3 Furnace Safety Switches That Protect Home and Health

Friday, March 20th, 2015

Some people have concerns over running a gas heater, as any gas installation comes with the risk of overheating, natural gas leaks, and carbon monoxide poisoning. However, today’s furnaces not only burn fuel more efficiently than ever before, they also have advanced safety features that make these safety issues very rare. At Comfort Central, Inc. we want to answer your questions about installing a furnace in Arden, so we’ve put together this guide to some of the key safety features of a modern gas furnace.

  • Flame Sensor: This is the component that is perhaps most important in preventing gas leaks. The flame sensor detects when there is no longer a flame at your burner, and shuts off the gas after a set amount of time. In older furnaces where the pilot light stayed on at all times, this was called a thermocouple. It is simply a probe that sends a signal to the control board if there is nothing present. It is possible for the thermocouple or flame sensor to get a faulty reading, particularly if it is dirty or out of a place. You should leave it up to an expert to determine whether the part is faulty or not.
  • Limit Switch: The limit switch is programmed to switch off the furnace if the furnace plenum is at risk of overheating. Long ago, this would have meant an explosion, but today, limit switches keep this from ever becoming a fear. Some modern limit switches are combined with the fan switch, which is the part that delays the fan a bit until the unit heats up. If the plenum is overheating, it’s most likely because the fan failed to turn on or to power to the extent needed to move heat out of the plenum.
  • Air Pressure Switch: In modern furnaces, an additional blower helps to vent the byproducts of combustion, such as carbon monoxide, away from the home and through the flue. If there is not enough are pressure moving through the flue, a modern unit will shut down as the air pressure switch signals to the control board to do so.

Furnace Problems Due to a Clogged Air Filter

Friday, January 30th, 2015

It is often the smallest and most subtle things that cause the biggest problems, especially when it comes to home heating systems. If not properly maintained, there are a hundred different ways that small parts can cause big problems for your furnace. Let’s take a look at one of the most important, though unassuming, parts of the furnace: the air filter.

What is the Air Filter?

The air filter is a fiber mesh stretched over a frame, and installed in the air return duct of your furnace. It is designed to protect your furnace from any dust and debris that might blow in from the ducts, while still allowing air to travel freely through the system. It does this job remarkably well. However, the air filter does need to be cleaned or replaced every 1-3 months in order to prevent it from becoming clogged with all the particulates that it captures. If this is not done, it can lead to some pretty severe issues with your furnace.

Clogged Air Filter Problems

The biggest problem with a clogged air filter is that it doesn’t allow air to pass through it anymore. This lack of cool air flowing into the furnace does two things. First, it prevents the furnace from actually warming air and circulating it throughout the house. Second, it traps all of that heat that the furnace is producing inside the furnace itself. That trapped heat raises the temperature inside the furnace significantly, which will quickly trip the furnace’s limit switch and shut the system down as a safety measure.

After the furnace temperature has dropped sufficiently, it will start up again in response to the thermostat’s continuing calls for heat. That will trip the limit switch again, which will shut off the furnace again. This constant on/off cycle is called “short-cycling” and severely limits the lifespan of your furnace by putting it under far more strain than it is designed to handle. It can also lead to other issues, like a cracked heat exchanger.

If you haven’t had your air filter cleaned in more than 3 months, call Comfort Central, Inc. We provide quality furnace repair services throughout the Brevard area.

Why Are Newer Furnaces More Efficient Than Older Ones?

Wednesday, January 7th, 2015

When you get a new cellular phone, you may be excited to show your friends and family how much better it works than the older one. Your older phone may have been slow to run, offered very little storage, and had a run-down battery. But the new phone may use a totally different operating system and come equipped with a battery that lasts longer than any you’ve ever seen. When you install a new furnace, especially if your old standing gas pilot model was decades old, you’ll notice immediate energy savings and better performance, and you may even end up bragging to your friends.

Let the technicians at Comfort Central, Inc. help you select a new furnace that runs better and more efficiently than any you’ve had before.

If your furnace is nearing the end of its lifespan, you may have noticed decreased efficiency over time. Sure, your furnace has always cost a lot of money to run, but now that it’s in desperate need of replacement, you’re noticing even higher utilities. This is to be expected, as the components of a furnace tend to wear down over time, which means they become overworked. A brand new furnace will have new parts so that the unit runs in top condition.

In fact, your new furnace will probably run much more efficiently than your old one did even when it was brand new. Older furnaces have an AFUE (annual fuel utilization efficiency) of about 50-60%, meaning they only use about half of the energy they require to run to actually heat up a home. Newer furnaces are required to have an AFUE of over 80%, which means a large majority of the energy utilized goes towards heating the living space.

