West Chester HVAC Guide: Different Types of Furnace Filters

Wednesday, March 7th, 2012

A good filter for your West Chester home’s furnace is a must. Because that device heats and blows air throughout your home, you want to be sure that it doesn’t recycle contaminants and bacteria that could easily be captured at the air handler. That’s why it’s vital to choose the right furnace filter on the first try. Here are some furnace filters to consider and their various benefits to your home and family:

  • Electrostatic – Most electrostatic filters are permanent and must be washed on a regular basis. They are electronically charged to capture particles as they pass through, much like a magnet. These filters are effective because they are both physical and electronic. However, keep in mind that they are only as efficient as the cleaning they receive.
  • HEPA – HEPA is the highest rating available for a filtration system, removing up to 99.9% of all particles as small as 0.3 microns. However, they are also inefficient when used in furnaces as they severely reduce air flow. They are not often recommended for this reason.
  • Pleated – Pleated filters come in both reusable and permanent forms and can be either purely mechanical or electrostatic. There is a very wide range of efficiency ratings for pleated filters so make sure you analyze your home’s specific needs before selecting any one pleated filter.
  • Activated Carbon – Activated carbon is unique from the other three filter types because it effectively removes fumes, odors and chemicals from indoor air along with other larger particles. It is recommended that if you choose an activated carbon filter, you supplement it with a pleated or electrostatic filter (or choose a combination filter) to remove all unwanted components from your home.

There are a lot of options when it comes to furnace filters. To make sure you get only the best air quality, talk to Cool It Heating & Air Conditioning who can help you determine which pollutants are the biggest problem in your home.

Concordville Heating Tip: Sources of Carbon Monoxide

Monday, December 26th, 2011

The risks of carbon monoxide have been well documented for years. It can be fatal at high concentrations, but even in low levels in your Concordville home  it can be poisonous enough to make you sick.

What you may not know is that there are many sources of carbon monoxide, also known as CO. This poisonous gas is formed by any incomplete combustion process. Since combustion is not 100% efficient, that means carbon monoxide is released any time something burns.

To be more specific, here are some examples of carbon monoxide sources you might encounter around your house:

  • A furnace or chimney can leak exhaust gases, including CO, into the home if it has been improperly sealed or vented. For example, if the chimney has a small crack in the flue that goes unnoticed, CO from the fireplace can be vented back into the house.
  • A furnace supplied by an under-sized gas line will often burn the gas at a sub-optimum temperature. The result is incomplete combustion of the gas, which means a source of CO.
  • Old, dilapidated or poorly maintained heating systems are a big culprit. Often the seals or fittings are loose on these units, causing CO to leak out of them and into your house. Or they may not burn fuel as efficiently as they used to, so carbon monoxide is more readily released.
  • Using machinery, like a propane generator or a gas-powered saw, in a poorly vented garage can be very dangerous. Sometimes people don’t think about this one because the garage is large enough that it seems to be ventilated better than it is.
  • There’s a reason that barbeque grills are labeled for outdoor use only: they release a lot of carbon monoxide. Both charcoal and propane grills should only be used outdoors, and you should avoid the smoke from charcoal in particular as much as possible.
  • Smoking tobacco releases carbon monoxide into the air, along with other potentially dangerous gases.

There are plenty of other sources, as well, but those are some common ones. To protect yourself and your family, make sure any areas where combustion occurs are well-ventilated, keep your HVAC equipment well-maintained and in good repair and invest in a home CO detector. They are inexpensive, and many are combined with a smoke detector, so you only need to buy one unit.

HVAC Safety the Whole Family Should Know: Some Pointers from Haverford

Wednesday, November 16th, 2011

If you think the most important thing a heating and cooling (HVAC) system can do is to provide an comfortable environment in your Haverford home, you are right. But there is another thing an HVAC system does that is very important and it affects your entire family. It provides a safe indoor environment, too.

Besides warmth in the winter, a finely-tuned HVAC system can clean and filter the air you breathe. That’s important to people who suffer from allergies and is especially important for minimizing the spread of germs that cause colds and the flu. The key phrase in this paragraph is finely-tuned. If your HVAC system is not working correctly – out of tune – it can cost you a great deal in monthly utility bills and can be harmful to your health.

It is important for you and your family members to understand the basics of HVAC system maintenance so you can all understand the symptoms of improper maintenance and its consequences. For example, if anyone in your home is suffering from flu-like symptoms or are constantly drowsy or listless, they may be suffering from the a silent killer: poisonous carbon monoxide gas. This gas is formed during incomplete combustion of fossil oils like natural or propane gas. A malfunctioning furnace can emit carbon monoxide gases and you may never even realize it, until it is too late. Long-term exposure to the gas can cause brain damage and/or chronic sleepiness. It some cases, it can even cause death.

