What is the single biggest thing I can do?

In most Houston homes, sealing and insulating the attic, followed immediately by sealing the ducts running through it. Those two determine how much work your system has to do all summer. Everything else is optimization around them.

Will a new high efficiency system lower my bill?

It can, and it is the most expensive item on the list and the one most affected by everything above it. Replace equipment before sealing the attic and ducts and you will size the new system for a load you were about to reduce.

Does closing vents in unused rooms save money?

No. It raises system static pressure, reduces total airflow, and pushes more air out of any leaks in the duct system. In our climate it also leaves a closed room warm and damp, which is a different problem you will end up calling about.

Should I leave my thermostat at one setting all day?

In Houston a modest setback beats a deep one. A deep setback lets the house take on both heat and moisture, and pulling that moisture back out takes long runtime in the evening. A few degrees while you are out is usually the better balance.

Does my AC use less power if I set it warmer?

It runs less, and runtime drives the bill. The catch here is that less runtime also means less moisture removed, so a warmer setpoint only feels good if humidity is already under control. That is why the two belong in the same conversation.

How to Save on Energy Costs in Houston

Every company selling something will tell you their thing is where the savings are. Here is our order of operations for a Houston home, ranked by impact. We will not attach a percentage or a payback figure to any of it, because we cannot measure your house from here, and anyone quoting you one has not measured it either.

Start with the building, not the equipment

Your air conditioner does not decide how much heat gets into your house. Your attic, your ducts, and your envelope do. Replacing working equipment while the attic is under insulated and the ducts leak means buying a bigger machine to fight the same problem.

The order we would do it in

First, attic air sealing and insulation. Sealing the openings between conditioned space and the attic, then getting insulation to a consistent depth with no gaps, changes the load your system fights all day.

Second, duct leakage. A supply duct leaking into a 130 degree attic throws away air you already paid to cool, and a leaking return pulls that attic air back in.

Third, humidity control, because a dry house is comfortable at a higher setting. Fourth, airflow and maintenance: a loaded filter, dirty coil, dirty condenser, or incorrect refrigerant charge all cut capacity and extend runtime. Fifth, thermostat behavior. Last, equipment replacement, and only after the first four, because those determine the size you should be buying.

What we can actually measure at your house

We take total external static pressure, temperature split across the coil, refrigerant pressures with superheat or subcooling, register airflow, and indoor humidity over time. We look at duct connections, insulation coverage and depth, and the condensate drain.

Habits that matter and myths that do not

Leave the blower fan on AUTO rather than ON. In a humid climate, running the fan continuously blows air across a coil still wet after the compressor stops, and re evaporates the moisture the system just removed back into the house.

Do not close vents in unused rooms. Do not set the thermostat to 60 to cool faster, because it does not cool faster, it just runs past the point you wanted. Setbacks work, but a deep daytime setback lets the house take on moisture that costs real runtime to pull back out in the evening. A modest setback is the better trade here.

Why we will not quote you a savings number

There are too many variables in a specific house: envelope, orientation, shade, occupancy, duct condition, equipment age, and how you actually use the thermostat. A number pulled off a brochure is a sales tool, not a measurement.
