- Call Blue Sea Plumbing for repairs and assistance.
Your AC is on but the room still feels hot. You check the vents and the air is not cold. This happens to many people each summer. It can make you feel stuck and tired.
In Canada, almost 68% of homes use air conditioning systems to keep cool in summer. But when the unit stops working right it can raise your bills and lower your comfort.
The good news is that most AC problems don’t need full replacement. A simple part might need care. A minor adjustment might resolve the issue. You just need to know where to look first.
Blue Sea Plumbing helps people like you deal with this. If your AC fan is not turning or your AC unit is leaking, this blog will help you know what to do next.
Dirty Air Filter
A dirty air filter can block airflow and put stress on your AC. When air does not pass through the filter well your system cannot cool rooms the right way.
These signs often mean the filter is clogged.
- You may notice weak airflow.
- You may also see more dust around vents.
- Sometimes, the AC may run longer but not cool the space.
To check it turn off your AC and remove the front panel. Take out the filter and hold it up to the light. If you cannot see through it the filter needs to be replaced. You can purchase one from a hardware store or seek air conditioning assistance from Blue Sea Plumbing. We know how to keep your AC system in shape.
Clean filters help your unit run better and save energy too. If the filter stays blocked for too long, other parts of your AC can get damaged. That may cost more in repairs.
AC Fan Not Working
Your AC fan plays a big role because it pushes cold air through your house. When the fan does not spin your rooms stay warm which makes the air heavy.
You can walk near the indoor unit and listen. If you hear the unit turn on but feel no air, the fan may not work. Sometimes, dust or worn-out parts can stop it.
Try this. Turn off the power. Wait for a few minutes. Then turn it back on. This can reset the system. If the fan still does not move it is best to call a pro.
The fan motor is not easy to fix at home. You may hurt other parts if you try on your own. Blue Sea Plumbing has techs who check this fast. We can tell you what went wrong and fix it the right way.
Low Refrigerant
Refrigerant makes your air cold. It moves through your AC in a closed loop. When levels go down, your system blows warm air instead.
You may see ice on the coil. You may hear a hissing noise. You may notice the unit runs too long but does not cool well. These are signs the refrigerant is low.
This is not a part you can fill on your own. Only licensed techs can do that. They have tools to measure pressure and check for leaks.
If you think your system has low refrigerant, do not wait. It can damage the compressor and result in significant repair costs. A fast check can save you stress and money.
Leaking AC Unit
If you see water near the indoor unit, that means trouble. Your AC should not leak. This shows a problem inside.
One common cause is a blocked drain line. Dirt or mold can fill the pipe. Water then builds up and spills out. Sometimes the drain pan cracks and leads to a leak.
A leak can damage your floor and cause mold. You may notice a musty smell and feel damp air near the unit.
To spot a leak, check the floor near your AC. Look under the indoor unit. Feel if it is wet. If yes, turn off the system. Use a dry cloth to clean the floor. Then call a licensed tech.
Blue Sea Plumbing can fix this fast. Our team clears blocked lines and replace cracked parts.
Frozen Evaporator Coils
If the coil inside the indoor unit is clogged with ice, it cannot cool your home. This coil must stay clean and dry because ice stops it from working well.
You may see frost near the vents and weak airflow. Sometimes, the air feels warm. These are signs the coil has frozen. This happens when there is insufficient air due to dirty filters. A fan issue or low refrigerant can also lead to this.
To help, turn off the AC and let the ice melt. Do not poke the coil, let it dry fully. When it melts, call a pro.
Quick Fixes You Can Try First
Before you call a tech, try a few safe checks at home. These help spot small issues fast.
- Check the thermostat: Make sure it is set to cool. If the screen is blank, the batteries may be dead. Try fresh ones.
- Look at the air filter: A dirty filter blocks air. Pull it out. If it looks dark or dusty, replace it.
- Inspect the vents: Walk around your home and put your hand near each vent. If no air comes out, the duct may be blocked. Move any objects away from the vent.
- See the outdoor unit: Step outside and look at the box. Leaves or trash may sit near it. Clear the area so air can flow.
- Flip the breaker switch: Find your home’s breaker box. Look for the AC switch. Flip it off and back on. This may reset the unit.
- Listen for odd sounds: If you hear loud bangs or buzzing, turn the system off. This may mean a bigger fault.
- Smell the air: If you smell gas or smoke step outside and call for help fast. Do not stay indoors.
These steps are safe. Do not open the unit to fix wires. For expert help, call Blue Sea Plumbing. Our team handles full checks. We fix the root cause. We make sure your AC runs cold and smooth again.
