air conditioner

It is every owner’s worst nightmare.

The temperature rises and the air conditioner does not blow cold air.

Unless you understand the problem and can’t fix it quickly, things quickly get tricky and uncomfortable.

You know to look at the Top Air Conditioner Repair in Aliso Viejo before you turn it on, but don’t take the time to feel the pain anymore. Let’s see what you can do to bring back the cold.

1. Is the thermostat correctly set?

In general, the thermostat is the problem behind the uncooperative air conditioner.

If the thermostat sets a higher threshold, it may not turn on. For example, at 24 ° C, the air conditioner is set to 28 ° C.

At this point, an investigation is necessary. First: Have you checked that the stop switch (located in the stop box) is on? Have you checked the circuit breaker to make sure there is no trip?

Once this is determined, you will need to reset the thermostat and set the temperature a few times lower than at home.

For example, if the temperature in your house is 25 ° C, set it to 20 ° C. This way you will notice the change.

It takes a few minutes to smell the fresh air, so don’t panic if you don’t notice it right away.

After waiting, place your hand on the vent and see if you can smell the fresh air. Only a simple reset is required.

If you still don’t feel the cold air, there is a problem with the internal wiring, which may cause it to malfunction. In this case, consult a professional for the next step.

2. Has the furnace filter been replaced?

You might think your filter won’t blow cold air into your air conditioner, but it does.

If the air filter is not inspected and replaced regularly, it can become seriously clogged.

A clogged filter limits the flow of air into your home. This means that you will not only realize that you are lacking cold, but that you will also feel the dust and the general heat.

It is recommended to check and clean the air filter every 30 days and replace it if necessary.

3. Is the condenser dirty?

The outer part of the air conditioner is called the condenser. If dust and debris get into it, it will interfere with the process.

Your air conditioner has to work harder to suck in air and cool it. This is very similar to the problem that occurs when the filter is clogged. Fortunately, cleaning the condenser is something you can do yourself, but be careful not to bend or destroy anything.

We recommend that you use soap and water to gently wipe off the stain. Low-pressure hoses can also be used.

Purchase a weatherproof cover when the air conditioner is not in use to minimize future dust and debris. You should also weed and cut the area around the condenser so that branches and other plants do not stick out.

4. Are there any mechanical problems?

Over time, air conditioners, like most, experience normal wear and tear. This means that mechanical problems can arise at some point in the life cycle.

5. Have you performed annual maintenance?

Many homeowners think they don’t need annual maintenance. These homeowners experience sudden blackouts, high maintenance costs, and no one on the hottest days of the year. In GTA, this happens almost every day from mid-June to the end of September.

6. Is your air conditioner the right size?

Air conditioners that are too large or too small will wear out the air conditioner and cause a series of problems. It does not include the cold.

Unfortunately, this problem will continue to exist unless the air conditioner is replaced. If this is your choice, we can help you get the right air conditioner first.

How to troubleshoot a hot air conditioner

Thermostat

It sounds obvious, but the first thing to check is the thermostat. If the air conditioner blows hot air, the thermostat may inadvertently be set to “heating”. In this case, you can easily fix it yourself. Turn the thermostat back to “cold” and see if the Air Conditioner starts blowing cold again.

You should also check that the battery is working properly and that the temperature is not too high. The “auto” function only uses the fan when the air is heated or cooled.

The “on” function means that the fan circulates the air 24 hours a day, 7 days a week, even when the air conditioner and heater are turned off in contact. In most cases, we recommend that you use the “Auto” function and switch it to “On” only when necessary.

Solution: Check the thermostat and make sure it is set to “Cool” and is at the correct temperature. If you need a new battery, replace it. We recommend that you set the thermostat to around 78 degrees Fahrenheit during the cool season and 7-10 degrees higher when you are away from home. By reaching eight hours of frustration, you can save 10% of your annual heating and cooling costs.

Circuit Breaker

After checking the battery and thermostat settings, check the electrical panel to make sure the HVAC system is receiving power. HVAC devices require large amounts of energy to operate. If the power demand is too high, the circuit breaker can automatically cut off the power to ensure safety measures.

Solution: Locate the electrical panel and find a tripped circuit breaker or fuse. To turn the device back on, turn off the circuit breaker completely (opposite to all other circuit breakers) then switch it to the “position.

If the fuse blows, it must be replaced. This is also a great opportunity to mark all circuits for reference when the next one is overloaded.

Evaporator coil and air filter

The air filter is not related to temperature, but if the air filter is dirty, the evaporator coil can get dirty. If the evaporator coil is clogged with dirt or debris, it may not be able to circulate enough air for normal cooling operation.

A dirty air filter can accumulate debris and freeze the evaporator. “Freezing” may seem like a cold equivalent, but in reality, frozen ceramic can block the flow of cold air and drain heat from a running engine.

The replacement of the air filter should be done by the homeowner every 30 to 60 days depending on the climate, the type of filter, and the house.

We recommend that you set up a monthly reminder to check the condition of the air filter at the start of each month. If very little light passes when the filter is placed under the light, it should be replaced with a new filter.

Solution: If the evaporator coil is frozen, turn off the machine and replace the air filter. Wait for the device to unlock, then turn it back on. Technician solving problems. You may have a refrigerant leak or a compressor problem – you need professional help.

Condenser coil (outdoor unit)

After checking the thermostat, breaker box, air filter, and room go out and check the outdoor unit. The same goes for outdoor evaporators, where indoor evaporators require free air circulation. It is recommended to always maintain a clearance of at least 2 feet around the outdoor condenser.

Solution: If the outdoor unit is blocked, turn off the unit at the source. Then put on your gloves and take out the large items and wash off small debris with a garden hose. Learn how to clean your outdoor condenser step by step.

Remember to organize adjustments and cleaning at the start of each cooling season.

Make sure your HVAC company uses a thorough cleaning of indoor and outdoor coils as part of your regular adjustments. In addition to professional cleaning, we recommend that you regularly check the outdoor unit and clean it yourself if necessary.
