On June 3, ERCOT put a number on the summer everyone in Fort Bend County could already feel coming: a forecasted peak demand of about 92,211 megawatts. That's nearly 10% higher than last summer's peak and above the all-time record set in 2023.
The grid operator says blackouts are unlikely — they've added capacity, and the odds of an emergency in June sit at a fraction of a percent. I'm not here to scare you about the lights going out. I'm here because a record-demand summer means two things for every Sugar Land homeowner: your house is about to work harder than it has all year, and your electric bill is about to test your patience.
After 18 years selling homes in this market, I've learned that Texas summers don't just make you uncomfortable. They expose every shortcut, every deferred repair, and every "we'll deal with it later" decision you made about your house. The foundation, the AC, the roof — heat finds the weak point.
Here's the playbook I run on my own house, and the one I give clients every June.
First, Understand What You're Actually Up Against
Sugar Land summers are a specific kind of brutal, and it's worth naming the three forces that matter for your home:
Sustained triple-digit heat. It's not one bad day — it's eight to ten weeks of relentless load on your cooling system. ERCOT's meteorologists are calling for a summer in the range of 2012 (17th-hottest on record), with the possibility of something closer to 2023 (second-hottest) if the early-summer rain dries up.
Gumbo clay soil. This is the one out-of-towners never see coming. Fort Bend County sits on expansive clay that swells when wet and shrinks when it dries out. In a hot, dry summer, that soil pulls away from your foundation — and a slab that loses its support cracks. This is the single most expensive heat-related problem in Sugar Land, and it's almost entirely preventable.
Evening grid strain. Here's the counterintuitive part. The grid's tightest window in 2026 isn't the 3 p.m. blast-furnace afternoon — it's 8 to 9 p.m., when solar generation fades but everyone's AC is still running flat-out against a house that soaked up heat all day. That timing has real implications for your bill and your comfort, which we'll get to.
This post is about the heat specifically. If you also want the wind-and-water side of summer, my hurricane-season prep guide covers what to do before a named storm — different threat, different checklist.
Protect Your Foundation: The Sugar Land Homeowner's Secret Weapon
I'm putting this first because it's the most expensive thing on the list and the least understood. Foundation repair in Fort Bend County routinely runs $8,000 to $30,000+. Watering your foundation costs a few dollars a month.
When clay soil dries and shrinks in a Texas summer, it pulls away from the perimeter of your slab. The unsupported edge settles, and you get the classic signs: hairline cracks in drywall above doorframes, doors that suddenly won't latch, gaps opening at the corners of windows. Most homeowners blame "the house settling." It's not settling — it's the soil moving, and you can stop it.
The fix: consistent soil moisture. The goal is to keep the soil around your foundation at a steady moisture level all summer — not bone dry, not flooded.
- Soaker hoses placed 12–18 inches out from the foundation, run on a timer 20–30 minutes early morning, a few times a week during dry spells. Even, gentle moisture is the goal.
- Watch for separation. If you can see a gap opening between the soil and your slab, you've already let it dry too far. Close that gap gradually — don't blast it with water, which causes its own problems.
- Mind your big trees. Mature oaks (one of the things we love about communities like Greatwood and First Colony) drink enormous amounts of water and can pull moisture out from under a foundation. Trees within 15–20 feet of the slab make consistent watering even more important.
Do this one thing and you've protected the most valuable structural component of your home for the price of a soaker hose and a hose timer.
Get Your AC Ahead of the Heat, Not Behind It
Your air conditioner is about to run a marathon. The worst time to discover it can't finish is the first 102° afternoon, when every HVAC company in Fort Bend County has a three-day wait and an emergency-rate price sheet.
Do this now:
- Change the filter — then change it again on schedule. During peak summer, a dirty filter chokes airflow, spikes your bill, and overworks the system. Check monthly.
- Hose off the outdoor condenser. Cut the power first, then gently wash the fins clear of grass clippings, pollen, and dust. A clogged condenser can't dump heat, and a unit that can't dump heat dies in July.
- Book a tune-up before the rush. A technician checks refrigerant charge, capacitors, and the coil. Capacitors are the part that fails first in extreme heat — a $20 part that takes out your whole system on the hottest day if it's marginal.
