Woodcliff Lake Heating Tip: How to Check if Your HVAC System Is the Right Size

Monday, October 15th, 2012

Do you ever feel that your Woodcliff home just doesn’t get cool enough during the warm months or warm enough during the cold months? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard and the furnace in your basement should be making your home as comfortable as possible. But in many cases, they are not.  That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

So how do you check for the right size? Call a professional HVAC contractor and ask for an audit for your home. The audit will include several key checks including a load calculation, which adds in the size of your home’s living space, number of door and windows where heat loss or gain could occur, and a check of heat loss or gain through leakage in cracks, roofs, crawlspaces, etc. An audit will determine what size of furnace or air conditioner is needed to meet the heating or cooling needs of your home and its own individual characteristics. Your HVAC contractor may also factor in the number of building occupants and normal usage patterns, i.e. having a home office or stay-at-home parent versus a working family where your home is occupied mostly at nights or on weekends.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your Woodcliff  HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your home to when each zone is occupied.

Make sure you don’t hire someone who “guesstimates” how much cooling or heating capacity you need for your home. Find a qualified Woodcliff heating professional who will make the correct calculations and who will qualify their recommendations. A properly sized HVAC system will equate to manageable utility bills and above average indoor comfort.

Allendale NJ Heating Question: What Causes Cracks in a Heat Exchanger?

Monday, October 8th, 2012

Your Allendale NJ furnace is designed so that the heat – and the combustion byproduct produced inside – doesn’t interact directly with the outside air. This design is to ensure you have a safer furnace.

The metal piece that separates the furnace heat from the outside air stream is called the heat exchanger. The heat exchanger performs a very important function, and if it is broken or cracked, it can’t work properly.

A cracked heat exchanger is very common problem with Allendale NJ heating systems, as well as one that should be repaired as soon as possible. But what causes a heat exchanger to crack? Here are some of the most common reasons:

  • A long period of normal use. A furnace heat exchanger naturally expands and contracts with the heat of the furnace, over and over again as the furnace is turned off and on to heat the home. Over several years, this stress can crack the metal.
  • Poor air flow, often caused by dirty or obstructed vents, can result in poor air flow through the furnace. This overworks the furnace, which can crack the heat exchanger prematurely.
  • Poor, incomplete or improper combustion can also cause a heat exchanger to crack. When the combustion process is less efficient – which can also be a result of poor air flow — your furnace’s burners have to run hotter and longer to heat your home, which means extra stress on the heat exchanger.

Essentially, if a furnace is running at less than optimal efficiency for an extended period of time, the heat exchanger is put under additional stress beyond the usual and can crack prematurely. Therefore, the best way to prevent a cracked heat exchanger is proper maintenance, particularly keeping all vents clean and unobstructed and getting an annual maintenance inspection.

If your heat exchanger does crack, do not hesitate to call DB Heating & Cooling and get it repaired.

Hohokus Heating Question: What Is an Electronic Ignition?

Monday, October 1st, 2012

Gas furnaces are very complex pieces of equipment. 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 in Hohokus, 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 Hohokus furnace 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. For more information about features in new heating systems, give DB Heating & Cooling a call!

Emerson Heating Guide: Simple Steps to Prevent Heat Loss

Monday, September 24th, 2012

There are two fundamental ways to make your Emerson 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 your Emerson 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 Emerson 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 home. If you start here, you will get the best gains with the least effort. For more information about heating your Emerson home, give DB Heating & Cooling a call!

Allendale Heating Guide: Dangers of Not Changing Your Furnace Filter on Time

Monday, September 17th, 2012

Of the many ways to heat a home in Allendale, forced air systems are the simplest in function and the easiest to maintain.  They are so simple, in fact, it is easy to forget they need attention at all, but there are dangers to not changing your furnace filter on time that have a real and painful cost in efficiency and dollars.  Even health risks arise when filters have been neglected too long.

Contracting with a company like DB Heating & Cooling, Inc. ensures consistent maintenance and oversight to allow home owners the comfort and relaxation you deserve in your own home.

Back to Basics

Usually in the basement or a central location, a furnace heats air to a temperature set by the thermostat. By a fan in the furnace, the warm air is circulated through filters into a system of ducts to be distributed to grates in the wall or registers on the floor.  A second grate and duct system returns cooler air back to the furnace to be reheated.

Water can be added at the furnace to humidify the air and filters are able to remove some of the dust that typically floats invisibly throughout a home.

