In the property management business, August is not the time to discover your air conditioning unit is low on refrigerant, nor is July the time to learn that a slow-draining sink has finally backed up completely. When the Texas summer hits its peak, contractors are booked weeks in advance, and emergency service calls come with a premium price tag.
The proactive landlord understands that the most expensive repair is an emergency repair. By conducting methodical AC and plumbing checks in the spring, before the heavy usage period begins, you can identify and resolve minor issues before they escalate into major, costly failures. Here is your checklist for securing your property’s most critical lifelines.
The HVAC System: Your Summer Priority
If an AC unit is going to fail, it will almost certainly happen when it is working its hardest—typically on a 100-degree afternoon. A failing AC is not just a maintenance issue; it is a tenant retention issue. No one wants to renew a lease on a property that couldn’t keep them cool in August.
The Visual Inspection and Filter Check
Begin your HVAC check at the indoor air handler. The very first step is the simplest: check the air filter. A clogged filter restricts airflow, forcing the system to work harder, which increases energy consumption and drastically shortens the lifespan of the compressor. If the filter is dirty, replace it immediately. More importantly, use this opportunity to remind your tenant of their lease obligation to replace the filter every 30 to 60 days.
Next, inspect the condensate drain line. In the humid Texas climate, these lines frequently become clogged with algae, causing water to back up and overflow the drain pan, which can lead to severe ceiling or floor damage. Pouring a cup of white vinegar down the drain line every spring is an inexpensive, highly effective preventative measure to keep the line clear.
The Outdoor Condenser Unit
Move outside to the condenser unit. The coils on this unit need to breathe to dissipate heat effectively. Inspect the perimeter of the unit and clear away any leaves, debris, or overgrown vegetation. There should be a minimum of two feet of clearance around the entire unit.
While you can visually inspect the exterior, the internal components require professional attention. We strongly recommend scheduling a licensed HVAC technician for a comprehensive spring tune-up. They will clean the condenser coils, check the refrigerant levels, inspect the electrical connections, and verify the amperage draw on the compressor. A system that is slightly low on refrigerant might still cool the house in May, but it will freeze over and fail entirely in July. Catching that deficiency now is the essence of preventative maintenance.
Plumbing: Stopping Leaks Before They Start
While the HVAC system is the star of the summer, the plumbing system is the silent workhorse. Increased occupancy and usage during the summer months mean your plumbing will be under greater stress.
The Under-Sink Inspection
Grab your flashlight and systematically check under every sink in the property. You are not just looking for active drips; you are looking for evidence of past or intermittent leaks. Look for warped cabinet bottoms, water stains on the wood, or a musty smell.
Run the water in each sink and watch the P-trap (the curved pipe beneath the drain). Run your hand along the pipes to feel for moisture. While the water is running, observe how quickly the sink drains. A slow drain now will become a clogged drain when guests arrive for a summer barbecue. If a drain is slow, clear the trap or snake the line before the tenant calls it in as an emergency.
Toilets and Water Heaters
Toilets are notorious for silent leaks that can add hundreds of dollars to a water bill over a summer. Remove the tank lid and inspect the flapper valve. If it looks warped or degraded, replace it—it is a five-dollar part that takes two minutes to install. Add a few drops of food coloring to the tank water and wait fifteen minutes without flushing. If the color seeps into the bowl, the flapper is leaking and must be replaced.
Finally, inspect the water heater. Look for any signs of rust, corrosion, or pooling water around the base of the tank. A failing water heater rarely gives a dramatic warning; the signs are usually subtle and visible long before the tank bursts.
The Bottom Line
Preventative maintenance is not glamorous, but it is profitable. The hour you spend inspecting your AC and plumbing systems in the spring will pay dividends in August. By identifying minor issues early, you avoid the premium costs of emergency repairs and ensure your tenants remain comfortable throughout the grueling Texas summer.
