March Maintenance: Prepping for the Texas "Triple Threat"

The Texas "Triple Threat" — and Why March Matters

If you own a home in Texas, you already know: summer doesn't politely knock. It kicks down the door sometime around late May and doesn't leave until October. And it brings three forces that will test every system in your home — humidity, heat, and hail.

Humidity breeds mold in attics and crawl spaces, warps door frames, and makes your AC work overtime. Heat pushes your HVAC to its absolute limit for months on end. And the spring thunderstorm season — which ramps up in April and May — can drop baseball-sized hail on a roof that wasn't ready for it.

March is the sweet spot. The brutal summer hasn't arrived yet, contractors aren't fully booked, and you still have time to address problems before they become emergencies. Every dollar you spend on prevention in March saves five or more in emergency repairs come July. Here are the five things every Texas homeowner should do this month.

1. HVAC Tune-Up: Beat the May Rush

Your air conditioner is about to run 12-16 hours a day for the next five months. In parts of Austin, Dallas, and Houston, it may not shut off at all during peak July and August heat. An HVAC system that hasn't been serviced is like driving cross-country without an oil change — it might make it, but the odds aren't in your favor.

A standard March tune-up costs $75-$150 per unit. The technician will check refrigerant levels, clean the evaporator and condenser coils, inspect the blower motor, test the thermostat calibration, and verify that the drainage line is clear. That last one matters more than you think — a clogged condensate drain is the #1 cause of HVAC-related water damage in Texas homes.

Here's the real reason to book in March: by May, every HVAC company in the state is slammed. Wait times stretch from days to weeks, and emergency calls on 100-degree weekends can cost $300-$500 just for the service visit — before any parts. A March tune-up also extends the life of your system. The average AC unit in Texas lasts 10-12 years (compared to 15-20 in cooler climates), but well-maintained systems regularly hit 15.

What to do right now: Call your HVAC company and book a tune-up for this month. Replace your air filter (you should be doing this every 30-60 days in Texas, not quarterly). If your system is over 10 years old, ask the technician for an honest assessment of its remaining life so you can plan a replacement on your timeline — not during a heat emergency.

2. Roof & Gutter Check: Preparing for Spring Storms

Texas spring thunderstorm season is no joke. Between April and June, powerful supercell storms roll through the DFW Metroplex, Central Texas, and the San Antonio corridor with regularity. These storms bring damaging hail, high winds, and torrential rain — and your roof is the first line of defense.

A March roof inspection catches problems while they're still small. Missing or curling shingles, cracked flashing around vents and chimneys, and deteriorated sealant around skylights are all issues that a $200-$400 repair can fix today but that could lead to $3,000-$8,000 in water damage if a spring storm exploits them.

Don't forget the gutters. Texas live oaks shed leaves in March (yes, they're "evergreen" but they drop their old leaves as new ones come in). Clogged gutters during a heavy spring rain don't just overflow — they direct water toward your foundation, compounding the exact problem we'll address next. Clean your gutters, check that downspouts extend at least 4-6 feet from the foundation, and verify that splash blocks are directing water away from the house.

What to do right now: Walk your property and look up. Note any visible shingle damage, sagging gutters, or debris buildup. Most roofing companies offer free inspections — take them up on it. If your roof is over 15 years old or took hail damage in a previous season, a professional inspection is non-negotiable. Keep in mind that if you do find storm damage later, a documented pre-storm inspection strengthens your insurance claim.

3. Foundation Hydration: Yes, You Water Your House

If you're new to Texas homeownership, this one sounds absurd. But ask any structural engineer in the state and they'll tell you the same thing: watering your foundation is one of the most important things you can do to protect your home.

Here's why. Most of Texas sits on expansive clay soil — the black, sticky stuff that civil engineers call "vertisol." This soil expands dramatically when wet and shrinks when dry. During hot, dry months, the soil pulls away from your foundation, creating gaps. The slab shifts. Cracks appear in walls, doors stick, floors become uneven. Foundation repair in Texas averages $5,000-$15,000, and severe cases can exceed $30,000.

The goal is to maintain consistent moisture levels around your foundation year-round. In March, the soil still has some moisture from winter rains, making it the perfect time to establish your watering routine before the ground dries out in summer. Use a soaker hose placed 12-18 inches from the foundation, running it for 15-20 minutes per zone, 2-3 times per week. Increase frequency as temperatures rise and rainfall drops.

Watch for warning signs: cracks in exterior brick (especially stair-step patterns in mortar joints), doors or windows that suddenly stick or won't close properly, gaps between the wall and ceiling or floor, and visible gaps between the soil and the foundation perimeter. If you see any of these, a foundation inspection ($300-$500) is a worthwhile investment.

What to do right now: Buy a soaker hose and lay it around your foundation perimeter. Set a watering schedule — many homeowners tie it to their sprinkler system timer. If you already have foundation concerns, schedule an inspection with a structural engineer (not just a foundation repair company, which has an inherent conflict of interest).

