Same-Day Cooling Repair

A working AC is essential during Wisconsin’s hot and humid summer days. Our team understands the necessity of quick repairs if your system malfunctions for central air conditioning units, ductless mini-splits, and heat pumps. Some signs that your system might need immediate repair include:
  • Loud noises or strange smells
  • Leaking or puddling water
  • Warm air from the vents
  • Blown fuses or tripped breakers
  • Increased energy bills
  • Inconsistent temperatures in your home
  • Frequent short-cycling

Quality AC Installation & Replacement Services

Sometimes, an air conditioner has seen better days and needs to be replaced. At The Thielmann Group, our team has the expertise for installation and familiarity with the latest brands in the industry. We can replace your central AC, ductless mini-split, or heat pump. It may be time for your AC to be replaced if:
  • Poor performance: It may go without saying, but if your AC isn’t cooling down your home, it’s likely time to install a new one. Be sure to handle this as quickly as possible instead of suffering through hot days in the middle of summer.
  • Age of unit: On average, air conditioners last between 10 to 15 years. Call us if yours is within this range and is giving you trouble.
  • Frequency of repairs: If you feel that you’ve been calling for repairs all too frequently, this is another sign that your AC may be on the fritz.
If it’s time for a new air conditioning unit, call us at (262) 299-6197 or contact us online.

Preventative Air Conditioning Maintenance

Routine AC maintenance will help extend your unit’s life span and prevent frequent or costly repairs. Regularly tuning up your system will also improve its efficiency, saving you money on your energy bills. It’s recommended to have your air conditioner professionally maintained once a year before the cooling season begins. You can do simpler tasks, like replacing the air filter or ensuring the area around your system is debris-free, but it’s best to have a qualified HVAC technician complete more significant tasks. This will ensure your system works at peak performance throughout the season. To schedule AC maintenance with the Thielmann Group, call us at (262) 299-6197 today!

AC FAQs

There are several advantages to installing a ductless mini-split, including:
  • Increased energy efficiency
  • Less noisy than traditional AC
  • No ductwork required
  • Can be installed in different rooms
  • Easy to maintain
  • Environmentally friendly
A packaged HVAC unit contains all components, including the condenser, evaporator, and air handler, in a single unit, making it a good option for homes and businesses with limited space. Though these systems are more expensive than traditional units, they are typically quieter, more energy-efficient, and easier to install.

I've been using Thielmann Group for all my heating and air conditioning since I built my house 23 years ago. They have been great in emergency service and regular maintenance service. On time and very friendly staff. Would, and have, recommend them to anyone!

The Thielmann group team was professional, knowledgeable, and on time. They did a fantastic job at a reasonable price. From our first encounter, we could understand how experienced the group was. There were no issues, and the new furnace worked perfectly. I highly recommend them.
