The sales personnel and installers were professional, experienced, and knowledgeable. Our installers, Colton and Oscar, worked tirelessly in the heat to get things done, cleaned up all the debris and were pleasant to have in our home. John Sudbeck, aka “Big John”, was informative, patient and explained all options and why what we chose was the best for us. We couldn’t be more pleased. If you’re looking for a new HVAC system, you will find Hamstra one of the best.
