No Ducts? No Problem: An All-in-One Heating & Cooling Solution

If you have an older home or your home’s layout doesn’t allow for ductwork, a ductless mini-split is the perfect solution for your heating and cooling needs. Ductless mini-split systems consist of an outdoor unit connected to your indoor units, which are installed in various rooms of your house. These convenient, multi-zone systems allow you to individually control each room of the house, making it an ideal and energy-efficient solution for many San Diego homeowners.

Residential Ductless Mini-Split Installation

When you’re looking for a heating and cooling system, a central split system might first come to mind. But, what if the layout of your home doesn’t allow for ductwork to be installed? The solution is easy – a ductless mini split system. Ductless systems allow you to heat and cool your home and gives you climate control for each zone.

Whether it’s in a free-standing building or in a shopping center, depending on where your business is located, your building may not have the necessary configuration to install a central split system with ductwork.

A ductless mini-split is the ideal solution. Install a zone (also known as a head unit) in each room of your business, allowing you to control the climate of each room individually. Ductless systems both heat and cool, so no additional heating or cooling units are needed.

How Do Ductless Mini-Splits Work?

Mini-split heating and cooling systems work without needing ductwork. These types of systems consist of two separate units: an outdoor compressor and an indoor unit.

The indoor unit is responsible for introducing cool and conditioned air around the installed space, and the outdoor unit throws the absorbed heat out into the external atmosphere. The indoor and outdoor units are connected through a small hole in the wall.

One of the major benefits of a ductless system is that each indoor head unit (also known as a zone) can be controlled individually.

Ductless Mini-Split Benefits

HIGH-EFFICIENCY 

Mini-split systems are typically more energy-efficient than central split systems. Many mini-splits boast high SEER ratings. A SEER rating is an industry standard for measuring the efficiency of air conditioners.

The SEER ratings for mini-split systems usually range between 18 and 30 SEER. Systems 16-SEER or greater are considered high-efficiency. 

NO DUCTWORK NEEDED

The beauty of ductless systems is that no ductwork is needed. Instead, they use copper line sets to run the refrigerant to the indoor units. 

The lack of ducts makes these ventless air conditioner systems an especially smart choice for when installing ductwork would be too costly or unnecessary. Mini-splits offer an easy workaround.

ZONE CLIMATE CONTROL

Multi-zone mini-split systems allow you to keep each zone at a different temperature, giving you the power to control the temperatures throughout your house easily and exactly the way you want.

WHISPER QUIET

Ductless mini-split systems have sound ratings as low as 19 dB for the inside unit. With sound ratings that low, they can operate quieter than a whisper. This allows you to stay comfortable without being distracted by annoying noises.

Anthony was very professional and communicative. He was easy to work with in setting up my hear pump installation project. I really appreciated the fact that he wasn't pushing a "hard sell" as some representatives from other companies did. When I had questions an needed quote options he was super-responsive and helpful. Great experience!When Carson, Isaiah, and Israel came your to perform the work, they were punctual, friendly, and respectful. When I expressed concerns or had questions, they addressed them immediately and effectively. Their work was outstanding, the job looks great and the system works well. I have already recommended Guthrie & Sons to other people.Thanks, again, for everything.

The removal of the old direct Heating and ducting went without a hitch. The installation of the new air conditioning and heating unit went very smoothly and I was impressed with every one of the workers. They were friendly and very knowledgeable. They were well equipped to deal with any process problems. I give five stars for this group.As part of the installation contract, Guthrie and Sons sent a worker named Wayne to replace the filter and check our air conditioning condenser. He was friendly and knowledgeable and even slipped on the covers over his shoes as he came through the house. The work was performed very quickly. Another five star performance by Guthrie and Sons.Zack visited today for yearly maintenance. Filter changed out and the unit is working optimally. We'll done.Daniel, this morning, replaced the filter and verified the furnace is in working order and providing proper heat throughout our home. Another skilled and friendly 5 star visit.

Your technician, Jonathan Santana was awesome. My husband was not home and Jonathan was very understanding. Even though there was a mix up with the service connection from Rheem, Jonathan assisted without hesitation. His help made my follow up conversation with Rheem much more productive. Please thank Jonathan for me.Best regards, Lisa
