Forced Hot Air Furnaces - Troubleshooting and Repair
Roger Vizi writes in plain English, and he writes with technicians in mind, but even if you're not in the trade, you'll be able to understand what's in this book. He approaches the subject in the same way a good teacher would run a class. He begins at the beginning and takes you through to the end, one step at a time. He doesn't assume you know things that you may not know. He's particularly good throughout the service and troubleshooting sections because he shares insights that can come only from someone who has a lot of experience working in the field. The text covers the components of gas, oil, and electric furnaces. It also deals with electrical circuits, humidifiers, and electronic air cleaners. There's a solid section on heat pumps as well. The drawings are simple to follow and VERY clear. The appendix offers suggested parts inventories for service trucks, questions to ask when you're troubleshooting, a tune-up checklist, and a lot more. All in all, I think that this is one book that EVERY service technician should own. It answers the questions that a technician may be reluctant to ask at work. And that's what a good technical book should do. Great stuff!
