Sounds That Can Mean It’s Time for Air Conditioning Repair

Friday, September 5th, 2014

One of the easiest ways to tell that it’s time to call an expert for air conditioning repairs is if you hear unusual sounds from your air conditioner. You’re used to the sounds of the compressor starting outside and the familiar humming noise indoors, but anything strange can signal trouble. Don’t ignore the warning signs of a failing system. Even a small repair can cause big problems for other parts of your air conditioner.

Here Are Some Troubling Sounds to Listen for That Indicate It’s Time to Repair Your Air Conditioner

  • Hissing: A hissing noise may indicate a refrigerant leak. Refrigerant is a chemical blend that continuously cycles through your system whenever it is turned on. Refrigerant actually absorbs the heat from your home, which is how the air is cooled. And while the heat dissipates outdoors, the refrigerant will not—unless there is a leak. Without refrigerant, your home may never reach the desired temperature, and other important components of your system may suffer as well.
  • Banging/Clanking: A loud banging or clanking noise can have many different sources. A loose, bent, or otherwise damaged fan blade from the indoor or outdoor fan may bang against the inside of the unit, causing wear and tear to your system and inhibiting the airflow that is necessary for heat exchange. The banging noise may also indicate compressor damage, which requires the immediate attention of an air conditioning technician.
  • Buzzing: A buzzing sound often indicates an electrical problem, such as a problem with the wiring, the motors, or a capacitor. A loose contactor may affect the capacitor, so that the motors in your system do not receive enough electricity to operate properly. You should not attempt to diagnose or fix an electrical issue on your own.

While this list can give you a good indication of what a noise may mean in your air conditioning system, you should allow a professional to pinpoint the problem. Do you need air conditioning repair service in Mesa? The experts at Johns Refrigeration are trained to recognize repair needs and find the source of the problem to get your air conditioner running like normal. Give us a call today!

3 Problems Caused by Leaky Refrigerant

Friday, August 22nd, 2014

One of the essential components that makes an air conditioner work is refrigerant, a chemical blend that courses through the cooling system and changes from gas to liquid and back again. As the refrigerant absorbs and releases heat, it moves heat from the inside of a home and deposits it outside. This is calledheat exchange, and it’s the secret to how electro-mechanical air conditioning works.

During heat exchange, the amount of refrigerant inside an AC doesn’t lower. As long as the system is working normally, the air conditioner will not lose of its charge of refrigerant. However, the charge can drop if leaks develop along the refrigerant lines or inside the compressor. Loss of refrigerant is a serious repair problem that will impair an AC and possibly cause it to break down permanently if not dealt with.

If you notice a loss of cooling from your AC or hear an unusual hissing noise coming from its cabinets, call Johns Refrigeration right away. Since 1970, we’ve handled air conditioning repair in Scottsdale, AZ that keeps customers coming back to us.

Here are the troubles you may encounter with your AC due to leaking refrigerant:

Loss of Cooling/Rise in Bills

With less refrigerant inside an air conditioner, the balance of heat exchange will weaken. The indoor evaporator coil will be able to absorb less heat, and the outdoor condenser coil will be able to exhaust less heat. The air conditioner as a whole will start to lose its cooling power, and consequently it will strain harder to reach its target temperature, leading to a spike in electrical bills.

Ice along the Evaporator Coil

One of the major warning signs of leaking refrigerant is ice and frost developing along the indoor coil. Although it might seem strange that losing refrigerant would cause ice to appear, the reason this happens is that the remaining refrigerant in the coil doesn’t warm up enough, and the cold along the coil will start to freeze the water vapor in the air. This creates a downward spiral, since ice will further prevent the coil from absorbing heat, leading to more ice. Eventually, a solid ice block will form over the coil and prevent any heat exchange from occurring.

A Burnt-Out Compressor

This is the most serious consequence of a loss of refrigerant: if the compressor burns out, usually the entire air conditioner will need replacement. The danger to the compressor is that a reduced level of refrigerant inside it will cause it to overheat, eventually melting its wiring and ruining it. For this reason, you cannot delay when you notice any sign of lowered refrigerant.

One way to avoid the troubles from refrigerant leaks is to enroll your AC in a maintenance program. During a yearly inspection, a technician will check the refrigerant level to make sure that it hasn’t lost charge. If there are leaks, the technicians will locate and seal them, and then recharge the refrigerant to its proper level.

When you need air conditioning repairs in Scottsdale, call up the experienced team at Johns Refrigeration. We will have your cooling restored in no time.

Can I Run My AC with Low Refrigerant?

Friday, August 15th, 2014

The refrigerant in your air conditioning system facilitates the transfer of heat from your indoors to the outdoors. Every air conditioner is manufactured to operate with a specific amount of refrigerant. This specific amount is added to your system during installation, and decreases only if a leak occurs in the system. When an AC’s refrigerant level is off – either too high or too low – system-wide problems will develop that can affect many different aspects of your cooling. It may take a while to notice these problems, but one thing to know about refrigerant leaks is they don’t go away on their own. No one wants to think about needing air conditioning repairs during August, but when it comes to low refrigerant, it’s necessary to call professionals, like the ones here at John’s Refrigeration.

