When the temperature outside heats up in the summer, you need an air conditioner to keep your house cool and comfortable. Air conditioners aren’t impervious to problems, and some can affect the temperature in your home, and some can put your home and family at risk.
If your air conditioner experiences any of the following problems, it’s best to call an AC repair company immediately. Trying to ignore the problem won’t make it go away, and the unit should be fixed before further issues occur.
#1 Refrigerant Leak
Your air conditioner relies on refrigerant to produce cold air, and the unit won’t function properly if there’s a leak. There are a few ways to tell if there’s a refrigerant leak, including:
- Pooling greenish-yellow fluid around the unit
- The air conditioner produces warm air.
- The unit makes a hissing sound.
Wear and tear can cause a refrigerant leak and occurs when the rubber seals around the valve stems or on the service valve have worn out. Leaks can also happen when acid eats away at the copper tubing, creating a pinhole that allows the refrigerant to leak.
If your air conditioner is leaking refrigerant, it’s best to call an AC repair company in Lewisville, TX, immediately.
If the unit was installed after 2010, an HVAC tech can fix the leak and refill the refrigerant. If the unit was installed earlier than 2010, it cannot be repaired. Older units use R-22 refrigerant that the EPA deemed toxic and harmful to the ozone layer. A partial ban was placed on R-22, causing manufacturers to build units that use a different type of refrigerant. On January 1, 2020, R-22 was banned entirely in the United States and is no longer available. The tech won’t waste time trying to fix the leak because they won’t have R-22 to refill the unit, and your only option is to replace your air conditioner.
#2 Minimal Airflow
You should feel a powerful rush of cold air from the vents when the air conditioner runs. If you feel minimal airflow, you’ll need to call an AC repair company for an appointment. It’s best to make the call immediately because poor airflow will cause the air conditioner to work harder to keep your house cool, consuming more energy and increasing your electric bills. Also, the extra work will strain the unit, reducing its lifespan.
A few issues can restrict the airflow, including:
- A buildup of dirt, dust, and debris in the ducts, preventing adequate airflow
- A break in the ducts or a failed seal allowing the cold air to escape from the ducts before reaching the vents.
- A broken blower and the air won’t be forced from the unit, through the ducts, to the vents, resulting in minimal airflow.
An AC repair company can send a tech to inspect the air conditioner and the ducts to determine why there’s poor airflow so they can resolve the problem.
#3 Strange Smells
You shouldn’t smell anything when your air conditioner runs. If the unit produces a strange smell, there’s a problem that can put your home and family at risk, and you should call an AC repair company in Lewisville, TX, immediately.
A moldy or mildew smell often indicates mold in the air ducts. It’s not uncommon for mold to grow in the ducts because they’re dark, and when it gets humid in the house, condensation can accumulate in the ducts, creating the perfect environment for mold.
When the air conditioner runs, mold spores will circulate in the air, creating a health hazard. Mold exposure causes several health problems, including allergies, respiratory problems, skin rashes, chronic headaches, and a weakened immune system. If an HVAC tech finds mold in the ducts, an antimicrobial fogger will eradicate the mold.
A burning smell indicates a wiring issue that could start an electrical fire that could destroy your house in minutes. An AC repair company can send a tech to find the wiring issue and fix it before a disaster occurs.
#4 The Unit Isn’t Producing Cold Air
The most obvious sign it’s time to call an AC repair company is if you feel warm air coming from the vents in your home. Before making the call, check the thermostat setting. The unit cannot produce cold air if it’s not set to the cooling mode. The same is true if the fan isn’t set to auto and if it’s colder in the house than the thermostat setting.
Next, check the air filter. If it’s covered in dirt and grime, air won’t move through the unit, causing it to overheat and produce warm air.
If everything checks out on your end, make the call. A few issues can prevent the unit from producing cold air, including:
- A faulty compressor
- Frozen evaporator coils
- A refrigerant leak
- The unit has reached the end of its lifespan.
An AC repair company in Lewisville, TX, will send a tech to your home to check the unit to determine the cause and fix the problem, allowing the unit to produce warm air.
