Why are Commercial HVAC Systems Modular?

Friday, May 16th, 2014

Commercial HVAC systems usually appear on the roof of the buildings they cool, and differ in numerous ways from residential air conditioning systems. Here in Woodbury, commercial HVAC systems are a common sight, and you may have noticed that they’re modular in nature, with multiple commercial units in place on the roof of just a single building. Why are commercial HVAC systems modular? The answer says a lot about why they differ from residential systems.

Every air conditioning unit it built to handle a certain power load. If it ever exceeds that power load, it will labor to do its job and may damage key components in the process. In residential homes hat’s not usually much of a factor. You measure the square footage, account for things like insulation and sun exposure, and install a single unit capable of handling the entire building. But that’s just not practical with business spaces. Office space may not be filled all the time and old tenant leave and new ones take their place. A prudent office manage doesn’t want to cool space that no one’s using, but if you have just a single air conditioning unit, you won’t have a choice. In addition, some businesses may need more cooling power than others; for example, if they have a large number of computer hard drives that need to be kept cool at all times. That speaks to the same thing: businesses need flexibility in their power load if they intend to cool the air effectively.

Modular systems provide that. In cases when you need more power, you can simply add another unit without having to replace the entire system. And if you need less power, you can just shut one of or remove it just as easily. Modular units also make it easier to conduct repairs without cutting off air to the entire building; no small concern if you want your customers and employees to be comfortable.

Air Conditioning Question: What Is Refrigerant?

Friday, April 18th, 2014

In order for an air conditioner (as well as a heat pump and a refrigerator) to function, it requires a chemical mixture called refrigerant. Without refrigerant pumped through the AC, starting from the compressor and then moving to the outdoor and indoor coils, no heat exchange would take place, and the air conditioning system would act as nothing more than a large set of fans.

We’ll explain in more detail what refrigerant is and how it works. When you need more information about your air conditioning in Woodbury, NJ because of a repair need or if you are considering installing a replacement, look to SPS Mechanical Inc. and our skilled staff.

Refrigerant basics

Refrigerant refers to any chemical that carries out heat exchange: that is, movement of heat from one place to another. To work efficiently, refrigerant must go through a quick phase transition, the change between liquid and gas and back again. Refrigerant absorbs heat in the evaporation stage, and then releases it during the condensation stage. During normal operation, refrigerant does not dissipate as it changes phase.

Early refrigerants were made of toxic, acidic, or combustible material, such as ammonia. Not until the invention of Freon (a trademarked name for a number of refrigerant blends) did safe refrigerants allow ACs to enter regular home use.

For many years, the most common refrigerant blend found in air conditioners was R-22, a hydrochlorofluorocarbon blend. Because of the negative effect that hydrochlorofluorocarbons have on the earth’s ozone layer, the U.S. started a phase out of R-22 during the 21st century, with complete disuse set for 2020. The current common blend for residential air conditioners is R-410A, a mixture of two earlier blends often trademarked as Puron. R-410A has no ozone-depleting properties. Its use has also increased the efficiency of air conditioners, causing a general reduction in power consumption that compensates for R-410A’s global warming potential.

Leave refrigerants to the professionals

Refrigerant in an air conditioner is set at a specific charge (level), and if that level drops because of leaks, it requires technicians to recharge it. You need to leave such repairs to trained HVAC specialists, who know how to seal leaks, and put in the right amount of new refrigerant. Over- or undercharging refrigerant will damage the system.

If you have troubles with your air conditioning in Woodbury, NJ because of leaking refrigerant, call SPS Mechanical Inc., any time of the day or night, for the service that will take care of the problem and restore the cool air to your home.

Heating Tip: How to Prevent Energy Loss

Monday, November 18th, 2013

You need a good heating system to keep your home cozy home during our chilly winters, but often come with high energy bills to boot. We’ve come to expect that as the price of staying warm, but it doesn’t have to be that way. The key is to keep your heater as efficient as possible, while ensuring that your home has the ability to retain the heat generated. Here are a few tips on how to prevent energy loss.

Schedule a maintenance session with a trained professional to clean your heating system. Over the summer, dust and dirt can build up on the interior components, and fittings can become loose. This can result in a nasty surprise when you need the heater to function and it cuts out. A technician can clean the dirt away, tighten any loose connections, and spot any larger issues in need of addressing. This will help prevent larger repairs, as well as ensuring that your heater is functioning at maximum efficiency.

The next step is to look after your home.  If your home is leaky or poorly insulated, you’re going to lose energy just when you need it the most. You can prevent that by spotting and sealing any leaks around your doors and windows. If you can, see about adding more insulation as well. It will help keep the heat inside (and cold inside in the summertime, just for good measure).

