Residential Products, Services

ACG, Advanced Custom Geothermal, is a full-service HVAC contractor. Look to us for your residential heating, ventilating and air conditioning solutions.

Here are the products and services we offer:

  • Design, consulting and inspection services for residential geothermal systems. We can specify complete systems so you can solicit bids for your new residential geothermal system. In addition, we offer consulting and inspection services for existing or new residential geothermal installations.
  • Geothermal. We offer it for forced-air systems and hot water as well as for in-floor radiant heat. Geothermal can be installed in both new and retrofit situations.
  • Conventional gas and oil furnaces and boilers. We install conventional forced-air systems, hot water baseboard systems and radiant floor heating systems. For hydronic or hot water heat, we sell and service WaterFurnace, Crown Boilers, Utica Boilers, Triangle Tune and Watts Radiant. For gas and oil furnaces, we sell, install and service Rheem heating and cooling products.
  • Air conditioning systems. Don’t suffer through another hot, muggy Wisconsin summer. We’ve got options besides the cool comfort of geothermal. We offer conventional air-conditioning systems and split systems, such as the Panasonic brand, for homes with baseboard heating or without ductwork. For added comfort, we can install Hi-Velocity mini-duct systems.
  • Air-to-air exchangers. Homes today may be so well insulated that they trap humidity and pollutants indoors. But you can breathe the same fresh air indoors as you do outdoors. Contact ACG today about the Venmar line of Indoor Air Quality products. A Venmar air exchanger will eliminate a range of humidity and condensation problems.
  • Gas fireplaces. If you are looking for traditional or contemporary styling in a gas fireplace, we offer Empire products. These fireplace products bring comfort and ambiance to that special room.
  • Humidifiers, duct cleaning, UV light air purifiers. ACG offers these other residential products and services as well to keep your home clean and comfortable for you. Please contact us for details.
