Customer Testimonials
Dave was fantastic! He was very polite and professional and explained everything that he was doing and the condition of all my units. He did a very thorough job servicing everything!
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.
Thanks to Juan for his punctual, courteous, friendly, and efficient service. Just what we appreciate about the whole Guthrie team. Highly recommend!
Alerik and Jair were very professional. Before they started the installation, they explained what were included on the service and what will be the outcome of the installation. They are both knowledgeable and courteous. If they need permission to do something, they call us. I will definitely refer them to my friends and family as they did outstanding work.
All aspects of the project were easy and went smoothly. I appreciated how quick they got back to me and scheduled the estimate and install. Pricing was very fair and installation crew did a great job and was respectful of my home and explained everything when it was alldone. So very happy I did this. I would highly recommend Guthrie and Sons.
Guthrie & Sons from their sales people to their office personnel to their repair team are great! I’d like to give a shout out to Dave, who came out for a simple repair but handled it very professionally and a shout out to Amy and Courtney for handling my calls. Thanks guys!
Very happy with heat pump installation. The crew was professional, knowledgeable, arrived on time, and left our house clean after work was done. Kareem patiently and thoroughly answered all our questions, even after a long work day.Guthrie & Sons was very easy and efficient to work with, would recommend them to anyone. Price was reasonable, slightly under our other three quotes. Vlad, who came to give us initial quote, sold us with his knowledge, patience and professionalism.
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. Their crew came early as requested, were professional and trustworthy, completed installation of a new Gree ductless A/C unit without a problem, and made the whole experience very satisfying. The unit works really well and is definitely worth it now.
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.
Zach is terrific. Always does what he promises, friendly, efficient , and honest. And not overwhelmed by 3 dogs “helping” him. Have used this company for four years with two houses. Wouldn’t call anyone else!
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 team members who visit are very friendly, courteous, professional, prompt and clean. Juan visited today and did a fantastic job. The office team is just as helpful. We highly recommend Guthrie & Sons for all your HVAC needs.
New heat and air conditioning installation. We chose a Bosch heat exchange system. Looking forward to lowering electric expense. Installing went smoothly. Karen and Rob are very professional and knowledgeable about the products and the ins and outs of installation. Guthrie and Sons true professionalism showed throughout the sales and installation process.
Zach was great. He came last week quickly diagnosed the problem. He gave us a couple of possible scenarios for repair time. 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.
Kareem’s first visit to install heating system and thermostat was good, but he left the gas air loose that our whole house smelled like gas. He needs to be careful that the gas pipe is completely sealed. It would of cause explosion in our house if we didn’t ask for immediate repair. Please be careful on sealing gas pipe.
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.
Mikey and Crew were great. They were very respectful of our house and were on time. The first time they came out, they completed the job as promised and worked above and beyond to get it done. The second time they came, again they were on time and completed the job within the quoted time. The guys were great and we will call again and suggest others to use them.
Mike and Jair of Guthrie & Sons were very knowledgable and thorough with their work when installing our replacement A/C unit. They didn't cut corners and ensured the installation was smooth and checked out with quality workmanship. I definitely recommend these guys for your A/C needs
Fantastic service. I loved how Vlad, the technician, explained everything when he was going about the work so I could understand what the issue was. He was very polite and fixed the issue quickly and at a very affordable price.
The on site team was amazing! They showed up on time, didn't have music blaring & were super cool to my dog too. They kept me posted as work was being done & had a 3 zone mini split installed in just 2 full days
We were very happy with Vlad who diagnosed our issues and followed up with us. And, Mike and Jair did a wonderful job installing our new mini split system. All of them were courteous, on time, and professional! I was also very impressed with their attention to cleanliness. They were meticulous in putting shoe covers on/off and even laid down drop cloths where they would be moving items.Thank you for a job well done!
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.
Dave was very professional and did a thorough job assessing our AC unit. Even though it was on its last legs, he attempted a fix to see if that would rectify the problem. He spent his time and answered our questions regarding replacing the system.
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.
Kareem and his team was amazing! Kareem communicated all the details and answers any concerns I had. I recommend Guthrie & Sons for HVAC services as they were very professional.
