The life expectancy of an air conditioner varies from climate to climate; the average age at replacement is 13 years. Your personal threshold for discomfort in sticky weather may cause you to replace your system every 10 years, or even when a major repair is needed. Medical conditions, empty or uncomfortable areas of your home, and a few other factors cause many homeowners to add a supplemental ductless heating and cooling system and see how many years they can get out of their central cooling system.
The primary function of an air conditioner is to remove moisture from the air and drain it away. When sized correctly, the cooling effect is often secondary. Many times, the drain can become obstructed by dirt, especially if the air filtration system is poor.
The other reason an AC leaks can be more serious—ice. When refrigerant levels are low and/or airflow is restricted, the AC coil by your furnace or air handler freezes. Water collects, turns to ice, expands beyond the drain system, then defrosts. This water can infiltrate dark areas and grow mildew, or even affect electronic components. Carefully inspect with the power off and a good flashlight. Often, a hand from an HVAC professional can save you a lot of frustration.
Servicing the AC every year is the best way to stay ahead of problems or major repairs. A malfunctioning system in extremely hot temperatures is not only uncomfortable but unsafe. An annual tune-up by a professional, licensed HVAC contractor ensures your system is clean and operating both efficiently and safely.
AC coils should be cleaned every year during the spring or summer months to prevent costly repairs. During an AC cleaning, a licensed HVAC technician will check the coil for cleanliness, leaks, and refrigerant levels. All gas and electrical components are inspected for safety and performance. Your technician will inspect and change your filters, but it is also important to regularly change your filter every month in between seasonal tune-ups.
It’s time to consider replacing your air conditioner if you are investing a lot of money into repairs. It’s best to replace it before extreme temperatures arrive to ensure continued comfort and safety.
If you are purchasing a new AC, request several estimates from licensed contractors. When comparing quotes, consider:
Avoid DIY work or hiring a handyman, as this will void the manufacturer warranty. Hiring a professional saves money and ensures comfort all summer long.
Most furniture manufacturers recommend professional cleaning every 12 to 24 months, depending on usage and environment.
