Our coolant caused a lot of concerns in our central cooling system last summer, the people I was with and I had only had our central cooling system for a few weeks when it first presented some concerns; I called our brother who is an Heating & Air Conditioning serviceman & asked him if he could come see what was wrong with our current central cooling system, but my brother told myself and others that the cooling system was out of coolant & it would need some before I could use it again. I went to the heating & cooling business, not entirely sure what I was doing, & bought the first bottle of coolant that I could find, along with a current air filter, just in case our central cooling system needed a current a single, when I arrived apartment I poured all of the coolant into the central cooling system, then went to our smart temperature control to turn it on! After about twenty minutes of running, our cooling system started to release a peculiar smell through the air vents of our home. I was a bit worried & I went to our smart temperature control to see if anything was wrong & the smart temperature control said that there was a concern with the coolant I put in. I was exasperated at this point because I didn’t want to have to go back to the heating & cooling business to get even more coolant, & I also wasn’t sure what the central cooling system would need more coolant when I had just filled it. Well it turned out that My brother, the HVC serviceman, had to come over & look at our central cooling system, he discovered that I bought the wrong coolant.
