Why is My Air Conditioning Freezing Up?

Good Deals Heating and Cooking air conditioning repairFreezing up or icing up of air conditioners is a frequently encountered problem. Irrespective of the fact, whether the unit is a window AC or central AC, the reasons and the solutions are similar.  One cannot ignore freezing up in an air conditioner. It gives rise to two problems: inefficient cooling and potential damage if not corrected.  The key is to know when to call for air conditioning repair.

To understand why an air conditioner is freezing up a thermodynamics principal needs to be understood. The Joule-Thomson effect states, that when a gas expands, its pressure as well as temperature decreases. This result happens when all the other parameters are kept constant. Similarly, when a gas is compressed, the temperature increases. In other words, molecules of the air feel hot when they are moving rapidly and when they move slowly, the air feels cold.

On this basis, the evaporator coil in an AC expands the refrigerant. This expansion causes the coil to cool. The cold coil then mixes with the air at room temperature, and the coolant absorbs the heat. The now heated refrigerant is then thrown out of the house by compressing it, which heats it up and transfers it outside. The cycle gets repeated many times, and the room gets cold. When there is a problem, the air conditioner’s evaporator coil gets much colder than it should, thus freezing up the AC. This freezing up happens due to several reasons:

No Enough Airflow Across the Evaporator Coil: ACs are meant to bring down the temperature by drawing away the heat. If the AC is not blowing the internal air correctly over the coil, the exchange of heat does not take place. Over time, the coil temperature will drop, and the AC freezes up.

Low Refrigerant: When the amount of refrigerant (freon) in the system is low, it still expands to the same amount. As stated above when gas expands, the temperature drops. As the temperature of the coil drops below the freezing point, the moisture in the air freezes when it contacts the coil, thus icing it up.

Mechanical Problems: If an air conditioning repair is required then the pressure change in the system leads to freezing up. The problem may include an obstacle in the refrigerant, a non-working blower, or a blocked filter.

High Outside Temperatures: When the outside air temperature is extremely high, and the AC is continuously running, the system pressure inside the unit will drop and cause freezing up.

For an air conditioner freezing up on a consistent basis, call for air conditioning repair to get to the root of the problem. For assistance in the Philadelphia area, contact Good Deals Heating and Cooling at 215-947-1166.

Improve Energy Efficiency With The Right Thermostat

Good Deals Heating and Cooling energy efficiencySaving electricity and improving the energy efficiency is a lifelong battle that can be hard to conquer. Many gadgets on the market can meet your needs and reduce the burden on the electrical output. One such electronic device is a thermostat which regulates the heating and cooling in the home. If you have the right type of thermostat installed in your home, you can save enormously on your electric bill.
The different kinds of thermostat that are available are:

Programmable

A programmable thermostat is a very sophisticated unit that allows you to input a schedule with settings that best suits your everyday needs. These thermostats can help you save on the heating and cooling costs by adjusting the temperature throughout the day.

Why Use Programmable Thermostats?

When the heating or cooling in your home runs continuously, there is a lot of wasted energy used. Does the house need to be so warm when you are at work? Or in the middle of the night while you are sleeping? A programmable thermostat allows the temperature to adjust automatically during the day based on who is home. When no one is home, set the temperature at an energy-saving level then have the temperature return to your comfort level before you return home.

Mechanical Thermostats

These basic thermostats are pretty easy to install and operate by metal bars heating up and cooling down. Although these may be as accurate, they are cheaper than programmable thermostats. These thermostats are not as smartly operated as the programmable thermostats but are still widely used due to the simplicity of their operative functions. For these to be energy efficient, the homeowner must manually adjust them. However, it is still unwise to use these thermostats as every time your temperature rises by 1 degree you end up consuming 10% more energy!

Electronic Thermostats

Electric thermostats contain a sensor that controls the temperature and are programmable as well. You can control the thermostat from an app on your phone or check the temperature in your house at any time. These types of thermostats are often part of a whole-house control system which includes security, lights (indoor and outdoor), sprinklers, and thermostat.

With the right choice of the thermostat and a careful inspection of all the essential factors such as keeping track of your saving potential and making the correct and smart use of the thermostat options, you can save an enormous amount of energy and money too!

