AC Repair in Orlando, FL

Every AC repair starts with an accurate diagnosis. Our technicians use professional-grade diagnostic tools to identify the root cause of cooling failures, unusual noises, short cycling, and airflow problems. We check electrical connections, refrigerant levels, coil condition, and system pressure before recommending any repair.

This approach prevents unnecessary part replacements and keeps costs transparent. You'll know exactly what's wrong and what it takes to fix it before any work begins.

Orlando summers regularly push into the mid-90s, and indoor temperatures can climb fast when your AC goes down. R.J. Kielty offers 24-hour emergency AC repair Monday through Friday to handle urgent breakdowns when you need help most.

Our emergency response covers everything from total system failures to tripped breakers, frozen evaporator coils, and capacitor blowouts. We stock commonly needed parts on our service vehicles, which means many emergency repairs can be completed the same day.

Central air systems are the most common cooling setup in Orlando homes and commercial buildings. We repair all major brands and models, including Carrier, Trane, Lennox, Rheem, Goodman, and York. Common central AC repairs include blower motor replacement, ductwork leak sealing, drain line clearing, and control board repair.

If your system is blowing warm air, cycling on and off frequently, or producing weak airflow, these are signs your central AC needs professional attention.

Low refrigerant is one of the most common reasons an AC system stops cooling properly. A slow refrigerant leak can reduce cooling efficiency by 20% or more, according to the U.S. Department of Energy. Our technicians locate leaks using electronic leak detectors and nitrogen pressure testing, then repair the source before recharging the system to manufacturer specifications.

Simply adding refrigerant without fixing the leak is a temporary patch that wastes money. We fix the problem at its source.

A malfunctioning thermostat can cause uneven temperatures, constant running, or a system that won't turn on at all. We troubleshoot and repair both traditional and smart thermostats. If your thermostat is outdated or incompatible with your current system, we can install a programmable or Wi-Fi-enabled replacement that gives you better control over comfort and energy usage.

The compressor and condenser are the most critical, and most expensive, components of your AC system. Compressor failure can result from electrical issues, refrigerant problems, or simple age. Condenser coils can become clogged with dirt and debris, especially during Orlando's pollen-heavy spring months.

We repair and replace compressors, condenser fan motors, contactors, and coils. If your outdoor unit is making grinding or buzzing sounds, or if it's running but not producing cold air, the compressor or condenser is likely involved.