The Dangers of Not Changing the Filter

When the system is properly maintained, it is clean, efficient and produces comforting heat on demand at the touch of the thermostat or consistently throughout the day and night.

The furnace filter is designed to remove dust from air as it passes through your furnace. The longer your furnace filter is in place the dirtier it becomes. The increase of particles caught in the filter creates resistance to air flow through the filter and reduces efficiency.

To make up for the loss of flow through a dirty filter, the heat exchanger, usually a gas or oil fired flame, must work harder to produce the same amount of heat to the space.  This becomes costly financially and causes undo wear and stress on the equipment, requiring a partial or full replacement much sooner.

Additionally, operating above ideal designed conditions, cracks in the chamber may appear from the over load which can allow carbon monoxide, a toxic gas, to be released into the duct work.  This gas in large quantities in the home can cause headaches, nausea, and in extreme circumstances, even death.

Regular Maintenance

To avoid problems and excessive strain, remember to change the filters at the beginning of each new heating season.  An annual maintenance, check-up and thorough cleaning by a qualified Allendale HVAC company like DB Heating & Cooling, Inc ensures a safe and comfortable season of warmth with no need to worry about the dangers of not changing filters in your furnace.

Teaneck AC Contractor Tip: Green Your HVAC

Monday, May 21st, 2012

Regular Maintenance Avoids High Costs

No matter the energy rating of the appliance, a schedule of simple maintenance and replacement of filters can make a significant difference in its longevity.  A furnace rated at 95% efficient will burn nowhere near that great a rating if the air is blocked and unable to pass through the filter without effort.

Fan belts on the blower motor can loosen over time and become ineffective, forcing the heater to burn longer and hotter to distribute air that should normally breeze through the ductwork.  Working so hard, parts break and the furnace might need replacement.

New Thermostats

If left to our own habits, our Teaneck air conditioners and furnaces might run for hours under unnecessary circumstances because we are not thinking to turn our thermostats up or down.  At the change of seasons, in particular, it may feel warm enough to open a window while the heat is still adjusted to come on at those fresher temperatures that now seem so inviting.

In older homes, the replacement of the old dial thermostats with the newer digital versions can save on energy costs.  Smart phones allow adjustments to thermostats from anywhere in the world for the instance that a cold snap may threaten frozen pipes while we are away on vacation.

Changing World

Tax incentives, climate change and the economics of energy dictate that we look closely at our habits and find ways to conserve our resources. For more information about how HVAC improvements can reduce your energy bills, give DB Heating & Cooling a call today!

Paramus Heating Question: What Is Involved in Replacing an Old System?

Wednesday, February 29th, 2012

When your Paramus home’s HVAC system starts to fail — or if it already has — your options essentially come down to two: replace or repair. There are a lot of factors that go into making such a decision, but in general, if it is a newer system with a small problem and you haven’t had much trouble with it, then a simple repair clearly makes sense.

For older systems, or ones that have been repaired all to often lately, or ones that seem to be on their last legs, repair may be the only reasonable course of action.

Surely you know that a total system replacement would be a big job, but have you ever thought about just how big? Sure, you know you will have to swap out the failing furnace, and you may as well replace the air conditioning unit while you’re in there, but that’s it, right?

Actually, there is a lot more to an HVAC system than just those two machines. Think about all the behind-the-scenes components and the little components that are often overlooked, such as:

  • Ducts – Keep in mind that your ducts are probably as old as that furnace you are replacing, and that a new, efficient unit cannot operate at nearly its full potential with faulty duct work.
  • Thermostats – Your old ones may not even be compatible with a new furnace or air conditioner.
  • Wiring – For the thermostat, among other things.
  • Insulation – Many homeowners forget that insulation is part of an HVAC system, too. Just like we said about duct work, old insulation does not help a new system achieve maximum performance.
  • Piping – Such as refrigerant piping on a geothermal system or a ductless air conditioning system.

You can see that the job starts to get pretty complex pretty fast. This doesn’t mean you should shy away from a necessary replacement, just make sure that you fully consider the scope of what you need done, as well as the budget and time frame you have to work with.  If you are thinking about having your old system replaced, give DB Heating & Cooling a call!

Hackensack Heating Contractor Tip: Little Known Ways to Prevent Heat Loss

Wednesday, February 1st, 2012

Finding new ways to lower the heating bills for your Hackensack home is always a challenge. Maybe you’ve already insulated and sealed every crawlspace and crack, or you might have recently upgraded that old furnace, but there are always other ways to reduce heat loss in the winter.

