Fairfax Generator Services

Reliable Backup Power for Your Home

Backup generators offer comfort and convenience for your family when the power goes out. Severe weather often results in power failures, leaving families to suffer in the extreme cold or heat. A whole house generator restores the electricity to your home until the power comes back on. Air Treatment Company offers comprehensive generator services in Fairfax County and beyond.

Quality Kohler Generators

We have chosen to offer Kohler generators for the quality, value, and comfort they provide for our customers. These whole house generators sense when the power levels drop and automatically switch on. When the power is restored, the generator will shut down and switch your home back to the utility electrical power, so your comfort and convenience are never interrupted.

Kohler whole house generators are:

  • Extensively tested for quality and reliability
  • A source of clean, quality power for your electronics
  • Available in a range of sizes to power every home
  • Covered by a 5-year warranty
  • Trusted by hospitals, power plants, and the National Weather Service

Kohler generators are available in models specifically designed for residential electrical power backup and run on a variety of fuels. We offer honest, expert advice about the generator that will best fit your needs. After you have selected your generator, our technicians provide professional installation, connecting the generator to your main panel to provide backup power for your whole house.

Generator Maintenance

Preventative maintenance ensures that your generator is ready for any power outage. We offer annual inspections to make sure your generator is operating as it should. This service includes changing oil, oil filters, and fuel filters. We check coolant levels, the control panel, engine safety controls, air intake and exhaust systems, and other components of generators.

When it comes to generator services in Fairfax, we are simply the best. Let us help you install, maintain, and repair your generator!
