Three Symptoms that My System Might Have a Leak

May 10th, 2014

How can you tell if your HVAC system is leaking?
And what are the options for fixing each?

There are three kinds of leaks in an HVAC system, and none of them are good.


If you ever see water around your home’s indoor a/c unit, it’s a sign that something is either dripping, leaking, or not draining. Three main reasons an a/c system leaks are if there’s a crack or hole in the overflow drain pan, the air filter is clogged with dirt, or the condensate line is plugged up.

The water may also be caused by a cracked condensate pan, trap, or drain, a damaged condensate pump, dry-rotted, cracked or kinked furnace tubing or condensate parts, or the drain line has moved and is no longer pitched downward.

Refrigerant (such as Freon)

Refrigeration systems are sealed and don’t use up refrigerant. So if you had a refrigerant leak, recharged the system with additional refrigerant, but fixed nothing, you still have a leak. A system running low or near empty on refrigerant is quite harmful to your compressor and could damage the entire system.

There are many signs your system could be experiencing a refrigerant leak, including if your house takes longer than normal to cool off or the supply ducts/registers are blowing hot air even when your a/c is running and your thermostat is set to “cool.” We discuss in more detail the problems and solutions that leaking refrigerant can cause in our blog, “Should I Have to Add Refrigerant to My System Every Year?


If your system is leaking air, however, most air leaks can be traced to the equipment or ductwork, which can easily be found and repaired. Since ducts are often damaged when people come in contact with them, especially during home repairs, major or minor leaks can occur. Any major damage may require replacement of sections of the ductwork, but minor damage might be able to be sealed using sealant or metal tape. Leaky ducts can waste hundreds of dollars each year and should be repaired or replaced as soon as possible.

Bottom line, your HVAC unit should not be leaking water, refrigerant, or air. Just call John’s so we can test your system to see where any problems are. We’ll give you options so your unit or its parts can be repaired or replaced and you can get back to enjoying the comfort of your own home again.

Consider joining our Peak Performance Club and get two inspections every year to identify anything that could shorten the life of your system, including checks for leaks.

Why Dripping Water Is a Problem With Your Air Conditioner

May 8th, 2014

You need a reliable cooling system when summer rolls around, and here in Gilbert, AZ, air conditioning systems are as common as televisions and refrigerators in most homes. It behooves you to check your system for potential problems regularly and more importantly, to understand which signs indicate a need to summon a repair service. Dripping water, for instance, may not seem like a major cause for concern, but it can often indicate a significant issue.

Here’s Why Dripping Water Is a Problem with Your Air Conditioner

Dripping water usually stems from one of two serious issues. The first is a build-up of ice on your evaporator coils, representing lost cooling potential and insulating the refrigerant from the air it is supposed to cool. That’s usually caused by a loss of refrigerant, which needs to be corrected before it can cause even bigger problems.

A second cause can come from problems with the condensate pan, which collets condensation from the system and moves it safely out of your air conditioner. If the line gets clogged or the pan itself is misaligned, the water could overflow and create puddles on the ground.

In both of these situations, the dripping water constitutes a significant threat to the system. Air conditioners utilize a number of electrical components, including the condenser motor and fan motor. Dripping water can short them out, shutting your system off and necessitating some very expensive replacement parts. The good news is that a qualified AC repair technician can usually fix the problems before they get out of hand, either by sealing the leak, recharging the refrigerant, unclogging the drain line or fixing the misaligned pan.

That means, however, that you need to understand why dripping water is a problem with your air conditioner, and respond appropriately when you spot it. Air conditioning repair services in Gilbert, AZ are provided by the cooling experts at Johns Refrigeration. We pride ourselves on efficient service and our trained technicians know how to get to the bottom of any problems quickly. Contact us today to set up a repair appointment. You’ll be glad you did!

Annual AC Maintenance: Should I have to add refrigerant to my system?

May 6th, 2014

Contrary to popular belief, HVAC systems do not use up refrigerant (a common brand of refrigerant is Freon). Your HVAC system is designed to run with a specific amount of this refrigerant. Freon is a liquid agent that cools and dehumidifies indoor air and isn’t ever “used up” like a car uses gas or oil. It just circulates around your a/c system to cool your air; no refrigerant is lost in the process.


Some homeowners believe their a/c unit needs to be recharged with refrigerant, but that is not generally recommended, as there may actually be a leak in the unit causing the air conditioning problems. If the leak isn’t repaired, the unit will continue to leak refrigerant, even if it’s recharged. If refrigerant is low, that means it has a leak. Low refrigerant charges can damage your compressor and your coils because if they freeze up, the ice can cause cracks to form in the coils, which causes more leaks.


A properly charged HVAC system will work better and cost less to operate, which is why annual a/c maintenance is recommended. If your HVAC system is not keeping your house as cool as you want it, here are signs to look for that will tell you that your a/c unit may be running low on refrigerant due to a leak:

  • Supply ducts/registers are blowing hot air even when your a/c is running and your thermostat is set to “cool”
  • Water has accumulated on the floor by your furnace due to condensation
  • Ice has built up on copper lines from a/c to indoor coil
  • High electric bills (because your air conditioner has to run longer to cool your home)
  • House takes longer than normal to cool off

Annual a/c maintenance will discover things like leaks and low refrigerant levels, and you should never attempt to recharge the refrigerant yourself, no matter how handy you are around your home. You need to have an EPA license to buy R-22, the most common refrigerant, and you need the proper tools (gauges, scales, etc.), which can be expensive. R-22 is now being done away with, which is making it more expensive; R410A is in all systems in the last five years. Because of this, older systems that take R-22 are often less expensive to replace than to repair.

