When temperatures in Oklahoma start climbing, homeowners rely heavily on one system to stay cool: the air conditioner. But during a home inspection, simply turning on the AC isn't the only action we take.

At D1 Home Inspections, we dig deeper. Whether you’re a first-time buyer, a seasoned homeowner, or a realtor assisting clients, understanding how AC inspections work can save you from unexpected repairs. It also ensures that your real estate transaction flows more smoothly.

Types of AC Systems We Inspect

In the Oklahoma City area, we typically encounter the following systems:

Central Split Systems: This includes an outdoor condenser and an indoor evaporator.
Packaged Units: Commonly found in older homes and rural areas.
Ductless Mini-Split Systems: Often used in additions or garages.
Heat Pumps: These systems operate in cooling mode and are prevalent in newer constructions.

Each type requires specific inspection points. However, our goal remains constant: To check what’s accessible, functional, and safe.

Key Aspects of an AC Inspection

You might think, "If it turns on, it's good to go." However, there’s much more involved in a thorough inspection. Here’s what we examine:

Thermostat Response: We check if the system turns on conveniently when adjusted.
Cooling Mode Operation: We ensure it is safe to run the unit. (Note: We avoid running it under 65°F.)
Temperature Differential: Measuring the temperature difference between the return and supply vents is essential. Ideally, it should range between 14–22°F.
Refrigerant Line Condition: We assess whether insulation is intact and if there's any sign of leakage.
Outdoor Condenser Unit: The fins should be clean, unobstructed, level, and secure.
Condensate Drain Line: We check if it is sloped correctly, clean, and flowing. Clogs can lead to flooding in your attic or closet.
System Age: If accessible, we note the manufacture date and outline lifespan expectations. Typically, systems last 12–15 years.

Why AC Issues Are Crucial for Oklahoma Homes

Oklahoma's weather shifts rapidly. Systems often remain unused for months and then operate non-stop during weeks with temperatures exceeding 90°F. This fluctuation creates multiple problems, such as:

Clogged Drain Lines: Inactivity can lead to clogs.
Damaged Insulation: UV exposure can deteriorate insulation.
Crushed Fins: Caused by weed trimming or debris accumulation.
Improper Installations: Common in flip houses or during quick remodels.

We inspect for these issues because they can lead to system failures when you need it most.

The Impact of AC Inspections on Real Estate Transactions

For realtors, inspections should not jeopardize deals; instead, they should clarify risks. When we explain that a "working" AC might have a clogged drain or damaged lines, we’re not trying to alarm buyers. We’re helping all parties plan for the future.

This kind of transparency establishes trust with clients and prevents unexpected issues after closing.

Practical Tips for Buyers and Homeowners

Change Filters: Replace them every 1–3 months, especially in dusty rural areas.
Avoid Running AC Below 65°F: Protect the system from damage.
Schedule Professional Servicing: Have your system serviced before the start of summer.
Ask About the System’s History: Inquire about age and maintenance history during your inspection.

Final Thoughts: Be Informed Before the Heat Hits

An AC unit might "kick on," but that doesn’t mean it’s prepared for the scorching Oklahoma summer. Our role isn’t to scare; it’s to inform you adequately.

A comprehensive AC inspection highlights what is functioning, what is aging, and what needs attention. That peace of mind is worth every degree, especially during the hot months.
