Possible Causes of Poor Boiler Heating Performance: Some Pointers from Brentwood

Friday, November 11th, 2011

You don’t have to be a rocket scientist or a mechanical engineer to troubleshoot – and possibly diagnose – the problems with your boiler when its heating performance is erratic or non-existent in your Brentwood home.

The good thing about boilers is that they are typically reliable and long-lasting. There aren’t a lot of working parts that can break down and cause problems, compared to other home heating equipment. When problems do arise, they are usually related to the expansion tank or circulating pumps. But a problem can be much simpler – like a tripped circuit breaker.

The most common problems can be noise, no heat, or poor/erratic heating. Before calling a qualified heating and cooling professional, take a moment to see if you can figure out the what’s wrong.

If you have a noisy boiler it might be because of two things – a faulty circulating pump or water trapped in the return lines. If the pump breaks it will make a loud noise when its motor runs. Water can be trapped in the return lines, which may require “re-pitching” the lines to allow for a flow back to the boiler. You may be able to adjust the flow by positioning hangers on the piping but replacing a pump is better left to a professional.

If your boiler is producing no heat, it could be because of something as simple as a circuit breaker being tripped or a fuse being blown. Check your circuit breakers and fuse and reset or replace if necessary. Is your boiler thermostat in the heat mode? It should be but if it isn’t, make the switch. If your boiler has a standing pilot you should check to see if it is lit and if not, re-light it.

Other problems would take a professional to fix. For example, no heat can be traced to low water levels in the boiler. The boiler should always be half-full of water and if it isn’t, it is likely because of leaks or a faulty pressure reducing valve. Don’t try and fix the problem by yourself.

Low water levels may not cause the boiler to lose its heating capabilities, but may cause fluctuations in its heating capacity. Again, it is advisable to call a professional to diagnose and fix the problem. Poor heating can also be traced to mineral deposits in the boiler. Consult your owner’s manual on instructions how to flush out the boiler.

As always, read the owner guide or operating manual for your boiler. You should get some good tips on proper maintenance and troubleshooting. And have the phone number of a qualified professional taped to your boiler – just in case.

Furnace Safety: Some Pointers from Gibsonia

Friday, November 4th, 2011

There are many advantages to a properly operating furnace in your Gibsonia home. The most important are the safety and comfort of a home’s occupants and the cost of running the furnace. 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 “breath” 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.

Furnace Fan Doesn’t Run? Why Is That? What Should You Do? A Guide from Bridgeville

Wednesday, November 2nd, 2011

There are several reasons that a furnace fan might stop working at one point or another. While many of these do require a Bridgeville professional‘s attention, there are probably some things you can check on your own before you go and call in the pros. After all, if you can address the problem on your own, it will at least save you from having to pay a technician to come out.

The first thing to check when your furnace is running but the fan isn’t turning is whether or not the fan is actually switched on. Certain models of furnaces have a separate switch to turn the fan on and off. While there is probably no reason that you would want to turn off the fan by itself, it’s worth taking a look just in case. If that really is the problem, you’ll be up and running and back to dealing with better things in no time.

If that’s not the problem, you might try looking to see if any wires leading to the fan are loose or the fuse is blown. If the fan has no power, of course, it won’t be able to work but the rest of the furnace likely would work just fine as long as it doesn’t run on electricity as well.

Of course, the problem very well may be beyond your power to solve on your own. Don’t despair though. Even though you need to call in a professional, that doesn’t mean that the problem will be expensive to fix. In fact, it may be as simple as replacing your thermostat or the motor for the fan itself.

Just because a fan isn’t working doesn’t mean that you’re going to be paying an arm and a leg to have work done on your furnace. If you can’t easily discover the problem on your own, however, or if you’re not comfortable inspecting this type of equipment at all, you’re generally better off just calling in an expert and letting them do the dirty work for you. Paying for simple furnace fan repairs is definitely preferable to having to pay someone to fix the fan and the stuff you broke yourself while trying to fix the fan on your own.

Is Your Furnace Making too Much Noise? (and Happy Halloween Weekend!)

Friday, October 28th, 2011

Happy Halloween weekend from everyone at Boehmer Heating & Cooling! We hope you have a fantastically spooky time! But don’t be scared of the noises coming from your furnace, here is some information about common causes and solutions.

The old saying that “It is better to be seen than heard” certainly applies to the mechanical equipment in your Pittsburgh home. If you hear a squeaky noise or loud clattering you automatically suspect that something is wrong. And if that noise is coming from your furnace, you better pay attention to it. A noise is an obvious sign of a problem – minor or major – and it could result in mechanical failure that could leave your home cold and uncomfortable – and affect your home’s indoor air quality.

