Air conditioning that is set at the right height, not just the right size
We are a heating and cooling contractor working across League City and the Clear Lake side of Galveston County. On this ground, how high the equipment sits above grade is part of the job, and we treat it that way.
Houses and commercial premises both. Replacements, repairs, ductwork and planned maintenance, with the readings written down and kept.
The number that decides the life of your outdoor unit is a height, and almost nobody writes it down
League City sits low and flat between Clear Creek and Galveston Bay, and the ground here has been subsiding for decades. That combination means two things for mechanical equipment. Water that arrives does not run off quickly, and the height something was installed at twenty years ago is not the height it is at now.
An outdoor condensing unit is a sealed electrical appliance with a fan in the bottom of it. Put it under water for an hour and you have a repair. Put it under water for a day and you usually have a replacement, because the compressor windings, the contactor, the control board and the fan motor have all been in salt-bearing water together.
The thing worth knowing is that this is almost entirely preventable, and cheaply. A fabricated stand or a taller pad costs a fraction of the equipment standing on it, and the decision is made once, at installation, in about ten minutes. It is the single highest-value conversation we have on this side of the county, and it is the one most often skipped.
So we start every replacement quote with two measurements: what height the equipment is at now, and what height it ought to be at. If those two numbers are the same, we say so and move on.
What we check before quoting a replacement
- The height of the existing pad or stand, measured, not estimated
- Where water has actually stood in the yard, which the owner usually knows better than any map
- Whether the disconnect, whip and line set penetration are above that
- Whether the condensate route still falls the way it did when it was built
- Clearances, because a taller stand that blocks airflow has fixed nothing
Two kinds of building, two different jobs
We work on both, and they are not the same work. A house needs a system sized to how the family actually lives in it. A commercial unit needs to keep trading, which changes what counts as a good decision.
Houses
Replacements, repairs, ductwork and maintenance for houses across League City, Clear Lake and the surrounding Bay Area towns. Most of the stock here is slab-on-grade with the air handler in the attic and the ducts above the insulation, which is its own set of problems in a Gulf-coast summer.
- Heat load calculated room by room, not copied off the old nameplate
- Attic air handlers checked for platform, primary and secondary drain and float switch
- Duct leakage and static pressure measured before anything is blamed on the equipment
- Humidity treated as a target, not a side effect — it is most of what comfort means here
Businesses
Offices, clinics, restaurants, retail units and light industrial space along the FM 518 and I-45 corridor. Commercial work is judged on uptime, so we quote on what keeps you trading and we say plainly which parts of a system are near the end.
- Packaged and split systems, ground-mounted platforms and rooftop units
- Make-up air and exhaust balance for kitchens and treatment rooms
- Planned maintenance with readings recorded and compared year on year
- Staged replacement where a whole-site swap cannot be afforded in one year
We wrote the elevation page for people who will never call us
It goes through what height actually protects, equipment by equipment: the condensing unit, the indoor air handler, the ductwork, and the electrical. It explains what a flood does to each one, what can be dried out and what cannot, and how to tell a maintenance problem from a water problem.
It also tells you where to look up your own flood zone and base flood elevation, which is public information from FEMA and from the City, and which we have no part in determining. We are a mechanical contractor. We set equipment heights; we do not certify them.
Questions we get asked most
Does the height of the outdoor unit really matter that much?
Yes, and it is the cheapest decision on the whole job. A condensing unit is a sealed compressor, a fan motor, a contactor and usually a control board in a sheet-metal box that is louvred and open at the bottom, so water does not have to get past anything to be inside it. It will stand in rain for twenty years and it will not survive being submerged. A taller pad or a fabricated stand costs a small fraction of the equipment standing on it, and the decision takes about ten minutes if it happens before the order is placed. The part that costs people money is dropping a replacement onto the old pad at the old height without anybody mentioning it.
My system was under water and it still runs. Is it all right?
It has proved that nothing has failed yet, which is not the same thing. Water leaves silt where air is meant to move, corrosion starting on terminals, and moisture inside winding insulation that takes a long time to leave. The failures that follow are delayed and look unrelated — a contactor that welds months later, a fan bearing that goes dry, a board that fails in the next humid spell — so each one gets diagnosed as its own fault and the common cause never gets written down. Our advice is one thorough inspection with the readings recorded, a note of the date and the depth, and then nothing unless something changes. We would not recommend replacing a system that is working.
Why would a replacement system be smaller than the one you are taking out?
Because the one being taken out was very probably oversized, and in this climate oversizing makes a house less comfortable rather than more. Cooling removes moisture only while the coil is wet and air is moving across it. An oversized system hits the set temperature fast and shuts off before it has dehumidified, so it short-cycles all day and the house stays clammy at a lower thermostat setting and a higher bill. We calculate the load from the house as it stands — orientation, glazing, insulation, infiltration, how many people actually live there — rather than from the old nameplate, and if that comes out smaller we explain why before you sign anything.
Can flooded ductwork be dried out and cleaned instead of replaced?
Flexible duct that has been submerged is replaced. Not dried, not cleaned. It is an inner liner, fibreglass insulation and an outer jacket, and once water is in that insulation it does not come out; what you have afterwards is a permanently damp enclosure blowing air into every room in the house. This is the point we get argued with about most and the one we hold to. Attic ducts are usually untouched by flooding, which is the one real advantage of running them up there. Under-slab duct that has taken water is a serious problem with no cheap answer, and the honest options are abandonment and rerouting rather than remediation. Where there is visible mould growth, remediation comes first and we come afterwards — that is a different trade.
Do you do drainage, pumps or flood barriers?
No, and we do not quote on them. We are a mechanical contractor: we set equipment at a height and we tell you plainly what height we think it should be at. Drainage, grading, sump and lift pumps, flood barriers and foundation work belong to other trades. Flood zone determinations, base flood elevations and elevation certificates are a matter for FEMA, the City of League City and a licensed surveyor, and nothing on this site is one. Because we have nothing to sell you on any of it, our advice about it costs us nothing either way.
Which areas do you cover?
League City, Clear Lake, Kemah, Seabrook, Dickinson, Webster, Friendswood, Texas City and La Marque.

Call and describe it. If it is something you can check yourself in two minutes we will say so on the phone rather than book a visit, and if it needs a different trade we will tell you which one.