For more ideas on how to prevent energy loss in your home, or to schedule a maintenance session with your furnace, contact the Woodbury, NJ heating pros at SPS Mechanical to help. We deal with heating systems of all varieties and can handle maintenance, repair and installation services with courtesy and professionalism. Give us a call to schedule an appointment today.

Heating Guide: How Radiant Heating Works

Monday, October 14th, 2013

You may have heard the term “radiant heat” talked about in reference to a home heating system. It’s one of two basic types of home heating, the other being “forced air” systems which push warm air throughout your home to raise the temperature. Radiant heating tends to be a more effective and cost-friendly way to keep your house cozy on a cold day. In towns like Woodbury, NJ, heating systems need to be effective in order to keep winter at bay without breaking the bank, making radiant heating an attractive option for homeowners. Here’s how radiant heating works.

It starts with the floor. A radiant heating system places a series of tubes or coils beneath the floorboards. Which one? That depends on the type of radiant heating system. Hydronic systems pump water through tubes; a furnace or boiler then heats the water to warm the tubes. In the case of electric systems, the tubes are replaced by electric coils protected within a heat-conducting mat.

Regardless of the system, the results are the same. The coils/tubes warm up the floor, which in turn warms up other objects in the room (including people). The heat is mild enough to let you walk around barefoot without pain, and it’s safe on furniture and curtains as well. Because it starts at the floor, very little of the heat escapes through the ceiling, increasing overall efficiency and lowering your heating costs as a result. Radiant heating isn’t subjected to the vagaries of air flow, allowing the whole space to be heated evenly and preventing the circulation of dust and similar particles from blowing air. Zone controls allow you to tailor a radiant heating system to heat only those areas that you want, further saving you money.

The specifics of installing a radiant system depend on the particulars of your house, but you can consult a trained professional on how radiant heating works and what version works best for you. For Woodbury, NJ heating issues, talk to SPS Mechanical. We serve all of Southern New Jersey, and our qualified experts are available 24 hours day. Call us to set up an appointment today!

Ask a Plumber: What’s Wrong with My Septic System?

Monday, July 8th, 2013

If you have a septic system on your property that is causing you problems, there are a huge variety of things that could be causing the issue. Usually, you’ll need to call a plumber if you’re having problems with your septic system. At SPS Mechanical, we offer 24/7 emergency plumbing service for all different types of issues including septic repair. Make sure you take a look at some of the things that could be causing your septic system to not work well.

  • Septic tank full – Usually, depending on how many people are in your household, septic systems need to be serviced and emptied about once per year. If you haven’t had this service performed regularly it could be causing your toilets and drains to back-up.
  • Leech field or soakway problems – Another very common problem with septic system is the leech field (also called the soakway). If you hear gurgling sounds from your drains and toilets, if your toilets are backed up, or if you try to drain your bathtub and it fills up your toilet or sink it could mean that your leech field is clogged. Other indications of this could be foul odors around your home’s drains or indentations in your yard where the leech field is.
  • Leech field too deep – Another very serious issue could be that your leech field or soakway is buried too deep. If your leech field is too deep there won’t be enough oxygen to allow the growth of the proper bacteria cultures that feed on the waste. It could allow other type of bacteria to grow which would clog the pipes with mold and slime.

When you need a Sewell, NJ plumber just call the experts at SPS Mechanical. We’re available 24/7 for plumbing emergencies because we know that things don’t always break down when it’s convenient. Give us a call today to talk with one of our friendly plumbers.

Air Conditioning Repair: How Damaged Coils Affect Operation

Monday, May 27th, 2013

Our air conditioning systems are complex, comprising various components, connections, and mechanisms, all of which work cooperatively to provide respite from the heat outside during the cooling season. As you probably already know, one of the major components of your system is the coils. The coils in the outside unit are known as the condenser; those in the indoor unit known as the evaporator. While they are both coils, they have very different—some might say opposite—functions. Refrigerant circulates through these coils, pressurized as they are by the compressor pump. The refrigerant condenses in the condenser coil by dissipating heat, and evaporates in the evaporator coil by cooling air, hence their respective names. But when the coils become damaged, they can dramatically reduce the ability of your air conditioning system to function properly. For air conditioning repair in Woodbury, NJ, call the experts at SPS Mechanical today!

