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.

I had my heating and air installed in January 17,2024 and we normally just turn it on when we have company or get together here at the house , it usually blow air but not cold enough and we thought that's normal and when the installation was completed we were promised that someone form Guthrie will call in 6 months for follow up but that did not happen , so now that it has been 7 months that we had the HVAC i decided to call Guthrie to make an appointment to have it check and Rob M came 08/09/24 and i showed him the furnace in the garage and he knew right away that the heating and air was not installed correctly , i am just hoping that this experience does not happen to anybody else and please have Guthrie management make aware of it to support and maintain your " Lifetime Workmanship guarantee to ensure your system holds the same integrity it did from the first day you owned it ."Rob M - Very professional and great customer service .Thank youAser Pineda

Staff was very friendly. However, the technician was not here on time, between 12 and 4, nor was there any communication that he was going to be late until I called and asked. The technician did not come till almost 8pm.

Absolute Lifesavers!If I could give Guthrie & Sons and Zach M. more than 5 stars, I would! San Diego is melting under this heat wave, and my A/C decided to take a vacation. After calling 5-6 different HVAC companies (all of whom acted like I was asking them to perform rocket surgery), Guthrie & Sons were the only ones who came to my rescue.They squeezed me into their packed schedule and sent over Zach M., who arrived like a knight in shining armor—well, more like a knight with an HVAC toolbelt, but you get the idea! Zach was not only super knowledgeable and thorough, but also just an all-around great human being. He patiently explained what was going on, didn’t mind my 20 questions, and worked like a magician on my poor, exhausted unit. The guy probably sweats Freon with how effortlessly he fixed everything!Zach’s combination of expertise and top-tier customer service is what every company should strive for. Thanks to him and Guthrie & Sons, my house is cool again, and I can stop pretending I live in an oven. If you’re in need of HVAC magic, stop looking—Zach M. and Guthrie & Sons are the team to call!

They offered an impractical and useless solution to try and refresh the Freon ($4000) without a pressure test. Freon went up into the atmosphere within a week. Wasted $4000 and still no A/C. Gave them a chance to rectify by applying $4000 to the cost of a new unit. Their cost for a new unit AFTER applying the $4000 credit was still $5000 more than an alternate supplier or HVAC company. Bad judgement and integrity and bad pricing.

Was extremely pleased with entire experience using Guthrie and Sons. Every detail was handled with skill, courtesy, and professionalism; all at a price that meet or beat other quotes we received.Special thanks to Joe Patrick for patiently answering my questions and accurately assessing our needs and existing system ...without trying to oversell.Big thanks also to Wayne and Ben for the great job they did with installation. Their skill and experience were obvious. They were neat and clean from start to finish, not just in leaving our home & yard tidy, but in the details of the installation itself (e.g., solder joints, duct work, wiring, taping, etc.). I also appreciate how personable & articulate they were in explaining our new system, thermostat, options, etc..Finally, a shout out to the office & scheduling staff (Amy and ???). Every call and inquiry was answered quickly, politely, and efficiently.I can't imagine a better experience. We've now had our new AC/Heating system a full 3 months and it continues to work superbly and has been completely trouble free.-----------------------Update Sept 2024: Seven years after initial installation and system still running great. Have never received anything less than superb service from all Guthrie staff. Would highly recommend.

Mario has a strong work ethic along with a high empathy factor. Guthrie should be very proud of Mario as an employee. My wife has fibromyalgia and gets extremely ill due to the heat. Mario took it upon himself to gather a portable air-condition unit so my wife could cool down since she was feeling ill from the heat. I placed my faith in Gothrie&Sons and was rewarded over my highest expectations. Job well done. Thank youPaul Trzinski

Super, from my initial inquiry, called for an estimate, though I needed a new system Vlad came out the same day, he was upfront and honest, went out of his way and instantly identified and repaired the system. They are top notch, thank you!

Our technician Rob was awesome. Very professional. No up sell. Fixed our AC quickly.
Zach came out the same day and offered us some solutions and advice. He even looked at the warranty data for our unit, which was installed by a different company, to see if we could get any of the repairs done for free. He tried to minimize cost to us while maximizing the effectiveness of solutions, and was very friendly.
