Air conditioners require diligent maintenance, or else they start to develop real problems. One of the most common air conditioner repair issues we encounter is a leak – a coolant leak. It can happen for several reasons, but none of the root causes are easy to identify.
With that in mind, Hawk Air & Mechanical LLC provides this guide on how to detect leaks in your AC system. If you’d like to know more or get leak solutions, you can also contact us and schedule certified AC repair in Vero Beach, FL!
Signs You Have a Coolant Leak Plaguing Your Vero Beach Home
If you notice any of the following signs in your Vero Beach home, you’ll want to contact a professional to fix the coolant leak and top-off your system before other problems emerge.
No Cold Air
If you want to know how to detect leaks in your AC system, the main sign to watch for is a lack of cold air. Your air conditioner needs an adequate amount of coolant in its coils to effectively cool the air. Without it, the vents just end up spewing lukewarm or hot air.
Are your air conditioner’s vents blowing hot air? Does the room temperature not match the thermostat? Check your coolant levels.
Hissing or Gurgling Sounds
Hissing and gurgling coming from the air conditioner are tell-tale sounds that your unit’s coolant lines have sprung a leak somewhere. Is it a pinhole leak? The pressure may push the coolant fluid out rapidly, creating that hissing or whistling.
Sometimes, experts can pinpoint the leak location just by following these sounds.
High Electricity Bills
Another method for how to detect leaks in your AC system is monitoring the electricity bill. When coolant levels dip, your cooling system works much harder, which draws more energy. Your energy bills will start to skyrocket while the unit’s performance doesn’t change or even gets worse.
Repairing this refrigerant leak should optimize your system and reduce its running costs.
Strange Smells
Air conditioning coolant is naturally colorless and odorless. However, for safety’s sake, air conditioner manufacturers will often add artificial dyes and scents. This helps homeowners and technicians identify coolant leaks before they become a problem.
Coolant fluid usually has a semi-sweet, chloroform-like odor. It’s yellow, pink, or another vibrant color so that it’s easily distinguishable from condensation.
Professional Methods for Detecting Coolant Leaks
How do you detect leaks in your air conditioning system? The professionals have a few favorite methods, which we describe below.
Use a Leak Detector
An electronic leak detector reads the atmosphere to tell you the concentration of coolant fluid around. Coolant detectors work by slightly heating the air, turning ambient coolant molecules into ions, in which the infrared sensor can detect an electrical current. An alarm triggers if the resistance changes, so to detect leaks, the technician looks for spots where the potential coolant concentration is the highest.
The technician places the unit at one end of the line and slowly draws it across the entire length. The device should beep and light up when it detects coolant.
Use UV Dye Detection
Another possible option is colored or UV dye added to the coolant fluid. Coolant is naturally colorless and odorless, but dyes and scents could make any leakage more obvious.
Many manufacturers already add dyes to their products to alert homeowners to leaks. These coolant dyes tend to be vibrant pinks, yellows, and blues. UV dye glows under a black light.
Use Soap Bubbles
Pinhole leaks on coolant lines are sometimes too small to see. If so, technicians might advise trying the soap bubble method to find leaks. Mix a small amount of soap in a spray bottle with some water, spray the pipe and around the connecting joints and watch for bubbles forming.
Some leaks are so tiny they won’t create bubbles, so this isn’t an effective standalone method of coolant leak detection.
Use an Expert’s Services
The most effective way to determine whether you have a coolant leak or some other air conditioner-related problem in Vero Beach would be to contact a professional for pressure testing. Something like a nitrogen pressure test can effectively identify even the smallest coolant fluid leaks.
The advantage of getting experts in is that they can also inspect your coolant lines and top off your system within state regulations.
