I love this company! I started using them about 15 years ago when the father answered the phone, one son came to the house to do maintenance and another son knew everything about upgrading your HVAC if needed. Cousins and uncles also joined the company. Now it is bigger and better with non family employees who are all stellar. The guys wear booties in your house. They come when they are supposed to. They are respectful to your needs and they are competent beyond belief! While I still love sons Ben and Matt, I also love Wayne who is a fabulous technician who always shows up with a smile. After their most recent job, which was not easy, Wayne called to say he made an error and overcharged us by a few dollars. Who does that these days? We have a rental where Guthrie and Sons also maintains the HVAC and the tenant goes out of his way to tell me how wonderful Guthrie is and how he appreciates that I find fabulous service providers. I have high standards, and if you do too, then don’t hesitate to call Guthrie and Sons!

I had floor tile installed recently. Either the drainage line was damaged then or prior and I did not notice. I had a general understanding of how it should work but was not 100 percent sure. I called Guthrie because they installed the unit. The customer service on the call was very friendly and knowledgeable and a tech came out the next day. He fixed the problem very quickly and was very helpful. I was charged a very reasonable fee for the service time. Well worth being sure it was done right. This was a great example of a local business that does a little extra to be friendly and get returning business. I will definitely use them again and recommend their services.

I wouldn't let any other HVAC company into our home. These guys are experienced professionals, responsive, kind, and very pleasant. They are even able to perform miracles! The attic space in our 100 year old home is no higher than 12 inches. Nine other HVAC companies refused to install ducting for us. The Guthries made it happen. That was nearly 10 years ago and everything is running great. The Guthries are absolutely the best in San Diego.

We got a few quotes from companies that were telling us we needed 10-20 thousand dollars worth of work without great explanations as to why. We’re so glad we called Guthrie & sons. Vlad came out, took the time to explain to us what was happening and offering multiple solutions. It was apparent that he wasn’t a salesman but knew his stuff and took this role as a consultation. He gave us multiple options including a repair that ended up working for less than a thousand. On top of that we asked him how much Guthrie would charge to compare agains the other big HVAC companies in San Diego and they beat the price hands down. Don’t go just for the price but their honesty. I feel every other company came out to squeeze as many dollars out of us as they could but not Guthrie & sons and Vlad. Highly recommend

Wayne G. was our technician. He took out our 67-yr-old (!!!!) furnace and put in a new one along with a new thermostat. While in our home, he was very friendly, conscientious, and respectful. Every-thing was cleaned up perfectly after the completion of the work.Wayne explained all parts of the process ahead of time and then documented each step of his work with photos, which are copied to us. Very thorough paperwork and instructions were left for our reference.My husband had obtained several estimates and chose Guthrie & Sons as the best contractor for our job.⭐️⭐️⭐️⭐️⭐️

Guthrie and sons came highly recommended and we are extremely happy we went with them after having multiple quotes for mini splits A/C in our home. Vlad went above and beyond to make sure we had the exact system we needed and also that everything was done perfectly. We have a 1950's home with no insulation and original windows and the system kept our home cool and comfortable on the hottest days and also warm and cozy on the coldest days. We are also extremely happy with how quiet the system is. The outside unit is next to the office window and the unit is whisper quiet. We also love the fan setting on the units on those San Diego days that you just need to move the air in the house without closing everything up. Can't say enough good things about Guthrie and sons and Vlad's high level of expertise!

We recently had Guthrie replace our 1960s gas furnace with a Bosch mini split system. Kareen and his crew were fantastic. We’ve worked with quite a few contractors and this experience was easily the most positive.The team was communicative, talking us through what the process would look like at each step. They listened to what mattered to us visually and practically, and when they discovered obstacles due to the construction of our home, Kareen gave clear explanations of our options. He gave us recommendations that reflected our preferences such that I could tell he had heard us before.Kareen and team stayed past 8 pm on the night they had said the job would be complete. I was impressed by their dedication to being on time. Even working late, and with our overly enthusiastic puppy barking her head off, the crew was positive and calm.I would work with these guys again 100 percent.

