Identifying Air Conditioning Problems

Last summer, after carefully planning a family reunion for months, the worst thing in the world happened. My air conditioner died right in the middle of the night--when we had our entire family staying at our house. People were uncomfortable and grumpy because of the heat, and it was really embarrassing. Fortunately, we were able to get an HVAC contractor out to help us, and they did an awesome job fixing things fast. To prevent problems in the future, I decided that it would be smart to learn how to identify air conditioning problems. My website is all about finding the things that are wrong with your HVAC system and preventing issues.

Why Is Your Outdoor AC Unit Hissing?

If you notice loud hissing sounds coming from your outdoor air conditioner, you might think you have a large snake around your home. The hissing noises emitted by your outdoor unit may actually be due to a leak in your refrigerant (coolant) lines. Refrigerant lines can leak if they break down or crack from pressure. Low refrigerant can cause problems with your cooling system over time. Here are more details about your leaking coolant lines, including how to fix them. 

Why Are Your Coolant Lines Leaking?

Coolant helps remove or expel excess heat from your air conditioning system. The special fluid relies on special lines to travel through your air conditioning units. If these lines become broken, cracked, or aged beyond repair, they can leak. Without the proper amount of coolant, your indoor unit can freeze up and your outdoor unit can overheat.

You should have two copper-colored refrigerant lines extending from your outdoor unit. One or both lines should feature a layer of black insulation over them. Inspect the condition of the lines to see if they contain any cracks, rusted spots, or openings. Run the palms of your hands over the cracks or openings. If you feel cool air seeping against your palms, contact an air conditioning specialist like Always Ready Repair right away to repair the leaks.

How Do You Stop the Leaks?

Before an AC contractor repairs the leaks in your coolant lines, they'll check your indoor and outdoor units for damage. If the units are fine, a contractor may proceed with the repairs. A contractor may also cover the lines with new insulation and add new coolant to the system. Afterward, an air conditioning specialist will run your cooling system to ensure that it works properly. If a contractor notices something else wrong with the system or lines, they'll take action to fix them.

If you keep plants and other debris away from your coolant lines, you may be able to protect them from damage. Also, try to keep your lines slack instead of pulled tight. Refrigerant lines can pull away from the outdoor unit if they become too tight. If you can do so, place a border or small fence around your outdoor unit. Small children and pets may tug on the coolant lines or accidentally damage them. 

You can obtain the repairs you need for your coolant lines by contacting an air conditioning service contractor near you today.
