Why You Should Consider Replacing Air Conditioning and Furnace Together

If you air conditioner is making loud noises, does not cool well or has other efficiency problems, it may be time to replace it. An air-conditioning unit typically has an average life span of 15 to 20 years. However, for all practical purposes, most AC units begin to lose efficiency after the 10-year mark. This is when you have to determine whether you want to spend on expensive AC maintenance and repairs, or go for the upgrade. If you have decided on replacing an AC unit, you may also consider upgrading the furnace at the same time. This is because the efficiency of the one directly affects the efficiency of the other.

Compatibility and Matching

The blower, or the fan, is a component of the furnace which is used to blow air. The blower is used in both heating and cooling your house. So when your air conditioner is functioning, the blower plays a key role in blowing the cool air through the indoors.

Now when you replace an AC unit, you probably do so over efficiency concerns. Even when you replace an AC unit that is only 10 years old, replacing it with a new unit will save around 20% to 40% in energy costs. However, the new unit must be suitably rated, such as SEER 15 at least, in order to improve cooling performance and efficiency.

If you replace the AC unit and not the blower, the AC has to rely on the old blower. A furnace typically has a life span of 15 to 25 years. When your furnace is more than 15 years old, the blower has likely passed the optimal performance mark. This means that your AC has to work in sync with a less-than-efficient furnace.

In technical terms, this is called a ‘mismatch.’ An AC unit that is more efficient and can perform very well is coupled with a blower that lacks in efficiency. As a result, even the new AC unit begins to under perform. This is one of the key reasons why you should consider replacing an AC unit and furnace at the same time.

Why Replacing an AC Unit and Furnace at the Same Time Makes Sense

Replacing both components makes a lot of sense for monetary reasons as well. When you choose to have only your furnace replaced, it is going to cost upwards of $3,000. When you do so at the same time as an AC unit replacement, the costs are significantly less. This is because replacing the AC unit already requires dismantling many components of your HVAC system.

You can use the opportunity to have the furnace replaced as well at a fraction of the standalone replacement cost. In general, the same furnace which costs above $3,000 in a standalone replacement is going to cost around $1,000 or thereabouts when done together with an AC replacement.

When Not to Have Furnace and AC Replaced Together?

While there are plenty of reasons to replace both together, sometimes it might make sense not to do so. One particular case is when your furnace is less than 10 years old. In such a case, the blower of the furnace is still likely to deliver an efficient performance. So it can be paired with a new AC unit without too much of a compromise on the AC’s efficiency.

You can then have the furnace replaced together with your next AC replacement which should ideally happen after another ten years.
