Why Is My Air Conditioner Not Cooling?

Have you noticed that your home’s air conditioning system doesn’t feel as if it is cooling properly, or maybe even blowing warm air? This is one of the most commonly asked questions among Orange County residents when they are having home cooling issues.

If you’re wondering what could be the cause of this annoying disturbance in your home comfort, then we can help. Read on to learn the causes and solutions to this fairly common problem. We’ll help you troubleshoot this annoying problem.

First, decide what type of problem you’re actually experiencing with your A/C:

Air Is Blowing Out of the Vents, But It Is Warm Air

This is a very common issue that people notice. Here are some great steps to follow if your A/C is functioning, but the air is not coming out cold.

Examine Your Air Filter

Have you been checking and changing or cleaning your air filter regularly? If not, then you could have a very dirty air filter. A dirty filter can block the airflow to your system’s air handler, causing the air that is coming out of your home’s vents to blow out warmer and weaker. If it’s been a long time since you’ve changed your air filter, then do so immediately and see if that alleviates your issue. If it’s been a really long time since you’ve changed your filter, change it. Then, call in an HVAC tech to check out your system for any potential damage not changing the filter could have caused.

Check Your Thermostat

This may seem silly to have to mention, but occasionally the cause of your A/C blowing warm air is that sometimes the fan is set to “auto” or “fan”, which causes your system to continuously circulate air throughout your home, even if the cooling unit isn’t running. This can happen for a variety of reasons, oftentimes it is just accidentally switched on. Check this out to make sure it’s not just an incorrect setting on your thermostat causing warm air to come out of your vents.

Examine Your Outdoor Unit

If you’ve been paying decent attention to your home’s indoor A/C unit, but don’t really pay much mind to your outdoor unit, then do so now. If the unit is covered in weeds, leaves, grass or other debris, it can inhibit how effectively it will cool your home. Clear any debris from your outdoor unit and keep it free from outdoor buildup.

It Could Be a Refrigerant Leak

If none of the above solutions fix your A/C, then it could be a refrigerant leak. Unlike gas in your car, your A/C doesn’t “use up” refrigerant. So, if your air conditioner is low on refrigerant liquid, that means that there is a leak in your unit, and you will need to call in a professional HVAC technician to fix this problem.

If Your A/C Isn’t Blowing ANY Air

If your air conditioner simply isn’t blowing any air at all, then it’s a good time to call in a professional to help assess the problem. It could be electrical or a failure in the system itself. Oftentimes an A/C will shut down to prevent bigger problems, such as overheating or water damage to your home.

The Importance of A/C Repair & Maintenance

The Importance of Proper A/C Care

Numerous problems can crop up with any large appliance, and an air conditioning system certainly is no exception. When faced with Southern California heat, you will absolutely want your air conditioning system to be working properly, so you don’t have to be chasing down an A/C repairman while you struggle through the sweltering temperatures at home.

Although it is likely that you will need to fix some issues that occur with your air conditioner on your own, such as changing a dirty air filter, there are many reasons why you would want to hire an air conditioning repair expert. Since A/C systems are quite complex, it is best not to have to do major repairs (which require opening the appliance) on your own for safety reasons as well as the protection of your air conditioner. When an air conditioner malfunctions, it will probably begin to lose its ability to properly cool your home. This also results in a higher energy bills and a good deal of discomfort, particularly for those of us residing in Southern California. Read on to find out why air conditioning maintenance and repair is important.

Why You Should Only Hired a Quality Professional Technician

It is advisable to find a trained and qualified air conditioning contractor to undertake your A/C repair work. Trying to repair a system on your own may lead to further complications, resulting in higher costs to cover even more repairs from the damage caused. If you have a good understanding of problems your A/C might develop, it is easier to determine the kind of repairs or services the unit requires.

If you live in Orange County and want to ensure that you stay cool this summer, then it’s a good idea to locate a reliable company that can undertake air conditioning repair, such as McMaster. Seek out a company that has an excellent reputation and is also licensed to operate in California.  

Air conditioning systems are generally very reliable and are built to last for quite a long time. However, they will still require regular maintenance and occasional repairs.

Understand the Scope of Your Problem

Before calling a technician for your A/C repair, you can try to determine what the problem with the unit is, so that you have an idea upfront what types of repairs you may be facing.

  • An A/C unit that’s too noisy probably most likely a problem with the maintenance belts or the ductwork of the home especially if it is not sealed correctly. Knowing where the noise is coming from can help determine the problem.  
  • When you notice water forming all over the air conditioning unit, the issue might be with the drainage system of the unit. Either the condenser’s drain lines could be obstructed or the drain pipe might not be functioning properly. You should be able to easily unblock the line on your own, but if this does not work call in a professional to help.
  • Sometimes the air conditioning might not produce sufficient cool air. This generally means that the refrigerant must be filled, which can only be done by a professional.
