The service
What ac repair is, what a visit covers and where the line is.
The short answer
AC repair looks into why a central air conditioner or heat pump in cooling mode does not cool, freezes up, leaks water, runs short cycles or trips a breaker. AC Repair in South Pasadena is booked through pros who cover its 2 ZIP codes. In South Pasadena, the dry months are the easiest time for outside work, and early fall is a good time to prepare before the winter rains. NorTech lists independent pros who set their own price and warranty, and the booking goes to the one you choose.
If ac repair is an emergency
A failed AC in extreme heat is a health risk, especially for infants, older adults and anyone with a medical condition. Water leaking from the unit can also damage ceilings and floors.
Treat it as urgent if
- Someone in the home is showing signs of heat illness such as confusion, vomiting or very hot dry skin
- The breaker trips repeatedly, or you smell burning near the unit
- Water is dripping through a ceiling or onto electrical equipment
- Indoor temperature is dangerously high and a baby, older adult or ill person is at home
What a ac repair visit includes
What is included depends on the jobs you pick and on how each pro sets up their visit and timing. You see the exact scope with each pro's price before you book.
- Diagnostic
- Part repair/replacement
- Refrigerant/airflow check
- Your pro’s own workmanship warranty

What shapes a ac repair job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
What is not part of ac repair
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials together reach $1,000 or more is done by a licensed contractor, and NorTech flags it before you book.
- Replacing the compressor, the evaporator coil or the whole air conditioner. A large repair or replacement is licensed-trade work and often reaches that limit.
- Refrigerant handling, leak repair and charging requires a license and the federal refrigerant certification, held by the pros who do it.
- New circuits, panel work and rewiring beyond the unit disconnect: that is a licensed electrician.
- Ductwork repair and duct cleaning, which have their own services on NorTech.
- Replacing a gas furnace or heat source. That is a separate HVAC service.
License and permits for ac repair
The sealed refrigerant circuit, including leak repair, evacuation and charging, is licensed-trade work and needs a federal refrigerant certification. Pros who do this work hold both, and simple repairs such as a drain line or a capacitor are routine.
Part replacement and refrigerant repair on an existing system generally do not need a permit. Replacing the condenser, the coil or the whole system commonly does. Your pro tells you when a permit applies.
Check the pro profile for their license, refrigerant certification and insurance. Ask for the readings recorded at the end of the visit, such as temperature split and pressures, and keep the invoice.

Before you book ac repair
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Check the thermostat and breaker
Make sure the thermostat is set to cool with a temperature below the room reading, and that the breaker and the outdoor disconnect are on. Reset a tripped breaker once only.
Look at the filter and the vents
A dirty filter and closed or blocked vents are common causes of weak cooling and frozen coils. Replace the filter and open registers before the visit.
Turn it off if you see ice
Ice on the indoor coil or the copper line means the system should stay off until it thaws. Running it frozen can damage the compressor and flood the drain pan.
Clear space around the outdoor unit
Remove leaves, cottonwood and clutter and keep plants a couple of feet away. Do not spray into the unit with a pressure washer.
Describe sounds and smells
Hissing, buzzing, clicking, burning smells and a hot or cold air pattern all help the pro narrow down the part. Note when it happens and how long it lasts.
Find the model and age
Photograph the data labels on the outdoor unit and the indoor coil or air handler. The age and refrigerant type help decide whether a repair is worth doing.

Best time to book ac repair
An air conditioner sits idle through winter, so repairs are easiest before the first hot days. Pros are far busier during a summer heat wave, so an off-season check gives you more room to schedule and a chance to catch a problem before the hottest day. In South Pasadena, the dry months are the easiest time for outside work, and early fall is a good time to prepare before the winter rains.
Often booked together with ac repair
Book several services with one pro. Pros set their own bundle discounts.
A yearly tune-up cleans coils and checks the parts that most often fail in summer.
A thermostat that does not call for cooling can look like a dead AC and is checked in the same visit.
Leaking or crushed ducts waste cooling and are often found while diagnosing a weak system.
When the compressor or coil fails on an old system, replacing the whole system can be the better choice.
