Heating and Cooling San Diego with Ductless Mini Splits
At Carini Home Services, we specialize in mini split installation, mini split repair, and maintenance across San Diego County. Whether you need zoned comfort for your home, office, or a converted garage, or a new ADU, our team delivers custom energy-efficient solutions for every job.
Mini splits—also known as ductless heat pump systems—are ideal for homes without traditional ductwork like craftsman homes. They’re quiet, sleek, and incredibly efficient. Best of all, they offer both heating and cooling in one system. Cooling only mini splits also exist, but are not recommended since labor costs are the same and they have less energy savings than a heat pump mini split.

“First of all this was a unique project. House boat. I was very limited on options and decided to use Carini Home Services for my mini splits. Absolutely fantastic. This project could have gone sideways quickly, but for the knowledge, professional attention, and dedication that Anthony demonstrated I’m a happy customer. Great outfit. If you are thinking on going with mini splits do not hesitate to reach out to Anthony.”
-Orlando A.
“John, the design specialist, was the most thorough of any of the potential providers of our mini splits. He took the time to learn of our needs and to study how to get the best system for us. Service, from both the office and the crew, was quick and well-accomplished. Thanks.”
-Bill M.
“Carini has continuously given us great service and great products. We had 4 mini splits installed in Feb of 2018 and every rep and technician has been courteous, extremely knowledgeable and patient answering all questions and explaining every aspect.”
-Amy K.
“Installed 2 mini splits in my home. I got estimates from competitor #1, competitor #2, and Carini. Carini by far was the best onsite presence. Knowledgeable and forthright, I never felt like Carlos was upselling or was talking around a complex subject. He was also the only one out of the 3 to tell me about available rebates. That made it a no-brainer. I also didn’t appreciate all the followup emails and calls from competitor #2. Top quality work and dependable followup, without pressure.”
-Jason O.
“Best Experience Ever. We live in the San Carlos area in San Diego. We have made it without AC in our home for 35 years but, with our increasingly hotter environment, we finally made the decision to add it when we needed a new furnace. Our home was built in the late 50’s and still had it’s original duct work. It also has 2 additions that had no ducts at all making our HVAC project somewhat challenging. Carini HVAC was recommended to us by a realtor friend late in our “getting estimates” process. I was already exhausted by the process but couldn’t pass on Carini after getting such rave reviews from our friend! I also researched Carini HVAC on Google, Yelp and the BBB and found only positive ratings in all regards. The Carini HVAC technician who completed our estimate, Bowen Smith, was courteous, knowledgeable and creative. He had solutions for our HVAC needs that no other local HVAC company technician had even considered.”
-Fred M.
Signs of a Broken Mini Split
Being vigilant about the functionality of your mini split can help catch problems early, preventing further damage and premature replacement. Some telltale signs that your mini split system needs a checkup include:
- Unusual Noises: If your unit starts making hissing, gurgling, or buzzing sounds, it could point to refrigerant leaks, blockages, or electrical issues.
- Reduced Efficiency: A noticeable drop in cooling or heating performance, with some rooms not reaching the desired temperature, suggests potential problems with the system’s components.
- Increase in Power Bills: An unexpected surge in your monthly statement can signify that your mini split is working harder than normal, often due to underlying issues like leaks or mechanical corrosion.
- Visible Ice or Frost: Ice or frost formation on the outdoor unit, especially during the cooling season, can be a sign of refrigerant issues or airflow problems.
If you’re experiencing these or any other issues, even if they are minor, it is better to be safe than sorry. Call the pros at Carini to inspect your ductless mini split system and get it back in working order.

Types of Mini Split Air Handlers
Additional Information
Ductless cooling and heating systems are becoming increasingly popular in San Diego thanks to their extremely flexible design and exceptional energy efficiency. Mounted ductless units are an excellent solution for tight spaces and structures where a different temperature is desired in each room – not to mention the extremely efficient heating and cooling capacity of ductless mini-split units.
Additional Information
These universal mini-splits can be mounted on the ceiling or floor, which provides maximum flexibility in tight spaces. Universal floor/ceiling mini-splits provide powerful heating and cooling that is effective in both residential and commercial environments. They’re great for garages, room additions, and offices as well as for retail and light industrial settings.
Universal floor and ceiling systems are especially popular in the the older homes of San Diego, California where options are limited for installing central air conditioning systems.
Additional Information
Large capacity ceiling-mounted systems are attractive, super quiet, and an extremely efficient solution for heating and cooling spacious areas or high customer traffic zones where plenty of fresh air is a priority. You can see ceiling-mounted mini-split systems installed in businesses all around San Diego.
Additional Information
Ductless mini-split floor mount systems are a perfect solution when it’s time to upgrade from traditional floor radiators. Ductless floor units can be installed in the same position as an old radiator, but they occupy much less space. Floor mini-splits are also perfect for rooms with a lack of free wall space like kitchens and rooms with large windows. Mini-split floor units fit under most standard-sized windows and are twice as efficient as a radiator at half the size. Floor-mounted mini-splits are perfect for historic homes in San Diego.
These types of units are typically mounted on a wall near floor level. Multiflow vanes blow air upward and downward simultaneously for maximum even air coverage – while also heating or cooling rooms much faster than floor mounted units from other manufacturers.
The floor unit is available in multiple capacities and is Energy Star Certified, which means that these systems are at least 15% more energy efficient than government standards. They can be controlled by wireless remotes, and their flat, stylish design looks great in any room.
To accommodate various installation set-ups, a two-block structure includes optional wall recessing capabilities. And its symmetrical design results in a low profile air inlet and removable base section for easy cleaning and maintenance.
Slim Duct
Additional Information
Slim duct mini-split systems are ideal for heating and cooling diminutive rooms and areas like small offices, workspaces, and utility rooms. Slim duct mini-splits are probably the most compact and quiet heating/cooling unit available. And when the outdoor temperature is perfect – which is often the case in San Diego – you can use the slim duct system to intake fresh air into interior rooms. The unit can be easily concealed in a wall or ceiling.

