Help Your Mini Split Stay at Its Best With a Maintenance Membership

Help Your Mini Split Stay at Its Best With a Maintenance Membership

Ductless systems cool—and heat!—your home, and they're often doing it for days or weeks at a time. That's a lot of runtime, a lot of dust moving through the system, and a lot of wear on important components. Over time, performance naturally starts to slip. It happens with HVAC equipment, cars, appliances, and just about anything mechanical. That's why annual maintenance matters so much. It helps keep the system clean, efficient, and less likely to surprise you with an expensive repair.

We highly recommend scheduling ductless mini split maintenance in Poway with us each year. Or, for even more convenience, you can join our USA Membership and let us help keep everything on schedule. Members enjoy automatic reminders, priority service, repair discounts, and other valuable perks throughout the year. Talk to our team about what our maintenance plan can do a) for the ductless AC that you’re planning to install or b) the one that you already have!

Frequently Asked Questions

That depends on the system. Some mini splits are designed for a single room, while others can support five, six, or even more indoor units connected to one outdoor unit. During your consultation, we'll help determine how many zones make sense based on what you’re wanting to do and how you plan to use each space.

The cost depends on the size of the space, the number of zones, and the equipment you choose. A single-zone system for a home office or ADU will cost less than a multi-zone setup serving several rooms. We provide free estimates so you can compare your options and understand the pricing before making a decision.

Most mini splits last between 10 and 15 years, and many reach 20 years with proper maintenance. Factors like installation quality, usage, and yearly tune-ups all play a role in system lifespan. Keeping maintenance on schedule is one of the best ways to get the most life from your equipment.

Start by looking at efficiency ratings, warranty coverage, system capacity, and the reputation of the manufacturer. It's also important to choose equipment that's properly sized for your home. As a certified Daikin installer, we can help you compare options and find the right fit.

Very powerful. Modern mini splits can easily cool large living areas, multiple rooms, and even entire homes when designed correctly. Many people are surprised by how quickly they cool a space, even during those hot Poway afternoons when temperatures climb into the 90s and higher.

I am very pleased with the service I received for replacing my furnace in my second story condo. This company really tries to please their customers, which is rare these days. Matthew and James were pleasant, knowledgeable and patient with my questions. The office was great about staying in touch regarding date and time to expect the technicians and providing the number to call for questions. I sam so happy I chose this company to do the job.

I was told by a couple other companies that I needed to replace my system. Vlad came out and made sure that my old system actually needed to be replaced and found it could be fixed for a fraction of the price. I appreciate the honesty and would definitely recommend. Edit the technician came out and made the repairs. He did a good job of explaining the situation and giving a couple options.

Have dealt with Guthrie & Sons regularly for more than 12 years. They are super good in every way re: heating and A/C. Special shout-out to their service man, Mario F, who checked out our systems yesterday. He was extraordinary and really helped us on several issues we noted, and a couple of issues he brought to our attention. Kudos!

We had Rob from Guthrie & Sons come out to repair one of our A/C units. Rob was very friendly and professional. Rob resolved the problem quickly.
As far as price goes, I paid a higher flat fee 12 years ago from one of the larger local companies. I'm very impressed with pricing and quality of work.

I highly recommend Guthrie & Sons and Rob.

Guthrie & Sons has always been super professional and knowledgeable about our system. They did the install a few years ago and have continued to maintain it for us. This year we noticed that our system wasn't performing as well, so when Wayne came out, he noticed a likely leak and was back 2 days later to find and fix it. He was quick, professional, and just extremely nice! 100% recommend.

Called one of the "big guys" in town and the estimate to do what needed to be done to diagnose my problem was nearly 1/2 the cost of the system when I purchased it and had it installed 5.5 years ago, I found Guthrie & Sons and they came out the same day and did the same work for 1/4 the price I was quoted for the same exact work! Daniel was friendly, honest and quickly got my system working as expected. I even purchased the service plan so I don't have future problems. I highly recommend these guys, they were awesome, don't get ripped off call Guthrie & Sons!!!

Matt and Bryan are truly the A-Team! Their teamwork was outstanding and the workmanship was meticulous. The air handler was carefully installed, wiring neatly secured, plenum perfectly fitted, and the condenser precisely positioned and leveled for proper clearance and vibration control. The line set was pressure-tested and vacuumed as well. They also left the work area clean and neat.

Please congratulate them for a job well done!

They went above and beyond to ensure that things were done correctly. I could tell their standards were extremely high, and I felt relieved seeing how much care they took in their installation. I’m very pleased with the result!

After dealing with several HVAC companies, Guthrie & Sons clearly stood out as the most ethical, honest, and reliable. From the very beginning, their approach felt transparent and genuinely focused on what was best for us—not on upselling or unnecessary replacements.

We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust.

Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free.

If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.

The layout of my condo made installing splits challenging, and before I met with Guthrie and Sons, three companies either told me that it couldn't be done. Vlad studied my apartment until he found a way to install with minimal openings in the walls and without a second condenser. Mallory, who works in the office, always followed through and advised me when I ran into a hiccup and needed detailed plans for the city. My HOA appreciated Guthrie and Sons' thoroughness and was so impressed with the design, that another resident who had been wanting splits for years, decided to install splits at the same time. The team that came in was knowledgeable, professional, and hard working. They finished a day ahead of time. I'm thrilled with the way everything looks and works.

I’ve been using Guthrie & Sons for over 15 years. They installed my whole AC system and maintained it all those years and never had an issue. Well it was time for an upgrade and they’ve recently installed my second system. The team 15 years ago and the team this time around were both amazing, professional and clean. I can’t recommend them enough Matt, Ben, Christian and Bryan get 10 stars. They are a bit pricier but worth the investment when you have peace of mind and almost two decades of great service and no issues.

I had an excellent experience with Guthrie & Son AC & Heater Company. Their customer service was outstanding, and they took the time to answer all my questions thoroughly. Every technician who has worked on my AC/heater installation and now the ongoing service has been knowledgeable, respectful, and always on time. I highly recommend them to anyone in need of HVAC services!
I only wish the annual service was cheaper 🙂
