Air conditioning systems usually deliver reliable cooling, but there are many ways in which the process can go wrong. If your air conditioner is not blowing cold air, the problem could lie with the filters, the compressor, or some other part entirely. You need a trusted AC repair team to correctly identify the fault and fix it for you.

Southport Home Services repairs all kinds of problems with home air conditioning systems. You can call on us any time your unit stops blowing cold air. Listed below are a few of the most common causes of this problem that our experienced technicians look out for.

Clogged Air Filters

Dirty air filters are a common problem affecting home air conditioners. By blocking the flow of air through the system, clogged filters can lead to no cold air coming from the vents. To make the air conditioner work properly again, a technician must clean or replace the filters. This simple maintenance task can have a big positive effect on the performance and efficiency of your AC system. You might even notice that the air in your home seems cleaner as a result.

Frozen Evaporator Coils

When we clean or replace your filters, we also check the evaporator coils. Clogged filters can cause cold air to back up inside the unit, freezing the evaporator coils. When this happens, it is essential to clean the coils before the system can work well again. Our technicians can ensure the evaporator coils are in good condition, or replace them as needed. By also replacing the filters, we can help to ensure that the coils will not freeze again any time soon.

Refrigerant Leaks

AC systems contain refrigerant fluid, which absorbs heat to cool the air that passes through the unit. If the refrigerant is leaking from your air conditioner, then it will not be able to deliver adequate cooling. It is essential to also find the leak and fix it. Our technicians always take a comprehensive approach to check for leaks to ensure none go unnoticed. Call us right away if you suspect your unit is leaking refrigerant fluid, which could create further problems besides no cold air.

Thermostat Problems

Before you call for AC repair, it is always worth checking your thermostat settings. Try the unit on both “on” and “auto” modes to see whether it emits cold air for either setting. If tweaking the thermostat settings produces no satisfactory results, please call us so we can check the system for you. Replacing the thermostat is a relatively straightforward repair for an experienced technician. It also allows you to upgrade to a programmable thermostat, which could help you to save energy.

Condenser Coils Need Cleaning

A build-up of dirt on grime on the condenser coils can prevent an air conditioner from working properly. The role of the condenser is to remove heat from the air, which it can’t do properly if the coils are coated in dirt. We can take your unit apart to access the condenser coils and clean them thoroughly. To prevent a future build-up of dirt from occurring, be sure to schedule regular tune-ups for your air conditioner.

Leaks in the Ductwork

If you have a ducted air conditioning system, then tears or loose joints in the ductwork could be the problem. Holes in the ducts allow cold air to leak out behind the walls and in crawl spaces. That’s no use when you need it to cool your living space! Leaks in the ducts can occur due to rodent infestations or just simply age, wear, and tear. Whatever the cause, you can rely on us to put it right.

Clogs in the Drain Line

Water drains away from your air conditioner through the drain line. If this line becomes blocked, then water collects inside the unit, potentially causing damage to important AC parts. You might even notice water leaking from the unit, leading to mold or mildew growth. Give us a call if your drain line is blocked and needs to be cleaned or repaired.

Problems with the Fan

The role of the fan is to drive cold air from your air conditioner into and around your home. If the fan is dirty, has a worn-out belt, or has a broken motor, it might not turn properly. As a result, the air conditioning system cannot blow air with the necessary force to adequately cool your home. Get in touch and we will repair or replace the fan to get the unit working again.

Electrical Faults

If your air conditioner is not blowing any air at all, then an electrical fault might have caused it to stop working. Try resetting the circuit breaker for the circuit that the system is on. If the air conditioner keeps tripping the circuit breaker, please call us. Any faulty electrical appliance can be dangerous if it is not repaired quickly.

What to Do if Your Air Conditioner Stops Blowing Cold Air

If your air conditioner stops blowing cold air, you need to call for AC repair service. You can easily test whether the unit is blowing air at the correct temperature by putting your hand in front of the vents. The air blowing from the AC should feel cold compared to standing air. If the air is warm, then it is clear that something is wrong. Southport Home Services can help if you give us a call today.

If cold air is coming from the vents, but your home is still too hot, try moving furniture away from the vents. This simple step could help to improve the distribution of cold air around your home. If this simple tip doesn’t help, contact us and we will come up with a better solution. It could be that your air conditioner is undersized for your home, or it could be short cycling. Whatever the problem, we can repair the air conditioner or replace it with a more suitable one.
