OUR REVIEWS
FROM OUR CUSTOMERS
Don’t just take our word for it. See what over 1,200+ customers have to say about working with us!
Please congratulate them for a job well done!
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.
I only wish the annual service was cheaper 🙂
Zach M. came by and installed on new one. He was extremely professional and completed the installation promptly.
This was another great experience all around and I gladly recommend Guthrie and Son's for all your HVAC needs.
From start to finish, their team was outstanding. They worked incredibly hard, treated our home with respect, and left everything spotless—truly the cleanest job site I’ve ever seen after a major project. The installation itself was seamless, and the quality of their work shows in every detail.
If you’re looking for a company that combines deep knowledge, excellent craftsmanship, and genuine care for their customers, Guthrie & Sons is it. Absolutely five stars across the board!
What really stood out was his problem-solving ability and willingness to go the extra mile to ensure everything was operating as it should. He communicated clearly throughout the process, kept us updated, and made sure we felt confident in the work being done.
It’s not often you come across someone who combines technical expertise with such a strong work ethic and positive attitude. We’re very grateful for his efforts and would highly recommend Kareen to anyone needing reliable HVAC service.
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.
