Check for a dirty filter if your air conditioner is not producing cool air. Clogged filters restrict airflow and freeze up evaporator coils.

Air Conditioning Repair

Consider the brand of your AC unit. Homeowners can save a little on repair costs by choosing a value brand over an expensive one. Contact Air Conditioning Repair Van Nuys for professional assistance.

If warm air is coming out of your vents, it may be a sign that the AC unit is nearing replacement.

Dirty evaporator coils are one of the most common AC repair issues. The coil absorbs the heat from your home and transfers it outside, but if it’s covered in dirt and debris it can’t do its job as well. Dirty evaporator coils also restrict airflow, which can lead to cooling problems in your home. The best way to keep your evaporator coil clean is to change your air filter frequently, and vacuum the vents regularly.

Your owner’s manual should have detailed instructions on how to access the evaporator coil safely, and your AC expert can show you how during your regular maintenance visit. Once you’ve gained access to the coil, make sure the power to your unit is off and use a soft-bristle brush or shop vac to remove loose dirt and sediment. Be careful not to damage the fins of the evaporator coil. Avoid acidic cleaners, which can cause corrosion and shorten the coil’s life.

Frozen evaporator coils can be extremely dangerous to your air conditioning system. If the coil can’t absorb heat, it will turn to condensation and the water will freeze. If this happens, your AC will stop working completely and your home will become uncomfortably hot. Your technician will be able to diagnose and fix the problem if you notice any ice on your evaporator coil.

A dirty evaporator coil causes your air conditioner to run longer cycles in order to cool the home, and this can increase wear and tear on other parts of your AC. This can lead to expensive repairs and an even higher electricity bill.

The other function of the evaporator coil is to pull moisture from your indoor air, and a dirty one can’t do that as effectively. You may notice that your indoor humidity is a little higher than normal, and your AC will work harder to compensate.

A clean evaporator coil allows your air conditioner to run efficiently, and it will help you save money on your energy bills as well. The easiest way to maintain your evaporator coil is by changing your air filter on a regular basis and scheduling routine AC maintenance twice a year.

Dirty Compressor Coils

There are two coils in your air conditioning system: the evaporator coil (indoor) and the compressor coil (outdoor). The compressor coil is responsible for moving energy out of your home. Unfortunately, this process can be impeded by dirt and dust that accumulates on the coil’s surface. This can lead to reduced energy efficiency and higher energy bills.

The air conditioner’s compressor and evaporator coils are protected by a protective layer of oil, which helps prevent metal-to-metal contact that would otherwise wear down these important components. The oil also lubricates the motor and bearings, helping them last longer. However, when the coils are dirty, the oil is unable to adequately lubricate these parts, leading to excessive wear and tear that shortens the lifespan of your air conditioning unit.

Dirty condenser coils are one of the most common air conditioning repair issues in the industry today. When the coil is clogged, it restricts airflow and causes the refrigerant to lose its cooling capabilities. This can lead to high utility bills, shortened compressor life, and noisy operation.

To clean the coil, first turn off the power to your outdoor unit. Next, remove any debris or plants that may have accumulated around the unit’s exterior. Finally, disconnect the condensation drain line and use a shop vac to suck away any remaining dirt and dust. Once the coil is accessible, your dealer will apply a cleaner specifically designed for air conditioning condenser coils and follow the manufacturer’s instructions to thoroughly rinse it with water.

A dirty evaporator coil can cause a number of different problems, including poor indoor air quality, higher energy bills, and even ice formation. If you notice any of these signs, it’s time to call for a professional AC repair service. A technician will be able to identify the problem and determine whether or not it is caused by a dirty evaporator coil or a larger issue with your air conditioning system. They will then recommend the proper repairs to fix the problem and keep your home cool. The sooner you address the problem, the more money you can save on your energy bills.

Damaged Coolant Lines

Coolant lines are vital to the cooling system of a vehicle and an air conditioning system. However, a leak in the line can lead to low coolant levels and an inability for your system to properly cool your home.

While it is difficult to diagnose a coolant line leak without removing the hoses and inspecting them for signs of degradation, there are a few things you can try. First, drain the coolant using the petcock located on the lower part of your radiator. Next, fill the coolant system up with a hand pump or compressed air to pressurize it. A hand pump is a great option because it allows you to easily control the amount of pressure being put into the system. Once the coolant reaches its pressure rating, locate the leaking hose and remove it from the engine and radiator.

If the hose is Bristled, cracked, or deteriorated, it will need to be replaced. For the remaining hoses, you can test them for leaks by wiggling them and looking for any moisture or drips that may be present. If you find a hose with a loose clamp, you can tighten it using pliers or a screwdriver. You can also use a leak detection dye to help you identify the source of the coolant leak.

If you are able to locate the leak and fix it, you can go back to your house and turn on your air conditioner to see if the problem is solved. If the air isn’t cooling, it could mean that there is a lack of refrigerant in the system and this is another problem that should be left to a professional to handle. If the refrigerant level is too low, a professional can recharge the system with the correct type of refrigerant to solve the problem. If the refrigerant isn’t the issue, it could be a problem with the compressor or evaporator coils. An HVAC technician can diagnose this problem by examining the unit and testing it. They will then be able to determine what the best course of action is for a home AC repair.

Dirty Thermostat

If you’re feeling cold air despite the setting on your thermostat, or you notice that the temperature displayed isn’t a true representation of the room’s actual temperature, this may indicate a problem with your thermostat. A dirty sensor can cause your thermostat to display inaccurate temperatures, but it’s relatively easy to fix. Before calling for an HVAC repairman, make sure your thermostat has a working display by replacing the batteries and cleaning the sensor. If the problem persists, a dead battery or a power interruption may be to blame.

The most common cause of a dirty thermostat is dust. Even a small amount of dust on a thermostat’s surface can cause it to malfunction by interfering with electrical or mechanical components. To clean your thermostat, shut off the power to it, remove the cover and use a can of compressed air or a soft artist brush to clear out any accumulated grime. If the thermostat controls a heating system as well, toggle the temperature selector toward higher temperatures until the contacts close and then use a dollar bill or other thin piece of paper to slip between the contact points, moving it gently back and forth. If the thermostat is a battery-operated model, replace the battery and flip the power back on.

Occasionally, your thermostat can become stuck in its current position. If this is the case, it’s very easy to correct by placing a carpenter’s level on or next to the thermostat and adjusting it so that it sits completely level with the wall.

Occasionally, the heat anticipator on a non-digital thermostat can also become stuck. This is a small metal arm that’s located on the thermostat’s face, sitting on a circular dial. The anticipator is easy to identify by its name, and you can usually feel or hear it moving when a vent opens in your home. To free the anticipator, pull off the thermostat’s cover, locate the little metal arm and push it in or out gently until it moves freely. Lastly, a thermostat that has been positioned directly in the sunlight or near other appliances can generate hotter readings and interfere with its functionality.
