Services Offered by Furnace Repair Companies

You can hire a local furnace repair provider for a number of services that help your furnace run efficiently. We outline some common offerings below.

Repair and Maintenance

Professional and timely repairs will restore your furnace's function, extend its life span, and optimize energy efficiency. Your furnace repair provider can diagnose and repair a number of issues, such as broken blower motors, malfunctioning thermostats, and clogged air filters. Qualified HVAC technicians also have the expertise to tackle problems such as faulty ignitions, malfunctioning thermostats, damaged heat exchangers, and possible gas leaks. Furnace experts can also perform 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

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, such as a heat pump. First, skilled technicians assess your home's layout and heating needs. Then, they recommend a suitable furnace model based on your budget and home requirements. Your HVAC expert can integrate your new system with your existing air ducts and thermostat, and they should follow industry standards and safety protocol for proper exchange of the existing furnace and connection. Post-installation, the technician will perform a final inspection to make sure your furnace runs efficiently.

Inspection

You likely need an inspection if you discover that your furnace isn’t turning on. During this inspection, a technician will examine each part of the furnace to look for potential causes. Inspections usually include cleaning and replacing air filters, checking for any gas or fuel leaks, inspecting the burner and ignition system, examining the heat exchanger for cracks or damage, and testing the thermostat's accuracy. Your technician will verify the heating system's safety and efficiency while making the necessary repairs or adjustments. Routine, annual furnace tune-ups facilitate optimal performance, help avoid potential breakdowns, and promote safe living during cold winters.

Emergency Services

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

Factors To Consider When Choosing a Local Dover Furnace Repair Service

There are a number of important considerations to keep in mind when selecting a local Dover furnace repair provider. We review some key factors below.

  • Cost: Look for a company that provides all the services you need, and that offers transparent and competitive pricing. We recommend comparing multiple Dover furnace repair companies. Beware of ones with extremely low rates, as they may employ low-quality workmanship or subpar replacement parts.
  • Guarantees: Warranties and guarantees provide peace of mind in case problems come up post-repair. Trustworthy furnace repair companies should back their work with warranties or guarantees for both workmanship and any replacement parts.
  • Licensing: Make sure that your furnace repair company possesses all required licenses and certifications. This ensures that its technicians are qualified to handle furnace repairs safely and effectively. HVAC contractors in Delaware may have either a Master HVACR license or a Master HVACR Restricted license, both issued by the Delaware Division of Professional Regulation.
  • Qualifications: Find out what experience and qualifications a furnace repair company has. Your service provider should employ well-trained technicians who have experience working 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: Look through online reviews and testimonials to learn about a company's reputation. Look for a provider with overall positive reviews, but also pay attention to how it addresses negative feedback. This can tell you a lot about a provider's commitment to customer service.

How Much Does a Furnace Repair Cost?

Several factors affect the price of your furnace repair project. These include the type of HVAC unit, extent of the damage, and price of replacement parts. Furnace repair costs $428 on average, though prices vary depending on the details. The following are some common furnace repairs, as well as their average costs.

  • Broken thermostat: $79–$397
  • Cleaning: $48–$63
  • Cracked heat exchanger: $1,587–$2,778
  • Damaged blower bearings: $24–$119
  • Damaged blower belt: $24–$87
  • Filter change: $32–$119
