Cold Supplies lists Miami-Dade, Broward and Palm Beach counties as its service area, including their incorporated cities and towns. Availability for a particular address, especially in an unincorporated area, should be confirmed when you call.

Cold Supplies lists its business hours as 24/7. That does not by itself guarantee an immediate technician visit or a specific response time. Call (954) 826-4957 to discuss your situation and confirm scheduling availability.

Call (954) 826-4957 and tell us your city or ZIP, when the system stopped cooling or heating, and what changed. We can discuss a date and time with a technician based on availability, then explain the diagnosis and practical options after the visit.

Share your location, thermostat setting, whether the indoor and outdoor units appear to run, and any ice, water, unusual noise, odor, or recent outage you noticed. If the equipment model is readily available, that can help; never open electrical or refrigerant compartments to find it.

The website describes AC repair, installation and replacement, preventive maintenance, indoor-air-quality concerns, and examples of ductwork and diagnostics in the work gallery. Call to confirm the scope and availability for your system and address.

A symptom can have several causes, so a reliable repair scope usually follows an equipment diagnosis. Ask what a visit includes, whether any fee applies, and what options will be explained before you authorize work. This site does not publish flat repair prices.

Confirm the thermostat is set to Cool and check the accessible filter and unobstructed registers. Note whether the indoor fan or outdoor unit runs. Do not open panels, handle wiring, or add refrigerant; have a technician diagnose persistent warm air.

A blocked condensate drain is one possible cause, but a pan, pump, frozen coil, or another issue can look similar. If water is pooling or approaching electrical equipment, stop cooling at the thermostat, avoid the wet area, and arrange qualified service.

Turn the thermostat cooling setting off and let the system thaw naturally. An accessible dirty filter or blocked register may be relevant, but airflow and refrigerant problems need qualified diagnosis. Do not chip ice, use heat, or open the equipment.

Stop using the system, do not repeatedly reset a breaker, and keep clear of damaged or wet electrical equipment. Contact a qualified HVAC or electrical professional; if there is smoke or an immediate fire danger, call emergency services.

A thermostat measures temperature, not the whole moisture load. Short cycles, system sizing, airflow, duct leakage, or a separate moisture source can be involved. A professional can evaluate cooling and humidity rather than guessing from one reading.

Sun exposure, airflow restrictions, duct leakage, room layout, or equipment operation can all affect room-to-room comfort. Compare the timing and affected rooms, check accessible registers without opening the unit, and ask for a whole-system assessment.

ENERGY STAR recommends checking central HVAC filters monthly and cleaning or changing them as appropriate. Follow the filter and equipment instructions; a very restrictive filter is not automatically a better choice for every system.

ENERGY STAR recommends a professional pre-season cooling check-up each year. Your equipment, heavy-use pattern and manufacturer instructions may call for a different maintenance conversation; ask what the visit actually includes.

Start with a diagnosis and a clear explanation of repair scope, equipment age and condition, comfort, and likely long-term costs. If replacement is proposed, ask how the new system will be sized for your home and South Florida humidity; do not choose by square footage alone.

Arrange routine service ahead of severe weather, keep outdoor equipment clear of ordinary debris without opening it, and plan for safe power-outage conditions. Never touch flood-damaged electrical equipment or operate a generator indoors; follow local emergency guidance.