Steps to Take Before Turning on Your Air Conditioning

Good Deals Heating and Cooling air conditioner repairAir conditioners are mostly used during the summer months when the temperatures and humidity are high. During those hot months, most people use their air conditioners regularly. Spring is the time of year when the weather is in transition, so it means it’s time to make sure the air conditioner is working. Before turning on your air conditioner, here are a few steps to follow:

Look at the thermostat: the checking the thermostat is crucial, if it’s not working correctly, install a new, programmable thermostat to make the system more energy efficient.

Check the ductwork: Ductwork can become disconnected allowing air to escape making the whole system overwork.

Check air vents: the air vents around the home can be blocked. Toys, drapes, and furniture can block the air vents and affect the airflow.

Check the drain line: the drain line should be clear. Keep the drain clear and if clogged, clean it out.

Change air filter: At a minimum, the air filter should be changed before each heating and cooling season. Changing air filters should be on the TO DO list for every three months.

Check electrical circuit: before turning on the air conditioner, the circuit should be connected correctly.

Inspect the condenser unit: Any spring maintenance routine should include inspecting the outdoor condenser unit. It should be clear of other equipment and debris to enhance performance.

Insulate the refrigerant lines: the refrigerant lines need to be insulated to improve the system’s efficiency. Insulation repair is for professionals only.

Inspect the outdoor wiring: inspecting the electrical wire both outside and inside. Any wear or damage should be repaired and re-installed by a professional before using the air conditioner.

After making sure the indoor and outdoor equipment are working and connected securely, test the system.

  • Lower the thermostat temperature before turning the system on.
  • Listen and make sure the fan is running and the air coming out is cool. Let the system run until the indoor temperature cools off during summer.

If you don’t feel comfortable around electrical equipment then schedule an air conditioning maintenance appointment with an HVAC professional.

Is Your Air Conditioning Contributing to Ozone Depletion?

Good Deals Heating and Cooling air conditioning repairFor decades now, a variety of standard household appliances have used chemicals that are harmful to the environment. This practice has been a particular problem with air conditioners. The most common refrigerant, R-22, can do a lot of damage to the ozone if it leaks out into the atmosphere. For that reason, R-22 and other harmful refrigerants are being phased out. If your air conditioning unit uses these refrigerants, then it’s time to take action.

The ozone acts as a layer of sunscreen around the entire planet. Without it, the Earth would be exposed higher levels of ultraviolet rays from the sun, Instead of being absorbed by the ozone layer keeping the stratosphere cool, vastly increasing the effects of global warming. Without the ozone, we would be toast which is why governments all over the world are taking action against products which pose a threat to the ozone.

As of 2020, it will be illegal to manufacture any new air conditioning units using R-22 as a refrigerant. That means any units that rely on R-22 will have to be repaired using recycled parts. Repair costs for these older units will skyrocket, and only get higher as time goes on. A more cost-effective solution is to invest in a new unit now. Not only will you save yourself a small fortune in the long run, but you’ll also be doing your bit to help the environment.

There is a nameplate on all air-conditioning units, which state the type of refrigerant used. Check if yours uses R-22.  If so, start planning to make the switch to a new, more environmentally friendly unit. Many brands are already moving away from these harmful refrigerants, so even before the 2020 cutoff date. R-22 is already illegal in many countries. Make the switch today, and you can keep cool without heating up the planet- a win-win situation for everyone.

AC System Maintenance Basics

Spring HVAC Maintenance TipsKeeping your AC running is crucial especially with children in the home. A broken down AC will mean exposing your home to the extremities of weather. This can be done as a DIY. It is however recommended that you pick an expert that will fulfil the task professionally. Here are key steps when it comes to AC system maintenance and management

Shut the power down

The AC works on an electrical system that can be quite dangerous if operated while the power is on. You will need to completely shut the power down. It is wise that you do this right from the breaker box to reduce the risks if someone else switching the power back on.

Remove debris

One of the first steps is to open up the system so as to clear off all the debris in the condenser. The AC system comes with a lot of moving parts. These may get worn out and create unwanted debris. Dust may also collect in the AC blowing into the home. Use a screwdriver to unfasten the screws and separate the fan from the cage. Clean the interior of the cage using a vacuum cleaner.

