Teaneck AC Tip: Keep Your Home Cool and Save Energy

May 7th, 2012

As the season of hot days and long evenings draws near, it is normal for questions to arise on how to keep your home cool and save energy.  In normal trains of thought, using your Teaneck air conditioning unit frequently would mean higher utility bills.  However, there are some things which are easy to do and can help keep any house cool without overuse of an air conditioner.

Easy Fixes Which Cool the House from the Heat of the Sun

  • Provide effective shade for east and west facing windows, including planting shade trees around the exterior of the house
  • Delay heat-generating activities until evening
  • Keep the house closed tight during the day so that unwanted heat and humidity do not enter the home
  • Ventilate at night with open windows and fans
  • Use ceiling fans or room fans to increase comfort levels with higher air conditioning thermostat settings
  • Seal and insulate all air conditioning ducts, and seal leaky windows with caulk or weather stripping
  • Install window shades, blinds, awnings, sunscreens, or apply low-e films to windows to block most solar rays which cause heat gain
  • Close south and west-facing curtains during the day on windows which get direct sunlight, and invest in reflective solar curtains
  • Upgrade the insulation in the attic
  • Service the air conditioning unit annually, and place it in the shade with proper air flow to ensure it runs efficiently
  • Install a house fan to cool the entire home at once as well as cool the attic above

Eliminate Internal Heat Sources

  • Lessen stove and oven use during hot days and enjoy a backyard barbeque or cookout, keeping the heat out of the kitchen and in the great outdoors.  When cooking inside do so in the evening and employ use of the microwave, toaster-oven or counter-top grill which produces far less heat than the stove or oven.
  • Switch to newer, compact fluorescent lights which use less energy and produce far less heat than incandescent lights
  • Pass on the hot-drying cycle of the dishwasher and let dishes air dry, or dry them by hand
  • Line-dry clothes rather than using the dryer, or use the lowest heat setting on the dryer
  • Take shorter showers that are cooler, and turn on exhaust fans and open windows to properly ventilate the area, allowing excess heat to escape
  • Turn computers and other electronics off when not in use, and use electronic devices such as TV’s less often throughout the day

Combining the various home fixes while eliminating internal heat sources can turn out to be the best ways to keep your home cool and save energy during hot summer months.  Just try some and see how that energy bill decreases!

Waldwick AC Tip: Outdoor Air Conditioning Components

April 23rd, 2012

As long as all the parts are working well, your Waldwick air conditioning system is a modern convenience you can easily take for granted and overlook. Cool air makes our lives simply better, but is a complicated process based on an old theory and modern technology.

No matter the size, in every unit, the basic purpose is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place. This process easily divides into indoor and outdoor components.

Air Conditioning 101

Utilizing the basic principal of thermal energy that heat gravitates toward cooler temperatures, compounds known as refrigerants travel through a closed looped system, repeatedly transforming between liquid and gas forms. Chosen for their ability to rapidly change at low temperatures, they alternately absorb and release heat along the way.

Having expanded to a vacuous state with plenty of room between molecules to absorb heat, the refrigerant is compressed tightly, condenses back into liquid form and releases the heat to the outdoors.

In the Box Outside

Placed on a small slab on the ground alongside many homes or on the roof of large buildings, air conditioning units contain the compressor and condensing coils that enable the main (and noisiest) function of the process.

The refrigerant is contained within a closed loop, entering the compressor as an expanded gas full of heat.  Under pressure, that heat is released when the molecules are squeezed so tightly together the refrigerant returns to its liquid state.

The Passing into the condensing coils, a series of delicate fins, the released heat is allowed to dissipate through the fins into the air where a small fan blows it away.  Water is also a by-product of the condensation and drains into a pan and eventually into the ground.

The condensing coil ends at the exchange valve where it is held to create just the right pressure for the evaporating coil indoors to operate at its maximum efficiency.

Refreshing Maintenance

When maintained on a regular basis, your Waldwick air conditioning system requires little attention and over sight beyond scheduled appointments with a company like DB Heating & Cooling, Inc.

Paramus Air Conditioning Installation Tip: Air Conditioners and Humidity

April 9th, 2012

Ever wonder why all of those Paramus air conditioners hanging out of people’s windows are constantly dripping water? All they’re actually doing is disposing of the moisture they’ve removed from the indoor air. That’s right – air conditioners are dehumidifiers too.