Here are four ways to conserve heat that you might not have considered.

1. Insulate Recessed Light Fixtures

While recessed light fixtures save space and give you more control over lighting and design, such as task lighting in kitchens, they can be a hidden source of heat loss. Feel around your recessed lighting fixtures to see if there’s cool air or a draft. If you do, they could need more insulation. However, you have to be extremely cautious about what type of insulation you use around electrical wiring and fixtures. Check with the manufacturer, or call an electrician if you aren’t sure what  type of insulation to use.

2. Open Curtains on South End

The southern end of your home will get the most sunlight in the winter. If you have curtains or blinds on your windows or doors, leave them open during the day, and make sure you close them at night. Opening them will help warm up the home naturally during the day, and closing them will help keep the cold air out and warm air in at night.

3. Storm Windows and Doors

Many homeowners know they have the option of upgrading old doors and windows that leak air, but not everyone can afford to upgrade all the doors and windows at once. You can also install storm windows and doors to help reserve heat. Before you start comparing prices, remember to measure, since measurements will affect the cost.

4. Close Fireplace Flue

Whenever your flue is open, you are losing large amounts of heat. Close the damper if the fireplace or chimney is not being used. You can also consider upgrading to a more air tight damper.

You can always call DB Heating & Cooling, Inc. whenever you have questions about lowering your heating costs for your Hackensack home.

Waldwick Heating Guide: Comparing High-Efficiency and Mid-Efficiency Furnaces

Wednesday, January 4th, 2012

Whenever you are in the market for a new furnace for your Waldwick home, there are many models to choose from.  Many of the furnaces manufactured within the last few years are high-efficiency furnaces with a high AFUE rating (AFUE measures the amount of fuel the furnace converts into heat). When people refer to a mid-efficiency furnace, they are usually talking about older furnaces.

Single-stage furnaces were considered to be an efficient heating system when they were manufactured, but compared to newer furnaces, they use up a lot more energy than they need to. Single-speed furnaces are designed to run at full capacity until the temperature inside the home reaches the thermostat setting. After they shut off, the home not only loses heat, but the furnace will also take longer and burn more fuel when it cycles on again.

Newer, two-speed and multispeed models run consistently at lower speeds, and the ones with variable-speed blowers are even more efficient because they can operate at various levels. These models will also automatically adjust to the thermostat to maintain a constant temperature, which saves energy by keeping the home at a consistent temperature so that there’s little heat loss.

When shopping for a new furnace, keep in mind that the AFUE ratings for multispeed and variable-speed furnaces only determine the efficiency of the actual furnace. If you are upgrading your old, mid-efficiency furnace to a high-efficiency furnace, you should make sure that your Waldwick home is properly insulated and sealed.  You could also consider upgrading any older doors and windows to more efficient double-paned ones, or you can also install storm doors and windows.

Waldwick Heating Service Tip: Furnace Air Temperature

Wednesday, December 14th, 2011

When your furnace turns on every day and warms your Waldwick home, just how hot is the air being blown through your vents? It’s a common question and while it varies depending on the type of furnace you have and the length of your ductwork, normally, the air is about the same temperature in most homes.

The Heating Process

When you turn on your furnace, it ignites fuel (gas or oil) or heats elements (electricity). A blower fan blows air through the heat exchanger and then into ductwork that distributes the heated air to vents around your home. When the combustion occurs and air is first heated, the temperature is between 140 degrees F and 170 degrees F.

This is extremely warm and could be dangerous to anyone if they got too close to it or it was blown directly into your home. However, as the heated air is distributed into your home it starts to cool. In some cases, it loses a significant amount of its energy in the ductwork.

This is intended, of course, because the temperature would be much too high if it was distributed directly to your rooms. That’s why high velocity ductwork often requires regulation to avoid overheating of the air. Cooling like this is normal and results in a better, more evenly distributed airflow.

When Something’s Wrong

To know something is wrong with your heating system, you must first understand what temperature air normally is when distributed through the vents. This will vary depending on which room you are in and how big your home (and furnace) are. However, if you notice a sharp drop off in comfort level in your home, it takes longer to heat rooms when cold or if that heating is suddenly uneven, it may be time for someone to inspect your furnace and check for potential problems.

A technician will then check to see if the air is being heated to the target 140-170 degrees F or if heat is being lost in the air handler or ductwork. There are a number of issues that can contribute to lost heat in your heating system – the easiest way to be sure the problem is solved properly is to call a professional when you notice the problem.
