Services Offered by Furnace Repair Companies

Your local furnace repair company provides various services to keep your system working effectively. We go over some common services below.

Repair and Maintenance

Timely repairs help extend your furnace's life span and optimize its energy efficiency, on top of restoring furnace function. Furnace repair companies can diagnose and fix most common furnace issues. These include malfunctioning thermostats, clogged air filters, or broken blower motors. Qualified HVAC technicians can also handle problems such as faulty ignitions, damaged heat exchangers, possible gas leaks, and malfunctioning thermostats. Your furnace repair company can also perform routine HVAC maintenance to help avoid unnecessary breakdowns. Your technician will make sure all components function properly by inspecting your furnace, cleaning it, replacing air filters, and lubricating moving parts.

Installation

Your HVAC provider can help upgrade your furnace to a more energy-efficient model, like a heat pump. If your system is beyond repair, they can also help install an entire new furnace. Your technician will start by assessing your home's layout and heating needs. Then, the tech will recommend the right furnace model for your requirements and budget. Your HVAC professional can integrate a new system with existing thermostats and air ducts. They're trained to follow industry safety protocols and standards to ensure proper furnace replacement and connection. To be sure everything runs optimally, your technician will complete a final inspection following installation.

Inspection

If you find that your furnace isn’t turning on, your furnace repair company will probably recommend a thorough inspection to identify potential causes. This process involves a technician examining each component of your furnace. The inspection usually includes checking for any gas or fuel leaks, testing the thermostat's accuracy, cleaning and replacing air filters, inspecting the burner and ignition system, and examining the heat exchanger for cracks or damage. We recommend an annual inspection, during which a technician will check your heating system's efficiency and safety and make any necessary adjustments or repairs. Regular inspections and tune-ups help prevent potential breakdowns, ensure optimal heating performance, and promote safe living during colder months.

Emergency Services

Emergency furnace repair services will restore heat to your home if your furnace breaks down on a cold night. Many companies offer 24/7 services to help get your furnace up and running as soon as possible. These services help with unexpected breakdowns, malfunctions, and other safety concerns. Emergency services are more expensive than a scheduled service, but protecting your health is worth it. Furnace failure can cause serious discomfort and health risks from decreased indoor air quality, especially if it breaks down during extreme weather conditions when it's not possible to open windows for fresh air.

Factors To Consider When Choosing a Local Charleston Furnace Repair Service

There are several important considerations for choosing a local Charleston furnace repair company. We go over some important factors below.

  • Cost: Look for a company that provides all the services you need, and that offers transparent and competitive pricing. Compare multiple Charleston furnace repair companies. Beware of ones that offer extremely low rates, as they may employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Check for guarantees or warranties offered by the furnace repair service. A trustworthy company should back its work with guarantees on parts and repair work. This assurance gives you peace of mind knowing you can rely on your service provider if any problems arise after repairs.
  • Licensing: Make sure that your furnace repair provider has all required licenses and certifications. This ensures that its technicians are qualified and trained to safely handle furnace repairs. HVAC contractors in South Carolina must obtain a contractor's license from the South Carolina Residential Builders Commission.
  • Qualifications: Inquire about a company's training policies and the experience of its technicians. Companies that provide ongoing training are more likely to have technicians that use the latest repair techniques. You want a company that employs well-trained technicians with experience working with various furnace makes and models.
  • Reputation and reviews: Check online reviews and customer testimonials to get a feel for a provider's reputation. Generally positive feedback is indicative of quality services. You can also verify a company's commitment to customer satisfaction by looking at how it addresses negative feedback or complaints.

How Much Does a Furnace Repair Cost?

Certain factors affect the cost of repairing your furnace. These include the type of HVAC unit, extent of the damage, and price of replacement parts. On average, furnace repair costs $440, though this varies depending on the details. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $81–$404
  • Cleaning: $48–$65
  • Cracked heat exchanger: $1,617–$2,829
  • Damaged blower bearings: $24–$121
