Thermostat wiring

The thermostat serves as the communication hub for the HVAC system, letting the unit know your temperature preferences. The thermostat wiring connects the device to the system, but these can become damaged, corroded, or loose.

When issues develop, the controls will be unresponsive, inaccurate temperature readings, or the equipment will unexpectedly cycle on/off. A quality and qualified heating and air conditioning professional will inspect the device for loose connections or frayed wires.

Capacitors and contactors

Electrical energy is stored and supplied by capacitors to start and run the AC motors. These can fail for a few reasons, whether an electrical surge, age, or excessive heat exposure. Signs of a failure:

• The system struggles to start or shuts off unexpectedly
• The system develops a humming noise

Contactors control the electricity flow to various system components, including the condenser fan and compressor. These switches wear over time from heavy use or can become damaged from electrical arcing. When the contactor is faulty, it impacts the system’s overall performance, often leading to difficulty turning it on/off.

Circuit breaker issues

Circuit breakers and fuses are designed to protect the heating and cooling equipment from electrical overloads and short circuits. When the circuits trip or the fuses blow, either the wiring is faulty, or the system is drawing too much current.

You want to reset the tripped breaker; however, repeatedly doing so without fixing the root of the problem can be hazardous. When the circuit continues to trip, it’s a sign to reach out for immediate professional attention.

Ignoring these red flags could lead to serious electrical hazards, including the potential for a fire. A specialist will diagnose and fix the underlying issue instead of addressing only the symptoms.

When you become familiar with the key components, you’ll be better prepared to troubleshoot potential problems like the following.

Short circuits/electrical fires

Short circuits happen when electrical current go off their intended path, leading to sparks and possibly a fire. Warning signs to pay attention for include scorch marks on the HVAC unit, burning smells, visible sparks.

If you notice any signs, the system should be shut off immediately before contacting an HVAC repair specialist.

Voltage irregularities

Voltage irregularities can harm the heating and cooling components, causing damage or inefficient operation. Symptoms to pay attention to are fluctuations in operation and dimmed lights when starting. An electrician is typically needed to solve the underlying electrical supply issues.

HVAC Electrical Troubleshooting

Safety should be a focus before attempting to troubleshoot HVAC electrical issues in your Ozark household. The power should be shut off at the breaker box for the HVAC system to prevent electric shock. Personal protective equipment should be worn such as safety glasses and Insulated gloves.

No components or exposed wires should be touched without understanding their purpose.

Basic troubleshooting

With simple troubleshooting, you want to start with the thermostat to ensure the temperature and mode are set correctly and change out the batteries if needed.  Inspect the electric panel to ensure the breakers and fuses are intact. These should be reset or replaced if needed.

Air filters and vents should be clean and unobstructed to prevent stress and strain on the system.

When basic troubleshooting is ineffective or problems persist, such as burning smells, odd noises or frequent breakdowns, a specialist will need to inspect the equipment.  

An average homeowner lacking proper training in complex repairs faces potential harm or can create more damage to the system when trying to handle these on their own. Read here for expert tips for bringing your home to a desired temperature.

Upgrades should comply with current codes and be installed by a licensed professional.
