Apex Cool Air Conditioning HVAC FAQs

General HVAC Questions

How often should my HVAC system be serviced?

We recommend at least one professional maintenance visit per year. In Florida’s climate, most homeowners benefit from two — one in spring before cooling season and another in fall.

Most systems last between 10 and 15 years, depending on usage, maintenance, and build quality. Regular maintenance can extend that lifespan significantly.

If your system is over 10 years old, needs frequent repairs, or can’t maintain comfortable temperatures, it may be more cost-effective to replace it. Our technicians provide honest recommendations based on your system’s condition and efficiency.

Yes. Apex Cool Air Conditioning is fully licensed (License #CAC1816161) and insured for residential and commercial HVAC work.

Air Conditioning Repair FAQs

My air conditioner is blowing warm air — what should I do?

Check your thermostat settings and air filter first. If both are fine, the issue could be low refrigerant, a failed capacitor, or a dirty coil. Call for professional service before running the system further to prevent damage.

We offer same-day service whenever possible. Our technicians arrive with fully stocked vehicles to complete most repairs on the first visit.

No. Unusual sounds like grinding, squealing, or rattling often indicate mechanical or electrical problems. Running the system could cause further damage — shut it off and schedule a repair.

In many cases, yes. We can locate and repair leaks, then recharge your system to manufacturer specifications.

HVAC Installation and Replacement FAQs

What size HVAC system do I need for my home?

Proper system sizing depends on your home’s square footage, insulation, layout, and windows. We perform detailed load calculations to recommend the correct system size for maximum comfort and efficiency.

Most residential HVAC installations are completed within one day. Larger homes or complex duct replacements may take longer.

HVAC Maintenance FAQs

Our comprehensive tune-ups include coil cleaning, refrigerant level checks, thermostat calibration, drain line flushing, electrical inspection, and airflow verification.

Maintenance improves system efficiency, prevents costly breakdowns, and extends equipment life — saving you money over time.

Yes. Homeowners should check filters monthly and replace them every 1–3 months depending on usage and indoor air quality.

Ductwork and Air Quality FAQs

How do I know if my ducts are leaking?

Signs include uneven cooling, higher energy bills, or whistling sounds from vents. A professional inspection can confirm and repair leaks.

Yes. Over time, dust and debris can accumulate, affecting airflow and air quality. We recommend cleaning every 3–5 years or after major home renovations.

Troubleshooting FAQs

My AC won’t turn on — what should I check?

Ensure the thermostat is set correctly, the breaker is not tripped, and the air filter is clean. If everything looks fine and it still won’t start, call for service.

This can be caused by dirty coils, low refrigerant, duct leaks, or an undersized system. A professional inspection can identify the issue.

Restricted airflow or low refrigerant can cause coils to freeze. Turn off the system and call for service before damage occurs.

Your system may not be removing enough moisture due to dirty coils, airflow issues, or incorrect system sizing.
