The Right Safety Equipment

You and your family deserve to be safe at home. That’s why L&L Heating and Air Conditioning provides a variety of safety equipment to test for high levels of toxins like carbon monoxide. Talk to our team to learn what would help make your home safer.

L&L HVAC will help you protect your home with new technology from Carbon Monoxide detectors, Water Leaks and Freeze detectors, and Home Door Video Cameras to know who is coming to your home.

Carbon Monoxide Protection

Carbon monoxide (CO), an odorless, colorless gas, which can cause sudden illness and death, is produced any time a fossil fuel is burned. CDC works with national, state, local, and other partners to raise awareness about CO poisoning and to monitor CO-related illness and death in the U.S.

You Can Prevent Carbon Monoxide Exposure.

  • Do have your heating system, water heater and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
  • Do install a battery-operated or battery back-up CO detector in your home. Check or replace the battery when you change the time on your clocks each spring and fall. If the detector sounds leave your home immediately and call 911.
  • Do seek prompt medical help if you suspect CO poisoning and are feeling dizzy, light-headed, or nauseated.
  • Don’t use a generator, charcoal grill, camp stove, or other gasoline or charcoal-burning device inside your home, basement, or garage or near a window.
  • Don’t run a car or truck inside a garage attached to your house, even if you leave the door open.
  • Don’t burn anything in a stove or fireplace that isn’t vented.
  • Don’t heat your house with a gas oven.
  • Don’t use a generator, pressure washer, or any gasoline-powered engine less than 20 feet from any window, door, or vent. Use an extension cord that is more than 20 feet long to keep the generator at a safe distance.
