What to Do If Your Furnace Keeps Turning On and Off: Warrington Heating Tip

Monday, November 12th, 2012

If the Warrington home’s furnace turns on and then a short time later shuts off, this is known as short cycling. Not only is short cycling hard on your equipment, but it also greatly reduces the efficiency of your furnace. Below, we describe what you should do if your furnace is short cycling.

Causes of Short Cycling

There are a number of reasons that your furnace might be short cycling. Here are just a few of them:

  • Furnace is too big – In this case, your furnace will heat your home very quickly and then shut off. As your home cools again, the furnace will turn on and heat up your home once again. Having a properly sized furnace is critical to your home’s comfort and efficiency.
  • Clogged air filter – This is by far the most common cause of short cycling. When your air filter clogs, it restricts air from getting into your furnace. As your furnace heats up the heat exchanger, air is supposed to blow over the exchanger to carry the heat into your home. Without that air flow, your furnace will overheat and shut off.
  • Thermostat – Sometimes, the cause of short cycling is a malfunctioning thermostat. If the thermostat isn’t working properly, it could be turning the furnace on and off mistakenly.

Why Short Cycling is a Problem

  • More wear on your furnace – With all the constant turning on and off, it puts extra strain on your furnace. This increases the rate of wear and can also potentially increase repair costs.
  • Reduced efficiency – With the furnace turning on and off, it doesn’t get the chance to realize any kind of efficiency that comes from running for an extended period of time.

What To Do If Your Furnace Is Short Cycling

The first thing you should do is check your air filter. If it’s dirty, you should change it out immediately. Not only can a clogged air filter cause short cycling, but it can also be the cause of other serious issues with your furnace.

If that doesn’t fix the problem, then you will most likely have to call a heating contractor. Carney Plumbing, Heating & Cooling offers complete furnaces services in Warrington. If your furnace is short cycling we can come to your home, diagnose the problem and offer a solution.

Considerations for Oil to Gas Conversion

Monday, October 29th, 2012

If you’re considering switching your house from oil to natural gas fuel, it is a huge decision that requires careful consideration. Whether your boiler needs to be replaced or if the price of oil in your area has skyrocketed, switching to natural gas can be a good option for some homeowners. Below we outline some of the major considerations you should think about before switching over.

Availability of Natural Gas

While the United States is experiencing a boom in natural gas production, it still isn’t available everywhere. Depending upon where you live, you might be out of luck simply because the infrastructure isn’t there yet.

Cost of Conversion

This tends to be the area that discourages some homeowners from making the jump. The cost of converting your home from an oil-fired furnace to natural gas can expensive. However, some homeowners make that up in energy savings within 5 years. Obviously, that time-frame can vary drastically by region and your specific situation. If you don’t have a natural gas line right now, one will have to be installed. That involves digging up your yard and part of the street to bury a line and connect it to the main line.

Incentives

To encourage people to make the switch to natural gas, some gas companies will offer certain rebates or other incentives to reduce the initial cost of installation. These vary by region and company, but some will pay for a new gas-fired heater or pay to remove your old oil tank from your property.

If you have questions about switching to natural gas from oil, call the experts at Carney Plumbing, Heating & Cooling. We have years of experience helping our customers in Lansdale make the switch from oil to natural gas. Our friendly heating experts are available to talk to you and discuss your situation.

How is Geothermal Heating Different than a Boiler or Furnace?

Monday, October 8th, 2012

If you need a new heating system in Quakertown, there are quite a few options to choose from. But before we can talk about the differences between boilers, furnaces and geothermal systems we need to understand how they work.

How a Boiler Works

Boilers, like most traditional heating systems, require a fuel source, normally oil or gas, which is combusted in exchange for heat. In the case of a boiler, that heat is transferred to water that is circulated to radiators in each room where the heat from the water is expelled into the air.

How Furnaces Work

With furnaces, the heat generated by the burning of fuel is transferred to a piece of metal called a heat exchanger. The furnace blows cool air from the house over the heat exchanger which warms the air and it is then delivered to the rest of the house using a series of ducts.

How Geothermal Systems Work

A geothermal system uses a pump to circulate liquid, sometimes water or a mixture of anti-freeze and water, into the ground where it is either heated or cooled—depending upon the needs of the people in the house.

The Differences between Boilers, Furnaces and Geothermal Systems

The main difference between a geothermal system and a boiler or a furnace is that it doesn’t require any kind of fuel source. The energy for the geothermal system is actually in the ground. If you dig about 10 feet into the ground, the temperature of the soil stays at an almost constant 55° F no matter what the temperature of the air is above it. When the air in the home needs to be cooled, a geothermal system absorbs the heat from the air and transfers it into the ground. When the home needs to be warmed, the process is reversed: heat from the ground is absorbed by the liquid in the pipes and transferred to the air in the home.

The only energy being used is the electricity to run the heat pump that circulates the liquid in the pipes and the air handler to distribute the conditioned air.

If you’d like to learn more about installing a geothermal system or to see if your property in Quakertown can support one, call Carney Plumbing, Heating & Cooling today.