Problems Caused by Low Refrigerant

There are multiple problems that can be caused by low refrigerant:

  • Decrease in cool air – as we mentioned above, refrigerant facilitates the transfer of heat in the air conditioning cycle. When this process becomes unbalanced due to a leak, the refrigerant can stay too warm, disabling it from achieving the cooling needed for your home.
  • Ice formation – when the refrigerant level is too low, the warm parts of your system stay too warm, and the cool parts get too cold; this creates condensation that, because of the cold parts, freezes over and forms ice. Scraping the ice off does not repair this problem; it requires professional repair for the refrigerant leak.
  • Compressor problems – your compressor is made to operate with the exact amount of refrigerant needed for your system. When too little refrigerant enters the compressor, it can malfunction in a few ways, including overheating and breakdown. Compressors are complex to repair and even more expensive to replace, so it’s best not to risk this by running your AC with low refrigerant.

Refrigerant Repairs Need Repair

Refrigerant leaks can throw off your entire system, and it’s important to hire professionals to fix them. Why? It can be difficult to find a refrigerant leak, and you need to be certified to handle refrigerant. If you suspect you may have a refrigerant leak and require repairs, call John’s Refrigeration to set up your air conditioning repair service in Phoenix today.

3 Common Compressor Repairs

Friday, August 8th, 2014

There are 3 main components to your air conditioner: the condenser, the evaporator, and the compressor. Each is important to the function of your air conditioner, and each has different responsibilities. There are a few common problems that occur with compressors that can create a need for air conditioning repairs. One thing to keep in mind is that the compressor is a complex component, so you should always call a professional like the ones at John’s Refrigeration to conduct AC repairs in Queen Creek.

Here’s a List of Common Compressor Problems

  • Motor issues – if your air conditioner is short-cycling, it can cause your compressor to overheat or even burnout. This can also happen if something like a faulty thermostat is constantly triggering your system to turn on and off. Motors can sometimes be repaired, but in cases of burnout, they usually need to be replaced.
  • Low refrigerant – your compressor isn’t the cause of low refrigerant, but it can suffer problems when this happens. Why? Your AC runs on a specific level of refrigerant; when the level is lower than it should be, the entire heat release/cooling process is thrown out of balance. This is a problem for your compressor because the refrigerant needs to be in certain states – gas or liquid – when it enters different parts of your system. When it comes to your compressor, the refrigerant needs to be a cool gas, but sometimes, when the refrigerant is low, it may enter as a liquid. Your compressor wasn’t made to work with liquid refrigerant, and will most likely break down in this scenario. A second problem with low refrigerant is that too little refrigerant is being pressurized, which can cause your compressor to overheat.
  • Electrical issues – wires throughout your system can corrode, fray or disconnect, and this includes the parts in your compressor. One common sign of an electrical issue is “hard starting” – a noticeable stuttering when the compressor motor turns on.

Your compressor is a complex component, which is why it’s important to call a professional when you need compressor repairs for your air conditioning. John’s Refrigeration has been helping customers in Queen Creek, AZ since 1970, so if you have a problem with your AC’s compressor, call us today!

Air Conditioning Repair in Gilbert AZ: Heat wave problems that could have been prevented

Thursday, June 12th, 2014

With temperatures already reaching over 110, a/c units in need of repair are starting to strain to cool our homes. If there’s another heat wave like we had during 2013, things could get even worse. Before you need to call John’s Refrigeration Heating and Cooling for your air conditioning repairs in Gilbert, AZ this summer, consider preventive maintenance so that you and your family are cool all summer long.


In the Southwestern United States in late June/early July last year, seven people died in the Arizona desert from dehydration and exhaustion due to the intense heat when temperatures hit 120°. In fact, it was so hot here that tigers at the Phoenix zoo were served frozen fish treats and butterflies were found collapsed on the pavement due to the high temperatures. Mesquite trees even close their leaves to protect themselves during extended periods of extreme heat, though mesquites are native to the desert.

Keeping you’re a/c unit maintained means you won’t have to worry about it shutting down when temperatures rise to uncomfortable levels. Although it’s great to have a reliable HVAC company like John’s to call when you need a/c repairs or even a new unit, it would be even better if you didn’t need to call them at all and could just not even worry about problems like your air conditioning not working.

If you are not fond of frozen fish treats and you prefer not to collapse on burning pavement, perhaps you should think about calling John’s Refrigeration to make sure your HVAC unit is running at maximum efficiency. Even our name sounds refreshing with temperatures this high.

Plan for Air Conditioning Repair Services Now

Wednesday, April 30th, 2014

Arizona’s summers are nothing to sneeze at and without a reliable air conditioning system, your house could quickly turn into a sauna when the temperatures start to rise. Here in Mesa, air conditioning repair services need to be on the ball and ready to go at a moment’s notice, but it helps if you the homeowner can anticipate and prepare for the kinds of problems that repair technicians face. The spring is an excellent time to start that process, and if you plan for air conditioning repair services now, you can save yourself a lot of grief later.

