HVAC System Monitoring

HVAC System Monitoring in San Diego County for More Control and Fewer Breakdowns

Most heating and cooling problems don’t happen all at once—they usually start small and snowball. As your local Daikin Pro Elite contractor, Guthrie & Sons can monitor your Daikin comfort system remotely to catch issues early, make adjustments that may prevent a service call, and work faster when in-home repairs are needed. Talk to us about our HVAC system monitoring services in San Diego today!

Stay Ahead of HVAC Problems With Remote System Monitoring

We use smart technology for a lot of things these days—our home security, cars, and even refrigerators. Now you can use that same kind of technology to keep an eye on your heating and cooling system’s performance! Guthrie & Sons Heating, Air & Solar is a certified Daikin Pro Elite contractor offering HVAC system monitoring services right here in San Diego, California.

If you already use the Daikin One Home app to control your thermostat, you can give us permission to remotely monitor how your system is running through the Daikin Cloud. This means we’ll receive alerts from Daikin on your system’s diagnostics so we can identify issues faster and get them taken care of sooner. In some cases, we can even adjust your system remotely without setting foot in your home!

If you're thinking about upgrading to a Daikin One thermostat or a new Daikin heating and cooling system, we can walk you through your options and handle the setup for you. Keep reading to learn how everything works, and feel free to contact us anytime to get started with HVAC system monitoring in San Diego, California.

It All Starts With the Right Thermostat

To use Daikin One Cloud Services, your system needs a compatible thermostat. These HVAC thermostats connect to the Daikin Cloud, giving us the ability to monitor and adjust your system remotely:

Daikin One+ Smart Thermostat: This model offers full system control with advanced scheduling, detailed alerts, and full monitoring features to help keep your system running smoothly.
Daikin One Touch Smart Thermostat: A simple touchscreen design that’s easy to use while still allowing for full remote monitoring and adjustments when needed.
Daikin One Lite Connected Thermostat: A streamlined option that still provides cloud connectivity and core monitoring features for basic system management.

If you don’t have one of these installed yet, we can take care of the installation for you. If you already have a compatible thermostat, you're ready to get started with HVAC system monitoring!

Worried About Your Data and Security? You’re Always in Control

When you enroll in Daikin One Cloud Services inside the Daikin One Home mobile app, you’re always in charge of what we can see and do. You decide how much access to give us—whether it’s simply viewing system data, making remote adjustments, or full access to help us fine-tune things when needed. You can also allow temporary access when service is required in order to keep things limited.

Your personal data is private and fully protected, and you can update or turn off access anytime. Just like the smart devices and apps you already rely on, HVAC system monitoring simply helps you and our team work smarter—not harder—to keep your heating and cooling system energy efficient and effective.

Benefits of HVAC System Monitoring for Your Heating and Cooling Equipment

It’s so easy to overlook little changes with your HVAC system. The air feels a little off, the system runs longer than it used to, or the energy bill slowly creeps up—but everything still "works," so you don’t think much of it. Meanwhile, small issues are building behind the scenes that can eventually turn into bigger repairs or full breakdowns. And if it’s a rental or vacation property, you may not know there’s a problem until it fully stops working.

That’s where remote monitoring for HVAC systems makes all the difference. It keeps an eye on things 24/7, catches small problems early, and helps us step in before you're facing bigger, more expensive HVAC repairs or possibly even a full HVAC replacement. Here’s more information on these benefits:

Most HVAC problems start small and build over time. With system monitoring, we’re able to spot those issues before you even notice something’s wrong. We see changes in how your system is running and fix problems early, so you don’t end up with a full breakdown or big repair bill.

Catching minor problems early almost always costs less than waiting until something fully breaks. A simple sensor fix or adjustment today can prevent much more expensive repairs down the road. Monitoring helps you stay ahead of costly breakdowns and keeps more money in your pocket over time.

Since we can see how your system is performing ahead of time, we often know what’s wrong before we even show up. That means we bring the right parts, make the repair faster, and get your system back up and running with fewer visits and less back-and-forth.

Many small adjustments—like tweaking your thermostat schedule or making minor system changes—can be handled remotely. We can often fix small issues without even stepping inside your home. That saves you time, avoids scheduling headaches, and keeps your system running without interruption.

When your system isn’t running right, it has to work harder to keep your home comfortable, and that means higher energy bills. Monitoring helps keep everything tuned and running smoothly, so you stay comfortable while using less energy.

