Why Can’t You Just Recharge Low Refrigerant Levels?

Monday, August 17th, 2015

Most people know that air conditioners run on refrigerant, a chemical combination that encompasses a number of specific names and formulas. The specific type and amount of gas depends on the make and model of your air conditioner, but all refrigerant has a few things in common: a relatively low vaporization point, an ease of shifting from liquid to gaseous form and back, and the ability to pull heat energy from the nearby air in the process. It’s what makes air conditioning possible, and has proven to be a revolutionary technology in hot cities like Mesa, AZ. (more…)

What Happens When Refrigerant Leaks?

Monday, June 29th, 2015

Refrigerant leaks and low refrigerant levels rank among the most common reasons to summon an air conditioning technician. Theoretically, your air conditioner runs its refrigerant through a closed loop: shifting it from a gas to a liquid and then back into a gas, and pulling heat from the nearby air in the process. That depends on precise levels of refrigerant in your system (the exact amount depends on the system) and when it springs leaks, it can have a detrimental effect on your ability to cool the air. Here in Mesa, AZ, that’s a significant concern, especially in the height of summer. So what happens when refrigerant leaks? Nothing good. (more…)

Three Symptoms that My System Might Have a Leak

Saturday, 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.

Water

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?

Air

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.

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

Tuesday, 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.
