You can almost guarantee that your air conditioning will need repairing on the hottest day. While this may seem inevitable, your air conditioner may have been exhibiting signs of a problem for days, weeks or even months before it broke down. By being aware of how your air conditioner is operating, you could preempt a breakdown and perform some preventative maintenance by calling in a professional. Even if you are not particularly confident with appliances, there are some major signs which can indicate that a significant problem is brewing.
Hot Spots and Uneven Cooling:
If you walk through your home and notice that some rooms or areas feel hotter than the rest of the house, your air conditioner may be struggling. This is especially a problem when rooms are at the edges of the home, and it can be a sign that the system is losing airflow or has lost some of its cooling power. Hot spots may be a result of the thermostat being incorrectly set, but if you have checked your thermometer it is worth calling a professional for repair advice.
Loud Noises:
Most modern air conditioning units are designed and manufactured to operate as quietly as possible. While it is operating normally, you should expect to hear only a quiet hum and whir as the fans and compressor run. If your AC unit has begun to make loud noises such as hissing, clicking or metal grinding, it is an indication of a problem. Loud noises should not be audible, and if there is an obvious and unusual noise during operation, it is likely to be causing stress on the system and should be looked at immediately.
Utility Bill Spike:
If an air conditioner malfunctions, there is additional stress on the system, which causes it to draw more power than it normally would. Even a basic issue such as a clog in the air vent could produce a noticeable spike in electricity bills. If you have not increased use, but have seen a spike in your utility bills, it is important to investigate the underlying reason. A minor issue compromising efficiency and left unaddressed could cost you a small fortune in increased energy costs.
Reducing the Risk of Repair Issues:
Another way to prevent a major breakdown is to enroll your system in a program of preventative maintenance. Regular servicing and maintenance will involve an inspection and tune up of your air conditioning equipment, which can reduce the risk of a breakdown. Most manufacturers recommend that equipment is serviced at least once a year, ideally in the spring before the hot summer temperatures arrive. The technician will be able to replace components that have become worn before they fail and trigger a more serious repair issue. This regular care can not only reduce the risk of a breakdown, but can also ensure that your system is operating at peak efficiency to reduce energy consumption and alleviate additional strain on the system. This can also contribute to a prolonged lifespan, saving you money now and in the long term.
