Common Boiler Problems

Thursday, February 27th, 2014

Listing “boiler problems” takes a more work than listing “furnace problems” or “heat pump problems.” That’s because boilers experience fewer repair needs and malfunctions than other home comfort system because they do not use as many mechanical parts that can break or wear down. Boilers have remarkable longevity because of this, and with basic maintenance performed once a year by a professional, your boiler should give you at least two decades of excellent heating.

But although there are fewer “boiler problems” to list, they do exist. Here are some troubles with boilers that will require you call for heating repair in Pittsburgh, PA. You can reach Boehmer Heating & Cooling 24 hours a day when you need emergency work to restore your malfunctioning boiler.

Boiler problems that require repairs

  • Frozen pipes: In a city that can get as cold as Pittsburgh, pipes freezing can become a major problem—and the pipes attached to your boiler are as susceptible as those attached to your regular plumbing. Frozen pipes will often burst, and you’ll need professionals to replace the afflicted sections. The repair technicians can also help you insulate your pipes to avoid freezing problems in the future.
  • Leaking: Any system that circulates water can suffer from leaking. Aging pipes, poor soldering, corrosion, high water pressure… all can lead to your boiler springing leaks. You need professionals to seal the leaks before it reduces your boiler’s heating ability, and also to find out what caused the leaks in the first place.
  • Sediment build-up in the tank: Over time, the water tank of a boiler can begin to collect sediment that will settle along the bottom of the tank. This sediment can contribute to rust and a dangerous increase in water pressure. Technicians can flush the tank to eliminate the build-up.
  • Limescale: If the water inside the boiler’s system is hard (i.e. it contains too much calcium and magnesium), the high temperature will cause a phenomenon called limescale to develop inside the tank as it heats the hard water. Limescale is in insulator, and this will unbalance the temperature in the tank, leading to high water pressure.
  • Cold water mixing in the tank: A broken mixing valve can cause cold water to enter the top of the tank and begin mixing with the hot water, causing a drop in water temperature throughout your home. If you notice rumbling from the tank, this is probably the reason.

Call for professional repairs

Boehmer Heating & Cooling can take care of the heating repair in Pittsburgh, PA you need to restore your boiler if any of the above happens. Don’t try repairs yourself… you may only cause further damage. Put your trust in our NATE-certified technicians.

Common Zone Control Heating Problems

Monday, February 24th, 2014

Either as an upgrade to an existing system or as part of a new installation, a zone control system makes a lot of sense. They divide your home into different sections, allowing you to raise or lower the temperature of each one separately. So one family member can turn up the heat in the bedroom to stay warm while another can turn it down while working over a hot stove in the kitchen. Zone controls help cut down on monthly heating bills since you can simply turn down the heat in areas of the home you aren’t using. What kind of issues might those be? It depends. Here’s a brief list of common zone control heating problems.

  • Stuck dampers. With any zone control system, you might have problems with the dampers or valves. If they won’t close (or stay stuck) then the zone they control can’t be heated or cooled the way you need it to. A technician can usually get into the duct system and fix the stuck damper with a minimum of effort.
  • Control panel. The control panel is what regulates the dampers in the zone control system, and because it is electrically powered, most of the problems with it stem from there. If it isn’t working, it may have a faulty component or there may be a problem with the electrical flow coming into it. In some cases, the component can be repair. In orders, the whole panel needs to be replaced.
  • Thermostats. The thermostats for each of your zones can have the same problems as a thermostat that controls the temperature in your whole house.  They can misread the temperature, fail to activate when they should or fail to turn off the system when the desired temperature has been achieved. A trained technician can repair or replace them as appropriate.

For help with common zone control heating problems, Boehmer Heating & Cooling is here to help. We handle all kinds of Pittsburgh heating repair services, and we can address the issues plaguing your zone control system with speed and efficiency. Call us today to make an appointment!

3 Causes of Boiler Leaks

Monday, February 17th, 2014

Boilers have a number of advantages that keep them competitive as heating options. Perhaps the most attractive one is longevity. Boilers have few mechanical parts, which means they are less prone to wear and tear due to age. With regular maintenance, they can last over two decades and require few repairs during that time.

It’s rare for any system to last that long without any repairs, however, and boilers do have a particular issue that sometimes needs professionals to fix: leaks. There are a few different reasons for leaks to occur, but no matter how they happen, they need immediate attention before the whole heating system is compromised or a house sustains water damage. Boehmer Heating & Cooling has worked on boilers since 1933; place your trust in us when it comes to your boiler in Pittsburgh, PA.

Three common reasons for boiler leaks:

1. High water pressure

Boilers are designed with an expansion tank to maintain water pressure inside the main tank as the temperature rises. But if a malfunction occurs that allows the pressure to increase or the water to overheat, it will start to cause leaks to spring up in multiple connections and valves throughout the boiler system. A professional will need to seal the leaks and discover the reason for the pressure spike.

