Common Problems that Call for Central AC Repair
A malfunctioning AC can quickly turn discomfort into an emergency case on a hot summer day. The situation is even much worse if you have babies, asthma patients, older people or pets in your house. If you have any delicate cases in your house, feel free to reach out for emergency AC repair Santa Clarita.
But what are some of the issues that may result in the need for AC repair?
- Low refrigerant levels– this means that the system possibly has refrigerant leaks.
- Faulty wiring– with faulty wiring, the system cannot draw power, which may result in circuit breaker tripping,
- Outdoor fan not functioning well – if the fan is not working, it results in improper heat transfer. If the repair is not done as needed, it will damage the compressor.
- Frozen coils – often due to a blocked return air duct of dirty and clogged air filters.
Troubleshooting the Central Air Conditioner
Once you notice that your central AC is not functioning well, you need to call an AC repair technician.
However, if you are a rather hands-on person, you may want to troubleshoot and discover the problem. And, you can perform some AC repairs on your own!
Yes, some air conditioner issues need an HVAC technician to solve them. However, some are simple DIYs you can perform on your own.
We troubleshoot some of the issues below.
My AC condenser is not running.
Generally, if your condenser unit won’t turn on, it is most likely dirty. Also, you may have a clogged condenser or fan.
Also, if the unit does not turn on, chances are you have a faulty motor that is not receiving power.
Additionally, make sure that the unit is plugged in.
The first action to take is to clean the AC condenser unit.
Contact HVAC Santa Clarita if the problem persists after cleaning.
One primary reason for uneven cooling is an old HVAC system. If your more than a decade-old AC system is cooling the house unevenly, you need to get an AC replacement. You need to start searching for tips on how to choose central AC unit.
How about if your AC unit is not old?
Here are some of the other issues that may result in uneven cooling:
- Leaky air ducts: Your duct system needs to be airtight. If the ductwork leaks, it will drop the air pressure in it. This results in the cool air going out and becoming hotter. The only way to solve leaky ductworks is to call for a duct seal or replacement from your local HVAC company.
- Short cycling– another reason you have hot and cool spots in your house is short cycling. This is when the air conditioners run for a shorter period than they should. Typically, an air conditioner runs for approximately 10 minutes. If it keeps running for a shorter period, enough cool air will not get to some parts of the house. There are different reasons short-cycling happens. You will need your local HVAC technician to look into it and fix it. If you do not fix short-cycling immediately, it starts happening; it will increase your electricity bills.
- Clogged air filters – if you have not cleaned or replaced your air filters for a long time, they will clog up. Dirty or clogged AC filters will result in a plethora of issues. Clogged air filters block adequate airflow, resulting in uneven cooling. You may want to try and replace the air filters before calling for professional central AC repair.
Is air conditioning not producing enough cold air as before?
Chances are high that your thermostat has an issue. Start by ensuring it is appropriately set. The next suspect will be a dirty or blocked air condenser if all this is okay.
Start by checking the outside unit and the areas around it. Ensure that there is no dirt or debris accumulation. Clear all weeds or vegetation that could be affecting proper air circulation.
If the issue persists after this, contact your local HVAC tech for professional troubleshooting.
My Air conditioner is not cooling the house.
Sometimes, the air conditioning system is on but not working.
Of course, this is a cause of alarm, and you need to call for residential AC repair immediately.
However, if you would like to troubleshoot and try to fix the issue, here is what the issue could be:
- dirty and clogged air filters,
- dirty or clogged condenser coil,
- the blocked evaporator coil,
- air leaks from the duct system,
- Malfunctioning thermostat or thermostat set too high,
- AC unit too small
You can solve some of these issues, such as dirty air filters. If it is beyond this, professional help would be better.
The AC condenser Unit repeatedly turns on and off.
This repeated turning on and off is called short cycling. This means the system is turning off prematurely and turning on shortly after. These short cycles often last 5-10 minutes, depending on the problem’s bad.
It would be best if you solved short cycling because it will increase your electricity bills. You do not want to wait till the bills are over the ceiling.
The leading causes of short cycling include:
- malfunctioning compressor,
- dirty coils,
- dirty filters,
- frozen coils,
- low refrigerant levels,
AC won’t turn on
If your air conditioner doesn’t turn on for some reason, you want to ensure the system is well-plugged in.
If your AC unit is well plugged in, then the problem could be one of the following:
- Tripped circuit breaker,
- blown fuse,
- clogged air filters,
- the dirty evaporator coil,
- dirty condenser lines,
- refrigerant leaks,
- the faulty motor, which is often preceded by weird noise from the AC unit,
- faulty wiring,
- thermostat issues which mean it could be broken, outdated or needs batteries.
Ice on Refrigerant lines or water leaking from AC
Frozen air conditioners are nothing uncommon, even in sweltering summers.
People often discover the frozen line or water leaking from the AC after they notice that the AC is not cooling the house well.
The fastest solution for a frozen line is to turn off the AC system and set the thermostat on fan mode. However, this is only a temporary solution, maybe as you wait for a proper diagnosis from an HVAC technician.
The main reason behind frozen refrigerant lines is the too cold evaporator coil(1). This is typical because the system absorbs less heat, forming ice on the lines.
Other reasons behind ice on refrigerant lines include:
- refrigerant leaks from the evaporator coils,
- clogged AC units,
- malfunctioning blower fan,
- blocked AC vents,
- collapsed air ducts.
Can I Repair my Air Conditioner?
Often, homeowners dial their local HVAC service when an issue develops on their AC, furnace or air handler. It is excellent to allow professionals to deal with any issues with your central air system.
However, the issue at hand could sometimes be easy enough for you to solve. If you are a DIY person, you can save money while at it and understand your AC system better.
Some of the issues you can solve include:
- dirty air filters,
- blocked or dirty outdoor AC unit,

However, some AC problems are better left to the professionals. These include:
- refrigerant leaks,

- malfunctioning motors and blower motor,
- collapsed or leaky air ducts.
Note: If you decide to troubleshoot your central AC system, ensure your indoor air handler and outdoor unit are off. This way, you will be protected from any electrical hazards.
