Why Isn’t My Ductless Mini-Split in Walnut Creek, CA, Producing Heat
Discovering that your mini-split isn’t producing heat can leave you frustrated and cold. You may think that isn’t a serious problem, but Walnut Creek, CA, hits the low 40s in the winter. Here are some reasons your ductless mini-split isn’t producing heat and how to resolve the problem:
There’s a Wiring Problem
The mini-split communication wire is one of the most important parts of the system. It’s recommended to use 14-gauge four-conductor wire for most systems. Improper wiring could account for the heating issue you’re experiencing.
Some common signs that your unit wasn’t wired correctly include:
- The system works one day and has problems the next.
- Only being able to make the unit work in some modes.
- Having to replace other parts of the unit often.
- Loud or unusual noises coming from the machine.
- A series of blinking lights or an error code.
Electrical issues can be very dangerous, so you should never try to fix the problem yourself. Call a professional to check the wiring and find the issue.
Extreme Outdoor Conditions
Outdoor temperatures can impact the efficiency of a ductless mini-split. Potential problems to look out for include:
- Snow laying on top of the outdoor unit.
- Strong winds hitting the unit.
- Snow gathering around the base or sides of the unit.
You can resolve these weather-related issues with a few simple steps:
- Place the unit on a stand or wall-mount it so snow can’t gather.
- Have a wind baffle installed.
- If the unit has an optional drain pan heater, have it put in place.
Contact a heating professional, and your home will be toasty before you know it.
A Refrigerant Leak
While it isn’t a common culprit, a refrigerant leak could be responsible for your problem. The refrigerant absorbs heat and helps your system maintain a set temperature.
To determine if this is the problem, listen for hissing or bubbling noises, and look for wet spots near the unit. If you notice any of these signs, have a professional check your refrigerant lines.
Troubleshooting Your Ductless Mini-Split
DIY repairs can be dangerous, and you shouldn’t attempt them on your mini-split. With that in mind, there are a few safe troubleshooting tricks you can try before you call for a repair.
- Check the unit for snow, leaves or other debris.
- Check your circuit breaker to ensure nothing has flipped.
- Replace your air filter.
If you’ve tried all the basics and it still won’t work, it’s time to call in backup. The talented team at Contra Costa Climate Control can handle your heating repair. Book an appointment now to avoid feeling chilly later.
