Before You Call the HVAC Man

45 home heating and cooling fixes from a retired Georgia HVAC technician, each on one page: what is wrong, what to buy and what it costs, the steps in order, and the price a tech charges for the same job. Furnace, heat pump in winter, the electric bill and thermostat, the A/C yearly checkup, and the safety and sales questions that keep a $9,000 system out of your driveway. One PDF, 71 pages, print-friendly checklists.
