Air Conditioning FAQs, answered by experts

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
