Every June, the same thing happens to homeowners across Tyler and East Texas. The temperature climbs, the thermostat gets pushed a little lower, and a few weeks later a power bill arrives that looks like a typo. The instinct is to blame the utility company or assume it is just the cost of a Texas summer. Sometimes that is true. But more often, the culprit is an air conditioning system working significantly harder than it should be, costing you real money in the process.
Understanding why that happens, and what you can actually do about it, starts with how your AC system works when the heat gets serious.
Your AC Does Not Cool Your Home — It Removes Heat
This is the piece most homeowners miss. An air conditioner does not generate cold air the way a furnace generates heat. It moves heat by pulling it out of your indoor air and releasing it outside through the refrigerant cycle. The harder your system has to work to keep up with the heat load inside your home, the longer it runs, and the more electricity it consumes.
In Tyler and East Texas, that heat load gets serious fast. High humidity makes the air feel hotter than the thermometer reads, which means your system is simultaneously fighting two problems: temperature and moisture. A system that is even slightly underperforming gets exposed quickly when conditions like that stack up.
Five Reasons Your AC Is Driving Up Your Electric Bill
Not every summer spike is your AC’s fault. But if your bill is climbing year over year without a clear explanation, one or more of these is almost certainly involved.
1. A Dirty or Restricted Air Filter
This is the most common and most fixable cause of efficiency loss, and also the one most homeowners overlook. A clogged air filter restricts airflow through the system, forcing the blower to work harder and reducing the amount of conditioned air reaching your living space. Your system runs longer to hit the same target temperature, and your bill reflects every extra minute.
During summer in East Texas, filters can load up faster than the standard recommendation of every 30 to 90 days would suggest, especially in homes with pets, dusty conditions, or high occupancy. Check yours monthly from June through September.
2. The System Is Low on Refrigerant
Refrigerant is the substance that actually carries heat out of your home. When a system develops a leak and refrigerant levels drop, its ability to transfer heat drops with it. The compressor compensates by running longer, pulling more power, and still delivering less cooling than it should.
Low refrigerant is not a DIY fix. It requires a licensed technician to locate the leak, repair it, and recharge the system properly. If your home takes longer than it used to reach your set temperature, this is worth investigating. An AC repair call now is far less expensive than the compressor damage that can follow a refrigerant issue left unaddressed through a full East Texas summer.
3. Dirty Evaporator or Condenser Coils
Your system has two coil sets: the evaporator coil inside that absorbs heat from your indoor air, and the condenser coil outside that releases that heat. Both accumulate dirt and debris over time, and both lose efficiency when they do.
A coated evaporator coil cannot absorb heat efficiently. A condenser coil buried in cottonwood seed, grass clippings, or general outdoor debris cannot release heat efficiently. Either condition forces the system to run longer and pull more power. Coil cleaning is part of a thorough annual maintenance visit and is not something most homeowners can effectively do themselves.
4. An Aging System Past Its Efficiency Peak
Air conditioning systems are built to perform at their best when they are new. As they age, that performance erodes, not all at once, but gradually and consistently. Capacitors weaken, motors develop friction, coils accumulate film, and refrigerant levels drift. Every one of those small changes means the system is drawing more power to deliver the same cooling it once handled without working as hard.
The efficiency gap between an aging system and a modern replacement shows up on your electric bill every month it goes unaddressed. If your system is more than 10 years old and your summer bills keep climbing, the math on a new system, especially with financing options spread over 72 months, is worth running.
5. Duct Leakage You Can’t See
Your ductwork moves conditioned air from your air handler to every room in the house. Older East Texas homes frequently develop gaps, separations, or deteriorating seals in their ductwork. When that happens, a meaningful percentage of that conditioned air never reaches its destination. It bleeds into attic space, wall cavities, or crawlspaces instead.
The result: your system runs longer to compensate for air it is effectively losing. Duct cleaning and inspection can identify where that leakage is happening. In severe cases, duct sealing or replacement is the fix, but you cannot solve a problem you have not located first.
The Thermostat Factor
Before calling a technician, it is worth ruling out one variable: how you are using your thermostat. Keeping your home at 68 degrees all day while you are at work is one of the fastest ways to drive up a summer bill. Your system runs almost continuously trying to maintain that gap between indoor and outdoor temperatures.
A programmable or smart thermostat lets you raise the temperature while the house is empty and recover it before you return, without the system running flat out all day. Over a full Tyler summer, the difference between a system running continuously at a fixed low temperature and one that adjusts intelligently throughout the day can be substantial on your monthly bill.
What a Tune-Up Actually Does to Your Bill
The most direct lever most homeowners have over their summer energy bills is annual AC maintenance. A proper tune-up goes well beyond swapping a filter. A full inspection and service visit addresses several of the efficiency drains listed above in a single call.
An Evans Air technician will check refrigerant levels, inspect and clean coils, test capacitors and electrical components, verify airflow, and give you an honest read on how your system is performing versus how it should be. If something is pulling your efficiency down, you will get a clear picture of what it is, what it costs to fix, and what it is currently costing you on your electric bill every month.
Evans Air currently offers a $49 HVAC Tune-Up and Safety Check, a practical starting point if your bills have been climbing and you want a clear picture of why. Check the Evans Specials page for this and other current offers.
When the Bill Is Telling You Something Bigger
A rising electric bill does not always point to a maintenance issue. Sometimes it signals that the system itself needs to be replaced. If your system is more than 10 years old, has needed multiple repairs in recent seasons, and your bills keep climbing despite regular upkeep, the system may simply be past the point where maintenance can recover meaningful efficiency.
That is a conversation worth having with a technician you trust. Evans Air has been serving Tyler, Longview, Lindale, Whitehouse, and the surrounding East Texas area since 1978. When we look at your system, we will tell you honestly whether the path forward is a repair, a tune-up, or a new system, along with what each option looks like on a monthly basis with current financing in place.
Start Here
If your electric bill has been higher than it should be and you want to know why, a $49 tune-up is the lowest-cost way to get a complete answer. If your system is already struggling, do not wait for a full failure in peak heat.