2. Corrosion

Wherever water and metal meet, there is possibility of corrosion occurring. Although modern boilers are designed to resist corrosion, it can still occur because of oxygen infiltration into the tank. Corrosion weakens metal, and will soon cause leaking to begin. Corrosion must be removed as soon as possible before it spreads too far and requires a full tank replacement.

3. Improper installation

We cannot emphasize this enough: you must rely on professionals to install a boiler system. If your boiler received poor installation, it will lead to multiple troubles, but leaking is the most common. Untrained installers usually perform poor soldering jobs on the connections, and these will soon start to develop leaks. Although sometimes repairs from experts can fix initial installation glitches, often the whole boiler will need to be replaced.

If you detect leaks anywhere on your boiler, call for service right away. If you notice a decrease in heating power or hear a rumbling in the tank (often a sign of overheating), you should also call for repairs. Take good care of your boiler and it will reward you with many years of effective warming that will outstrip any other heating system.

Boehmer Heating & Cooling is available for 24-hour emergency service. We also offer maintenance plans to keep your boiler in Pittsburgh, PA in good shape all year.

What Makes a Furnace High Efficiency?

Tuesday, January 28th, 2014

The modern furnace makes better use of its fuel supply than the models of only a few decades ago. Many furnaces on today’s market carry the ENERGY STAR label from the U.S. EPA because of their efficient use of fuel and high return of heating power.

One type of furnace that goes above and beyond for energy savings is the high-efficiency condensing furnace. Where most furnaces can score AFUE ratings in the 80%–90% range, a high-efficiency model can climb as high as 98%—meaning only 2% of the natural gas goes to waste as exhaust.

Here’s an explanation for how these modern marvels achieve this. If you are interested in installation of a high-efficiency furnace in Pittsburgh, PA, talk to our specialists at Boehmer Heating & Cooling.

High-Efficiency Furnace Operation

The reason these furnaces waste so little energy is that they are capable of using the exhaust from the first part of the heating process to generate more heat. Here is how it works:

A standard furnace contains a single heat exchanger. High temperature combustion gas enters the chamber and heats up its walls. After air is blown around the exchanger and absorbs the heat, the cooled-down gas changes into a vapor. This vapor vents out the exhaust flue.

But a high-efficiency condensing furnace contains second heat exchanger. The exhaust vapor moves into this chamber, where it condenses into a liquid. The process of condensing causes a release of more heat, warming up the walls of the heat exchanger and providing additional warmth for the air that will be sent into the ventilation system. The liquid exhaust is then drained from the second heat exchanger.

The result of this is a reduction in energy waste. The more efficient performance means these furnaces will rapidly make up for their costlier installation with large savings off of heating bills.

High-Efficiency Furnace Repair and Maintenance

There is one drawback to high-efficiency furnaces which you need to know about: because they are more intricate machines that require a balance of many components, they require very attentive maintenance and repairs. All furnaces need regular maintenance and prompt repairs when necessary, but with a high-efficiency furnace you must take particular care of it or lose the benefits it provides.

Boehmer Heating & Cooling has maintenance plans that will make caring for your high-efficiency furnace in Pittsburgh, PA much simpler. Our 24-hour emergency service will also put you more at ease. Call us today for installation, maintenance, or repairs for your furnace.

What Does NATE Stand For and Why Is It Important to My Heating Repair?

Monday, January 6th, 2014

Our Pennsylvania winters get awfully cold, and you need your heating system to be reliable. That’s why professional Pittsburgh heating repair services are critical to the safety and comfort of your home, and why the term “NATE” matters so much in that equation.

NATE stands for North American Technician Excellence; it’s a non-profit certification organization designed to boost the credentials of HVAC repair services throughout the country. The organization was founded in 1997 in Arlington, VA, and tests the knowledge and experience of HVAC technicians everywhere. Because it’s a third-party organization, it can maintain its objectivity and customers can be assured that their findings are accurate. NATE-certified technicians have passed a strict series of tests designed to ascertain not only their knowledge in HVAC repair and similar fields, but the ways that they can apply that knowledge to heating and cooling systems. Because it’s so reliable, many cities, counties and states use NATE certification as a basis for their licensing procedures, ensuring that anyone who practices HVAC installation and repair within their boundaries can exercise a certain amount of competence.

That’s important because it helps you rest easy when your heating or air conditioning system goes down and you need a repair service to fix it. Looking for the NATE certification symbol helps you find a technician who can fix your system with confidence. For heating repair in Pittsburgh, you can count on the experts at Boehmer Heating & Cooling to help.

