What Is a High Efficiency Air Filter?

February 27th, 2015 by Michael Henderson

Having good indoor air quality is important to your year-round, overall comfort. One way to help ensure that your indoor air quality is at the level you need and want it to be is by using a high efficiency air filter, also known as a HEPA filter, in your Springfield, PA, home. However, before installing any kind of HEPA filter into your HVAC system, it’s very important to consult with an indoor air quality expert. This is because the media in a HEPA filter can be so strong that it significantly reduces the air flow in your HVAC system, which can lead to operational problems. Wm. Henderson Plumbing & Heating Inc., has been providing indoor air quality services for almost 40 years, and our IAQ specialists can help you determine which HEPA filter is best for your home. Call us today!


MERV and HEPA are intertwined because MERV, which stands for minimum efficiency reporting value, tells consumers how effective a particular air filter is. The MERV scale runs from 1 to 20, and to qualify as a HEPA filter, the filter has to have a minimum MERV of 13 and these other qualifications:

  • The filter must be able to trap particles as small as 3 microns (human hair is typically 70-100 microns in size)
  • The filter must be tested according to US Military standard 282, and each tested filter must be individually certified and labeled with its test results
  • The filter must have a minimum efficiency rating of 99.97%


What Makes a HEPA Filter Different?

One of the main differences between HEPA mechanical filters and those that aren’t HEPA is the capture capability. HEPA filters are made to capture a great many particles, including some biological contaminants. This is because of how they are made, which brings us to a second difference between HEPA filters and non-HEPA filters. The media of HEPA filters is made with a glass-fiber type of paper that is highly effective at capturing particles. This paper is folded into small V-shaped pleats that are held firmly in place by aluminum separators between each pleat. Pleating makes it difficult for particles to continue passing through filter media, which is part of the reason why HEPA filters are so effective.

As mentioned above, HEPA filters should only be installed into your HVAC system after working with a qualified specialist. If you feel a high efficiency air filter in Springfield, PA is for you, call the indoor air quality experts at Wm. Henderson Plumbing & Heating Inc., today!

Signs Your Commercial Plumbing Needs Replacement

February 20th, 2015 by Michael Henderson

No business owner wants to think about having to replace plumbing, but as a business owner, you could be at serious risk of rendering your commercial space unusable if you don’t make needed plumbing replacement or repairs. Commercial plumbing systems are long and complex, so it’s important to hire experts with experience in commercial plumbing replacement for your Bryn Mawr business. Wm. Henderson Plumbing & Heating Inc., has been helping commercial customers with their plumbing needs since 1977, so if you are experiencing problems with your commercial plumbing, call us today!

Seeing the Signs

Here are some of the more common signs that you may need to replace the plumbing in your commercial space:

Discolored Water

Discolored water is often a sign that rust or excessive dirt is inside your piping. Typically discoloration will be brown or yellow, but any kind of discoloration means a problem has developed with your system and professional assistance is required.

Recurring or Multiple Leaks

If you have a leak that keeps coming back, or have been dealing with multiple leaks developing throughout your system, it’s time to have a professional assess the situation as it may be time to replace damaged piping.

Flaking or Dimpling of Metal Pipes

If you can see visible flaking or dimpling of your commercial space’s piping, there is excessive corrosion both in- and outside the piping. Excessive corrosion in any plumbing system is a serious problem and should be addressed immediately.

Development of Mold

Mold needs moisture to grow, so if you are seeing a lot of mold in a particular area or smelling a strong odor of mold, it is likely you have a leak on your hands; as such, you may need to replace the piping that is the origination of the leak, depending on the level of damage.

Water Pressure Problems

Water pressure is necessary for your plumbing to work, but if the pressure is too high or too low, a number of different types of problems can develop.

For your business space to be operable, it needs proper water function. If you are seeing the signs that it may be time for commercial plumbing replacement in Bryn Mawr, call the commercial plumbing experts you can count on: Wm. Henderson Plumbing & Heating Inc.

