Generally, when we see that the air conditioning does not cool we tend to think that the problem lies in the lack of gas, we mistakenly think that the gas in an air conditioning must be changed, replaced or recharged from time to time.

However, there are times when this thought is quite incorrect since if the air conditioning installation is well done and no pipes have been broken by friction, vibrations, etc., the gas should not be lost and could remain inside the machine. and installation for years.

For these cases, it is important to observe in general each of the possible factors that make our air conditioning unit not cool and discard one by one. Guisan brings you a simplified guide of possible reasons why this happens:

Gas leak

This is one of the most common possibilities of why the window air conditioner does not cool. Although it is equally valid for split or duct air conditioners, the gas leak can be or can be found in 3 parts of our air conditioning, in the refrigeration installation (copper pipes and connections/welds), in the outdoor unit or in the unit interior, the first being the most common for units that have been installed for a short time and the last two for units that have been installed for a longer time.

Dirty filters

Many people forget that keeping some filters clean is essential not only for the correct operation of the unit but also to reduce consumption, not to force the operation of the machine and maintain a cleaner environment since these are in charge of filter the air in our home.

Dirty indoor fan

Another problem although much less common is the accumulation of dirt in the fan (impeller) of the indoor unit, this problem usually occurs with much more virulence in the only cold units and less in the heat pump units, it is also more common in Smoking environments, factories or premises where sprays such as lacquers or paints are used since they help fix dirt, this cleaning is a very easy way to fix an air conditioning that does not cool if you forget to do it, since It may be that your problem if your air gets too cold.

Dirty interior or exterior exchanger

If we have talked about the importance of keeping clean filters in our air conditioning for its correct operation, the same or more important thing is to keep the exchangers clean, since that is how its name indicates where the exchange of cold or heat occurs and is a fundamental part of our air conditioning equipment, all window, splits or duct air conditioning units have two heat exchangers, one inside (internal heat exchanger) and the other outdoors (external heat exchanger) although in window air conditioning units it may not seem that the two are together in the same unit.

Starting capacitor

The starting capacitor is in charge of giving the necessary current to the motors of our air conditioning equipment so that they can start, generally, these equipment have 3 motors, the motor of the external fan, the motor of the internal fan, and the compressor and of 2 or 3 capacitors.

Other possible factors

With the proliferation of inverter air conditioners, many of the equipment breakdowns are related to electronic boards, making it rather difficult for someone who does not have the necessary training to determine and repair the fault, so it is always advisable to contact the official technical service. for you to find out and solve the problem since the current units in their electronics part have become quite complex.

We rarely pay attention to our air conditioning systems, until a problem arises. Imagine that your air conditioner stops working just in the summer when HVAC technicians are busier. You would probably spend days bearing the intense and suffocating heat at home.

Of course, repairs are less expensive than installing a new heating and air conditioning system, but the cost of an old heating and air conditioning system can continue with periodic repairs and inefficient operation.

So when should you finally make the call to replace your heating and air conditioning system? How old is your heating and AC system? Hopefully, you may have information on when all the components of your heating and air conditioning system were installed.

– Age of product

If your unit is already 10-14 years old, it is common for these systems to start to fail in terms of efficiency. We know that technology is advancing very fast and now there are more modern types of equipment, and it is likely that the repair of your air conditioning will be more expensive due to the difficulty in obtaining certain parts, or that even the parts are discontinued, therefore it will be better to consider buying a new one.

– Refrigerant

A refrigerant gas leak is one of the most common problems when repairing air conditioning. The solution is not only to supply gas to the appliance but also to repair those faults that trigger the problem. A licensed technician will be able to seal leaks, check proper operation, and then supply gas to the equipment. However, sometimes it is cheaper to buy a new air conditioner than to buy new parts, and in that case, it is convenient to take into account that the new air conditioners use a more eco-friendly type of refrigerant so it would be a “win-win” situation.

– Power bill

High bills could be the result of faulty machinery. An inefficient air conditioning system operates more frequently while using more electricity without adequately cooling the home. Many utility companies provide comparative tables of how their bills have changed month to month and year to year. Often, they also provide an average temperature for each day of the month, data that can help you identify if changes to your bill are related to outside temperature or something else. Newer refrigeration systems will also tend to be more energy-efficient than previous models. Investing in a system with an energy-saving system could bring you dividends in the future.

But if it keeps failing…

Whether your system has reached the end of its useful life or not, having several serious repairs consecutively indicates that the system has reached the end of its functionality. Remember that systems last only as long as they are well maintained, and some simply won’t last as long as others.

People whose air conditioners are located near windows or in the yard can benefit from the new and quieter air conditioners being built today. If you have already fixed a problem but it keeps failing, it is better to reduce your losses and replace your unit.

It is important to be aware of each of these factors and keep their environments and spaces fit and prepared, not only for the seasons that require their use but also for those in which it is essential to have reliable and safe equipment.

You cannot stop a tropical storm or hurricane, but you can take steps to protect yourself and your family. If you live in a risk area, the Centers for Disease Control and Prevention (CDC) advises you to be prepared for the hurricane season. The season in the Atlantic is from June 1 to November 30 of each year.

It is always important to be prepared for a hurricane. Your planning this year could be different due to the need to protect yourself and others from COVID-19. Public health and emergency response professionals have recommendations to help you prepare, evacuate, and shelter safely in the event of severe storms, while protecting and protecting others from COVID-19.

Storms don’t just bring rain and wind. They also cause power outages that can leave you without the comfort of your AC system and other appliances for hours or days. Make sure you take special care with your HVAC, so it can stay cool between storms.

At Guisan Air Conditioning we share 6 steps you can take before, during, and after a storm to minimize damage to your AC system and get it running faster when you turn it on again:

Pre-Cooling Your Home:

If you think your power can be turned off during a storm, go ahead and cool your house ahead of time so you can stay comfortable until power is restored. Place the thermostat in a cooler position than normal, close curtains and blinds, and keep doors and windows closed to keep cold air inside.

Disconnect electricity from your air conditioner:

Electrical surges from lightning during a storm can damage your air conditioning unit. There is also a possibility that dirt will stick to your outdoor unit and start the engine. Stay safe by turning off the power to your AC system. We recommend that you turn off the power on your thermostat and circuit breaker.

Cover your outdoor air conditioning unit:

This step is only really necessary if you are expecting a hurricane and strong winds. After you have turned off your air conditioner, cover it with a tarp or plywood to protect it from flying debris. Strong winds can knock down branches and trees that could damage your unit if they fall on it. Be sure to remove the cover as soon as possible. Keeping your unit covered for a long time can trap moisture that leads to mold.

Secure the unit:

If you have an elevated air conditioning on a second floor, be sure to secure your outdoor condenser unit with hurricane straps to keep it in place during strong gusts of wind. If your area is prone to flooding, we suggest you contact your AC contractor to raise your unit for better protection.

Check for damage before resetting your air:

This is one of the most important steps. Don’t forget to assess storm damage before turning the system back on. Flooding or flying debris could have damaged your unit and turning it on may worsen the problem. Also, storm winds cause disconnections inside your air conditioning unit, which could lead to leakage of toxic refrigerants. Turn on your air conditioner as soon as it seems safe. This will prevent mold and mildew from installing.

Contact an HVAC professional:

If you have problems or need repairs, it is safest to call an HVAC expert near you to inspect your AC system for damage after the storm. That will give you professional peace of mind that you are operating safely and properly.
