Our family was out of state and had a house sitter watching our place. She called over the weekend and said the house was about 50 degrees (in February). We called KLEBS immediately because 2 years ago the same thing happened and they were immediate in response. Within one hour they came to the house, checked everything out, and got the heat back on that afternoon. We scheduled a maintenance service on our boiler system and they cleaned and replaced anything that needed it. We now have comfort knowing everything is done right!