Clean up the fins

The AC fins will build up a lot of dust over time. Clean them by blowing water from a hose through them. Do not use a pressure washer as this will damage the fins. Blow the water from the inside out. There is a commercially available spray that is designed for the sole purpose of fin cleaning. Investing in this will also help. Finish the action by straightening any bent fins for the purpose of proper circulation of air. You can do this with the aid of a simple butter knife.

Clean around the Unit

Replace the fan cage and clean all around the AC. This will keep the cleaned debris from blowing back into the system. Balance the unit for the sake of keeping the compressor functional. You can also clean the evaporator coil using soft brush to dust it. You can also use a commercial cleaner to spray the coil and let the liquid dry off.

Finally, you can change the blower filter if damaged or too clogged. These can be obtained from your local hardware shop  Maintaining your AC ensures that it runs optimally for as long as possible. Experts will also clean and troubleshoot any looming issues. Get more info here.

The Need for AC Maintenance

HVAC Problems

Many homeowners fail to appreciate the need for AC maintenance in Philadelphia. Everyone wants a comfortable well-conditioned room but never put any efforts to ensure that the AC stays in a good condition. It’s until that moment when it breaks down, that we start putting it on top of our list.

Every AC loses a percentage of its efficiency every year. And with continuous use, its parts are bound to wear and tear and become weak. It also absorbs a lot of dirt and dust from the air. When there is huge dirt build up, it affects the functioning of the AC causing it to work harder. This will not only produce wear and tear but also affect the quality of air in your home.

Without regular maintenance to correct the small faults, the AC is bound to break down completely eventually. The best way to maintain your AC in a good condition is to look for an expert who will be giving it regular checks. With regular maintenance, you will avoid the following:

Costly repairs

If your AC is regularly maintained, you won’t have to worry about costly repairs. But when neglected, it will break down, and you will end up paying huge sums of money to get it working again.

Replacement costs

At times, the damage to the AC may be so extensive, that it can’t be fixed by repair. Or, you may be able to fix it, but then it keeps breaking down now and then. In such a happening you will have to invest in a new one. Most prominent and recurring issues arise from extensive wear and tear. So make sure you maintain it well to avoid losing a big investment before its expected life is over.

Health issues

When there is too much dust and debris build up, the AC will start blowing that into the air of your home. Dust and other harmful particles in the air will affect your family and pets especially those with allergies. So safeguard your health by having regular checks and cleaning. Call in a specialist who will open up the system and clean out the accumulated particles. Check over here.

Huge power bills

Without AC maintenance, your power bills are bound to go up. Even energy efficient ACs should be maintained. Otherwise, they will turn out to be very inefficient.

Have a piece of mind

AC maintenance will give you a piece of mind knowing that your air conditioner is in a good condition and not bound to break down anytime.

Maintenance Agreements Can Save You When it is 92 Degrees in Philadelphia

philadelphia maintenance agreement prevents problems

Philadelphia maintenance agreement prevents problems

The temp just hit 92 degrees, and the radio’s saying tomorrow will be hotter. Your three well-mannered children and their four not-so-well-behaved friends are playing inside because of the heat. And if that’s not enough, you notice your living room is 10 degrees hotter than it was two hours ago. You know it can’t be an A/C problem because your spouse promised you, five times, they’d have the unit inspected last spring.

Many things can cause havoc in your home … but don’t let it be a simple thing like neglecting A/C maintenance!

You’ve Got Choices for HVAC

Automate the Process

Our HVAC maintenance agreements mean we keep track of when your units are due for a check-up and call you to schedule. You no longer have to remember whether it was last April, or three Aprils ago, since your unit was serviced. Our agreements cover seasonal check-ups for your heating system, as well as A/C.

Hate Commitment?

Our one-time seasonal service call will verify that your unit is in tip-top shape to get you through the summer, whatever the weather brings. While what you really care about it that your home is comfortably cool, the details are that we’ll inspect your air filter, refrigerant pressure and all electrical connections, and clean your unit, including the condenser and evaporator coils and condensate drain.

Do It Yourself

If you enjoy outdoor tasks, these tips will make your unit more efficient and prolong its life. Keep it clean: wash your outside condensing unit regularly with a water hose and clear away leaves and other debris that could impede air flow. Change your filters every month: filters have a maximum lifespan of only three months and new filters make your unit much more efficient.

