Benefits of Ductless Air Conditioning
With ductless air conditioning solutions, homeowners will enjoy less noise than with conventional air conditioner systems. It’s also possible for the unit to cool areas that are hard to reach with conventional duct systems extending the comfort level in all areas of the home.
Ductless air conditioning systems and heating systems combine a standard outdoor unit with indoor units that mount on the walls. The units are perfectly suited for the unique weather in San Diego and are some of the most efficient systems available today for both heating and air conditioning.
All In One
Ductless units work for both cooling and heating of the home, providing unlimited comfort from one HVAC system.
Energy Efficienct
Ductless air conditioners and heat pumps are also energy efficient. Because there is no ducting, heat and cooling loss normally associated with traditional units is eliminated. Air loss through ducting can account for up to 30 percent of energy consumption according to energy.gov.
Zone Control
Ductless split systems are great for large homes and small spaces because of their zone control. Homeowners can control heating and cooling in each space separately, increasing efficiency further by not heating or cooling unused spaces. Zone control also allows homeowners to set different climates in each room, which is ideal for households with individuals requiring varying comfort settings.
Smart & Programmable
Ductless split systems can be controlled from anywhere with wifi connection. Like most HVAC systems being manufactured today, ductless systems are smart and can be programmed and wirelessly controlled. Ductless air conditioners also come with remote control operation while homeowners are in the home.
Reduced Noise & Size
Ductless mini split units are incredibly quiet. Homeowners have often found it challenging to find a powerful, yet quiet operating HVAC unit. With ductless systems, the whisper quiet settings will provide home cooling and heating without making a sound.
Additionally, the outdoor unit is more flexible with ductless systems and can be placed in varied locations along the side of the home. They are much slimmer than traditional condensing units, which many homeowners find appealing.
Easy Maintenance
Ductless ac units are easily maintained by homeowners and HVAC professionals. Homeowners can keep the units clear of furniture or obstructions and clean the filters on a regular basis to keep the system running well and improve indoor air quality.
Once a year, just like with traditional units, homeowners should have an HVAC professional service the outdoor unit of the ductless system. Unlike traditional systems, you will only need one annual appointment, since the heating and cooling system is all in one.
Ductless System Maintenance & Tune-Ups
Ductless HVAC systems are ideal for a wide range of applications and offer years of reliable and affordable service if they are installed and maintained properly. Like conventional HVAC units, a mini-split requires regular maintenance and tune-ups for peak performance. Homeowners can handle routine DIY maintenance such as filter changes, but it takes a pro to thoroughly inspect and assess a unit’s health.
A professional tune-up in spring and fall is recommended to ensure your unit is ready to battle the heat of summer and the cold of winter. A well-maintained ductless system is much less likely to break down or require service unexpectedly and is significantly more efficient. Essential maintenance, such as checking refrigerant levels, inspecting electrical parts, and clearing condensation lines, will keep your unit working all season long.
How Ductless Systems Work
Bill Howe takes pride in guaranteeing year-round comfort with a variety of service options that best suit your needs. Our ductless AC service option is an ideal solution for homeowners who lack a central air unit or simply don’t have the room in their home to add ductwork.
Ductless systems work by linking small individual room units to an outdoor compressor. The evaporator coils in the small indoor units are cooled with refrigerant. The warm air in the room blows over and is absorbed by the evaporator coils. Then, the refrigerant takes all the indoor heat to the unit outdoors.
- No ductwork is required (unlike a central AC unit, which is connected by ductwork throughout the home and blows hot or cool air through vents).
- Includes small units placed directly in each room.
- Pulls in warm air and sends it back out as cold air.

Frequently Asked Questions
At Bill Howe, you can choose from various ductless mini-split service plans to help you get the most out of your system. Below, we answer some of the most common questions regarding ductless AC systems.
We recommend scheduling professional ductless AC service twice a year. Regular ductless heating and AC service is one of the best ways to keep your system in tip-top shape. It’s a good idea to schedule ductless heating service before winter and once more before summer.
Scheduling twice-yearly ductless conditioner service keeps your system working at its optimum level. However, you can do your part between services by cleaning the filters and the area surrounding the outdoor unit. With basic DIY maintenance, you can prolong the life of your system.
A ductless air conditioner has a longer average lifespan than conventional AC units. With routine ductless heating and AC services and DIY maintenance, your ductless system can last up to 20 years. Some can last up to 30 years with an exceptional maintenance plan.
