Why Your AC Isn’t Keeping Up in the Lubbock Heat
When the Lubbock heat hits 100°, your air conditioner should keep you cool — not leave you sweating on the couch. But every summer, we get the same calls:
“My AC’s running all day, but the house is still hot.”
If that sounds like you, here’s why it’s happening — and what to do about it.
🌡 1. It’s Too Hot for a Weak System
Older or undersized AC systems simply can’t handle the brutal Texas heat. Most units are designed for 95° outdoor temps, and Lubbock regularly hits well over that.
If your system’s struggling during peak heat, it could be:
Too small for your home
Losing efficiency
Near the end of its lifespan
🧱 2. Your Insulation Sucks
If your attic or walls aren’t properly insulated, the cool air escapes — and your AC keeps running nonstop.
Signs of poor insulation:
One or two rooms always hotter than the rest
High energy bills with no change in use
AC feels “weak” even though it’s blowing air
🌬 3. Dirty Coils or Filters
Dust storms, cotton, and West Texas wind mean your system clogs up fast. Dirty coils and filters kill airflow and cooling power.
If it’s been more than 30–60 days since you changed your filter, do it now.
🛠 4. Your System Needs a Tune-Up
If your unit hasn’t been serviced this year, it’s running inefficiently — maybe dangerously.
A full system tune-up can:
Restore airflow
Lower your electric bill
Prevent surprise breakdowns in the middle of July
🔁 5. It’s Just Time for a New System
If your AC is 12+ years old, has been repaired multiple times, and still can’t cool the house — it’s time to replace it. Today’s high-efficiency systems work better, run quieter, and cost less to operate.
