I have a 100 year old house with a radiator heating system. I did some research and found Day & Night Mechanical Solutions Inc. were able to install an air conditioning mini split unit which does not require forced central air and is a ductless system. I love that they knew about the split air conditioning and the mini split ductless air conditioning system. They were able to present to me the way that they could set this system up. They communicated very well with me during this whole project, they finished installing when they said they would. Sharmain was terrific in her communication with me and I would be "proud" to be used as a reference for this type of air conditioner mini split ductless air conditioning system. I am very pleased with every aspect of this job!
