A new year is a great time to reset – not just your calendar, but your home, too.

In San Antonio, home maintenance looks a little different than it does in other parts of the country. Between heat, sudden temperature swings, expansive clay soil, storms, and year-round pests, staying ahead of small issues can save homeowners thousands over time.

This New Year home maintenance checklist focuses on the systems that matter most for San Antonio homes, with quick explanations so you know why each task is worth your time.

HVAC System: Start the Year Efficiently

✔ Replace air filters
Clean filters improve airflow, indoor air quality, and system efficiency – especially important as cedar pollen season ramps up. (It typically peaks in mid-January in San Antonio, and can last through early March)

✔ Schedule a professional HVAC tune-up
San Antonio homes rely heavily on AC. Catching wear and tear early helps prevent mid-summer breakdowns when service calls are expensive and availability is limited.

✔ Check thermostat settings
Make sure your system isn’t working harder than necessary during mild winter weather.

Why this matters locally:
Long cooling seasons mean HVAC systems here in San Antonio experience more strain than in many other areas.

---

Roof, Gutters, and Attic

✔ Inspect the roof (or have it inspected)
Look for missing shingles, flashing issues, or signs of wear after storms.

✔ Clean gutters and downspouts
Clear debris so water flows away from the home properly.

✔ Check attic ventilation and insulation
Proper airflow helps regulate indoor temperatures and protects roofing materials.

Why this matters locally:
Sudden storms and heavy rain can expose weak points quickly, and drainage issues can affect both roofs and foundations.

---

Foundation and Drainage (Big One for San Antonio)

✔ Walk the perimeter of your home
Look for standing water, soil pulling away from the foundation, or areas where water pools after rain.

• If you notice soil pulling away from the foundation: this is often a sign that the soil has dried out and shrunk — something that’s very common with San Antonio’s expansive clay soil. Refill the gap with soil so it’s flush against the foundation, lightly compact it, and aim to keep moisture around the home consistent during dry periods. The goal isn’t to soak the soil, but to avoid extreme dry-to-wet cycles over time.
• If you notice water pooling near the foundation after rain: start by checking that gutters are clear and downspouts are directing water several feet away from the home. In some cases, extending downspouts or adjusting soil grading so it slopes gently away from the house can make a big difference. If pooling continues, it may be worth consulting a drainage professional to explore longer-term solutions.

✔ Confirm downspouts drain away from the home
Water should be directed several feet away from the foundation to reduce soil saturation next to the slab.

✔ Monitor interior cracks
Small hairline cracks can be normal, but new cracks or cracks that appear to widen over time are worth keeping an eye on.

Why this matters locally:
San Antonio’s expansive clay soil expands and contracts with moisture changes, which means foundation health is closely tied to how water moves around your home. Consistent drainage and moisture management can help prevent unnecessary movement and larger issues down the road.

Plumbing and Water Systems

✔ Check for leaks under sinks and around toilets
Even small leaks can lead to higher bills and hidden damage.

✔ Inspect hose bibs and outdoor faucets
Occasional freezes can still happen, and damaged fixtures are easy to miss.

✔ Flush the water heater (if recommended by manufacturer)
This helps remove sediment and improve efficiency.

✔ Check and maintain your water softener (if you have one)
Water softeners are very common in San Antonio due to the mineral content of the local water supply.

• Check salt levels and refill as needed
• Make sure the system is cycling properly
• Review manufacturer maintenance recommendations

A well-maintained water softener can help reduce scale buildup in plumbing fixtures, water heaters, and appliances over time.

Why this matters locally:
San Antonio’s mineral-heavy water can contribute to scale buildup and wear on plumbing systems. Routine checks — especially for water heaters and softeners — can help prevent premature repairs and extend the life of your home’s systems.

---

Exterior and Landscaping

✔ Trim plants and foliage away from the house
Keep shrubs, vines, and tree limbs from touching siding, rooflines, windows, and the foundation.

Trimming back vegetation helps:

• Deter pests, including wood-destroying insects
• Prevent moisture from being trapped against the home
• Reduce wear on exterior surfaces from constant contact

Larger tree limbs should also be monitored closely. Branches rubbing against the home can damage siding and roofing materials over time, and during storms, overhanging limbs can be knocked into the house.

✔ Check fences, decks, and exterior wood
Look for signs of rot, wood-to-ground contact, or areas where moisture tends to collect.

✔ Refresh mulch in landscaping beds
Adding or replacing mulch helps regulate soil temperature and retain moisture. During colder weather, mulch can also provide a layer of protection for plants during hard freezes.

✔ Review irrigation settings
Adjust watering schedules seasonally to avoid overwatering near the foundation while still keeping landscaping healthy.

Why this matters locally:
San Antonio’s warm climate supports year-round plant growth, but that growth can quickly become a maintenance issue if it’s not managed. Thoughtful landscaping helps protect both your home and the systems around it.

Interior Safety and Systems

✔ Test smoke and carbon monoxide detectors
Replace batteries annually – the New Year is an easy reminder.

✔ Check caulking and seals around windows and doors
This helps with energy efficiency and moisture control.

✔ Review electrical outlets and breakers
Take note of loose outlets, warm outlets or switches, flickering lights, or breakers that trip repeatedly.

• If you have loose outlets:
  Loose outlets can be a sign of worn connections behind the wall. This isn’t something to ignore, as loose wiring can create heat and increase fire risk. The safest next step is to have a licensed electrician evaluate and secure the connection rather than trying to tighten it yourself.
• If breakers trip frequently:
  Occasional tripping can happen, especially if multiple high-draw appliances are running at the same time. However, a breaker that trips more than once or twice in a short period, trips without a clear cause, or needs to be reset regularly is worth investigating. This can indicate:
  • An overloaded circuit
  • A faulty appliance
  • Aging wiring or breaker issues

In these cases, it’s best to have an electrician assess the situation to identify the cause and recommend a safe solution.

Why this matters locally:
Many San Antonio homes – especially those built during periods of rapid growth – may have electrical systems that weren’t designed for today’s appliance and technology usage. Addressing small electrical issues early can help prevent larger problems later.

What to Tackle Now vs. Throughout the Year

Best to handle early in the year:

• HVAC servicing
• Drainage and foundation checks
• Roof and gutter inspections

Can be spaced out:

• Interior caulking and minor repairs
• Landscaping adjustments
• Cosmetic touch-ups

Breaking maintenance into manageable chunks makes it far more likely it actually gets done.
