In Knots and Coils: Fixing Your Evaporator Coil

The loss of your air conditioning is probably the last thing you need in the midst of the relentless July heat.

And when you start to notice high energy bills in tandem with longer cooling times while lazing around the house, it’s easy to break a sweat in figuring out where, exactly, to point your finger. If this sounds a little too familiar, we’d like to take this opportunity to introduce you to a key element on your home’s cooling system: your evaporator coil.

A single piece of your overall HVAC unit, you may think to fix a damaged or inefficient evaporator coil would be a quick fix… but that isn’t always the case.

What is an evaporator coil?

The evaporator coil is the coil of your HVAC unit that aids in cooling and dehumidifying your home.

It is one of the most important components of your system, as it plays a major role in regulating your home’s temperature year-round.

How do I know if something is wrong with the evaporator coil?

If your home is becoming more hot and humid despite constantly turning down the temperature on your thermostat, your evaporator coil might be in need of attention.

For one, it may be an issue of cleaning. When the coil collects dirt and debris, it won’t be able to absorb any moisture from the air around it, rendering it essentially ineffective.

Leaks of the coil may also occur, however, when the joints are otherwise not connected well or if portions of the coil are corroded and weak. A leaky evaporator coil will lead to a loss of refrigerant in your overall HVAC system, and thus a warmer indoor temperature.

Okay, what do I do from here?

If the evaporator coil is in need of a cleaning or routine maintenance, a simple replacement may be all that’s in order.

But in some cases, replacing your entire unit may actually be more cost-effective. You should opt to replace the entire unit instead of a single coil if:

● Your A/C unit is more than 8 years old
● Your evaporator coil is an obsolete model
● Your evaporator coil relies on R-22 refrigerant (as the industry standard is currently being transitioned to the R-410A refrigerant)
