“

I called Reliance yesterday to check my home furnace and next day morning their technician Mr.Mick (Australian guy) came and did the required job done with my full satisfaction, he was very polite, courteous and knowledgeable person. Thanks Reliance for having fully trained technicians and I strongly recommend Reliance Home Comforts to All.