Let’s take a look at how damage coils affect operation:

  • Evaporator coil: Your evaporator coil is responsible for cooling the air that is then sent throughout your ductwork. It is usually shaped like a pyramid with the bottom open, so that any condensed water that accumulates in the process can drip into the condensate pan. If it’s covered in dust or debris, then the coils become much less effective in cooling the air and absorbing the heat its heat. If they are damaged, it can lead to improper dehumidification and frozen coils.
  • Condenser coil: Your condenser coils typically wrap the enclosure of the outdoor unit, to maximize heat dissipation, which is also assisted by a vertical exhaust fan. Its purpose, as already mentioned, is to disperse the heat of the gas refrigerant, which has been highly pressurized and heated by the compressor. Because the temperature of the refrigerant is hotter than the outside air, the heat quickly dissipates. If this process is disturbed by damage the coils, this dissipation cannot take place. This can result in warm air coming through your ducts.

These are just a few of the issues resulting from damaged coils. For expert air conditioning repair in Woodbury, NJ, call SPS Mechanical today!

Air Conditioning Repair Tip: Common User Errors

Monday, April 8th, 2013

Whether you’ve just bought your air conditioner or have ran it for years, you may not realize that it requires a certain amount of care to run smoothly and to minimize repairs. In short, there are some common user errors that many homeowners do that may have adverse effects on their systems. While we certainly don’t expect you to know the details of the air conditioner’s operation, a little bit of know-how goes a long way towards extending the life of your system and improving the comfort of your home during the summer months. For more information about air conditioning repair in Swedesboro, NJ, call SPS Mechanical today!

  • Forgot to change the air filter: Regularly changing your air filter is one of the things that even the least technicial of us can learn to do. It’s important to the integrity of our system. While the air filter is there to prevent the passage of pollutants and dust from entering your living space, when it becomes dirty or clogged, it can actually begin to impede airflow, which can result in damage to other parts of the system, in addition to inadequate cooling.
  • Bigger is not better? No, it’s not. Your air conditioner needs to be appropriately sized to your home. This depends not only on the volume of air in your living space, but also on the quality of your insulation and the orientation of your home with respect to the sun. Choosing the largest possible system with the hope that it will easily handle your cooling needs may only lead to excessive cold air and frequent short cycling, which can dramatically reduce your energy-efficiency. You need a professionally sized system that will maximize your efficiency without sacrificing performance.
  • Maintenance is unnecessary: You might think that if your AC is under 5 years old, then it doesn’t need anything. Nothing could be further from the truth. This is a common user error. Routine maintenance and cleaning by a professional is the best way to ensure that your cooling system operates effectively and efficiently for years to come. Without it, however, the efficiency of your AC can dramatically depreciate.

These are just a few of the mistakes that can lead to problems with your air conditioning. If you have any questions or concerns, be sure to ask a certified professional. For air conditioning repair in Swedesboro, NJ, call SPS Mechanical today!

3 Common Water Heater Problems

Monday, February 18th, 2013

The access to clean, dependable hot water in our homes is something that many of us cannot imagine living without. Unfortunately, many homeowners will open their hot water faucets someday only to discover that the water they rely on so much is not available, or at least not of the quality they are accustomed to. Like any other mechanical device, your hot water heater requires a professional installation and regular maintenance service to operate properly. Even these necessary steps cannot always prevent problems with your hot water heater in Woodbury, NJ, though. Here are 3 of the most common water heater problems we encounter, and some possible causes. Remember, when you need hot water heater services in Woodbury, NJ, call SPS Mechanical.

  • We receive many service calls about pilot lights that frequently go out. There are a number of causes for this, and they range in seriousness. Obviously if you use natural gas to heat your hot water a pilot light that will not stay lit is cause for concern. Call for professional service immediately. The cause may be something serious such as a gas leak somewhere between the supply and the hot water heater. It could also be a faulty safety device, such as the thermocouple. A thermocouple uses a mercury sensor to stem the flow of gas if it does not detect sufficient heat for combustion. If it malfunctions it will cause the gas to cut off, causing the pilot light to go out.
  • Another common problem with water heaters is a pretty obvious one; no hot water. Again, there are multiple factors that may cause this problem. If you use an electric hot water heater it is possible that the circuit it operates on tripped. With the flip of a switch you may have your hot water back. If you use natural gas, there may be a problem with the gas supply or burner beneath the water heater. Only a professional can tell you for sure.
  • If you use a tank hot water heater you may discover that the storage tank is leaking. Unfortunately, there is really only one solution here; it is time to replace the storage tank. Make the investment worthwhile by getting a well-insulated and efficient new model.

Whatever problems you have with your hot water heater in Woodbury, NJ, SPS Mechanical has the solution. Let us help keep the hot water flowing in your home. Call today to schedule service.
