Your AC system’s job is to cool your home. So, if you’re turning it on and only getting warm air coming out of your vents, it’s time to call an HVAC professional for repairs.
Warm air can indicate a broken thermostat or a failing compressor. It could also mean there are duct issues somewhere else in your house.
Your Cooling Bills Have Skyrocketed
Expecting your energy bills to increase during the summer is one thing, but seeing your electric account jump significantly from last year is unique. This could indicate that your AC is putting in extra effort to keep your house cool and should be inspected by a professional for repairs.
Strange sounds from your air conditioning system should never be ignored, as they could mean that parts are loose and in danger of falling off. If you hear grinding, squealing, or scraping noises that weren’t there before, immediately contact a professional AC repair in Garland, TX, to prevent the sound from worsening and damaging your system.
When your air conditioner operates, it should only blow cool air out of your vents. If you notice warm air coming out of your vents, it indicates something is wrong and must be repaired immediately before the problem worsens. This could be due to a clogged air filter, frozen evaporator coils, duct leaks, or low refrigerant.
You’re Hearing Loud Noises
If you’re hearing strange and loud noises coming from your AC unit, it could be a sign of severe damage or an imminent failure. Fortunately, several common air conditioning problems can be identified early by listening to specific sounds.
If a high-pitched squealing sound is coming from your air conditioner, it could mean that the belt in the compressor portion of your system must be replaced or the motor bearings are going wrong. Both issues are typically easy to resolve and can save much money in repair costs by being addressed during routine maintenance.
Rattling and banging sounds from your air conditioner may result from loose screws or fasteners. This issue is best left to trained professionals who can ensure that your HVAC system is safe and secure.
Other possible sounds include a humming noise, which is perfectly normal. However, if you hear cracking or popping noises, these may be signs of a refrigerant leak that can cause your air conditioner to work less efficiently or stop working altogether.
Your AC Is Smelling Musty or Burning
If you notice a musty or burning smell when you turn on your AC unit, it’s a clear sign that something is wrong with your system. The scent is most likely caused by mold or mildew spores circulated throughout your home by your AC unit. These spores can lead to upper respiratory health issues for you and your family.
Your air conditioning unit isn’t supposed to produce any odors at all. If you’re noticing any strange smells, it’s time to call in a professional HVAC technician for inspection and repair services.
A burning smell could indicate that your AC unit is leaking refrigerant. A technician can detect and fix the leak before it causes further problems.
Other strange odors you might encounter include a foul or pungent odor that reminds you of raw sewage. This could be a sign that your air conditioning unit is releasing methane, which is a dangerous gas. The smell of burning wires is another symptom that your AC unit may need repairs.
Your AC Is Excessively Humid
If the air in your home feels cool but sticky, it could be a sign that your AC isn’t dehumidifying properly. The evaporator coil in your AC unit helps to control indoor humidity by pulling moisture from the air and channeling it into the condensate drain. Suppose you’ve noticed any strange odors or a musty or burning smell coming from your air conditioner or have found a mystery liquid around the system. In that case, it’s time to call an HVAC technician for professional repair services.
Aside from the quiet hum your AC usually produces, it shouldn’t make any other sounds, especially grinding, grating, or scraping noises. These can indicate that the belt is worn down or something else is loose within the unit. It’s also important to pay attention to whether or not the airflow is strong through your vents. Little to no airflow could indicate a blockage somewhere in the system or a problem with your ductwork. The sooner you catch these problems, the less likely they’ll lead to expensive repairs or system failure.
Your AC Is Past Its Lifespan
When your AC system is over ten years old, it’s likely time to start shopping around for a new unit. While it’s great that your team lasted this long, it was bound to need repairs eventually and will most likely require a replacement soon.
In many cases, a new air conditioning unit will also work more efficiently than your current one, saving you even more money on energy costs and preventing overworking the system.
Some say the best way to keep your home comfortable and avoid expensive AC repair costs is to ensure that you get regular professional system maintenance. This includes replacing air filters, checking the thermostat settings, and ensuring no debris or dust is blocking the air vents. In addition, make sure to check for any moisture leaks, as they could be signs of a refrigerant leak, which is a dangerous problem. If you notice any warning signs, contact a local HVAC technician to schedule an inspection and AC repair services. This will save you from unexpected and costly breakdowns this summer.
It’s recommended to have your AC unit serviced at least once a year. Regular maintenance helps identify and address any potential issues before they escalate.
While there are some simple maintenance tasks you can perform, it’s best to leave complex repairs to professionals. DIY repairs can lead to further damage or void your warranty.
The average lifespan of an AC unit is around 10 to 15 years. However, regular maintenance and prompt repairs can extend its lifespan.
A freezing AC unit can be caused by issues such as low refrigerant levels, dirty air filters, or a malfunctioning blower motor. It’s best to have a professional diagnose and fix the problem.
To improve energy efficiency, make sure to clean or replace air filters regularly, seal any air leaks in your home, and keep the thermostat at an optimal temperature.
Maintaining a well-functioning AC unit is essential for a comfortable living environment, especially during hot summer days. By paying attention to the signs that indicate your AC unit needs professional repair services, you can address problems promptly and avoid further damage. If you experience insufficient cooling, unusual noises, frequent cycling, foul odors, or high energy bills, it’s crucial to call in a professional technician. They will diagnose and fix the issues, ensuring that your AC unit operates efficiently and provides optimal cooling performance.