One of the best ways you can do that is to schedule an air conditioning maintenance session, in which a trained expert examines the system for any potential problems. That helps you get a jump on lingering issues before they disrupt your service, as well as letting you schedule the repair session at leisure, before the heat of summer hits and you need the problem to go away as quickly as possible. Maintenance sessions also clean up dust and repair any loose bolts or fittings, which improves the unit’s efficiency and helps save money on monthly utility bills.

Another good way to plan for air conditioning repair services is to perform an energy audit on your home and look for ways to improve its efficiency. For example, you may be able to add more insulation to help retain cool air better, or patch up cracks under your doors or windows with the use of weather stripping. Not only will it make your home more comfortable, but it will reduce the strain on your air conditioner, lowering the chances or a major repair session.

If you plan for air conditioning repair services now, you’re not necessarily eliminating all chances of a breakdown, but you are ensuring that such repairs are less likely to raise their heads. And if you do it in the spring, before the heat index starts to rise here in Mesa, air conditioning repairs don’t become the emergency that they might otherwise. For more on how you can get a jump on trouble this summer, give the Mesa air conditioning repair experts at Johns Refrigeration a call. You’ll be glad you did!

Are You Getting Ready to Turn on Your Cooling System?

Friday, April 4th, 2014

Right now, spring is treating us to warm and pleasant weather in Mesa, AZ. You may have already turned on your home’s cooling system, whether switching the heat pump to “cool” or activating the central air conditioner, for a few days. However, the real heat is lurking right around the corner, and that’s when your air conditioning will truly begin to earn it keep for the year.

Summers in the Valley of the Sun can turn brutal. We have some tips from HVAC experts to help make your transition into full-bore air conditioning mode go with as few troubles as possible.

Johns Refrigeration is here to help you switch to the summer heat. We have a maintenance program to prepare your system, and offer air conditioning repairs in Mesa, AZ for those times when the best preparations can’t stop malfunctions.

Here are a few things to consider before your AC comes on for the season

  • Schedule regular maintenance: You should always have a maintenance technician inspect your air conditioning and give it a tune-up once a year, and spring is the best time to have the work done so the system will be in top condition for the summer heat. An air conditioner running at its best will also operate without cost overruns, keeping your electric bill from making abrupt spikes.
  • Handle any repair needs: A maintenance check will identify places where you air conditioner should have repairs done before turning on for the season. You may already know about possible malfunctions because of unusual behavior from the unit (strange noises, a drop in airflow). Don’t procrastinate about scheduling the work to fix these problems: getting trapped in the summer heat waiting for repairs for a broken unit is no fun.
  • Change the air filter: This is a part of air conditioner and heat pump maintenance you can do on your own. The air filter that protects the inside of the system from damage will develop dirt and dust clogs while it works, and unless it’s changed regularly for a clean filter, it will start to cut off airflow and permit particles to enter the cabinet. During cooling season, you should change the filter once a month.

Start with maintenance

An annual maintenance program is the best way to protect your home’s cooling (as well as your budget). Call Johns Refrigeration and join our Peak Performance Club. Membership grants you priority scheduling and special discounts. You can select different levels of membership depending on your needs and budget.

Make sure you enjoy a cool summer in Mesa, AZ with air conditioning repair and maintenance from Johns Refrigeration.

Common Air Conditioning problems

Monday, November 4th, 2013

When you run your air conditioning system as much as we do here in Arizona it can develop several common problems. Here a John’s Refrigeration we offer a full range of air conditioning repair services in Mesa, AZ for many different types of cooling systems. We’ve been in business since 1970 and we wanted to share some of the most common problems that we see. Give us a call today and one of our NATE-certified air conditioning technicians will be able to help you with any services that you need.

Air Conditioner Repair Tips: Common Issues

Here are a few o of the most common problems that homeowners face when it comes to their air conditioning systems.

  • Not enough cooling – We often get calls from homeowners who say that their AC is blowing warm air or that their home isn’t getting cool enough. This could be caused by low refrigerant in the system, a broken compressor, a bad fan motor or a clogged air filter.
  • Noises – When your air conditioning system starts to make strange noises it’s time to call for Mesa, AZ air conditioning repair services. Your AC has a number of moving parts and if they break down they will start to make noise. Squealing usually indicates that the fan motor belt is bad. Hissing often is a sign of a refrigerant leak and gurgling can mean that you have low refrigerant.
  • Clogged air filter – Probably the most common cause of air conditioning repair is a clogged air filter. If your AC’s air filter gets clogged with dust and dirty it will restrict the flow of air through the system. This could lead to insufficient cooling, increased repair, decreased efficiency and much more.
  • AC won’t turn on – If you air conditioner won’t turn on then you have a big problem. But sometimes this could be something simple like the AC has become unplugged. But it often is more serious than this. It might be that the motors’ capacitors are bad, that the motors themselves are broken or that the thermostats in your home need replacing.