All the technicians have been very professional. The receptionist has also been amazing. There was a small mix up on both their end and mine and they went above and beyond to fix it, honor their commitment to the customer and ensure customer satisfaction. Given my role in that mix up, I was shocked and extremely pleased they were willing to honor their commitment to me. Highly recommend the company. As a side note my (not so new anymore) HVAC system has worked beautifully and the new duct they put in has completely transformed the comfort in my bedroom. It's no longer the hottest room in the house. The whole house is comfortable! Thanks.

Guthrie & Sons A/C Service came highly recommended, and I can see why.

We used Guthrie for our heater installation 9 years ago, and referred them to a family member as well. We just now decided to get Air Conditioning installed and our first call was to them because our prior experience was so positive. Our salesman Zac spent a lot of time answering our questions (we had a lot) and we never felt pressured. After we made the decision to go forward, we were able to get it installed right away. The crew of 3; Alerik, Cristian, and Jair were professional, knowledgeable, and very pleasant gentleman to be around. They kept us informed and made recommendations all along the way. When they noticed some things we had that were aged or not functioning as they should, they fixed it all up without extra charge so that the installation would go smoothly. If you want superior quality of work and equipment, and professional installation, Guthrie and Sons should be your first choice. Very satisfied.

We are very happy with the service we get from Guthrie & Sons. They installed our HVAC summer of 2016. They've been visiting us every year to ensure that our AC is operating efficiently and solidly.

The part came in and Zach returned and repaired the heater quickly and efficiently. He was very friendly. He asked how our son was and how school was going. Just an all around great guy. We would call again with any need we had. We are very satisfied not only with the repair but the great customer service.

Very professional from the first call to the service. Juan was great! He called 20 minutes prior, as promised, and came out to check why my furnace wouldn't turn on. It turned out to be a really minor issue, but he took time to check everything, make some minor adjustments, and test everything to be sure there wasn't something else going on. Answered all my questions thoroughly and offered helpful advice. I'm happy to have found a company I can trust, and know who to call next time I need service.

There are at least 5 areas why I rate Guthrie and Sons 5 out of 5 stars:#1 - A great front line.Amy and Courtney were always attentive, found someone to answer my questions, and excelled in coordinating visits to our house.#2 - Very knowledgeable staffZack provided all kinds of information that included budget concerns, energy use and quality. He thoroughly went step by step over the project inclusions and the cost.#3 - Direct involvement by the owners.Matt, one of the Guthrie owners, came with Zack to evaluate placement of equipment, duct work and other requirements.Photographs were taken so the project could be further reviewed before a crew was assigned.#4 - Hard working, polite and responsive crew.First on the scene were Cristian, Aleric and Levi.When more crew was needed, Jay and Carson came to join them.Stunningly, they ALL stayed until all my questions were answered and I felt comfortable using the newly installed HVAC.#5 Outstanding follow upMichael was excellent in arranging for completion details.Rob was awesome in completing everything that needed to be done.Guthrie and Sons is definitely 5 stars out of 5 stars.

In just two days I got a new Mini Split Air Conditioner/Heater System! From the beginning until the spotless ending I had such impeccable service from Guthrie & Sons. Alerik K., Christian, and Jair M. We’re the picture of efficiency. They arrived the minute they said that they would. They bent over backwards to make sure that my experience with my installation was perfect. These men were polite, patient, and efficient.What impressed me most was their willingness to go beyond what was simply required of them. No issue was skipped with their attention to detail. How refreshing to deal with efficient knowledgeable young men. All I can say is, THANK YOU. In an unbelievably short time I went from hot to complete comfort. I wholeheartedly recommend this company and these young gentlemen.

