Types of Furnaces & Longevity

The lifespan of a furnace depends on a few different factors, including the type of furnace, quality of the installation, and if regular maintenance takes place. Regular maintenance, including annual inspections and cleaning, can help extend the lifespan of your furnace.

There are several types of furnaces available, each with their own unique benefits and drawbacks. The most common types that you should consider for your home or business include gas, electric, and oil.

Our Process

Furnace Replacement Process

The process of replacing a furnace is complex and requires the expertise of a professional, such as those at Lindemann. We’ll help you choose the right furnace, ensure proper installation, and provide ongoing maintenance to keep your furnace working efficiently for the long term. Here are the steps involved in replacing your system:

  1. Initial consultation: The process typically starts with an initial consultation with one of our furnace installation professionals. During this consultation, the technician will assess your home’s heating needs and recommend the best type and size of furnace for your home.
  2. Removing the old unit: Once the new furnace has been selected, the old furnace will need to be removed. This may involve shutting off the power and gas supply to the furnace, disconnecting the furnace from the ductwork, and removing the furnace from the home.
  3. Preparing the installation site: The installation site will need to be prepared before the new furnace can be installed. This could involve installing new ductwork, electrical wiring, or gas lines, depending on the type of furnace being installed.
  4. Installing the new system: Once the installation site is ready, the new furnace can be installed. This typically involves mounting the new unit on a platform or stand, connecting it to the ductwork, electrical wiring, and gas supply, and testing the new system to ensure it is working properly.
  5. Adjusting the thermostat: The thermostat will need to be adjusted to ensure it is compatible with the new furnace and is properly calibrated to maintain a comfortable temperature in the home.
  6. Final inspection: Once the furnace has been installed, a professional will typically conduct a final inspection to ensure the furnace is functioning properly and that all safety protocols have been followed.

Your Warranty

Warranty Coverage

Furnaces typically come with a warranty, which can vary depending on the manufacturer and the model. The warranty typically covers parts and labor for a certain period of time, and it may also cover additional costs such as the cost of replacement parts or labor. It’s important to check the warranty coverage before purchasing a new furnace, and also to keep the warranty documentation and sales receipt in a safe place.
