What to Do When Your HVAC Is Functioning But Not Cooling

- in Home Improvement

If you have recently had a heating ventilation and air conditioning system installed, and you are noticing that it is not blowing cold air, this could be an internal problem. In some cases, it might be the thermostat that you are using which is not functioning properly. You can have an HVAC professional come out to examine the thermostat, as well as the entire electrical system. If nothing is found, it might be related to your coolant. More specifically, there might be problems with the entire internal mechanism. There are several components inside of the air conditioning portion of an HVAC unit. If one of them is not functioning, you will not have any cold air. Here is what you should do when you’re heating ventilation and air conditioning system is turning on, but there is no cold air coming out.

Check The Compressor

The compressor is the component of AC unit which is designed to increase the pressure on the refrigerant that you are using. The reason that you want to compress the coolant is that under high pressure, it will make it more effective at absorbing heat. If this is no longer functioning, the coolant will not be able to absorb the heat, therefore eliminating the possibility that you will have cold air come out at all.

Check The Condenser

The condenser is the portion of the air conditioning unit that is a type of heat exchanger. It causes the now gaseous coolant to condense, allowing it to run back through the system. There is typically some type of a fan connected to this device. If the fan is not functioning, or if the condenser is not working, you will again have a lack of cold air. The only way that you will be able to start having cold air again is to eliminate all of the possibilities. Once the HVAC company has checked your electrical system, compressor, condenser, and your thermostat, they may recommend that you change the refrigerant that you are using right now. 

Find Out What Type Of Coolant You Have

The coolant that you are using might be the problem. For decades, Freon was the top choice. However, with it being outlawed, you will need to eventually replace this. You can replace this coolant with many other alternatives. It was the findings of scientists that chlorofluorocarbons were harming the ozone layer that prompted the creation of alternative refrigerants. This is why you will want to change out your coolant, if you do know that you have Freon, as you will inevitably end up with much colder air coming out without using as much electricity.

What Type Of Refrigerants Should You Consider Using?

The refrigerant that you use will be based upon the cost, but more importantly, you need to look at efficiency levels. They are typically made of a mixture of different chemicals which are known to have heat absorbing capabilities. One type of coolant called TDX 20 is fast becoming one of the more popular replacements for R-22. It will require you to work with an HVAC professional that will have the knowledge and expertise for removing the Freon and replacing it with something else. Other alternatives will include R-407C and R-134A. These are not only very efficient, but they are not chlorofluorocarbons, and therefore any leakage will not be a detriment to the ozone layer.

Will It Take Long For The HVAC Company To Exchange The Coolants?

The amount of time it will take to switch out these coolants will be minimal. This is because the HVAC business that you hire will have the best tools and the knowledge to get this done. They have probably performed this task hundreds of times. It is becoming more prominent as we move closer to the 2020 deadline of eliminating Freon from refrigeration units. If the company you have hired to troubleshoot your HVAC system tells you it must be the coolant, you then need to make a choice. Of all of them, TDX 20 is one of the better choices because of how it can help reduce not only the probability of harming the ozone layer, but it will also help with diminishing the greenhouse effect.

How You Will Recoup Your Initial Investment

Recovering the money that you will spend on these refrigerants is a virtual guarantee. Within a few years, perhaps sooner, your electric bill for running your HVAC system will be far less than ever before. If you are not changing any of the components, and you only change the refrigerant, you will see that this is one of the better decisions you can make. Your electric bill should diminish, sometimes significantly, and you won’t have to worry about leakage. Every one of the new replacements for Freon is designed to not affect the ozone layer, and these refrigerants can also be beneficial in preventing CO2 emissions because they will not overwork the different components of your AC unit.

How To Find The Best HVAC Company To Help You

Heating ventilation and air conditioning companies can be found quickly online. It is recommended that you work with one that has extracted Freon from refrigeration units in the past. The company that you choose may have a reputation for not only being affordable, but extremely competent at removing and replacing your old coolant. Once this is done, your electric bill should go down, and your efficiency should go up, regardless of the type of machinery that you are using that will need a refrigerant.

The best way to troubleshoot an HVAC system that is not blowing cold air is to call someone to do it for you. You might have a general idea of how AC units work now, but that doesn’t mean that you will know how to fix them. It is always recommended that you start first with the thermostat, and then over time, try to figure out what is wrong with the internal mechanism. This research, and ultimately the restoration of your AC unit, should be accomplished with a local professional.
