Warning Signs

Signs your air conditioner needs attention

Your AC usually gives you warning signs before it quits. Call us if you notice any of these. Catching them early often means a smaller, cheaper repair and helps your system last longer.

Warm air from the vents

Air blowing warm when it should be cold, even with cooling on.

Weak or uneven airflow

Poor airflow throughout the home, or some rooms never cooling.

Strange noises

Rattling, grinding, squealing, or hissing coming from the unit.

Not cooling properly

The home stays warm even with the thermostat set low.

Rising energy bills

Cooling costs climbing with no change in how you use the system.

Ice on the unit

Ice forming on the coil or refrigerant lines, a sign of trouble.

Water leaks

Water pooling or leaking around the indoor unit.

Running constantly

The system runs non-stop without ever reaching the set temperature.

Repair or Replace

Repair or replace your AC?

Not sure whether to fix or replace? A good rule of thumb.

Repair

makes sense when the unit is relatively young, the issue is isolated, and it still cools efficiently.

Replacement

is often the smarter long-term choice when an AC is aging, needs frequent repairs, or your energy bills keep climbing. A modern high-SEER unit can pay for itself in efficiency over time.

Our technicians give you an honest recommendation based on what is best for your home, not what is most expensive.

FAQ

Air conditioning questions, answered

Why is my AC running but not cooling?

Common causes include a dirty air filter, low refrigerant, a clogged or blocked outdoor coil, a faulty blower motor, or thermostat issues. Some are quick fixes, so it is worth having a technician diagnose it before the problem gets worse.

What are the signs my air conditioner needs repair?

Watch for warm air from the vents, weak airflow, strange noises, rising energy bills, ice on the refrigerant lines, water leaks, and a system that runs non-stop without cooling.

How long does a home air conditioner last?

With regular maintenance, a well-installed central AC system typically lasts around 12 to 15 years. Routine servicing helps extend its life and keeps efficiency high.

What does SEER mean and why does it matter?

SEER stands for Seasonal Energy Efficiency Ratio. A higher SEER rating means the system uses less energy to cool your home, which can lower your summer energy bills. We install high-SEER Armstrong Air units for exactly this reason.

Should I repair or replace my AC?

If your unit is relatively young and the issue is isolated, repair is usually the best value. For older systems with frequent breakdowns or high energy bills, a new high-SEER unit often saves more over time. We will give you an honest recommendation.
