Is Your Air Conditioning System Failing? Here’s What You Need to Know

Reasons your Air Conditioning System Failing

Is Air Conditioning System Failing? When the temperatures rise, the last thing you want to deal with is your air conditioner not blowing cold air. Nothing can ruin a summer getaway like coming home from a hot day and having the cold air from your air conditioner not enough to cool you down. It puts your entire family at risk for heat-related illness and can make for a long night without a good night’s sleep.

Determining why your AC is not running correctly can be tricky, as there is far more than one way for your AC unit to fail. A few of the most common causes of an air conditioner not blowing cold air can include problems within the unit or poor installation. In any case, before you go replacing costly air conditioner parts, it’s important first to diagnose the problem and rule out any more straightforward solutions. In this article, we will discuss the causes of an air conditioner not cooling and a few practical solutions to help you get your home’s cooling back on track.

Is Your Air Conditioning System Failing Heres What You Need to Know

1. Is Your AC Set Up Properly?

An AC system requires precise installation, with the units and components placed according to local building codes. If your AC unit has been installed improperly or some of the components have shifted due to vibrations, your air conditioner will not be able to function correctly.

To rule out installation issues and ensure your system is working, it should look at the connections made and the wires running between components. Ensure all the wiring is connected correctly and secured and nothing has shifted out of place. If your AC unit was professionally installed, there should be a booklet of instructions and diagrams supplied with the unit, as well as a model number. This information can be extremely helpful in troubleshooting any issues with the unit. To ensure a proper job, qualified HVAC installers should be used to install, maintain, and repair your AC unit.

2. Is Your System Maintenance Up to Date?

For your air conditioner to perform at its optimal level, it will need regular maintenance, no different than a car or other complex machinery. Many system parts may need to be replaced or cleaned, and filters must be kept clean for optimal efficiency. Over time, coils and filters can become clogged and create poor airflow, reducing the air-conditioning quality in your home.

We recommend scheduling regular maintenance from Reliable Appliance & HVAC Repair in San Diego to ensure your AC unit is in optimum condition. During these routine maintenance visits, the HVAC technicians can check for any issues and ensure all system parts are properly serviced.

3. Is the Compressor Working Properly?

The compressor is the beating heart of the air conditioner, which is why it must work properly. The compressor helps move the unit’s air to the outside, meaning a damaged compressor can lead to a tankful of warm air being released into the house.

Failure of the compressor could be due to a low refrigerant charge, incorrect voltage, or a failed motor. A stain or residue around the evaporator coils can identify low refrigerant due to a leak. If the high voltage or motor is faulty, contact a professional HVAC technician for an in-depth inspection.

4. Are the Condensing Coils Dirty?

The condensing coils should be kept in good condition, as they are essential for removing humidity from the air. Dirty condensing coils can cause the air to feel damp and stuffy while also reducing the efficiency of your air conditioning system. When the evaporator and condenser coils become dirty and blocked, a condensate pan can become full, creating a block that stops hot air from leaving the system.

If your condensing coils are dirty, you can thoroughly clean them. To do this, turn off the power to your AC unit and let it cool for about an hour or so. Then use a garden hose to spray the outside of the unit, using a plastic brush or soft bristles to scrub away any dirt or build-up from the coils.

5. Is the Fan Not Working?

A fan not operating correctly is one of the most common causes of an air conditioner not blowing cold air. To begin with, check to make sure the fan switch is turned on. If the switch is still not working, fit for any faults or brakes in the fan motor, and also look to see if the blades are correctly attached.

If you cannot identify the cause of the fan problem, contact a qualified HVAC technician to come and take a look. Replacing a fan motor can be expensive, so it’s always best to know the underlying cause before replacing parts.

6. Is the Refrigerant Leaking?

If all of the above steps are unsuccessful, the next thing to look at is the system’s refrigerant. Over time, refrigerant levels can deplete over time, leading to decreased performance in air conditioners. You must find and repair the leak if the refrigerant level is low. Otherwise, you will need to top it up.

To do this, a qualified HVAC technician will inject a dye into the system and then look for any signs of a leak when the voltage is on. You may also need to maintain the pressure to keep the system running effectively.

7. Is the Thermostat Working Correctly?

The thermostat is the other key component of your air conditioner. The air conditioning unit won’t blow cold air if it works incorrectly. This could be due to loose connections, faulty wiring, or a faulty thermostat switch. Be sure to check the thermostat and look to see if the sensors are working.

If everything seems to be working properly, it’s also a good idea to check the fan setting on the thermostat. If this is set to “auto,” the fan will only operate when the AC compressor runs if the fan is set to “on,” then the fan can operate even when the compressor is off.

When the temperatures start to rise, and you find yourself in the unfortunate situation of an air conditioning unit not blowing cold air, the first thing to do is find out why. It could be due to improper installation, lack of maintenance, a faulty compressor, dirty condensing coils, a fan that is not functioning properly, a refrigerant leak, or a thermostat that needs to be adjusted.

No matter the underlying cause is, it is essential to diagnose the issue and address any underlying problems before turning to costly air conditioner parts. Remember that the most effective way to get your AC unit back up and running is to contact a qualified HVAC technician, such as Reliable Appliance & HVAC Repair in San Diego, and have them look at the system.

With their expertise in HVAC systems, they’ll be able to quickly diagnose the problem and get your house back to a cool and comfortable state.

Why Your AC Isn’t Blowing Cold Air and What to Do About It

If you’re wondering why your air conditioner isn’t blowing cold air from the vents, you may want to look into several potential causes. After identifying the issue, you’ll need to bring in a qualified AC technician for professional repair or service. If you’re located in the area, Reliable Appliance & HVAC Repair can help diagnose and repair the main cause of your air conditioner’s problem.

The Causes of Cold Air Not Coming From Your AC

A lack of cold air coming from your central AC system can be caused by a few different issues, each of which requires a different fix:

  • The thermostat isn’t set correctly.
  • The air filter is clogged.
  • The AC unit is too small for the space.
  • The compressor or fan motor is not operating.
  • The refrigerant charge is too low.
  • The condenser or evaporator coils are dirty.

If you’re unsure which of these issues is causing your AC to not blow cold air, Reliable Appliance & HVAC Repair can help you diagnose.

Signs of an AC Breaker Trip

If your air conditioner doesn’t turn on, it could be a sign that the AC breaker has tripped. In rare cases, this could be a sign of a more significant problem, such as a faulty motor or compressor. Before you hire a technician to inspect the unit, check that the breaker is in the “on” position. If it isn’t, you can try resetting the circuit breaker and see if that solves the issue.

Signs You May Need to Replace Your AC Unit

If your AC doesn’t turn on and fails and resetting the circuit breaker doesn’t help, there could be an issue with the AC unit’s compressor or motor. A home AC service technician can determine the problem. If the technician finds that the compressor or motor needs to be replaced, it could be worth investing in a full AC unit replacement. Reliable Appliance & HVAC Repair can help you determine the best way to proceed in cases like these.

If you think any of these signs apply to your AC unit’s problems, your best bet is to call the professionals. If you require help with an AC repair or service job, contacting Reliable Appliance & HVAC Repair is the best way to go.