Today’s newer variable-speed furnaces keep a constant airflow through the ventilation system utilizing a low speed fan that consumes small amounts of electricity. Constant airflow brings in fresh air and keeps the room air from becoming stale or stagnant. Because of this constant operation, it is important to ensure the furnace is running at peak efficiency, which also means that it is running quietly.

Here are some common noises, possible reasons, and suggested repairs. As always, if you are in doubt about how to repair your furnace, call a local qualified heating contractor and schedule a service call.

  • Squealing noise – could be a worn out or slipping blower belt. Check for proper tension of the belt or replace the belt if it is worn out or cracked.
  • Squealing noise – could be worn out motor shaft bearings. Lubricate the blower motor at the proper points.
  • Rumbling noise – often caused by a poorly adjusted pilot light when the burners are turned off. Adjust the pilot as necessary.
  • Rumbling noise – often caused by dirty gas burners when the burners are switched on. This problem requires service from a qualified heating technician.
  • Buzzing noise – often caused when a blower motor mounting come loose. Tighten the mounting screws or use shims to fill gaps.
  • Hissing noise – indicates a possible air leak. This problem requires service from a qualified heating technician.
  • Ticking noise – possibly a leaky gas valve. This problem requires service from a qualified heating technician.
  • Rattling noise – could be a dirty fan blade. Wipe the fan blade or clean with degreaser.
  • Rattling, grinding, or whining – could be resistance to airflow that causes the motor to work harder. Check the vents in each room for dirt, debris, or obstructions and clear them.
  • Vibrating noise – may not be the furnace but loose or cracked seams in the ventilation system. Check the ductwork seams and hangers to ensure everything is tight. You may need duct tape or bracket hardware.

The best way to keep your furnace and ventilation system from making noises is to practice preventative maintenance. Have your furnace checked annually by a qualified heating contractor – and enjoy the peace and quiet.

Things to Look for When Buying a Heating System: A Guide from Bridgeville

Monday, October 24th, 2011

If you are in the market for a new or replacement heating system in Bridgeville and don’t know much about heating systems, you are not alone. Many homeowners are in the same boat as you. And many of that number put their trust in their local, professional, and qualified heating and cooling contractor to find the right furnace for their homes.

Before calling for an estimate, there are some things you can do to “prepare” yourself for one of the most important purchase you can make. Here is a checklist of things you should look for when buying a heating system.

Know your energy alternatives. There are lots of options today when it comes to heating your home. Gone are the days when the choices were so cut and dried. Check with your heating and cooling contractor for suggestions.

  1. Know what size your furnace should be. Furnaces are not “one size fits all.” The size of the furnace is determined by its Btu (British thermal unit) rating. For example, a one-story ranch home on a crawl space requires less heating capacity than a two-story colonial with a basement, thus it would require a furnace with a smaller numbered Btu rating. A home with a great deal of heat loss through windows and doors may require various furnace sizes. And don’t forget about insulation. Insulation can affect the furnace size, too. Again, check with your heating and cooling contractor for recommendations.
  2. How much room do you need for your furnace? Some homes have mechanical rooms for furnaces and water heaters while others utilize attics, basements, or crawlspaces for furnaces. If you think you need a big furnace to heat a big home, think again. Furnace manufacturers have been downsizing their heating equipment for years, while maintaining the same heating capacities. One example are wall hung boilers, which utilize water and electric as heating sources and are installed on a wall, making the unit easy to locate and easy to service – while at the same time being off the floor and out of the way.
  3. Will your heating system be “plug and play?” New furnaces can take the place of the ones they are replacing by using the same space. But sometimes a replacement unit may need some altering to fit into an existing duct system. It is almost a given that a new plenum (the part attaching the furnace to the ductwork) will have to be fabricated. But the new furnace may also require some other modifications to an existing duct system. You should understand this ahead of time and be prepared to pay additional costs.
  4. A box is a box is a box. As a rule, most heating systems are made the same. In some cases, one furnace manufacturer may produce several different brand names. The best “brand” is the heating and cooling contractor who installs and services your heating equipment. Do your homework ahead of time and find a qualified and professional contractor. Ask friends and family for recommendations. This is may be the most important thing to look for when buying a heating system

Maintenance Tip from McCandless: Why You Should Have Your Furnace Serviced Every Heating Season

Monday, October 17th, 2011

Particularly if you’ve just purchased a new furnace in McCandless, it’s probably not something you think about all that much. As long as it works when you need it to, that is. Unfortunately you usually find out that something is wrong with your furnace just when you need it most. However, there is a way to avoid that kind of problem, and many others, and that’s to have regular maintenance service performed on your furnace by a home heating professional every year.

