Hartz Heating & Cooling Inc. has always done great work for me! This was not my first time using them. I use them for properties that I flip and have also had them service my Mom's unit. The unit at my house has not needed service yet but I will absolutely not hesitate to call them! Their workers are prompt and professional. They have good pricing and great products. They are very responsive to phone calls. Mike and Jerry there are friendly and very easy to work with. I think you would be foolish not to use Hartz Heating & Cooling Inc., they really are that good!
