The first technician that was  sent out by JT Dunn Climate Control   said that the  unit could be repaired that the unit need new coils etc  .  I  called the office of JT Dunn to ask how  could the tech do a proper assessment  because when he came out I  was not at home and he had no way  access to the inside  of the home to do a full assessment of the ac unit.   They assured me that it was an accurate diagnoses' moving forward  I was given an estimate  of roughly $1100.00  I contacted  JT Dunn about a week and a half later to  request to have the  work done. when the tech it was a complete  different tech  after he looked over the unit he said ha the unit really needed to be replaced and he proceeded to  contact his office  manager  Kathy  she proceeded to say  previous tech  Scott was no longer with the  company  and that the unit  would need to be repaired  as stated  by the previous tech.  I spoke with Kathy and the tech to let them no my concerns that I  wanted to the best  out come and I don't want to just  throw my money away  because if the unit  really needs to be replaced I  would rather spend my  money towards  replacing than repairing.  I trusted this  company Jt Dunn  and its employees  because this is not my area of expertise. The tech completed  the  work  and I gave the tech my credit  card number and  signed my invoice.   Needles  to say the  tech proceed to make repairs to the coil on the ac unit,  1 week later the  ac unit froze  up and the lines that the tech was supposed to had replaced  were leaking.    I  called my home warranty company in turn  sent out another  company  that  assessed the unit and said that the  coils leaking  and the unit freezing up  caused  further damage and the unit would need to be replaced.      I also received  a  call from Capital stating that  there  were  fraudulent charges to  my account  this  was 3 and half weeks after the  so called repair from JT Dunn I  had Capital one check all my charges for  JT Dunn  but they said that the transactions was never  put  through  by the merchant  JT Dunn.  I was in the process of applying for a home HQ loan  I was informed right before  closing that JT dunn and placed a lien on my home.. I was infuriated  because I am still enduring the blacklashes of this company. JT Dunn placed a lien on my home for$1300.00  dollars within less of a month of the service call.  I called their office and spoke with Kathy  the office manager  and asked why was I not notified  of them  placing a lien on my  I never received an  invoice or phone call, what kind of company places a lien on someones  home  in less than  30 days of service without making any effort to contact the  customer.  however I paid that $1300  fee to the court when I received copies of the documentation that had been  submitted to the  court , I was once again in ragged and disappointed because  JT Dunn had had additional  findings and suggestions to the invoice after they had given me my copy ( FRAUD). Per Kathy the lien  would be lifted with the paper work she gave me ..needless to  say it was lifted because the paperwork she gave  me  was not a legal document , in the mean time  my closing  was set back and every time I would call Kathy  about getting  the right documentation  she  would take my calls or  call back.  I  filed a complaint with the better I was then  contacted  by the owner Brett  initial he apologized and  said that he wanted to make this right and he  agreed to refund me my money  if I would retract my statement with the better business. I informed him I had no problem adding to my statement that he corrected the issues as long as he kept his word. Brett  told me that  he would mail it out and I should have it in a few days.. They money never came when  I contacted him he basically told me that he changed his I should have called his company back to fix the issues I informed him that  all that had transpired I was no-longer comfortable  with using his company.  I feel that JT Dunn took complete advantage of my lack  of knowledge as a consumer and then the owner himself refused to owner his own  words or even correct the  mistakes of his employees ...what kind of company holds the the consumer accountable for what the  employees are paid and  trained to know. I trusted this  company and this was a complete nightmare I paid them $1300 for a ac unit that ran for about a  week ...The  worst part of it all was the the owner Brett not keeping his word or taking ownership for his employees.
Response from Dunn Plumbing, Heating and Air Conditioning / Dunn One Hour Heating and Air Cond
"We are sorry you feel this way. We would've been ripping you off just to sell you the new AC and not fix your old one. The BBB agrees and heads of MO state agree we made a very good effort to take care of you. The decision on repair vs replace for an AC is never black and white so where one owner or tech could say replace the AC and another says fix the AC they both can be right. In your case the repair worked fine and just needed another tweak to the king valve which we would've done for free if necessary. We value customer service - We could've saved you thousands but you didn't call us back to honor the agreement you signed. Our offer still stands to credit you back the money toward a new AC if that is what you want."

Timely service with really nice people.  I love getting rid of the dry air and static.  I called these guys for a different problem after hours and they arrived on time the next day and fixed my issue.  They'll be my new "go to" furnace and AC folks in the future.

"Hello [Member Name Removed], Thanks so much for your business. I appreciate you saying the serviceman was very professional so I am curious if he really gets a 'D' for professionalism.. Our hope is that the D was accidentally typed in but if not we would like to follow up to ensure 100% customer satisfaction."

I called earlier to launch a complaint against Dunn Heating & Cooling. They gave me the run around. I them and asked them to come and take the furnace out of my house that they put in last Friday because, they did not honor their ad. They did a bait and switch that I didn't appreciate. I paid $1495 for the deal that they did. The guy came out and gave my husband a lot of salesman bull. He didn't bring out any brochures for the Ream deal. He pushed the Tran system on him. He figure that because, our furnace has been flagged three times. They would not turn it off. I'm not happy with the deal at all. I'm asking for a refund and I put a stop payment on the check. I call him to come back out and I told him that I needed some vents put in upstairs. He is trying to build a Mitsubishi unit. By the time he is done, it has gone from the $1495 I bought from Angie's List to $5200. It's not fair, I called them this afternoon. It is not heating the house like they said it would. We have had to turn the heat up higher. It is making strange noises. I want them to come take it out and give me my money back. My contract says that I have thirty days. Angie's List has a new thing where they guarantee the service. I don't have this type of money and I work hard for my money. I trusted these people and I trusted Angie's List to help me. I don't want to have anything to do with them because, they out right lied. They advertised for the Ream furnace and said nothing about the Trane furnace. They have another check from me for $2050 and they want another $1700 to get the heat to go upstairs. I am still having issues with it. It is noisy and I don't like it. I called them this afternoon and they still have not called me back. She put me on hold and then came back and said that someone would call me back.

"We have called back to honor your wishes but our calls have not been returned. During the installation your husband praised our work for going above and beyond. The "bait and switch" ad being referred to is an ad created by Angies List and we assure you it is not bait and switch. The confusion came when you thought we were to install a mini - split air conditioner that was not on the contract you signed. I assure you for the price you paid we would not even be able to purchase the materials for the gas furnace we installed and the mini-split you thought was included. We have not been paid for the remaining balance of the system at this time and would love to rectify the situation with you. We can assure you that you got a great deal on the Trane furnace in your home right now that we were praised for given our excellent installation. The complaint you have is that the system isn't heating the top story of your building; however, it is your existing ductwork that is not sufficient not the furnace we installed. Feel free to call us back as we have tried calling you to honor your wishes."
