Benefits of Forced Air Systems

Monday, August 13th, 2012

Forced air systems are usually hooked up to both a heating element and an air conditioning element, both of which send their pre-treated air through a series of ventilation ducts located throughout a building.  Many times the heating and air conditioning devices are separate, such as a gas furnace for heating and a central air conditioning unit for cooling.  Other times they can be one and the same unit like with packaged air conditioners and heat pumps which does both jobs with one machine.  This makes for a great deal of variety in the choices of heating and air conditioning types that are available for use.

With use of a programmable or digital thermostat there is a high degree of control with a forced air system.  You can Set time-of-day and day-of-week settings to accommodate when the building is in use and when it is not.  There are also options for setting temperatures in certain sections of your home while other sections remain untouched.  All of this allows for lower utility bills, since only the rooms which are used frequently are heated or air conditioned.

Air conditioners and heaters utilized today have much higher energy efficiency ratings than those of years past; couple this with a well maintained, properly sealed, insulated and balanced duct system and the energy-savings increase even further.

Forced air systems cost anywhere from 40% to 60% less to install than comparable radiant systems.  They also offer special features such as filtration systems and ultra-violet germicidal lights, which can keep your indoor air clean and healthy.

Carney Plumbing, Heating & Cooling is an air conditioning and heating company in Horsham that provides quality HVAC services to each client.  Let us assist you in determining which forced air system is right for your unique needs.

Problems Caused by Low Refrigerant in an Air Conditioning System

Monday, August 6th, 2012

Having the proper refrigerant level of an air conditioning system is one of the key components to having properly cooled indoor air.   The AC specialists at Carney Plumbing, Heating & Cooling can easily diagnosis the AC problems which could be a result of low refrigerant levels get your system back up and running in no time.

Low Refrigerant Levels Mean AC Problems

One of the most common signs of low refrigerant levels is having an air conditioner that only blows warm air or one that does not sufficiently cool an entire indoor space, leaving some rooms which are warmer than others.  This is because refrigerant is what creates the cold air, and without enough of it, you can never have enough cold air.

Frost build-up or icing around the condenser coils in the outdoor unit can mean a refrigerant leak has caused low refrigerant levels.  Because ice build-up restricts air-flow, this can mean less cool air flowing into various rooms.  Low levels of refrigerant can cause coils to drop in temperature which then creates frost or ice on the coils.

An AC system that will not turn on could also be a result of low refrigerant levels.  Newer HVAC systems have built-in safety controls which detect certain changes in how internal systems function and as a safety precaution, shuts down the air conditioner in certain circumstances rather than continuing to run and further damaging other internal mechanical or electrical systems.

These are some of the main AC problems caused by low refrigerant levels.  It is important to have a professional Harleysville  air conditioning company such as Carney Plumbing, Heating & Cooling assist you with your air conditioning concerns.  Our AC technicians provide air conditioning services such as air conditioner maintenance and repair, including fixing refrigerant levels and charging refrigerant.

Central Air Conditioning FAQ’s

Monday, July 23rd, 2012

Central air conditioning is a great convenience, but it can also generate a number of questions. If you’re experiencing any trouble with a central cooling system or are wondering what to look for in a system, keep reading. We’ve gather some information to keep you informed and confident about the purchase and use of your Perkasie central air system. If you’re beginning your research, it’s smart to start with questions to ask before scheduling an HVAC installation to ensure your investment aligns with your home’s needs.

What is a Central Air Conditioner?

This is a basic one, but many people are unclear on what exactly makes up a central A/C. There is a central unit containing the compressor which cools the air. This air is then forced through a ductwork system that distributes the cooled air throughout the structure. Blowers push the air through, and they pass through grated vents located in the walls or ceilings of a building.

How Do I Decide What Central System is Right for Me?

The best way to ensure that you are buying a properly sized central air conditioner for your home is to have an HVAC technician come and evaluate your living space. It is just as inconvenient to wind up with an oversized unit as with an undersized one, as this will result in clammy air that was cooled too quickly to be properly dehumidified. Cooled air will be over produced and wasted, lowering efficiency. An HVAC technician’s help will take the guess work out of choosing your system.

Why Won’t My Central Air Conditioner Cool?

There are a number of problems you could be experiencing if your central air conditioner is no longer cooling or is not performing at the level it once did. Checking your air filters is a good place to start. If they are dirty they will not let cooled air pass through efficiently and will need to be replaced or cleaned. Your refrigerant level may also need to be adjusted, or your fan could be running while your compressor is inactive. Another possibility are leaky ducts. Again, the best way to ensure that everything is working properly with your central system is to have a qualified HVAC technician perform an inspection. You can also review why it’s important to keep your AC condenser coils clean as buildup in this area can directly affect cooling performance.

