Q: What exactly is a ductless mini-split system?

A: Great question! A ductless mini-split is a heating and cooling system made up of one or more indoor units connected to an outdoor unit—no ductwork needed. They’re compact, efficient, and ideal for everything from single rooms to whole homes.

Q: Are ductless mini-splits better than central air?

A: That depends on your home and comfort goals. Ductless AC systems are often more energy efficient and easier to install (especially in older homes), and they let you control the temperature in each room. Central air conditioning is great, too, but mini splits offer serious flexibility, and no ductwork means less energy loss.

Q: Can I use a ductless mini-split system for both heating and cooling?

A: Absolutely! That’s where ductless mini-split heat pumps come in. They deliver cool air in the summer and warm air in the winter—all from the same unit.

Q: How long do ductless systems last?

A: With proper maintenance, most mini-split systems last 15–20 years. Regular check-ups can help extend that life even further.

Q: How often should I service my ductless mini-split?

A: At least once a year—but twice is better. A quick spring and fall tune-up keeps your ductless heating and cooling system running smoothly and helps prevent surprise breakdowns.

Q: What’s involved in maintaining my mini-split?

A: Maintenance includes cleaning filters and coils, checking refrigerant levels, testing electrical components, and making sure each indoor unit is working properly. It’s easy with a Mauzy maintenance plan.

Q: Is it hard to install a ductless mini-split in an older home?

A: Not at all! One of the best things about ductless systems is that they don’t require major renovations or bulky ductwork. We’ve installed mini-split AC systems in homes all across San Diego County, even the most unique ones.

Q: Can I install a mini-split myself?

A: DIY might sound tempting, but trust us—this is one job you want to leave to the pros. Improper installation can hurt performance and even void your warranty. Let Mauzy’s expert technicians handle it.