When you think about it, it makes a lot of sense. After all, you know how much more uncomfortable 90° is when the humidity’s up around 90% than when it’s closer to 60%. Of course, some air conditioners are better at removing moisture from the air than others, so you should definitely consider how well an air conditioner dehumidifies when evaluating your air conditioning options.

Why Humidity Matters

High humidity, even at lower temperatures is uncomfortable. But there are more reasons than simple comfort to want an air conditioner that reduces indoor humidity levels. For instance, high levels of humidity promote the growth and spread of several allergens like dust mites and mold spores. High indoor humidity can also cause problems for the wood fixtures and furnishings in your home.

The Importance of Proper Sizing

Most air conditioners do a decent job of controlling humidity indoors. But depending on the severity of your problem and the typical levels of humidity in your area during the summer months, you may want to pay special attention to each unit’s capabilities when evaluating your options.

An air conditioner’s ability to maintain proper humidity levels indoors has a lot to do with how well it’s matched to the size of your room as well. An air conditioner that’s too small likely won’t get the humidity or the temperature down to a comfortable level. On the other hand, that doesn’t necessarily mean that bigger is better.

In fact, an air conditioner that’s too large for the space you’re using it to cool will have a hard time bringing down the humidity level. Sure, you’ll wind up with a cold room, but that room will remain damp, making it no more comfortable than it was before the air conditioner was turned on.

For all of these reasons, it’s important to carefully evaluate your options when buying a Paramus air conditioner and make sure that the unit you buy is the right kind and size for the area you’re cooling. A little extra time spent researching your options will make your home infinitely more comfortable this season. If you have any questions about which air conditioning system is right for your home, give DB Heating & Cooling a call!

Is Your Hackensack Heat Pump Malfunctioning?

March 26th, 2012

In a perfect world, you would never have to worry about things like malfunctions or repairs. Everything would just work without ever needing to be maintained or fixed, and you could spend your time and energy on more enjoyable pursuits.

Unfortunately, no such perfect world exists. Things wear out and break down, often at the least opportune time. And of course, your Hackensack heat pump is not immune. Despite being a great all around machine, a heat pump can malfunction, just like anything else.

But how can you know whether your heat pump is not working right? Here are some signs and symptoms that are often indicative of common Hackensack heat pump problems:

  1. Too Much Noise – Whether emanating from your car or your usually quiet heat pump, noises are often the first sign that something is amiss. You should expect your heat pump to make some noise; the compressor and air handler are two culprits. However, if it starts making more noise than it did before, something may be up. Sometimes this is as simple as some loose fittings, but it’s still something that should be checked out.
  2. The House Is Too Cold – Obviously, if you get a heat pump to heat your house, you expect it to do just that. So, if your home is too chilly, you know something is amiss. If it’s way too cold, the heat pump may not be running at all, which can be the result of a serious malfunction. If it is only a few degrees below where you set it, it may be a different problem. It could be that something is malfunctioning in the heat pump, but it could also be that the outside air is too cold for the heat pump to keep the house warm. In that case, the best solution is supplemental heating.
  3. The Heat Pump Turns Off Too Soon – If your heat pump seems to be shutting off too quickly, it may be short cycling. That means that it is turning off before getting through its entire heating or cooling cycle. Frequently this is simply caused by dirt or debris around the outdoor coil, in the air handler or in the filter. Check these areas out and clean them. In general, you will want to keep the various components of your heat pump clean in order to ensure the best performance.

These are just some of the main symptoms of common problems. Other things can go wrong with your heat pump, although it is not very likely. As a general rule, if you notice your heat pump performing strangely or doing something it hasn’t done before, it’s best to get it checked out by a New Jersey heating and air conditioning contractor.

Waldwick Indoor Air Quality Tips: Improving Indoor Air Quality with UV Germicidal Lights?

March 14th, 2012

Ultraviolet germicidal lights improve indoor air quality in your Waldwick home by killing the harmful bacteria, viruses, and toxic mold that can cause respiratory problems and other health concerns. These microorganisms spread by releasing airborne spores containing the genetic material used to create a new organism. UV lights use a wavelength of ultraviolet light to destroy the organism’s DNA, which takes away their reproductive capabilities and also kills them.