Save Your Money, Your Vacation & the Planet

  • Although our replacement units are among the most reasonable in the area, protect your summer budget. We don’t want you to spend your vacation savings on an emergency replacement A/C unit. Your existing unit may have lasted a few more years with proper maintenance.
  • Well-maintained units use less electricity. You can think of many fun ways to spend the dollars you save on your power bill.
  • Clean, efficient units produce much less pollution.

Major things we can’t control will always happen … your home being unbearably hot in the summer or cold in the winter isn’t one of them. Let us help you mark these items off your “worry” list.

Philadelphia HVAC Maintenance Tips

If you’re a Philadelphia homeowner, you don’t need to be told that an air conditioning system is expensive to purchase and have installed. It is because of this expense that many Philadelphia homeowners wait until the last possible minute to get rid of an old one. Routine air conditioning maintenance is the surest way to keep your Philadelphia HVAC system efficiently operating for as long as possible.

You can keep outright replacement of your Philadelphia HVAC unit to a minimum by being mindful of important routine maintenance. Being conscientious about maintaining your HVAC system can, not only keep it running at peak efficiency, it can also extend its lifespan.

We’ve all been told to change the air filter every month. The cleaner a filter is, the more efficiently your HVA system will work. During periods of heavy use, air filters become clogged with dirt and debris much more frequently. Try to check your air conditioner’s filter and replace it with a new one at least once a month. The natural lifespan of a filter is no longer than three months. When replacing a filter, be sure to buy the brand recommended by the manufacturer of your ac system.

It’s important to make sure that your outdoor condensing unit is kept clean. Wash it down regularly with a hose, and be sure to pick out any leaves, dirt, or other assorted debris that might interfere with the flow of air through your Philadelphia HVAC system. You should also clean the coil from time to time, using a soft-bristled brush to avoid damaging it.

If your air conditioning unit isn’t running properly, call Good Deals Heating & Air, a Philadelphia HVAC contractor, as soon as possible. Continuing to operate a malfunctioning unit may exacerbate current problems and lead to additional ones, which means that you’ll wind up paying for even more extensive repairs in the future. It’s also a good idea to have your air conditioning system inspected by a professional after a season of heavy use, to ensure that it continues to work well the next time you need it.

We can help you beat the heat this summer. We have the experience, skills and tools to fix these Philadelphia HVAC problems the first time.

Improve Air Conditioning System to Lower Philadelphia Electric Bill

Philadelphia Air Conditioning Repair

Philadelphia Air Conditioning Repair

One reason for high energy bills is an increase in the price of electricity or heating fuel. However, it is common to trace high energy bills to an in-efficient component (windows, heating and cooling equipment, ducts insulation) of your home or a failure of one of these components. It is not always easy to pin-point the problem, but fixing it can make your home more energy-efficient and comfortable.

When you need to replace your HVAC equipment, a high efficiency furnace, air conditioner, or geothermal system can save you money on your energy bills, and is a good idea.

Duct Systems lose energy causing high electric bills.  So you replace your 60% efficient furnace with a new 90% model, and you expect to save about 30% on your gas bill. Don’t bet on it! Your furnace is 90% efficient in a laboratory, but if it’s connected to a duct system that’s only 70% efficient, your “system efficiency” drops to 63%, a gas usage savings of only about 21%! But you paid for a 90% efficient unit and 30% energy savings.

The U.S. Department of Energy states that “typical duct systems lose 25 to 40% of the heating or cooling energy put out by the central furnace, heat pump, or air conditioner. Duct repairs could be the most important energy improvement measure you can do…”

Duct systems have tremendous pressures, both positive (supply duct) and negative (return air duct), exerted on them by the furnace blower when the furnace or air conditioner is operating. That means that air from unconditioned areas, such as an attic, crawlspace, unfinished basement, or garage can be pulled into a home or building through the return air duct, or pushed into an unconditioned area through the supply duct at a very high rate of speed. Imagine pulling 125 degree Fahrenheit attic air into your air conditioning system, and trying to cool it to 75 degrees.

To improve the energy efficiency of your home’s air conditioning start with these two tips.

  • Improvements may include sealing air leaks, adding insulation or sealing duct air leaks. Do not try to seal a duct system without advanced certified training and proper sealants. Dangerous or fatal conditions can result, including carbon monoxide poisoning and sealant off-gassing.
  • Install a programmable thermostat, and use it to save energy while you are away at work.
