Signs You May Need a Need Furnace

In Southeast Wisconsin, where winters are brutal, ensuring your furnace works correctly is paramount.

Signs that you may need to replace your furnace include:
  • Your furnace starts making unusual noises like banging, whistling, or groaning.
  • Some rooms are too cold while others are too warm, or the furnace struggles to maintain a stable temperature.
  • There’s a sudden spike in your heating bills.
  • Your furnace turns on and off more frequently than usual, called short-cycling.
  • In gas furnaces, your pilot light is yellow or flickering instead of producing a blue flame.
  • Your home’s air quality is worse than before.
  • Your furnace is over 15 to 20 years old.
  • Your furnace doesn’t start right away or at all.
  • Odors are coming from your furnace.
If you notice any of these signs, it’s essential to contact a professional for furnace repair or replacement, especially in the colder months when heating is necessary for comfort and safety. Regular maintenance can also help prevent some of these issues.

Types of Furnaces We Install

At The Thielmann Group, we specialize in providing top-notch furnace installation services in Southeast Wisconsin, catering to each homeowner’s needs. Our services include installing gas and oil furnaces, each with unique benefits.

  • Gas furnaces: Known for their efficiency and cost-effectiveness, they are a popular choice. They provide reliable and consistent heating and are typically more energy-efficient, which can lead to lower utility bills.
  • Electric furnaces: These units are simple, efficient, and have lower initial installation costs than gas furnaces. Electric furnaces have a longer life span and require less maintenance than gas furnaces, but their operating costs can be higher.
  • Oil furnaces: Ideal for areas where natural gas isn’t readily available, oil furnaces are an effective alternative. They are known for their durability and ability to produce more heat per BTU, although they might require more frequent maintenance.
With a legacy of quality service since 1929, Thielmann Heating ensures each installation is handled with the utmost professionalism and attention to detail, ensuring your home stays warm and comfortable through the chilly Wisconsin winters.

Is your gas or oil furnace not working the way it should? Contact The Thielmann Group at (262) 299-6197 in Southeast Wisconsin to schedule your furnace replacement.

Benefits of Installing a New Furnace

While swapping out your old furnace for a new one doesn’t sound exciting, it will have benefits that you’ll be able to enjoy immediately, such as:
  • Improved efficiency and cost savings: New furnaces are more energy-efficient than old ones.
  • Better indoor air quality and less dust: They also help regulate humidity levels, which can help prevent mold and mildew growth.
  • Increased home comfort and convenience: Smart thermostats make setting up zones in your home easier, and you can operate your thermostat from your phone.
  • Higher property value and resale appeal: Energy-efficient heating systems attract prospective buyers and can be a significant selling point.
  • Environmental benefits: Installing a new, energy-efficient furnace reduces your carbon footprint and minimizes the ecological impact.
  • Fewer repairs and maintenance: As long as your furnace is serviced yearly, it can last for years without significant issues.
