Yes. The technician explains what’s wrong and gives you a clear price before any repair work starts, so there are no surprises.

The most common causes are a dirty air filter, a frozen evaporator coil, a failed capacitor or fan motor, a compressor problem, or low refrigerant from a leak. Check that the thermostat is set to cool and replace a dirty filter. If you see ice on the unit, turn the system off and call for service so the coil can thaw and the cause can be found.

It depends on the age of the system, the cost of the repair and how often it has broken down. Systems that are past 10 to 15 years old, or that need repeated expensive repairs, are often better replaced. We’ll give you an honest recommendation, and we’ll tell you when a repair is the smarter choice.

Same-day service is available in many cases. Call (954) 629-9825 and the team will tell you the soonest window. The phone line is open 24 hours.

A straightforward replacement is often completed in a single day. Jobs that involve ductwork changes, new electrical work or a hard-to-reach air handler can take longer. You’ll get a clear timeline before work begins.

Yes. Replacing an AC system in Florida requires a mechanical permit and an inspection. A proper installation includes both, so ask about it with any contractor you’re comparing.

Federal rules set minimum efficiency by region, and Florida is in the Southeast zone. Higher-efficiency systems cost more up front but can lower monthly bills, especially in a climate where the AC runs most of the year. We’ll help you compare options based on how long you plan to stay in the home.

Yes. Master Tech Air offers the FPL rebate on qualifying new systems. Rebates are for FPL customers, and the rules and amounts are set by FPL, so ask the team whether the system you are considering qualifies.

Military, police and customers 55 and older get 10% off. Mention it when you book your estimate and the team will confirm how it applies to your job.

Yes, when it’s sized correctly. Garages are tough because of heat coming through the roof, walls and garage door, so proper sizing and good insulation matter. A correctly sized ductless system is one of the most common ways to make a garage usable year-round.

Multi-zone systems connect several indoor units to a single outdoor unit, so you can cool multiple rooms with separate temperature control for each. We’ll tell you whether single-zone or multi-zone fits your layout.

Most mini splits are heat pumps, so they can heat as well as cool. In South Florida that’s handy for the few cool mornings each year.

At least once a year is the common minimum, and many homeowners schedule twice a year, once before the long cooling season and once mid-season, because the system runs so much. Coastal homes and older systems benefit most from the extra visit.

A system with clean coils, proper airflow and correct refrigerant levels doesn’t have to work as hard to cool your home, which generally means lower energy use. Maintenance also catches small problems before they turn into expensive failures.

Coil cleaning, a condensate drain flush, electrical and component testing, refrigerant and pressure checks, and a filter and thermostat check, followed by a clear report of what the technician found.

UV-C lights installed at the evaporator coil are designed to limit the growth of mold and bacteria on the coil and drain pan surfaces they shine on. Results vary by home, and a UV light works best alongside good filtration, a clean system and proper humidity control, not as a replacement for them.

It can help reduce some indoor triggers like dust, pollen and mold, but it isn’t a medical treatment. If you have serious allergies or asthma, talk with your doctor as well as your AC contractor.

In most cases, yes. UV lights, filters and humidity control can usually be added to an existing system without replacing it. A technician can confirm what fits yours.

Uneven temperatures, high bills, excess dust and rooms that never get cool are common signs. A technician can confirm by inspecting the ducts and measuring airflow. In many homes the leaks are in the attic where they can’t be seen from inside.

It can be, especially after construction, a mold or pest issue, or if the ducts are visibly dusty. We’ll tell you honestly whether cleaning will help in your home or whether sealing and repair matter more.

Yes. Leaks and restrictions force the system to run longer to cool the same space, which wears it out sooner and raises your bill. Fixing the ducts can improve comfort without touching the AC itself.

If you smell burning or see smoke, turn the system off at the thermostat and the breaker and call right away. If you see ice on the unit or water leaking, turn the system off to prevent more damage. Keep blinds closed, run fans and stay hydrated while you wait.

Master Tech Air lists its hours as open 24 hours. Call (954) 629-9825 any time to reach the team.

Arrival time depends on where technicians are when you call and how urgent your situation is. The person you speak with will give you an honest window instead of an overpromise.

Most homes are only cold a handful of days each year, but those days can be uncomfortable. Because most Florida systems heat with the same equipment that cools, having it working costs nothing extra to maintain during a regular tune-up.

A heat pump is an air conditioner that can also run in reverse to heat your home by moving warmth indoors. It’s the most common way to heat a Florida home.

Yes. Running the heat for a few minutes on a mild day tells you whether it works. It’s better to find a problem now than on the coldest morning of the year.