Some of the Unusual Movies Released for Valentine’s Day

February 14th, 2015 by Michael Henderson

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

  • Dracula (1931): Yes, this Halloween perennial and the start of Universal Studio’s Classic Monsters actually came out on Valentine’s Day! But perhaps this makes some sense, as the Dracula legend has often received a “doomed lover” approach in the many years since Bela Lugosi made the aristocratic vampire a screen icon.
  • The Silence of the Lambs (1991): Does any film seem less appropriate for Valentine’s Day than this unnerving and sometimes very violent psychological thriller? What’s even more astonishing than the film’s release date is that The Silence of the Lambs eventually nabbed the Oscar for Best Picture, an almost unheard of occurrence for a movie released so early in the year.
  • Daredevil (2003): This Marvel comic adaptation featuring Ben Affleck as a blind superhero does contain a romantic subplot, but the stronger connection to Valentine’s Day may just be that Daredevil wears a bright red costume.
  • A Good Day to Die Hard (2013): The least successful of the Die Hard film franchise, this is an excellent example of a studio dropping a film into a weekend where it doesn’t fit in the hopes that it works as counter-programming. (It didn’t.)
  • Wayne’s World (1992): Now here is an example of counter-programming that clicked with audiences. This comedy based on a Saturday Night Live sketch turned into one of that year’s biggest hits and spawned a sequel.

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at WM Henderson Inc. hopes you and your loved ones have a wonderful weekend.

How Can Drain Cleaning Help Prevent Drain Repair in Ardmore?

February 5th, 2015 by Michael Henderson

While very few people truly enjoy cleaning the bathroom, you try to keep it as clean as possible for your guests and your own health and comfort. But while you may scrub the toilet, tub, and sinks diligently, there’s still one portion you may always miss, the drains. The drain opening may be shiny and spotless, but the inside of the drains in the bathroom and the kitchen may be coated with grease, “sludge,” and a bit of debris here and there. This increases the potential for drain clogs, which can inconvenience you in some major ways.

Some people attempt drain cleaning on their own as a form of clog removal or drain maintenance by pouring drain cleaning liquids down the drain. These are generally found at most hardware shops and even many grocery stores, but beware: these are some of the most toxic chemicals available for consumers to purchase in stores. Furthermore, they can actually damage the pipes, and most don’t clear clogs completely.

Professional drain cleaning uses zero toxic chemicals, so that no damage is accrued. Instead, they use any of several tools including drain augers that reach deep into the drain pipes and latch onto clogs in order to pull them up through the drain. Or, a technician may use a different attachment to break up clogs and send them into the sewer. In some cases, technicians may have to use high-pressure hoses to blast water into the pipes and remove any stuck-on sludge.

Some experts even use video pipes to inspect deep within the pipes and make sure that clogs are completely taken care of and that no further problems may lead to clogging in the future. Drain cleaning is a service which can vastly improve the condition of your plumbing system, to the point that you’re unlikely to run into any major drain clogs for the rest of the year.

Call Wm. Henderson Plumbing & Heating Inc. today!

When you schedule drain cleaning in Ardmore with one of our skilled professionals, you’ll get a thorough inspection and quality cleaning service with some of the best tools in the industry for maintaining drains.

Will Drain Cleaning Get Rid of Odors in My Drains?

January 30th, 2015 by Michael Henderson

It’s that unidentifiable smell around your sink. You clean the sink, wash dirty dishes, and yet, it hangs there. You finally bend down to take a good whiff, and realize that the smell permeating your nose is coming from your kitchen drain. What do you do now?

Smells from your drains are unpleasant but they aren’t permanent. Unless the source of the smell is from a sewer or septic problem, which most times it isn’t, the smells in your drain are caused by build-up that needs to be removed. So what’s the best way to remove the build-up? Schedule a drain cleaning appointment for your home in Newtown Square.

What Is Drain Cleaning?

Drain cleaning is the process a professional plumber uses to carefully remove build-up from the inside of your pipes. Typical build-up culprits are fats, oils and grease (FOG), soap scum, food particles and human hair, but many other things can get stuck in your drains. Food and FOG tend to create the most issues with foul smells because they can spoil, but slow-draining wastewater can cause odors, too. Removing build-up and thoroughly cleaning out the drain not only eliminates the odors, it has other benefits, too.

Benefits of Drain Cleaning

Here are some other benefits you can see from a professional drain cleaning:

  • Removal without damage – professionals know how to properly manage the tools used for drain cleaning, which ensures that they’ll get the gunk out of your drains without breaking anything.
  • No more slow drains – if you were seeing slow water drainage in a tub or sink, you won’t after a professional drain cleaning. Excessive build-up in your pipes can cause slow draining or clogging, so removing it allows your wastewater to flow freely.
  • Prevent clogs – removing build-up gets you ahead of potential clog development.
  • Helps maintain your plumbing – drain cleaning keeps your plumbing in good working order.

Wondering where those bad smells may be coming from? If you find they are from your drain, don’t wait for a clog;

Why You Shouldn’t Wait to Repair Your Commercial Rooftop Unit

January 29th, 2015 by Michael Henderson

As the manager of a large commercial property, chances are that you’re quite busy. When a customer, client, employee, and/or tenant informs you of trouble with the heating in the building, it may seem as though you can wait a little while for repairs. After all, the heat is still working to some level, so the temperatures in your building are bearable. While it’s sometimes tempting to wait for commercial heating repairs until they fit a little bit more soundly into your monthly budget, this type of thinking is potentially harmful to your system and to the people who rely on you commercial rooftop unit for heating and AC.

