In an AC unit, evaporator coils allow for cool air to be generated and distributed throughout your home. The coils are made of copper, steel, or aluminum and connect the condenser and the expansion valve. As the refrigerant passes through these coils, it is boiled and turns into a gas. It then goes into the compressor, and then the cycle begins again. Without the evaporator coil, heat won’t be absorbed from the air in your room, and the low-pressure refrigerant cannot pass through the condenser.
If you believe your evaporator coil needs an inspection, repair, or replacement, schedule an appointment by calling (817) 631-2507.
Signs Your Evaporator Coil Is Going Bad
Fixing or replacing an evaporator coil is a major repair job. The longer you wait, the more strain it can put on your air conditioning system, and the more you’ll spend on restoring it.
Fortunately, the signs of an evaporator coil problem are obvious, and include:
- Leaking Refrigerant: If refrigerant is leaking, the coil must be sealed, or else refrigerant will continue to be wasted. A lack of refrigerant will cause your air conditioner to malfunction and not deliver comfortable air.
- Frozen Coils: A buildup of ice on the evaporator coil can prevent your AC from providing effective cooling. It can also be a sign of an airflow problem, which can be due to a malfunctioning fan.
- Unpleasant Odors: Mold buildup on the evaporator or the presence of bacteria can trigger odors that proliferate throughout your home. Over time, these issues can damage your AC and be harmful to your health.
- Higher Temperatures: If the temperature in your room is higher than the thermostat setting, it can be due to an evaporator coil problem, such as a clog. This is a good reason to call an AC repair.
- Rising Energy Bills: When the evaporator coil isn’t working properly, it can reduce the energy efficiency of the HVAC system. You can therefore see energy savings by properly maintaining the evaporator coil and other major components.
- Poor Operation: The AC may turn on and off more quickly than usual. As it continues this pattern of short cycling, your house doesn’t get as cool as it should. Eventually, the unit will experience a catastrophic fault and not turn on.
- Noise: Audible indicators of a bad evaporator coil include grinding, clanging, hissing, or squealing sounds from your air conditioner. These are a sure sign the coil will fail without professional service.
Our Evaporator Coil Services
Cleaning an evaporator coil is important because it prevents the issues a dirty coil can cause. Accumulation of dirt can:
- Increase energy bills
- Reduce cooling capacity
- Raise system pressure
- Lead to poor heat absorption
The dirt can also cause ice and frost to build up on the coil. While some people choose to clean their evaporator coil themselves, it can be a difficult process and requires special tools. HVAC professionals are trained and equipped to safely and efficiently clean AC coils.
An air conditioning contractor can also inspect the evaporator coils to determine if a repair is needed. They can spot the cause of issues such as frozen coils, moisture, or a lack of cool air. Whether your evaporator coil can be repaired or needs to be replaced, you can count on a professional to get your AC working again. At The AC Hero, our technicians are highly skilled, honest, and provide results backed by our 100% guarantee.
How to Prevent Evaporator Coil Faults
It is possible to prevent AC evaporator coil problems. Volatile Organic Compounds (VOCs) can cause damage if they get into your coils. Reduce them by avoiding use of VOC-containing products. Installing a whole-house air cleaner that uses UV light can break down these compounds. You can also install a coil lamp that cleans the coils without having to do so manually. Also, make sure your system is running with the right amount of refrigerant; this can also avoid compressor damage and failure.
When cleaning your evaporator coil, make sure you use the appropriate cleaning attire, including protective gloves and goggles. Coil cleaners are acidic so can burn your skin. It’s also important to use the right chemical solution, preferably an alkaline-based one, and try not to use too much pressure or you might damage the coils or cause the solution to splash. If cleaning the evaporator coil seems too difficult, you can always contact us to get this taken care of.
Here are the steps:
- Make sure your AC is off.
- Remove the AC from the wall and take it to your yard.
- Expose the condenser unit.
- Rinse the coils with a garden hose nozzle and let them drain.
- Spray the coils with the chemical solution, then scrub them with a foam; let the solution stand for 15 minutes.
- Rinse the coils thoroughly, pausing frequently to avoid liquid from overflowing, and let dry
- If you have a wet dry vacuum, remove remaining water/dirt from the drainpan.
Now, this is easier said than done. There are components in the AC system that should not get wet, such as the wiring and the compressor. The evaporator coil is an important component of your AC system. It is the part that absorbs heat from your room, and it is where the cold refrigerant passes through to reduce the temperature in your house.
If the evaporator coil breaks or gets dirty, chances are you are also inhaling dust. Call a professional to help you clean the coils regularly. If you want to do it yourself, it makes perfect sense to get adequate training. Once a technician arrives, watch how they dismantle the AC and clean the coils. You should also know how to put them back together and re-install them.
