2023 renovation and a washing-machine leak in 2024. This raises serious concerns about whether the ductwork was properly inspected before the new system was installed. When I raised my concerns, the owner's response and treatment of me were extremely unprofessional. I expected transparency, accountability, and quality workmanship and unfortunately, that was not my experience. I strongly encourage anyone considering Cool Change to get an independent ductwork inspection and document everything before purchasing a new system. If you have experienced similar issues, please reach out. Together we can help chnge deception in business.

If you want to be sold unnecessary and overcharged service without fixing your AC's true problem,…read morehire this company. I made the mistake to hire this company last week to diagnose and repair my AC system which was cooling fine but intermittently turned itself off. Instead of completing a thorough diagnosis, the technician who was constantly micromanaged over the phone repeatedly push for approval of adding about 3 lbs of refrigerant, an evaporator coil cleaning, and a thermostat replacement. When I declined the refrigerant and cleaning because the unit was visibly clean and there was no clear evidence of needing refrigerant, the manager threw a tantrum over the phone and ordered complete of service. It costed $400+ to just replace a thermostat. I did not know that the performed thermostat replacement was not fixing the true problem, might not have been necessary, and it made the AC performance worse. After the technician left, my AC failed to cool the house and water started coming from the handler. The indoor blower continuing to run even when the thermostat was set to Off and the fan was set to Auto. I had to hire another contractor who quickly identified thermostat's WRONG WIRING and performed the needed repair. No refrigerant needed, no cleaning needed, just firming the connection of the disconnect box, less than $100. The system was running with all readings in range and completely balanced as soon as the new repair was done. What Icy Hot did was short-circuiting cooling and heating together in thermostat installation making the AC to run both cooling and heating at the same time! What a joke if a company cannot even install a thermostat correctly (not to mention it was probably unnecessary) and charges $400+ for a faulty installation. I wrote to Icy Hot noting the FAULTY service, the manager ACKNOWLEDGED the thermostat wiring was incorrect, but REFUSED to reimburse any costs despite their MALPRACTICE which could have cause further damage to my AC. Extremely disappointed with the incompetence, dishonesty, and the lack of accountability after their work created additional problems. Stay away!! [Additional notes given company's response below]: The company's response below shows again their insist of unnecessary service. The AC's issue was not related to refrigerant nor it needed any cleaning. The technician onsite was not able to show much evidence justifying either but was under immense pressure from the management to oversell. The service was scheduled from 3-5pm but the technician did not arrive way after 5pm and took an hour still no clue. A lot of the time was spent speaking on phone with the manager. The service was never an emergency service. I called in the morning, the office said they could dispatch a technician between 3-5pm and we set appointment. Categorizing the scheduled normal service as emergency and claimed to have stayed after hour to falsely induce mercy is just another evidence of dishonesty. Regarding the revisit to correct any error, I was reluctant to call the Icy Hot back given the incompetence and the oversell push during the initial visit, not even for the so-called warranty service. This echoes a review posted by another customer earlier in Google review. I worry that instead of fixing any error, more unnecessary service will be demanded and further damage be done to my AC. Now it is not hard for the company to say: Well, that was an easy error to correct, and you should have called us. This is all because another contractor with true expertise and good ethics has diagnosed Icy Hot's error. If Icy Hot was capable and ethical at the first place, the error would not have occurred with sufficient final steps of double checking wiring, temperature and air flow after thermostat installation. Aren't these necessary steps by trade standards?

While they were working, they explained they do a preventative maintenance program at a fair rate. I believe my wife and I will plan to sign up for that this year.
