Why Would an Airconditiner Not Cool but After Turning Off and Back on Again It Works

Why is the AC Not Blowing Cold Air?

From very simple problems like a thermostat set incorrectly or a dirty filter...to a more complex situation that requires replacing components...at that place are a wide diversity of reasons why you may find your air conditioner running, but not lowering the temperature in the firm. We'll outline some items yous should check before calling a professional person here. For a little more particular, visit our troubleshoot an air conditioner folio.

Thermostat is Set Incorrectly

When yous notice your dwelling house getting a little hotter than normal, first bank check the thermostat settings. Exist sure it is gear up to absurd. If the thermostat is gear up to cool, bank check the temperature setting to be sure someone hasn't inverse it. If it is off, set up to estrus, or fix for constant fan (sometimes only labeled "on"), switch information technology back to cooling operation. After the organisation kicks on, wait a few minutes, and then cheque for cold air bravado from the registers. If it'south cold, problem solved! If not, move on to the next troubleshooting tip – checking the air filter.

Dirty Air Filter

Your Ac arrangement may include an air filter located in or around the indoor air handler unit of measurement. The filter catches clay, grit and other airborne particles as they enter the air handler unit. Information technology keeps the components within the system cleaner and operating more efficiently and can help keep the air in your home cleaner as well. A muddied air filter can block airflow and reduce cooling to your home. In more extreme cases it can cause the system to close downward completely.

If your thermostat checks out and you withal don't take cool air, locate your system's air filter, turn the arrangement off, remove the filter and audit. If, after you are satisfied that you take a make clean air filter and your central air conditioner does not cool your home, y'all'll take to dig a little deeper to locate the problem.

Condenser Unit of measurement is Blocked

As previously described, your central air conditioning organisation probable includes an outdoor condenser unit. The outside of the condenser unit features a large outdoor ringlet, which wraps most of the way around the outside of the unit of measurement. The curl includes a series of thin metal "fins" which are spaced very tightly together. If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser roll. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your domicile. Dirt, grass and other airborne debris can accumulate between the fins, clogging the curlicue. A dirty coil can lead to reduced energy efficiency, lack of cool air from the registers, or in extreme cases, complete system shutdown or damage to the compressor from overuse. You lot can endeavor to clean the curl by immigration away droppings, carefully vacuuming the coil with a brush attachment or rinsing gently with a hose. If your system even so isn't cooling, it'due south probably fourth dimension to telephone call a pro.

Damaged Rut Pump

In some cases, your outdoor unit might exist a heat pump. A oestrus pump looks just like an AC unit of measurement, with some different components inside that allow it to both cool and heat your dwelling. In cooling performance, information technology operates just like an air conditioner system's condenser unit and is subject field to the same issues – muddy, clogged coil, frozen coil, refrigerant leaks, compressor malfunctions, etc. If your estrus pump system isn't cooling, check thermostat settings, the air filter, and the condenser unit for previously described issues. If everything checks out and you're still sweating inside, call your local HVAC dealer.

Evaporator Coil is Frozen

The indoor component of your fundamental ac organization will include an evaporator coil. If your indoor unit of measurement is a furnace, the evaporator coil sits in its ain cabinet, outside the furnace. If the indoor unit is a fan coil (typically as role of a heat pump system), the evaporator coil sits inside the fan coil cabinet. Warm indoor air passes through the evaporator coil where oestrus energy and humidity are removed from the air. Cooler, more than comfortable air is so circulated back to your dwelling house. Signs of a frozen evaporator coil include:

• Frost forming on the copper refrigerant tubing coming from the coil cabinet
• Inadequate cooling
• College utility bills
• Excessive condensate drainage near your indoor unit
• In extreme cases, frost forming on exterior refrigerant tubing or the outdoor unit of measurement

Because accessing the evaporator ringlet is difficult, resolving problems associated with a frozen evaporator coil are all-time handled past an HVAC professional.

Refrigerant Leak

Refrigerant is a chemical that is disquisitional to the cooling process. Information technology flows through the system'due south indoor and outdoor coil, changing from liquid to gaseous course, drawing estrus energy and humidity from indoor air and releasing it outside. Depending upon its severity, a refrigerant leak tin can contribute to your Air-conditioning organization non blowing cold air, your system may run for longer periods of time without adequately cooling your home, or it tin can cause a damaged or failed compressor and complete organisation shutdown.

Checking and resolving issues involving refrigerant levels in your system is some other chore for your local Carrier dealer.

Undersized Air Conditioner

Air conditioners are "sized" according to the corporeality of cooling they can provide every bit measured in BTUh (British Thermal Units per 60 minutes). Nether moderate conditions, yous may not discover whatsoever issues with an undersized air conditioner. However, as temperatures rise outside, your Ac may run for long periods of fourth dimension and struggle to proceed you lot cool.

Y'all might be able to determine the size of your AC unit from the rating info on the cabinet panel, but it volition be hard to make up one's mind whether it is the "right size" for your home. There are a number of factors involved in sizing a system for your home, including square footage, quality of construction and insulation, local climate, and more.

If your arrangement is undersized, information technology may exist possible to provide cooling in problem areas past adding a ductless unit to assist out in "hot spots". Or, it may be improve to supplant the system with i that is correctly sized. The best fashion to address sizing issues is to contact a qualified HVAC professional who can accurately appraise your home and its optimum cooling capacity.

Contact a Carrier HVAC Dealer

Thermostat non reaching the fix temperature? If yous attain this conclusion and you lot've exhausted the options outlined previously, it's time to telephone call a Carrier HVAC dealer. Information technology'southward of import for your comfort, simply also for the health of your Air-conditioning organization. Continuing to run your AC when information technology's not properly cooling your home can take a minor event and plow it into a major component failure or system replacement.
