Capacitors and contactors
The most common reason an outdoor unit hums but will not start. Usually a same-visit fix.
AC Repair · Open 24/7
Air conditioning repair for Miami homes and condos. We diagnose the real problem, tell you the price before we start, and get the cold air back.
In Miami the AC is not a comfort, it is the house. When it quits in August, the inside of a home can climb past 85 degrees in a few hours, and humidity starts working on drywall, cabinets and anything stored in closets. That is why we answer around the clock.
Every repair starts with a full diagnosis: refrigerant pressures, electrical parts, airflow, the drain line and the thermostat. Then we show you what failed, explain your options in plain language and give you the price before any work begins. No surprise add-ons when the job is done.
What we do
The most common reason an outdoor unit hums but will not start. Usually a same-visit fix.
We find the leak, repair it and recharge to the right pressure, instead of topping it off every summer.
Outdoor fan motors and indoor blower motors that stop, squeal or overheat.
Ice on the copper line or the indoor coil, traced back to airflow, refrigerant or a dirty coil.
Water in the pan, a tripped float switch or a leak from the ceiling, cleared and protected.
Blank screens, systems that will not respond and short cycling caused by bad controls.
Questions
The usual causes in Miami are a dirty air filter or coil, low refrigerant from a leak, a failed capacitor on the outdoor fan, or a frozen indoor coil. Turn the system off if you see ice on the copper line, and give us a call. Running it frozen can damage the compressor.
It depends on what failed. A capacitor and a refrigerant leak are very different jobs. We diagnose first and give you the exact price before we start, so you decide with the number in front of you.
Yes. We work on the central air conditioners, heat pumps, air handlers and ductless systems found in Miami homes and businesses, whatever the brand.
Sometimes. If the system is older and the repair is a major one, like a compressor, replacing it can cost less over the next few years. We give you both numbers and an honest recommendation, and the choice is yours.
We are open 24 hours, 7 days a week. Call or text and we will give you the soonest time we can be there.
