I highly recommend Happle Well Drilling. I used Happle Well drilling in November 2014. This company was very knowledgeable in every aspect of this field of work; not only in well drilling but in the Geo thermal systems at every level they work hand in hand with some of the very pioneers of the Geo Thermal industry and their knowledge , expertise, work , and attention to detail are impressive to say the least. they produce quality work from beginning to the end and follow through with the home owner to ensure they are satisfied and informed. this is the most efficient and cost effect system; it is amazing. Let happle drilling cut your energy costs in half year round, by installing and ensuring the best most efficient up to date geo thermal system for your home today . we did and by this time next year what we saved will have paid for this new Geo thermal system! Professional expertise and personal service Happle well drilling is outstanding. Thanks Jason Happle. Satisfied Home Owner
