Top 6 Reasons for Air Condi-tioner Issues

INSERT THE TITLE OF YOUR PRESENTATION HERE

Intro

If you’ve ever spent a hot summer in India in a home or business plagued with air condi-tioner problems, it’s certainly an experience you don’twant to repeat. Don’t leave your summer comfort to chance! Learn about the most common causes of air conditioner problems and the easy steps you can take to prevent repair issues.

1. LOW REFRIGERANT

The refrigerant is the stuff that your airconditioner uses to remove the heat and humidity from the air in your home orbusiness. If your system develops leaks in the refrigerant lines, you can end up with not enough refrigerant to effectively cool the air. Unfortunately, fixing this air conditioner problem correctly is not just a matter of replacing the refrigerant. An HVAC technician needs to find the leaksand repair the holes in the lines, which can sometimes be a time-consuming and expensive process, especially when there are multiple leaks.

2. FROZEN EVAPORATOR COILS

Your air conditioner’s evaporator coil isfilled with refrigerant, and is responsible for absorbing the heat from the air like a sponge. It may sound counter-intuitive, but those coils need warm air circulating around them to work properly. When something goes wrong with the airflow and the evaporator coil gets too cold, a layer of ice can build up on the outside. When that happens, you’ll get warm air or none at all coming from your air conditioning supply registers.

3. FILTHYCONDENSER COILS

Your unit’s condenser coils, part of the outdoor unit, gets rid of the heat removed from the air by expelling it outside the building. The condenser coil won’t work well when it getscovered with a layer of dirt and grime. This is a very common problem in India with all the soot and pollution in the air. When it happens, heat transfer is impeded, and your unit has to work harder to do its job, leading increased wear on the parts and even system failure.

4. FAN PROBLEMS

There is a fan that blows indoor air over your unit’s evaporator coil to cool the air, and another that blows air over the outdoor unit’s condenser to expel the absorbed heat outside the building. If either of those fans isn’t working properly– due to a faulty motor, lack of lubrication, worn belts or too much dirt and debris– you end up with poor airflow and air conditioner problems. If you neglect the problem, it can lead to compressor failure, which is often a death sentence for your air conditioner.

5. SPILLING DUCTS

The ductwork that runs through your walls and ceilings carries the cooled air from the air condi-tioner throughout your space. However, if there are holes or breaks in the ducts (which can be caused by rodents or careless workers), that expensive cooled air winds up inside your walls where it’s not doing anybody any good. And, of course, this scenario causes your air conditioner to work harder and drive up your energy bills.

6. THERMOSTAT PROBLEMS

Especially if you still have the old dial-type thermostats, they could be incorrectly calib-rated, which means your air conditioner isn’t getting the right instructions from the control system. This problem is fairly easy to fix by replacing or recalibrating your thermostats. If you have new programmable thermostats, sometimes these are tricky to program and they may be set incorrectly. If you still have the manual, check the instructions to make sure your thermostat’s settings are correct.
