Air Conditioning in Bergen County: Why Your Thermostat Matters

Monday, April 8th, 2013

While spring has only just begun, many homeowners are already thinking of the approaching heat this summer. Spring is the time of cleaning, organizing, and ensuring that your air conditioning system is ready to perform on even the hottest days of the summer. While we think about the compressor motor, the various coils, refrigerant, and ductwork, the thermostat is just as important as other aspects of the AC system. Without it, your AC cannot properly adjust to your desired temperature. For more information about the role your thermostat plays in cooling your home, call DB Heating & Cooling for air conditioning in Bergen County, NJ today.

The conventional non-digital thermostat uses a mercury switch to assess the temperature. Because mercury is a liquid metal, it conducts electricity and flows in a way not dissimilar to water. Inside this switch shaped like a vial are three different wires. The circular rotation of thermostat displaces the balance of the mercury switch, itself connected to a bimetallic strip that expands and contracts according to the temperature, which communicates to the heater or AC to turn on. Digital thermostats use something called a thermistor to sense the temperature and a microcontroller to convert that information into a LCD display. Programmable and wifi-enabled thermostats allow for greater customization.

Your thermostat controls your entire heating and cooling system. That’s a lot of responsibility for such a compact device. If there is something wrong with it, it can throw off the performance and efficiency of the heating and cooling systems. It’s imperative that your thermostat is properly calibrated so that it can accurately sense the temperature in the home and send that information to the heater or AC. Installing a programmable thermostat can dramatically increase the energy-efficiency of your home, without sacrificing any comfort.

Thermostats can have a significant impact on your cooling system. Make sure you’re ready for the summer heat with a programmable thermostat. For air conditioning service in Bergen County, NJ, call the experts at DB Heating & Cooling today!

Benefits of a Ductless Mini Split System in Oradell

Monday, November 12th, 2012

With all of the home heating and air conditioning systems on the market today it can be difficult to determine which heating and cooling option is best for your Oradell home. Discussing your heating and air conditioning options with a local professional service provider is the most fail-proof way to ensure that you are investing in the best heating and cooling system for your home and personal heating and cooling habits. If you are not familiar with ductless mini splits and the potential benefits that they hold for your home and comfort take a few minutes to review this helpful information from the home comfort professionals at DB Heating & Cooling. You may decide that a ductless mini split system is the best choice for your home, and DB Heating & Cooling can help you verify that decision.

First of all, the most obvious benefit of a ductless mini split system is right in the name. This heating and air conditioning option completely eliminates the need for ductwork in your home. While a properly installed, well-maintained duct system can efficiently and effectively circulate conditioned air throughout your home, ductwork is often one of the biggest reasons for inefficient energy use. By removing ductwork from the equation, ductless mini splits also remove this risk. A simple conduit containing refrigerant and power lines is all that is needed to connect the outdoor condenser unit to the indoor, wall-mounted air handlers that this type of heating and air conditioning system uses. These air handlers, up to four per outdoor unit, heat and cool the rooms of your home individually and directly.

The use of these multiple air handlers also makes it easy to create temperature control zones in your home and to maintain individual temperatures within each zone. This is a great way to boost energy efficiency in your home, helping to reduce energy costs. You no longer have to heat empty bedrooms because you want to keep the dining or living rooms comfortable. Likewise you choose to lower the temperature in the kitchen if you are doing a lot of cooking and begin to overheat while still keeping the rest of the house perfectly warm.

Whether you want to cut down on the amount of energy that you use in your home or simply avoid the cost of a duct system installation, ductless mini splits may be the solution that you’re looking for. If you think that a ductless mini split system installation is right for your Oradell home, call the heating and air conditioning professionals at DB Heating & Cooling. We’ll help you make the best decision for your comfort.

Waldwick AC Repair Guide: Icing Problems on Air Conditioner Cooling Coils

Monday, August 20th, 2012

Air conditioning cooling coil icing problems can arise for a couple of reasons: either the air filter has not been properly replaced, or there is a condensing coil leak.  It is best to check and test the easiest problem first and then move on from there.

It is important to replace your Waldwick air conditioner’s filters as often as is recommended by the manufacturer.  A common result of not replacing filters frequently enough is a buildup of dust and dirt on the filter, which causes reduced air flow throughout the air conditioning unit.  With reduced air flow, the evaporator coil or cooling coil within the air handler can become blocked by ice or frost build-up.  Having cooling coil icing can significantly reduce or completely stop the amount of cool air being produced by an air conditioning unit.

