Causes of Reduced Cooling Power in Your AC

Friday, June 27th, 2014

People flock to Anaheim from all around the world for the summer season, where we enjoy warm weather that manages not to edge into the extremes of Los Vegas, Phoenix, or Santa Fe. However, it can still get hot, and if you have an air conditioner that begins to show signs of wavering in its steadfast task of keeping your home cool, you need to call for professional repairs immediately before you lose your valuable cool air.

There are a number of reasons that your air conditioner can start losing its cooling ability. Our staff at Command A/C is familiar with all these causes of reduced conditioning power and they know how to fix them. For all your needs for AC repair in Anaheim, CA, count on our outstanding service.

Here’s Why You Might Be Losing Cooling Power from Your Air Conditioning System

  • Clogged air filter: This is the #1 reason that ACs can start to struggle, and fortunately it is easily preventable. The air filter is designed to protect the interior of your air conditioner’s evaporator cabinet from contamination that enters through the return vents. The filter traps debris and allows the air to pass through. Over the span of a month, the debris trapped in the filter will build up to the point that it will choke off airflow. Reduced airflow means reduced cooling power. Change the air filter once a month during the summer and whenever else you use your air conditioner on a regular basis. If your cooling does not recover after changing the filter, call for repairs.
  • Loss of refrigerant charge: The refrigerant that cycles through an air conditioner remains at a set level known as its “charge.” Refrigerant does not dissipate or get used up during normal operation; however, leaks can cause the charge to drop, and when that happens the system will struggle to absorb the same level of heat that it once did. A decrease in refrigerant charge will also cause damage to the compressor, which can overheat, so call for repairs immediately that will seal the leaks and recharge the refrigerant to its proper level.
  • Impaired outdoor fan: The exterior fan plays an important part in the heat exchange cycle that cools down a home. It draws warm outdoor air across the hot refrigerant in the condenser coil, which allows the condenser to release heat to the outdoors, and then the fan vents away the heat. Should the fan malfunction (due to damage, broken motor, broken fan belt), the refrigerant will not release sufficient heat and then will be unable to absorb as much heat from the indoors. You should always leave the job of repairing the fan to professionals.

Repairs That Will Make Your AC Run More Efficiently This Summer

Thursday, June 19th, 2014

Repairs obviously make your air conditioner run again, but they can also make your system run more efficiently, particularly if you can repair a problem in the early stages. Having your air conditioner run more efficiently, especially in summer, can make repairing your air conditioning system an important part of saving money.

Here are a few of the more common repairs our Command A/C professionals do that have helped our customers save money for the short- and long-term:

Refrigerant Leaks

Refrigerant leaks can be hard to detect; in fact, if they are small enough, they may not even be discernable to an untrained person. Not repairing a refrigerant leak means your system is operating with less refrigerant than it needs, which will put stress on it. Unfortunately, you can almost always count on refrigerant leaks to increase in size, so it’s best to have a technician find and repair them as soon as possible.

Fan Issues

There are two fans in your air conditioner. They are both responsible for air flow and helping with heat release and cooling, so if one starts to malfunction, these two processes get affected. Different problems can happen with your fans, ranging from motor issues to bent fan blades, but all fan problems should be addressed as soon as possible. Bent or loose fan blades tend to make a banging, clunking or bumping sound, and motor issues become evident with symptoms like a decrease in air flow or warm air blowing. Fans repairs are not DIY projects, as they involve a lot of small parts and electrical components, so it’s best to call a trained technician to repair them.

Repairs Can Mean Better Efficiency

Energy efficiency means less energy is being used, a savings you’ll see in your monthly utility bills. Getting repairs done before the problem/s can evolve into bigger issues will not only save you money and time, they will get your AC running more efficiently faster.

Your AC Needs Repairs: Is It the Thermostat?

Monday, June 16th, 2014

One of the reasons you should always leave air conditioning repair jobs to licensed and trained professionals is that often it’s difficult to tell exactly what in an AC system has failed and requires fixing. Central air conditioners are complex devices that consist of multiple systems working together, and failure in one of them can affect the others. Your home’s air conditioner consists of the condenser, the evaporator and air handler, the ventilation, and the thermostat.

