Can I use a 3.5 ton condenser with a 4 ton air handler?

Keep in mind when pairing a condenser and air handler, it’s okay for the air handler to be a bigger size than the condenser, but never the other way around. It is also always good to check equipment compatibility with the manufacturer and AHRI as well. In fact, we recommend you do that.

How many square feet does a 3.5 ton AC cool?

Choose a unit that is 3.5 tons if your home measures more than 1,800 but not more than 2,100 square feet. A four-ton unit is suitable for homes that are more than 2,100 square feet up to 2,400 SF.

How many sq ft will a 4 ton AC unit cool?

Step 5: Match your square footage to an HVAC size chart

Home Sq Footage Air Conditioner Size (tons)
600 – 1,000 square feet 1.5 tons
1,000 – 1,500 square feet 2 tons
1,500 – 2,000 square feet 3 tons
2,000 – 2,500 square feet 4 tons

How much does a 3.5 ton air handler cost?

Air handlers run from $500 to $3,500. A 3-ton output is standard for homes 1,500 to 2,100 square feet. 3-ton units run $700 to $1,500.
Air Handler Prices.

Tons BTUs Range
3 36,000 $700 – $1,500
3.5 42,000 $900 – $1,600
4 48,000 $1,000 – $2,000
5 60,000 $1,200 – $2,200

Does an air handler and condenser have to match?

The coils, blowers, wiring, etc. need to be compatible in order for an air conditioning system to operate efficiently and keep your home comfortable. If you combine a condensing unit with an air handler (or furnace) it wasn’t designed to work with, in the best case the result will be reduced operating efficiency.

Can you mix match condenser and evaporator?

When your evaporator and condenser coils are mismatched in size, the smaller sized coils won’t be able to keep up with the capacity of the larger sized coils, which forces the entire system to run longer. And the longer your system runs, the more energy it eats up.

What size central air conditioner do I need for a 3000 sq ft home?


Since larger homes are costlier to cool, you’ll need a 5-ton unit to cool a 3,000 square-foot home.

What happens if my AC unit is undersized?

If your AC is too small for the size of your home, it’ll keep working to reach that temperature, but to no avail because it lacks the capacity to cool such a large space. As a result, it never completes a cycle and runs continuously.

What size AC do I need for a 2000 square foot house?

If your home is 2000 square feet, you can calculate your HVAC needs the same as you would for a 1600 square foot home. Assuming one ton of cooling capacity can cool 400 square feet of your home, you’ll need about 5.0 tons of air conditioning capacity. Multiply this by 12,000 BTUs, and you’ll get 60,000 BTUs.

How long do air handlers last?

In general, most HVAC systems will last from 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable.

What is the typical cost to install an air handler?

But much like a furnace, repairing or replacing an air handler can be expensive if you’re unprepared. According to national estimates, an average new air handler costs between $700 and $5,600.

Is it cheaper to replace furnace and AC together?

On its own, a replacement air conditioner can cost between $4,350 – $12,095. A lone replacement furnace can cost between $3,000 – $7,600. (Both of these ranges include the cost of the equipment, labor and other fees.) But you can save on labor expenses and fees when you replace both systems.

Can I use a 5 ton condenser on a 3 ton coil?

The short answer is, you can’t. A good tech might be able to get it to work with like a TXV, but you are going to be bottle-necked at the 3-ton. There is no way you will get 5-ton capacity after that. It will mess up your warranty and your efficiency will be off.

How do I know what size air handler I need?

6 Steps to Properly Size Your HVAC Unit

  1. Step 1: Calculate the square footage of the area to be cooled. …
  2. Step 2: Next, multiply the square footage obtained for each area by 25.
  3. Step 3: Then, add 400 for each person who works in that particular area.
  4. Step 4: Finally, for each window, add 1,000.

Can you use a 2.5 ton condenser with a 2 ton air handler?

In spite of the nay sayers here yes you can and it can work very well. You will indeed have to install an expansion valve that matches the condenser capacity. It also depends on the type of evaporator coil and furnace or Air Handler that you have.

Can your AC unit be too big?

Too Hot or Too Cold Air
An oversized HVAC unit can make your home’s inside temperature uncomfortable. An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. First, your home won’t benefit from gradual, even heating and cooling.

How much more efficient is a 18 SEER vs 16 SEER?

Having a higher SEER rating will save you money on energy efficiency. An 18 SEER is around 12.5% more efficient than a 16 SEER. That means for every $100 you spend to cool your home with a 18 SEER, you’ll save about $12.50 more than the 16 SEER.

Can you Oversize an evaporator coil?

The added surface area slows airflow and you get better heat and dehumidification.”, while the answer to “Can you Oversize an evaporator coil?” says the exact opposite: “After extensive research, we have found that having a matched or oversized evaporator coil will not control humidity enough.

What happens if condenser is oversized?

Since an oversized AC is too powerful for your home, it will quickly cool your home then shut off, which can raise your energy bills and wear out your AC (from all the starts and stops).

Why condenser is bigger than evaporator?

Condensers have to be larger than evaporators in terms of their heat exchange capacity because they are not only rejecting the heat absorbed by the evaporator… they also need to reject additional heat that the refrigerant gains in the compressor from the heat of compression.
