FAQs: All About Ductless Mini Splits in San Diego

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.

I had an awesome experience with Wilber from Mauzy! He was on time, super professional, and really took the time to explain what was going on with my plumbing issue. You can tell he genuinely cares about doing the job right. He worked efficiently, cleaned up afterward, and made sure everything was running perfectly before he left. It’s hard to find great service these days, but Wilber and the Mauzy team definitely delivered. Highly recommend!

This was our first experience with Mauzy, having previously bought our furnace from Goettl. Joe A was the technician and we appreciate the good prompt service he delivered for our annual system maintenance. Thank you!

5

Michael was outstanding and professional, a great representative of your business.

5

Evan demonstrated excellent customer communication and partnering over solutions

5

We had a challenging AC leak issue on a relatively new system that was very frustrating and costly. We would pay several hundred dollars to fill up the refrigerant, two different techs would poke around and say they didn’t find a leak and say it’s fine. Then less than a month later we would be down the pounds again and cost us money to refill.

We asked Mauzy send their best guy out to resolve this once and for all so they sent Mike Mittman. Super nice, friendly guy. Very understanding of our frustration. Took him an hour or so to pin point the leak, showed us the leak, demonstrated to us the leaking sound and repaired it, refilled the refrigerant!

Thank you so much Mike!

5

My tech was great. Very nice and did his job. Thank-you.

5

Mac Donalson the electrician from Mauzy (A/C, heating, air, electrical and plumbing) , gave excellent customer service. He was professional, personable, knowledgeable, and truly cared about our home. He was from and gave service with a smile, a true blessing. He gave recommendations and did not try to sell us, but instead help us with preventive solutions to make our home safer. I would definitely recommend Mac . Thank you. Gods blessings

5

My technician Kory, was great. He was very thorough, nice and helpful. Explained everything really well he took pictures and showed me the problem areas. The maintenance price is reasonable. Repair prices are on the high end but that is separate from the services received.

Juan Mendez did an excellent job of relocating electric wiring in the bathroom making room to install a One Day Shower Unit . One quick neat
job ! ! !

Corey came out for my annual heater system check up and was thorough and very nice and left everything nice and clean. It was an equally positive experience when he did the ac check up in Spring. I have a contract to check systems yearly so there wasn’t a charge for the visit. Having the contract makes sure I don’t skip a year a two as has happened in the past!

5

With very rapid response Mac Donaldson helped us with 5 malfunctioning smoke/carbon monoxide alarms. As is always when Mac helps us with repair or project estimates, he is prompt, courteous, skilled and gives clients confidence in the work. We are long term clients because of Mac. Jeff and Marsha

Rigo listened to my issues and was very helpful.

We discovered a water leak in my office and found Mauzy Plumbing (formerly Sherlock) on Yelp. They responded quickly and got Tommy Clementi out to inspect the problem. This led to leak discovery and repair, and we spoke with Tommy about how to best protect our 35-year-old plumbing from future failure (as much as possible, at any rate). This led to a new pressure regulating valve, a whole-home water filter, and a Moen Flo auto-shutoff valve that monitors water flow and shuts the system off if it sees out-of-the-ordinary flow. Not exactly cheap, but we feel it is good insurance. Then we realized our hot water tank was old and losing capacity so we had them replace the old tank with a new tankless on-demand system. We’ve had it for a couple of weeks now and it’s working well. Altogether a very positive experience over several weeks with several different technicians, all of whom were on-time and professional. The options were explained well and all costs were clear up-front with no surprises. Thanks Mauzy – a great job and much appreciated!

Kyle came out for my yearly inspection of my HVAC. He was very detailed about checking everything and very knowledgeable. I would highly recommend Kyle