Rooftop units are the most common HVAC (heating, ventilation, and air conditioning) systems installed on commercial buildings today because they offer many benefits for property owners and employees alike. Rooftop units have a cabinet which encloses every portion of your heating and air conditioning system. When a technician visits the property to maintain or repair the unit, this is beneficial because they stay out of your way and the repair moves a bit faster than it may have otherwise because all of the parts are centrally located. As long as your unit is professionally maintained twice a year, you should run into very little unexpected trouble over time.

When someone in your building notices that there is a potential problem, it may be that you only have a minor repair need. Sometimes, heating is reduced because of a dirty burner or a bent fan blade. But this small problem can develop into something much worse. All of the other components have to work harder, and this extra strain on the system can lead to overworked parts and an eventual breakdown. Why wait for a sudden failure when you can pay less for a repair today? The people in your building count on you to keep everything running as needed, and it’s vital that you keep everyone in the property comfortable for increased productivity and to keep customers and clients coming back.

For Commercial Rooftop Unit Repair call the expert team at Wm. Henderson Plumbing & Heating Inc. today.

When Is the Right Time for Heating Maintenance?

January 22nd, 2015 by Michael Henderson

When it comes to maintaining your heating system, most people don’t think of scheduling maintenance in the middle of winter. But if your system hasn’t been maintained in twelve months or more, any time is the right time to schedule a heating maintenance appointment in Drexel. While most people like to schedule maintenance for their heaters in the fall, the bigger priority is to schedule the appointment, not wait for the perfect time of year to do it. The experts at Wm. Henderson Plumbing & Heating Inc., are available for maintenance, repairs and even replacement, so if it’s been a while since we’ve seen your heating system, call us today.

Why Is Maintenance Important?

Your heater works really hard all winter to provide your home with heat, and then it sits for several months and accumulates dirt and dust. Then, it turns back on again and has to work with last year’s wear and tear and this year’s dirt and dust: it’s not a good combination for your or your heater. During a maintenance appointment, one of the main tasks is to thoroughly inspect your system for wear and tear. If any is found, like frayed wiring or a worn fan belt, these things are repaired. Dust and dirt can make operation of components difficult, so another important task performed during a maintenance appointment is cleaning. Performance and safety tests are run to ensure the system is operating at the efficiency level it should be and that it does so safely. Other benefits include:

  • Better energy efficiency – a system that is clean, adjusted and properly lubricated is one that runs well and can achieve the energy efficiency it’s supposed to.
  • Better comfort – there’s no worry that your heater can’t reach your set temperature because it has gotten a full tune-up and is ready to go.
  • Lubrication – depending on your heating system there may be multiple moving parts that need lubrication in order to work correctly; during maintenance, all parts that need lubrication are serviced.
  • Prevents repair – the thorough inspection your system receives allows the technician to detect any developing or existing problems, which helps get you ahead of repair problems.

Fall is a great time to schedule repair, but maintenance is an ongoing thing.

If your heating system in Drexel hasn’t had maintenance yet this season, contact Wm. Henderson Plumbing & Heating Inc., today.

Problems that May Occur with a Commercial Boiler

January 15th, 2015 by Michael Henderson

Commercial boilers are powerful heating systems, with the ability to keep an entire office building warm no matter what the outdoor temperature. Boilers are built tough because they often handle a large heating load. Even though these units are meant to last for many years, there’s always a chance that a problem can surface with any electro-mechanical system. When you notice any of the following problems with your commercial boiler, it’s important to call for commercial HVAC repair in Wynnewood as soon as possible.

  • Little Heating: If you’re not getting the heating power you desire from your commercial boiler, it can mean a major problem, or the repair may be as simple as cleaning off a few parts. Dirty burners can cause limited heating, but so can a major repair need like a leak or an imbalance in pressure. Even if the lack of heat seems bearable, you should call an expert for service as soon as possible to keep the issue from worsening.
  • Uneven Heating in One Area: If there is not enough heating in one office, a single floor, or any particular area of the building, it’s likely a problem with the zone control system. A technician should adjust the settings of any zone according to that floor’s particular needs, but sometimes the structure of the room requires higher or lower settings for whatever reason. If, for example, an office on the second floor has carpeting, while other areas have tile or hardwood floors, the settings may need to be adjusted so that more heat moves into that room only.
  • Leaks: This problem is rare, but it’s definitely one to look out for. If you notice water leaks from your boiler, it indicates a pretty serious problem that should be addressed immediately. This could have to do with the expansion tank, the pressure relief valve, or it could be a sign of rust and corrosion, an unfortunate possibility with older boilers that almost always results in replacement.