So what technology brought on this change? For one, newer furnaces have advanced mechanical parts. But also, the new ignition systems used in gas furnaces, chiefly an intermittent pilot and hot surface ignition. With these types of ignition systems, the pilot light does not need to remain lit throughout the day, only when the heating cycle begins. So you don’t have to worry about throwing away natural gas throughout the day.

Are Gas Furnaces Dangerous Options for Residential Heating?

Wednesday, November 19th, 2014

Some homeowners have safety concerns about using a gas furnace. While gas is highly flammable, furnaces are manufactured with multiple safety switches and mechanisms that help ensure you and your home’s safety. As such, gas furnaces are no more dangerous to operate than any other type of furnace. However, if you are concerned about your furnace in Arden, one of the best ways to maintain safety levels is to schedule annual maintenance.

Why Maintenance Helps

There are a few ways in which maintenance helps maintain the safety of your gas furnace:

  • Thorough inspection – your entire system is thoroughly inspected during a maintenance appointment. This allows the technician to detect any existing or developing problems, including things like a cracked heat exchanger or corroding joints in your flue.
  • Testing of system – your system is tested to make sure it is operational and all safety mechanisms work as needed.
  • Cleaning of components – the components in your heating system are cleaned and adjusted, so that dirt and dust can’t build and cause problems. No component functions well with a layer of dirt and dust on it, but certain components, like the heat exchanger, can develop serious problems from a thick layer of dust.

Types of Safety Mechanisms

Here are a couple of examples of the safety mechanisms on your furnace:

  • Flame sensor – the flame sensor in your system is responsible for detecting whether or not a flame is present and if it’s at the temperature it should be. There is a flame sensor in the last jet of your furnace’s burner and a second one if your furnace uses an intermittent pilot for ignition. For ignition, the flame sensor has to detect that the pilot is lit and viable; if it’s not, the flame sensor will not allow the main gas valve to open. If the burner has been lit, but the last burner isn’t firing correctly, the flame sensor will turn off the main gas valve, abruptly halting the heating cycle.
  • Limit switch – the limit switch prevents your furnace from overheating. The switch is set to two temperatures: one that cues it to blow the warm air from the heat exchanger into your home and a second that cues it to shut down the system when the temperature becomes too hot.

These are just two of several safety mechanisms your gas furnace in Arden is equipped with. If you have concerns about your gas furnace or questions about our furnace maintenance service, call Comfort Central, Inc. today and schedule an appointment with one of our experts.

Ways to Save Energy with Your Furnace This Winter

Wednesday, October 22nd, 2014

Energy efficiency is always a priority, especially when it comes to heating. As we head into the heating season, there are a few things that can be done that can help you be more energy efficient this winter. Helping your furnace in Brevard is good for your heating system and your wallet, and most of our suggestions don’t take too much time to implement. Have questions about improving energy efficiency this winter? Call Comfort Central, Inc., and speak to one of our trained experts about the benefits of installing a new furnace for your home in Brevard.

Energy Tips

Here are a few tips that can help you save energy this winter:

  • Conduct an energy audit – energy audits pinpoint exactly where you are losing energy. There are several tests that can be conducted, and you’ll be given a full report of the findings and recommended solutions for any problems that are found.
  • Increase insulation – if your insulation isn’t adequate, consider having more installed. There are several kinds of insulation available, and some are very good for retro-fitting.
  • Install ceiling fans – ceiling fans help circulate the air and can keep heat from rising too high in a room – just make sure the fan is rotating in a clockwise direction.
  • Use a humidifier – humidity holds heat, so adding some extra moisture to the air can help it feel warmer; it’s also good for your skin and health.
  • Use a programmable thermostat – a programmable thermostat allows you to control the amount of heating you use, which can go a long way toward saving energy. With a programmable thermostat, you can turn down heating during the day and have it cycle back up in the evenings for comfort.
  • Let the sun in – daytime heat gain can account for up to 10 more degrees of heat, so if you have shades or drapes, open them during the daytime to allow the sun’s natural heat inside.
  • Follow recommended thermostat settings – recommends that you set your thermostat no higher than 68 degrees when you are at home, and 10-15 lower when your home is unoccupied and at night.

Increasing your energy efficiency can help take some operating stress off of your furnace in Brevard, as well as your wallet. If you have questions about any of the above suggestions, call Comfort Central, Inc., and make an appointment with one of our specialists.

