Duncanville FAQ

Why did my AC bill go up even though I haven't changed the thermostat?+

It's often a gradual decline in system efficiency, duct leaks, or a building envelope issue like sun exposure and insulation, rather than a single obvious cause. A diagnostic can identify which factor is actually driving the increase.

Does an oversized AC system cost more to run?+

It can. An oversized system cycles on and off frequently without properly dehumidifying the home, which can leave it feeling clammy and prompt a lower thermostat setting to compensate, using more energy than a correctly sized system would.

Is there anything specific to Duncanville homes I should know before calling?+

Nothing that changes the fundamentals, just let us know you're in Duncanville and what you're seeing, and we'll take it from there with the same honest diagnostic we bring to every call.
