Signs You Need Air Conditioning Repair

You’ll know that your home’s air conditioner needs repairs if you notice:

  • Frost on the outdoor unit: When you see ice on your AC, it could be caused by a dirty air filter, low refrigerant, or dirty evaporator coils.
  • Strange noises: If you hear buzzing, grinding, or any other abnormal sound from your unit, there might be loose parts, refrigerant leaks, or a faulty compressor.
  • Inconsistent airflow: Weak airflow leads to hot and cold spots around your home. If replacing your filter doesn’t resolve the problem, you need an HVAC technician.
  • Strange odors: Musty smells mean you’re overdue for maintenance and could have mold or bacteria buildup in your AC, causing dirty filters, drain pans, or ductwork. Call a professional immediately if you smell burning odors because it’s likely frayed wiring, an overheated motor, or another electrical hazard.
  • Increased cooling costs: Steadily increasing energy bills without much change in usage is a sign that there’s a hidden AC malfunction. You could also be overdue for maintenance or an old system that needs to be replaced.
  • Thermostat malfunctions: Your thermostat is the brain of your HVAC system. If it has no power or is unresponsive, you won’t have the air conditioning you need.

Have you noticed any of these signs? Call Len The Plumber Heating & Air at (800) 950-4619(800) 950-4619 to schedule AC repair for your Montgomery, Bucks, Chester, Delaware, and New Castle County home. 

Should I Repair or Replace My Air Conditioner?

At Len The Plumber Heating & Air, we know many homeowners worry that an AC breakdown may result in a system replacement.

Upgrading to a new air conditioner is a big investment, so we’d only recommend an AC replacement if it was the most efficient and cost-effective option.

Air conditioning repair is often possible as long as your system is still under warranty and needs relatively minor repairs.

Units over 10 years old that need frequent service are often better candidates for replacement.

Request air conditioning service online or call (800) 950-4619(800) 950-4619 now. Len The Plumber Heating & Air’s team of skilled technicians can help you decide whether repair or replacement is best.

Frequently Asked Questions

How can you prevent AC breakdowns?

Many AC breakdowns can be prevented by scheduling at least one routine air conditioning maintenance appointment each year.

Professional AC maintenance slows down normal wear and tear, extending your unit’s service life and ensuring it operates efficiently.

How do you reset your air conditioner?

Flip your AC’s circuit breaker so you know it’s completely powered down.

Then, look for a small red button on your unit. If you’re having trouble finding the reset button, try looking in your air conditioner’s manual.

Press and hold the button for three to five seconds to reset the system. Afterward, you can flip the breaker back on and run a test cycle to ensure proper airflow.

How do you defrost an air conditioner?

Change your thermostat setting from “cool” to “off” and the fan setting from “auto” to “on.”

The fan will blow warm air over the frozen coils. After a few hours, all the ice should melt.

After that, your HVAC technician needs to inspect your unit to determine the cause and appropriate repair.