How to Prepare Your Furnace for the Heating Season

Wednesday, September 17th, 2014

If you own a furnace, you need to keep it in top shape to ensure you stay warm throughout the heating season. Your air conditioning system has been running all summer long, so it may seem as though no new problems should have developed with your heating system. However, your furnace may be inefficient due to dirty components or minor problems that could lead to further damages later on. Your best bet is to take care of maintenance tasks now before they become major repair needs. Here are some of the ways you can help get your furnace ready for the heating season.

  • Change the Furnace Filter: One of the best things you can do for your heating system is changing the furnace filter. This should be done about once a month, but the frequency may depend on how often you use your unit. A dirty filter allows dirt and contaminants to move into your ductwork. Furthermore, a clogged filter keeps your furnace from drawing the necessary amount of air into the furnace. This means your motor must work harder and run longer, using more energy and wearing out your unit.
  • Remove Any Obstructions from Vents: The thermostat in your home lets your unit know when to turn on and off. But if household obstructions block the vents, it will take longer to reach the desired temperature, meaning your furnace cannot efficiently heat your home. Be sure that all vents are open and that nothing blocks your vents from drawing in or distributing air.
  • Schedule Maintenance: The most important step you can take towards a more efficient and better performing furnace is by scheduling heating maintenance with an experienced technician. Heating maintenance involves cleaning and inspecting your system, as well as tightening connections, checking the thermostat, and making any adjustments that may be done without major repairs. The technician will let you know whether you need to schedule additional services.

3 Reasons to Consider a Furnace in Hendersonville

Tuesday, January 14th, 2014

There are many different types of heating systems that you can choose for your home. There are furnaces, boilers, heat pumps, and more. If you’re looking to install a new heating system in your home, you want to consider all of the possibilities and take the unit that works best for your circumstances. That said, the traditional gas furnace still offers a lot of advantages that you might benefit from. Here are 3 reasons to consider a furnace in your Hendersonville home.

  • Cost: Gas furnaces cost much less to use on a month to month basis than electric heaters, since natural gas is cheap and plentiful. That lower cost can really come in handy during the coldest days of the year, when the furnace sees increased use.
  • Longevity: Natural gas furnaces tend to last a long time, providing you keep it well-maintained and address repairs promptly. Gas furnaces are comparatively simple systems, and their upkeep can be handled fairly easily by trained professionals. That can translate into a long shelf life, extending the time you can make use of it and deferring the cost of installing a new system.
  • Environmentally friendly: Gas furnaces burn very cleanly, with few emissions, and they also heat very efficiently. That makes them a very “green” form of heating your home.

There are other reasons to consider a furnace in Hendersonville, including ease of use and the ability to use an existing duct system already in place for your air conditioner. Whatever your circumstances, you can find help with the experts at Comfort Central, Inc. Pick up the phone and call us today. You’ll be glad that you did!

3 Reasons Your Furnace is So Expensive to Run

Monday, December 9th, 2013

In Hendersonville, furnaces are often the go-to method of heating your home. They fit our local climate extremely well and can provide excellent heating power when the winter nights get cold. While heating your home is never free, if your heating bills seem very high, there are a few things you can do. Here are 3 reasons your furnace in Hendersonville is so expensive to run, along with ways to cut down on those costs.

  • The furnace has not been maintained. The internal components of the furnace will build up dust and grime over time, which increases friction in moving parts and can interfere with other parts of the heating process as well. In addition, general wear and tear can reduce the efficiency of a furnace, costing you more in monthly energy bills. You can address this issue by scheduling a maintenance visit from a trained technician, preferably in the fall before heating season begins in earnest.
  • Your home isn’t well insulated and sealed. This isn’t just insulation in the walls and attic, but it also means things like cracks under the front door and windows, as well as window panes made of aluminum and other non-insulated materials. These can leach heat out of your home, forcing your furnace to work harder to keep it warm. You can address it by adding insulation – particularly in the attic, since hot air rises – and by using weather stripping to seal the cracks around your doors and windows.
  • Heating when you don’t need to.  If you have times during the day when the house is usually empty, such as when everyone is at work or school, you can turn down the heat during that time (though for people with boilers and heat pumps, we don’t recommend a set back more than 5 degrees). A programmable thermostat can do this automatically, saving your money without any extra effort on your part. A zone control system can allow you to keep different areas of your home at different temperatures, so you don’t have to waste heat keeping the empty guest bedroom at the same temperature as the rest of your home.

For other reasons why your furnace in Hendersonville is so expensive to run, as well as installation and upgrade ideas on making the most out of your furnace, contact the experts at Comfort Central. We handle Hendersonville furnace issues of all varieties, so don’t hesitate to give us a call!
