Why Is My Air Conditioner Not Cooling the House?
Set your thermostat to AC mode and lower the temperature setting. If the furnace fan kicks in, the problem isn’t in the furnace. If the fan doesn’t run, try resetting the furnace circuit breaker. If the fan still won’t start, call a pro — the fixes shown here won’t work.
What is the AC unit in a home?
Central home air conditioner service systems consist of two major components: a condensing unit that sits outside your house, and the evaporator coil (often referred to as an A-coil) that sits in the plenum of your furnace or air handler. The refrigerant in the A-coil picks up the heat from your home and moves it to the outdoor condensing unit. The condensing unit fan blows outside air through the condensing coil to remove the heat. The condensing unit houses the three parts replaceable by a DIYer: the AC contactor, the start/run capacitor (s) and the condenser fan motor. The condensing unit also houses the compressor, but only a pro can replace that. The A-coil has no parts that can be serviced by a DIYer.
What to do if compressor doesn't start?
If the compressor starts but the fan doesn't, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor. Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts.

How does an AC condenser work?
It converts the refrigerant gasses into liquid form with the help of the compressor. The process cools the refrigerant , releasing all the heat it collected from inside the home. All an AC system parts work together seamlessly to make this complex machine function.
How much does it cost to fix an AC unit?
The average cost for an AC unit repair is about $200 to $600 per fix. Some homeowners spend as little as $100 for basic maintenance or a quick part swap, while others spend as much as $1,000 for more complex jobs and parts.
How does a compressor work?
The compressor pressurizes the refrigerant into a gas, pushing it along the systems cooling loop. The condenser converts it to a liquid. During this process it cools, giving up its stored heat. The evaporator absorbs the heat from inside the house as the liquid “evaporates” into a gas in the evaporator coil.
Why does a condenser coil leak?
Condenser Coil Leak Repair. Leaks within faulty tubes and seals are common reasons for condenser failure. The component’s tubes can rupture, get punctured or become brittle and break apart. The seals can wear and break down after extensive use.
What is coil replacement?

Why does my AC condenser go bad?
The condenser is generally a well-running piece of the HVAC system. However, because of the high voltage required to run it, the moving parts and heat exchange, things will go wrong. Let’s look at the more common failure points of the AC condenser.
Where does refrigerant go in a condenser?
The refrigerant is brought into the condenser through the low-pressure line as a hot liquid. It travels through the coils where the air is passed over to begin cooling it down. The coolant then passes through the coils and to the compressor, which is found inside the condenser unit, below the fan.
What is the purpose of condenser coils?
Condenser coils are responsible for taking the heat out of the compressed refrigerant vapor. As the vapor travels through the coils, the air blowing over them causes a heat transfer that rapidly cools the refrigerant, resulting in the vapor turning into a liquid.
How to tell if AC fan is bad?
Defective AC Condenser Fan Motor. Another sign of a bad condenser is when the motor for the condenser fan doesn’t operate as expected. The Fan motor can seize, run intermittently, or run continuously. If the motor doesn’t run at all, it will cause your condenser and compressor to overheat.
How does a split AC unit work?

What is the most efficient condenser?
The cool water absorbs the heat from the refrigerant during a heat-exchange inside the condenser. The water-cooled condensers are the most efficient, although they also cost the most to install.
What Is a Condenser and What Does It Do
A condenser is in the front of the radiator behind the bumper. Its main function is to help cool and dehumidify the incoming air, making it more comfortable for you and your passengers. The conditioner also reduces your risk of getting sick due to bacteria and mold that grows when in humid environments.

Why is my AC coil leaking?
Low outside temperatures can be one cause. When a filter, vent or ductwork is clogged it can restrict air flow which causes moisture to build up on the coils. Leaking refrigerant is another very common issue and can be easily diagnosed by a technician. Your AC system is a sealed system and should not leak or lose refrigerant so low refrigerant is ...
Why Does Your AC Unit Freeze Up?
When your AC system is freezing up it is generally going to be caused by one of two things. The first is poor airflow and the second is low refrigerant pressure.
Why does my refrigerator freeze?
While airflow blockage from filters, vents and refrigerant leaks are the most common causes of a freezing system there can be other causes. Mechanical failures or faulty seals could be the culprit and will need to be inspected by a trained technician.
Why does my blower fan freeze up?
One other common cause of freeze up comes from the blower fan itself. When one or more of these fans is not working this will reduce airflow and can cause icing. Even a fan with a blade that is dinged or off center can be enough to cause a system to freeze.
Why does my AC system freeze?
When these filters fill up they become clogged and restrict airflow which limits the amount of air passing over the coils. The limited air flow then causes condensation to build up and freeze on the coils and over time will “freeze up” the system.
How does refrigerant flow?
The refrigerant flows through expansion and compression valves in coils. The change in pressure at these coils cools the air around them which then is blown into your home through the ductwork and out to the vents. The unit on the outside of your home is the compressor which compresses the refrigerant.
What happens if a refrigerant leak is present?
Refrigerant Leak. If your system has a refrigerant leak this can also cause pressure to drop and again may lead to ice forming inside the system. When a leak is present the cause needs to be identified and repaired. Once the cause of the leak has been repaired the system will need to be recharged (refrigerant added).
