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.

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.

Great customer service, technicians always on time and friendly. I’ve had my new hybrid heat pump for a few years and Guthrie & Sons are very proactive making sure everything is running smoothly. Very happy in my decision to use them!

Great service!! Jonathan was patient, kind, knowledgeable and extremely professional! I love Guthrie & Sons’ reminder system, notification of the technician enroute, the easy invoice system and immediate emailing of the findings, including detailed photographs of the work completed!! Highly recommend!

Last summer my air conditioner couldn't cool the house in the hottest period of summer. The HVAC team I was working with came in and said the coils were leaking, the unit was 20 years old. I requested quotes from 5 different companies, and the variation of prices was huge. I went with Guthrie and Sons for these reasons:
1. Local Company
2. Family Owned
3. Great presentation, no pressure
4. Good products
5. Competitive pricing
Just installed yesterday, so jury is still out on the system, but installation was thorough and great communication so far!

Carson and Michael were brilliant. The heat pump installation went smoothly, and they are really pleasant and trustworthy fellows. The day after it was installed, I had a plumber at my house. He looked at their work and was impressed. He said it was much cleaner than the way HVAC people usually do it.

First time prospective client of Guthrie and Sons. Very responsive staff in providing updates on my calls. Mario F. came over to check out my existing cooling and heating system and is very thorough and professional in providing necessary information related to repair/upgrades. Pending his quote, my experience with Guthrie and Sons is top notch and most highly recommended.

Updated review: Kareen, Daniel and Michael worked on the AC replacement, relocation of furnace to the attic and replacement of ductwork. Very professional and knowledgeable team in my opinion. Completed the work in a timely and very satisfactory manner.

My experience with Guthrie & Sons has been excellent, and I am pleased to write a very favorable review about it. They replaced three air conditioners and three propane furnaces with new equipment that utilizes heat pump technology. I had met with other companies and I was close to coming to a conclusion, when a friend recommended Guthrie & Sons. He told me that they are hyper focused on customer service from beginning to end.

Their customer service started with the on line completion of a basic information form. Shortly after submitting that form, I heard from Zach who scheduled an appointment at my home.

I had already met with three other HVAC contractors, and for that reason, I had some basic information about the systems available and how heat pumps work and whether propane furnaces should also be installed. I signed a contract on a Friday. By Wednesday of the next week they had completed the installation. Wow.

The installation of one of the furnaces in the attic caused minor damage to the drywall. THEY BROUGHT IT TO MY ATTENTION and told me a drywall contractor would be in touch regarding its repair. Two days later it was repaired.

Since installation, the equipment (heat pumps from Bosch) has been working great and I am optimistic about the future. Meanwhile, their pricing, warranty and terms are far superior to their competitors.

Since this is an unusually long review and so favorable, let me add this: This is my honest, uncompensated opinion. I have no relationship with anyone at Guthrie & Sons other than the contract we executed.

We recently had Guthrie and Sons install a Mini-Split system in our home. The entire process was handled professionally with no issues occurring at any time. The estimator (Vlad) went through options with us but let us evaluate the best solution for us with zero pressure. The installation team (Matthew and Aaron) showed up on time, reviewed the scope of the job, made sure they understood what we wanted, and then proceeded to complete the installation exactly as discussed. They asked for my input as needed so there were no surprises when the job was completed.
They respected my property and made sure everything was left at least as clean was when they arrived. The job was completed on time and as promised and they reviewed the details of the system and its use clearly. I would definitely have Guthrie and Sons do other electrical/HVAC work should the need arise.

I have been in the construction industry in San Diego for over 50 years. I owned my own contracting company for over 40 years. I have seen all levels of customer service in my years. The level of customer service from Guthrie and Son’s is among the best I’ve ever seen and received. Every time I hear anyone asking for a referral for HVAC work I immediately give them your number. When I recommend a company I in essence am putting my name and reputation on the line. I refer them with 100% confidence in the service they will receive. Thank you very much for your legendary service.

We first hired Guthrie and Sons to replace a furnace after comparing proposals from several heating and air companies. They’ve since been back for annual check ups, and today Kareen came to diagnose and resolve an issue with our mini-splits. My experience each time, including today, is that they hire friendly, knowledgeable people who do good work. They’ve never tried to upsell or do anything unnecessary, which is the way it should be. I’d recommend them to anyone who asks.

My AC was not working for seven months. Three other companies tried to fix it with no success. Don’t make the same mistake I did—go straight to Guthrie & Sons! They are absolutely worth every penny.
