Common Problems with Furnace Burners

Friday, October 31st, 2014

The burner in your furnace is where air and gas meet and combust. It is a critical part of your furnace, and problems with it can result in heat loss. Repairing a burner takes training and expertise, so working on your burner yourself is not recommended. The best way to ensure that your heating, works the way it’s supposed to is to call the professionals at Command A/C. Our certified and trained technicians are available in Cypress, CA 24/7, so if you are experiencing issues with your furnace, call us today.

What Is the Burner?

The burner is the part of your furnace through which the natural gas flows and ignites into jets that heat the air for your home. The burner is a rectangular-shaped component with 4-8 short metal tubes that are fed the gas from the furnace’s manifold. An igniter at the right side of the burner ignites the gas jets, and a flame sensor at the other end monitors the flames. The burner heats the heat exchanger, which provides the warm air for your home.

Common Problems with Burners

Here are some common problems that can develop with a burner:

  • Rust/corrosion – any kind of rust or corrosion on your burner means that the burner needs to be replaced. A rusty burner can leak gas and/or malfunction, leading to problems with heating.
  • Problems with the igniter – there are two types of igniters: intermittent pilot and hot surface igniters. While each works differently, they both do the same thing: ignite the gas in your furnace. When the igniter is dirty, has a crack, or there is no spark, the burners won’t light.
  • Problems with the manifold – the burners are fed the gas via a manifold. The manifold is a pipe that runs the length of the burner, with small nozzles feeding gas into the burner tubes. If something obstructs the manifold from the inside, or the manifold is bent, problems can ensue with the burner, in addition to potential problems with safety.

Without a properly working burner, you may lose heating in your home. Repairing a burner is not a DIY kind of job, so call Command A/C and let one of our certified technicians handle any heating repairs in Cypress, CA.

Why Is Fall Maintenance Important?

Friday, October 24th, 2014

We have warm daytime temperatures, but our nights are getting cool. If you haven’t turned your heating on yet, you will need to soon – is your system ready? One of the best ways to prepare your heating system for cooler temperatures is to schedule fall maintenance. When performed by a trained and certified technician, like the ones from Command A/C, maintenance can provide a number of important benefits. Call us today and schedule your maintenance appointment for this fall.

Benefits of Fall Maintenance

  • Helps prevent repairs – during a maintenance appointment, your system undergoes a thorough inspection. This inspection allows your technician to discover any existing or developing problems. If the problems are minor, such as frayed wiring or a worn fan belt, these items will be repaired. Larger problems will be reported to you so that you can schedule a repair appointment. Repairing small problems and taking care of larger ones helps get you ahead of repairs on your system and can prevent new issues from developing.
  • Better energy efficiency – your heating system was made to operate at a certain energy efficiency level. When it is worn, or covered in dust and dirt, it won’t be able to perform at the efficiency level it should. During maintenance, your system’s components are cleaned, adjusted and lubricated, allowing them work optimally; this helps your system retain its energy efficiency.
  • Extends life of equipment – dirt, dust and wear and tear act as a drag on your system, causing stress. When your system operates for a long period of time under stress, it can cause premature aging. Maintenance helps your system run optimally, so it doesn’t operate in a stressed state. This helps reduce the effects of aging, which can extend the life of your equipment.

Maintenance helps your system maintain its energy efficiency, increase your comfort and helps prevent future repairs. Fall offers the perfect window of time to schedule maintenance for your heating system in Cypress, CA, so call Command A/C today and schedule an appointment with one of our experts.

How Does a Zone Control System Help My Heating?

Friday, October 17th, 2014

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

When you turn on your heating system, you expect to have full control over your indoor comfort. However, sometimes the natural process of heat exchange may get in the way. For homeowners with expansive floor plans, more than one level, or unique home designs, a standard furnace simply cannot distribute heat evenly to the entire home. Zone control can help you keep temperatures under control in any area of the home and keep your family members comfortable throughout the year.

Why You May Need Zone Control

In many homes, a single thermostat controls the temperature in every area. However, in larger homes, this system cannot possibly offer even temperatures. Heat naturally rises, so you may find that the upstairs rooms often feel warmer than downstairs. Or, large windows may make one area of the home feel cooler than the other areas.

