Garland's older homes show AC trouble in predictable ways. Here are the six warning signs worth acting on early, and what each repair typically costs.
Garland’s housing stock leans older — a lot of homes here were built in the 60s, 70s, and 80s, and original or first-replacement systems are now well past the age where minor issues turn into major ones. The trick isn’t waiting for total failure. It’s catching the warning signs early, when a fix is still a $200 repair instead of a $2,000 one.
Your energy bill jumped without a clear reason. A system working harder than it should — due to a refrigerant leak, dirty coil, or failing motor — shows up on the electric bill before it shows up as a total breakdown.
Cooling takes longer than it used to. If your house used to hit its set temperature in 20 minutes and now takes an hour, something’s already reducing efficiency.
Short cycling. The system turns on, runs for a few minutes, and shuts off repeatedly. This is hard on components and often points to electrical issues, a refrigerant problem, or a failing thermostat.
Odd smells. A musty smell usually means mold or moisture in the ductwork or coil. A burning smell is more serious — that warrants an immediate call, not a wait-and-see approach.
Uneven cooling room to room. Sometimes this is ductwork, sometimes it’s a failing component restricting airflow. Either way, it’s worth diagnosing rather than just closing vents to compensate.
Ice on the refrigerant lines. Counterintuitively, ice usually means low refrigerant or restricted airflow, not that the system is working “too well.”
| Issue | Likely Cause | Cost Range |
|---|---|---|
| Rising energy bills | Dirty coil, leak, failing motor | $150 – $600 |
| Short cycling | Thermostat, capacitor, refrigerant | $150 – $500 |
| Ice on lines | Low refrigerant, airflow restriction | $250 – $1,200 |
| Uneven cooling | Ductwork, failing blower | $200 – $800 |