There are also strict EPA regulations against doing it yourself. Just call John’s if you are experiencing any of these low refrigerant signs and we will inspect the entire HVAC system and offer solutions to keep your family cool.


Why is it important to regularly change air filters for home?

May 1st, 2014

All of the air that flows from your HVAC unit into the living spaces of your home must pass through an air filter before it gets to the air conditioning or heating unit. If the filter is clogged with contaminants, the air will filter through those pollutants as well. Air filters for home don’t just help improve the air quality inside your home, however; they also protect your heating and cooling system from being damaged. The Environmental Protection Agency cites changing your home’s air filter as the most important maintenance task that you can do to optimize your HVAC system’s energy efficiency.

By changing the air filter in your home, you’re not just allowing the unit to breathe easier; you are also doing the same for your family.


There are a host of health problems that can occur as a result of airborne contaminants inside your home. Change your air filters on a regular basis to keep your home comfortable and to avoid the many respiratory difficulties, allergies, and illnesses that can occur because of the circulation of bad air in your home.

Most air filters trap contaminants including dust mites, tobacco, bacteria, dust, pet dander, pollen particles, and particles that carry viruses, which can help keep your family healthier, too. The amount of contaminants captured by the air filter increases over time and it will eventually become so dirty that it will restrict airflow. The HVAC system is then forced to work harder to move the amount of air necessary to maintain the desired temperature in your home. The amount of additional energy your unit has to draw under these conditions is significant and often results in higher utility bills.

Buying the correct size filter is also important; you want the air to move through the filter, not around it. Please read our article on what type(s) of filters to use. Change the air filter on a regular basis in order to keep your unit working as efficiently as possible. Air filters should be replaced (or at least checked) every month, especially in the winter and summer when your system is used the most.

In order to get the most efficient use of your system, change your air filters regularly in order to enjoy the coolness of your home when temperatures reach 110°. It’s the easiest, yet most important way to keep your HVAC unit running efficiently and keep it running when you need it.


Plan for Air Conditioning Repair Services Now

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!

5 Ways to Make Every Day Earth Day in Gilbert Arizona

April 29th, 2014

Even though Earth Day was last week, Gilbert Arizona is a great place to make every day Earth Day. From the 350+ days of sunshine to the hiking trails, there are opportunities to enjoy the outdoors year round. Being in the desert makes us more conscious of our water use – or it should – and we can all save a little on summer utility bills while helping the environment.

Here are five ways to make every day Earth Day in Gilbert Arizona:

  1. Go outside. There’s nothing better than the sun shining on your face. Enjoy the outdoors by taking a walk with a friend or play outside with your family. Take advantage of the near-perfect weather we have here in Arizona!
  2. Use less water. Turn the tap off when you’re brushing your teeth. It saves as much as four gallons a minute!
  3. Save electricity. Turn off lights when you leave the room. Cover south facing windows. They get the most sun throughout the year, heating up your home, and causing the A/C to run non-stop.
  4. Use reusable grocery bags. The average family visits the grocery store more than once a week. That makes for a lot of plastic and paper bags going to the landfill. Opt instead for reusable bags and make it ZERO bags going to the landfill.
  5. Hang clothes outside. There’s almost nothing better than the smell of clean sheets. Hanging clothes and linens outside saves the energy you would spend using the clothes dryer. And in Arizona, laundry doesn’t take long to dry!


Imagine how great a world it would be if we each made one small change to make every day Earth Day! If you’d like to learn about even more ways to save energy and money, read our blog, 10 Ways to Save Energy in Your Home.

What Are Some Signs That I May Need a New Air Conditioning System?

April 22nd, 2014

If you require new air conditioning installation, now is the ideal time of the year to have the work done. You’ll have your new system humming away at keeping you cool in time to keep back the Arizona summer heat. Just make a call to Johns Refrigeration and tell our skilled technicians that you want new air conditioning system installation in Gilbert, AZ, and we’ll help you find the right AC to replace your old one.

However, you may feel unsure if you need to have a new AC. Replacing an air conditioner is a large task, and sometimes targeted repairs are a less expensive option. We’ll look at signs that usually indicate when repairs are no longer the best choice and it’s time to replace.

Signs it’s time to retire that old air conditioner

  • Rising repair costs: How much is too much when it comes to repairing an air conditioner? Take some time to look over the last two years of repair bills for your AC (cooling systems tend to need the most repairs during their last two years of operation). Add them up. If you discover that it takes more than $500 in repairs per year to keep your AC running, then it’s no longer worth the cost of maintaining the system and you should look into new installation.
  • Reduced cooling power: If the summer comfort in your home just isn’t what it used to be, you should take into account the age of the air conditioner. The life expectancy of most AC systems is 10–15 years; check the cabinet or the manual to find out the estimate for your system. If your air conditioner has reached this age and you notice a drop in cooling power, then it’s time for a replacement.
  • Increased operating costs: You may not need numerous repairs for your air conditioner, but an old one can still cost you extra money through inefficient operation. Examine your electric bills for the past two years to see if you spot a noticeable rise due to the AC. If you’ve kept up regular maintenance on the system but operating costs continue to rise, then the air conditioner has probably reached the point of no return and needs to retire.

A professional second opinion

You do not need to make the choice of “replace or repair” on your own. Call a skilled HVAC repair technician to examine the system and give you an honest opinion on how much longer it will last and what you can expect to pay to keep it running. If it turns out that replacement is the most economical option, the technician will help you select a new system and schedule the installation work.

At Johns Refrigeration, our family-run business has helped customers since 1970 keep cool. Look to us when you need information about air conditioning installation in Gilbert, AZ and whether it’s time for you to replace your old system.