We started hearing an odd sound come from our system's pump. We called Guthrie and Sons in the evening and they scheduled someone to come out the next day. They arrived earlier than the quoted time frame and were able to easily diagnose the problem. They made the repair right away. Thank you for the good, efficient service.
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.
Very professional service here. I had a system installed and it was like an army of people came over to do the work. These employees liked what they did for work, and actually like the co-workers they worked with. The company is doing something right because they went out of their way to make sure the customer (me) was satisfied. Happy employees means happy customers.
On time, quickly identified issues with AC unit and repaired. Have used in the past for heater and thermostat issues. Similar food experience. Will definitely use them again.
Wayne came and installed our new Rheem furnace and electronic air cleaner today. Came on time and very professional!The installation went very well. He answered all our questions about the new unit. We are very satisfied with this company. Thank you Wayne. You are the best!
Our interactions with everyone at Guthrie have always been professional. 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 amongar the staff. 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.
Dave did our scheduled AC tune-up this morning. He checking and tested the furnace, s the AC unit outside and T-stat and gave us a good update. Everything was fine, he answered all me questions and was a very pleasant and professional technician.I appreciate Guthrie’s attention to detail and their customer service. They will always have my business and strongest recommendation.Jody Robbins
Dave J was great and very thorough. On time, informative and he described every step of his actions in detail. He was a pleasure and he and Guthrie & Sons are highly recommended!
I tried to respond to a phone message regarding Zack but was unable to send my response. This review is for Sam and Zack. You have responsible well trained technicians at Guthries. I always receive the best service and advice from your crew. I recommend you to friends for any and all Heating and AC needs!.Thank you.Elaine May
Well, this was going great til we got to the thermostat… I had two furnaces installed and I was told one of them needed a new thermostat. I reply to the installers “I will deal with it“, meaning I would have to deal with the extra money but go ahead and install. Well, it wasn’t taken that way and they did not do the insulation. So, my installlation for a single thermostat to get installed suddenly came to over $300. Like I said, everything went great until we got to this part.
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.
Dave, our technician, was on time, performed the service efficiently, kept us informed and cleaned up when he was done. He was also friendly but professional. All good.
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.
David was very professional prompt and courteous. He was able to troubleshoot the issue very quickly and was able to get my heat pump system started up in no time. I highly recommend this company and have always found their staff awesome and reliable through the years.
Outstanding service, on time and quickly got our furnace running again. Technician was knowledgeable and friendly. Thanks Guthrie and Sons for a job well done.
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
Excellent service. Always professional. I have used this company for over a decade and have never been disappointed.
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.
I spend over $10,000 with this company for my home Heating and A/C unit. They provided a written warranty of 10 year for parts and 1 year for labor, contract good until August 2022. My A/C until quit working last week (September 13, 2021) called and scheduled a diagnostic for a week later. When they showed up they informed us the cost for the repair would be over $800 for a bad Capacitor that cost $14.95 at Amazon and that our A/C unit was out of warranty due to that it wasn’t previously serviced. I asked them for a copy in the contract where it clearly lists that the A/C needs to be serviced regularly which they could not provide. We kept all original purchase receipts and paperwork from the first day we hired them for the service, looked and searched for any written instructions on how to keep up with A/C system and found none. We are very upset Guthrie and Sons Heating and A/C clearly aren’t the right company to do business with. We feel our system was never in any way protected as Guthrie and Sons heating and A/C failed to honor any written warranty. I hope anyone searching for a A/C company reads my story and hope our situation help you determine your decision to use them. I’m not a happy customer and would never recommend them for any service.BTW I am a certified mechanic and work on automotive A/C units. They are no instructions to routinely service to A/C or heating systems on any vehicles, because they’re just isn’t. Home A/C units are built very similar to automotive they do mot require any service unless they fail or Freon leaks out. Just like your fridge or A/C wall unit. They could not provide of the routine services for home A/C unit required because there just isn't any. They are a bunch of crooks and would not recommend anyone use them.I’ll provide a photo copy of the contract
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!!