Small issues put extra strain on your HVAC system over time, wearing it down faster. By catching problems early, monitoring helps prevent that extra stress and extends the life of your equipment, so you don’t have to replace it sooner than you should.

How to Get Started (It’s So Easy!)

Getting started is simple and takes just a few minutes. First, make sure your Daikin One Home app is installed and updated to the latest version. Then contact Guthrie & Sons to enroll in our San Diego HVAC system monitoring services. Here’s what happens next:

We’ll send you an invitation to activate monitoring.
You’ll receive a notification on your phone.
Select the location you want monitored.
Choose your permission level.
Done—you’re connected!

We’re always here if you have questions or need help. The convenience and cost savings are worth the few minutes it takes to get started!

Frequently Asked Questions

Our HVAC system monitoring works specifically with Daikin equipment that uses a Daikin One compatible thermostat. As a certified Daikin Pro Elite contractor, we’re fully trained and authorized to set up and support this technology. If you’re not sure whether your current system qualifies, we’ll take a look, confirm compatibility, and walk you through your options.

Your heating and cooling system keeps running normally even if your internet or power goes out—it doesn’t affect basic operation. While your system is offline, we won’t be able to monitor or receive updates. As soon as your connection is restored, system monitoring automatically picks up right where it left off without any extra steps from you.

No, you stay in full control at all times. You decide exactly how much access we have, from view-only to full remote adjustments, and you can change or stop access whenever you want. We only see and adjust what you allow, and your personal data stays protected through Daikin’s secure platform.

Yes, our HVAC system monitoring helps us spot issues early, but it doesn’t replace the need for HVAC maintenance services. You still need annual tune-ups to clean your system, check refrigerant levels, inspect safety controls, and ensure everything keeps running efficiently. Remote monitoring helps us identify and fix issues faster between maintenance visits.

Professional from beginning to end

Vlad came out to provide an estimate and was able to size an HVAC system that worked well for my house.

They installed it quickly, without issue and helped me set up an app on my phone to control.

The system is working great to heat and cool my house and is whisper quiet.

Highly recommend going with Guthrie and Sons if you want a high quality experience for large and important purchases.

Our two old furnaces needed replacing and so we contacted Guthrie & Sons because of their good reputation. They sent Zach the next morning. He quickly verified that our two furnaces were beyond repair and Guthrie could supply and install suitable replacement funaces. He also suggested and explained alternative solutions, but we eventually decided to go ahead with furnace replacement. As soon as we notified Guthrie & Sons of our decision they arranged for Cristian and Pablo to come to our house the next day. They did a good job, explained clearly how to operate the new furnaces and thermostats, and were respectful of our house.

Daniel was quick and professional. Fixed our AC problem in an hour and the price was very transparent and beyond fair. Didn’t push the subscription maintenance service, simply said it would be a good idea due to the age of our unit. Highly recommend!

We had to replace a thermostat that had gone bad. In the old days, I could do it myself. Now, though, the programming of the thing requires technical knowledge that I don’t have. The Guthrie guy that did the job was courteous, professional, and as fast as anyone could be. This has been our experience with Guthrie & Sons for every repair, retrofitting, and equipment replacement that they’ve done for us over quite a number of years now.

Carson Snyder and co-worker (Pablo?) did a great job on the installation of the mini-split cassette. They're hard working, they clearly knew what they were doing, polite, cleaned up afterwards, true professionals. I'd gladly recommend these two gentlemen. However, the Company was not good at keeping me informed although I mentioned to the salesman up front that I was information driven. They were short on details and communicated seldom. Anthony did tell me about the government program available that reduced my cost. I wouldn't have known about it if he didn't mention it. The City did approve their work and signed off on the permit which is an indication of the job done right. I think the Company can improve their customer service

Very pleased with the service we received from Guthrie & Sons! Our AC system needed to be replaced after a huge leak. The tech that came out for diagnosis, Mario, took the time to explain the issue to us, as well as our options for repair. They came out on a Saturday to diagnose and it was fixed the following Tuesday. Matthew was the worker that completed the repair and he did an excellent job. Pricing was reasonable. Much more reasonable than the first company we had come out to take a look. We upgraded our system and our SDG&E bill has already gone down. Highly recommend!

