Heating

No heat, short cycling, odd smells or noises. We find the cause and fix it, or install a right-sized high-efficiency furnace or heat pump.

  • Furnace and boiler repair
  • Heat pump install and service
  • Blower motor replacement

Cooling

Warm air, frozen coils, refrigerant leaks, failed capacitors. We get you cool again, and size new systems with a load calculation instead of a guess.

  • A/C repair
  • Central A/C and ductless installs
  • Condenser fan motors

Weatherization

Drafty rooms and high bills usually come from air leaks and thin insulation. We seal the leaks, then insulate, then test so the house stays safe.

  • Air sealing in the attic, rim joists and penetrations
  • Attic, wall and crawlspace insulation
  • Duct sealing and weatherstripping

Qualifying Ameren Illinois customers may get this at little to no cost.

Ducts and airflow

Leaky or disconnected ducts can lose a big share of what your system makes. We clean, seal and repair them so air ends up in the rooms.
