Experts warn against four common mistakes that can damage or impair your central AC system, including DIY repairs, neglecting filter changes, setting temperatures too low, and skipping annual maintenance. Avoiding these can save money and extend your unit’s lifespan.
Homeowners should avoid four common mistakes that can damage or reduce the efficiency of their central AC units, according to industry experts. These errors, if unaddressed, can lead to costly repairs and decreased cooling performance when temperatures soar.
Experts emphasize that attempting DIY repairs on a central AC system is a significant mistake. Traci Fournier, vice president of operations at One Hour Heating & Air Conditioning, warns that ACs contain delicate components that require specialized knowledge and tools. Opening the unit or trying to fix refrigerant leaks without professional help can cause further damage and void warranties.
Another critical error is neglecting to change the air filter regularly. A clogged filter reduces airflow, forcing the system to work harder, which increases energy bills and accelerates wear on components. Learn more about home organization tips to improve efficiency. Fournier recommends checking filters monthly and replacing them based on their type and household conditions.
Setting the thermostat too low is also problematic. While it might seem intuitive to cool the home faster, operating below the standard 75 degrees Fahrenheit can strain the system, potentially causing it to freeze or malfunction. Using programmable thermostats can help maintain optimal settings without overtaxing the unit.
Lastly, skipping annual maintenance can lead to system malfunctions. Routine professional checkups involve cleaning coils, inspecting controls, and removing debris, which helps prevent unexpected breakdowns and prolongs the system’s lifespan. Avoid clutter in your home to keep your system running smoothly.
Why Proper AC Care Prevents Costly Repairs and Discomfort
Following expert advice on what not to do with your central AC can save homeowners significant money by avoiding repairs and improving energy efficiency. Proper maintenance and usage ensure the system operates reliably during peak summer heat, reducing discomfort and preventing breakdowns when you need cooling most.
