Summer cooling can be a large part of a Houston electric bill. The useful question is how much of the usage comes from weather and thermostat settings versus duct leakage, attic/envelope load, equipment performance, or other electrical loads.
High bills can have multiple causes. We compare energy use with the home, HVAC system, weather pattern, and comfort symptoms before recommending improvements.
A sun-heated roof can raise attic temperatures well above outdoor air temperature. The amount that reaches the living space depends on insulation, air sealing, roof/attic configuration, duct location, and other factors.
Low, uneven, or disturbed attic insulation increases heat transfer through the ceiling. Recommended insulation levels depend on the existing assembly, climate guidance, and the condition of the air barrier.
ENERGY STAR reports that in a typical house about 20–30% of the air moving through the duct system can be lost through leaks, holes, and poor connections. The actual leakage in a specific home should be tested rather than assumed.
When building load and distribution losses increase, cooling runtime generally increases. But the electric bill also includes thermostat settings, equipment efficiency, pool equipment, water heating, appliances, and rate structure, so we do not attribute the whole bill to HVAC without looking at the data.
The fixes aren't complicated — but you need to know which ones will actually move the needle for your specific home.
We measure attic conditions, insulation levels, duct leakage, and system runtime in your home. That tells us exactly where the energy is going and which fixes will deliver the most impact per dollar spent. Learn about our energy assessment.
A radiant barrier can reduce radiant heat transfer from the roof toward the attic and ceiling. Its effect depends on installation, roof/attic conditions, insulation, ventilation, and where the HVAC equipment and ducts are located. Learn about radiant barriers.
Adds insulation where the existing level and coverage are inadequate and pairs it with air-sealing where appropriate. The target R-value should be based on the home and current guidance rather than a one-size-fits-all number. Learn about blown-in insulation.
If duct leakage is significant, fixing it is one of the fastest ways to reduce runtime and bills. We test and measure before recommending any duct work. Learn about duct design.
High summer bills can come from cooling load, duct leakage, equipment performance, thermostat settings, pool equipment, water heating, appliances, and utility-rate structure. We focus on the loads Suntex can actually measure and improve rather than assuming the AC is responsible for the entire bill.
Savings vary widely by home and scope. We do not promise a fixed percentage. Weather, thermostat settings, duct leakage, insulation, equipment efficiency, and other household loads all affect the result.
Solar can offset energy consumption, but if the underlying home has high energy losses, the offset often doesn't match projections. We advise many Houston homeowners to fix the home first — insulation, ductwork, radiant barrier — and only then evaluate solar, because the return is much better once the waste is eliminated.
There is no universal “fastest” improvement. If testing shows major duct leakage, insulation gaps, air leakage, or equipment problems, those may have higher priority than a radiant barrier. The sequence should follow the measured losses in the home.
A diagnostic assessment shows you where the energy is going and what will actually reduce it.
