Here at Tipping Hat Plumbing, Heating & Electric our focus is Good Old Fashioned Service. Plumbing, Heating, Cooling, Drain Cleaning and Electric service that is done right, that will last and skillfully completed by one of our hard working, courteous service specialists.

"Very expensive. $600/hr labor cost. Just got a quote today for plumbing and electrical. 2 days of electrical work quoted for $10,000. 4 days of plumbing work quoted for $20,000 Cost of materials is for all work combined is probably $1,000. Roughly that makes $600/hr. That is simply outrageous."

Behold the Difference! Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".

"After being ghosted by several AC companies we were thrilled to have Behold answer their phones, make and keep appointments, and show up for the install. Our 1970s house is blazing hot upstairs in the summer, and after considering several options we settled on a mini split. It was installed today and our bedroom is delightfully cool. Both guys on the job were professional and courteous. They kept us appraised of what they were doing and showed us how everything worked at the end of the day. They have also promised to file all applicable rebates."
