How to Tell if the AC Is Leaking Refrigerant and Needs Repair

Responsible for absorbing and releasing heat, refrigerant is central to the operation of air conditioning systems. A refrigerant leak can significantly impair the system's performance, leading to additional issues. This blog outlines the common signs of a refrigerant leak and their causes.

Frozen Evaporator Coils

Frozen evaporator coils are a common issue in HVAC systems. When a leak occurs, refrigerant levels drop, resulting in insufficient refrigerant to absorb indoor heat adequately. This decrease in system pressure causes the evaporator coil to become too cold. 

Consequently, moisture in the air freezes on the coil, leading to ice build-up over time. This reduces both airflow and system efficiency, resulting in higher energy bills. Operating with frozen coils can also damage other components, such as the compressor. To fix this, a certified technician should promptly repair the leak and provide proper refrigerant recharge. 

The AC Is Not Cooling Properly

bills If the AC system is not cooling as effectively as it used to, one potential culprit could be a refrigerant leak. Refrigerant plays a critical role in the cooling process. It circulates through the system and absorbs heat from the indoor air, transferring it outside.

When there's a leak, the refrigerant level drops, leading to several noticeable effects:

  • Warmer Air from Vents: Low refrigerant levels reduce AC efficiency, leading to warmer air and difficulty cooling.
  • Longer Cooling Cycles: To compensate for the reduced cooling capacity caused by a refrigerant leak, the AC may run longer or cycle on more frequently.
  • Increased Energy Bills: Due to the longer and more frequent cooling cycles, the energy consumption of the AC system rises noticeably. 

If there’s a leak, contact a qualified HVAC technician to diagnose and fix the problem right away. They can recharge the system with refrigerant, ensuring efficient AC operation.

Unusual Sounds

sounds When unusual sounds such as hissing, gurgling, or bubbling come from an air conditioning system, it may signal a refrigerant leak. Here’s why these sounds might occur:

  • Hissing Sounds: This sound typically occurs when refrigerant escapes from the system, especially if the leak is coming from a small hole or crack in the refrigerant lines.
  • Gurgling Sounds: As the refrigerant leaks, air might enter the system, forming a mixture of air and refrigerant within the lines. 
  • Bubbling Sounds: The presence of air allows bubbles to form within the refrigerant, and as these bubbles circulate through the system, a bubbling noise may be heard. 

When these sounds are detected, an HVAC technician must inspect the system promptly. Identifying and fixing a refrigerant leak early can prevent more serious problems and keep the indoor environment comfortable.

3 Common Plumbing Mistakes To Avoid in the New Year

Plumbing Tools and Parts

Don't Fall Victim To These Common Plumbing Errors This Year!

Every year, countless homeowners face many plumbing issues, from minor clogs to major leaks and everything in between. But what many homeowners don't realize is that most of those issues are preventable. And when people take the wrong approach in trying to fix them, they can make matters much worse. But a general awareness of what to do - and more importantly, what not to do - will help set up homeowners for success in the new year. Keep reading to learn a few of the most common mistakes every homeowner would do well to avoid this year!

Mistake #1 - Using Chemical Drain Cleaners To Fix Clogsliquid drain cleaners

Whether it's a toilet, sink, tub, or shower, a clogged drain is a frustrating and unpleasant problem to have. Chemical or liquid drain cleaners are marketed as easy, quick fixes, making them highly appealing when nasty water is pooling up in the drain. To be sure, these products do get results in some cases by causing a chemical reaction that dissolves or eats away at the obstruction in the pipe.

The trouble is the same chemical reaction can also harm the plumbing itself, damaging pipes, marring fixtures, or interfering with the natural biological processes that septic systems rely on. This is especially true if these products are used repeatedly - which is often the case, as they don't always clear up the root cause of the problem. They can also produce harmful gasses and cause serious burns on contact with bare skin.

In general, the risks of chemical drain cleaners outweigh the rewards. Instead, it's better to resolve drain clogs with safer and more effective methods such as snaking or hydro-jetting and rely on preventative drain maintenance (i.e., routine drain cleanings).

Mistake #2 - Neglecting Water Heater Maintenance

The water heater is an indispensable component of any home's plumbing system - at least, as far as comfortable showers and effective dishwashing are concerned. But not everyone realizes that water heaters require a good deal of maintenance to run properly and last as long as intended. Homeowners who don't keep up with their water heater's maintenance requirements usually find themselves shelling out for repairs - or a whole new water heater - before long.

A routine water heater service visit will typically include:

  • Draining and flushing the tank to remove any sediment buildup
  • Cleaning gas burners and exhaust vents
  • Testing electrical components and safety devices
  • Ensuring that the unit isn't being damaged by corrosion

These tasks - generally performed once a year - are imperative for ensuring the unit's safety, longevity, and efficiency. Neglecting or putting them off is a recipe for trouble!

plumber Mistake #3 - Not Calling a Pro for Repairs and Installations

Many homeowners are tempted to fix the problem themselves when something goes wrong with the plumbing system, whether it's a clog or a leak. This may be perfectly appropriate for a minor clog or a dripping faucet, where the fix is as simple as working the plunger or replacing a gasket - but it's much better to let the majority of plumbing repairs a professional plumber handle it.

A pro not only has the right tools and skills for the job, but they can also ensure that all repairs are performed safely and according to the latest codes and standards. Moreover, a professional can identify the underlying cause of an issue to ensure that the solution isn't just temporary. For instance, they can determine whether a small leak is an isolated problem or has been caused by a larger issue such as erosion or overpressurization and adjust their repairs accordingly.

The same goes for installing new fixtures or appliances. A well-meaning DIY'er may be able to get the job done, but only a professional can ensure that it gets done correctly to avoid further issues down the road. Improper installation can dramatically shorten the lifespan of water heaters and other fixtures. Especially for major plumbing installations, it's always best to hire a pro.
