Services Offered by Furnace Repair Companies

Furnace repair companies offer various services to keep your furnace working effectively and efficiently. We go over some common services below.

Repair and Maintenance

Timely repairs not only restore your furnace's function, they also extend its lifespan and optimize energy efficiency. Furnace repair providers can diagnose and repair any furnace issue, such as a clogged air filter, malfunctioning thermostat, or broken blower motor. Qualified HVAC technicians examine and fix individual problems like damaged heat exchangers, malfunctioning thermostats, faulty ignitions, or possible gas leaks. Furnace repair technicians can also handle routine HVAC maintenance to avoid unnecessary breakdowns. This might involve inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring all components function optimally.


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


If you notice your furnace isn’t turning on, your furnace repair company will likely recommend a thorough inspection to identify possible problems. This will involve a technician examining each of the furnace's components. The inspection typically includes testing the thermostat's accuracy, cleaning and replacing air filters, inspecting the burner and ignition system, checking for any gas or fuel leaks, and examining the heat exchanger for cracks or damage. A technician will check the heating system's efficiency and safety and make any necessary repairs or adjustments. Annual furnace tune-ups encourage optimal performance and help avoid potential breakdowns, which promotes a safe living environment during colder months.

Emergency Services

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

Factors To Consider When Choosing a Local Largo Furnace Repair Service

You should consider several factors when hiring a local Largo furnace repair provider. We review some key considerations below.

  • Cost: Compare pricing and services offered by several Largo furnace repair companies. Look for transparent and competitive pricing, but avoid extremely low-cost options. Abnormally low prices may indicate that a company is making up the difference by compromising the quality of work or materials.
  • Guarantees: Ask your furnace repair company about any warranties or guarantees it offers. Reliable service providers offer these guarantees to protect customers in case of any issues post-repair. Guarantees can cover both parts and workmanship.
  • Licensing: You want to use a furnace repair provider that holds all the appropriate licenses and certifications. HVAC contractors in Florida may have either a certified contractor license (C) or a registered contractor license (R). Both are handled by the Florida Department of Business and Professional Regulation. Proper licensing helps ensure that technicians are qualified to safely handle furnace repairs.
  • Qualifications: Ask about the experience and qualifications of a furnace repair company. You want technicians that are well-trained and experienced at working with various furnace makes and models. Inquire about a company's training programs to verify that technicians are up to date on current industry standards for repairs.
  • Reputation and reviews: Learn more about a company's reputation by looking at online reviews and testimonials from previous customers. A strong positive reputation is a good indicator of quality services. Look at how the provider addresses negative feedback or complaints, reflecting its commitment to customer satisfaction.

How Much Does a Furnace Repair Cost?

The total cost of furnace repair varies depending on factors including the type of HVAC unit, the extent of the damage, and the cost of replacement parts. The final total may vary, but on average expect to spend around $407 on furnace repair. Below, find a list of common repairs and their costs.
