Refrigerant Leak Issues to Fix Now
If your air conditioner is leaking refrigerant, there can be a number of symptoms to clue you in. From a hissing or bubbling noise, to lowered system efficiency, to even lukewarm temperatures coming from the air vents in your home, refrigerant leaks make it harder for your system to work.
If you notice any of those listed symptoms, or you suspect there’s something troubling your air conditioner, then call our team. It could be from a refrigerant leak.
How to Deal With a Clogged AC Air Filter
Contrary to popular belief, your air conditioner’s air filter is not designed to improve the air quality of your home. While it might do that as an added bonus, it’s actually meant to protect the sensitive interior components of your AC from encountering contaminants like dust and debris. The more clogged your air filter gets, the more likely you are to run into problems like poor efficiency and an overheating air conditioner.
Solving Foul Odors From Your AC
Did you know that your air conditioner can actually be the culprit of what we call a “dirty sock smell?” If you’re getting some foul odor that smells like mold or mildew coming from your air vents while the air conditioner is running, there could be two problems occurring.
For starters, you could have mold growing in your air ducts. And you could also have mold growing in the condensate drain of your air conditioner. Either problem needs to be fixed by a professional before you get sick or uncomfortable.
Strange AC Noises and What They Mean
Noises can be a great way to detect when your air conditioner is suffering from a problem. Your AC should only make two noticeable noises, the first is a single click when the system turns on or shuts off. The second is the gentle whirring of the unit running while it sends cool air through the air vents of your home. If you detect any other noise coming from your system, then we urge you to call us!
How to Fix Short Cycling in Your AC
Short cycling is an industry term we use to describe a system that’s running in short, frequent cycles. This is bad because it’s energy-intensive and it also causes a lot of wear and tear on specific components of the system. If you’re noticing these frequent cycles, there’s probably a problem under the hood and it needs to be addressed.
Frequently Asked Questions
Question: What are common signs of a refrigerant leak in my air conditioner?
Answer: A refrigerant leak often shows up as hissing or bubbling noises from the system, reduced cooling performance, and lukewarm air blowing from the vents. Low refrigerant makes it harder for the system to cool efficiently, so calling an HVAC professional is important to locate and repair the leak.
Question: Why is a clogged air filter bad for my AC and how can I tell?
Answer: A clogged air filter restricts airflow, causing poor cooling, reduced efficiency, and potential overheating. You might notice weak airflow, longer run times, or short cycling. Replacing the filter regularly can help prevent these issues and keep your system running smoothly.
Question: What does strange noise from my air conditioner indicate?
Answer: AC units should run quietly with just a click when starting and a gentle hum while operating. Unusual sounds like grinding, squealing, or banging often mean something is wrong, such as loose parts, motor issues, or wear and tear, and you should have a technician check it.
Question: What causes foul odors from my AC vents?
Answer: Foul smells can be from mold or mildew growth in the ducts or condensate drain, or even dirty filters trapping pollutants. Musty, mildew-like odors usually indicate moisture problems and need professional cleaning to ensure healthy indoor air quality.
Question: What does “short cycling” mean and why is it a problem?
Answer: Short cycling is when your AC turns on and off frequently without completing full cooling cycles. It can be caused by issues like a dirty filter, low refrigerant, or thermostat trouble, and leads to increased energy bills and wear on the system’s components, so you should have it inspected by a pro.