The unit can be easily concealed in a wall or ceiling.
Slim duct-type mini split systems are extremely versatile. To the home or business owner, they look just like a traditional heating and air conditioning system with familiar vents or “registers.” They can be installed in attics above rooms or in crawl spaces under structures.
Slim duct systems can also be combined in “zones” at a home or business, with wall units, cassette systems and other combinations of air handlers, all connected to a single outdoor condensing unit. Each zone can be turned on or off independently, maximizing energy usage.
Additional Information
Ductless compact cassette mini-split systems are remarkably discreet. In most cases, compact cassettes units are mounted flush with the surface, often the ceiling – so that no space or light is sacrificed in the room. Compact cassette mini-split units are designed to a standard size specification and fit perfectly in most standard ceiling panel configurations – just like we recognize from office spaces around San Diego.
Ductless mini-split cassette units are an ideal solution for heating and cooling large rooms or rooms with cold/hot spots that also have limited floor or wall space. Cassettes can be mounted in standard drop ceilings or in a regular ceiling when sufficient attic space above is available. Mini-split cassettes are an outstanding solution for both commercial and residential applications in San Diego.
Ceiling cassettes are exceptionally versatile, finding their way into both consumer and commercial installations. We’ve seen them complementing dens, kitchens, bathrooms, granny flats, nurseries, man caves and craft rooms with a variety of home design styles; and we have two side by side mini split ceiling cassettes in our office conference room. When the room holds a few people, one unit can cool or heat the entire room; and when the room is packed with lots of heat producing bodies, we’ll switch on the second unit to accommodate however many people are in the room.
It’s simple to set up mini split ceiling cassettes, by adjusting vents with a handheld remote control. Vents can be adjusted on all four sides to direct the airflow to exactly where it’s required. Each unit comes with advanced filtration options to create cleaner and fresher air in any room where it is installed. And besides using the simple remote control, you can remotely monitor cassette units from a smartphone or tablet.

Ductless multi-zone mini-split heating/cooling systems allow maximum customization of climate control. With a multi-zone system it is possible to precisely control temperature in each room based on what is needed in a particular moment. Save heating or cooling energy when the room is not occupied. Multi-zone systems are ideal for multiple rooms that have different climate control requirements at different times. A perfect solution for San Diego.
Ductless multi-zone mini-split heating/cooling systems allow maximum customization of climate control in homes and office environments. With a multi-zone system, it is possible to precisely control temperature in each room based on what is needed in a particular moment or based on the number of occupants that could be in a particular room. When the room is not occupied, the heating or cooling can be reduced to save energy. Multi-zone systems are ideal for multiple rooms that have different climate control requirements at different times, making a multi-zone mini split a perfect solution for San Diego.
Depending on the size of a home, office or other commercial application, multi-zone mini splits typically employ one or more outdoor condenser units that deliver both heating and air conditioning without the need for a separate furnace. The outdoor unit or units can be placed alongside a house, on roofs or patios, or placed on special outdoor shelving that can be attached to the outdoor walls of a structure. Each room then can have the same or a combination of different indoor “air handlers,” that distribute the warm or cool air in each room, without the need for traditional ducting. For example, applications can be configured to use wall units in some rooms, ceiling cassettes in another, and concealed “duct-type” units in other rooms. Each of these room air handlers operate off one or more of the outdoor units, and can be controlled individually or in zones that are designed by our Design Specialists for maximum energy savings and peak efficiency.

Frequently Asked Questions: San Diego Mini Split
What is a ductless mini split system?
A mini split is a type of HVAC system that doesn’t require ductwork. It uses an outdoor condenser and one or more indoor air handlers to cool or heat specific zones of your home.
Are mini splits energy efficient?
Yes! Mini splits are some of the most energy-efficient HVAC systems available. Because they offer zoned control, you can cool or heat only the rooms you’re using, reducing energy waste.
Can I install a mini split in just one room?
Absolutely. Mini splits are perfect for single rooms like garages, home offices, or additions. You can also link multiple indoor units to one outdoor unit for whole-home solutions.
How long do mini splits last?
With proper maintenance, mini splits typically last 15–20 years. Regular cleaning, filter replacement, and professional tune-ups can extend their lifespan.
Do mini splits provide both heating and cooling?
Yes. Most ductless mini split systems are heat pumps, which means they can both heat and cool your space year-round, making them a great option for San Diego’s climate.

Yes! Carini Home Services helps homeowners take advantage of available local utility rebates and federal tax credits when installing high-efficiency mini split systems.
