Mistakes in AC repair and maintenance can damage the system in addition to normal wear and tear. One error or misjudgment can lead to costly problems or an early system replacement. Therefore, a qualified professional must handle any air conditioning repair (aside from changing the air filter or simple cleaning). Not calling for help when necessary, mishandling the system, or improperly maintaining it can lead to substantial damage.
Avoiding these common mistakes can protect your AC system and household budget:
Changing the filter regularly is the golden rule of air conditioner maintenance. Replacing it every three months or more frequently can prevent costly AC repairs. Set reminders to check the filter. If it becomes clogged with dirt, your entire HVAC system works harder to achieve the desired air temperature, increasing utility costs and straining already hard-working components.
As every AC professional agrees, replacing the air filter is the easiest and most important way to care for your air conditioner. However, the filter must be the right type and size for your system. Its length and width must fit the space exactly; for some units, the thickness of the filter must meet exact specifications. Otherwise, it may decrease performance or cause permanent damage.
No matter who services your air conditioner, the underlying problem must be properly identified before it’s repaired. Experienced professionals have the tools to diagnose a wide range of issues. For example, leak detectors can identify damage to a coil, while voltage testers can help find a faulty electrical component. Attempting repairs without a proper diagnosis can result in overlooking the root cause of the problem. Or, the repair may ultimately be ineffective. In either case, there’s a high risk of additional damage.
Loud noises don’t just happen normally as your AC is running. You or anyone servicing the unit must take these seriously. Unusual noises are a telltale sign of a problem. Ignoring them can allow an issue to escalate until there’s major damage, such as a failed blower or a burnt-out compressor. Safety hazards such as a refrigerant leak or a short circuit are also possible.
Therefore, call a local HVAC contractor if you hear the following from your AC:
Working with an AC’s electrical components requires extensive knowledge and training. Not every AC repair technician is equipped to handle electrical issues. Attempting an electrical repair without expertise is highly dangerous. Aside from the potential for a shock, burn, or electrocution, it also risks causing extensive damage to your air conditioning system. For example, a mistake fixing faulty wiring or a capacitor can trigger a surge that shorts out major components. It can also lead to an electrical fire.
Touching a live electrical part without protection, not turning off the system, or installing an electrical component incorrectly is bad enough. However, a far too common issue is cutting an electrical wire. This may seem appropriate if something isn’t working; just cut a wire, splice it back together, or replace it.
But it’s not this simple. Your AC system has many wires and connections. Whether you cut one during repairs or by accident while trimming hedges or mowing your lawn, the results can be bad. The effects can range from reduced cooling capacity to your AC being unable to turn on. Hiring a professional is the best way to avoid wiring mistakes. They can also install and wrap wires to ensure they’re stable, protected, and unlikely to be accidentally cut.
Every part installed or replaced in your AC is specific to the make and model. If the wrong part is installed, it may be incompatible with the system. Your AC may not work at all, be damaged in the process, or wear out at an increased rate. Always follow the manufacturer’s guidelines for selecting parts and hire a professional familiar with your type of system. Some ACs may also require specific tools to complete certain repair tasks.
Some people cover their outdoor condenser unit to protect it and avoid repairs. However, this can have the opposite effect. Outdoor units are typically built to withstand extreme temperatures and inclement weather. Don’t cover the entire unit while it’s running. The covering can disrupt airflow, overworking the unit. Or, its materials may be sucked into the machine, so you may need a major AC repair before you know it.
Call a professional as soon as your AC:
Homeowners often wait too long once they notice these symptoms. But the longer you wait, the more damage can occur. Your safety may also be at risk. Therefore, call an HVAC technician as soon as possible to diagnose and resolve the issue before it gets worse.
An AC repair comes with many hazards. One reason to call a professional is that they know the risks and how to mitigate them. They wear protective gear such as gloves, goggles, and insulated shoes to protect themselves from harm. Other safety precautions include turning off the power while working on a system and following industry guidelines for handling, charging, and disposing of refrigerant.
Never attempt to fix your air conditioning system yourself. Other than changing filters and cleaning the outside of units, DIY repairs are far too risky. Aside from the safety hazards, there’s the chance of causing damage that requires expensive repairs. You’ll pay out-of-pocket for these if a DIY repair voids the warranty. Therefore, always call a licensed professional to diagnose and repair your AC System.
Another big AC repair mistake is neglecting to schedule regular maintenance. It can lead to reduced cooling performance, higher energy bills, and safety hazards. Basic professional maintenance tasks like cleaning coils, lubricating moving parts, tightening electrical connections, and measuring refrigerant levels can make a big difference. During annual maintenance, a technician can also make minor repairs to prevent larger problems that may shorten your air conditioner’s lifespan.
