Air Conditioner Repair – How It Works


While air conditioners can differ from model to model, they all operate on similar principles. In this article we will address how an air conditioner operates, as well as potential problems you may encounter.

When you switch the air conditioner on, the thermostat control sends 120 volts of alternating current to the compressor and the fan motor. The compressor acts as a pump, compressing refrigerant in gas form into the condenser coils located near the back of the unit where the gas is condensed into a hot liquid. The condenser coils dissipate the heat as the liquid travels through them. Once the refrigerant has passed through the condenser coils and the capillary tube, it travels to the evaporator coils located near the front of the unit.

As the refrigerant liquid enters these coils, it expands into a gas which makes the coils cold. The gas flows through the coils to a suction line attached to the compressor. The compressor converts the gas back into a liquid, and the cooling cycle continues.

At the same time the fan motor rotates a blower wheel which draws in air to be cooled by the evaporator coils before re-circulating it back into the room. The same motor also operates the condenser fan blade, which blows outside air through the condenser coils to cool them.

The air temperature is regulated by the thermostat control. Depending on the model, the control may be a thermostat switch and sensing bulb assembly or an electronic control board that works with a sensor. The sensing bulb or electronic sensor is clipped to the front of the evaporator coils to monitor the temperature of the air entering the coils. Once the room has sufficiently cooled, the thermostat control shuts off the voltage to the compressor. Some models which use a vent can operate the fan motor only to draw in air at night. However, when the appliance is actively cooling the air, the vent must be closed for the system to work properly.

Be aware that it’s normal for water to collect in the bottom of the air conditioner when the appliance is running. A slinger ring on the condenser fan blade picks up this water and sprays into the condenser coils to help the coils dissipate the heat. To prevent the water from dripping into the room, the appliance should be tilted back slightly when installed.

If you can hear the appliance running but the air does not appear to be recirculating, the fan motor has likely burned out and will need to be replaced. If the air does not cool at all, the compressor may have failed, or the refrigerant may have leaked out of the system. Be aware that any repairs to the refrigerant system must be performed by a licensed technician.

If you suspect that the air conditioner is not cooling the air properly, you can perform a test using a thermometer. Allow the air conditioner to run for 15 minutes then measure the temperature of the air in the room, and the temperature of the air exiting the cooling duct. The difference in temperature between the room air and the cooled air should be 15 degrees Fahrenheit or more. If the difference is less than 15 degrees Fahrenheit, the air filter may be clogged, or the condenser coils may require cleaning.

A clogged air filter can cause the evaporator coils to frost over and the efficiency to be greatly reduced. Over time the condenser coils collect dirt and debris, so we recommend cleaning the coils periodically by using compressed air to dislodge the debris and a vacuum to clean the inside of the cabinet.

How to Choose the Best Home Appliances

What are the best appliances?

We’re often asked what the best appliances are and it is hard to say.
If you’re in the market for a clean coffee maker, for example, we would have wanted to know more information before picking it. Do you drink a lot of cups of coffee or do you drink just one at a time? Do you like brewed coffee or pressed? As you can see there are a lot of variables to look at when it comes to choosing the best appliance for you.
The number one mistake that we see people making is buying appliances that match their kitchen more so than matching their needs. The best kitchen appliances match the needs of consumers, more than the need of the decorator. Instead of purchasing a nice bright green hand mixer or immersion blender, it might be a good idea to take a look at the functionality of it at first. If it’s not up to par, it shouldn’t be in your kitchen.
The best appliances are ones that come with a warranty’s. They need to be from reputable manufacturers that you know and trust. Companies like Black & Decker, Hamilton Beach, Oster, General Electric, and more. What sets the best kitchen appliances back from the rest is quality. Look for it!
Although most products come with a warranty, you may want to look into renter’s insurance or appliance repair. It’s a good idea if you’re prone to having broken appliances. It’s also a smart choice if you use your kitchen appliances a lot.

Should I pay full price for the best appliance?

Although paying retail isn’t necessarily a bad thing, if you can afford it. It’s always a good idea to look for sales or to price watch at the bare minimum. We often provide good links to websites in order to purchase the best appliances at a discount price. If you’re comfortable waiting, there are always new and updated version of the best appliances coming out so if you wait until you get the newest best appliance, you will be able to maximize the life of your appliance.

Top 3 Solutions for Dryer Airflow Maintenance

How to prevent the inside of your dryer from looking like decay and disaster.

Dryer Repair – Top 3 Solutions for Proper Airflow Maintenance

When a dryer is taking too long to dry your clothes, a lot of the time people think their dryer is going out or the heating element stopped working, but a lot of the time this indicates some sort of airflow issues.
Airflow issues can also cause the safety thermostat to trip or the thermal fuse to blow, and usually when one of these parts go out its related to one of the following three things that I’m going to go over today.
  1. Clean Your Dryer’s Lint Filter on Each Use

The first thing that I want to cover is your dryer’s lint filter. It’s very important to clean your dryer’s lint filter between each and every load of laundry you do.
The lint filter is where the hot and damp air in the dryer needs to pass through before it leaves the dryer, and if the lint filter is blocked up the air can’t get out. When this happens your clothes aren’t going to dry or it will take a really long time for them to dry.
  1. Clean Your Dryer’s Vent Hoses Once a Year

The second thing that I want to cover is your dryer vent hoses. I’d recommend having them cleaned at least once a year. Over time the inside of the vent hoses will start to build up with lint causing the air that passes through the hoses to slow down which causes very poor drying. If the dryer hose venting is longer than 10 feet, I would recommend having them cleaned at least every 6 months or so. Just for the fact that air has to move through such a long hose, the lint gets trapped a lot easier than if the hose was short.
And another thing to check is where the vent hose leaves the house, usually you have some sort of damper or flat or cover screen on the outside of your house. You need to check it every few months because a lot of times animals will build nests on the outside, or lint will build up and that causes restrictions around the end of the vent hose.
  1. Clean the Inside of Your Dryer

And the last thing I want to cover is the dryer itself, this is just as important as the first two items that I covered. If you want to keep your dryer running efficiently, if you cleaned your lint filter between every load, if you keep your vent hose clean, the last thing you want to do is make sure you clean the inside of your dryer.  I’m not talking about where you put your clothes inside the dryer, but the parts that you can’t see inside your dryer. The dryer isn’t exactly airtight so if you have some sort of venting issue the lint’s going to start to accumulate inside the bottom and basically put a layer of lint on top of the components on the inside including your heater, motor, thermostat and it could definitely start a fire. Lint will also build on the rollers, the pulleys, causing the belts to have a lot of friction whenever it’s going around and you’ll be replacing your dryer belts a lot more frequently than you need to.