- Clear the condensate drain line. Clogged drain lines back up and overflow, and in our humidity that means water damage and mold. Pour a little distilled vinegar through the line.
- Know your system's age. If your AC is 12–15+ years old, this is the summer to budget for replacement on your terms — not in a panic mid-July when it quits.
If your home is older and you've never had the ductwork or attic insulation evaluated, a sustained-heat summer is when leaky ducts and thin insulation cost you the most.
Cut Your Electric Bill Against a Record-Demand Grid
With ERCOT forecasting record demand, electricity is the summer expense that surprises people. A few moves meaningfully lower the bill without making your house uncomfortable.
Pre-cool before the evening crunch. Remember that 8–9 p.m. grid-strain window. If you're on a time-of-use plan, let your house cool hard in the late afternoon and ease back in the early evening — you ride out the peak on a house that's already cold instead of fighting the heat at the worst hour. Even on a flat-rate plan, a programmable or smart thermostat that nudges the setpoint a couple degrees during peak hours adds up over ten weeks.
Shade the west side. Afternoon sun on west-facing windows is a heat freight train. Cellular shades, exterior solar screens, or even strategically placed landscaping cut the load your AC has to fight.
Seal the cheap leaks. Weatherstrip doors, caulk around windows, and check that attic access hatch — hot attic air pouring into your living space is invisible money. Sugar Land attics hit 130°+; you do not want that air migrating down.
Ceiling fans, used correctly. Fans cool people, not rooms. Run them when you're in the room and turn them off when you leave — and make sure they're spinning counterclockwise (pushing air down) for summer.
Review your retail electricity plan. Texas is deregulated; you can shop your provider. If your fixed-rate contract is expiring this summer, don't let it roll to a punishing variable rate right as demand peaks.
Don't Forget the Outside of the House
The heat works on your home's exterior too, and these are the items that quietly turn into bigger problems.
- Roof and attic ventilation. Heat trapped in a poorly ventilated attic shortens roof life and bakes your second floor. If your upstairs is always 5–8 degrees hotter, ventilation is often the culprit.
- Reseal exterior wood. Decks, fences, and door frames dry out and split in the sun. A summer reseal extends their life by years.
- Irrigation efficiency. Water in the early morning, not midday (when most of it evaporates) or at night (which invites fungus in our humidity). A smart controller pays for itself.
- Pool maintenance. In extreme heat, pool water evaporates fast and chemistry swings hard. Check levels more often, and keep an eye on the pump — it's working overtime too.
- Gutters and drainage. Summer storms in Houston arrive violent and sudden. Clear gutters now so the first downpour doesn't dump water against the foundation you just spent the season protecting.
A Quick June Walkthrough Checklist
If you do nothing else, do these, roughly in order of money-at-stake:
- Set up foundation watering (soaker hoses + timer)
- Change the AC filter and hose off the condenser
- Book an HVAC tune-up before the rush
- Clear the condensate drain line
- Shade or screen west-facing windows
- Seal door/window/attic-hatch leaks
- Review your electricity plan and thermostat schedule
- Clear gutters before the first big storm
None of this is glamorous. All of it is cheaper than the repair it prevents.
Why This Matters Beyond Comfort
Here's the part that ties back to what I actually do for a living. The condition of your home in summer isn't just about getting through August — it's about protecting the asset.
Foundation issues, an aging AC, deferred roof maintenance — these are exactly the things that surface during a buyer's inspection and knock thousands off your sale price, or kill a deal outright. The homeowners who stay ahead of Texas summers don't just live more comfortably; they protect their equity. When it's eventually time to sell, their home inspects clean and shows well.
If you're thinking about selling in the next year or two, a summer maintenance pass is one of the highest-return things you can do. And if you want a straight read on what's actually worth fixing for resale versus what buyers won't care about, that's exactly the kind of walkthrough I do for clients.
Whether you're settling into your first Sugar Land summer, and my moving to Sugar Land guide covers the rest of the adjustment, or you've weathered twenty of them, the house always tells the truth in July. Get ahead of it now.
