Help! Why Is My Air Conditioner Making Clicking Noises?

top reasons your ac broke

Spoiler alert: That’s not supposed to happen

Even the quietest modern air conditioners make some noise as they cool your home, but there are some sounds your AC just shouldn’t be making. Clicking, banging, clanking and hissing sounds are signs of trouble, and if you hear them, you’ll need to take action to identify and resolve the problem. Here are some common indicators of AC maintenance issues.

First, listen for vibration noises. A humming sound generally isn’t an indicator of a serious issue, but it probably means that something inside your air conditioner is slightly out of order. Loose parts and too-tight refrigerant piping can cause vibration, and if left unchecked, lead to a more serious maintenance issue.

Buzzing or humming could also be a sign of an electrical problem with your air conditioner. Shut off the power and check around the wires for any signs of corrosion, rust or other damage. If … Read Full Post »

The Best Thermostat Settings for Summertime Energy Savings

Dial up the temperature to dial down your costs

Everyone wants to keep cool all summer long, but there’s no need to pay extra for that privilege. There’s plenty you can do to cut the energy usage of your air conditioning system without compromising comfort, and probably the simplest way is to just adjust your thermostat.

The rule of thumb for summer thermostat settings is to set it as high as you can without becoming uncomfortable. For most people, that’s somewhere in the 76-79 degrees Fahrenheit range. Turning your thermostat up by one degree cuts your energy usage by about 8%, so it pays to make that adjustment even if it’s just from 72 to 73. Experiment with different settings and find your family’s sweet spot.

One way to make it easier to set your thermostat higher is to invest in ceiling fans. Fans make the air feel cooler by producing a breeze … Read Full Post »

Many homeowners don’t put much thought into choosing a thermostat for their San Antonio AC unit. You might think that all thermostats are alike or that a thermostat can’t have a … Read Full Post »

How to Keep Your Air Conditioner Running Smoothly All Summer

But it can be prevented.

All you need to do is give your air conditioning unit a little Texas love and hospitality.


Houston, We Have a Problem. Don’t Take Your Air Conditioner for Granted.

Texans love air-conditioning in summer, so it’s important to perform regular maintenance. Don’t forget that your AC system has working parts that need attention.

Austin’s Climate Affects Your Budget in a Big Way

Hot summer days bring oppressive electric bills

The city of Austin is known for its beautiful parks, thriving economy and exciting music events. Unfortunately, it also has a seasonal climate that produces costly and unpredictable utility bills. High temperatures regularly exceed 100 degrees during the summer, yet they can fall below freezing in December and January.

Hot Weather

Austin’s lengthy summer persuades just about everyone to use air conditioning. During 2011, some parts of the state capital reached 100 degrees on 90 separate days. Extremely hot weather seldom occurs before June or after September. Nonetheless, the Bergstrom International Airport once reported a 100-degree reading in February!

Central Texas summers aren’t just hot. This area also endures greater humidity than the Lone Star State’s more arid locales, such as El Paso and Lubbock. Austin’s skies often remain clear in July and August, adding extra heat to the upper floors of many buildings. The local power … Read Full Post »

What to Consider When Making Energy-Efficient Cooling Updates

Keeping your San Antonio home cool during the hot summer months can be a real challenge. Like many homeowners, you might worry that keeping your cool will simply cost too much. Thankfully, new options in energy-efficient cooling can help you stay comfortable all summer without breaking the bank.

Understanding Your Energy-Efficient Cooling Options

When it comes to energy-efficient heating and cooling options, you have several types of systems from which to choose. Before you start shopping for a new system, you’ll need to understand that you can choose from:

• Central air systems, which use HVAC units paired with ductwork to move treated air throughout a home.

An HVAC specialist can help you decide which type of system is best suited to your needs. Many homeowners now prefer ductless systems because they don’t require any structural … Read Full Post »
