Refrigerant Leak

Refrigerant Leak

You are going to run into problems with your air conditioning system at some point. “Problems,” of course, is a very broad term. An air filter that is too dirty is a problem, but it is one that homeowners can pretty easily resolve on their own. A refrigerant leak, on the other hand, is a very serious problem. If you have any reason at all to suspect that you have a refrigerant leak, then you absolutely need to schedule professional repairs right away.

If you want the best air conditioning in Loveland, CO, then you need an air conditioner with the ideal amount of refrigerant in the system. It’s just that simple. Low refrigerant levels cause serious issues, potentially doing irreparable harm to systems. And refrigerant is not just something that you can top off,  like the gas in your car, when it runs low—because it should never run low. More on that below. Let us handle your AC service needs.

What Does Refrigerant Do?

It is not an exaggeration to say that the whole operation of your air conditioning system hinges upon the refrigerant cycle. Without refrigerant, your air conditioner simply cannot cool your house! Your air conditioner does not generate cooled air out of, well, thin air. No, it removes heat from the air that is already in your home, and then redistributes that air back throughout the house. And it does so through the evaporation and condensation of refrigerant.

As the refrigerant evaporates in the indoor evaporator coil, heat is drawn out of the air. That warmed refrigerant then travels outside, where it is condensed, releasing its heat into the air outdoors. This cycle continues until your desired temperatures are met throughout your home. It’s a relatively simple process in theory, but a refrigerant leak can bring everything grinding to a halt.

Your AC Does Not Consume Refrigerant

That refrigerant cycle that we discussed above does not involve the consumption of refrigerant. Instead, the cycle continues over and over again in a closed system. That means that a decreasing level of refrigerant indicates a leak. Why is that such a major problem?

  • Low refrigerant levels lead to higher energy costs, as the system must run longer and longer.
  • Eventually, the system can start to short-cycle as it overheats, running in short bursts. This further raises operating costs.
  • Additionally, the system is put under a lot of excessive strain. This increases the risk of operational problems.
  • You’re now paying more money for less cooling, while also covering repair costs that could have been avoided.
  • Eventually, the compressor can seize up. At that point, you’ll probably be looking at a whole system replacement.

If you notice that your AC keeps developing ice, that it is short cycling, or that its cooling output is decreased, then you need to contact us right away. Don’t allow a refrigerant leak to take a serious toll on your home cooling system.

Heat Pump Problems

The heat pump is becoming a more and more popular option among homeowners in the market for new HVAC systems. It is not hard to understand why, considering heat pumps can function as effective air conditioners and also as highly efficient heating systems. What is a bit harder to understand for some users, however, is how this is even possible. The answer is that a heat pump is able to reverse its refrigeration cycle.

Because the refrigerant in these systems serves such an important purpose in both the heating and cooling process, it should be obvious that any issues with the refrigerant in the system are a serious problem. Refrigerant is not consumed by a heat pump, but rather operates in a closed loop and is just cycled through the system over and over. That means that low refrigerant levels indicate a leak, and that could spell big trouble for your heat pump in Loveland, CO.

 

How the Refrigerant Cycle Works

Refrigerant is such a great heat transfer fluid because it changes with ease from a liquid to a gas and back again. When cooling a home, refrigerant is evaporated in the indoor or evaporator coil. In a central AC this coil always performs this function, but heat pumps are able to flip the operation. As the refrigerant evaporates it absorbs heat from the air passing over the coil. Then it heads outdoors.

There, in the condenser coil, the refrigerant is condensed. This allows it to release its heat. The process is simply repeated over and over until the desired temperature is met. A heat pump can reverse the direction the refrigerant flows in, evaporating it outdoors and compressing it in order to heat a home. The warm refrigerant is then condensed in the indoor coil, which allows it to release its heat for use throughout the house.

Spotting Refrigerant Leaks

Have you noticed that your energy costs are starting to spike even though you haven’t been using your system any more than is normal? Is it taking longer and longer for your heat pump to adjust temperatures to the desired level, causing it to work much harder than it should have to? Is your system running in short bursts, overheating and short cycling? If so, then you may well have a refrigerant leak.

You may actually be able to hear refrigerant escaping from your refrigerant lines, as the pressurized gas can cause a hissing sound as it escapes the system. In the winter, your heat pump may ice over if refrigerant is low as well, and you may simply not be comfortable in your home.

Forcing your heat pump to run with a low refrigerant charge does not just result in decreased comfort and increased usage costs. It can also result in irreparable damage to the compressor. In that event, you’re likely going to be looking at a full replacement. If you suspect that you have a refrigerant leak, contact Fort Collins Heating & Air Conditioning right away.

We’ve dealt with this question before, but we hear it often enough that we want to address it now at the point of summer where it often comes up again. You do not need to add refrigerant to your air conditioning system before it “runs out.” This is a common misconception about air conditioner operation. Refrigerant is essential to how an air conditioner runs—it’s a chemical that allows the system to move heat from inside a home to outside—but it isn’t the energy source for the system and it isn’t depleted through normal use.

Fuel vs. Heat Transference Fluid

What is the fuel source for your AC? You know this already: electricity. This is what the AC consumes in order to run, and it’s what you pay for each month to continue to run the AC.

Refrigerant, on the other hand, is a chemical that’s designed to remain at the same level (charge) in the air conditioner for its entire lifetime. As the refrigerant moves through the system, going from the compressor to the outdoor coils and then the indoor coils, it goes through a process of condensation and evaporation. Its pressure rises and falls, it loses and gains heat, it goes from liquid to gas form and back again—and doesn’t dissipate at all during the process.

Adding Refrigerant Is an Occasional Repair Need—Requiring Professionals

The refrigerant charge of an air conditioner can drop, however, if the refrigerant lines develop leaks. Should this happen, you’ll notice signs such as a decline in cooling capacity, ice appearing along the evaporator coils, and a hissing noise from the cabinet. Arrange for air conditioning repairs with HVAC professionals right away. Not only does the proper amount of refrigerant need to be added (too much refrigerant is a bad as too little) the leaks must also be located and patched.

If you suspect your AC has lost refrigerant, turn to our technicians for air conditioning repairs in Loveland, CO.
