Question DetailsAsked on 8/9/2013

How much will it cost to replace a furnace with heater and a/c combo unit? The vent ducts are already in place.

There is no existing A/C. Existing forced air gas furnace is in basement. Thinking to replace it with energy efficient heating and cooling unit.

Click on the Home > HVAC link right under your question, and you will find a number of similar questions about furnace / AC replacement issues and costs, asbestos issues on furnaces, etc.

The general consensus is ballpark about $2-10K for a furnace depending on brand name and energy efficiency (usually around $3-5K), and about $3-7K for a new AC unit feeding into a forced air furnace and existing ducting, depending on size, brand, and what ducting modifications are needed for the AC to work correctly. Generally, in the usual case, you should be looking at the $5-10K for a normal, standard energy efficiency combined installation done all at once.