Even if the temperatures in your house remain relatively stable, some of your family members may have different temperature preferences than others. If you’re sick of hearing family members argue over the thermostat setting, a zone control system may be the perfect solution.

How it Works

When you call an HVAC company to install your new zone control system, a technician will need access to the ductwork in your home. The technician installs dampers in each area of the ductwork for which you would like zone control. Each damper is connected to its own thermostat but can also be controlled by a master thermostat located in a central area.

When you set the temperature in a particular room or zone, the thermostat controls a damper that opens or closes to adjust the amount of airflow into the room. No longer will you have to deal with uneven temperatures throughout the home. And you won’t hear family members complain about being too cold or too hot in their own rooms. You can also use zone control to save a little money. If no one uses one area of the home throughout the day, shut off the heat in that zone only to save on your energy bills. When you decide to ask a professional about installing a zone control system in Cypress, CA, call Command A/C today!

What is an Upflow Furnace?

Friday, October 10th, 2014

There are a number of characteristics that homeowners use when selecting a home heating system. Size, fuel type, and AFUE rating are all common factors in making the right decision. When selecting a furnace, however, something is commonly left out. Do you want an upflow furnace or a downflow furnace? Despite not being as well known as the other differentiating factors, this question has a definite impact on the performance of your furnace. Read on to discover the qualities of an upflow furnace, and whether it’s right for you.

Up and Out

Essentially, what makes a furnace upflow or downflow is where it takes in cold air to be heated. An upflow furnace takes in cold air at the bottom of the unit, heating it and circulating it from the top. There are a couple of implications with this kind of furnace, the first being efficiency. Hot air naturally rises, and sinks when it cools. This makes an upflow furnace more efficient, because it is taking advantage of heat’s natural behavior. This will result in heat being more easily distributed throughout your house, requiring less work from the furnace and lowering your heating bills.

The other implication is the location where the furnace needs to be installed. Because of the way upflow furnaces operate, they tend to be installed in basements. This allows them to waste very little heat, as it all rises into the house through the floor. This is also viewed as a more comfortable method of heating. A downflow furnace heats from the top down, which results in much of the warm air becoming trapped in the ceiling where it isn’t much use.

The disadvantage of an upflow furnace is that it isn’t necessarily viable in all homes. Not all homes have basements, especially those on the west coast. This can make proper installation of an upflow furnace more troublesome, perhaps even impossible.

If you are thinking about installing an upflow furnace, call Command A/C. Our heating experts operate throughout the Cypress, CA area. We will find the right furnace for your living space.

How Does a Ductless System Provide Heat?

Friday, October 3rd, 2014

Ductless heating systems are a fairly new technology that is quickly gaining traction in homes across America. Rather than utilizing ducts, a ductless unit is comprised solely of an outdoor compressor unit and an indoor blower. This allows the ductless system to avoid the 30% of heating efficiency lost to duct leaks that forced air systems experience. Let’s take a look at how ductless heat systems compensate for not having a furnace to rely on.

Ductless Heating

In forced air systems, a furnace is used to heat the air which is then circulated to the rest of the house. A ductless system does not have a heat pump to rely on, so it acts as a heat pump does. Thermal energy is drawn from the surrounding air into the outside unit. From there, it is sent back to the indoor unit, where it is warmed to the desired temperature and released into the house. The use of this thermal energy allows the ductless system to be just as efficient as a forced air system, without needing a furnace to provide heat.

A ductless system has no way of transporting warm air between rooms. If you want to warm every room of your house, you will need multiple units. Fortunately, all units can be linked to one thermostat for convenience. A ductless system is easier to install than more traditional systems, since it does not require that ductwork be installed all over the house.

Of course, there are a couple of considerations before you install a ductless heating system. Because the ductless system relies on outdoor thermal energy, it does not work as efficiently in very cold environments. The lack of thermal energy in the surrounding air forces the heat system to work much harder to reach the target temperature. As long as the condenser unit is kept free of frost, a ductless heater can heat your home just fine. Just don’t expect it to do so as easily as at lower temperatures.

If you are considering installing a ductless heater in your home, call Command A/C. We offer heating services throughout the entire Cypress, CA region.
