Question 1

Why is my AC running but not cooling?

Accepted Answer

The system may be low on refrigerant, have a dirty coil, a failing compressor, or a problem with the blower or airflow. A technician can test pressures, temperatures, and airflow to isolate the cause.

Question 2

How often should I change my AC filter?

Accepted Answer

In South Florida, check the filter monthly and replace it when it looks dirty. Homes with pets, high dust, or constant AC use may need more frequent changes. A clogged filter reduces airflow and can freeze the coil.

Question 3

What temperature should I set my thermostat in summer?

Accepted Answer

Most homeowners are comfortable between 74 and 78 degrees. The lower you set it, the more the system runs and the higher your bill. A programmable or smart thermostat can help reduce runtime when you are away.

Question 4

Why does my AC keep freezing up?

Accepted Answer

Ice on the coil is usually caused by low refrigerant, restricted airflow from a dirty filter or blocked vents, or a failing blower. Turn the system off and call for service — running it frozen can damage the compressor.

Question 5

How long should a central AC unit last?

Accepted Answer

In South Florida, a well-maintained central AC unit typically lasts 10 to 15 years. Coastal exposure, heavy use, and skipped maintenance can shorten that. Ductless mini-splits and heat pumps have similar lifespans with proper care.

Question 6

Is a bigger AC unit better?

Accepted Answer

No. An oversized unit short-cycles, which reduces efficiency, increases humidity, and wears components faster. The right size is based on a load calculation, not just the square footage of the home.

Question 7

What is SEER and why does it matter?

Accepted Answer

SEER measures cooling efficiency. A higher SEER rating means the system uses less electricity, but it also costs more upfront. In South Florida, efficiency matters because the system runs so many hours per year.

Question 8

Should I repair or replace my AC?

Accepted Answer

Consider replacement if the compressor has failed, the system is old and inefficient, repairs are becoming frequent, or the refrigerant is being phased out. We compare the repair cost and expected remaining life against a replacement estimate.

Question 9

Do you service ductless mini-splits?

Accepted Answer

Yes. We install, repair, and maintain ductless mini-splits for homes, garages, additions, and rooms without ductwork.

Question 10

Can I install my own AC?

Accepted Answer

No. Air conditioning installation involves refrigerant handling, electrical work, and permitting. Federal law requires refrigerant handling by certified technicians, and most municipalities require permits and inspections for installation.
