Preventative maintenance for the Rio Grande Valley climate

Generic maintenance advice is written for a generic climate. The Valley is not one.

Air conditioning is not a comfort system here

In a Valley summer, a failed air conditioner is a habitability problem and a resident-retention problem on the same day. It is also the most expensive predictable failure in the portfolio.

• Service the system in spring, before the first genuinely hot week
• Replace filters on a schedule and make it easy for the resident to do so
• Keep the condenser clear and the coils clean
• Check the condensate drain line — a blocked line causes water damage that costs far more than the visit
• Know the age of every system you own; a fifteen-year-old unit is a budgeting item, not a surprise

Hard water is a real cost line

Valley water is hard, and it shortens the life of water heaters, fixtures and appliances.

• Flush water heaters annually
• Expect shorter fixture and cartridge life than manufacturer averages suggest
• Consider treatment where the same property keeps producing plumbing calls

Freeze events

Rare, and expensive when they arrive. A single burst pipe outruns a decade of preventative maintenance spending.

• Know where the main shut-off is on every property, and make sure the resident does too
• Insulate exposed pipes and outdoor spigots
• Send residents freeze guidance before the forecast, not during it
• Keep a shut-off instruction in the resident's portal so it is findable at 2am

Sun and wind

• Exterior paint and caulking degrade faster than in milder climates
• Roofs take sustained UV and occasional high wind; look after storms
• Fences and gates loosen; a loose gate becomes a lost pet and an unhappy resident

The economics

Preventative maintenance always looks like an unnecessary expense until the year it isn't. A $120 spring air-conditioning service against a $4,500 replacement is not a difficult trade — but only if someone is actually scheduling it.

That is what routine inspections are for. Not to catch residents doing something wrong, but to find the small thing while it is still small.
