Why Should I Schedule a Ductwork Inspection?

Wednesday, August 27th, 2014

Without your ductwork, there is no delivery of cool (or warm) air to your home. And with faulty ductwork, the air delivery can be compromised. Because your ductwork lives behind walls, in attics and through crawlspaces, it can be easy to forget about it. Unfortunately, like other parts of your air conditioning system, your ductwork can develop holes and cracks, and sections can become damaged and disconnect. One of the best ways to avoid large problems with your ductwork is to schedule an annual inspection with your annual maintenance appointment. And should you need duct cleanings service for your Mullica Hill property, SPS Mechanical, Inc., has the professionals to get it done.

What Is a Ductwork Inspection?

A ductwork inspection can be a thorough visual inspection, in which camera equipment is used to inspect the entirety of your ductwork for problems; an inspection can also consist of testing your ductwork for leaks, which is a much more precise process that determines exactly what ducts may be leaking air.

How Is Duct Testing Done?

There are two ways in which duct testing can be done: the pressurized subtraction method and the duct testing method. With the pressurized subtraction method, a high-powered fan is set up in a doorway and connected to pressure gauges. Your entire space is then pressurized with the fan, first with the ducts open, then with the ducts closed, to help determine where air leaks may exist.

The duct testing method uses a calibrated fan to gently pressurize the ducts. While it does this, gauges measure the airflow through the ducts to determine if there are leaks, and if so, measures the leakage. Instead of a large, high-powered fan, the duct testing method utilizes a smaller portable fan with calibrated digital pressure gauges that connect to the blower of your indoor air handler. All ducts are sealed for the test and the fan is turned on to pressurize the system. The gauges tell what the pressure is, and if the pressure is found to be outside acceptable limits, repair and/or sealing of the ducts will most likely be recommended.

Why Schedule a Ductwork Inspection?

Your ductwork is an integral part of your air conditioning system. Problems from your ductwork can decrease energy efficiency and indoor air quality, as well as stress your AC system.

What Are Blower Doors and What Are They Used For?

Wednesday, August 20th, 2014

How energy-efficient is your home? You may not know it, but your home might contain numerous air leaks where heat escapes during cold weather and enters during warm weather. This places a strain on your HVAC system and leads to discomfort. Those same air leaks can also bring in moisture and lower your indoor air quality.

The best way to evaluate your home’s airtightness is to schedule an energy audit. An audit, also called a home performance evaluation, will systematically locate where your home is losing energy and find the best ways to seal and insulate it so you’ll save money and protect your indoor environment.

To find professionals who handle energy audits in Glassboro, NJ, contact the team at SPS Mechanical Inc. We specialize in energy-saving solutions for homes.

The key tool for an energy audit: the blower door

To evaluate the airtightness of a home, auditors use a device called a blower door. The standard blower door mounts within the frame of an open door, sealing completely across the aperture so there are no leaks around it. Within the blower door is a large variable speed fan and a pressure monitor called a manometer. During an energy audit, the technicians attach a blower door to the front door of a house. They then make sure that all other doors and windows throughout the house are shut. The blower door fan activates, and it draws air from inside the home to depressurize it; the manometer measures the difference in pressure.

Once the blower door has lowered the pressure inside the house, outside air will rush in through any opening, such as gaps in building material or insulation, and around poorly sealing windows and doors. The auditors move throughout the house and use smoke pencils to detect where air is rushing to enter air leaks. After a blower door test, the auditors will have a good idea of where a home lacks integrity in its heat sealing, and they can start to investigate specific areas.

Energy audits consist of more than the blower door test: excellent auditors will perform an extensive walk-through of the building to note specific points of energy loss and gain. They’ll test the HVAC system and the sealing along the ventilation. They’ll see if all your major appliances (laundry machines, refrigerator) are working at their most efficient. Once they’re done, they will report to you with a list of where your home could improve its efficiency and suggestions on what you can do.

We suggest that everyone have an energy audit done for their home at some point. If you feel that you are paying more on your utility bills than you should, call SPS Mechanical Inc. and ask about our services for energy audits in Glassboro, NJ. We use blower doors and other advanced technology to give homes thorough performance evaluations.

