Asking an air conditioning company to send a technician to your house or business can feel like a big step to take. Not paying for air conditioning repair services in a timely fashion, though, may prove to be penny wise and pound foolish. Before you shell out money for air conditioning services, you'll probably still want to know that the expenditure is worthwhile. Here are 5 ways you can tell it's time to contact an AC repair technician.
Although this problem may be as simple as a blower no longer working, the job calls for an understanding of the electrical systems in the AC unit. You can try a few no-brainer tricks, such as checking that the vents are completely open and that nothing is in the way of the airflow. Once you've done those, it's time to contact a pro.
Your air conditioning system should never blow warm air. If there is heat coming out instead of cold air, you're likely looking at a problem with the condenser, compressor, or refrigerant. These are all issues that a pro should handle, and anything involving the refrigerant is probably illegal for anyone unlicensed to address.
There are spinning parts in your AC unit, but any noises that are out of the ordinary are probably signs of trouble. If the noises sound loud and metallic, don't press the issue. Shut the system down right away. Even if the noise is slight, you should contact an air conditioning company if it doesn't go away within a few minutes or if it comes back repeatedly.
Notably, an AC system might emit a few odd smells the first few times you run it after it hasn't been on for a long time. These smells should disappear within a few days of regular use, though. You can check the outdoor components for potential problems like decaying leaves resting on vents. It's also worth giving the indoor vents a good dusting. After you're tried those and given the system a couple of days, any smells you detect from there forward ought to be investigated by a technician.
Higher Electric Bills
Sometimes a system can compensate with declining efficiency for a while by drawing more power. This will largely keep output up, but it could run your bills through the roof. If there isn't a simple reason why the bills went up, such as a hot or humid summer, you'll want to have the unit checked out.