One of the main reasons to have your furnace serviced is that it allows technicians to catch small problems before they become large ones. During a typical maintenance visit, a technician will examine all parts of your furnace to ensure that they are still in good working order. He’ll also thoroughly clean out the unit to make sure there are no buildups of debris that could cause problems or impede the furnace’s energy efficiency.

And if they do find something wrong like a part that’s beginning to wear out or something that just isn’t working properly, the technician can make the necessary repairs right away. You can get the problem taken care of ahead of time and you won’t have to worry about going without heat during the coldest part of the winter.

That’s not the only reason that annual maintenance is important and beneficial, however. It can also help you save money, both on your monthly energy bills and in the long term. That’s because annual maintenance tune ups keep your furnace functioning at peak efficiency levels longer than they would be able to otherwise.

A typical furnace will lose a small percentage of its energy efficiency every year, and while it won’t seem like a lot at first, that can really add up over the course of a couple of years. With regular maintenance, though, you can often maintain up to 95% of your furnace’s original efficiency for the life of the furnace.

Plus, when the proper maintenance and service is performed on a regular basis, your furnace will simply last longer.

It’s Time for a New Furnace: Some Advice from Finleyville

Friday, October 14th, 2011

Replacing your furnace in your Finleyville home is probably not something you want to think about. After all, a new furnace is a big investment and not something you probably have too much experience with. And sometimes having your current system fixed or tuned up is all you need to get your home heating situation back on track. But there are certain situations in which it makes more sense to just go ahead and get a new furnace rather than simply patching up the old one.

For instance, if you have to call for either minor or major repairs to your furnace on a regular basis, it’s probably time to consider investing in a replacement. All of those repairs cost money and chances are that the furnace you’re paying repeatedly to replace isn’t going to last that much longer anyway.

Rather than continuing to dump money into a furnace that just isn’t cutting it anymore, you’ll be better off making the investment in a new unit. The truth is, you’re going to have to do it sooner or later and by buying a new furnace now, you’re actually saving all of the money you would have spent on repairing the old one for another year or so.

Also, a furnace that requires such frequent repairs is probably not functioning all that efficiently either. When you replace it with a newer model, you won’t just save money on repairs. You’ll also likely notice a considerable savings on your monthly energy bills because of how much more efficient your new model is.

Even if you haven’t been repairing your furnace often, you may be able to notice some signs that the old unit isn’t quite up to the task anymore. If you’re suddenly having some significant humidity problems in your house or if your home isn’t being heated evenly, there’s a good chance your furnace is on its way out.

And, in fact, even if your furnace is functioning just fine but is more than 10 years old or so, it’s very likely you’d benefit by replacing it. That’s because the newer furnaces available now are so much more energy efficient than their predecessors that the savings you’ll incur monthly will quickly make up for the initial installation investment.

Of course, you don’t want to get rid of a good furnace if you don’t have to. But if your furnace is getting close to the end of its expected lifespan, you may very well benefit by putting out the money for a new one now so you can start saving right away on your monthly energy bills.

What Is Forced Air Heating? A Question from Bridgeville

Monday, October 10th, 2011

Chances are that you’ve heard the term forced air heating before in Bridgeville, particularly if you’re in the market for a new home heating system. But what does that actually mean? The truth is that if you’re asking this question, you’re not alone. There are so many types of home heating systems out there that it’s common to be a bit confused and overwhelmed by it all.

The truth is that a forced air heating system is simply a heating system that distributes heat throughout your house using air to carry it. In this type of system, heated air travels through a system of ducts and is expelled through vents into the different rooms and areas of your home in order to maintain a particular temperature. That temperature, of course, is whatever you set your thermostat to, and when the desired temperature is reached, the heat will shut off until the temperature drops down again.

The main difference between the different types of forced air heating systems is the type of equipment that heats the air. For instance, you could have a gas furnace, or a heat pump. All of these are capable of heating air, and when paired with a fan, blower or air handler, can distribute heated air throughout your home.

Many forced air heating systems are remarkably energy efficient and can effectively keep you home comfortable all winter long. Additionally, they are generally made to be incorporated with central air conditioning systems for year round temperature control. Heat pumps are especially convenient in this way, as they’re able to both heat and cool your home depending on the season and your home comfort needs.

Particularly if you already have ductwork in place or if you’re choosing a heating system for a new construction home, it can make a lot of sense to opt for some type of forced air heating. However, if you’re looking to replace an existing heating system in a house that doesn’t already have ductwork in place, the need to put it in can add a lot to the overall installation costs of the system.

Common Furnace Problems: Some Pointers From Cranberry

Wednesday, October 5th, 2011

When it comes to the furnace in your Cranberry house, 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.
