Reasons why an HVAC is running but not cooling

Jumping to conclusions has never been the best approach and especially when dealing with electrical appliances like an air conditioning system. A malfunctioned HVAC could be a sign that you need a new system, to clean the parts, or even just switching it on or off, etc.  Some common reasons conditions that have been associated with operational faults are:

  • The coils in the air filter are dirty and clogged– the air filter is often the first part that is checked if the unit is not performing its chief objective. A clogged air filter restricts the flow of air, which in turn affects the functionality of the unit. The solution can be as simple as removing the clogging elements.
  • The batteries are dead– you may not have thought about this, but it is a possible cause. The solution is getting a new set of batteries.
  • The indoor and outdoor disconnect switches are off

Again it could as simple as the switches could have been touched accidentally, and turning on will solve the problem.

  • There is a circuit break/ The fuse has been blown 

Electrical issues are common. If you identify this as the cause, look for the breakers, most units have two or three, turn them off, then on and see if is it restores the state. For a blown fuse, consider seeking professional assistance.

  • Improper installation 

The signs of poor installation may be visible, for example, hanging sections. Other times, they are unseen by those who have limited knowledge about the unit.  In such a scenario, you can always seek professional HVAC repair services like ARS – Rescue Rooter.

  • Thermostat set to “ON” instead of “AUTO.”

The wiring is tied to the back of the unit; in that case, contact a licensed HVAC professional for assistance. Sometimes you may need to replace the electrical board or install a new thermostat.
  • Dirty unit – the inside unit, an evaporator, absorbs heat from the house and air transfers to the outside unit, the condenser. However, if it hosts foreign matter, the rate of circulation is affected. To remove debris such as leaves, remove the fan case using a screwdriver and put the grill aside. Taking the necessary precautions as you clean it.

Safety Tips when handling HVAC

There is a common assumption that one should only wear protective gear when dealing with complex electrical issues; this is wrong. In all cases, ensure that you and the people around you are safe.  Danger can strike any time; this is not meant to scare you but rather make you consider safety precautions all the time. Here are some measures you should undertake when handling an HVAC:

  • Assess the situation-depending with the cause of the operational challenges; the safety precautions will vary. While jumping on the task can be tempting, especially among those who want to show their expertise, it is not always the right move. To be on the safe side, assess the situation extensively; this includes consulting an expert, using the manual, etc.
  • Make protection your priority- this includes wearing protective equipment when handling the unit. The first thing is to shut off the power when handling the unit in the interior and exterior sections. For example, when    cleaning dusty surfaces, always wear gloves and nose masks.
  • Learn about chemical safety-before embarking on cleaning tasks or adding refrigerant, learn about safety precautions. Some chemicals, if improperly used, can explode and cause major injuries to the handler and the people around. In extreme cases, the explosive can destroy the HVAC. Always wear protective gloves and other safety gear like goggles and masks to prevent skin irritation, burns, inhalation, etc.
