Furnace Repairs, Cleaning, Replacement and Installation Services

Is your furnace making loud noises when you turn it on? Is it not cooling your house enough on a hot summer day? Your furnace breaking down is the last thing you need in the middle of winter. These are signs your furnace needs repair:

  • Lack of heat
  • On and off cycling
  • Strange noises
  • Fluid leaking

Stay ahead of the cold with our repair and cleaning services. Our technicians inspect your unit and address any issues, all on the same day! With years of experience, there are no furnace issues too complex for us to handle.

Furnaces we install

There comes a time when your furnace will reach the end of its life. If your unit is struggling to keep your home warm, it is time for a replacement! At the Thielmann Heating, Cooling, & Plumbing, we specialize in installing the best furnaces for homes in Mequon, WI. We install the following furnaces:

  • Gas – Popular choice for energy efficiency and cost-effectiveness. 
  • Oil – Effective alternative if you don’t have natural gas. More frequent maintenance is balanced by stronger heat output.
  • Electric – Simple and efficient, providing a longer life span without as much maintenance. Simplicity comes with higher operating costs.

Heat Pump System Repair, Installation and replacement Services

Heat pumps are great alternatives to furnaces. They provide both heating and cooling capabilities with more precise control. Heat pumps act as a flexible alternative to furnaces. The units allow for dual systems for consistent heating and cooling. They offer all-year comfort while being energy-efficient. Over time, however, your system may show some signs warranting a repair:

  • System limited to only heating or cooling
  • Heating or cooling slowly
  • Sparking or smoking from the unit 

While common, these issues leave your heat pump needing to be more efficient. Our experts are available for same-day appointments. We offer comprehensive repairs for all heat pump problems. 

When is it time to replace your pump?

If you currently own a heat pump, look for signs that it needs a replacement. The signs include the following:

  • Frequent repairs 
  • Energy bill increases
  • Inconsistency in the heating and cooling

Our heat pump installations are quick and efficient, meaning you can get back to home comfort faster.