Is It Time to Get a New Furnace?

Wednesday, December 18th, 2013

The cold winter weather has arrived in Pittsburgh, and we hope that you’re cozy inside your home with your furnace keeping you warm. But if you’re not, or if your furnace is acting strangely, then maybe you need to consider a new furnace installation.

Furnaces can last for a long time with the proper care, sometimes past 20 years. But eventually they will start to run down, develop corrosion, and begin to work inefficiently, leading to a complete breakdown. If your furnace is nearing the end of its service life, you should have a new furnace put in before your current one shuts down at the worst possible time. With professional installers on the job, the switch from the old furnace to the new one will go fast and you won’t find yourself stuck in the cold.

Boehmer Heating & Cooling has years of experience with furnace installation; we’ve been in business since 1933! For your new furnace in Pittsburgh, PA, trust to us.

Here are a few of the signs to look out for that will warn you it’s time to get a new furnace:

  • Inexplicably elevated heating bills: As a furnace wears down with age, it will start to work harder to do its job. You may feel the same level of heating, but your furnace must drain more power to achieve it. Take a look at your heating bills each month: if they start to climb and stay that way, it might be the fault of a furnace past its prime and moving into decrepitude.
  • Extensive rusting: If you discover extensive rust along the bottom of the cabinet of your furnace, then it is likely time to get a new unit.
  • Constant noisy operation: One of the best warning signs a furnace can send that it requires repairs is a strange, loud noise. However, if a furnace begins to make rumbling, clanging, and grating noises on a regular basis, it usually means that it has become too worn down for regular repairs to restore it.

It’s a big step to decide on installing a new furnace, but it doesn’t have to be a difficult one if you hire a contractor with the experience necessary to make the installation go fast and smoothly. All of the installers at Boehmer Heating & Cooling are highly trained, so you’ll know that you are getting quality work when you hire them to install your new furnace in Pittsburgh, PA. Contact us today so you’ll have the best heating for the rest of the winter.

Furnace Problems Caused by Your Thermostat

Monday, December 2nd, 2013

The thermostat is a small object, but it performs a big job: it’s your means of communicating with the furnace in your home. If the thermostat develops malfunctions, it can threaten the comfort of your home.

When a thermostat starts to go awry, it can first appear as if something is wrong within the furnace cabinet or the ducts. This is one reason you should always rely on assistance from HVAC professionals when you have problems with your heating; attempting repairs on your own can lead to worse trouble if you are trying to fix something that isn’t broken. Call in experts like the ones on staff at Boehmer Heating & Cooling and let them locate the source of the trouble with your furnace in Pittsburgh, PA and find the best way to repair it.

Here are a few of the troubles you can experience with your furnace because of a faulty thermostat:

  • Furnace won’t come on: If the furnace won’t start up when the temperature drops, you should check the thermostat first to make sure you have it set correctly. If the thermostat has lost its connection to the furnace, it won’t activate the igniter. The thermostat might also be miscalibrated, so it senses incorrect indoor temperatures and registers the house as warmer than it actually is.
  • Furnace won’t stop running: A broken thermostat can also mean the furnace will continue to run, overworking its parts and making your home too hot. As with a furnace that won’t come on, this might indicate a thermostat miscalibration. Or it could be electrical trouble with the wire from the thermostat that switches the furnace on and off.
  • Furnace short-cycles: “Short cycling” is when the furnace comes on for only a brief period and then shuts off before completing its heating cycle. Again, this might be a thermostat miscalibration: the thermostat registers prematurely that the furnace has reached its target temperature and shuts it off. This will damage your furnace, drain power, and leave parts of your home cold.

Here’s something to keep in mind about thermostat operation: a thermostat is a switch, not a throttle. It turns your furnace on and off; it doesn’t increase the amount of heat it produces or speed it up. Turning the thermostat up to 90°F won’t heat up your home faster; it will just keep the furnace running until it reaches that point.

Get in touch with Boehmer Heating & Cooling when you need repairs for your furnace in Pittsburgh, PA. You don’t want a malfunctioning thermostat to leave you a deep freeze this winter. We have 24-hour emergency service to make sure you won’t stay cold for long.

What to Do if Your Boiler is Leaking Water

Monday, November 18th, 2013

When it comes to heating repair, Pittsburgh residents know better than to fool around. Our winters are as cold as they come, and a day without a reliable heating system is almost as miserable as watching the Steelers lose to the Ravens. That means looking for the warning signs of a problem, which may allow you to stop a smaller problem before it becomes a bigger one. If you own a boiler, keep a particular eye out for leaking water, which is one of the most common problems with such a system.

