Top 10 Causes of AC Breakdowns | Custom Air System Skip to main content

When you live in a hot climate like Houston, Texas and the surrounding area, you depend on your air conditioner to keep you cool during the summer months. Unfortunately, summer air conditioner problems are caused by maintenance issues and common mechanical failures that may be avoided with maintenance services. Here are 10 of the most common problems that require 24 hour a/c repair.

Your Air Conditioner Overheats


It happens every summer; your air conditioner is running all day long because of the heat, and suddenly it trips a breaker. Don’t be the typical homeowner and simply reset the breaker; call for a/c repair to ensure there isn’t a more significant issue.

You Didn’t Keep up with the Maintenance


Regular maintenance is important for just about everything; your home, your car and yes, your a/c. You can schedule regular maintenance with your HVAC technician and save yourself money in the long run.

The Air Conditioner is Old


Eventually, your air conditioner will need to be replaced, and older units tend to quit when you need them most because the heat causes them to work harder.

Your Low on Refrigerant


It’s not uncommon for older units to develop refrigerant leaks which can cause your a/c to stop working when you need it most. Regular maintenance can help prevent this.

The Condenser Coils are Dirty


Dirty condenser coils mean the coils can’t remove heat from the air which affects your a/c’s ability to cool, and in some cases can stop it from cooling altogether.

You Never Change the Filter


Never changing your a/c’s filter decreases the amount of air flow through the inside and outside units. This decreases your air conditioner’s efficiency and can cause other, bigger problems.

The Evaporator Coil is Frozen


A frozen evaporator coil is usually the result of not changing your a/c’s filter and frozen coils can’t absorb the heat from the air circulating around them.

You Have a Clogged Drain Line


If the drain line to your a/c unit is clogged, the water the unit removes from the air has nowhere to go and can damage the system.

You Need a New Thermostat


Older thermostats can send the wrong information to your a/c unit because it’s incorrectly calibrated. Newer thermostats can be difficult to program, so check your settings and make sure you have it programmed correctly.

Your Ductwork is Leaking


The ductwork throughout your home may have holes and other damage which means the air your HVAC unit is producing isn’t getting past your walls, making your a/c work harder than it should.