Kareem called before arriving and showed up on time. He reviewed the job site and the task to be done. When Mike, the other installer arrived, they coordinated their work the get the job done. Another fellow arrived later to run electrical lines in the attic. When unexpected issue arose, Mike brought it to my attention and with a sheet of plywood and a 2x4 that I had on hand, they were able to make a superb repair. These guys worked 10 hours on a very hot day except for a lunch break. At the end of the day, Kareem reviewed my system’s features with me. He even took time to answer a few of my 6-year old’s questions about what they were doing.I have worked construction and the effort and professionalism these guys put forward was exemplary. These days it is refreshing to learn of and observe such professionalism. They represented Guthrie & Sons very well. I am pleased that I choose them for my A/C installation. Now if only I could find a plumber and an electrician who are as adept in their field.

The highly professional and affable team that installed our Bosch multi zone ductless HVAC system did so on time and within budget. They demonstrated skill and ingenuity in managing the inevitable problems encountered in installing three heat pump units outside and 6 air handling units in ceilings and under the floors of our 116 year old house. They exude an aura of confidence and flexibility, and are backed by a company that makes good on its promises.

Update for today's visit: Glad to see Zach M. back! He's been servicing our HVAC for years.Our interactions with everyone at Guthrie have always been great. They are respectful towards us and our property. We are a repeat customer and will recommend them to our friends and families. Zach is our regular person. He's friendly, courteous, and very easy to talk to. He never hesitated to help and provide assistance with issues not related to our HVAC but more on our plumbing in the past.

Great, professional people. Everyone I spoke with was very polite and easy to deal with. Very knowledgeable of every aspect of what we needed. I would recommend Guthrie & Son's Heating, Air & Energy to anyone. They are top-notch.

It’s so easy to have Guthrie & Sons be our HVAC company. I love it! They do what they say they’re going to do. The people who work on your unit show up on time and are clean and respectful. There’s no reason I would look anywhere else for service.

Excellent Customer Service and Quality Installation. I have been using G&S to service our HVAC systems for five years now and have been thoroughly impressed. Their customer service is incredible - I cannot recommend them highly enough. Today, Sam serviced our furnace and was incredible in his kindness, patience, attentiveness, and thoroughness.

Guthrie & Sons, which we found on the BBB site, has been taking care of the furnace in our attic for several years, and we have always been satisfied with their service, which is thorough and reasonable in price. Dave came for the first time today. Like the other Guthrie representatives, he remained pleasant and helpful, even during the struggle with our "10-ton-truck" sort of piano that has to be moved to change the filter and which always resists being put back in place by threatening to topple over.We were happy to learn, too, that Guthrie is willing to service our mini-split AC, when the need inevitably arises in a few more years, even though a different company installed it.

So sorry for the delay! I am pleased to send a review for his great service! The maintenance performed was quick and thorough. Zach is the nicest guy to have for home services, as with all your crew! When work needs to be done, I look forward to his visit because I can rely on the best. He is reflective of what I know Guthrie & Sons represents....exceptional HVAC service. Applauds to Zack and all. Give him a nice raise! Many many thanks...Cat Swain

When looking for a company to install heating & air, a neighbor recommended Guthrie & Sons. Right from the start I was impressed with the scheduling coordinator who was friendly and very knowledgeable. Steven was honest, offered the right solutions and made the process clear and understandable. When the install team came, they were ultra careful with our home and they did a great job. When there was an issue with our slate roof that precluded them walking on the tiles; the owner of the company came by to find a solution! So impressive and really shows the degree of customer care they provide. We are very happy with the service, the products offered, the quality of the team and the fair pricing.

I am very happy with Guthrie & Sons. They gave me a fair price and were able to install my new furnace 2 days after I called them. The installers were pleasant and easy to work with. They finished in a timely manner and left the house spotless.

During the peak of the summer and in the middle of a San Diego heat wave, they were able to set an appointment at 1-week when nobody else in San Diego could do less than 3 weeks.Zach showed up exactly on time and was obviously an expert with a wealth of knowledge and experience. He was able to get my air conditioning cooling like a champ again within an hour. He presented me with 3 options, but actually recommended the least-expensive option and advised me on some services that I would likely need in the future.I couldn't be happier, and if I ever have trouble I will call them again!!
