My aunt and our many cousins moved into a new condo about a year ago. Well, it was new to them; the condo itself is actually pretty old. And of course, what comes along with an older condo is an older heating system and an seasoned central air system. The inefficiency of the heating system and the a/c has been the least of their worries, though. And even the heating and a/c bills, though extra high, have not been the largest issue that our aunt and cousins have had, and no, the worst part about this condo has been the fact that our aunt and our cousins have been sick since they moved in! No 1 could figure out what the complication actually was, however all many of them had headaches almost non-stop. They would also experience unexplained nausea and dizziness on a correct basis. Well, our aunt started thinking that maybe his condo was haunted or something! She was absolutely starting to panic. I suggested that maybe before he called in a priest or a couple of ghost-hunters, he should call 1 of our local Heating as well as Air Conditioning companies and make an appointment for them to come and check out the state of the house’s old heating system and a/c, he took our advice and when the Heating as well as Air Conditioning techs came out and evaluated the heating system, they found that there was a large leak in the heating system, but carbon monoxide was actually leaking out into their condo on a correct basis and they had no idea it was what was causing all of their headaches! Thank goodness they listened to our advice and had the Heating as well as Air Conditioning workers out to test the heating system.
