Changing the filter when it becomes clogged is arguably the most important HVAC maintenance task. This maintains adequate airflow so the AC doesn’t overheat. It also helps cooled air circulate efficiently to keep your utility bills down.

Standard air filters should be checked once a month and replaced after no more than three months. High-efficiency filters may last up to a year, and some filters can be washed and reused.

The primary function of an air conditioner is to remove sticky water from the air and put it into a drain. When sized correctly, the cooling affect is often secondary or incidental. Many times, the drain can become obstructed from dirt, especially if the air filtration system is poor.

The other reason an ac leaking 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. When this happens, water collects & turns to ice and grows larger than the drain system, then defrosts. This water can infiltrate dark places and grow mildew, or even affect electronic components, damaging your hvac system. Inspect carefully with the power off and good a flashlight to see where the water is starting from. Many times, a hand from a hvac pro can save you lots of frustration.

It’s probably time to consider replacing your air conditioner if you are investing a lot of money into repairing it. It’s best to replace your air conditioner before the extreme temperatures arrive to ensure continued comfort & safety.

R-22, otherwise known as freon is an older type of refrigerant while R-410A is used on newer air conditioners & rooftop units. In January 2020 R-22 was phased out & is no longer being manufactured.
