EACH YEAR THERE ARE ATLEAST 15,000 DRYER FIRES THAT DESTROY HOUSES AND LIVES. THE DRYER VENT SYSTEM IS THE MOST NEGLECTED SYSTEM IN THE HOUSE. IT IS A SYSTEM THAT IS NOT BE TAKEN AS A JOKE.IT IS JUST AS IMPORTANT TO CLEAN AS YOUR AC DUCTS. THE LINT BUILD UP WILL CAUSE A BLOCKING IN THE PIPE AND IT WILL ONLY TAKE THAT ONE REACTION SPARK TO START THE FIRE. IT WILL TRAVEL UP THE PIPE THRU THE ATTIC SET THE ATTIC INSULATION ON FIRE, AT THAT POINT CALL 911 AND GET YOUR PERSONNEL BELONGINGS OUT. ATLEAST ONCE A YEAR YOU SHOULD HAVE IT CLEANED AND REPLACE ANY PARTS THAT ARE FAULTY OR HAVE SEEN BETTER DAYS. THERE ARE 3 DRYER VENT HOSES THAT HAVE BEEN DISCOUNTINUED. THE COMMON ONE HERE IN ARIZONA WAS THE ALL PLASTIC ONE TO WHICH I AM STILL REPLACING. THEY WENT TO A FOIL WRAP ON THE OUTSIDE BUT PUT A BLACK OR WHITE PLASTIC LINER ON THE INSIDE. THESE HOSES ARE A FIRE HAZZARD SINCE PLASTIC AND HEAT DO NOT MIX WELL TOGETHER. WE AT MIKE'S DRYER VENT ONLY USE REPLACEMENT PARTS THAT ARE UL LISTED APPROVED. IF IT DOES NOT HAVE THAT LOGO SEAL ON THE PACKAGE YOU WILL NOT FIND IT ON OUR TRUCK OR INSTALLED IN YOUR HOME. FOR EACH JOB WE DO THAT IS 1 MORE HOUSE SAVED. SO DON'T DELAY IT ANY FURTHER GET IT DONE NOW. CONTACT MIKE'S DRYER VENT OF PHOENIX ARIZONA TODAY. HOPE TO HERE FROM YOU SOON. MIKE
