Learning how to troubleshoot your mini HVAC split system will help you maintain this system more easily and also alert you when it’s time to call Vese Heating & Cooling for professional help.
CORRECT INSTALLATION
The most common problem with mini-splitters is an improper installation that results in improper charging and/or refrigerant leaks at flare fittings.
The installation requirements in accordance with the manufacturer’s recommendations are very important when it comes to properly troubleshoot these systems.
Sometimes it can be difficult to troubleshoot a ductless air conditioning unit because there is no standard troubleshooting guide – troubleshooting differs from manufacturer to manufacturer depending on the problem. In addition, customers do not keep installation and troubleshooting documents, customers should keep those documents for the life of the equipment. Therefore, sometimes you need calls to technical support. Less experienced technicians usually have troubleshooting problems.
The Refrigeration Issue In The Mini Split Ductless Heat Pump
Modern mini-split systems use R-410A, a refrigerant that is more environmentally friendly than the previously used R-22. In comparison to other refrigerants, R-410A operates at higher pressures, which requires the use of gauges capable of measuring that pressure.
Generally, mini-split units are charged with refrigerant. Nevertheless, if you need longer than usual lineset, chances are that you may need more refrigerant. Each Mini Split System must include a manual which lists the amount of refrigerant needed for each foot of the line you have.
If there is too much or too little refrigerant in the system, the following are few problems:
Insufficient refrigerant
May not dehumidify as supposed to
The compressor of the unit may become noisy
Can’t maintain room temperature
It can only work properly in one mode, but not in another mode when it is in cooling mode, but not in mode.
The system overcharged with refrigerant
The air conditioner may not turn on
The AC may not be able to maintain the temperature
Generally, ductless air conditioning units have the correct line set size, including pipe size, maximum and minimum length, and maximum height difference between outdoor and indoor units. You should never reuse old lineset especially if the system had burnout problems. Because in case of the reuse of the lineset, the lifetime of equipment might decrease dramatically.
Not Proper Cooling
Possibly the most common problem is when the unit is running and little or no cold air comes out from the air conditioner. In most cases, this is due to a clogged air filter. Many experts recommend cleaning the filter at least once a month). Filters can be quickly removed and washed. However, if the filter is difficult to access or the debris cannot be removed easily, it is best to talk to a professional.
Not enough cooling can also be due to low refrigerant levels in the system.
The refrigerant must stay at a specific charge (i.e. level) in an air conditioner that is balanced to the system’s size nevertheless, refrigerant can leak from an AC due to damage, corrosion, and loose connections.
Check the Voltage
If the mini-split system doesn’t work at all, it is possible that your electrical system in your home is not giving proper voltage. Check the circuit breaker to make sure no circuits have tripped, then check the cord and plug for damage. If your remote doesn’t work, make sure it has fresh batteries and try using a button or see if you can manually activate the device using the control panel. When you have checked these possibilities, definitely call a HVAC service technician. The solution to electrical problems is best left to professionals for convenience and safety reasons.
Clean the drain line
Regularly checking the drain line of your HVAC mini-split system will prevent deposits build-up, back up that line, and cause system shutdown due to water damage. Most HVAC officials recommend using vinegar to keep the drain line clean. Generally several times a year you can remove any build-up by flush vinegar through the line. If the unit is not working or leaking through the air handling unit, this is definitely a job for your HVAC specialist. In some cases, it can cause water damage in your home.
Dirty filter or vents
Debris and dust are drawn into the air conditioner every time it calls for cooling. Over time, this dirt and dust can build up inside the filter and vents, causing reduced cooling performance. It’s recommended to check and change the air filter regularly. Alternatively, you can check the air conditioner vents and clean and remove dirt or dust. If you find large blockages, it is best to contact the air conditioner repair service for cleaning. A professional will remove dirt and dust from the entire unit, not just areas you can reach without opening it.
