Customer Reviews

Cassie “Cassie” Johnson

I'm so glad to have found Four Suns! They have come out to an area they don't normally within 8-12 hours every time I've had an issue. The diagnosis has been quick and correct. The job has always gotten done within 24 hours and I've not had to deal with being upsold at every opportunity like some companies. I have 2 small children so having no heat in the winter is such a fear of mine but I always know I can call in a crisis, like family. Highly recommend!

I couldn’t be more impressed with the service we received. The technician team arrived on time, diagnosed the issue quickly, and explained everything in a way that was easy to understand. Our system is running better than it has in years. From scheduling to follow-up, the entire process was smooth and professional. Highly recommend this HVAC team for anyone looking for reliable, high-quality service.
