Why this calculator exists
The hardest part of a high bill is not knowing
Customers call us all summer with the same question: "is my AC the reason my bill jumped?" Sometimes it is. Sometimes it's the weather, the kids being home, or the thermostat schedule. Either way, the worst feeling is staring at the bill with no idea where to start.
The math is real
The expected-bill calculation pulls from typical Houston-area cooling cost per square foot, adjusted for thermostat set point and system age. A 2,000 sqft home with a 12-year-old AC at 76°F runs around $260-300 in a normal August. Big deviations from that almost always trace to one of seven or eight things.
The likely-causes list is what we'd actually check
Filter, capacitor, dirty coils, refrigerant, duct leakage, oversized system, failing compressor, thermostat. That's the list, in roughly the order our senior techs work it on a real diagnostic call. The calculator surfaces the most probable two or three based on your numbers.
Straight answer, even when it's "your system is fine"
Calculator says your bill is normal? We tell you so plainly. Repeat business and word-of-mouth keep us alive, so the answer that fits your situation is the answer you get.
Common questions
How accurate is the diagnosis?
It's a starting point, not a diagnosis. The math compares your bill to what a typical Houston-area home of your size, age, and thermostat setting should run in summer. The likely-causes ranking uses age + severity to surface what we'd check first as techs. Real diagnosis still needs gauges, an amp meter, and eyes on the unit.
What if my bill is in the normal range?
Then we tell you so plainly. Most homeowners who use this calculator after a sticker shock find their bill is normal but they hadn't realized how much weather, set point, or schedule changes affect cooling cost. If yours comes back normal we'll point you at the cheap things to check (filter, thermostat schedule) and not push you to schedule a paid visit.
What does the diagnostic visit actually look like?
$99 flat ($79 for new customers, $20 off your first service call). A senior tech walks the system: outdoor coil, indoor coil, refrigerant pressures and superheat/subcooling, capacitor and contactor health, drain line, blower, ductwork pressures and leakage indication, and the thermostat program. You leave with a written report listing what's healthy, what's borderline, what's failing, and the price to fix any of it. The diagnostic fee is applied 100% to the repair if you proceed.
How fast can someone come out?
Most weeks we have same-day or next-day availability across Pearland, Friendswood, League City, Alvin, Manvel, and the surrounding ZIPs. During heat waves the window stretches to 1-3 days. We're 24/7 for emergencies (no-cool calls).
What if it turns out to be a small fix?
That's the best outcome and we'll tell you so. Plenty of "my bill is high" calls turn into a $40 filter, a slightly clogged drain pan, or a thermostat schedule that wasn't doing what the homeowner thought. You get the answer either way.