Easy steps to diagnose and resolve air conditioning cooling coil icing problems:

  • Visually inspect the air conditioning cooling coils to check whether reduced air flow has been caused by cooling coil icing.  If ice or frost is found on the coils, thus blocking air-flow, proceed with the next step.
  • Turn off the air conditioning system completely to allow ice to evaporate, the unit will have to remain off until all ice is completely melted and drained away from the unit
  • Replace all dirty filters on the air conditioning unit
  • Once the a/c unit is de-iced and has fresh filters, it is safe to turn the system back on, to test whether the icy build-up happens again

If after completing these steps, when the air conditioning unit is turned back on cooling coil icing happens again, this could mean one of two things.  Either too little of the refrigerant is being released into the cooling coil due to a clogged capillary tube or a stuck thermostatic expansion valve.  Or the refrigerant charge is too low due to a refrigerant leak.  A refrigerant leak can happen at any point in the refrigerant piping system which would then need to be soldered and resealed, or it can happen in the cooling coil or condensing coil which could mean the entire coil needs to be replaced.  Fixing of refrigerant leaks should be handled by a Waldwick air conditioning professional.  Contact an experienced HVAC technician at DB Heating & Cooling that can identify the air conditioner cooling coil icing problem and execute the proper solution.

Programmable Thermostats and Your Paramus AC

Monday, August 13th, 2012

Air conditioning makes our Paramus homes comfortable during a hot summer day. However, air conditioners need electricity to run, and most of us are trying to reduce our home’s energy consumption. There are a number of ways you can make your air conditioning system more efficient, including upgrading to an ENERGY STAR rated unit and scheduling regular maintenance, but one of the easiest steps to implement is installing a programmable thermostat.

Programmable thermostats automatically adjust the temperature in your home depending on the time of day. You can save up to 10 percent a year by turning down your thermostat back ten degrees for eight hours a day! Most models allow you to store multiple daily settings, so you can turn you air conditioner down during the day when you are at work and while you are sleeping, and still have the temperature cooler when you need it. You can also still manually adjust the temperature without affecting the normal settings, giving you complete control and helping you save energy.

Programmable thermostats are not all made the same, and there are many different makes and models. An Paramus HVAC contractor will go over the different features available to you so you can decide which best fits your needs. Different thermostats work better with different systems, for instance some heat pumps need thermostats that have multi-stage functions, so it is best to consult with a professional before deciding what to purchase.

Programmable thermostats allow you to save energy without sacrificing comfort, which is something that all of us are looking for. If you are looking for a simple, affordable way to improve your Paramus HVAC system, a programmable thermostat is a great choice. Most are easy to read and easy to use, call DB Heating & Cooling Inc today to learn more about having a programmable thermostat installed in your home!

Teaneck AC Tip: Cooling Coil or Evaporator Coil Diagnosis & Repair for Air Conditioners

Monday, July 16th, 2012

Inside the air handler of your Teaneck air conditioning system is a cooling coil or evaporator coil. From a home cooling perspective, this is where the magic happens: where the actual cooling occurs. So, if there is a problem with the cooling or evaporator coil, you will notice a decrease in the performance of your AC system.

You may notice that the air flow has slowed significantly or even stopped, even though you can hear the air handler running. You may also notice that the air isn’t as cool as it used to be or should be. Aside from having a house that is not cool enough, this can also cause problems like high electricity bills or damage to other parts of the air conditioner. You technician will do the following to check your coil. Remember, all AC repairs are best performed by a licensed professional.

 Diagnosis

First, your tech will look at the cooling coil. Some problems are obvious enough upon visual inspection that no further diagnostics or major repair is necessary. To inspect the cooling coil on your air conditioner, they will first turn off the electricity at your fuse panel or breaker box. Then the  access panel on the air handler that can be removed to at least partially expose the coil.

They will look for things like:

  • Dirt and debris
  • Mold
  • Staining that indicates a refrigerant leak
  • Ice or frost
  • Damaged fins on the coil

 Repair

Any of these could be the culprit that is degrading the performance of your AC system. For most repairs you will want to call in a licensed technician. Especially if the problem is something potentially hazardous like mold growth or a refrigerant leak, you don’t want to take the risk. Let a Teaneck air conditioning professional like DB Heating & Cooling who is trained in safely and effectively repairing the problem take care of it, so that your home can be comfortable again.

Waldwick Air Conditioning Tip: What is the COP and Why Is It Important?

Monday, July 2nd, 2012

If you’ve been researching air conditioners in Waldwick, you’ve probably seen all sorts of numbers associated with each model. One of these numbers is the Coefficient of Performance (COP). While it’s good to gather as much data as you can before you make a purchasing decision, you also need to know what that data means if it’s going to help you make the best selection possible.

