5 Ways to Tell if your A/C is Costing YOU Money

The average Texan pays roughly 10.98 cents per kilowatt hour (kWh) with an average use of 1,171 kWh per month. This is equivalent to paying approximately $128.50 a month and roughly $1,542 annually to your local ‘lovely’ electric utility company. Now, on a per kWh basis, living in Texas has its benefits as the 10.98 cents per kWh is 7.58% less than the national average of 11.88 cents per kWh. However, as many of you all are aware, that Texas heat can be brutal. While rates per kWh are fairly low, because of Texas’ climate and the lifestyle us Texans are accustomed to living, the average monthly electricity consumption in Texas is 29.35% higher than that of the national average. Lower rates being offset by higher consumption causes Texans’ average monthly bill to be 19.63% higher than the national average. Heating and cooling energy consumption makes up more than 50% of a home’s energy consumption. Just think how much money you would be giving away if your air conditioning unit was inefficient. 

Let’s give a short example. East Texas typically has 1,986 cooling degree days which essentially is electric utility industry lingo for a good amount of time the weather is above 65 degrees. A home with an AC tonnage of 3.0 that is currently fitted with a 13 SEER unit will cause the 13 SEER unit to consume roughly $597 of electricity per year. That same exact home fitted with a 19 SEER unit will have roughly $409 in electricity consumption related to cooling load each year. The 5-year savings $940. The 10-year savings is $1,880 and the 15-year savings is $2,820. Remember, A/C units that are professionally installed and professionally maintained typically have a lifespan of 10 to 15 years. The price differential between a 13 SEER unit and a 19 SEER unit does not cancel out the savings. It saves to run a more efficient unit even with the initial upfront costs of purchasing it so long as the dweller plans to stay in the house long enough to see the payoff or it can be a good home selling point.

Most College Station Residents are able to save by choosing Higher SEER rated Installation and Equipment. Going with 18+ SEER rated can even pay up to $800 per System while rebates like this are in effect. Currently replacing an old Heater or Air Conditioner has the following levels of Rebates offered by the city of College Station in 2019. Condenser and coil must be included in the replacement. Furnaces are usually a 3rd piece in which some homeowners need often depending on weather or not their home is connected to a Natural Gas.

  • Up to $500 for 15 SEER+

  • Up to $600 on 16 SEER +

  • Up to $700 on 17 SEER +

  • Up to $800 on 18 SEER +

Other discounts and Rebates for those who in the Greater Houston Area can call can check their eligibility as well.

As you might have concluded, one way to tell if your A/C unit is costing you money is by continued high electric bills. If you see incrementally higher electric bills without noticing a shift in your lifestyle or significant weather fluctuations, it is likely that your A/C unit is inefficient and could use the professional eye of EcoZapp. An inefficient A/C system must worker harder to maintain the cool temperature in your home. This will be evident when you start to receive high electric bills. Your wallet will thank you for calling EcoZapp . 

Frequent cycling of your AC is another money waster. This could be related to the A/C unit’s compressor or could be a sign of dust damaging the thermostat’s internal mechanism. The thermostat is the wizard behind the curtain when it comes to a home’s cooling system. If you can tell your unit is going on and off with great frequency, the thermostat may need to be replaced or as mentioned before, it could be a compressor issue. Either way, cycling on and off causes a greater electric demand in kW and consumption in kWh which all translates to lost dollars from your bank account vanishing into thin air. It is imperative that all components work in a smooth fashion to maintain efficiency and to keep those dollars in your own pocket rather than the electric utility’s pocket.

An absolute sure sign that your A/C unit is inefficient is ice build-up. If you see this,  call a licensed HVAC company to handle this type of issue. Ice build up is an indicator of a leak in the A/C’s coolant or damage to the coils. It could also be related to a clogged filter. A clogged filter has the ability to interrupt airflow and circulation which is a system causation of an overheated system. You may notice ice on the exterior of the unit. Basically, there are a variety of reasons for ice build up that require a professional to fix and mitigate the problem going forward.

When you find yourself spending more time in a particular room simply because of its cool temperature, that’s a sign of uneven cooling. Uneven cooling is a clear sign of an inefficient A/C operation. Obviously, direct sunlight plays a role in certain rooms being warmer than others as well as second-story areas being warmer than other parts of the house. However, if the A/C unit is running optimally, then all of those rooms and areas should feel comfortable. Taking care of this issue will not only allow you to enjoy your entire house, but it will save you money because the unit will not have to work as hard to try to keep a specific area cool.

If air in the home feels moist or clammy, it is a surefire sign that the A/C unit is not performing the way it was intended. It is an air conditioners job to pull moisture out of the air. In fact, that’s a key component of how air conditioners cool a home. If that is not happening, then EcoZapp can step in to come up with the optimal solution for you and your home.


As a bonus notifier and mostly a safety tip, if you hear unusual sounds from the A/C unit, it is best to go ahead and shut it down. Banging, clanking, or rattling sounds are a strong indicator of a component being broken or an electrical issue. It is better to be safe than sorry when it comes to unusual sounds in an A/C unit. The A/C unit is designed to fly under the radar so if it is drawing attention to itself then there most likely is a problem.

The road to energy efficiency is, in theory, a sustainability sweepstake. More efficiency means that less fuel is required to generate a given amount of energy, which in turn means lower costs for the provider and cheaper prices for the customers.
