My July Sale Is On, All Month Long
America is turning 250 this year, and I am marking it the way I mark most things in Kingfisher: by taking care of my neighbors. Every offer below is good through July 31, 2026. Pick the one that fits your home, tell me the code when you call, and I will take it from there.
Straight from me, Dave
I am Dave Hartzell. I have been fixing heat and air in Central Oklahoma for 45 years, and I have run my own shop right here in Kingfisher for more than 15. I put this July sale together because summer is hard on a system, and a little off the top makes it easier to do the job right instead of putting it off. There is no fine-print trickery here. One offer per household, tell me the code, and I will honor it through July 31.