Benefits of Heating Maintenance for Your Furnace

Monday, October 1st, 2012

Your furnace is like any other piece of equipment in your Langhorne home in terms of what it needs to continue to function at a high level – namely, routine professional maintenance. Even if your furnace is relatively new, it’s never too early to start planning to keep it in good working condition for years to come. Routine heating maintenance is the best way to ensure your furnace will always work when you need it to.

Better Energy Efficiency

One of the most immediate benefits of regular furnace maintenance is the boost you’ll see in your system’s energy efficiency as reflected in lower energy bills going forward. Even the newest, most efficient furnace will lose a measure of its energy efficiency every year. While this drop might not be noticeable at first, it will quickly add up to create higher heating costs for you. But a simple tuneup every year from a Langhorne heating technician can almost completely eliminate this loss in efficiency.

Fewer Repairs

A regular checkup also allows an experienced technician to go through your entire heating system to find any parts that need to be replaced and other issues that could cause problems later on down the line. Addressing these small issues early makes it less likely you’ll need emergency repairs in the middle of winter when your heating system suddenly shuts off. And that saves you both money and aggravation.

Avoid Premature Replacement

Keeping up with regular furnace maintenance will also extend the life of your system, making your initial investment go farther and allowing you to postpone replacement. And that’s always a good thing for your budget as well as for your peace of mind.

With so many benefits stemming from routine maintenance for your heating system, there really is no reason not to get it done. It’s actually quite a quick and inexpensive process, and you’ll be able to rest easy knowing that you did everything you could to make sure your family is warm and comfortable all winter long.

Heating Guide: Boiler Maintenance

Monday, September 24th, 2012

If you own a boiler in Jamison, regular maintenance is very important. Performed in the fall, before your boiler is turned on for the first time, this maintenance will ensure your system works properly and efficiently for the coming months. Here are a few of the tasks performed by a Jamison heating professional during a maintenance call visit:

  • Clean Surfaces – The front and rear doors to the boiler are removed and the surfaces are all vacuumed and cleaned carefully.
  • Gasket Repair – All gaskets on the doors are checked and replaced if necessary to ensure your system works properly. Similar repairs are performed on the hand hole and man hole plates and the low and auxiliary low water cut off controls.
  • Burner and Pilot – The burner plates and pilot light are thoroughly inspected and cleaned. A technician will also check the pilot electrode and then test the pilot to ensure it works as intended.
  • Air Damper – The air damper and blower are both cleaned and tested for potential issues before turning back on.
  • Burner Adjustment – The burners are tested and adjusted for proper combustion and tests are performed to ensure the flame is right. Flame safeguard and safety trip checks are also performed to ensure the system will turn off as needed.
  • Control Piping – The control piping plugs are removed and cleaned, as is the entire pathways between

Boiler maintenance is the most effective way to ensure your heating system continues to work properly throughout the coming winter. Because of the nature of a boiler and the fact that most systems use natural gas or oil, it is important that a professional be the one to perform the above tasks. Call Carney Plumbing Heating & Cooling today to schedule your appointment!

Steps to Take When Your HVAC System Breaks Down

Monday, September 17th, 2012

If your Chalfont heating or air conditioning system breaks down, there are a few simple steps you should take before calling a professional. Here is a rundown of exactly what you should do and how these steps will ensure the system is fixed quickly and properly to help keep your family comfortable at all times.

  1. Check the Power – First, check the electrical power to your system. Look for a blown fuse or flipped circuit if the system won’t turn on at all. If this is the problem, watch for a recurrence. If it happens more than once, you should call a professional to fix the problem in the future.
  2. Check the Thermostat – Check all of your thermostats to ensure they are not only reading the proper temperature, but that they are set to the right temperature. Often, what seems like a big issue can simply be due to a thermostat being set wrong.
  3. Inspect the Outdoor Unit – Check outside for debris or brush around your condenser unit. This can block air flow and cause the system to shut down.
  4. Inspect the Indoor Unit – Check your indoor units for the same buildup of debris around them and for any other issues like dirt or dust on the coils.
  5. Check the Filters – While a clogged filter would not necessarily shut down an HVAC system under normal circumstances, it could lead to such a problem if it gets bad enough.
  6. Call a Professional – Finally, if you try everything listed above and you cannot get your air conditioner or heating system to turn back on or run consistently, now may be the time to call a Chalfont heating professional for a thorough inspection. This is when it could be a real breakdown which is likely more costly to repair.

If you have a problem with your air conditioner or heating system, definitely check common issues that could have led to the breakdown, but always call Carney Plumbing, Heating & Cooling if real repairs are needed.

Benefits of Forced Air Systems

Monday, August 13th, 2012

Forced air systems are usually hooked up to both a heating element and an air conditioning element, both of which send their pre-treated air through a series of ventilation ducts located throughout a building.  Many times the heating and air conditioning devices are separate, such as a gas furnace for heating and a central air conditioning unit for cooling.  Other times they can be one and the same unit like with packaged air conditioners and heat pumps which does both jobs with one machine.  This makes for a great deal of variety in the choices of heating and air conditioning types that are available for use.

