What to Look for in a Heating Services Company

Friday, January 23rd, 2015

Even here in sunny Orange County, we require the services of a heating professional from time to time. Whether you need to see a technician for annual heating system maintenance, a sudden repair need, or a replacement unit, the continued performance of your heating system is vital for those days when the chill of winter catches you off guard. Feel confident that you’ve found a quality contractor for heating services in Orange County by looking for the following features.

Positive Reviews

These days, you don’t have to look far to find reviews of nearly any company with which you plan to conduct business. Popular social review sites throughout the web contain search engines that make it easy to discover the qualities of a contractor that past or returning customers found most helpful or most unappealing. Some heating contractors also link to or post reviews directly onto their own websites.

Variety of Services

You should also search for a heating contractor who provides a variety of services from which to choose. If you’re in the market for a new heating system, for example, you would probably prefer a technician presented you with several options instead of continuously pushing a single type, model, or brand of system. You’ll want to choose a technician with experience working with your particular type of heating system for repairs as well. And you may even decide to look for a contractor that offers additional upgrades like zone control systems and thermostat upgrades. Look through your contractor’s website to see what services they offer and to make sure they’re someone you can return to again and again.

An Annual Maintenance Program

One of the most important services to schedule year after year, regardless of the outside temperature, is heating maintenance. Your heating system goes unused much of the year, which means parts can become dirty or can fall into poor condition without giving you much warning. If you schedule maintenance before each heating and cooling season, the parts of your HVAC system are cleaned and adjusted so that everything can keep running as new. And when your contractor offers a maintenance program, you’ll often get special offers and discounts on top of your twice yearly visits.

The professionals at Command A/C offer a full maintenance program which includes a 20% discount on services as well as other valuable perks. Call us today for any air conditioning or heating services in Orange County.

Common Problems with Electronic Ignition

Wednesday, January 14th, 2015

Advances in the heating industry have benefited just about every aspect of heating, including the ignition process. The former standard of ignition was the standing pilot light; standing pilot lights require a constant flow of natural gas, which can be quite wasteful. The advent of electronic ignition eliminated the standing pilot, so while there are many furnaces with standing pilots, furnaces are no longer manufactured with them. Electronic ignition is easier and less wasteful, but these components can develop problems just as any other can. Ignition problems should always be handled by trained and certified experts, so if you are experiencing ignition problems, call Command A/C today and have your furnace repaired by professional in Orange County.

Two Types of Electronic Ignition

There are two types of electronic ignition: intermittent pilot and hot surface ignition. With an intermittent pilot ignition, a small, dedicated pilot gas line opens when your thermostat calls for heat. An electronic device creates a spark that lights the gas, ignition the pilot light. One of the more common problems with an intermittent pilot is electronic problems: if the device can’t create a spark, the gas can’t be lit. A secondary problem occurs when there is dirt or dust in the nozzle. A dirty nozzle can inhibit the flow of gas, which can result in a shutdown of the ignition process.

Hot surface igniters work a little differently. Hot surface igniters are probes that heat to a very hot temperature using electricity. When the surface of the igniter reaches the right temperature, the main gas valve opens and ignites the burner. One of the most common problems that develops with a hot surface igniter is cracking. Because the probe is constantly expanding and contracting due to the temperatures to which it’s exposed, the casing is prone to cracking. A second common problem has to do with positioning. If the igniter isn’t close enough to the gas, it won’t be able to light it.

What Is a Packaged Unit?

Friday, August 22nd, 2014

Many homeowners are familiar with split-system air conditioners, systems in which both an indoor and an outdoor unit are needed to cool the air. The indoor air handler contains the components which remove heat from the air. The outside components help heat to release into the air. A different kind of system is the packaged unit, a type of air conditioner used in both residential applications and on many larger commercial properties. A packaged unit contains all of the same components of a standard system. In fact, the only difference between a packaged unit and a standard AC system is that a packaged unit combines all of the parts into one cabinet so that an indoor unit is not necessary.

