I am pretty darn blessed! I can sincerely say that in all our adult life I have never had our central heating go out on me; and every single time the central heating, ventilation and A/C machine goes out on myself and others it seems to consistently be in the summer time time months of the year when I am using the air conditioner. It never fails that every single summer time the central heating, ventilation and A/C machine unit goes out right in the middle of a heatwave, however never in the winter when it is very cold. I wonder why this is? I mean our central heating, ventilation and A/C machine is getting just as much use if not more in the winter, so I would think that it would overload from being overworked plus break down at this time. But it has never happened to me! It must be either the brands of central heating, ventilation and A/C units I get or just sheer advantage all together that I never experience a heating plus cooling emergency in the winter time months of the year, but knock on wood this winter does not become the first 1! So far so good, plus winter is nearly over here. Only 1 more month to go before it heats up plus starts transitioning into the summer time time months of the year. But right now it is pretty chilly out there. And our central heating, ventilation and A/C machine unit’s heating system seems to be doing a superb job so far with no concerns whatsoever, plus I actually hope that it will stay this way!
