Services Offered by Furnace Repair Companies

You can hire a local furnace repair company for a number of services that help keep your furnace running efficiently. We’ve outlined the most common ones below.

Repair and Maintenance

Timely repairs restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair experts are trained to deal with broken blower motors, clogged air filters, malfunctioning thermostats, and more. Your technician can help diagnose and repair problems like these to keep your furnace working effectively. A qualified HVAC technician can also assist with issues such as malfunctioning thermostats, damaged heat exchangers, faulty ignitions, or possible gas leaks. Your furnace repair provider can also perform routine HVAC system upkeep to help avoid unnecessary breakdowns. Your technician will ensure that all components function properly by inspecting and cleaning your furnace, lubricating moving parts, and replacing air filters.

Installation

Your local HVAC expert can upgrade your furnace to a more energy-efficient model, such as 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 budget and home requirements. Your HVAC professional can integrate your new system with existing air ducts and thermostats. They're trained on industry safety protocols and standards to ensure proper furnace replacement and connection. To ensure everything runs optimally, your technician will perform a final inspection following installation.

Inspection

Schedule an inspection with a furnace repair provider if you notice your furnace failing to turn on. A technician will inspect each of the furnace's components to identify potential problems. The inspection typically includes examining the heat exchanger for cracks or damage, inspecting the burner and ignition system, testing the thermostat's accuracy, cleaning and replacing air filters, and checking for any gas or fuel leaks. Yearly inspections of this type encourage optimal heating system performance, help avoid breakdowns, and promote safe living during cold winters. A technician will verify your system's efficiency and safety and make any needed repairs.

Emergency Services

Emergency furnace repair services help with unexpected breakdowns, malfunctions, or other safety concerns. Many providers offer these 24/7 services to help get your system up and running promptly outside of normal business hours. 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 from decreased indoor air quality, especially if it breaks down during extreme weather conditions when you're unable to open windows for fresh air.

Factors To Consider When Choosing a Local Crystal Lake Furnace Repair Service

You have a number of factors to consider when hiring a local Crystal Lake 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. We recommend comparing several Crystal Lake furnace repair companies. Avoid ones that offer extremely low rates, as many employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Trustworthy furnace repair companies should provide guarantees or warranties on their workmanship and parts. Companies that stand behind their work 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. It's important to hire a furnace repair provider that is properly licensed and certified to ensure that your technician is trained and qualified to handle furnace repairs safely and effectively.
  • Qualifications: Learn about the experience and qualifications of a furnace repair company. You want technicians that are well-trained and experienced at working on various furnace makes and models. Ask about company training programs to confirm that technicians are educated on the latest industry standards.
  • Reputation and reviews: Read online testimonials and reviews from previous customers to get a sense of a company's reputation. Look for a provider with overall positive reviews, but also be mindful of how it addresses negative reviews and complaints. This can tell you a lot about a company's commitment to customer service.
