One of the keys to long-lasting HVAC systems is to conduct air conditioners troubleshooting whenever you notice a problem with cooling performance. Many common AC problems are actually simple to fix, especially if they are caught early. Here are some of the AC problems you may encounter, according to Consumer Reports, and how to troubleshoot them.
The number one most common problem with central air conditioning is clogged air filter issues. A dirty air filter prevents air from flowing properly through the ventilation system, which will limit the amount of cool air distributed through the home. Air filters need to be replaced periodically from three to twelve months, so keep a schedule when to buy new filters.
The next important item on your checklist should be to check the thermostat to make sure it's in the proper setting and not exposed to direct sunlight. It's actually possible for it to display an inaccurate temperature if the sun is shining on the unit.
Then check the registers to see if they need vacuum treatment to remove dust or dirt that may be restricting airflow. At this point, you can also determine if any furniture or other physical items are blocking the airflow. When there is poor airflow circulating throughout your home it's time for a broader inspection.
When your air conditioner is running but not lowering the temperature there's a chance it's because warm air from the outside world is entering your home. That's why you need to periodically check your windows and doors to see if there are any leaks, which can be easily fixed with sealant.
When you hear a clicking sound but cooling isn't working it could mean the AC needs more refrigerant. The clicking sound indicates the thermostat is working. A faulty compressor may also be the culprit. Compare the temperature of air coming into the home with the temperature of the air leaving the home to make sure cool air isn't being replaced by warm air.
One way to understand a window air conditioner better is to study a diagram and analyze how the different components work together. The main cooling element is the condenser fan, which connects with a blower, a compressor, and condenser coils. In between the outer controls and the inner mechanisms are the air filter, which is set within an air inlet grill and air outlet grille.
Larger homes often use HVAC split systems, in which the condenser and compressor operate inside an outdoor cabinet. It combines with an indoor cabinet and an air handler, connected with a copper tube, which moves cold air into the home. A split system adds energy efficiency to a home and equipment placement can be customized. Split systems also usually don't require as much maintenance as HVAC-packed units.
When the AC won't turn on it can be for several different reasons. Some of the most common reasons include refrigerant leaks, fan belt issues, and too much condensation from debris accumulation. Faulty wiring or poor installation can cause numerous issues that often lead to reinstallation.
It's wise to work with experienced professionals who guarantee proper installation, whereas the friendly but unlicensed neighborhood handyman might not have the right tools, skills, or guarantees to ensure proper installation. A novice might not understand split systems or have the right tools.
Since a split system has more moving parts compared with a packed unit, you can expect certain parts to eventually wear out and require replacement. Many homes store HVAC components of split systems in basements where sufficient space is available. It's easy for some people to forget about their basements, which can lead to neglect of your HVAC equipment. By getting it inspected once a year you'll remember its importance in terms of energy efficiency and long-term savings.
One of the complexities of HVAC systems is different brands have different troubleshooting processes. Most consumers are not experts at HVAC or the brands associated with the industry. If you ever smell burning regardless of brand, shut the breaker off immediately. Here are some important troubleshooting tips to know about some of the major brands.
