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. 

If you need help determining whether a central or ductless system is right for your home, we’re here to help. Our certified technicians will evaluate the layout of your home, discuss your home comfort needs, and provide the perfect solution for you. 

Commercial Ductless Mini-Split Installation

When it comes to your business, you want a reliable and efficient heating and AC system to keep your customers comfortable. 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. 

Commercial HVAC systems are complex and require certified technicians to ensure a perfect installation. You don’t want your heating and AC system to fail during business hours. Contact the experts at Guthrie & Sons Heating, Air & Solar to schedule a free estimate on a new installation.

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.

Having trouble with the remote and to operate our mini split cassette unit. Within 5min Mario had the unit up and running as well as how the unit with remote works efficiently. Mario also went to bat for us to have the condenser mounted on the Guest House rather than in the dirt inches away from our brow ditch.Thanks Mario

Guthrie and Sons installed our heating/AC unit in 2022 and so I called them for their help with an issue I was having. The technician Jonathan came out and checked all of the units (4) and the outside control panel and all is good. We could not replicate the (small) issue and determined it to be an unknown cause. Glad Jonathan came out, all units are now working perfectly. Thank you to Guthrie and Sons!!

I had a really positive experience with Guthrie & Sons. I worked with two techs, Jonathan and Zach, and two people over the phone, Mallory and Makenzie. Jonathan and Zach were super helpful, informative and patient with all of my questions. Mallory and Makenzie were also very helpful, patient and accommodating as they enabled a fix to my heater issue in a timely manner. Would 100% recommend their services!