We have enough experience to diagnose and repair any heating problem that interferes with the way you do business.

Call Wm. Henderson Plumbing & Heating Inc. for boiler maintenance to help prevent problems such as these from occurring, or to schedule commercial HVAC repair in Wynnewood.

Isn’t the City Responsible for Replacing the Sewer Line?

January 8th, 2015 by Michael Henderson

It’s one of those home repair nightmares you hope you don’t have to deal with: sewer line replacement. Not only is it serious work, it can be fairly costly. But as the homeowner, are you liable for the replacement of a faulty sewer line? Most of the time, yes, you are. Utility company responsibility typically ends once the lateral or side sewer line begins on a particular property, but to be sure about your town’s guidelines, it’s important to make a call to your area’s Public Works Department or Sewer Department. Should you need sewer replacement in Broomall, call the experts you can count on: Wm. Henderson Plumbing & Heating Inc.

So how do you know if you are having problems with your sewer line? Here are some telltale signs:

  • Slow drainage/no flushing – the sewer line serves as the exit pipe for all the wastewater from your home. If there is a break, you may see slow drainage from all the drains in your home or your toilet may stop flushing.
  • Sewer odor – a broken sewer line can release foul odors, which you may smell in the air around your home or even coming from drains.
  • Yard puddles – as the wastewater escapes from your sewer line, it makes its way to the surface and can create sogginess and/or puddles in your yard.
  • Gurgling from drains and toilets – if you find that toilets and drains are gurgling after using a water appliance like a dishwasher, this can be indicative of a clog or break in the sewer line.

Causes of Sewer Line Breaks

There are a number of reasons your sewer line can break:

  • Tree roots – one of the most common reasons a sewer line breaks is from tree roots. Tree roots are very strong and can crush a sewer pipe, particularly if it is an aging pipe.
  • Paper hygiene products – maxi pads, tampons, diapers – all of these products create large clogs that can cause the piping to break because they do not break down. Disposing of paper hygiene products in your garbage can save you money in the long run.
  • Age – sewer lines are durable, but they do not last forever. If you live in or are purchasing an older home, you may want to ask about the sewer line to find out how old the piping is.

A sewer line break is a serious repair and should only be handled by experts who understand and know the work.

If you suspect you may have a broken sewer line, call Wm. Henderson Plumbing & Heating Inc., today to ensure that the issue is properly addressed. 

The Importance of Replacing an Older Chimney Liner

January 2nd, 2015 by Michael Henderson

The chimney of your home helps to vent combustion gases to the outside so that they do not enter the house and contaminate the air that you breathe. But the material used to construct masonry chimneys is generally ineffective in doing so alone. Most local fire codes mandate the use of chimney liners in homes in order to provide proper ventilation and protect the chimney construction materials as well as your safety. Additionally, if you have an older liner, a technician may recommend replacement upon inspection.

Older chimney liners may develop cracks and holes that allow the masonry chimney to wear down, or worse. A masonry chimney may wear down rather quickly as combustion materials cause it to corrode, leading to costly home renovations. But a more dangerous possibility is if these combustion fuels leak into your home, leading to carbon monoxide poisoning and other potential health risks. Furthermore, an unlined chimney or a worn down chimney liner can be a major fire hazard.

This is a more likely possibility if you have an older tile liner. Ceramic tiles are perhaps the most popular form of chimney liners used in existing homes, but are not recommended for new installation. That’s because ceramic tile is not effective at absorbing heat and may not be able to contain and distribute it throughout the chimney. This causes the tile to crack and split apart. With proper maintenance, it may be possible to prevent this or detect problems early on, but many installers prefer a more durable chimney liner made of aluminum or stainless steel.

Another possible reason to replace a chimney liner is if it is the wrong size for your home. Chimney liners must be properly sized to the heating system and your home in order to make sure gases vent efficiently and completely. The benefit of a well-built chimney liner is that it can meet any venting needs, so long as a technician makes plenty of measurements to size it for your home. If a technician determines your current system is not properly venting gases, they’ll likely recommend a new one. Furthermore, a new one may be necessary if you upgrade your heating system in any way and the venting requirements change.

New stainless steel or aluminum chimney liners in Havertown installed by Wm. Henderson Plumbing & Heating Inc. can help to ensure your safety and comfort at home for many years to come. Give us a call today!
