Thank you so much for assigning a positive, knowledgeable, and efficient technician for our furnace time-up! he represents everything we love and have grown to expect from holt! Now serving the defiance, ottawa, and paulding oh areas. Find great tips on how to winterize your cabin, maintain your plumbing, and many other great tips! Will involve a bit more work, including possibly a new flue and changes to the pipework, so this will probably cost.