Very knowledgeable and professional. Quoted product was high quality and fair pricing. I highly recommend We ended up not going with them only due to the fact we were also getting Solar and ended up going with one company for our project but I would definitely do business with this company in the future if we need it!

We had Guthrie and Sons replace our 50 year old house heater with a heat pump. We are very satisfied with the installation performed by Matthew and Andriy. We were impressed with the detail of their work. They paid particular attention to the required sealing and insulating of the system. Even the HERS testing inspector was impressed with their work. We were also impressed by their professionalism and honesty. They gave us an unexpected partial refund off our signed contract.

We have been using Guthrie & Sons for 3 years and I really can’t say enough good things about them. Our technician Mario was incredibly helpful with our most recent AC issue. He spotted the problem quickly and was very knowledgeable when explaining what was happening. I appreciate their honest and fair pricing and would recommend to family and friends. Glad to have an honest company especially with all the price gauging company’s out these days.

We were incredibly impressed with the prompt and professional service! We called on a Saturday morning, and within just a few hours, a technician was at our home. With the recent heat, getting our AC back up and running was a top priority—and they delivered! Mario clearly explained our options and provided a hassle-free solution that was both quick and effective. The repair was completed shortly after we gave the go-ahead. We’ll absolutely be using them again for any future HVAC needs. Highly recommend this company for their affordability, efficiency, and friendly service—we’re already telling our family and friends! Thanks again Guthrie & Sons!

We were very happy from start to finish. Vlad did a great job in helping us decide what would be best for our house and our needs and the installation crew were the very best. Thank you Guthrie and Sons for a job well done.

Last summer, I used Guthrie and Sons to replace my heating system with a new one and added an air conditioning unit. We also added two different zones in the house to be able to turn the system on independently from one zone to another. From the first contact to the six month maintenance visits, everything has gone smoothly. There were a couple of hiccups, but the company is very responsive and I have never had an issue with them not promptly responding and taking action to figure out and solve any problem. I highly recommend this company.

Guthrie & Son's did an amazing job on our new AC units. From sales through install they were all knowledgeable and helpful. They were very quick to get us all setup and when our home posed some unexpected issues they were able to pivot quickly and resolve them. I'd highly recommend them!

Had use Guthrie in the past for HVAC service, this time had them install a solar attic fan and additional vent. The service, as it had been the first time, was professional, polite, and on schedule. Pricing was fair (and consider that they offered a repeat customer discount without having to be asked). Would be happy to use them again when the need arises.
I offer 4 stars because I'm not a grade inflation sort. Three is sufficient, four is better than average. Five is reserved for knock my socks off amazing in ways I didn't expect - doesn't happen very often.

We had central heat and air put in two a year and a half ago. We've need to make a few adjustments to airflow to rooms since then. Each time, they are onsite withing 1-2 days and have resolved the issue each time. Their team is professional and incredibly friendly and knowledgeable. Very happy we went to Guthrie & Sons.

Mario was knowledgeable and courteous. He made sure our system would be sized right and that our existing ductwork was able to support the new system. The install team were prompt and efficient. They installed drop cloths and cleaned up inside and out after the job. So far I’ve been very happy with the work Guthrie and Sons have done for us.

Great local family business. And you actually get a live person when you call... And the technician was great and they come out quickly. No up selling too. He gave me two different price options on fixing my problem... band aid cheaper way or replacement. Great service.

Jonathan recently inspected the HVAC systems at both my front and guest houses, and I couldn’t be more impressed with his service. He was thorough in his assessment, clearly identifying areas of concern and explaining the recommended repairs in a way that was easy to understand. What stood out most was his honesty and patience—he took the time to answer all my questions without rushing, and I genuinely felt he had my best interest in mind. If you're looking for someone who is knowledgeable, professional, and respectful of your time and property, I highly recommend asking for Jonathan.

If you’re dealing with an AC issue, Mario is definitely one of the best! He quickly diagnosed the problem, worked efficiently, and provided a thorough solution. His expertise and professionalism were clear throughout the entire process. Highly recommend Mario for anyone looking to resolve their AC issues with a reliable and skilled technician.

Guthrie and Sons has provided great service. There are many HVAC companies in San Diego to choose from. They provided a very reasonable estimate for replacing our two AC systems. Once we said yes installation happened within days. It was a quality install. They answer the phone quickly when I've had questions. Happy to refer them to others.
