how to fix air conditioner not cooling

 

Today, air conditioners play a vital role in human life. Air conditioners can be used in the summer as coolers and in cold months as a heating system. These cooling or heating equipment today are the most used in our lives and, for example, may serve us 24 hours a day in the summer. This type of equipment is used in many places. In public transport such as city trains, buses, taxis or in public places like hospitals, schools, libraries, and Etc.

Perhaps at the beginning of the invention of this kind of equipment, nobody thought that one day we should always be with us and be installed on any moving device. Perhaps at the beginning of the invention of this kind of equipment, nobody thought that one day should always be with us and be installed on any moving device. It’s so exciting that air conditioners are used in the heavens (on the plane).

The expansion of air conditioning over time has caused the need for repair or maintenance of these types of devices.

This improvement should be accompanied by the training of technicians.  Because the path to the progress of these equipment was quickly over. For this reason, in the free technical schools, people were trained to repair these equipment. This led to a lot of cost savings and, for example, if a piece was damaged, it would not be necessary to change the entire equipment. It is also replaced by a technician .

An air conditioner repair technician can fix the wiring, reset the circuit breaker, and make sure no vegetation is blocking airflow to the outdoor unit. The fan belt is worn out. … If it snaps before an AC repair technician replaces it, the repair could end up being far more expensive. There is a refrigerant leak.

 

The perfect season for air conditioning service

The perfect season for air conditioning service

Heating and Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring. It is better to repeat this course every year  .

If you forget one year and do not service your air conditioner, you should do it as soon as possible. AC professionals often say that even if you do not suspect that your air conditioning unit has problems, you need to have it serviced and inspected at least once every year. As this will ensure that it operates at maximum efficiency, no loss.

What happens in ac service ?

An Air condition collects a huge amount of dust and debris when it operates. During an air conditioning repair service call, all the dirt and dust are removed and cleaned to prevent problems like ice formation in the Ac or AC not cooling.

If not done …

Ever wondered how is AC service done and what makes it so important every year to get your AC serviced? Read on and you will understand! An air conditioner collects dust and debris during operation which prevents it from cooling properly. Whether you have a window AC or split AC, it is very important to service your AC to ensure a trouble-free performance. Apart from efficiency and performance, AC service also helps you ensure there are no problems inside your AC and that every part of the AC is functioning in an appropriate manner. Missing AC services can cause several problems inside an AC like water leakage from AC, AC not cooling, AC making noise etc. These problems can be prevented by regular AC service and maintenance.

An air filter collects humongous amount of dust and dirt during operations. Dirty air filters in AC cause problems like ice formation in AC, AC not cooling etc. During AC service, the technician washes and cleans air filter. The condenser fins are also rinsed and cleaned for any molds and dust build up during AC service.

 

What is needed in air conditioning (HVAC) services to check?

What is needed in air conditioning (HVAC) services to check?

If your HVAC system isn’t running as well, as usual, you might be tempted to contact a professional technician immediately. However, in some cases, checking a few simple things first can save you a lot of time and money.

  1. CHECK THE AIR FILTER

Reduced airflow hinders an HVAC unit’s ability to perform properly. As a result, energy efficiency goes down, and your utility bills go up. One of the most common causes of reduced air flow is a dirty filter. Start there when HVAC problems occur, and be sure to replace the filter frequently to minimize future issues.

  1. CHECK THE THERMOSTAT

Incorrect thermostat settings are a common cause of unnecessary HVAC maintenance calls. Even if you’re confident that everything is set correctly, be sure to check the thermostat to ensure nothing was accidentally changed. It’s surprisingly easy to turn the HVAC unit off altogether from the thermostat. Many people have also switched their unit to air conditioning when they wanted heat and vice versa.

  1. CHECK FOR ICE AND OTHER OBSTRUCTIONS

If the unit is icy, you need to turn it off. Next, look for any obstructions blocking the supply vents and filter. Obstructions need to be cleared away, and this may be enough to restore your HVAC system to full functionality. If there aren’t any obstructions or things, don’t return to normal, be sure to contact a technician for assistance.

 

  1. CHECK FOR POWER SUPPLY ISSUES

There might be a switch located near the HVAC unit that looks like a light switch. This can easily get flipped off, plunging your house into what seems like a heating or cooling nightmare. Simply flipping the switch back on should make everything work normally again.

 

If there’s not a switch or it hasn’t been flipped, check the circuit breaker. Many HVAC calls occur because of a blown fuse. Outdoor units sometimes have a separate fuse for the disconnect switch, so always check that as well.

CHECK THE PANEL SWITCH

  1. CHECK FOR FLASH CODES OR THE PILOT LIGHT

Older gas furnaces stop working when the pilot light goes out. Therefore, anyone who has one of these units should always ensure the pilot light is still lit. Newer electric units don’t have this requirement, but they do usually have flash codes that can help you determine what’s wrong.

 

Keep in mind that seeing a flash code isn’t an automatic indicator that there is a problem. Check the furnace panel for an explanation of each code. If the flash code is indicative of an operational issue, be sure to contact a professional technician.

 

  1. CHECK THE PANEL SWITCH

Is there a loose panel on your unit’s air handler? The associated panel switch may have cut the power as a safety measure. These panel switches are intended to flip their switch whenever a panel is removed or is not attached properly. In this instance, you will probably be able to repair the unit yourself by simply reattaching or tightening the panel.

