Huston Heating Repair: How to Fix a Faulty Furnace Blower

Wednesday, January 4th, 2012

The blower fan on your furnace is designed to distribute warm air through the ductwork in your Huston home evenly, ensuring you use all of the energy consumed by your furnace. If the blower doesn’t turn on when the furnace turns on or it continues to run when the furnace is off, it can cost you money and result in cold rooms. Here are some tips on how to fix a faulty furnace blower.

What is the Problem?

First, check to see what the problem is. If your furnace blower remains on all of the time, it may be a thermostat issue. Make sure the fan isn’t set to stay on continuously (a common setting for most air handlers). You should also check the limit control switch to make sure it is working properly. If this is broken, it needs to be replaced which is a relatively simple fix.

If the furnace blower isn’t turning on at all, you may have a belt problem. This can be fixed by you if you have the proper tools. To repair the belt problem, first turn off all electricity to the device. You’ll need to remove the old furnace blower belt, so release the tension in the pulleys before removing the belt.

Installing a new belt is not unlike doing so for your car. Make sure to check the blower or your user manual for proper tension when you install the new belt. Make sure you purchase the right size belt and set it to the right tension. If you cannot or you do not feel comfortable doing so, you should call a professional to inspect and repair the problem for you.

Getting the Blower Back Up and Running

Once your new belt is in place, test the system carefully, starting with the lowest setting (if there are variable settings). If it does not yet work or if something sounds strange, call a Huston technician right away. You don’t want the motor to burn out or something else more substantial to go wrong with your furnace or air handler during the middle of the winter.

Warning Signs of a Broken Furnace: A Guide from a Melba Heating Contractor

Friday, December 2nd, 2011

How do you know when your Melba home’s furnace is “on the fritz?” There are warning signs of a broken furnace and some are recognizable – but not all. A broken furnace not only deprives your home of heat and comfort, it also can be deadly, too.

Let’s look at some of the warning signs.

Each year, hundreds of people die and many more are injured from the most common household poison: carbon monoxide. This colorless and odorless poisonous gas comes from several sources and the furnace is the most common source of all; more precisely a broken or malfunctioning furnace. Carbon monoxide is a result of incomplete combustion of a fossil fuel, which is when a fuel does not burn correctly or completely. In a furnace, carbon monoxide gas comes from a poorly operating burner or a cracked heat exchanger. A properly tuned and maintained furnace greatly reduces the risk of carbon monoxide poisoning.

Since carbon monoxide gas is colorless and odorless, it can go undetected. It can make people sleepy and create flu-like symptoms. Sometimes a person may fall asleep and never wake up. But there are warning signs. Drowsiness, vomiting, or flu-like symptoms are a warning sign. Regularly scheduled maintenance of your furnace by a qualified heating and cooling professional and installation of carbon monoxide detectors can reduce the risk of falling ill to carbon monoxide gas.

Another warning sign is a higher energy bill. Sometimes you can’t detect a problem right away because, like carbon monoxide, there may be no obvious signs. Higher utility bills can be a sure sign of a furnace that is working too hard and running more than usual. This may be a result of clogged or dirty air vents, or dirty filters. If your monthly bills are higher than those of the previous year, it may not just be because gas prices are higher.

There are other warning signs of a broken furnace, too. The most obvious is the failure of your furnace to bring your home up to the desired thermostat settings or to maintain an even temperature. Cold or uncomfortable houses are sure signs of a broken furnace. The furnace may cycle on or off, causing an uneven or inconsistent flow of heated air. This can be because of a poor blower or a clogged furnace filter. If you don’t feel any moving heated air or detect any unusual odors or smells coming from your heating vents, that’s a sure sign of a broken or malfunctioning furnace.

A broken or cracked gas line can emit odors and can cause a furnace to malfunction, too.

Don’t take a chance of losing heat and comfort this winter. At the first possible warning sign, call your local heating professional for a heating system tune-up.

What to Do if Your Heating System Breaks in Harris Ranch

Wednesday, November 30th, 2011

What if the heart of your Harris Ranch home’s heating system – the furnace – stops working? The warm air that used to flow from your vents has been replaced by a chilly draft. It isn’t time to panic, but it is time to take action. Before you do anything, determine why the furnace stopped working. It may be something as simple as a tripped circuit breaker in your electrical panel. Check the circuit breakers first.

The pilot light in your furnace may have blown out. It can be re-lit if you follow the directions in your furnace owner’s manual. You can find answers on how to re-light a pilot light on the Internet, too.

If the shutdown has not been caused by an electrical or pilot light failure, there is still no need to panic. But another obvious question is: did you pay your last gas bill? Maybe you had a shutoff notice and either ignored it or forgot about it.

Now that you are convinced that the furnace has pooped out, here are some things you should do. First, find the name of a qualified heating and cooling professional. If you already use a heating contractor, contact them and schedule a service call.

While you are waiting for help to arrive, ensure that everyone is safe and accounted for. Make sure pets are nearby and protected from the cold, too. What you don’t want to do is use any appliance to keep you warm that is not designed to keep you warm, like a stove. If you have electric space heaters or propane heaters, carefully locate them in a well vented room (windows open a bit or portable fans circulating air). You don’t want any build-up of gases from fossil burning appliances, gases which could contain deadly carbon monoxide.

Huddle up everyone into a room and break out lots of blankets. You may even want to make an “adventure” of this – find a movie to watch and pop up a bunch of popcorn.  If your waiting time is more than 24 hours, you might want to call up a friend or relative and make arrangements to spend the night with them.

The main thing to remember is not to panic. Most qualified heating contractors, knowing the circumstances, will send out a repair person in a matter of minutes or within one or two hours. Just remember to avoid keeping warm by using unvented heating devices.

