What Our Customers Are Saying

I had a new HVAC system installed this week. The salesman Matt and installers Alex and Mark we’re EXCELLENT.


I have used Sentry for several years and my experience has always been nothing but good work and honesty.I have tried others but they are not the same, Sentry.


We have used Sentry for our heating & air conditioning needs for 25 years. They are dependable and efficient. Some times they can have a little higher price, but the quality offsets this.
