Do you have a home with a cooling system that doesn't seem to work properly? Is the interior temperature rising, despite having the thermostat temperature turned down? As with any other system, it's possible for your air conditioner to stop working for reasons that aren't initially obvious. Sometimes, you can do something to fix the issue and sometimes you'll have to call a professional for help in order to have a working cooling system once again. Some things that you should check that may or may not be obvious include:
Change thermostat battery: Modern thermostats often have batteries even if they are hard-wired into the air conditioning system. If your thermostat has an LCD panel and is programmable in any way, it likely has a few batteries installed to keep the settings in place in the event of a power outage. Since these batteries are generally unused, they can last a long time and may become forgotten. When the batteries become bad, however, your thermostat may attempt to warn you of this fact in a variety of ways. One of the things it may do to get your attention is by being unwilling or unable to communicate with the air conditioner unit itself. If you can't recall the last time the batteries were changed, put in fresh batteries and see if that solves some or all of the issue.
Replace the filter: When you buy a filter for your air conditioning system, the filter manufacturer will tell you how long the filter is supposed to last. This can range from 30 days to several months. But one thing to remember is that these times are not guarantees. Having a lot of dust, pollen, or pet hair in your home can cause the filter to clog prematurely. A clogged filter will make it more difficult for your air conditioner to draw air and it may shut down to protect itself from potential burn-out. If the filter looks dirty, it probably needs to be replaced.
Clean the A/C unit: If your air conditioner is on the ground instead of being a roof-mounted one, you need to make sure that the unit itself and the surrounding area are kept free of debris. A lack of airflow can severely impact how well your air conditioning unit functions. If it hasn't rained in a while, hosing down the unit may be helpful. If you suspect that the interior of the unit needs to be cleaned out, don't attempt to do this yourself. Instead, call a service professional who will know how to clean leaves, spiders, and other unwanted items out of your air conditioner without damaging the air conditioner itself.