How Professionals Perform Duct Cleaning

Wednesday, August 13th, 2014

In order for your air conditioning and forced-air heating system to work their best, they need to have clean “lungs,” i.e. air ducts. Even a thin layer of dust along the inside of ductwork can create friction against the movement of air that will cause your comfort system to start to work harder. This increased strain will lead to higher utility bills and greater wear and tear. Your ducts will probably need cleaning every other year, although sometimes more frequently depending on how much contamination enters the ductwork.

To clean ducts requires the work of specialists with professional-grade equipment. You cannot do the work on your own using a vacuum with a long hose. Call a company like SPS Mechanical Inc. to handle this job. We will not only take care of your duct cleaning in Cherry Hill, NJ, we can perform duct testing and inspections to see that your ducts aren’t suffering from leaks or defects that will increase the contamination inside them.

The Professional Method of Duct Cleaning

The way that trained duct cleaners do their job is through the use of power vacuums and agitation equipment. Sometimes, they will also use non-toxic sanitizers and deodorizers.

The main part of duct cleaning involves changing the pressure throughout the ventilation system. The technicians seal off all the vents in the house, then attach a large power vacuum to the duct that exits from the indoor air conditioner/heater cabinet. The vacuum places the ventilation under “negative pressure” that causes the pollutants like dust, dander, dirt, and other debris to loosen from the ductwork walls, making them easier for the vacuum to suction up.

To attack dirt in specific areas, the duct cleaners will open up the registers and insert long vacuum hoses with rotary brushes attached. The action of these brushes dislodges particles from the duct walls without damaging the ductwork material and allows for easy removal.

Once the technicians have finished a thorough cleaning (which should take only a few hours and offer minimal disruption to your daily activities), they will reconnect the heater and air conditioner and reactivate the HVAC system.

Duct Cleaning is Beneficial for Household Health As Well

The cleaning job described above will not only help you maintain an efficient air conditioner and heater, but it will improve the indoor air quality of your home. Duct cleaning eliminates many particles that will trigger asthma and allergy attacks. If you live in a home with people who suffer from asthma and allergies, you need to make duct cleaning an important regular (probably annual) service. Significant contamination build-up will also begin to affect people without health conditions, and lead to a generally unpleasant environment.

SPS Mechanical Inc. offers top-quality duct cleaning service in Cherry Hill, NJ to see that you have a healthy HVAC system and healthy indoor air. Give us a call today to schedule your next service appointment.

Signs You Need Commercial HVAC Repairs

Thursday, August 7th, 2014

An air conditioning and heating system working at its best is an asset for a company. However, it’s easy to take the comfort for granted and assume the system will continue to operate at the height of efficiency without interruption. Considering the amount of work that a commercial HVAC system must perform year-round for a busy company, it shouldn’t come as a surprise that eventually it will encounter malfunctions that will require professional attention.

Here are a few signs to look for that will alert you to an HVAC system that is struggling because of a repair need. Call SPS Mechanical Inc. for professional technicians who can handle the work to restore your commercial HVAC in Glassboro, NJ. We also offer regular maintenance which will make sure that your business’ heating and cooling is never taken for granted and always receives the care it needs to keep running.

Indications of Repair Needs for Commercial Systems

  • Uneven heating or cooling: Always pay close attention to employees who have noticed hot or cold spots in the building. Your employees will be accustomed to steady temperatures, and they will quickly notice changes that lead to discomfort. Uneven heating/cooling is usually a sign that something has gone wrong with the thermostats or the dampers in the ventilation system, but it could also indicate that the actual air conditioner or heater is beginning to struggle and cannot send out conditioned air to all parts of the work space.
  • Skyrocketing power bills: As a business owner, you will keep close track of expenses. Should you notice an increase in your power bills that you cannot account for due to changes in work schedules, the issue may lie with an HVAC system that has started to work inefficiently due to malfunctions. It could be loss of refrigerant, strained motors, dust and dirt in the system, clogged filters, or general wear and tear due to lack of maintenance. Call for technicians to investigate.
  • Odd smells from the vents: Acrid and musty smells that start to permeate a building often come from the vents. This could indicate breaks in the ventilation system, or it could come from overheating engines or a compressor inside the heater or air conditioner. Don’t hesitate when these odors start, since a burnt-out compressor is one of the most expensive repairs an air conditioner or heat pump can need.
