Office Phone Systems Repair Cost

Office phone systems require repair work from time to time. The issues that arise with business phones are often more complex than those with home phone systems. This difference is reflected in the average repair cost for each.

Average Repair Cost





Who's responsible for the repairs depends on the issue and the service provider. Typically, if the cause of the issue is due to a malfunction outside of the business or home, then the service provider is responsible for the costs. If the cause is due to an issue inside the building, such as installing a phone jack or installing a new electrical switch, the business or homeowner is responsible.

VoIP phone systems are the least expensive to repair overall. These systems rely on the Internet for service instead of traditional landlines. They're common in homes and businesses. Thus, it's important to install a computer network prior to setting up a VoIP system. The drawback is that, if the network goes down, the phone system goes down, too.

Private branch exchange (PBX) systems are like VoIP, except that the system is hosted on-site. Additionally, the organization owns all the equipment rather than leasing from the service provider. These systems are ideal for mid- or large-size businesses.

Key system units (KSU) have central control units that connect the extensions on the system. With this system, you can make internal calls easily and see which lines are in use by glancing at the light panel. These systems are ideal for smaller companies.

Home Or Office Phone Repair Cost Factors

Parts and labor are the two factors that dictate how much home or office phone repairs cost. Parts are typically inexpensive unless they're for outdated systems or require a special order. Additionally, upgrading an electrical panel or other wiring to accommodate phone systems can raise the cost considerably. Labor makes up a bulk of the cost of phone system repairs. A handyman or electrician is qualified to make the repairs and costs an average of $65 to $85 per hour, though this figure can change based on location. In addition to the time needed to make the repair, the handyman or electrician will charge for the time it takes to diagnose the issue.

Common Office Phone Systems Repairs

Dropped calls, poor connections or lack of dial tone are all common problems in office phone systems. Fortunately, the repairs are also common. Typical office phone system repairs include:

  • Faulty Wiring: Faulty phone or electrical wiring can lead to several issues, including static interference or choppy calls, inability to dial in or out and constant busy signals. The average cost of electrical work to repair office phone system wiring is $100 per line.
  • Malfunctioning Power Supply: Phone systems require electricity to function properly. If the phone has a poor connection, lacks a dial tone or drops calls, then the likely culprit is a malfunctioning power supply. Replacing the power supply costs $20 on average. If the power supply is working properly, consider replacing the electrical outlet.
  • Broken Splitter: For some phone systems, a splitter is necessary to connect other extensions to the main line. If the splitter is faulty, it can affect all phones on the system. Fortunately, the fix is simple and costs about $10 to replace a splitter on average.
  • Replacing Router or Phone System: Sometimes the cause of the issues with the phone system is that the entire phone system itself or the router is defective. If this is the case, the only remedy is replacement. Depending on the type of phone system, the cost for replacement is between $250 and $500.

DIY Or Hire An Electrician?

A skilled DIYer can often repair a phone system. However, if you’ve never worked electricity, then it's best to hire an electrician. Electricians can diagnose the problem quickly and make the necessary repairs, which is important if you need the phone for business use. Additionally, hiring an electrician reduces the risk of damaging parts or equipment or injuring yourself.
