Does the evaporator coil affect the furnace?
In most cases, the evaporator coil will work with both your air conditioner and your furnace, depending on which system you are using at any given time. When your evaporator coil is functioning as part of a cooling system, its job is to remove heat from the air inside your home.
Can you oversize your evaporator coil?
You cannot oversize your evaporator coil because the AC won’t function properly and might get broken. The coils should be of the same size as the other to avoid the rise of complicated problems.
Are evaporator coils interchangeable?
Most manufacturers specify that if you replace either the evaporator coil or condenser coil, it must be the same size (and SEER rating). Otherwise, they’ll void any remaining time on the warranty. This is because manufacturers specifically design both coils to work synergistically.
Can you just replace the evaporator coil?
These coils are both housed within the same AC unit but are still separate components that must work closely together to cool your home. That said, replacing just one of these coils could cause major problems for your unit. Let’s take a closer look at when replacing the entire unit is more cost-effective.
How much should it cost to replace evaporator coil?
between $600 and $2,000
An AC evaporator coil replacement costs $1,000 on average, with a typical range between $600 and $2,000. About 40% of the price—about $400 to $1,000—goes towards labor costs. Warranties range from five to 12 years and cover the price of materials.
What is the difference between condenser coil and evaporator coil?
Evaporator Coils vs. Condenser Coils. The evaporator coil is the part of an air-conditioning system that removes heat and moisture from indoor air to cool it. The condenser coil takes that heat and releases it outside.
Is it bad if my evaporator coils and condenser coils don’t match?
Problems Arising From Mismatched Coils
When an evaporator and condenser coil are not matched right, the smaller sized coil is unable to keep up with the larger sized coil’s capacity. This forces the entire unit to run longer.
How do I know what size evaporator coil I need?
If the evaporator must move 400 gallons per minute: 14 x 400 = 5,600. Multiply the answer by 500: 5,600 x 500 = 2,800,000. This answer is the evaporator’s size, measured in BTUs per hour. Divide the answer by 12,000: 2,800,000 / 12,000 = 233.33.
Should evaporator coil be larger than condenser?
If anything, you want your evaporator a half ton to a full ton larger than your condenser, not the other way around. The added surface area of the evaporator coil will increase the efficiency of your system.
Can I use a 2.5 ton coil with a 3 ton condenser?
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.
Do evaporator coils have SEER ratings?
Coils by themselves don’t have a SEER rating. The SEER rating is determined by the combination of a condenser, coil, and air handler or furnace. The efficiency of the three pieces of equipment are rated as a system. If you change on of the components, it is likely the SEER rating will change.
What happens if your condenser is too big?
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).
What happens if my furnace is too big?
Oversized Furnace
The problem with a furnace that’s too large is that it puts out too much heat for the space, which causes the thermostat to shut the system down early. This places extreme stress on the furnace, which will eventually cause the system to break down.
How do I know if my furnace is oversized?
Indications your furnace is excessively large include it being overly noisy, unrealistic efficiency ratings, and temperature imbalances throughout the home. Furthermore, you will notice higher operating costs, short cycling, installation challenges, and humidity issues.
How many BTUs do I need for a 1300 square foot house?
The 1,300-Square-Foot Answer
When looking for the quick answer to how much air-conditioning power you’ll need to adequately cool a 1,300-square-foot space, the answer is 23,000 BTUs per hour of air conditioning power. This is the base capacity needed for a 1,200- to 1,400-square-foot house.
What size furnace is needed for a 1500 square foot house?
between 45,000 to 90,000 BTUs
A 1,500-square-foot home will require between 45,000 to 90,000 BTUs. A 1,800-square-foot home will require between 55,000 to 110,000 BTUs. A 2,100-square-foot home will require between 65,000 to 125,000 BTUs.
How long should it take to heat a house 10 degrees?
On average, once you turn on your furnace, it should take about an hour to increase indoor temperature by 1 degree. Afterwards, it’s 45 minutes per degree.