In traditional air conditioning systems, refrigerant cycles through the indoor and outdoor portions, undergoing several phase changes which allow for the heat exchange process to occur. First, refrigerant enters the outdoor compressor unit, compressing into a high-pressure gas. This allows it to move to the condenser coil, where it changes into a liquid, giving off heat in the process. Indoors, the expansion valve helps to lower the pressure of the liquid before it moves into the evaporator coil. This coil allows refrigerant to evaporate into a gas, absorbing heat from the home. An indoor blower fan helps with the evaporation process and sends cool air through the ducts before the process begins again.

In a packaged unit, all of these parts are in one large cabinet. This cabinet is usually installed outside of the building or on the roof and connects directly to the ducts. This is useful for many reasons. When you need repairs or maintenance, the job may be completed more quickly as a technician can find all of the parts in one area. Additionally, this type of system is beneficial for homes and buildings in which indoor installation is not a possibility, and many homeowners appreciate the aesthetic value of an out-of-the-way rooftop cabinet.

While packaged units may have many advantages, they may not be right for every home. To speak to an expert about air conditioning installation in Orange County, call Command A/C today!

What Is a Packaged AC?

Friday, August 15th, 2014

There may be more options for your new air conditioning system than you realize. Many people are familiar with conventional central air conditioning units. These are split-system units in which one portion of the air conditioner is installed outside while an indoor unit, such as a furnace or air handler, is installed inside. The indoor portion usually connects to the ducts which supply cool air to the home. In this short guide, we focus on a different type of air conditioner, the packaged AC unit, in which all of the parts of a standard air conditioner are combined into one cabinet.

In a conventional central air conditioning system, the indoor unit absorbs heat from the home while the outdoor unit releases it outside. The outdoor unit contains several parts including the compressor and condenser. The compressor adds pressure to the refrigerant so it can make its way to the condenser, where it turns into a liquid and gives off heat. Inside, the expansion valve lowers the pressure, and then the condenser turns it back into a gas as it absorbs heat.

Packaged systems combine all of these parts into one unit. A large cabinet holds the fans, compressor, condenser, expansion valve, and evaporator, and connects directly to the ductwork. This unit may be positioned right outside the home, but it is often placed on the roof. This is ideal for many homes in which installing an indoor unit would be inconvenient. A packaged unit may be an efficient, space-saving system for many people.

While many homeowners use packaged AC units, these systems are ideal for businesses as well. Because the cabinet is located on the roof, technicians can repair or maintain a system and keep out of the way of customers and clients. Large packaged systems are also available for commercial installation. Also, many of these units are modular, meaning a technician can adjust the cooling capacity should the needs of the business change.

If you have questions about air conditioning options in Orange County, or if you need maintenance, repairs, or installation, call Command A/C today!

Common Heat Pump Repairs

Friday, August 8th, 2014

The heat pump is one of the most energy-efficient heating and cooling systems available for homeowners in Orange County. If your heat pump has kept you comfortable for multiple cooling and heating seasons, you may be surprised when your system runs into sudden problems. While heat pumps are generally quite effective, they are made up of many components, so they are likely to develop a few issues over time. The HVAC technicians at Command A/C have seen it all, so we’ve put together a list of some common AC repairs for heat pumps in Orange County.

Low Refrigerant

Your system is designed to hold a certain level of refrigerant at all times. Refrigerant cycles through your system, changing from a gas to a liquid to release heat and from a liquid to a gas to absorb heat from the air in your home. If refrigerant is low, your heat pump cannot transfer heat to the outdoors, which means you can’t receive any cool air inside.

Although refrigerant helps heat to release from your home, the refrigerant itself will never dissipate. Low levels indicate either an improper charge during installation or a leak. Leaks may lead to further problems with your heat pump, such as compressor damage, so you should call a professional at the first sign of low refrigerant, such as a hissing sound or limited cooling.

Faulty Reversing Valve

The reversing valve reverses the direction of refrigerant. So, in a heat pump, refrigerant can move heat from the indoors to the outdoors to cool your home, or it can move heat inside to provide heating in the winter. Like any mechanical part, the reversing valve may encounter problems over time and require repairs.

