Most people do not think much about their air conditioners until the units fail. Like any other electrical appliances, your AC unit can fail without notice or prior signs. Once your system fails, this is often the time many people realize they haven’t been giving it adequate attention in regard to regular maintenance. But what causes air conditioner failure? Here are some reasons why your AC is not working.
- Clogged Lines
One reason why your AC may stop working is clogged condenser lines. The refrigerant liquid flows through the coils to cool things, but these lines easily get clogged.
If you do not clean the vents regularly, you will block airflow as well. With clogged lines and blocked airflow, you can no longer enjoy your AC unit.
While you can handle the issues by cleaning the vents, you should never try to unclog the condenser lines yourself as they can freeze or cause injuries. Instead, you need to hire a professional. The experts know how to do it safely and will advise you on how to avoid such issues in the future. - Dirty Coils
Dirty coils are another reason why your AC might not be working. Mineral deposits, dust, pollen, and other particles will buildup on the condenser coil over time.
Once the coil is covered, it does not eject enough heat from the unit – this forces the coil to work harder to cool your house.
This increased pressure will overwork your compressor, and it will eventually fail. You can try to remove the dirt by rinsing off your AC with a hose or vacuum safely, but it might not always work. You need to contact an expert who will safely remove rust, dirt, dust, and other mineral deposits. - Refrigerant Leaks
Refrigerant is a critical part of the AC cooler. After some time, the refrigerant lines can break or crack, leaking the refrigerant fluid, and freezing the lines. Eventually, this will shut down your AC unit.
Refrigerant leaks are a common problem with older units. When this happens, you need to replace the lines, and it is not a DIY job. Hire a professional to ensure you get the right lines and the correct refill. - Broken Thermostat
Your AC unit can fail to work due to a faulty thermostat. Like your air conditioning unit, the thermostat also needs proper cleaning to remain functional.
If your AC unit fails, adjust your thermostat to 5 degrees higher or lower, and note if there are any changes. If there are no changes, then your thermostat is faulty. At this point, you need to contact AC professionals for professional installation. - Faulty Wiring
Faulty wiring is another cause of air conditioner failure. Faulty wiring in the circuit breaker, thermostat, air conditioner, or even in your house can lead to AC failure.
Air conditioners require a lot of power. If your home’s wiring system is faulty, you are likely overloading the circuit. Faulty wiring is one of those problems you can hardly diagnose on your own. If you suspect you have faulty wiring, contact your local air conditioning service provider and have them resolve the problem.