 

There are several other items to keep an eye on as well. For example, a gas furnace may stop running because the utility company has cut off gas service. This doesn’t mean you didn’t pay your bill. However, it could mean there’s a gas leak or someone in the billing department made a mistake. If the gas valve is locked or there’s a red tag on the meter, contact the gas company for more details.

 

If none of these simple fixes gets your unit running again, you will need to schedule a professional HVAC maintenance call. Learn more about common HVAC issues or schedule routine HVAC maintenance by calling Bentley’s Air Conditioning today!

5 Problems of the air conditioner and its solution

5 Problems of the air conditioner and its solution

According to experts, “home appliance repairs”, the air conditioner is actually a respiratory lung of a building, which is used to release fresh air at a suitable temperature to the building during the warm and cold seasons. Of course, in most buildings, heating is provides with a heater, or a radiator and a fireplace, and air conditioning systems are only used in the warm season.

If your air conditioning system does not cool or does not work at all, read this article for five common reasons for the failure of the air conditioning system from the viewpoint of home appliance repair experts. If your air conditioning system does not cool or doesn’t  work at all, read this article for five common reasons for the failure of the air conditioning system from the viewpoint of home appliance repair experts.

When your air conditioner is switched on at the beginning of the season, does your cooling system boom? Do you hear a groan and a blow you’ve never heard of before?

Does the cooling system not cool? Home Appliance Repair Experts say your cooling system may have one of the following five common problems. According to the tips provided, check your air conditioner and repair the relevant appliance.

The first problem: the air conditioner does not work at all

Home appliance repair experts say it’s likely that you’ll need to track thermostats first. If the batteries were healthy, the next recommendation of the home appliance repair technician is to test the circuit breaker. If that part is healthy, make sure the machine is set to cool. If there is no problem with them, it’s time to contact a home maintenance technician.

The second problem: lack of uniform cooling

If one of your rooms is freezing and the other is hot like a sauna, what is the problem with home appliance repair technicians? Check out a few things. Are the air channels impeccable? How to insulate the rooms? Channel leakage or building insulation is one of the major causes of the uneven air conditioning system.

Third problem: it does not cool at all

Have you changed the air filter in recent months? Otherwise, be sure to change it. If the unit still does not cool, there may be a problem with the thermostat. If your thermostat is completely healthy, it’s the next idea of the home appliance repair technician. What is the external unit? Are they surrounded by plants grown? Does it dump something? Contact the appliance repair technician if you have not experienced a clear breakdown.

The Fourth Problem: Dripping water

Home appliances repair experts relate the water leakage to a blocked filter, a cracked water drain line or an insulation that goes away from cooling pipes. You can check these items yourself. If you can not find the source of the problem, refer to the home appliance repair specialist.

 

The Fifth problem: Coils are frozen

The cause of freezing coils is usually due to lack of refrigerant gas or blockage of air flow. To check for blocking the lack of air flow to the advice of home appliance repair technicians, first check the air filter to make sure it does not clog. If the filter is dirty, clean it or replace it. Then place your hands on the air vent valve to make sure you have good outlet air flow. If the air filter is clean but still does not have an outlet airflow, home appliance repair technicians say you must check the channel path that is blocked and unplugged.

 

Sometimes the common problems of the air conditioner system are easy to solve and maybe with some care you can fix it yourself.

A few tips for maintaining air conditioning systems

An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

 

What should a technician do?

What should a technician do?

When your air conditioner needs more than regular maintenance, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.

The technician should:

  • Check for correct amount of refrigerant
  • Test for refrigerant leaks using a leak detector
  • Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere
  • Check for and seal duct leakage in central systems
  • Measure airflow through the evaporator coil
  • Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
  • Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
  • Oil motors and check belts for tightness and wear
  • Check the accuracy of the thermostat.

How much does it cost to hire an annual air conditioner maintenance service?

Maintaining your air conditioner (HVAC) unit will ensure that it’s ready to properly cool your home all throughout the summer. Keeping your unit in good condition is also important for your wallet: lack of maintenance shortens a unit’s lifespan by 10-15 years, meaning you’ll need to buy a new one sooner. Lack of maintenance also results in a 5% efficiency loss, which results in higher energy bills.

 

For this discussion, we will consider the costs of maintaining an air conditioning unit annually. A flat fee for a one-time maintenance visit costs $ – $ and an annual maintenance contract will cost $.

Timing

You should have your air conditioning maintenance done at least once a year, in the spring. Doing it in the spring will allow your technician to repair any damage the unit might have acquired during the winter, and make it ready just in time for the arrival of warmer temperatures. However, it’s best to do maintenance twice a year: in the spring and fall. Sticking to this bi-annual schedule will keep your unit running optimally.

Maintenance contracts

Many HVAC maintenance companies offer annual servicing contracts for preventative maintenance. Such contracts cost anywhere from $100-$150 per year, and cover annual visits in which standard maintenance tasks are performed. Some companies will allow you to make monthly payments for your maintenance contract, and will provide you with discounts around 15% if you hire them when you need your unit repaired.

 

Getting a contract will usually give you more warranty coverage than if you just paid for a single maintenance visit: if anything is wrong with your unit between maintenance visits, your HVAC technician will come and address the issue.

The average life span of central air-conditioning system is 12- to 15- years if it is properly installed and maintained. Heat pumps have about the same life-span — about 14 years — when recommended maintenance is followed. Newer units manufactured in recent years are expected to last even longer.

in the end…

Of all the above, it can be concluded that maintenance of air conditioning systems is easy and, if it is difficult, can be solved by a technician. Maintenance of the system by ourselves only requires a good memory .
