Heating & Cooling Resources

Heating and cooling equipment is usually replaced in an emergency, in the worst weather of the year, which is the worst possible condition for making a good decision. This section covers furnaces, air conditioners, heat pumps, ductless mini splits, thermostats, and seasonal maintenance. Correct sizing affects comfort, energy use, and equipment lifespan more than brand does, and an oversized system performs worse than a right-sized one. Start with the system you have.
