AC Repair
When a central air system stops keeping up with the heat, most homeowners don't have time to diagnose the problem themselves. HVAC Service Line helps you get in touch with an independent HVAC company in your area that takes AC repair calls, so you can describe what's happening and get a technician's read on it.
Signs it's time to reach out
- Warm air coming from the vents even though the thermostat is set to cool
- The outdoor condenser unit is running constantly, or won't kick on at all
- Ice forming on the refrigerant lines or the indoor coil
- Water pooling near the indoor air handler or dripping from the ceiling
- A sharp rise in cooling costs with no change in how the system is used
- Grinding, clicking, or squealing sounds from the outdoor unit
- Musty or burning odors when the system runs
When homeowners typically call
- The system is running but the house isn't cooling down
- Airflow from the vents feels weak across the whole house
- The system short-cycles — turning on and off in quick bursts
- There's a burning smell or an audible electrical hum from the unit
- The thermostat display is blank or unresponsive
What a company may inspect
This varies by company, but a visit for ac repair often includes a look at:
Refrigerant charge and pressure at the service ports
Condition of the condenser coil, evaporator coil, and air filter
Electrical connections, capacitors, and the contactor
Condensate drain line for clogs or backups
Thermostat wiring and calibration
Blower motor operation and airflow across the coil
Questions worth asking
- What's the likely cause based on what I'm describing, and could it be more than one issue?
- Is this a repair worth making given the age and condition of the system?
- What would confirming the diagnosis on-site typically involve?
- Are parts for this system's make and model readily available?
- What would keep this problem from recurring?
AC Repair FAQ
Why is my AC running but not cooling the house? +
This usually points to one of a few things: low refrigerant from a leak, a dirty coil or filter restricting airflow, a failing compressor, or a duct problem losing cooled air before it reaches the rooms. A technician can narrow it down with pressure readings and a visual inspection of the coils and airflow path.
Is it normal for ice to form on my air conditioner? +
No — ice on the refrigerant lines or coil is a sign something is wrong, most often restricted airflow (a dirty filter or blocked vents) or low refrigerant. Running the system with ice on it can strain the compressor, so it's worth having someone look at it before continuing to run the AC on cooling mode.
How fast can someone come look at my AC? +
Availability depends on the company and your location. Submit a request or call, and we'll connect you with a company in the network that can speak to their current scheduling, including same-day or emergency options where available.
