Pinpoint the Problem

Concerns about your air conditioner’s performance may arise if the air coming out of it doesn’t feel chilly enough. Fortunately, there are a few straightforward options that could help raise the temperature of the airstream quickly. Restricted airflow and low refrigerant levels are common sources of poor cooling with an AC unit, and in many cases, these can be corrected easily by HVAC professionals.

If the air coming out of your cooling system doesn’t feel chilly enough, you may think that your air conditioning unit has broken down. However, there are a few straightforward options that could help raise the temperature of the airstream quickly and effectively. Poor airflow and low refrigerant levels are two of the most prevalent causes of poor cooling from an AC unit, and in many situations, they may be remedied by HVAC experts.

Facilitating Heat Exchange

Heat exchange, which may seem weird, is what causes the air in your house to cool down. When pressure changes, refrigerant alters temperature. If you put pressure on it it gets hot, and if you let go it gets very cold. The refrigerant is compressed and expanded both inside and outside your home as it travels through pipes and coils.

During the expansion and cooling process, the refrigerant in your indoor coils is absorbing heat from the surrounding air in order to chill your home. The temperature drops, and the air follows suit. In order to maintain a consistent temperature throughout your home, you must ensure that your vents are clean and clear of obstructions.

Low Refrigerant Levels

If your refrigerant charge is too low, an HVAC technician can examine it. Undercharging by as much as 10% might result in a 20% increase in the amount of energy used by an air conditioner. Low refrigerant levels can also indicate the presence of a leak in the system’s pipelines, which would necessitate repair. In some circumstances, refrigerant pipes may be clogged or otherwise malfunctioning. Poor cooling levels will continue to be a concern if the issues are not addressed. Frozen expansion coils and excessive compressor wear are also possible, posing far more serious repair issues.

Changing the refrigerant is not a do-it-yourself project. There are trained professionals who know how to handle it. It’s critical to engage with a professional if you need supplies for your home cooling system, which aren’t readily available to the general public.

Restricted Airflow

Temperatures can be affected by a lack of air flow in your home. Dirty components are the most common cause of failure. If your AC isn’t putting out enough air pressure in each area, a simple look of the air filter can be a good place to start. A blocked air filter is a major contributor to poor airflow, but replacing it is a simple task.

It takes a little more effort to clean dirty coils, and an HVAC professional should be called in. By accumulating on your coils, filth blocks the flow of heat from your refrigerant to the circulating air. In addition to delivering ice-cold air, a thorough cleaning can also provide outstanding air pressure.

Schedule Preventative Maintenance

If you’re worried about dirty coils or low refrigerant, an AC tune-up is a great method to deal with the issue before it gets out of hand. A comprehensive check of your HVAC system by Brennan’s Heating & Air Conditioning professionals will also be performed in order to identify any further problems that need to be addressed. If you want your system to run at its best, we recommend this as an annual service. To schedule an appointment, please contact our Woodbridge, VA office.

Clean Your Air Conditioner Filter

Cleaning your air conditioner filter is an easy technique to make your air conditioner colder if you haven’t done it in a while.

The filter in your air conditioner is very similar to that found in a clothes dryer. If you don’t regularly clean it, it will not only reduce the efficiency of your cooling system, but it will also cause your home to become more dusty and polluted.

Filters on most air conditioners are very similar. Removing and inspecting the wireframe inside your air conditioner’s filter is easy. A fast scrub or a replacement is necessary if it appears dirty, discolored, or otherwise unappealing.

Placement In The Home

Even if you have an air conditioner installed in any area in your home, the room itself has an impact on how effective the unit is. Many people move into a new home with an air conditioner already installed, or simply place one in the living room by default. However, there is a science to getting the most out of your air conditioner, and a lot of it has to do with how your room is laid up.

Of particular concern are rooms that get a lot of direct sunshine. In theory, it seems sense to install your air conditioner in the room with the highest temperature, but in practice, it’s a waste of money. If your air conditioner is located in the hottest part of your house, it will have to work harder and won’t be able to chill the area evenly.

If you’re going to put your air conditioner in a room, make sure it isn’t tucked away behind any furniture, plants, or other obstructions. If you place your unit behind something else, you’ll end up with a less efficient system that will cost you more money in the long run.

Rooms that receive moderate sunlight, are well designed, and feature ceiling fans should be the ideal locations for your air conditioning units for maximum efficiency. The cooler air circulation process will be boosted by the fan’s help if you use a ceiling fan in conjunction with your air conditioner.

Prevent Short Cycling

Your home will be more comfortable and your energy bills will be lower as a result of “short cycling,” a common problem with air conditioners.

Short cycling is the term used to describe an air conditioner’s activity when it cycles on and off often. Your air conditioner will be running frequently, but not for long enough to produce a lasting change.