UV germicidal lights are fairly inexpensive and can be installed to work with your existing forced air HVAC system. They are typically used in tandem with either an electronic or mechanical air cleaner. While air cleaners can filter pollen and other irritants, UV germicidal lights destroy the viruses and mold spores once these pollutants have been trapped by the air cleaner. After the air has been filtered through your HVAC, it will circulate more easily through system and increase the efficiency of the unit. In addition, UV lights are useful in killing hidden mold growth, which can only be detected by special thermal imaging equipment.

Homeowners with particularly chronic allergy problems or extremely poor indoor air quality choose to install both types of air cleaners, in addition to a UV light, for the ultimate protection from indoor air pollutants—from bacteria to pet dander.  If your home lacks adequate ventilation, or if you are unable to control the source of common pollutants, you might benefit greatly by installing UV germicidal lights. Poor indoor air circulation can exacerbate the spread of harmful microorganisms, so make sure you have proper ventilation if you don’t have UV lights in your home.

UV germicidal lights have also been used to filter tap water because they are more reliable and easier to install than other water treatment systems. However, they are typically used to provide cleaner indoor air.

Call the indoor air quality experts at DB Heating & Cooling if you have questions or concerns about the quality of the air inside your Waldwick home.

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

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!

Waldwick Heating Repair Question: Why Is My Air Handler Squealing?

February 22nd, 2012

Unusual noises coming from your Waldwick home’s HVAC system never a good thing; they make you worry that something is wrong.

It’s true that an unusual noise does often mean that something needs to be fixed; however, a noise emanating from your HVAC system does not necessarily mean a major repair. You should always have a technician check out if you suspect a problem with your system, but not all problems are going to be expensive to fix.

One common noise that homeowners notice and complain about is a squealing noise originating in the air handler. Usually, this noise is coming from the fan belt that connects the blower fan and the motor. Over time, the belt can stretch out and become worn or misaligned, which makes it slip and generate that aggravating squealing noise.

So, while the squealing can be annoying and unpleasant, a slipping belt is by no means major. A belt is an inexpensive part and a technician can install it in just a matter of minutes.

As long as the noise is a squealing and not a grinding, this simple fix wil often take care of the problem. If you hear a grinding noise, however, immediately shut the unit down and call a technician. This may mean that your motor bearings are worn out and need to be replaced ASAP before further damage is inflicted on the motor itself. If you suspect a problem with your air handler, give DB Heating & Cooling, Inc a call today!

Hackensack HVAC Guide: Seasonal Air Quality Control

February 8th, 2012

For people who suffer from seasonal allergies in Hackensack, air quality is a key concern. Allergens in the air cause brutal bouts of sneezing, runny nose, itchy eyes and even sinus headaches. Even taking refuge indoors will often not assuage these symptoms, as indoor air is often comparable to outdoor air in terms of allergens and overall quality.

That is, unless you take care to control the seasonal air quality in your home, which can not only help ease the suffering of allergies, but also soothe asthmatics, keep out pollutants and generally promote better overall health.

How do you go about controlling the air quality in your home? To start, try these simple tips:

  1. Vacuum carpets regularly. Use a vacuum with a HEPA filter and invest in some allergen suppressing bags.
  2. Keep your vents clean. This is also a good maintenance practice to lengthen the life of your ventilation equipment.
  3. Dust hard surfaces and wash bed linens weekly.
  4. Install HEPA filters in your ventilation system, such as in air conditioners or other air handler units. Use a higher rated filter to keep out more allergens and pollutants.
  5. Invest in and use an air purifier. Again, make sure to get one with a HEPA filter.
  6. Have your home tested for radon and carbon monoxide. Have smoke, carbon monoxide and radon detectors working properly at all times.
  7. Use a humidifier to keep overly dry air from irritating sinus passages.
  8. Keep doors and windows closed tight, especially during allergy season(s).

By taking charge of the air quality in your Hackensack home, you also take control of a measure of your family’s health. Some of these measures require at least a bit of an investment – for example, higher rated HEPA air filters are often more expensive and need to be changed more frequently – but the benefits to your well being and that of your family are clearly well worth it.
