Air Conditioning FAQ for Port St. Lucie Homeowners

Common questions

How do homeowners decide whether to repair or replace an air conditioner?

Two factors generally matter most: system age and repair cost relative to replacement. Systems under about 10 years old with a single failed component are usually worth repairing. Systems past 12 to 15 years facing a compressor, coil, or major refrigerant repair are usually worth comparing against replacement, since a second major failure can be likely within a few seasons.

Why does an AC run constantly without cooling the house?

Continuous runtime with poor cooling generally means the system is producing less capacity than the house is losing. Low refrigerant charge, a dirty condenser coil, a restricted evaporator coil, and duct leakage in a hot attic are among the common causes. A measured temperature split across the coil helps separate a refrigerant problem from an airflow problem.

What temperature split should a system produce?

Most residential systems produce roughly a 16 to 22 degree difference between return air and supply air under normal conditions. A split well below that range can point to a refrigerant or compressor issue, while a split well above it often indicates restricted airflow.

Should a homeowner replace the air filter themselves?

Yes, this is a routine homeowner task. Standard one-inch filters in Port St. Lucie homes generally need changing every 30 to 60 days during cooling season, and more often with pets. A loaded filter reduces airflow, lowers capacity, and can freeze the evaporator coil.

How often does a system need professional maintenance?

Once a year is a common minimum for this climate, and twice a year is common for systems near the coast or running heavy loads. A maintenance visit typically covers coil cleaning, condensate drain clearing and treatment, electrical inspection, refrigerant verification, and airflow measurement.

Why does water drip from an indoor unit?

The evaporator coil removes a significant amount of moisture from the air each day in Florida, and that water leaves through a condensate drain. When algae or debris blocks the drain, the pan can overflow. Clearing and treating the line is the standard correction, and a working float switch helps prevent overflow damage.

Is refrigerant supposed to be topped off periodically?

No. A sealed refrigerant circuit does not consume refrigerant under normal operation. If the charge is low, there is typically a leak. Adding refrigerant without locating and repairing the leak generally means the same issue returns, often within a season.

How long does a diagnostic visit usually take?

A diagnostic visit generally takes 45 to 90 minutes depending on the fault. Straightforward repairs such as a capacitor, contactor, drain clearing, or coil cleaning are often completed the same visit, while refrigerant leak repairs and component replacements may require a return visit if parts are not on hand.

Is service available outside standard hours?

This varies by provider. A service request submitted through the contact form is reviewed and a provider will follow up regarding availability; no specific response time or hours can be guaranteed on this page.

What can be checked before requesting service?

Confirm the thermostat is set to cool with a setpoint below room temperature, check that both the air handler and condenser breakers are on, look at the air filter, and check whether the condensate drain float switch has tripped. These checks resolve a meaningful share of no-cooling situations without further work.

Does salt air affect equipment near the water?

Outdoor equipment closer to waterways and coastal air can experience additional corrosion on condenser coils, fan hardware, and electrical connections compared with equipment further inland. Keeping the exterior of the unit clear of debris and lightly rinsed can help slow that process, though internal cleaning should be left to qualified service personnel.

Are written estimates provided before work begins?

Reputable providers typically present measured findings and the cost of each option in writing before starting repair work, and proceed only once the homeowner authorizes it. Specific practices vary by provider.
