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

Friday, June 29th, 2012

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!

What Professional AC Maintenance Includes

Tuesday, May 29th, 2012

Besides the cool air, what we like most about having air conditioning in Abington is that we don’t have to do anything to still live in a cool climate when it’s boiling outside.  With programmed thermostats adjusting the temperatures automatically, we don’t even have to turn it on.

Therefore, it is very inconvenient (not to mention uncomfortable) when our unit misbehaves and forces us to pay attention.  Our first inclination, suddenly over-heated,  may be to call for help, but often the expensive repair can be accomplished easily or avoided completely by checking the drain line that may be clogged.

When it gets more complicated, it is important to consult an Abington air conditioning professional.

Air Conditioning 101

Air conditioning is a process which involves the rapid evaporation and condensation of chemicals called refrigerants, compounds that have properties allowing them to change from liquid to gas and back again at low temperatures.

Simply stated: when the liquid evaporates and transforms into gas it absorbs heat.  Compressed tightly together again, the matter condenses back into liquid with a residue of unwanted moist heat that must be released to the outdoors.  Over the course of handling the air to cool it, air conditioners are able to filter dust and dehumidify the air as well.

Annual Service

Air conditioning units are designed to last for a decade or two of virtually trouble-free comfort, so long as they are maintained regularly.  A service contract with a reputable company ensures reliable maintenance and establishes a relationship so that if anything should go wrong, your call for help will be at the top of the list with a mechanic who likely knows the details of your particular unit.

You annual maintenance visit will include all of the following minimal tasks:

  • a check for the correct amount of refrigerant in the system;
  • a pressurized system test for any leaks using an actual leak detector tool;
  • a controlled evacuation and disposal of any excess refrigerant instead of an illegal toss in the dumpster;
  • a check for and seal of any duct leakage within the in central systems;
  • a measure of air flow through the evaporator coil;
  • a verification of the correct electric control sequence, making sure the heating and cooling systems cannot operate simultaneously;
  • an inspection, cleaning and maintenance of the electric terminals and applying a non-conductive coating if necessary;
  • a check of all belts for tightness and wear;
  • a check for oil in the motors;
  • a check for the accuracy of the thermostat.

How to Check if Your HVAC System Is the Right Size

Friday, February 17th, 2012

Do you ever feel that your Chalfont home just doesn’t get cool enough during the warm months or warm enough during the cold months? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard and the furnace in your basement should be making your home as comfortable as possible. But in many cases, they are not.  That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your Chalfont home to when each zone is occupied.

Steps to Take When Your HVAC System Breaks Down in Jamison

Friday, September 9th, 2011

Imagine this – it’s a sweltering summer day in Jamison. The humidity outside is obscene, hitting you like a wall when you open the door. So, the only place you want to be is on the couch with the cool air conditioned air being blown across your face. Sounds pretty good doesn’t it? Now, imagine what happens when that cool conditioned air stops flowing.

A breakdown in your HVAC system is the absolute last thing you want to experience on a day where the mercury dings 90+ but it can happen, and the only way to ensure things don’t get out of hand is to take the following steps.

  1. Check Common Problems –While the system itself could be broken, make sure there are no other issues involved. Frequently, the electricity supply can be interrupted by a power surge or a tripped breaker. In both cases, you can usually get the system back online by yourself. However, you should call an electrician to inspect it as soon as possible.
  2. Does it Turn On – If the air conditioning system turns on and simply doesn’t provide enough cooling for your home, it is likely a problem in the unit. In this case, check other common problems. Clogged filters can severely reduce efficiency and if the system freezes over, it may stop providing enough cooling.
  3. Still Not Working? – If the system refuses to turn on and there are not clear problems that you can fix yourself, it’s time to call a professional. A professional HVAC contractor should be available almost any day of the week for emergency calls like this. Of course, in the middle of a heat wave or cold snap, it’s very likely that they may be booked up for a couple days. To avoid this happening, have routine maintenance done as often as recommended to avoid the possibility of being without cooling or heating indefinitely.

A good HVAC system is the only thing standing between you and discomfort, or worse, danger to your health. Don’t let the system go into such disrepair that you can’t use it at all.

Save Money in the Long Haul with AC Maintenance

Friday, September 2nd, 2011

Every year, it’s recommended that you have an HVAC contractor visit your Blue Bell home and tune up your air conditioner. This visit will ensure the system is ready for the intense, regular use it will receive during the hottest months of the year. How much money can this visit save you, though? Let’s take a closer look.

Cost of Operating Your Air Conditioning

An air conditioning system on average costs a homeowner between $500 and $1500 per year to operate depending on the length of the cooling season and the efficiency of that air conditioner. That number represents top efficiency for the unit, however. When a system has dirty filters, hasn’t been cleaned properly or the thermostat is no longer calibrated accurately, the cost increases – sometimes dramatically.

Just how much more could you be spending on cooling each month when this happens? The EPA’s Energy Star website estimates an increase in cost of between 10-30% resulting from poorly maintained systems, and it can be even higher if your system is old and is severely affected by a drop in energy efficiency.

Annual Tune Up Necessities

So, what should be at the top of your tune up list? If you call a contractor, they will perform a variety of tasks including:

  • Inspect Coolant and Pressure Systems
  • Calibrate the Thermostat
  • Tighten Wiring, Capacitors, Relays and Contacts
  • Clean the Evaporator Coil
  • Clear and Clean the Condenser and Condensate Drain
  • Inspect the Condenser Fan and Motor
  • Check Compressor Efficiency

This is just a starter list for standard tune up of a central air conditioning unit. You can supplement this tune up by checking your filters once every 30 days and clearing away debris from around any outdoor units. You should also check your thermostat monthly to ensure it is working properly. If not, call for an inspection to avoid heavy increases in operating costs.

Major repairs to your air conditioning system generally take less than a day and when you’re on an annual maintenance plan, they cost significantly less than if you needed someone to fix the device in an emergency situation.
