Preferred Home Services installs, replaces, repairs, and maintains Generac home standby generators throughout the Charleston and Greenville areas. Our electricians work with the generator, automatic transfer switch, electrical connections, controls, and other components that allow Generac equipment to provide dependable backup power.

Our generator services include support for homeowners with existing Generac units or are considering Generac equipment for their homes.

Our Generac Generator Services

Generac systems require service that accounts for the installed model, controller, transfer equipment, fuel configuration, operating history, and manufacturer requirements. We provide support throughout the life of the equipment.

Generac Generator Installation

We install Generac home standby generators based on the property’s backup-power requirements and existing infrastructure. Installation may include positioning the equipment, installing a compatible automatic transfer switch, completing electrical connections, coordinating the fuel supply, configuring applicable controls, and testing the system.

If the existing electrical service cannot support the proposed installation, we can explain whether an electrical panel upgrade is needed. Any required preparation is identified before installation begins.

Generac Generator Replacement

A Generac generator may need replacement when it becomes unreliable, requires repeated repairs, lacks sufficient capacity, or can no longer be supported with practical repairs. We evaluate the existing unit and connected equipment before recommending replacement.

The transfer switch and other components are also checked for compatibility with the proposed generator. Existing equipment is reused only when it can operate safely and correctly with the replacement system.

Generac Generator Repair

Controller alerts, failed exercise cycles, battery problems, transfer failures, and unexpected shutdowns can prevent a Generac generator from operating when utility power is lost. Our electricians diagnose the condition before recommending a repair.

Generac repair may involve the generator, starting system, controls, accessible fuel components, electrical connections, or transfer equipment. Broader household problems outside the generator system can be addressed through our electrical repair services.

Generac Generator Maintenance

Generac maintenance requirements depend on the model, operating hours, fuel type, age, and service history. We follow the needs of the installed equipment rather than treating every generator the same.

Maintenance may include checking applicable fluids and filters, inspecting the battery and charging system, reviewing controller alerts, examining accessible connections, testing the exercise cycle, and confirming transfer operation. We document concerns and explain when a separate repair is recommended.

Signs Your Generac Generator Needs Service

A Generac generator may communicate problems through its controller, indicator lights, exercise behavior, or Mobile Link notifications when that feature is available. Homeowners should schedule service when the equipment shows a warning or stops behaving as expected.

Common reasons to request Generac service include:

  • A red or yellow status indicator

  • A controller fault or maintenance message

  • Failure to complete a scheduled exercise cycle

  • Failure to start during an outage

  • Generator operation without power transferring to the home

  • Repeated battery or charging problems

  • Unexpected shutdowns

  • Oil, coolant, or fuel leaks

  • Unusual noises or vibration

  • Mobile Link alerts indicating that attention is needed

The displayed code or alert provides useful diagnostic information but does not always identify the underlying cause by itself. We evaluate the complete Generac system before recommending corrective work.

Generac Automatic Transfer Switch Service

The automatic transfer switch detects a loss of utility power and controls the transition between utility and generator electricity. A generator may start correctly but still fail to power the home when the transfer equipment or its connections are not operating properly.

We inspect and test compatible Generac transfer equipment as part of applicable installation, repair, and maintenance work. This helps determine whether a problem originates in the generator, transfer switch, electrical connections, or another part of the backup-power system.

Kevin replaced a two bulb flood light and repaired a second light that had the internal bulb holder loose inside the globe. He made it look easy and was a pleasure to watch, a true professional and the best I have seen. He even parked his vehicle on the road rather than risk blocking me out of my driveway.

Technician came out and assessed the problems with our plumbing pipes under in the bathrooms and under the house. They were wonderful in assisting my husband and I with getting a Loan company to cover the plumbing job.

I recently decided to installl a new HVAC system and meet with Logan to get an estimate on the cost.
He was right on time with a big smile and warm handshake.
We sat down and discussed what my needs were and how he could make things work for ME! He did a thorough walk through, explained his findings and was very patient answering my questions.
He then discussed with me his recomendations which would fit my needs.I never felt I was being pressured or rushed to make my decision.
I am happy to have found this company and a dedicated employee like Logan to help me get my new HVAC!

Follow up :
Had my new HVAC installed last week and Vince and Alex did a great job! They had some tight spots to work installing but they knew what they were doing and got everything done in one day.
They answered questions and educated me on how the system worked. They registered my system with the manufacturer for me which was so helpful.
Few days later I had a few questions on the outside unit. They came back a few hours later and made sure all was running properly.
Great company with excellent teamwork.
Will use again!

Had maintenance of my HVAC today performed by Ben. He greeted me with a smile and was on time and courteous.
He sat down with me explaining what he would be doing on the units and mindful of my questions. He showed me areas of concern and offered options on how they could be repaired or replaced.He gave me time to discuss the choices and I never felt rushed or pressured on my decision making.
Preferred is lucky to have Ben as an employee !
Thanks Ben!
