When a homeowner with a malfunctioning air conditioner wants to know what’s going on, nine times out of ten, they’re probably going to search online for it. Turning to the internet for help is common and hey, that’s probably how you ended up here. As a local company serving Union City, Union City NJ, and nearby NJ areas, our team handles HVAC, air conditioning repair, and broader HVAC services for residential and commercial customers.
Homeowners turn to the Internet for several reasons. First, they want to know if it’s something they might be able to fix on their own. Two, they want to know if it’s something they did out of neglect. And three, they want to get an idea of what’s wrong and how much it’ll cost to fix it. That early research can help determine the issue and point to the right solutions.
It’s great to be a proactive homeowner and to try and understand what’s wrong with your system. However, we hope you’ll leave the necessary air conditioning service in Union to the pros if you realize the “fix” isn’t something as simple as changing the air filter. An AC unit can fail on the hottest summer days, which is why timely air conditioning repair matters.
Let’s go over the answers to the questions that brought you here. Common AC issues often show up during the summer heat and can quickly make your home uncomfortable. Here are 3 common AC issues and the problem, their symptoms, and the likely repair.
Strange Noises
- The symptoms: Strange sounds that are audibly noticeable and bothersome. These can include hissing, bubbling, banging, screeching, metal-on-metal, or any sound that is loud and unusual.
- The likely culprit: When refrigerant is leaking from the system, it’ll produce a hissing or bubbling sound. Banging, screeching, and grinding usually mean there’s a loose screw or a lack of lubrication between moving parts, which can reduce reliability over time.
- The possible fix: For leaks, we’ll pinpoint the source of the leak and seal it, then refill the refrigerant. For a loose component, worn-down parts, or a lack of lubrication, we specialize in fixing these issues by tightening what we can, adding lubricant, and replacing parts when needed to help maintain peak performance and keep it operating smoothly after proper installation and repair work.
Lukewarm/Hot Air
- The symptoms: Your AC is running but your home’s temperature isn’t budging in the slightest, leaving the space uncomfortable when you need cool air most. When you check the vents, you notice the air is lukewarm or downright hot instead of keeping your home comfortable during the summer heat.
- The likely culprit: A refrigerant leak, a clogged air filter, or a malfunctioning compressor in the unit can keep the ac system from cooling properly; these strange noises can also help technicians test the equipment and determine whether the cooling system is still operating reliably.
- The possible fix: If it’s because the filter is clogged, replacing it with a clean one should remedy the issue and help maintain the air conditioning system for peak efficiency and more efficient operation. If low refrigerant is caused by a leak, the fix is to repair the leak before refilling refrigerant, and our team specializes in repair and installation work for AC components and system upgrades. If it’s the compressor, be forewarned that this is a major, costly component in the ac unit, and you may need to replace it to restore warm air balance, lower energy costs, and keep the system performing at its best; for rooms where adding ductwork is impractical, we also carry options like a ductless mini split system.
Leaking Condensate Line
- The symptoms: There’s water pooling around the base of your AC. Your AC might not turn on at all because the sensor has been notified that there’s a problem with draining, and losing cool air during the summer heat can make the entire space uncomfortable and harder to keep the home comfortable.
- The likely culprit: The condensate line drains the moisture that your air conditioning system collects. Sometimes, it can become clogged with dirt, dust, and mold. When it can’t drain, water collects and overflows. Without regular maintenance, this kind of buildup can also reduce efficiency and lead to higher energy costs. Ongoing maintenance helps prevent clogs that can contribute to system failure. Many homeowners choose maintenance plans for scheduled inspections and cleaning. A plan can also give you easier access to expert help when drainage issues return. We also offer comprehensive maintenance plans designed to catch these problems early.
- The possible fix: Try pouring a cup of plain white vinegar into the condensate line to see if that removes the clog. If the clog has caused compressor damage, this can become a costly repair. You may need to replace the AC unit if it is over 15 years old. Replacement is also worth considering if repairs would cost more than 50% of a new unit or if the unit still uses R-22 refrigerant. If installing or replacing a traditional system is impractical, a ductless mini split system can be a good option for spaces without existing ductwork, and we can carry solutions suited to different room sizes and layouts.

Frequently Asked Questions
Question: Why is my air conditioner making strange noises?
Answer: Strange AC noises can point to different problems depending on the sound. Hissing or bubbling may mean refrigerant is leaking, while banging, screeching, grinding, or metal-on-metal sounds can come from loose parts, worn components, or lack of lubrication. A professional inspection can identify the source before more damage occurs.
Question: Why is my AC running but blowing warm air?
Answer: If your AC is running but the air feels lukewarm or hot, the problem may be a clogged air filter, low refrigerant from a leak, or a malfunctioning compressor. Replacing a dirty filter may help, but refrigerant and compressor issues should be handled by a trained HVAC technician.
Question: What causes water to pool around my air conditioner?
Answer: Water around the base of an AC system often points to a clogged condensate line. This line removes moisture collected by the air conditioner, but dirt, dust, and mold can block proper drainage. When that happens, water can overflow and may even trigger a sensor that shuts the system down.
Question: Can I fix common AC problems myself?
Answer: Some simple AC issues may be safe for homeowners to try, such as replacing a clogged air filter or pouring plain white vinegar into the condensate line to help clear a minor clog. However, refrigerant leaks, compressor problems, unusual noises, and worn mechanical parts should be repaired by professionals.
Question: When should I call for professional AC repair?
Answer: Call for AC repair when the issue goes beyond basic maintenance, especially if the system makes loud unusual noises, blows warm air after the filter is changed, leaks refrigerant, or has water drainage problems that keep returning. Prompt service can help prevent bigger repairs and restore cooling more reliably.
