Your residential air conditioning unit helps to keep you cool and comfortable when it is hot outside. Unfortunately, they are one of those domestic appliances that many homeowners do not pay enough attention to until they stop working properly. As a homeowner, you should always be on the lookout for any signs that may indicate your air conditioner is not operating as it should. Early detection of problems presents an opportunity to find remedies before things can get out of hand. Here is a general breakdown of some typical air conditioning warning signs that should never be ignored.
Air conditioners are designed to operate as quietly as possible. If your AC unit has of late being making louder noise than it usually does, it may be a good move to call in a HVAC technician or an electrician to inspect it. Something might be touching your motor fan or some parts could be loose or disconnected. Unless you call in an expert, you may never know the source of the problem, and this can cost you more money down the road. So keep an ear out for any unusual noises that may come from your appliance.
Conditioned-air not cool
If the air coming out of your air supply vents isn't as cool as it used to be, then this is an obvious sign that something is wrong with your AC equipment. Usually, you will notice that it takes longer for your cooling equipment to attain the desired temperatures, and staying indoors will really feel uncomfortable. The most likely reason for this issue might be that you are running low on refrigerant. If that's the case, you will simply need to get a refrigerant recharge. But before you can recharge your AC unit with new refrigerant, you will need to first check if there are any refrigerant leaks. If present, the leaks will need to be sealed before new refrigerant can be added to your AC unit.
Abnormally high monthly energy expenses
Have you been receiving higher than normal monthly energy bills from your electricity company and you suspect that your AC unit is the reason for your woes? If you failed to perform routine maintenance check on your equipment this year, for example, then your equipment may be having a problem that is causing it to run less efficiently. The best way to save your AC equipment from impending failure is to shut it down and ask a professional to come check it out.
