5 Common Reasons Why Your AC is not Working

In this modern world, air conditioners are everywhere. And, if you live in a place with hot summers and cold winters, an air conditioner is a must-have appliance. However, as much as we rely on them to keep us comfortable no matter the weather or season, we often forget them – or even think about cleaning them. Like any other appliance in your home, your air conditioner needs to be serviced and cleaned regularly, especially when it stops working as efficiently as it used to.

Choosing a reliable and licensed HVAC contractor is the best option to go when deciding to get an air conditioning installation and thermostat installation for your failing home cooling system. Unfortunately, despite our efforts to ensure that our home cooling unit is in perfect working condition, issues still occur that greatly affect the overall performance and functionality of the air conditioner.

What’s more stressful is knowing that your AC unit is not at its best, but you have difficulty determining the exact problem. Because an air conditioning unit is a piece of complicated machinery, it requires a lot of attention and knowledge that only an experienced expert can provide.

Refer to the following list of possible reasons why your AC is not working:

  • Electrical wiring problems – Electrical wiring issues are highly common among electrical machinery like AC units as household cooling systems work for prolonged periods. A short-circuited, burnt, or tangled wiring system could induce serious damages to the system unit rendering it inoperable.HVAC Contractor | HVAC Alliance Expert
  • The evaporator coil has broken – A broken evaporator coil can cause difficulty in converting indoor air to cold air. If such a problem is left unresolved, it could escalate and cause more damage to the entire cooling unit.
  • Clogged air filter If the air filter is clogged, air cannot get through the AC system and gets converted to cold air, which is then released. Such a problem might also clog the cooling fans rendering them unusable.
  • Refrigerant leak – A liquid refrigerant is used to convert the indoor air to cold air. If there is a presence of a leak in the refrigerant container, it could leak, which could cause severe temperature issues in the air conditioner.
  • Faulty thermostat – The thermostat of the air conditioning unit is responsible for regulating the temperature released by the equipment. It controls when the AC system should and should not convert indoor air and convert it to cold air. If anything bad happens to the thermostat, it is expected that heating and cooling problems will emerge, which could permanently damage the cooling equipment.

HVAC Maintenance | HVAC Alliance ExpertAC Maintenance Checklist

Having a fully functional home AC unit that is free from malfunctions and damages is truly something that’s hard to come by as reliable AC maintenance providers are difficult to locate. So when you know of one, it is ideal for taking advantage of it.

AC maintenance is important to ensure that your household cooling system is always in its best condition and is working without any problem. Below are the following reasons why AC maintenance is important in maintaining the order and condition of your AC unit:

    • Lower electric bill – Many AC problems often contribute to your increased monthly electricity bill as certain malfunctions trigger your AC unit to consume more electricity than normal. Such a problem could cause larger electricity expenses and induce severe damages to the AC unit, rendering it inoperable if the problem is left unresolved.
    • Health and safety concerns – AC units accumulate dirt and dust over time, especially when it is often used. If the AC unit lacks regular maintenance checkups and cleaning, the air filter could fail to perform its job of filtering the air. Such a problem could have an effect on the health of everyone using the AC unit.Air Conditioning Installation | HVAC Alliance Expert


  • Extend the life of the AC unit – By getting your AC unit serviced regularly, underlying malfunctions and damages are detected earlier, which gives the user enough time to resolve the issue before it escalates to something more damaging.
  • Comfortable environment all the time – Regular maintenance check ups ensure that your AC unit is always at optimal working condition. As a result, a comfortable and conducive environment where families may rest easily is maintained at all times.
