Be sure to run the unit before starting any repairs. Visually inspect that the disconnects/breakers are on, and will continue to be on after you leave.
Repairs done by professionals are expensive, especially when they involve major repairs or replaces. It can be frustrating to wait for an appointment.
Filters or coils that have become dirty
The air filters in your home are vital for cooling. However, they can become clogged over time with dirt. This can cause airflow to be restricted, and the HVAC system will have to work harder in order to keep your house cool. This additional pressure can lead a number problems, including higher energy bills and poorer air quality indoors. The risk of developing these problems can be reduced by maintaining a regular schedule for changing your filters.
The evaporator coils should be cleaned by an AC specialist as soon as possible after they get dirty. You could damage the copper and alloy metals used in the coil if you try to clean it yourself. This can result in expensive repairs or system failure. It is best to have an expert perform regular maintenance, and to change the air filter according to manufacturer specifications.
The fan motor will have to work harder, consuming more energy. The extra stress can eventually cause the fan to fail, which can damage the motor or cause overheating of the whole system. The air filter can be changed easily and cheaply to increase the efficiency of HVAC systems as well extend their lifespan.
The coils used to cool the evaporator in an air conditioner are exposed outside air. This air is a good source of moisture, as it contains dew. When the temperature drops below freezing, the moisture drips on the coils and freezes. Ice will melt as soon as your air conditioning system is switched on but then will freeze again when the system is shut off. This could cause damage to your system.
When you see ice on the evaporator, turn off the air conditioner and switch on the heater. Wait until the coils are completely defrosted before you turn on the air conditioning. Make sure you use a commercially-rated cleaner that is safe for the evaporator coils of your system. Avoid household cleaning products as these can contain acids that could harm the coils. Test your system by replacing the airfilter.
Refrigerant Leaks
A leak in your system is a major issue that needs to be dealt with immediately. Your cooling system may stop working or even fail if there is a leak. To detect refrigerant leaking, air conditioning technicians use electronic sniffers or ultraviolet (UV) sensor equipment. To repair the leak, they must also evacuate all refrigerant as per EPA guidelines.
Copper coil corrosion is the leading cause of refrigerant leaks. Copper coils exposed to the elements can be damaged overtime due to exposure of formic acids, which are present in household chemicals such as air fresheners or cleaners. The corrosion of the coils can damage them and lead to holes, which then make it easier for leaks. In some cases, it may be best to replace the coils rather than try to fix them.
The HVAC system can have other issues such as electrical issues or a damaged fan motor that could lead to refrigerant leaks. Experts can detect problems, such as blown fuse which indicate that an electrical issue needs to be addressed. The experts can identify broken components such as damaged capacitors.
An evaporator and condenser that are worn out can cause leaks. The cooling system is dependent on them and they can be costly to repair. It can be very difficult to clean a leaking coil. If you hear oozing coming from your vents, it’s important to call an expert.
It is important that leaks are repaired by a qualified technician, as they could pose a threat to safety. Freon gas is dangerous, and should only by handled by professionals. You should not attempt to repair these problems yourself, as you may cause more damage to your system and even put your family at risk.
Broken Compressor
The compressor is the heart of your AC system. It converts the liquid refrigerant chemical into a gas that is then pumped to the rest of your system in order to cool down your home. In the event of a compressor failure, this gas will not be converted into cool air. This could make any HVAC problems worse.
A failed compressor is evident by the vents not blowing cold, which are usually not working. If you notice this, shut off the system and contact an AC professional right away. Also, be aware of your monthly electricity bills because an older, faulty compressor could cause them to skyrocket.
When the system is switched on, it may not be able to turn off. These symptoms indicate that the clutch of your compressor on the drive pulley has become stuck or is seized. It is possible to solve this problem by disconnecting and manually turning the clutch. You may need a new compressor if the compressor has trouble turning.
A compressor that is leaking refrigerant could cause damage to the motor. This could happen because the compressor leaks refrigerant. This can cause motor damage.

This can be caused because of a defective valve at the unloader which does not allow pressure to rise above the limit.
A compressor piston or seal that is faulty or inoperable can cause air leaks. Open your tank drain to allow air to escape. This will test the pressure on your compressor. Compare the pressure reading on the gauge of your unit to the pressure switch on your compressor.
Not least, it is important to follow the recommendations of the manufacturer for the amount of oil you put into your air compressor. This is crucial, as an insufficient amount of oil could prevent your compressor’s starting or even stop it working after it has started.
Damaged Ductwork
Damaged HVAC ducts may affect air distribution in your home. The dirty ductwork, and any leaks in the ductwork, can result in poorer quality indoor air as well as higher energy costs.
You should contact an HVAC specialist immediately if there are any leaks or holes in your ductwork. A technician will inspect your ducts, and then fix them using a mastic sealant and metallic tape designed specifically for ductwork.
Leaky air ducts may allow significant air to escape. This extra air will make your cooling and heater systems work harder, increasing energy costs.
Listen to the vents. The joints of your ductwork may not be properly sealed if they make a rumbling, vibrating or rattling sound. This can make your ductwork more susceptible to fires or other structural issues.
Mold or mildew growing on your ducts can also be a sign that they are in need of repair. These substances may cause odors in your home. Call an HVAC specialist as soon as you can to clean the vents.
Your ductwork can be damaged by heavy objects, pests and even pests. Nesting animals such as mice, rats, and squirrels have been observed in the ductwork. Their droppings could cause respiratory issues or health issues for your family. Rodents can use flammable substances to build their nests.
The weight and size of objects stored in an attic or garage may cause the ductwork to collapse. They could also become twisty, which can block airflow.
You may have noticed a sudden increase in energy bills. This could be due to damaged or faulty vents. Professional HVAC technicians can repair your ductwork easily. It is as simple as turning off the air conditioner, finding the leaks, and sealing them with a metallic tape.