When you invest in a central air conditioning system you should plan on protecting that investment. Failure to do so will result in subpar performance and damage to the system. The best way to keep your Perkasie central air conditioner working like new is with regular maintenance. Call the professionals at Carney Plumbing, Heating & Cooling with any concerns you have with your home cooling system. Regular care helps save money in the long haul by maximizing energy efficiency and preventing premature breakdowns.

Air Conditioning Tip: Indoor Air Conditioning Components

Monday, July 16th, 2012

Air conditioning in Lansdale is a modern convenience that we can easily take for granted as long as all the parts are working well.  In every unit, no matter the size, the basic process 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

Based on the principal of thermal energy which states that heat gravitates toward cooler temperatures, compounds known as refrigerants are moved through a closed loop system, repeatedly contracting and expanding between liquid and gas forms, alternately releasing and absorbing heat along the way.  The particular chemicals are selected for their abilities to transform from one state to the other at low temperatures.

While the refrigerant evaporates into a gaseous state within the looped system, it absorbs heat, removing the stale air from the space being conditioned and evacuating it to the outdoors. The warm air is pulled through ducts to meet with the cooling loop.

Ductwork

The cooled air is distributed through ducts or tubing and released into individual spaces.  Additional ductwork is required to remove the stale air and pull it back to be reconditioned as it passes over the loop containing the refrigerant.  The air is moved in both directions by a blower, usually electric and sized to handle the amount of air no matter the building.

Ductwork is also sized to handle appropriate volumes of air. To maintain efficiency, large trunks distribute along central lines to smaller ones reaching farther out. The return air is usually taken from common areas.

The grates are found in the walls, floors and often as part of the dropped ceiling. When combined with a forced air heating system, the total energy use is much more efficient.

Looped Coils

The refrigerant is enclosed in a loop where it can expand and contract to make its transformation from gas to liquid and back again.  To change into a heat-absorbing gas, it travels through the evaporating coils, an intricate series of delicate fins that meets with the ductwork to regenerate the conditioned air.

An exchange valve allows just the right amount of liquid refrigerant into the evaporator coils.  If there is too much, the tube is flooded too tightly to allow expansion of the molecules and room to attract the heat.  If too little, the process is inefficient.

Cool Maintenance

When set up and maintained on a regular basis, the system functions with little attention and over sight. To schedule a maintenance appointment today, give Carney Plumbing, Heating and Cooling a call!

Why is My Central Air Conditioner Making Noise?

Monday, July 9th, 2012

A good air conditioner is a life saver in the midst of a hot and sticky summer, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your Newtown air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.

  • Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems.
  • Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
  • Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to have a tech clean the condensate line and check for any clogs or blockages in the system.
  • Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a Newtown AC professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
  • Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.

Most noises from your Newtown central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call Carney Plumbing, Heating & Cooling before the problem grows.

What’s it Like to Work With Carney Plumbing, Heating & Cooling?

Customer Review | Lansdale | Carney Plumbing, Heating & Air ConditioningA wonderful customer details their experience with Carney Plumbing, Heating & Cooling .

“I called to get estimates for a heat pump and an air conditioning unit. Joe Hill came to our home to assess our needs. Within a few days, he called to ask whether or not we would like to have a back-up heat option in the event of choosing a heat pump. He said this would require an upgraded circuit box. I told him I didn’t want the back-up heat, and he put together the proposals for both a heat pump and A/C soon after. I believe I received an email with both proposals within a week of Joe’s first coming to our home. Before I received the proposals, I called Joe with questions regarding duct work as well as financing. He answered all my questions completely and assured me that we would be much more comfortable in our home regardless of which option we selected. When we decided to use Carney to meet our climate control needs, Jose contacted us to begin the application process for financing our purchase. This process took a couple of days, and Jose answered further questions we had regarding financing. Another associate called us to schedule installation, and within about a week of letting Carney know we were interested in their services, a crew was here to begin installation of a Trane XR15 AC system. The crew removed our old heat pump and installed the new system over the course of 2 days. They had to make a slightly larger opening in our ceiling to get the new unit in our attic. But before they did this, they asked our permission. They explained that without doing this, they would have to use a smaller and less efficient unit. They covered the opening in the ceiling with a cut-to-fit piece of foam, and they cleaned up each day before they left. They explained the operation of the thermostat to my wife and left the written instructions with us. They also provided us with the paperwork for financing. We are now much more comfortable in our home during the hot summer weather. I would definitely recommend Carney to anyone with climate control needs. Thank you.”

HVAC Guide: Saving Energy This Summer

Monday, June 25th, 2012

Everyone wants to make their home more energy efficient, it not only saves you money but it also makes your home more environmentally friendly. Upgrading your Hatboro HVAC equipment is a great place to start, but it can be hard to decide what to do first.

Before you start making changes, ask yourself the following questions:

How much do you spend on energy?

Paying attention to your energy bill from month to month is very important. A sudden spike could indicate a problem with your Hatboro HVAC system or other appliances in your home. If you start trying to embrace an energy efficient lifestyle, your energy bill can help you keep track of how well you are doing.

