If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. A leak not only keeps the AC unit from cooling properly, but also it can cause other issues within the home.
Why is my air conditioner running but not cooling the house?
If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.

Why is my air conditioner not cooling my house below 80 degrees?
Change the Filter If your filter is loaded with dust and dirt, it could be causing your air conditioner to not run effectively. If you haven't changed your filter lately, now might be the time to do so. Filters keep dust and other contaminants from building up in your air conditioner.
Why is my house so hot even with AC on?
Air leaks and poor insulation are a common cause for making your house feel hot, even when the AC is working, as they can allow the air your air conditioner has worked so hard to cool to escape, leaving your house hot. Humidity can interfere with your thermostat's ability to track temperatures and also traps heat.

These sounds are definitely a sign to schedule your air conditioner maintenance. Puddles or moisture around any part of your HVAC system could mean there's a refrigerant leak.
Is it OK to spray water on your air conditioner while it's running?
Yes, for sure you can. Spraying or splashing water on the condenser unit of an AC won't hurt it, it will increase the cooling efficiency momentarily, and it will help flush out any dust or dirt that might have accumulated due to the airflow through the unit.
What would the symptoms of a dirty coil be?
An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC's operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.
How cool should my house be if it's 100 outside?
Why does my house feel hotter than the thermostat setting?
Poor air flow, bad sensors, or other broken components can also cause room temperatures to be different than your thermostat setting. The biggest clue that your furnace is the culprit is your heating bill.

How do I reset my thermostat?
Reset the Thermostat Common methods for resetting a thermostat include installing the battery backward for five seconds, pushing a recessed reset button with a pin or paper clip, or shutting off the breaker to the thermostat for 30 seconds.
How long does it take for an AC unit to reset?
Your air conditioner's internal circuitry needs some time to reset after you turn it back on. This can take approximately a half hour, so sit tight for about 30 minutes. Turn your air conditioner back on at the thermostat. After 30 minutes has passed, turn your air conditioner back on at the thermostat.
Where is the reset button on my compressor?
A reset button can be found inside the air conditioner's compressor. Typically, the button is red in colour and modest in size.
What does it cost to replace AC compressor?
How long does an AC compressor last?
Your air conditioner compressor should last the whole lifespan of your air conditioner, about twelve years or more if you choose a ClimateCare air conditioner. However, it might not last that long if your air conditioner is too small for the space it's cooling, or if you don't keep your air conditioner well-maintained.
How often should you clean your outside AC unit?
How Often Should You Clean the Outside Unit of AC System? For most homeowners twice yearly is sufficient, once before the summer season sets in and you'll be cooling your home, and once during fall before cold temperatures set in and it's time to switch to heat mode.
Is it necessary to clean AC outdoor unit?
Outdoor units take a lot of dust, dirt and different debris, so that is why it is always a better idea to start cleaning from the outside. Duct cleaning is also important because it increases the efficiency of the air conditioner.
Can you clean AC coils yourself?
While there are a number of commercially available coil cleaning solutions on the market, air conditioner coils can be cleaned with a solution of a mild household detergent and water. The detergent and water mix is applied to the coil using a low-pressure sprayer.
How often should AC coils be cleaned?
In most cases, you can get away with cleaning your coils once a year with a seasonal tune-up. However, you should consider where your unit is located. If you're in a big city with heavy air pollution, you may want to have the coils cleaned two times a year.
How much does it cost to clean AC coils?
A technician can clean the condenser coil in about 1 hour, which typically costs about $150.
What happens if you don't clean AC coils?
The short answer. Dirt & grime on AC coils makes it harder for your equipment to transfer heat. That means it has to run longer and work harder to do it's job, using more energy and causing parts to wear and break down. Dirty coils also get corroded which leads to refrigerant leaks.
What happens if you don't clean your air conditioner?
Dirty filters restrict the flow of cold air which can cause it to build up inside the air conditioner. The final result could be the formation of ice on the coils.
Why is my air conditioner blowing out air but not cooling?
When the switch is set to “Automatic,” the thermostat, which is an integral part of the system, switches on the air conditioning when the indoor temperature rises above the desired temperature that you’ve pre-set. If the switch was accidentally set to “Fan,” however, the unit will blow air through the duct system, but no cooling will take place.
What happens when your air conditioner compressor goes bad?
If the compressor is broken or going bad, you will notice many changes in your AC performance. Most notably, you won’t have cold air inside.
Why is there ice build-up on my air conditioner?
Ice build-up is a condition that occurs when the evaporator coils become too cold. This often results in the moisture in the vicinity of the coils condensing onto the coil and freezing. Signs of ice build-up include a suspiciously hot compressor. The compressor may even ice up or burn out. Different issues can cause ice build-up.
Why does my AC coil freeze up?
A dirty filter can also decrease airflow across the coil, resulting in freezing. Faulty metering devices and an oversize AC system can also cause evaporator coil freezing. Solution: If you suspect ice-build-up, the first step is to turn off the air conditioner and let the ice melt away.
