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.

Great service.

5

Just had Evan G from Mauzy do an evaluation on the plumbing on my home. The evaluation could not have been more complete.
Every bit of the plumbing was checked. Yes everything was good to go but if there was an issue Evan with his knowledge would not have missed a thing. At least 2 hours to go through all the plumbing. I recommend every home owner to get the same service. It will save on the long run and if there are minor issues you will be made aware. Evan G was terrific.

5

Kory was great and very thorough , thank you

5

Mouzy is hands above any other plumbing/electrical A/C, firm I’ve used in the past, and since I am 80 years old, I’ve used a heck of a lot of them. They are fair, polite, and knowledgeable. I have no idea what More can think of to describe them.
You’ll be happy with them!

Brandon was our technician, and was great about communicating prior to his arrival with an estimated time to be at our home. He was very pleasant, and explained what services he would be providing. During his visit, he was respectful of our property and kept us informed on progress of the work provided. He left things in order and provided a final update on his analysis of our plumbing. Very impressive service.

Joshua was professional and courteous. His detailed description of filtration systems, along with inspection and recommendations for correction of my failed in line water filter were a sell point for the filter I subsequently purchased from Mauzy plumbing. He provided above and beyond service, tightening fixtures and replacing piping and components at no extra charge. He demonstrated how water quality reflected filter performance, which turned out to be what he predicted it would. I was more than satisfied with Joshua’s informed and thorough
service. Thank you.

I should’ve called Mauzy first! Prior to the call to Mauzy I had 2 companies come out to help me with a plumbing issue I had. Let’s just say it got worse rather than better. Finally, Wilber, an exceptional young man to say the least, came to the rescue! Knowledgeable, efficient, and walked me through every step of the process. Pinpointed the problem and had my plumbing issue resolved. Thank you Mauzy for having exceptional employees that know what they are doing! Will continue my services with Mauzy.

I highly recommend Mauzy! Their technician Wilber did an amazing job! He was professional from the moment he arrived. He was respectful, knowledgeable and very thorough. He quickly identified the issue and took the time to explain my options clearly. He made sure everything was cleaned up and working perfectly before leaving which made the whole process smooth and stress-free. Definitely recommend this company and highly suggest you request Wilber!

5

Mauzy plumbing installed a tankless water heater for me in February and they did a superb job. The technician from Mauzy who installed my tankless water heater was Franky. I recently had a question about my system and Mauzy immediately sent Franky back to my home to evaluate the situation. He did a thorough analysis and determined that everything is good. I’m sure all of the Mauzy technicians are excellent, but if I ever have a complicated plumbing problem in the future, I would specifically ask for Franky; he is extremely knowledgeable and thorough and I can’t recommend him and Mauzy highly enough.

5

Mike Kesner was great! Professional, knew what to do to check the issue and was efficient in its resolution.

5

Excellent both times. Technicians were knowledgeable and polite. Respectfull of my house. Top notch service.

5

The Mauzy crew did a great job installing our new cooling and heating system. Alejandro, Chris, and Isaac worked all day to complete the work and were very professional. They deserve a free lunch for their efforts.

Mauzy’s technician, Christian Perez, was absolutely wonderful. He was very personable, professional, knowledgeable, patient and kind.

He made sure everything was clean and working perfectly before leaving.

I recently had the pleasure of working with Joe Annello from Mauzy Cooling, Heating, Plumbing, and I cannot say enough about how great the experience was. From start to finish, Joe stood out for his exceptional professionalism and friendly demeanor, making what could have been a stressful situation feel effortless and reassuring. Joe was incredibly thorough in his work, taking the time to carefully assess and diagnose the issue. It was obvious that he takes pride in his work and genuinely cares about providing the best service possible. His attention to detail was truly impressive, and he made sure everything was checked over meticulously before giving his recommendations. What really set Joe apart was his ability to explain everything he found clearly and in a way that was easy to understand. He never rushed through the details or overwhelmed me with technical jargon; instead, he patiently walked me through his findings and the steps needed to resolve the issue. It made me feel confident and informed about the situation, which I really appreciated. Joe’s combination of friendliness, thoroughness, and clear communication truly makes him a standout technician. If you’re looking for someone who is not only skilled but also goes above and beyond to ensure an excellent customer experience, I highly recommend Joe Annello. He represents Mauzy Cooling, Heating, Plumbing in the best possible way and is someone you’d want working on your home!

Corey Buck checked out our HVAC system today and was quick, thorough and efficient. He was also very courteous and amiable. We appreciate he was on time arriving just after 8 am with a 8-10 am window. Thank you.

5

A water heater breaking & unique older home piping/water pressure situation made what should have been a routine water heater replacement a bit more complex, and Ron, Ryan & Kacey were great in helping us get this quoted and serviced in the same day. I appreciate how communicative Ron was and how flexible Ryan was with our crazy schedules!

5

Chris Sotelo, Alejandro, Eddie and Westin were amazing today. They came to install a new A/C Heater unit and did a great work. They were knowledgeable, careful handling the equipment and did everything in a timely way. Thank you to this crew team!