With use of a programmable or digital thermostat there is a high degree of control with a forced air system.  You can Set time-of-day and day-of-week settings to accommodate when the building is in use and when it is not.  There are also options for setting temperatures in certain sections of your home while other sections remain untouched.  All of this allows for lower utility bills, since only the rooms which are used frequently are heated or air conditioned.

Air conditioners and heaters utilized today have much higher energy efficiency ratings than those of years past; couple this with a well maintained, properly sealed, insulated and balanced duct system and the energy-savings increase even further.

Forced air systems cost anywhere from 40% to 60% less to install than comparable radiant systems.  They also offer special features such as filtration systems and ultra-violet germicidal lights, which can keep your indoor air clean and healthy.

Carney Plumbing, Heating & Cooling is an air conditioning and heating company in Horsham that provides quality HVAC services to each client.  Let us assist you in determining which forced air system is right for your unique needs.

What Exactly Are High Efficiency Boilers?

Monday, April 2nd, 2012

You have already read plenty about how energy costs are rising. You know plenty well that heating your New Hope home is a substantial expense, and that the cost of running a boiler is constantly on the rise.

But as technology has gotten better, so have boilers become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?

 What Is a High Efficiency Boiler?

All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by your New Hope boiler compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.

For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.

In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.

These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a high efficiency boiler.

The initial investment in a high efficiency boiler can be costly, but the savings over time in your New Hope heating bills make it well worth the expense.

If you would like a high efficiency boiler installed in your home, give Carney Plumbing, Heating & Cooling a call today!

What Is an Electronic Ignition on a Heating System?

Monday, March 26th, 2012

Gas furnaces are very complex pieces of equipment to have in your Doylestown home. Modern ones in particular are designed to use as little gas as possible, and to recapture as much of the heat generated from burning that gas as can be done safely. One of the many safety and energy-efficient advances in furnace technology in the least twenty years is the electronic ignition.

 The Purpose of Electronic Ignition

In older furnaces and boilers in Doylestown, a pilot light would stay lit continuously whenever the heating system needed to be available. That meant continuously burning gas throughout the fall, winter and spring months for those times when heat was needed. It was inefficient and unsafe, especially in older devices that didn’t have safety valves.

Today, furnaces are built with electronic ignitions – small devices that only ignite the gas supply when the thermostat is on. there are two types of electronic ignition used in boilers and furnaces today.

  • Intermittent Pilot – An intermittent pilot is unique in that it releases a spark through an electronic component to the gas pilot, lighting the gas burners.
  • Hot Surface Ignition – Hot surface ignition uses an electronic filament (like a lightbulb) to heat up and ignite the burners when the thermostat calls for heat.

Both devices are designed to use a very small amount of electricity and reduce the amount of gas needed for continuous operation of your furnace.

Safety Benefits of an Electronic Ignition

While gas efficiency was a big part of the transition from pilot lights to electronic ignition, safety was an equally big component. Whereas before, the pilot light was continuously lit, meaning gas was continuously flowing into the furnace, today’s furnaces are essentially off when not in use. This means less of a chance that gas will flow unburned or that the pilot will get dirty or burn too soft, releasing carbon monoxide.

If your furnace or boiler still uses a traditional pilot light, consider having it upgraded to electronic ignition, not just to save gas but to keep your home and family safer.

Heating Tip: Simple Steps to Prevent Heat Loss

Wednesday, March 7th, 2012

There are two fundamental ways to make your Fort Washington house warmer. One is to generate heat, which is the job of your furnace or boiler. The second is to keep the warm air in — and thereby keep cold air out — which is the job of your system of insulation.

The idea that the physical structure of a home can be a component of the HVAC system is one that is often overlooked, but when you think about it, it makes sense. The insulation, windows, doors and building materials that comprise your home are designed to keep the place warm against the cold and vice versa.

So, when bolstering your HVAC system to promote efficient heating, it is important to also consider heat loss and how to prevent it. This is a process that can get out of hand if you go overboard, so it is important to prioritize. Let’s look at the top 3 places to start when trying to prevent heat loss.

  1. Doors and Windows:  If you have older doors and windows, they could be a source of heat loss in your house, even if they are always closed. Replacing your windows and door with Energy Star rated ones will make sure that you are not losing heat to the outside AND still getting all the heat energy from the sun. Installing storm windows or putting up heavy curtains in winter can also help cut down on your heat loss.
  1. Seal off drafts. If any opening to your house, such as windows and doors, is improperly sealed, improperly installed or if the surrounding construction is deteriorating, you can lose a lot of heat. Check any drafts that you notice that might indicate a problem, and also if your vents and air ducts are leaky.
  1. Start at the top. If you want to go farther in sealing your house up against the cold, it is time to work on the insulation. When installing new insulation, remember that heat rises, so you get the most bang for your buck by starting at the top. If you only have the budget or time to insulate one space, make it the attic. You can work down from there.

These areas should be your top three priorities on your mission to prevent heat loss in your Fort Washington home. If you start here, you will get the best gains with the least effort. If you have any questions about how to keep your house warm this winter, give Carney Plumbing, Heating & Cooling a call today!