Thermostat Issues

If you notice that your heat pump is stuck in one mode, it may be a problem with the reversing valve. However, you may simply need a new thermostat. A new thermostat may be more accurate than an older model, allowing for more efficiency and better performance.

You should have a professional look at your heat pump at the first sign of a problem to prevent other damages. Call Command A/C for AC repair in Orange County today.

How Does a Mitsubishi Ductless AC Work?

Friday, August 1st, 2014

Ductless air conditioners are a great solution for many homes or rooms in which installing central air conditioning is not a possibility. While many homeowners without ductwork choose to install window or small room air conditioning units, these may be noisy, inefficient, and unable to cool large areas. Mitsubishi ductless AC systems are the best choice for many homeowners due to their high performance and efficiency and their ability to cool multiple rooms with separate thermostats.

How Does Ductless Air Conditioning Work?

With a traditional split-system air conditioner, the outdoor condenser unit connects to a single indoor air handler. The air handler or furnace connects to the return and supply ducts in the home. The return ducts suck in the air from the home while the supply ducts distribute the now-cooled air to the home. With a ductless system, the air handler is mounted directly onto the wall, eliminating the need for ductwork. The air handler both pulls in air from the living space and pushes the air back out after it is cooled. The installation requires only a tiny hole drilled into the wall so that the refrigerant line can run between both units.

Each outdoor unit can usually accommodate up to four indoor air handlers for even cooling throughout the home. Each air handler is also controlled by its own thermostat, or you can control every unit with a master thermostat. This means you can keep the air running in certain areas of the home and save money by shutting it off in other areas.

Is a Mitsubishi Ductless AC Right for Me?

There are many benefits of Mitsubishi ductless AC systems. Ductless air conditioners tend to have a higher SEER (Seasonal Energy Efficiency Ratio) than central air conditioners, which means you may see significant savings every month. Zone control is another appealing feature since your family members can set the temperature in different areas of the home to their own preferences.

However, ductless air conditioning may not be right for every home. The best person to speak with about ductless installation is an air conditioning professional. For Mitsubishi ductless AC installations in Orange County, CA, call Command A/C today!

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:


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.

Causes of Puddles Under Your Air Conditioner

Friday, May 23rd, 2014

You probably do not think of water having much connection to the operation of your air conditioning. It’s not part of the plumbing, nor does it use the flow of water to provide comfortable temperatures the way a boiler does. Yet water is part of how an air conditioner carries out the job of heat exchange: as the indoor evaporator coil absorbs heat from your home, it also causes water vapor in the air to condense across the coil. The dripping sound you periodically hear from the AC is this water moisture dripping down into a pan, where a drain and pump safely remove it.

Under normal circumstances, you won’t need to give this water moisture much consideration. But there are occasions when you might notice water puddling around your AC: this indicates an issue that needs repairs before it can cause expensive damage and lower your comfort. Call for the skilled technicians at Command A/C for the necessary repair in Orange County, CA to stop the water leaking before it becomes worse.

Why are these puddles happening?

You can probably guess at why water leaking into your home is a problem: expensive water damage, pests and vermin, mold and mildew, and increased humidity in your home. The reasons for it to start are varied. Here are the three most common reasons:

  • Clogged drain or drain line: Like any drain, the one in the condensate pan can develop clogs that will slow or stop drainage of the water in the pan. Often algal growth is responsible. Because of how shallow the drip pan is, it will take no time at all for the condensation in it to overflow the pan and enter your home. Water overflow can often trigger a sensor switch that will shut off the air conditioning to prevent more overflow.
  • Detached pan/detached drain: If the pan and the drain become disconnected because the pan is dislodged (something that sometimes occurs because of amateur tampering in the cabinet) or the drain can break off because of corrosion. Water will start to spill out directly—and this is worrisome if you have furnace installed below!
  • Malfunctioning condensate pump: The electrically-powered pump sits further down the drain line, where it collects condensate until it reaches a certain level, and then the pump pushes the water out into the plumbing system. The pump could burn out and need replacement. Kinks in the line or bad connections could also cause it to stop pumping water from the condensate pan.