Furnace Safety: A Guide from Warm Springs

Friday, November 18th, 2011

There are many advantages to a properly operating furnace, and the most important ones are the safety and comfort of your Warm Springs home’s occupants. There are several things you can do to ensure the safe operation of your furnace.

Here is a checklist of ideas:

  • Clean or change furnace filters on a regular basis. Replace disposable filters and clean permanent filters using water or cleaning solutions. Your owner’s manual or a qualified heating contractor can suggest a regular maintenance schedule.
  • Check the exhaust vent from the furnace. Clear obstructions such as leaves, clothing, or animal nests from the vent pipe or chimney. Keep roof exhaust vents clear of snow. If there is a faulty exhaust system (like a blocked flue), of if there are cracks and leaks in the pipes or improper adjustment of the burner, or if there is lower air pressure indoors than outside, the furnace can create serious indoor air pollution.
  • A clear air intake is important too, since furnaces need fresh air to “breathe” and complete the fuel burning cycle. Again, check for debris, snow, or animal nests in intake pipes.
  • If you have an older gas furnace, you may want to install a supplementary induced-draft fan that reduces the possibility of backdrafting. Some furnaces have automatic shutoff devices that turn off the furnace if it begins to backdraft.
  • Check internal components such as the blower motor and vacuum any dirt. Check belts and pulleys for excessive wear. You should consult your owner’s manual for any suggested maintenance tips on internal working components.
  • You may also want to check the pilot light to see if it is working and if it producing an even, blue flame. If the flame is uneven, it may be a sign of incomplete gas combustion, which can result in the creation of dangerous carbon monoxide gas.
  • Ensure that your thermostat is operating correctly by raising or lowering the temperature settings to make sure the furnace cycles on and off.
  • Install and maintain battery or hard-wired smoke and carbon monoxide detectors.

Externally vented natural gas furnaces, when properly designed and installed, will operate safely for years. But if you detect a problem, use the most common solution – contact a qualified heating professional to check out your furnace.

Common Furnace Problems: A Guide from Boise

Monday, November 7th, 2011

When it comes to the furnace in your Boise home, you simply want it to work all of the time. But just like any other piece of equipment, your furnace will have problems from time to time. A few of these are relatively simple to fix on your own, but for the most part you’ll need to call in someone to take care of the repairs for you.

However, before you can do that, you’ll need to recognize that a problem exists at all. And the earlier you notice the warning signs, the better off you’ll be. It’s always better to get a furnace problem taken care of right away than to wait until your furnace stops working completely.

It’s also good to remember that quite often the problems you’re having with your furnace are really originating with your thermostat. This is usually welcome news, as thermostats are much cheaper and easier to repair and replace than many other parts of your furnace. In fact, even if your furnace isn’t working at all, it may only be the result of a faulty thermostat.

Another problem you may start to notice is that one part of your house is being warmed more than another part. When this happens, it can be a sign that there is something wrong with the furnace, but it may also be that the pressure in your duct system is not balanced properly. A simple rebalancing of this system can have your house heating evenly again in no time.

You may also realize that your furnace seems to be cycling on and off too often. When a furnace is working properly, it will come on for a considerable period of time and then shut off until the temperature in the house drops below the desired level. However, some problems can cause your furnace to complete many short cycles rather than fewer short ones.

If this is happening to your furnace, there are several possible causes. Something might be wrong with the blower on the furnace or the thermostat might not be feeding the furnace the correct information. Another possibility is that your furnace’s air filter is dirty or clogged.

While there are sometimes simple and straightforward solutions to these types of common furnace problems, it’s best to call in a professional to have them take a look if you’re not sure where to start searching for a problem. In most cases you’ll need them to come out and make the necessary repairs anyway.

How do I Check a Gas Furnace Draft Pressure Switch? A Question from Dry Creek

Wednesday, November 2nd, 2011

There are many reasons why a furnace stops working and in many cases, a Dry Creek homeowner can perform some simple diagnostics to pinpoint the problem. Finding the problem is one thing – fixing it is another. When in doubt, don’t try it yourself. Call a qualified professional.

But let’s look at one possible problem and solution you may be able to perform yourself – testing the draft pressure switch. The draft pressure switch on a gas furnace allows an electrical current to pass through to ignite the furnace. The pressure switch monitors the draft conditions and won’t allow the furnace’s gas valve to open unless draft is correct.

If the switch is malfunctioning, so too will (or will not) the furnace.

The best way to locate the switch is by consulting with your owner’s manual or by going online and simply typing in the words “gas furnace draft switch.” It is identifiable by its round size and is bolted to the outside of the furnace. It should be nearby the draft inducer motor because the two are connected by a metal tube. The tube may sometimes be the culprit, too. A tube that is blocked with condensation may cause the switch to go bad.

To check for proper function, first turn off power to the furnace, either by shutting down the “on’ switch at the furnace or shutting off the circuit breaker.

Use a volt ohm meter to check if the switch is opening and closing properly. Start by zeroing out the meter’s probes by touching the tips together. Using the dial (could be analog or digital), set the meter to 24 volts. Ground the black probe by attaching it to any metal part of the furnace. Then place the end of the red probe on the metal tube connecting the draft pressure switch to the draft inducer motor.

If the switch is working properly the meter should read at least 24 volts, or very near that. If the reading is short of 24 volts, the switch is not working correctly. At that point you may decide to replace it or call a professional to do the task (recommended).

Always remember that there are many sources which will help you diagnose and repair a problem, especially those available through the Internet. If you search YouTube.com you will find many videos advising you on how to repair certain components. Use all of the resources available to you and keep the phone number of a qualified and professional heating and cooling contractor nearby.
