Furnace Cost

How much does a furnace cost?

The idea of fitting a furnace in a home is not a new one, but modern technology means that we now have more efficient models available that can heat homes at little cost. Whether you use a duct free furnace in a smaller home or a duct system that will help to heat larger properties there is much to recommend a furnace, but bear in mind the cost will vary according to the type, size and power of the system.

General Cost

• A simple gas wall furnace, designed to heat the space around it, will cost between $500 and $1500 depending on the type you choose. One fitted on the floor will cost a similar amount, and in both cases installation can be anywhere from $1000 to $2000.
• If you want to replace your old furnace with a more efficient version you can look to pay anywhere between $2000 and $10000 depending on the complexity and efficiency of the system you choose to have installed.
• For an oil furnace you may be looking at a cost of around $2000 to $10000 for the various types, and more if the job is particularly complex.
• The cost will vary according to the local labour rates in your area.

Extra Cost

• You will need a fire inspection in most cases by law, and can expect to pay at the most $75 for this to be carried out.
• If you replace an older furnace you may need to have chimneys relined, an expensive process that can cost anywhere between $500 to $2000.
• If you want an air cleaner added – and it is often a worthwhile investment – allow an extra $500 at least.


• Beware the presence of asbestos in ducts that have been in use for some time – this can be expensive and costly to remove, and dangerous if not removed.
• Make sure any quote you get includes the removal of the old system and everything that is included in the job – especially where chimney linings are concerned.
• Check with your local authority for possible discounts available for installing efficient systems – these can be found nationwide.


• Get a number of like for like estimates and check them against each other for price and content.
• Use local listings and internet cost comparisons for names.
• Ask around – you may find a friend or family member can recommend a good fitting service, and discounts are sometimes given for referrals.
