The Air Filter.
Your a/c unit draws air in through your house, then cools it, where it sends it back out through your vents. When it draws in air, it also sucks in dust and other impurities in the air. You dont want all that junk traveling through your a/c unit, so its recommended that you utilize a clean air filter. Check your air filter and see if its clean. Ideally, you ought to replace your filter once every thirty days or so. If the filter is dirty, your unit is going to work too hard to pull air into the condenser. If this occurs, the unit could freeze up or breakdown entirely. So see to it your filter is clean.
The air thats brought into the unit travels through cooling coils that cool the air. If the coils are dirty, very little air is going to get through, and your house or apartment is going to stay hot. You can clean the coils yourself, or you could employ a professional. Youll need to use an acid mixture to clean the coils, so it can be an unsafe process. Clean coils however, mean cooler air, so make sure those coils stay clean throughout the summer.
Make certain your a/c unit has a lot of Freon. You should only need to charge your a/c unit with More Freon once a year. Any more than that, and you may have a leak. Discovering a leak is tough however, therefore you may need to employ someone to come out and do it for you.
Your a/c unit ought to be examined at the start of summertime so that it can provide you with cool air all summer long. Dont spend money if you dont need to. Try all of these pointers first, then if you absolutely have to, call the A/C man out to see to it your unit is still working. It may be that you require a brand-new a/c unit entirely, but, youll be happy you purchased one when your home continues to be cool as the days get hotter and hotter.
