The evaporator coil serves a critical purpose in the cooling process of most AC systems. You must keep the coil in good condition to ensure optimal home comfort. When coils malfunction, the cooling output reduces and the energy use rises. We handle evaporator coil repairs in the Garland, Texas, area where people depend heavily on their AC systems in the subtropical climate.
The evaporator coil works in the area that transfers heat from your home to the exterior exhaust and provides chilled coolant that converts to a low-pressure gas. As the air in your home passes over the evaporator coils, the coils extract heat and humidity. The cooled air passes into your home, and hot air and condensation are eliminated from the exterior part of the system.
Our years of experience working in the Garner and Metropolitan Dallas/Fort Worth area uniquely prepare us to deal with any emergency HVAC services – especially cooling.
Signs of Damaged Coils
The role of evaporator coils is critical to the cooling process, and signs of damaged coils include the following:
- Warm air coming from a dirty coil
- Leakage of coolant
- Frozen evaporator coil
- Physical damage to the coils
We at On Time Experts can make any necessary repairs or advise you that you need to replace the system. The most common evaporator coil repairs include the following.
1. Warm Air From a Dirty Coil
Warm air coming from your AC system usually indicates a problem with the evaporator coil. The system runs as normal but doesn’t cool the air. You usually need the professional advice of an HVAC technician because other issues can cause warm air. These include clogged filters, frozen evaporator coils, refrigerant leaks, power interruptions, and problems with ducts. Blocked airflow also causes a loss of cooling efficiency. That’s the primary reason that the first step is replacing your system’s air filter.
At On Time Experts, we offer professional cleaning of evaporator coils, which often solves the problem of not cooling properly. When dirt builds up, it can insulate the system from the cooling properties of the refrigerant. It’s best to rely on a professional, HVAC-certified technician to avoid the hazards of further damage to your system. We use the proper types of cleaners for your coils that are safe for metal parts. We can also replace your faulty evaporator coil to restore air conditioning cooling functionality. The coil costs far less than replacing an entire system.
2. Leakage of Coolant
The leakage of coolant can decrease cooling power because it makes the system no longer capable of cooling air. There are some signs to look out for that indicate a coolant leak.
One sign of a coolant leak is if you notice any “sweet” smells around the system’s components. If your compressor turns on and off frequently without cooling, that could be another sign of leaking coolant. If you’re hearing strange noises coming from your unit, or you’re unable to start your air conditioner, these could also mean you have a coolant leak.
Leaks can easily result in reduced pressure, which prevents the compressor from activating. Professional technicians certified in HVAC repair are the best choice for determining AC problems. Knowing the signs of an evaporator problem is the first step, but you should call us at On Time Experts to confirm the diagnosis, make repairs, or recommend unit replacement. If you notice a problem with cooling not explained by a big increase in outdoor weather temperature, call us to discuss the matter. You can save considerable cash by hiring us to check your system or provide regular system maintenance service.
3. Frozen Coil
The evaporator cools by removing heat and humidity from the air. A damaged evaporator can freeze up with frost or have solid layers of ice. This affects the unit’s ability to cool. Turning off a frozen air conditioning unit is the first step, and that sometimes provides a temporary reprieve when all the ice is melted. Evaporator coils freeze for many reasons that include clogged filters, frost on the coil, and physical damage to AC components. Other reasons include the blower motor isn’t working properly, there’s a blocked vent, or the air handler is dirty. Your professional technician can determine the reason by removing the panel and checking the heat register.
4. Physical Damage to the Coils
Physical damage to your coil can certainly require a repair or replacement to restore your system’s cooling efficiency. Hissing and banging are common problems related to damaged condenser components. Your system actually has two types of coils: the evaporator and the condenser. Condenser coils are usually located outdoors while the evaporator usually resides within the indoor unit.
The fins on both types of coils are delicate and can easily sustain physical damage. Potential malfunction causes include coolant leakage and damaged fins. We can often repair damaged fins with the proper fin comb. Regularly cleaned and maintained, your evaporator coil could last from 10 to 15 years or longer. Physical damages can come from environmental causes and the buildup of dust, pollen, and other contaminants that can encourage coil freezing and cracking. You should ask our technician about the benefits of a maintenance contract to keep your evaporator in top shape for the maximum coil and AC life expectancy.
The Value of Professional HVAC Maintenance
Regular HVAC maintenance and repairs prevent more expensive repairs and system replacements, extend system life and efficiency, and reduce your energy bills. Regular maintenance can reduce energy bills by as much as 30% according to the Department of Energy. Maintenance also extends the life of your AC system and prevents you from needing a major installation. Regular repairs save time, installation costs, and headaches because choosing a new system often takes a lot of time, structural measurements, and alterations. Most manufacturers require proof of regular maintenance to honor warranties.
Maintenance also improves your family’s quality of life because your system operates more efficiently and generates cleaner air that’s free of spores, contaminants, pollen, and other allergens. Your functional HVAC system provides year-round comfort and security from the effects of cold or heat. We can even provide advanced air filtering for dander, bacteria, and other pathogens. Preventative maintenance also protects your family from carbon monoxide poisoning.
