Having the proper refrigerant level of an air conditioning system is one of the key components to having properly cooled indoor air. The AC specialists at Carney Plumbing, Heating & Cooling can easily diagnosis the AC problems which could be a result of low refrigerant levels get your system back up and running in no time.
How Low Refrigerant Levels Cause AC Problems
One of the most common signs of low refrigerant levels is having an air conditioner that only blows warm air or one that does not sufficiently cool an entire indoor space, leaving some rooms which are warmer than others. This is because refrigerant is what creates the cold air, and without enough of it, you can never have enough cold air.
Frost build-up or icing around the condenser coils in the outdoor unit can mean a refrigerant leak has caused low refrigerant levels. Because ice build-up in your AC restricts air-flow, this can mean less cool air flowing into various rooms. Low levels of refrigerant can cause coils to drop in temperature which then creates frost or ice on the coils.
An AC system that will not turn on could also be a result of low refrigerant levels. Newer HVAC systems have built-in safety controls which detect certain changes in how internal systems function and as a safety precaution, shuts down the air conditioner in certain circumstances rather than continuing to run and further damaging other internal mechanical or electrical systems, especially if your air conditioner makes unusual noises.
These are some of the main AC problems caused by low refrigerant levels. It is important to have a professional Harleysville air conditioning company such as Carney Plumbing, Heating & Cooling assist you with your air conditioning concerns. Our AC technicians provide air conditioning services such as air conditioner maintenance and repair, including fixing refrigerant levels and charging refrigerant.
Frequently Asked Questions
Question: What problems can low refrigerant cause in an air conditioner?
Answer: Low refrigerant can make your air conditioner struggle to cool your home properly. It may also cause the system to run longer than normal, reduce efficiency, and put extra stress on key components. If ignored, refrigerant problems can lead to bigger AC repairs and possible compressor damage.
Question: How can I tell if my AC is low on refrigerant?
Answer: Common signs of low refrigerant include warm air from the vents, weak cooling, longer run times, ice on the coil or refrigerant line, and unusual hissing sounds. These symptoms can overlap with other AC problems, so a professional inspection is the best way to confirm the cause.
Question: Why does low refrigerant make an AC freeze up?
Answer: Low refrigerant can disrupt the normal heat absorption process inside the air conditioning system. When the evaporator coil gets too cold, moisture in the air can freeze on the coil. Once ice builds up, airflow and cooling performance can drop even more, making the problem worse.
Question: Can I just add more refrigerant to my air conditioner?
Answer: Refrigerant is not something an air conditioner should use up during normal operation. If the level is low, there may be a leak that needs to be found and repaired. Simply adding more refrigerant without fixing the underlying issue can allow the same problem to return.
Question: Should I call a professional for low AC refrigerant?
Answer: Yes, low refrigerant should be handled by a trained HVAC professional. Refrigerant requires proper tools, safe handling, and accurate diagnosis. A technician can check the system, look for leaks, recharge it correctly if needed, and help prevent further damage to your air conditioner.

A good air conditioner is a life saver in the midst of a hot and sticky summer, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your Newtown air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.
- Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems.
- Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
- Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to have a tech clean the condensate line and check for any clogs or blockages in the system.
- Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a Newtown AC professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
- Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.
Most noises from your Newtown central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call Carney Plumbing, Heating & Cooling before the problem grows.