It’s the last of these that concerns us here. A malfunction in the thermostat can lead to problems elsewhere in the air conditioner that resemble major mechanical or electrical failures. When you call for air conditioning repair in Anaheim, CA because your AC either won’t turn on, won’t turn off, or cannot deliver the expected amount of cooling, one of the first things the technicians will check when they arrive at your house is the thermostat. Sometimes it will only take some rewiring and re-calibration to fix the trouble—although there are times when it’s advisable to replace an old thermostat with a new one.

At Command A/C, we are familiar with the ways that a malfunctioning thermostat can cause trouble. When you call us, we will quickly get to the bottom of the problem and restore your cooling.

Thermostat Issues That Will Affect the Entire AC

The most common trouble that afflicts thermostats is temperature reading miscalibrations. When the sensors in the thermostat start picking up readings either above or below the actual temperature, it will result in the air conditioner turning on and off at incorrect times. This will lead to energy waste and discomfort. Fortunately, this is a simple fix for AC technicians. If you have an older manual model thermostat, you may consider updating to a more precise digital model.

Wiring failures are another frequent issue with thermostats. Most thermostats use a set of five wires to communicate with the air conditioner, and each wire takes care of a single task. Losing a wire connection can result in AC fans and a compressor that won’t start or stop. These often resemble problems within the air conditioner, but will only require the technicians to fix the wiring problems in the thermostat.

Perhaps the biggest problem that a thermostat can have is poor placement within a house. If a thermostat is located in a spot where it encounters direct sunlight, exposure to drafts, or is placed too far from the center of the house, it will pick up “ghost readings,” false temperature recordings that will lead to erratic AC behavior and uneven temperatures. Usually, the thermostat will need to be moved to a better location to fix the problem.

Although thermostat repairs are frequently easier than other major issues with an AC, the malfunctions will cause larger problems to develop if left without attention. Whenever you sense that you need air conditioning repair service in Anaheim, CA, do not hesitate: call Command A/C right away.

3 Benefits of Packaged Units in Orange County

Monday, June 9th, 2014

*Command A/C no longer services packaged units. For a full list of our air conditioning services, look here!

The most common type of air conditioning system found in homes is the “split” system, which has two cabinets: the outdoor condenser, which houses the condenser coil, fan, and compressor; and the indoor evaporator, which houses the evaporator coil and blower fan. The two units connect through power and refrigerant lines.

A split system isn’t your only option for air conditioning in Orange County, however. At Command A/C we offer installation of packaged AC units. What are “packaged air conditioning units”? They are similar to the rooftop units that businesses use for cooling and heating. All the important components are housed in a single cabinet: condenser, evaporator, compressor, fans.

Here are a few of the reasons that a packaged unit might be the right choice for your home:

Convenience

Packaged units are much easier to service for HVAC professionals than split systems. It’s a quicker job to open the cabinet and diagnose problems when all the components are housed in one place, and there are far fewer refrigerant and power lines to worry about. The fast and efficient repair jobs will cost you less.

Save Space

A packaged unit takes up very little space inside your home, unlike the large cabinets needed for the evaporator. You’ll have valuable indoor real-estate freed up with a packaged air conditioner. Connected to the space-saving is the generally improved appearance of your home’s interior without the need for a piece of industrial machinery tucked away in a corner.

Quieter Operation

With all the fans, motors, and other moving parts placed outside your home, you will have reduced noise pollution indoors. Packaged units are among the least obtrusive systems you can install.

Heat Pump Options

Packaged units can also be installed as heat pumps, so not only will you have all the components gathered in one convenient place, but the single unit will take care of your cooling ­and heating needs.

This may sound like packaged units are the only choice for air conditioning an Orange County home. But there are some possible drawbacks, and the layout of your home may not make these systems practical for you. The best way to find out if you’re a fit for a package system is to call on expert installers today and arrange an appointment. If a packaged unit isn’t the ideal choice, the professionals will steer you toward other superb options.

The place to call is Command A/C: we have the years of experience and training, as well as the selection of top-brand models, to help you receive the best installation possible.
