Should evaporator coil be larger than condenser?
If your condenser and evaporator coils don’t match in size, it could lead to higher temperatures and humidity levels in the home. On the other hand, an evaporator coil that’s larger than the condenser coils will cool the home well but will remove little to no moisture from the air.
Can I use a 3.5 ton condenser with 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.
Can you mix and match HVAC units?
Different brand equipment can almost always work fine. However, because manufacturers design their components to work optimally together, the potential exists for some loss in efficiency when mixing and matching. Keep in mind, you are also combining systems that are different ages as well.
Does an air handler and condenser have to match?
The short answer is that a handler and condenser can be different brands and the unit will function properly. Ideally, it is better to match the same brand of condenser and handler if possible, and have them both replaced together.
Can a 2 ton outdoor unit be installed with a 1.5 ton indoor unit?
A straightforward answer for your question would be YES.
Do evaporator coils have SEER ratings?
The federal government requires that you have an air conditioner unit with a seasonal energy efficiency ratio (SEER) rating of at least 14. A SEER is an energy efficient ratio for all HVAC units. This is because you can’t match an evaporator coil with a SEER 14 rating with a unit that has a rating of 13 or lower.
Can I put a 5 ton compressor in a 4 ton unit?
A 5 ton outdoor unit will not work with a 4 ton indoor coil and air handler or furnace.
Can you put a 2 ton condenser on a 3 ton coil?
a 2 ton condenser with a 3 ton coil), the orifice needs to be changed to match the size condenser you are installing. In this example the match would require changing the 3 ton orifice that comes in the coil to a 2 ton orifice.
Can you put a 5 ton condenser on a 4 ton coil?
You do see 4 ton coils as an AHRI match on a 5 ton condenser. Usually though this is not the best match. Customer should get better dehumidification only if sized correctly.
Can you mix and match air handler and condenser?
These are called “matched systems”. 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. In the worst case, the mismatched system may not work at all.
Can you undersize an evaporator coil?
So the next time you’re tempted to replace one coil and not the other, or you want to undersize or oversize one coil, the consensus is: don’t do it.
Can I replace just the AC condenser?
A common question we get is if you can replace just the condenser. The short answer is yes, you can. Some technicians often do in some cases. When you replace the condenser unit along, you’ll have old components mixed with the new.
Should I replace condenser with compressor?
As you can see, condenser problems and compressor failures are often related. Thus, it might be a good idea to replace a condenser when your compressor fails. This debris comes from the failed compressor, and it’s almost impossible to remove this debris completely from the condenser.
Should I replace evaporator coil only?
Often replacing the AC is much more cost-effective for several reasons. Replacing only one coil can cause significant issues with your AC. Just replacing the evaporator coil can make it an incompatible match with the condenser coil. You should also replace the whole AC unit if your old one uses R-22.
Can you use a 3 ton air handler with a 2.5 ton condenser?
That’s always a good step because you are increasing the chances of your HVAC equipment being compatible. So, if the evaporator coil in the 3.5 ton air handler has a thermal expansion valve (TXV) for metering, it will probably work. You would need to check that, but as long as it does, you’re probably good to go.
How far can a mini split be from the condenser?
The standard length of mini split lines is 25 feet. Why is that? That’s the anticipated distance between the outdoor condenser and the nearest indoor air-handling unit. In some cases, the space from one unit to another may be slightly shorter at 15 feet, so you’d need a line that’s about as long.
How far can the condenser be from the evaporator?
A rule of thumb is to maintain at least two-feet (24″) between the A./C compressor/condenser unit and any nearby obstruction such as a building wall, shrub, or fence.
How much clearance does a condenser need?
How Much Space Do You Need Around an AC Condenser? Horizontally, the minimum clearance space for an air conditioning condenser is one foot, however, two to three feet is optimal. Vertically, the minimum space for an AC unit clearance from trees above is five feet.