Since condensate problems can threaten to stop your air conditioning, lower your indoor air quality, and damage your home and furnace, don’t wait to call for help when you see water puddles around the AC.

Schedule Air Conditioning Maintenance Before the Summer Hits

Friday, May 16th, 2014

Those spring temps are pretty fabulous, but after they are gone, we are in the heat of summer here in Orange County. Command A/C knows how uncomfortable it can get, and the last thing we want to see is our customers experiencing a mid-summer air conditioner breakdown. This is why air conditioning maintenance in Orange County is one of our specialties, and why we strongly recommend you do a spring tune-up every year.

Why Do Annual Spring Air Conditioning Maintenance?

Your air conditioner is a complex system of multiple parts and components that all work together to cool your property. If you haven’t used your system in a while, it is very likely that it has collected leaves, debris and dirt. In addition, if unknown problems began toward the end of last season, they most likely didn’t disappear. Wouldn’t you rather know about these problems on a nice, spring day rather than on a 90 degree day in July?

Here are some reasons why Command A/C recommends scheduling air conditioning maintenance for our Orange County customers:

Maintenance can preserve your A/C’s cooling capability – by testing your air conditioner in the spring via a regular maintenance visit, your air conditioning technician will be able to detect any existing problems that could deter or obstruct the cooling process.

Maintenance can potentially improve your air conditioner’s energy efficiency – lots of small items can interfere with your system’s ability to run efficiently. Typical problems are dirty air filters, refrigerant leaks and reduced air flow. By tackling these problems before summer, you are preparing your system to work optimally when it runs full-time.

Maintenance ensures your air conditioner gets cleaned – cleaning certain components of your air conditioning system is important. Areas that typically need cleaning are the fans, condenser coils, evaporator coils and the fins. Dirt and dust collection can create strain on an air conditioning system, so getting rid of the accumulated layer of dirt can make your system breathe easier.

Maintenance can prevent big repairs – by performing regular maintenance on your AC, your technician is more likely to catch potential problems before they become big problems.

Call Us to Schedule Spring Maintenance for Your Air Conditioner

Spring maintenance can help your system do what it should in the summer: keep you cool and comfortable when it’s hot outside. As we head into the summer, call Command A/C to schedule your spring air conditioning maintenance in Orange County.

The Trouble with Low Refrigerant

Wednesday, September 11th, 2013

Your air conditioning system uses a compressed refrigerant in order to remove heat from your home and exhaust it outside. This refrigerant is one of the key components of your AC and we here at Command A/C wanted to share some of the issues that can arise when your system has low refrigerant. Give us a call if you need any kind of Orange, CA air conditioning repair services.

Orange, CA Air Conditioning Repair: Low Refrigerant

Read on below for some of the common problems that can result from low refrigerant in your AC.

  • Not enough cooling – In order for your air conditioning system to effectively remove heat from your home, it needs to use a compressed refrigerant. This refrigerant is similar to Freon, but in newer models they use an environmentally friendly type. The refrigerant is actually the vehicle that carries the heat away from your home, so if there isn’t enough of it then you won’t get enough cooling in your home.
  • Noises – If there is low refrigerant in your air conditioning system, then you may start to notice a gurgling noise coming from it. This is the sound of air bubbles moving through the system.
  • Inefficiency – Without the proper level of refrigerant, your system will likely have to work harder to cool your home which will reduce its efficiency.
  • Ice on the coils – Your AC has a large fan that pulls in warm air from your home and passes it over a series of very cold coils (evaporator coils) which contain the refrigerant. Under normal operating conditions, condensation will form on the coils, similar to how condensation forms on a cold glass on a hot day, and drip into a drain. But with low refrigerant, this condensation will actually freeze and restrict the flow of air through the coils and, thus, into your home.

If you’re having any problems with your air conditioning system or if you suspect that you have low refrigerant, call the Orange, CA air conditioning repair professionals at Command A/C today.
