Major Causes Of Broken HVAC Units

Though there may be hundreds of issues as to why your Indianapolis air conditioning unit may need to be looked at by a proficient contractor, there are some mechanical problems that are commonplace. Being able to identify with these problems can make your service call much easier.

There are common issues that can cause systems to malfunction every day. Here are the top 5 reasons for an AC system failure.

Indianapolis Heating-and-Cooling-Services1. Defective Wiring

Poorly run, jumbled or uncertified A/C wiring is dangerous and increases the likelihood of a fire. Poor wiring can thwart the system from receiving power, or it can kick the circuit breaker.

2. Low Freon

Freon is commonly called refrigerant in the HVAC industry. It is the chemical that cools the air in the unit. If levels are low, this could imply that there is a leak or a problem with the system.

When a system needs to be recharged, it usually indicates a leak. Leaks need to be located and repaired.

3. Fan Isn’t Working

The fan is in charge of handing over the heat from your Indianapolis home to the outside. When the fan isn’t working correctly, the heat transfer cannot take place. This can cause the compressor to overheat and trip the breaker.

Even worse, it can cause the compressor to have internal damage. Replacing a compressor is very costly.

4. Unit is not Functional

There are several reasons why a unit won’t function. It can be a loss of power, a faulty thermostat, an electrical issue or many other things.

5. A Frozen Coil

Ice on the unit indicates a problem with airflow. This can be caused from a dirty air filter or an obstruction in the duct work. A coil that is frozen indoors can be from a low Freon level in the unit. This can indicate a leak if the Freon is too low.

Also, turning the AC unit down to unrealistically low numbers, like 60 degrees, will cause it to run continuously. A unit that never shuts off is at an increased risk of freezing up.

The best way to thwart a mechanical issue is to have a preventative maintenance program in place. Issues like poor wiring, bad airflow and refrigerant leaks can all be found during these tune-ups. When dealing with these common problems, it is best to have a professionally qualified technician who can quickly access the problem and perform any repairs.
