Services Offered by Furnace Repair Companies

Furnace repair companies provide various to keep your furnace working at maximum efficiency. We outline some common offerings below.

Repair and Maintenance

Professional and timely repairs can restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair professionals can diagnose and repair any issues with your furnace, including a malfunctioning thermostat, clogged air filter, or broken blower motor. Qualified HVAC technicians examine and fix individual problems such as faulty ignitions, malfunctioning thermostats, possible gas leaks, or damaged heat exchangers. Your furnace repair company can also complete routine HVAC system upkeep to help avoid unnecessary breakdowns. Your technician will ensure that all components function properly by inspecting your furnace, cleaning it, lubricating moving parts, and replacing air filters.

Installation

HVAC companies can also install a new furnace if your furnace is beyond repair, or if you're planning on upgrading to a more energy-efficient model, like a heat pump. First, skilled technicians assess your home's layout and heating needs. Then, they recommend the most suitable furnace model based on your budget and home requirements. HVAC technicians follow safety protocols and standards set by the industry to ensure safe furnace replacement and connection. They also integrate a new system with existing thermostats and air ducts. Following installation, the company does one last inspection to ensure the furnace runs optimally.

Inspection

If your furnace isn’t turning on, schedule a thorough inspection through a furnace repair provider. A technician will examine each of the furnace's components to look for possible issues. Inspections usually include cleaning and replacing air filters, checking for any gas or fuel leaks, examining the heat exchanger for cracks or damage, testing the thermostat's accuracy, and inspecting the burner and ignition system. A technician will check the heating system's efficiency and safety and make any necessary adjustments or repairs. Annual furnace tune-ups help ensure optimal performance and help avoid breakdowns, which promotes a safe living environment during colder months.

Emergency Services

If your furnace breaks down in winter, some furnace repair companies offer emergency repair services to get your heat back up and running quickly. These services are available around the clock for unexpected malfunctions, breakdowns, and other safety concerns. When a furnace fails during extreme weather, and it's not possible to open windows for fresh air, it can pose serious discomfort and health risks from poor indoor air quality. Emergency services cost more than scheduled services, but it’s worth it to protect your health.

Factors To Consider When Choosing a Local Knoxville Furnace Repair Service

There are multiple factors to consider when hiring a local Knoxville furnace repair company. We’ve detailed them below.

  • Cost: Look for a company that provides all the services you need, and that offers transparent and competitive pricing. Compare multiple Knoxville furnace repair companies. Beware of ones with extremely low rates, as many use subpar replacement parts and low-quality workmanship.
  • Guarantees: Look into the guarantees or warranties provided by the furnace repair service. A reputable company should stand behind its work and offer a reasonable guarantee on parts and repair work. This provides peace of mind knowing you can depend on the service provider if issues arise after repairs.
  • Licensing: Make sure that your furnace repair provider has all necessary licenses and certifications. This ensures that its technicians are qualified to handle furnace repairs safely and effectively. In Tennessee, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Look into a furnace repair company's qualifications and experience. Your provider should employ well-trained technicians who have experience working with various furnace makes and models. Ask about a company's training policies to make sure they're up to date on industry standard repair techniques.
  • Reputation and reviews: Read online reviews and testimonials to get a sense of a company's reputation. It's important to look for a provider with overall positive reviews, but you should also pay attention to how it addresses negative feedback. This can tell you a great deal about a company's commitment to customer service.