Are there benefits to this upgrade?

In addition to being energy efficient, you should discover if there are any other ways that a change can benefit your home. For instance, a new air conditioner could make your home more comfortable, or zone control could make it easier to keep every room in your home the desired temperature. You’d be surprised how many energy efficient upgrades can really improve your whole home and not just your energy bill.

What is your budget?

Budgeting is never fun, but it’s important step to figuring out what you should change first. While it would be great to replace your air conditioner and furnace for ENERGY STAR rated models, it’s a big investment. You can try the little things first, like improving you insulation, repairing air ducts, and sealing air leaks. After you have saved up and improved other parts of your home you can work on replacing your HVAC equipment.

Improving the energy efficiency of your home will make it more comfortable and lower your utility bills. If you have any questions about energy efficient upgrades you can make to your home, call Carney Plumbing, Heating & Cooling today!

What Are Thermostatic Expansion Valves?

Monday, June 11th, 2012

The thermostatic expansion valve, sometimes known as a TEX, TEV or TXV, is a critical piece to influence the efficiency of your Blue Bell air conditioning and refrigeration units.  A tiny sensor controlling the evaporating phase of process, the valve can have a big effect.

Cool air is manufactured by a re rapid movement of a refrigerant between liquid and gaseous states.  Compound chemicals that are able to do this at a low temperature are compressed and expanded, absorbing and releasing heat at different points along the way.  The TEV controls the flow of the refrigerant into the evaporator coils according to the temperatures of the various ingredients.

Cool Air 101

To condition air, the refrigerant, most often freon or another fast acting, low temp compound, evaporates into a gas that runs through a coil and absorbs heat.  Passing through a compressor, the freon condenses under pressure back into a liquid again and releases the heat, becoming cool enough to chill a party.

Too much freon in the evaporator tube and the pressure is not low enough to expand to gas and absorb heat, working inefficiently for no gain.  Too little freon and the conversion is also ineffective by not reaching the density needed to condense.

There are four types of valves with different benefits for different types of cooling environments.  With its ability to adjust minutely to changing conditions, the thermal expansion valve creates the perfect mixture of pressure and freon for more complicated systems.

At the Starting Gate

An interactive device, the valve senses the evaporator pressure and temperature and adjusts the flow of the refrigerant so as to maintain a given “superheat”, the differ­ence between the refrigerant vapor temperature and its sat­uration temperature.  By controlling superheat, the TEV keeps nearly the entire evaporator surface active while not permit­ting liquid refrigerant to return to the compressor.

Some valves operate on an electrical impulse from sensors that can measure the temperatures.  Others are open all the time.  The thermostatic expansion valve actually utilizes the pressure between the two sections to open or close itself, regulating flow based on the very same pressure it is designed to moderate.

Like the buildings they comfort, Blue Bell central air conditioning systems are varied and diverse.  There are nearly as many thermostatic expansion valves as there are units to receive them. Call Carney Plumbing, Heating & Cooling today if you need any air conditioning service in the Blue Bell area!

Air Conditioning Q/A: Why Is My Air Conditioner Not Cooling?

Monday, June 4th, 2012

Your Lansdale air conditioner can run virtually trouble free with just a little maintenance annually.  If these little things like changing the air filter and cleaning the drain are not done regularly, the neglected units can really lose their cool.

The Basic Course

Through a process which involves the rapid evaporation and condensation of chemicals called refrigerants, air conditioners use compounds that have properties that allow them to change rapidly from gas to liquid and back again at low temperatures.

Heat is absorbed when the liquid evaporates and transforms into gas, making the space around it cooler.  Compressing it tightly together again, the heated gas condenses back into liquid with a residue of unwanted moisture that must be released and is vented usually to the outdoors.

The newly cooled air is distributed through the house by means of ductwork, pushed by fans driven by electric motors.  As the air moves along, it passes through a filter and can be further de-humidified.

Problems in the System

If the filter is clogged, movement of the cooled air is slowed to the point we might think the unit is broken.  If the condensate drain is plugged, the motor can get damaged and stop producing.  Regular maintenance performed by the home owner or as a service of Carney Plumbing, Heating & Cooling can avoid or eliminate these simple aggravations.

When the heat builds, however, and cool relief seems nowhere near the air ducts, it may be time to call a professional to dig deeper to find the reason and suggest solutions.

Back to Cool

If not serviced regularly, the amount of refrigerant in the coils may decrease over time or the coils themselves could get clogged and impede the evaporation/condensation process.  A leak in the coils could drain the system, rendering the unit useless and wholly unproductive.

There are belts on each of the two separate fan motors which may be worn or loose, causing the fans to blow less efficiently.  The motor may need to be oiled or have a broken part that doesn’t allow it to push the air at all.

Most of the time, these fixes are relatively minor and do not threaten the life of the air conditioning unit.  Schedule an annual inspection and service from a certified Lansdale HVAC company like Carney Plumbing, Heating & Cooling today!
