All You Need To Know About AC Repair

All You Need To Know About AC Repair

Your family depends on air conditioning for temperature, humidity, and air quality control. When you need AC repair, your home can get downright uncomfortable. It’s important not to delay a repair, whether it’s a simple DIY fix or you need a technician. Below, we’ll detail how to troubleshoot your system, know when to call for help, and some common AC repair issues.

Troubleshooting Your Central AC

Some common issues you might be able to correct include:

  • The Condenser Doesn’t Turn On: Check whether the AC has power. If not, plug it in, switch the system on, or if the circuit breaker has tripped, reset it. Also, reset the thermostat if it’s set too high. However, other possible issues include a faulty compressor or motor.
  • The Condenser Unit Cycles to Often: If the condenser keeps turning on and off frequently, the condenser coil and fins may need to be cleaned. You may also need to clean the evaporator or remove grass, weeds, leaves, and other debris from around the unit.
  • The AC Is Cooling Unevenly: Check whether any vents are closed and open them, or clean or change the filter. It’s also possible the air distribution system may be out of balance. You’ll need an HVAC professional to inspect the ductwork and related components to see what to do.
  • There’s Not Enough Cool Air: The thermostat may be set too high, so lower the temperature. If the issue is caused by a dirty condenser or evaporator, clean the system, and if the condenser is blocked, remove debris. If any components are faulty or there’s not enough refrigerant, you’ll need a professional to address the problem.
  • Ice Forms in the AC Unit: Try operating the unit on the fan setting. The ice should melt and your system should work normally again soon. If the problem persists, there may be a fan problem, restricted airflow, or an issue with the coolant level.
  • There’s Low Air Pressure or Warm Air: Check the AC filter; if it’s dirty or clogged, replace it. See whether performance has improved once you’ve changed the filter and cleaned the system. If not, there’s likely an internal problem or the system isn’t the proper size.

Common Repair Issues

AC repair technicians tend to encounter a few common issues. Therefore, they are ready with the knowledge, tools, and parts to fix the issue when they arrive. Some of the most common air conditioner problems include:

Drainage Issues

Condensation forms as air is cooled in the system. High humidity can cause the drain pan to fill up and overflow, while a clog in the drain line can cause water to pool up on the floor. Excess condensation can lead to reduced performance and AC damage. A technician can clear clogs, treat the line to prevent algae growth, and perform other repairs.

Refrigerant Leak

AC refrigerant absorbs heat and transports it to components that release it outside. Low refrigerant levels typically mean there’s a leak and can overwork your air conditioner. Since coolant can be toxic to people and dangerous to the environment, you should call a professional ASAP to fix the problem. 

Faulty Compressor Fan

A malfunctioning or failed fan inhibits heat transfer. Aside from your home not getting cool, this can cause the compressor to overheat and fail, requiring major AC repair. At the very least, the system may keep shutting off because the fault triggers the safety controls. Repairing or replacing the fan is less expensive than installing a new compressor.

Frozen Coils

If the condenser coils keep freezing, there may be an airflow issue or obstruction such as a dirty filter or blocked return duct. Low refrigerant is another possibility. Therefore, it’s important to have the issue diagnosed and fixed by a skilled technician.

Leaky Ducts

Ventilation issues can cause cooled/treated air to escape from your home before it has a chance to cool rooms. This can reduce AC performance and efficiency. Holes and tears in ducts can also let outside air in, potentially causing pollution in your home including dust, mold, and viruses that can lead to a range of health issues. Professional duct sealing can quickly resolve small leaks and improve efficiency.

How Does Central Air Work?

How Does Central Air Work?

In its modern form, air conditioning has been around since 1902. Willis Carrier’s invention has been improved and modified over the years, leading to many cooling options today. But split-system air conditioning (or “central AC”) is still the most popular. Aside from air temperature, it can control humidity, airflow, and air quality. Continue reading for a more in-depth look at the answer to the question, “How does central air work?”

Parts of a Central Air Conditioning System

Together all the system’s components provide cool air to your entire home, unlike a window AC or mini-split unit that serves a single room. To help you understand how a central AC system works, here’s a look at some of its major parts:

  • Outdoor Unit: A casing that houses the compressor, condenser coil, and fan, it sits on a concrete pad next to an outside wall.
  • Indoor Unit: Includes the evaporator coil and fan that circulates air throughout your home; it’s usually a furnace or fan coil.
  • Ductwork: Connects the indoor unit to registers/vents in rooms and living spaces, allowing conditioned air to circulate.
  • Copper Tubing: Provides a conduit for refrigerant, in vapor and liquid form, to flow between the outdoor and indoor units.
  • Thermostat: Reads room temperature and controls the system based on whether air temperature matches set thresholds.

How the Process Works

Here’s a simple view of how central air works. Warm air blows across a cold coil inside your home. The cold refrigerant absorbs heat from the air and becomes a gas. Colder air is then blown back into the house. On the outside, gaseous refrigerant is compressed as it enters the outdoor unit’s coil. As the refrigerant converts back to a liquid, heat is released. A fan directs the heat away by pulling outdoor air through this coil.

A more detailed look at the central air conditioning process is as follows:

The Thermostat Sends a Signal to the AC

Usually mounted on a wall in a centralized area, the thermostat constantly senses air temperature. When the ambient indoor temperature rises above what you set on the thermostat, it automatically sends a signal to a circuit board.

The Blower Motor Starts Running

Electricity starts flowing so the blower motor can turn on. The fan in the indoor unit starts pulling hot air from inside the house. As air flows through return air ducts, it is filtered, removing dust, lint, and other particles and pollutants. Meanwhile, the outdoor condenser starts to run.

Air Passes Over the Evaporator Coil

Filtered, warm air passes over the evaporator coil, through which liquid refrigerant flows. The heat from the air is absorbed by the refrigerant, causing it to turn into a gas. Cooled air blows through air ducts to vents in each room. Meanwhile, a condensate pan picks up excess moisture that flows into the drain line to the outside unit.

Refrigerant Gas Is Sent Outside

A copper tube delivers gaseous refrigerant to the compressor, which pressurizes the gas. The heat is evacuated via coils or metal fins and dissipated by a compressor fan. As the heat is released outside, the refrigerant turns back into a liquid.

Refrigerant Returns to the Indoor Coil

Coolant returns inside through a copper tube. An expansion device controls how much refrigerant flows back to the evaporator coil. Cold refrigerant can then absorb more heat from your home in a continuous cycle. The process continues until the system achieves the desired temperature, at which point the thermostat will cycle the system off.

Types of Central Air Conditioners

The most common type is the split central AC. Indoor air handlers and outdoor units contain most of the system’s components. The evaporator coils are near the air handler or furnace. Packaged central air conditioners work similarly, except all components are in one unit; which pumps warm air from inside and returns cooled air in exchange. Usually installed on the ground, a packaged unit may also be roof-mounted.