You may be able to diagnose the problem, but you aren’t qualified to test and repair a furnace that is creating deadly carbon monoxide gas. Your best bet is to call a qualified HVAC contractor who can diagnose the furnace and offer repair or replacement suggestions. But there are things you can do to prevent the build-up of carbon monoxide gas.

Check all exhaust vents, like chimneys and flues for any blockages. A blocked or partially blocked vent can cause the build-up of carbon monoxide gas. And never, EVER, use a gas or propane powered heater in an unvented area of your home. These types of heaters create various levels of carbon monoxide gas that needs to be circulated out of each room and replaced with clean, fresh air. So, your family can actively ensure that there is no debris, bird’s nests, animals, leaves, or snow in the ventilation system.

You can also “help” your HVAC system by keeping vents clean by vacuuming dirty vent grilles and, in general, keeping the home clean. The cleaner the home, the easier it is for your furnace to do its job and the easier it will be for you and your family will breathe. These are a few easy maintenance tips will keep you and your family warm – and safe – this fall and winter.

Electric Furnace Maintenance Tips from Chadds Ford

Wednesday, November 9th, 2011

Electric heat is clean – but Chadds Ford homeowners pay for that cleanliness with high utility bills. Depending on the area of the country, electric bills can rival those of gas, oil, or propane. So it is only natural to assume that an efficiently running electric furnace is a must for homeowners who are looking to keep their energy costs down.

Electric furnaces are fairly simple machines. They use heating elements to warm the air, which is then distributed through the ventilation system via a fan or blower. The heating element is made up of a metal wire that is heated by normal electrical current. The element is used to warm or heat something, much like the function of an oven or toaster. Their operation is fairly simple – either they work or they don’t.

When a heating element fails it is usually because it is broken, bend, or misshapen. When that happens, it is time to replace it. You can do some preventive maintenance with a visual inspection of your heating elements. If your inspection does not reveal any problems, you can test the element for continuity. You should know how to use an ohmmeter to test it or ask a professional heating and cooling technician to check the elements for you.

Speaking of visual inspection, you can do a quick check for any frayed or damaged wires, which can be a source for wasted electricity, too. Another way to ensure that your electric furnace is running efficiently is to replace or clean your furnace filters on a regular basis. A clogged filter can make a furnace work harder and lead to premature mechanical failure.

And obviously, if the furnace is not working it is best to check for any blown fuses or tripped circuit breakers in the main electrical panel box. If you find one, make sure you replace it with another of the correct amperage.

Lastly, check to make sure the blower motor is operating correctly. You can have perfectly working elements but if the blower can’t push the warm air through your ventilation system, then all of the steps to ensure the electricity is working are for naught. You can usually hear a noisy motor or smell one that isn’t working improperly. Check it on a regular basis and check the fan belt for any damage or slippage, too.

As you have read, an electric furnace is a very simple machine with simple working parts. Maintaining it is just as simple. If you have any questions, talk your local contractor.

Heating System Preventative Maintenance: Some Pointers from Narberth

Monday, November 7th, 2011

Ben Franklin once said, “An ounce of prevention is worth a pound of cure.” His famous quotation can apply to many things in life, including the heating system in your Narberth home. While heating systems in Ben Franklin’s time consisted of wood burning stove and fireplaces requiring little maintenance, today’s sophisticated furnaces and building controls require a good dose of preventative maintenance in order to avoid mechanical failures and inefficient operation.

For example, a furnace runs better and lasts longer when you maintain a regular schedule of filter cleaning or replacing. A dirty or clogged filter can restrict airflow from the furnace into your home’s ventilation system and cause the furnace to work harder, putting more wear and tear on it and taking months, if not years, off of its useful life. If your furnace uses disposable filters, check them every month and replace them if necessary. If your furnace uses an electronic filter that requires cleaning, check it on a monthly or semi-monthly basis and clean it with soapy water and a hose. Be aware of the change of seasons which could add extra pollutants into the air like pollens, ragweed, and cottonwood. This debris easily finds its way into the filters and creates an unhealthy indoor environment.

You can also perform a simple visual inspection of working components inside your furnace by removing the access cover and checking – with a flashlight – for loose fan belts, frayed electrical wires, or a build-up of dirt and dust. Simple solutions include tightening or replacing belts, repairing wiring, and vacuuming out dirt and dust with a hose attachment. All of these actions will keep your furnace working better and prevent future failures.

