Preventing damage to the AC unit
An AC unit is a substantial investment, and it is important to take steps to prevent damage to it. Here are some ways to prevent damage to your AC unit:
Firstly, it is important to be vigilant about regular maintenance. Most common problems with AC units are preventable with routine upkeep. This includes replacing air filters, which can become clogged and cause airflow problems. Clogged air filters can also cause higher energy bills. Similarly, it is important to clean the ductwork of your AC unit. Leaks or gaps in the ductwork can cause cooled air to escape into your walls, making your AC unit work harder and increasing your energy costs. Leaking ducts can be caused by rodents or poor installation, so it is important to have a professional inspect and repair any issues.
Another important aspect of AC maintenance is keeping the outdoor unit clear of debris. Leaves, dirt, and trash can clog the condenser and outdoor unit, rendering it ineffective at expelling heat. Cut and clear any plants, trees, or shrubbery near the AC unit to prevent debris from accumulating. This is especially important after storms, which can cause severe damage to AC units. Strong winds can push debris into the outdoor unit, causing blockages and putting extra strain on the system. After a storm, check for any signs of damage, such as disconnected wiring, a displaced condenser unit, a missing cover, or damaged coils. Have a professional inspect the AC unit to determine the extent of the damage and make any necessary repairs.
In addition to regular maintenance and keeping the unit clear of debris, there are other measures you can take to protect your AC unit. For example, installing a surge protector can help absorb excess electricity in the event of a power surge, which can damage the electrical components of your AC unit. You can also use tie-down straps to secure the condenser unit and prevent wind damage.
Finally, it is important to address any issues with the AC drain pan promptly. The drain pan collects moisture from the air before it is funnelled away from your home. If the drain pan becomes cracked, rusted, or corroded, it can lead to water leaks and potential mould growth. Inspect the pan regularly for damage, especially along the edges and corners, and replace it if necessary.
By following these preventative measures, you can help ensure that your AC unit operates efficiently and lasts for many years.

How to identify if the AC drain pan needs to be replaced
The AC drain pan is located in the indoor unit, underneath the evaporator coils, usually on the same side as the air intake. There are usually two pans: a fixed drain pan under the coils and an overflow pan below that. The pans collect condensation formed when warm air passes over the chilled coils. The collected water is then drained away to prevent pooling inside the unit and causing damage.
Several factors can lead to premature AC drain pan replacement. Wear and tear, exposure to moisture, and a lack of maintenance can damage the pan. Cracks, rust, or corrosion on the AC drip pan are clear signs it needs to be replaced. Inspect the pan closely for damage, especially along the edges and corners where it’s most likely to occur. If you notice that the drain pan is leaking, use epoxy glue to plug small cracks. However, if the leak is large, it is better to replace the pan. Pooling water around your indoor unit likely indicates a compromised drain pan or a drain line clog. If you notice a damp or musty smell coming from your AC, it could signal mould or mildew growth due to a broken drip pan.
To inspect your AC drain pan, turn off the power to the air conditioner unit by flipping the switch near the air handler or furnace. Open the access panel or cover to access the pan. Use a flashlight to inspect the pan and the overflow pan. Note any cracks, dents, holes, rust, and mould or algae build-up. Check the opening to the condensate drain line and the drain pipe for any obvious backups or debris. Visually inspect the entire drain line (indoors and out) for any cracks or damage and ensure it is properly draining outdoors.
If you are uncomfortable performing these tasks on your own, contact a professional HVAC technician.
