On this coast the grid is a design condition, not an accident
Liberty works on heating, cooling and ventilation across Pearland and the south Houston metro. Most of the equipment damage we are called to after a storm did not happen during the outage — it happened in the minutes either side of it, and nearly all of it was preventable.
Power cuts, brownouts and generators
Five situations crossed with three kinds of system. What to do while the power is off, what to check when it comes back, and the one instruction that matters most: stop resetting it.
Including the part nobody says
A portable generator will usually not run central air conditioning. The starting surge decides it, not the running load. The page says so plainly, and says what a generator will do instead.
Six things, in houses and in premises
Cooling
The long season. Central air, heat pumps and mini-splits, with the charge measured against the conditions and the plate rather than topped up on sight.
Heating
Short winters that still matter in a hard freeze. Gas furnaces combustion tested with an analyser, and heat pump auxiliary heat checked rather than assumed.
Electrical resilience
Surge protection at the equipment, measured voltage and start current, and hard-start devices where a measurement says so rather than by default.
Ducts and airflow
Static pressure, register-by-register airflow, and leakage — which in a hot attic means paying to cool attic air every hour the system runs.
Moisture
Condensate, pans, traps and float switches, and systems short-cycling so fast they cool without ever drying. The Gulf coast question.
Maintenance
Annual on houses, twice a year on premises, with readings recorded so the file shows a trend rather than a stack of invoices.
Houses and premises
Homes
Houses across Pearland, Friendswood and the south side — mostly newer, mostly with the plant in the attic, and mostly never balanced after handover. Cooling, ducts, condensate and the upstairs that gives up by four in the afternoon.
Businesses
Retail units, restaurants, clinics, offices and light industrial across Brazoria and south Harris County. Surveyed before anything is scheduled, maintained against the survey, with a record kept per unit.
What this website will not tell you
| Not stated | Why |
|---|---|
| A price | A capacitor and a full duct rework are not the same visit. You get a fixed figure on the phone once we know what is installed. |
| A response time | We will not promise two hours on the day after a storm, when the whole county is calling. |
| A saving | “Cut your bill by a third” depends on the house, the ductwork and the tariff. Nobody can know it from a web page. |
| Generator wiring | A transfer switch and the connection to a building are a licensed electrician’s work. We will work alongside one; we will not do it. |
Asked often enough to answer here
The power came back and my air conditioning will not start. What should I do?
Stop resetting it. Each attempt puts the compressor through another start against whatever is actually wrong, and repeated attempts are the most reliable way to turn a small fault into a large one. Wait out the built-in delay first — many systems will not restart the compressor for several minutes by design. Check the thermostat, which sometimes loses its programme. Reset a tripped breaker once; if it trips again, stop. And if anything smells hot or is discoloured, switch it off at the breaker and ring.
Will a portable generator run my air conditioning?
Usually not, and this is the gap between what people expect and what a generator delivers. The running load is one thing, but the starting surge of a compressor is several times that and it is the surge that decides. A portable unit generally covers lighting, a refrigerator, fans and charging — genuinely worth having, and not cooling. A generator is also never run indoors or in a garage, and connecting one to a building needs a transfer switch and a licensed electrician.
Are brownouts worse than outages?
In some ways, yes. Motors are designed for a voltage range, and below it they draw more current and get hotter doing the same work. A compressor asked to start on low voltage is the classic way to damage one, and it leaves no obvious mark — nothing trips and nothing bangs. It shortens the life of the most expensive part in the system quietly, and the failure eventually gets blamed on age.
Do I need a hard-start kit?
Only if a measurement says so. It gets a struggling compressor over its start faster and can genuinely help on a marginal supply, but it is a remedy for a specific measured problem rather than something every system should have. If somebody offers one without measuring the voltage and the start current, ask what they measured.
The house is cool but it still feels damp. Why?
Usually the system is too big for the house. Cooling and dehumidifying are two different jobs and the second only happens while the machine is running — a system that satisfies the thermostat in minutes never runs long enough to take moisture out. The other common source on this coast is return-side duct leakage in the attic, pulling hot humid air straight into the system every hour it runs.
