    Why Doesn’t My HVAC System Work?

    Why Is My House So Cold?

    I think the above question will spring to mind immediately when you find out that your air conditioner is malfunctioning. Air conditioning repair can be difficult to deal with. You need the help of an expert to resolve the problem, or another option would be to learn how to do it yourself. Here are the steps you should take to avoid the humid, uncomfortable weather during the summer:

    • Your air conditioner could be malfunctioning for several reasons. It might be that the compressor or motor has broken or that the thermostat has failed. Also, your refrigerant might be running low, or a filthy evaporator could be causing issues.
    • In these situations, repairing your air conditioner by giving it a simple clean could get it working again. However, a part might need replacing, or you might be best advised to replace the unit – rather than attempt any repair work.
    • Several things could cause your evaporator coils to freeze. If your air conditioner runs round the clock, with unbalanced circulation and a low refrigerant level, this can put the system under strain. Ice can accumulate on the evaporator coils when this happens. You should switch off the unit temporarily while you determine the best way to address the problem.
    • If buying a new air conditioner is the right approach, it is wise to seek expert guidance. This way, you are more likely to select a suitable unit for your circumstances. Depending on the layout of your property and your preferences, the best options could be any of the following:
    • A central air conditioning unit is recommended if you want to cool your entire home. However, if you only want one or two rooms cooled, room AC units are ideal. Properties that already have the proper ductwork will benefit from a split system. This divides the outdoor condenser and compressor and might be the most suitable choice.
    • Lastly, evaporative coolers are perfect if you live in a dry climate because they cool the air down using evaporated water.

    Why HVAC Repair Is So Important

    Once you become aware that your air conditioner is out of power, you should inspect the breaker and the wiring. If these look OK, there might be something else that is causing them to overheat. Common AC repair tasks are to redo the circuitry and wiring and ensure the outdoor unit has clean airflow running to it. To cut down the number of issues that might arise, you should have your air conditioner maintained frequently. By doing this, you will keep your system running at optimum efficiency and prolong its lifespan. Also, whenever you have problems with your air conditioner, it is sensible not to depend solely on an expert. Rather, you should make an effort to look for information and learn basic maintenance tasks yourself. This way, you will not be stressed if something goes wrong.

    Arrange a maintenance visit at least once per year with an engineer, and inspect the unit yourself each month. While doing this, you should monitor the refrigerant, give the unit a clean, and ensure it is safe and operating smoothly. You will have to repair your air conditioner if any of the less obvious problems listed below have arisen:

    • You should be able to determine whether you have a worn-out fan belt. The noise your unit makes while it is running can reveal whether this is the case. If you hear a squealing sound, then — rather than repairing the unit – you should have it replaced. If it keeps making progressively louder noises, it is severely damaged and costly to repair.
    • To deal with an air conditioner that leaks refrigerant, it is important to act swiftly. If you fail to do this, you will make your unit less efficient and damage the surrounding environment. As well as recharging the system, you will have to adjust its tubing to stop the leaks from happening. Leaks can cause a lot of damage if left unattended.

    Recommended AC Repair Equipment

    It is wise to have a selection of tools to repair your air conditioner if required because you never know when something might go wrong. If your unit stops working, the last thing you want to do is to bother your neighbors at an unsociable hour. Owning your tools gives you a degree of independence and self-sufficiency. Also, it makes sense to invest in some tools because it allows you to prevent more serious problems from developing, costing you a lot of money. The best tools for repairing air conditioners are nut drivers, needle/nose pliers, voltage testers, ratchet/socket sets, adjustable wrenches, multimeters, insulated screwdrivers, and cordless drills/drivers.

    Recommended AC Repair Materials

    Here is a selection of materials that are ideal for AC repair. These materials can help you resolve any problems that you are likely to encounter with your unit. They are as follows: fuses, contactor, condenser fan motor, and air compressor capacitor. Take heed of the above advice, and your air conditioner will last for much longer.
