I was pretty surprised to find out that the local heating and air conditioning company in the area that I just moved to only takes mastercard! I luckily have a mastercard so there is no problem, but not everyone does. I wonder why that is the only credit card that the heating and air conditioning company takes. I have never heard of a heating and air conditioning company to only take one card! I really like this heating and air conditioning company so I am not going to say anything to them about it. But it is something that really boggles the mind. I am sure that this limits their business all together by only taking one type of credit card. I can say though that the heating and air conditioning company is one of the best I have ever had though. When I have a heating and cooling emergency they are there. Even if I have to pay for emergency heating and air conditioning home services they will make it a point to take care of things and fix my central heating and air conditioning system in the middle of extreme weather, and I always make sure to have my mastercard ready to pay them since it is the only credit card they take. I hope that I never have to change card companies, because if I do I will have to go hunting for a new heating and air conditioning company to provide me with the heat and a/c home services I need because I never pay in cash.
