Services Offered by Furnace Repair Companies

Furnace repair providers offer a number of services to keep your furnace working at maximum efficiency. We review common services below.

Repair and Maintenance

Timely repairs help extend your furnace's life span and optimize its energy efficiency, in addition to restoring function. Furnace repair professionals can diagnose and repair any furnace issue, such as a malfunctioning thermostat, clogged air filter, or broken blower motor. Qualified HVAC technicians examine and fix individual problems such as damaged heat exchangers, faulty ignitions, malfunctioning thermostats, or possible gas leaks. Furnace experts can also complete routine HVAC maintenance to avoid unnecessary breakdowns. Regular maintenance involves inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and making sure all components function correctly.

Installation

Your HVAC provider can help you upgrade your furnace to a more energy-efficient model, such as a heat pump. If your system is past repair, they can also help install a new furnace. Your technician will begin by assessing your heating needs and home’s layout. Then, the tech will recommend the right furnace model for your requirements and budget. HVAC technicians follow industry standards and safety protocols to ensure safe furnace replacement and connection. They also integrate a new system with your existing air ducts and thermostats. Following installation, the company will complete one last inspection to confirm that the furnace runs optimally and efficiently.

Inspection

If your furnace isn’t turning on, you should schedule a thorough inspection through a furnace repair provider. A technician will examine each component of your furnace to look for potential causes. The inspection typically includes 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. We recommend an annual inspection, during which your technician will verify your heating system's efficiency and safety and make any necessary repairs or adjustments. Regular tune-ups help prevent potential breakdowns, ensure optimal heating performance, and promote a safe living environment during chilly winters.

Emergency Services

Emergency furnace repair services help with unexpected breakdowns, malfunctions, or safety concerns. Many companies offer these 24/7 services to help get your system back up and running promptly any time of the day or night. Emergency services can cost more than a scheduled service, but protecting your health is worth it. Furnace failure can cause discomfort and serious health risks due to reduced indoor air quality, especially if the breakdown happens during extreme weather conditions when you can't open windows for fresh air.

Factors To Consider When Choosing a Local DeKalb Furnace Repair Service

You have a number of factors to consider when selecting a local DeKalb furnace repair service. We go over some of the most important below.

  • Cost: Look for transparent and competitive pricing, and make sure you find a company that offers all the services you need. We recommend comparing several DeKalb furnace repair providers. Beware of ones that offer extremely low rates, as they may employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Trustworthy furnace repair companies should offer guarantees or warranties on their workmanship and parts. Companies that back their work this way offer you peace of mind if something goes wrong post-repair.
  • Licensing: In Illinois, your HVAC contractor must obtain certification from your local city or municipal government. Hiring a properly licensed and certified furnace repair provider is essential to ensure that your technician is qualified to handle furnace repairs safely and effectively.
  • Qualifications: Look into a furnace repair company's qualifications and experience. Your service provider should employ technicians that are well-trained and have experience working with various furnace makes and models. You can inquire about a company's training policies to make sure they stay on top of the latest industry standard repair techniques.
  • Reputation and reviews: Look through online testimonials and reviews to learn about a company's reputation. Look for a provider with overall positive reviews, but also pay attention to how it addresses negative reviews and complaints. This can reveal a lot about a company's commitment to customer service.
