Services Offered by Furnace Repair Companies

Local furnace repair providers offer various services to ensure your furnace runs efficiently. We review common services below.

Repair and Maintenance

Timely professional repairs restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair companies can diagnose and repair a number of issues, including broken blower motors, malfunctioning thermostats, and clogged air filters. Qualified HVAC technicians also have the expertise to tackle problems like malfunctioning thermostats, faulty ignitions, damaged heat exchangers, and possible gas leaks. Furnace repair professionals can also handle a routine HVAC system tune-up to avoid unnecessary breakdowns. This can involve inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring all components function optimally.

Installation

HVAC companies can help you mount a new furnace if yours is past repair. An expert can also help you upgrade to a more energy-efficient model, such as a heat pump. First, a skilled technician will assess your heating needs and home’s layout. Then, the tech will recommend the best furnace model for you based on your requirements and budget. Your HVAC installer can integrate your new system with your existing air ducts and thermostat. They're trained on industry standards and safety protocol for proper exchange of the existing furnace and connection. Following installation, the technician will perform one last inspection to make sure your furnace runs efficiently.

Inspection

Schedule an inspection with a furnace repair company if you notice your furnace failing to turn on. During the inspection, a technician will look at every component of your furnace to identify possible issues. The inspection usually includes checking for any gas or fuel leaks, inspecting the burner and ignition system, cleaning and replacing air filters, examining the heat exchanger for cracks or damage, and testing the thermostat's accuracy. Your technician will verify the heating system's efficiency and safety while making the necessary repairs or adjustments. Regular yearly furnace tune-ups facilitate optimal performance, help prevent potential breakdowns, and promote a safe living environment during cold winters.

Emergency Services

Emergency furnace repair services can help with unexpected breakdowns, malfunctions, or other safety concerns. Many companies offer these around-the-clock services to help get your system back up and running promptly. Furnace failure can cause discomfort and serious health risks from the reduced indoor air quality, especially if the breakdown happens during extreme weather and you're unable to open windows for fresh air. Emergency services may cost more than scheduled services, but it's worth it to protect your health.

Factors To Consider When Choosing a Local St. Charles Furnace Repair Service

There are a number of important considerations for choosing a local St. Charles furnace repair company. We’ve detailed them below.

  • Cost: We recommend comparing several St. Charles furnace repair providers to look for the best service offerings and prices. Look for competitive, transparent pricing, but be wary of companies that quote extremely low rates. These providers may make up the difference with subpar replacement parts or low-quality workmanship.
  • Guarantees: Reputable furnace repair companies should provide warranties or guarantees on their parts and workmanship. Companies that back their work this way offer you peace of mind if something goes wrong post-repair.
  • Licensing: Confirm that your furnace repair servicer holds all necessary licenses and certifications. This ensures that the technicians are qualified to handle furnace repairs safely and effectively. In Missouri, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Find out what experience and qualifications a furnace repair company has. A company should employ well-trained technicians who have experience with various furnace makes and models. Ask about a company's training policies to ensure they're up to date on industry standard repair techniques.
  • Reputation and reviews: Check online testimonials and reviews to get a sense of 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 great deal about a provider's commitment to customer service.