Leaks can develop anywhere in the system, and with a large house, that system may be quite extensive. Checking for puddled water is the most obvious way to pinpoint a leak, particularly around any connections or seals in the pipeline. Unfortunately, many leaks start out very small and the hot water involved can evaporate before it puddles on the floor. By the time you notice the water, the problem may be bigger than you’d like.

A smarter way to check for leaks is to monitor the overall pressure in your boiler’s pressure gauge. If you notice it starts to drop, you’re likely looking at a leak somewhere in the system. Pinpointing it can be difficult; the best thing to do is shut off the boiler for the time being and contact a service technician to give it a look. He can likely hunt down the source of the leak and instigate some high quality repairs.

If you know what to do if your boiler is leaking water, the next step is to contact a professional who you trust. The experts at Boehmer Heating & Cooling handle any heating repair in Pittsburgh, and we’re completely dedicated to fixing your boiler problems the first time, every time. Call us today and make sure the job is done right!

Furnace Sounds and What They Try to Tell You

Monday, November 11th, 2013

Science has yet to invent a home furnace with an artificial intelligence that allows it to tell you exactly what is wrong with it and what repairs you need to do to keep it working. However, furnaces do have an innate way of sending you warnings about impending repair needs and potential breakdowns: unusual sounds. If you’ve lived with your furnace for more than a year, you already have a good idea of what noises it makes during standard operation. When any out-of-the-ordinary sounds start to emanate from the furnace cabinet, pay attention to them and then make the necessary steps to get repairs done.

Usually, this means calling in HVAC experts. Both electrical and gas furnaces pose potential health hazards to anyone who tampers with them without professional experience. Boehmer Heating & Cooling has worked on furnaces since 1933, so we have the experience necessary to diagnose the problems with your furnace in Pittsburgh, PA and fix it effectively and safely.

Common furnace warning sounds

  • Loud clicking: There is often a simple reason for this noise: loose bolts on the outside cabinet. However, if you have a gas-powered furnace and find this isn’t what’s wrong, the culprit could the ignition, or possibly even a problem with the heat exchanger or gas supply. Any of these problems should be examined by a professional as soon as possible to make sure your furnace is operating safely.
  • Groaning, squealing: This is probably the motor bearings that operate the blower fans wearing down or malfunctioning because of dust. Get repairs done before the motors need to be replaced entirely.
  • Clanking: If the belt from the blower motor to the fan becomes cracked, it will come loose and begin striking against the casing or other components. You don’t want to attempt to change the belt yourself, even if you’re familiar with doing a similar repair with a car motor fan belt. Get professionals to replace the belt before it starts to damage other parts of the furnace.
  • Rumbling, booming: Dirt and grime have probably contaminated the burners, choking off their supply of oxygen and preventing the gas jets from igniting and providing heat to the combustion chamber. This can also affect the pilot light. The burners will need to be professionally cleaned.

Boehmer Heating & Cooling has technicians ready around the clock, seven days a week, to get you the repairs you need on your Pittsburgh, PA furnace. Don’t ignore those strange sounds in your furnace—get expert help from Boehmer Heating & Cooling right away.

Top 3 Reasons to Choose a Boiler in Pittsburgh

Monday, November 4th, 2013

Whether you choose to heat with a gas furnace or an older boiler, Pittsburgh residents need to know the benefits. We’re a tough town here in Steeler country, and our winters are as harsh as they come.  Whatever system you use to heat your household needs to be able to do the job for many years, and you have to rely on it to perform when life gives you other things to occupy your attention. Not every type of heating system fits every circumstance, and you’ll need to decide for yourself which one works best for your circumstances. Having said that, a boiler system – using hot water or steam to warm your household – offers a number of tangible advantages over other types of heating. Here are the top 3 reasons to choose a boiler in Pittsburgh.

  • No dust. Gas furnaces use a “forced air” system, which blows hot air through your home in an effort to heat it up. This can spread dust and debris around your house, which can exacerbate allergies and create irritation in the nose and throat. Boilers don’t need ductwork to circulate the warm air, so dust and debris won’t spread through your home like that.
  • Noise. Boilers are extremely quiet in their functioning, limited mostly to the burning gas or oil in the boiler itself.  That means you don’t have to put up with the sound in exchange for having a cozy and comfortable home.
  • Even heat. Along with the lack of dust comes a lack of drafts or cold spots in the home. The radiators in a boiler system warm the air evenly, increasing comfort levels and improving the overall quality of life in the home.

All of that comes with month-to-month costs that are comparable to gas furnaces and similar forms of heating. When looking at the possibilities of a boiler, Pittsburgh residents can talk to the experts at Boehmer Heating & Cooling. We can explain the reasons to choose a boiler in Pittsburgh – as well as the benefits of forced air furnaces and other forms of heating – then install your chosen unit with professionalism and pride. Give us a call to set up an appointment today.
