What Does an Evaporator Coil Do?

May 22nd, 2021

Summertime air conditioning issues can be uncomfortable and dangerous for Texas residents and business owners. The hot season in Dallas has a four-month spread between June and September, with average temperatures over 88 degrees. Understanding how your evaporator coil contributes to cool air distribution in your home can help you better understand the need to keep your AC properly maintained.

Evaporator Coil 101

The evaporator coil is an essential component of your air conditioner that resides inside your home and is tasked with removing heat from the air as it blows. Inside the blower compartment or air handler, the evaporator coil houses chilled refrigerant that the compressor transfers into it. Your AC relies on refrigerant, a chemical blend inside your air conditioner that can transform easily between liquid and gaseous states.

As the air from the blower fan travels over the evaporator coil, the cold refrigerant removes the heat from your home’s air. The refrigerant converts to a vapor when air travels over the evaporator coil and triggers a heat exchange. The refrigerant increases in temperature while the air temperature decreases.

How Does an Evaporator Coil Impact Your AC System?

In conjunction with your AC’s condenser coil, the evaporator coil removes heat from your home. As refrigerant changes from liquid to gas and back, it absorbs and releases heat. This is how it cools down a home. The evaporator coil plays a vital role in your air conditioning system. Evaporator coil issues affect the efficiency and performance of the AC.

Common Issues with Evaporator Coils

One of the most common problems with AC units is dirty evaporator coils. Over time, these coils accumulate condensation and mold. Condensation should drain from your system but drain pan clogs can cause water to back up and overflow, leading to water damage and other issues.

Frozen evaporator coils are also a common issue. Anything that prohibits airflow to the evaporator coil, such as dirty coils, low refrigerant, and blocked air ducts, can cause it to freeze. The necessary heat exchange that occurs in your system to cool your home can’t take place if your evaporator coil is frozen. Regular HVAC maintenance rids your system of frost buildup so that your AC can function as it should.

Signs That Your Evaporator Coil Needs Servicing

Identify the signs that indicate you have an evaporator coil issue to get ahead of AC system failures. The most common signs to watch out for include:

  • Leaks around the indoor unit
  • Warm (instead of cool) air leaving the unit
  • Frequent cycling (turning off and on) of your AC unit
  • Abnormal sounds when the AC system is running

If your HVAC technician identifies that your evaporator coil is to blame for AC issues, consider having it replaced. You should also consider a replacement if your AC is older than seven years, the SEER rating is 12 or lower, or the repair cost estimate is more than half of the replacement cost.

Why Does My AC Keep Blowing Fuses & Tripping Circuits?

May 06th, 2021

When it comes to problems with your air conditioning unit, you shouldn’t ignore electrical issues. If you have an AC system that continues to blow fuses or trip circuits, the inability to receive proper cooling isn’t your biggest concern. Electrical issues can be very dangerous and should be addressed with the help of a licensed, experienced HVAC technician. When systems are prone to overloading and short-circuiting, homeowners run the risk of long-lasting damage to home appliances and the potential of an electrical fire. When you have an HVAC electrical problem, call on the experts at Frymire Home Services to quickly get to the root of the problem and perform the correct repair.

What Causes an AC to Blow a Fuse or Trip a Circuit?

Identifying why your AC is blowing a fuse or tripping a circuit should be done by a professional as there are various reasons why this could be happening. Most often, this HVAC electrical issue is caused by:

  • Low refrigerant. Low levels of refrigerant require your AC system to use more energy to cool your home. This increase in energy requirements can trip your system. 
  • Loose electrical connections. Temperature changes can cause wires to expand and then contract. These changes can loosen connections in your breaker box, leading to tripped circuits and blown fuses.
  • Fuse box, circuit, or central power issues. Electrical overloads from problems with your fuse box, circuit, or central power supply can trigger a fuse to blow or trip a circuit. You may be tempted to swap the fuse for a larger one, but this is NOT what you want to do. Reach out to a licensed HVAC technician to diagnose the electrical issue and correct it safely and appropriately.
  • Cooling system capacitor problems. Your AC’s capacitor works with the system’s condenser to manage the proper input and output of electrical currents. If the capacitor is faulty, it can lead to blown AC fuses.
  • High temperatures and dirty filters/condenser coils. Higher temperatures mean your system will have to work harder and longer to sustain your home’s target temperatures. If your system’s filter isn’t free of clogs and debris, the extra pressure required for the system to circulate air can blow a fuse or trip a circuit.

You can avoid most AC issues by staying on top of your annual AC maintenance. Get your AC tuned and ready for the heat of a Dallas summer by acting promptly when you see something amiss!
