Q: I've but turned on the air conditioner for the summertime, but I just tin't get become comfy. The appliance circulates air, just it is not blowing cold air. Why is my air conditioner not cooling? More important, how tin can I set it?
A: It'due south the last matter you lot want on a sweltering summertime's solar day—a central air conditioner not blowing cold air. While your first reaction may be to contact an HVAC pro, with a footling of your own troubleshooting, you might remedy the problem and salve on a costly house call.
Air conditioning systems operate on a basic scientific process called "phase conversion."
- Refrigerant, the liquid used in an AC system, undergoes a continuous cycle of evaporation and condensation within the unit of measurement'southward sealed curlicue system.
- The unit's evaporative coils (commonly located inside your home near a blower unit) get icy cold as the refrigerant inside turns from a liquid to a gas.
- The unit'due south fan blows air over those icy coils, which forces cooled air through your abode's ducting.
- The gas then cycles back to a condenser curl unit (located outside) where it cools back down to a liquid and the cycle repeats itself over and over.
If your AC system is blowing warm air, several culprits may be to blame. The post-obit are a few things to check when your air conditioner is not cooling your space.
Check and reset the thermostat.
It may seem uncomplicated, but sometimes when an air conditioner is working but not cooling information technology is but the result of someone switching the thermostat from "Automatic" to "Fan."
When the switch is set to "Automatic," the thermostat switches on the air conditioning when the indoor temperature rises above the desired preset temperature. If the switch was accidentally set up to "Fan," the unit of measurement volition blow air through the duct system, but no cooling will have identify.
Like shooting fish in a barrel DIY Prepare: Check and reset the switch from "Fan" to "Automatic."
Replace the dingy filter.
If it's been more than than a couple of months since you've replaced the return-air filters in your AC system, they may exist clogged, dirty, and affecting air flow. When filters become clogged with animal fur and dust, the AC system can't depict in sufficient air, and as a event, simply a wimpy catamenia of air comes out.
Like shooting fish in a barrel DIY Fix: Remove the return-air filter and, if you can't meet what's on the other side, replace it. If you can run into through the filter, your problem with your Air conditioning non cooling lies elsewhere.

Articulate the clogged condensation drain.
Air conditioners work in part by removing humidity from the air (through condensation), and that wet must get somewhere. The job of a condensation drain hose is to direct water to a floor drain or to the outside of your dwelling, depending on your system. Condensation drains are subject area to blockage by mold and algae growth. When this happens, some AC won't blow cold air while others will shut downward completely.
Like shooting fish in a barrel DIY Gear up: Locate the end of the condensation drain line (it'south often in a utility room) and visually inspect it for clogs. If yous see a clog, carefully articulate it out with the end of a small screwdriver or like narrow item.
If a clog forms higher in the line where you can't physically reach it, suctioning on the cease of the line volition commonly remove it. Use the hose on a wet/dry shop-type vacuum—and agree your hands around the opening—to create sufficient suction between the two hoses.
Later on removing a mold or algae clog, pour a couple of cups of white vinegar into the condensation pan that lies below the evaporator coils in the inside blower unit of measurement (learn how to access and place the coils and the condensation pan below). The vinegar will kill remainder mold buildup and reduce the run a risk of future clogs.
Endeavor to diagnose duct malfunctions.
In a cardinal AC system, the main blower forces cold air through the ducting and into individual rooms. If a duct somewhere between the blower and a room register (the grill that covers the opening of an HVAC duct) has broken, the cold air could be bravado out before information technology reaches the room's register. If cool air is bravado from some registers but not from others, there'due south a practiced hazard the ducting that feeds the registers is at fault.
Easy DIY Fix: If you have an unfinished basement, you can examine the ductwork to see if a joint has come loose. If so, refit the ends of the joint and tape the new joint deeply with duct record. If a ducting joint has come loose within a finished wall, nevertheless, you lot won't be able to easily locate it and will need to call an HVAC professional.
Articulate the area around the compressor.
If dry out leaves and debris have piled upwardly adjacent to the compressor unit of measurement, information technology may not be able to draw in sufficient air. To find out, locate the compressor unit, which volition typically be tucked away on the dorsum or the side of the house where it won't draw attention.
Easy DIY Fix: Clean away all debris or annihilation else that might be crowding the unit of measurement, such as weeds or overgrown vines. For peak functioning, don't place annihilation on tiptop of the compressor.
Make clean dingy coils.
If your air conditioner is working simply not cooling, dirty coils may be the culprit. The typical Ac system has 2 sets of coils: condenser coils, which are located in the outside compressor unit and evaporator coils, which are encased near the indoor blower unit of measurement. When either set of coils becomes dirty or covered with mold and debris, cold air output can suffer. Cleaning the coils involves removing the metal enclosures that protect them.

Easy DIY Fix: If you don't feel comfy opening the AC units you can ask a pro to clean them. If you'd like to endeavor cleaning the coils on your own, however, follow these steps:
- Shut off the ability to both the exterior and interior units at the breaker panel. Each one will be on a separate billow.
- Follow the AC manufacturer'due south directions for removing the exterior compressor muzzle or the metal panels that business firm the evaporator coils.
- To make clean interior (evaporator) coils, spray a non-rinse evaporator coil cleaner such equally Nu-Calgon Evap Foam No Rinse onto the coils, which resemble U-shaped copper or steel tubes. The non-rinse cleaner foams upward on the coils and dissolves dirt and grime before liquefying and running into a condensation pan that empties into the condensation drain hose.
- To clean exterior (condenser) coils, spray the coils, and the thin metal fins that surround them, with a condenser coil cleaner such equally Nu Calgon'southward Nu Smash Condenser Coil Cleaner. This cleaner is unlike from evaporator gyre cleaner and it volition require rinsing with the hose. Follow the product directions carefully.
Know when it's time to call a HVAC pro.
If you've gone through the to a higher place DIY steps and your Air conditioning organisation is still non cooling, the problem could be leaking refrigerant (Freon) or a failed compressor unit. Freon is federally regulated and may only exist handled by a licensed HVAC professional. If the AC non blowing common cold air is the issue and your Air conditioning organisation is more 10 years quondam, you may take a failed compressor and demand to buy a new arrangement. These issues tin only be addressed by the pros, so make the call!
Final Thoughts
When an AC unit is non bravado cold air, there are many possible causes that can exist hands fixed without the help of a professional person. From changing the filter to checking the settings to cleaning the coils, information technology's possible to get your air conditioner working once more quickly and go along your dwelling house cool. However, if you've tried all of the air conditioner troubleshooting and DIY fixes, and information technology'south still not working, it's time to call an HVAC professional for an evaluation.
