Plano AC Electrical Troubleshooting & Repair | 24/7 NATE-Certified

How We Diagnose Electrical Issues (NEC-Compliant, TDLR-Licensed)

Advanced Tools: Multimeters, Clamp Meters, Megger, Amp Draw

We arrive with professional-grade equipment including multimeters, clamp meters, and megohmmeter (megger) devices for insulation testing. Our techs measure amperage (amp draw), follow manufacturer wiring diagrams, and read error codes/lockout codes to diagnose problems accurately the first time. We service all major brands (Carrier, Trane, Lennox, Goodman, Rheem, Daikin, Amana).

We Fix Shorts, Open Circuits, Wiring Faults, and Voltage Drop

Most AC electrical problems involve capacitors, contactors, or relays. We also fix wiring faults, open circuits, replace bad fuses, and repair ground fault (short-to-ground) issues. Our trucks carry common parts for faster repairs—8 out of 10 electrical repairs are completed on the first visit thanks to our stocked trucks.

Full-System Electrical Health Check (Indoor Air Handler & Outdoor Condenser)

We inspect both indoor air handler and outdoor condenser components, checking line voltage (high voltage) connections and testing for voltage drop issues. This complete approach catches problems before they cause system downtime during peak summer heat. All our work meets National Electrical Code (NEC) standards and Texas regulations through our TDLR license, ensuring safe, legal repairs that protect your home and warranty. We use OEM-grade parts and provide documentation to maintain manufacturer warranty eligibility.

Components We Repair or Replace

Capacitors (Run/Start), Contactors, Relays

Failed capacitors cause most AC electrical problems. We test and replace both run capacitors and start capacitors, plus worn contactors and relays that control power to your compressor.

Control Boards, Transformers, 24V Low-Voltage Wiring

Bad control boards get replaced with exact matches to restore proper operation. The transformer steps down voltage for your control circuit. We trace problems in the 24V low-voltage wiring system that controls your AC.

Blower Motors, Condenser Fan Motors, Hard-Start Kits

When your blower motor or condenser fan motor fails, we test windings and bearings. We also install hard-start kits to help aging compressors start more easily and reduce strain on electrical components.

Fuses, Disconnect Switches, GFCI/AFCI, Circuit Breakers

We replace blown fuses, repair disconnect switches, and ensure proper GFCI/AFCI protection for safety. Faulty circuit breakers get replaced to prevent future trips and protect your system.

Compressor Electrical: Windings, Short-to-Ground, Compressor Relay

Compressor problems require careful testing of compressor windings and checking for short-to-ground issues. We measure amp draw to determine if your compressor relay needs replacement.

Surge Protection Installation & Voltage Drop Corrections

We install surge protection to guard against lightning and power surges. Voltage drop issues get corrected to improve energy efficiency and extend equipment life. Properly corrected voltage and balanced amp draw lead to lower utility bills and longer motor/compressor life, saving you money long-term.

Why Hire a Pro vs. DIY

Safety Risks, Code, and Manufacturer Warranty Protection

AC electrical work involves dangerous voltages up to 240 volts. One mistake can cause electrocution, fire, or destroy expensive components. DIY repairs also void your manufacturer warranty and may violate insurance policies. Our certified technicians hold current licensing (Texas HVAC/Electrical regulations) and stay updated on code changes. This expertise ensures repairs last and keep your family safe while preserving your warranty coverage.

HVAC Tech vs. Licensed Electrician: When You Need Each

HVAC techs handle most AC electrical issues, but some problems require a licensed electrician. We'll tell you upfront if you need additional help for panel or service upgrades. We coordinate scheduling and share diagnostic reports directly with partner electricians when needed, ensuring seamless service and keeping your diagnostic fee credited toward the total repair.

Pricing, Warranties, and Financing

What Affects Cost (Parts, Labor, Emergency, Accessibility)

Repair costs depend on several factors:

• Part type (capacitor vs. motor/control board)

• Labor time and complexity

• After-hours/emergency service rates

• Accessibility issues/attic work

• Need for electrician/panel work

Parts & Labor Warranties + Diagnostic Fee Credited

We stand behind our work with solid warranties on parts and labor. Most repairs include at least a one-year guarantee for your peace of mind. When you approve repairs, we credit the diagnostic fee toward your total bill, making fixing problems more affordable.

Payment Options & Financing

We accept all major credit cards, checks, and offer financing for larger repairs with 0% promotional options on approved credit and low monthly payments. Don't let cost prevent you from staying cool—ask about our flexible payment plans.