4. Pest Barrier: Termites and Ants Wake Up in March

March soil temperatures in Texas hover in the mid-60s to low-70s — exactly the range where subterranean termites begin their annual swarming. You might see small winged insects near windows, doors, or in your garage. Those are termite swarmers looking for new nesting sites, and your home is on the menu.

Subterranean termites cause more structural damage in Texas than storms, fires, and floods combined. They can silently eat through structural wood for years before you notice, and the average cost of termite damage repair runs $3,000-$8,000. Many homeowner insurance policies do not cover termite damage because it's considered a maintenance issue — making prevention all the more critical.

Fire ants also ramp up activity in March. While they're more of a nuisance than a structural threat, their mounds near your foundation can undermine soil stability and create entry points for water. Carpenter ants, on the other hand, do cause structural damage by hollowing out wood for nesting — and they're common in the wooded neighborhoods of Austin, The Woodlands, and East Texas.

What to do right now: Walk your home's perimeter and seal any visible cracks or gaps in the foundation, around pipes, and where utilities enter the house. Use silicone caulk for small gaps and expandable foam for larger ones. Ensure wood mulch is at least 12 inches from the foundation (termites love mulch as a bridge to your home). Consider a professional pest inspection — many companies offer free termite inspections. If you haven't had a termite treatment in the past five years, now is the time.

5. Bonus: Weatherstripping & Insulation Check

This one doesn't get the dramatic headlines, but it directly impacts your summer energy bill — which in Texas can easily run $250-$400/month during peak cooling season. Worn weatherstripping around doors and windows lets conditioned air escape and hot, humid air seep in, forcing your AC to work harder and longer.

Check every exterior door by closing it on a piece of paper. If the paper slides out easily, the seal isn't tight enough. Inspect weatherstripping around the garage door, too — many Texas homes have HVAC equipment or ductwork in the garage, and a poorly sealed garage door lets attic-level heat into the space.

While you're thinking about insulation, March is a comfortable time to check your attic. Texas building codes call for R-38 insulation (about 12-14 inches of blown fiberglass or cellulose), but many older homes have R-19 or less. Upgrading attic insulation costs $1,500-$3,000 for a typical home and can reduce summer cooling costs by 15-25%. Some Texas utility companies offer rebates for insulation upgrades.

What to do right now: Replace worn weatherstripping on all exterior doors ($20-$50 per door in materials). Check attic insulation depth — if you can see the tops of the ceiling joists, you need more. Inspect window caulking and reseal any cracked or missing sections.

DIY vs. Calling a Pro

Not everything on this list requires a professional. Here's a quick breakdown:

Total cost if you handle the DIY items yourself and hire pros for the rest: roughly $250-$600. Total potential savings from preventing summer emergencies: $5,000-$15,000+. That's a return on investment that would make any financial advisor jealous.

Your March Maintenance Calendar

Here's a week-by-week schedule to make this manageable:

Week 1 (March 1-7): Call and schedule your HVAC tune-up. Replace air filters. Order soaker hoses if you don't have them.

Week 2 (March 8-14): Walk the property. Inspect the roof from ground level, clean gutters, check downspout extensions. Seal visible cracks in the foundation perimeter.

Week 3 (March 15-21): Install soaker hoses and begin your foundation watering schedule. Inspect and replace weatherstripping on exterior doors. Check attic insulation.

Week 4 (March 22-31): Schedule a termite inspection if you haven't had one recently. Pull mulch back from the foundation. Treat fire ant mounds. Do a final walk-around to catch anything you missed.

By April 1, you'll have a home that's genuinely prepared for whatever Texas throws at it this summer. And when your neighbor is scrambling to find an HVAC tech on a 107-degree Saturday in July, you'll be sitting comfortably at 72 degrees knowing your system was ready for this months ago.

Frequently Asked Questions

Why do I need to water my foundation in Texas? +

Texas soil — especially the black clay (vertisol) found across much of Central and North Texas — expands when wet and shrinks when dry. During hot, dry months, the soil pulls away from your foundation, creating gaps that allow the slab to shift and crack. Consistent moisture around your foundation prevents this cycle and can save you $5,000-$15,000 or more in structural repairs.

How much does an HVAC tune-up cost in Texas? +

A standard HVAC tune-up in Texas costs $75-$150 per unit when booked in March or April. Waiting until May or June often means higher prices ($150-$250) due to peak season demand, plus longer wait times for appointments. Many companies offer spring specials or maintenance plan discounts that bring the cost even lower.

When is termite season in Texas? +

Termite swarm season in Texas typically runs from March through May, with peak activity in April. Subterranean termites — the most common and destructive type in Texas — begin swarming when soil temperatures reach the mid-70s. March is the ideal time to inspect for signs of activity and seal entry points before colonies become fully active.

How often should I have my roof inspected in Texas? +

Texas homeowners should have their roof professionally inspected at least once per year, ideally in March before spring storm season. Additional inspections are recommended after any major hail event or severe storm. Most roofing companies offer free inspections, and catching small issues early can prevent leaks that lead to thousands in interior water damage.