You can also do a visual check of your home’s ventilation system, paying close attention to any cracks in duct seams or holes in flex ductwork. Using sealing cement or duct tape can usually fix these problems and allow for better, unrestricted air flow. Again, these actions will help your furnace work more efficiently and avoid premature failures.

Maybe the best advice for preventing heating system breakdowns is to have a regular maintenance schedule with a local qualified heating contractor. Most contractors can set you up with annual furnace and ventilation system inspections. Having a service agreement – as a rule – gives you priority emergency repairs and discounts on parts and services. Besides that, planned maintenance is also preventative maintenance, something that will give you peace of mind in the long run.

Different Types of Furnace Maintenance: A Guide from Gradyville

Friday, October 28th, 2011

If you haven’t done so already, take your automobile owner’s manual out of your glove box and check out the section where it lists regularly scheduled maintenance. You will probably see that the most frequent maintenance tasks are changing the oil, checking fan belts, changing windshield wipers blades, checking all fluids, and checking tire pressure. These are regular, routine tasks. You will also see other tasks like changing fuel filters, flushing radiators, and changing transmission fluid.

You know that there are different types of maintenance tasks associated with keeping your automobile in tip top shape. Did you also know there are tasks that can be performed at various intervals to keep your home’s furnace in peak running condition? Well, there are.

For example, the most frequent maintenance task is checking the filters in your air handling unit. These are often called furnace filters but in reality, they serve the same function to filter air to and from your air conditioner, too. It might be easiest to just call them air filters. The frequency of replacing or cleaning air filters usually depends on the type of indoor environment you live in – like humidity levels, number of household pets or occupants, etc. In general, filter maintenance should occur every one to three months.

A less frequent maintenance task is cleaning the moving parts of the internal mechanism. You may only need to have your furnace cleaned every six months to a year, depending on its use. In some cases you can perform the cleaning yourself or it is included in an annual cleaning as part of a service agreement with a qualified heating and cooling contractor. A furnace can typically run at peak efficiency when it is cleaned on an annual basis.

You can also make it a regular habit of checking the motor bearings and fan belt, too. You can lubricate the bearings and tighten or replace the fan belt on a same schedule as cleaning the moving parts.

Other maintenance tasks related to your furnace, which may require longer interval times include ventilation system cleaning, or more commonly known as duct cleaning. Some homes don’t require this type of maintenance more than every five to ten years – perhaps longer. Unless there are unusually high levels of dust, allergens, or contaminants in the air, most ventilation systems can remain clean for several years.

Of course, you can turn all of your maintenance tasks over to a heating and cooling contractor – and have the most peace of mind.

Things You Should Have Inspected in Folsom

Friday, September 30th, 2011

Life would be great in Folsom if we could just depend on things to work and last without requiring any sort maintenance or upkeep. Unfortunately, that is not the case. As good as modern manufacturing and engineering are, our devices, appliances and machines still need attention in order to stay in peak condition.

The Body Is a Machine

To illustrate this, think about the human body. We put a lot of wear and tear on ourselves, which can lead to minor illnesses, injuries and the like, especially when combined with the effects of aging. One way we attempt to stay ahead of the game is to get an annual physical. Once a year, we pay a visit to our doctor to make sure everything is in tip top shape. He checks everything out, lets us know what’s going on, helps us treat anything that may be acting up and then off we go, ready to go for another year.

And So Is Your Furnace!

Likewise, your furnace needs annual attention as well. Although newer electrical furnaces can go up to three years without regular maintenance, gas and oil models should be inspected every year, as should older systems. During an annual inspection, an HVAC professional will:

  • Clean out fuel lines, keeping every flowing freely and efficiently.
  • Check for parts that are wearing out or need to be replaced.
  • Clean and inspect the heating ductwork as well as the vents.

These simple and routine maintenance tasks can extend the life of your furnace by years, keeping your home warm and your heating costs low.

The Best Time for Inspection

The best time to get your furnace inspected is in the late summer to fall months. Although you may still be trying to squeeze every bit of enjoyment from those last warm days, the cold weather comes not far behind, and you will want your furnace ready when that happens. A fall inspection ensures that your furnace will be all set when those temperatures start to drop, so your family won’t have to tolerate any chilly nights.

Annual maintenance is important for health and longevity, both for you and your furnace. You can even schedule your physical and your furnace inspection around the same time so you don’t forget. Make an appointment for your car while you’re at it, too. That makes three things you won’t have to worry about during those cold winter months.
