Without the evaporator coil, your AC cannot cool your house because it's here that the refrigerant absorbs latent heat from your indoor spaces. So when it malfunctions, it's crucial that you get the issue addressed so you can get back to enjoying the comfort at your residence. This article will highlight three signs indicating your evaporator coil is going bad so you know when to contact air conditioning repair services.
Warm Air Coming From the Vents
Since your air conditioner's primary role is to cool your home's indoor air, you know there's a problem when you notice warm air coming from the vents. And if the AC technician narrows down to the evaporator coil as the culprit, they'll recommend the best cause of action depending on the severity of the damage.
Most times, all that's required is to recalibrate other components that work hand-in-hand with the evaporator coil. For instance, if the evaporator coil is frozen because the air filter is clogged, cleaning the debris buildup off the filter screen should restore the component to proper function. However, if the malfunction is arising from extensive evaporator coil corrosion, your technician will likely recommend a component upgrade.
Repeated AC Cycling Without Effective Cooling
Another sign the evaporator coil could be going bad is repeated AC cycling without effective cooling. So if it's been over an hour since you turned on the AC, but your indoor environment is still hot and humid, you might want to commission a thorough unit inspection.
A plausible explanation for this is insufficient refrigerant due to evaporator coil leaks. Sometimes, the evaporator coil will sustain extensive corrosion without a homeowner's knowledge, causing most of the refrigerant to leak out. And when the fluid's quantity is insufficient, it won't effectively absorb latent heat from your indoor spaces.
As a result, your AC will keep cycling without sufficiently cooling your indoor spaces. Before topping up the refrigerant levels, the AC technician will recommend a component upgrade to prevent any more leaking.
AC Refusing to Turn on
Nothing is as frustrating as your AC refusing to turn on on a hot summer day when you need it the most. But instead of repeatedly trying to turn it on, you should ask your AC repair technician to come and check it out. In such instances, the common culprit is usually a tripped circuit breaker.
However, you shouldn't make an assumption without asking your AC technician. Because if the real issue is a cracked evaporator coil that leaked out most of the refrigerant, then you won't get to the bottom of the issue. Leaving the repair in the hands of your technician ensures the crack on the evaporator coil is spotted and the component replaced to prevent leaks in the future.
If you notice any of the telltale signs discussed above, contact an air conditioning repair service for unit inspection.