If your air conditioner is frequently cycling on and off, it could be due to a variety of causes. Environment-related problems are among the most common. Keep a watch on your air conditioner’s outside during bad weather or after major storms since ice buildup, sleet, or harsh winds can all damage it.

Air conditioners are the most prevalent cause of short cycling, especially ones that are too large. People often make the mistake of thinking that “money equals comfort,” therefore they buy the most expensive air conditioning unit that they can locate. This is, in my opinion, a bad idea.

Having an air conditioner that is too large for the room it is cooling could result in it shutting itself off because it has already reached its goal temperature. As a result, the home’s temperature is not maintained consistently, resulting in higher utility expenses. Get your air conditioner evaluated by an HVAC professional to determine if it is built correctly for your house.

Finally, it’s possible that your air conditioner is shutting down prematurely due to a lack of refrigerant in the system. Refrigerant levels and suggested refill intervals should be checked by a specialist from your HVAC company.

Use The Right Air Conditioner Refrigerant

When you add refrigerant to your air conditioner, it does more than merely cool you down.

The copper coils in your air conditioner contain a refrigerant molecule. As a low-pressure gas, your air conditioner’s refrigerant takes in heat from the room and changes state to a high-pressure liquid with the help of the compressor. The refrigerant coils in your air conditioner absorb the hot air and then release the cold air back into the room. The air conditioning cycle goes like this.

In order to avoid this, make sure your air conditioner is properly charged with refrigerant and that the type of refrigerant charged is the correct one.

Refrigerants are available for a wide range of air conditioner models. R-410A (aka Puron), R-407C, and R-134a are the most commonly used refrigerants, each with its own advantages and disadvantages.

There isn’t much of a negative impact on the environment from any of these choices. They claim to have made no contribution to the loss of the ozone layer and are primarily concerned with maximizing energy efficiency.

Start with R-410A as the most common air conditioner refrigerant because it is the most widely used in today’s units. Using R-407C refrigerant in older models may be a good idea. For cars, trucks, and buses, R-134a is the most common refrigerant.

Always double check what refrigerant requirements you think would be best for your home with a trusted advisor. They will be able to better discern the specific needs and best practices for your home’s unique conditions to make your air conditioner colder.

Some people don’t have a lot of money to spend on things like this, so we’ve come up with a few alternatives that might still be beneficial. We guarantee that your air conditioning unit will be colder than ever once you complete this task. Here is a list of steps you can do to get the job done with ease and without any problems. They’re also not too difficult to put together.

This is also for your own benefit, so be careful and cautious at all times to ensure that no one is harmed or inconvenienced. After that, you can finally relax and rejuvenate yourself. As a result, here’s how to cool down an air conditioner:

Method #1. Spraying down your air conditioning unit

When it comes to air conditioning equipment, we can’t help but have dust and other foreign particles collect within. As a result, we’ve discovered a home treatment that, we believe, can be effective with only a few common household items and instruments.

If you notice that your unit isn’t working as well as it should, take a few minutes each week to clean it out. To make sure that your appliance is working properly. Gather the necessary ingredients, a spray bottle, and water-filled inside the bottle to get started.

Make sure that the breaker has been switched off and that all of the sockets are unplugged before proceeding with any more work on the device. Once the appliance has been switched off, you’ll want to spray the condenser unit with a dehumidifier and allow it to dry for a few minutes. So that it can be put to use as soon as the water has evaporated. It’s important that you switch the breaker back on after drying it.

Method #2. Changing your air filters

You’ll have to spend a little money on this one, but it’s worth it because this is the most effective of the previous steps. You won’t have to worry about anything because it’s so simple. You should periodically inspect your equipment to ensure that it does not appear unclean.

If this is the case, it’s time to swap out the filters so the system can function as it did before and save you even more money on energy costs. Because no two appliances use the same filter, it’s best to use this website to narrow down your search and locate the one that works with your machine.

Method #3 Using fans to make the environment colder

These are just a few of the simplest yet most effective techniques to make an air conditioner work harder. At least two or three degrees colder than the air coming out of your AC unit can be achieved by using this device in conjunction with it. The thermostat may be raised without causing any discomfort, thanks to this feature.


As a result, an air conditioner can be made colder. Spraying water on the AC unit, using an additional fan, or changing your air conditioner’s filter will all help you keep your room at a more comfortable temperature. It is common for air conditioners to stop disbursing cold air if they become clogged with dust. Clean the unit on a regular basis. Before you do anything else, make sure your air conditioner is turned off and disconnected from its power source.

Alternately, you might try turning your air conditioner’s temperature down all the way. As a result, I hope you’ve been able to use it in the future at your AC. It’s best to get in touch with your HVAC specialist if all else fails.