Measuring COP

Calculating the COP for any air conditioning model is relatively simple. The number you see displayed on the box is the ratio of energy input to cooling output. For the most part, the air conditioners you’re probably been looking at have a COP of between 2.5 and 4.0, although newer models are beginning to appear with COPs of up to 5.0.

The higher the COP, of course, the more efficient the air conditioner, so it makes sense to take this number into account when you’re making your purchase. You should also keep in mind, though, that the COP is not a constant measurement. The warmer it is outside, the lower your unit’s COP will be. However, this is standard across all units, so a relative COP comparison is still a viable evaluation method.

If you’re not sure what COP you should look for or whether a lower number will be effective for your home (especially if you only need to cool a small space), you should talk to a Waldwick air conditioning professional who can help you match the right COP level to your particular living space.

Improving Efficiency

While it’s always a good idea to get an air conditioner with the best energy efficiency ratings possible, that’s not the only thing you can do to reduce your energy usage and keep your cooling costs down. For instance, there are plenty of ways to keep your home naturally cooler without even turning on the air conditioner.

Even when you do need to flip it on, anything else you can do to reduce the indoor temperature will make it easier for your Waldwick air conditioner to keep your house comfortable. So put up some awnings, run the ceiling fan and close the blinds to block out that harsh afternoon sun. The more you can do to reduce your indoor temperature naturally, the less your air conditioner will have to do, and the lower your cooling costs will be. For more information about how to improve your air conditioning system’s efficiency, give DB Heating & Cooling, Inc. a call!

Waldwick HVAC Question: Do Heat Pumps Work for Air Conditioning?

Monday, June 4th, 2012

It’s possible that in the course of your search for a new air conditioning system, you read or were told about heat pumps. Doesn’t sound right, does it – heat pumps providing cooling for your home? Regardless of the seeming misnomer, heat pumps are actually much older and more reliable cooling technology than you know. And once you understand how these units work, the name makes much more sense.

What Is a Heat Pump?

Technically every refrigerant containing air conditioner is some form of heat pump. A heat pump is a device that removes heat from one area and transfers it to another. So, in the case of your Waldwick air conditioner, warm air cycles into the condenser, the heat is removed, and the cooled air is circulated back through your home. The actual science behind this is slightly more complicated, but the gist is simple – cold air isn’t produced and then pumped into your home; warm air is removed.

Your refrigerator and freezer operate under the same principle. It works so well that it’s been a standard technology for nearly 100 years, albeit with quite a few upgrades and enhancements. So, if an air conditioner already is a heat pump, why are these devices called something different? Because heat pumps can do so much more.

Heat Producing Heat Pumps

A true heat pump can work in two directions. It can extract heat from your home or it can extract heat from outside and pump it into your home. A true heat pump offers year round climate control because it both heats and cools – not too shabby if you think about the cost of a furnace and central AC system.

So, back to the main question – should you purchase a heat pump for your air conditioning needs? The short answer is “it depends”. For the most part, a heat pump is comparable to the same air conditioning model in terms of energy efficiency and capacity. The major difference is its ability to heat your home. So, if you are interested in ditching the furnace or boiler, it may be a great upgrade. If not, a standard air conditioner can get the job done equally well. If you are interesting in learning more about how a heat pump would work in your Waldwick home, give DB Heating & Cooling a call today!

Teaneck AC Contractor Tip: Green Your HVAC

Monday, May 21st, 2012

Regular Maintenance Avoids High Costs

No matter the energy rating of the appliance, a schedule of simple maintenance and replacement of filters can make a significant difference in its longevity.  A furnace rated at 95% efficient will burn nowhere near that great a rating if the air is blocked and unable to pass through the filter without effort.

Fan belts on the blower motor can loosen over time and become ineffective, forcing the heater to burn longer and hotter to distribute air that should normally breeze through the ductwork.  Working so hard, parts break and the furnace might need replacement.

New Thermostats

If left to our own habits, our Teaneck air conditioners and furnaces might run for hours under unnecessary circumstances because we are not thinking to turn our thermostats up or down.  At the change of seasons, in particular, it may feel warm enough to open a window while the heat is still adjusted to come on at those fresher temperatures that now seem so inviting.

In older homes, the replacement of the old dial thermostats with the newer digital versions can save on energy costs.  Smart phones allow adjustments to thermostats from anywhere in the world for the instance that a cold snap may threaten frozen pipes while we are away on vacation.

Changing World

Tax incentives, climate change and the economics of energy dictate that we look closely at our habits and find ways to conserve our resources. For more information about how HVAC improvements can reduce your energy bills, give DB Heating & Cooling a call today!

Teaneck AC Tip: Keep Your Home Cool and Save Energy

Monday, 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!
