    Automotive Repairs
    Given that the average cost to hire a tow truck service may amount up to something between $75 and $125, what should YOU do when your car does not start? For some, a minimum charge of $50 for the first 5 to 10 miles, then $2 to $4 per mile after may not be a problem… But what about a DIY...

  3. Lennox G20Q3E pilot & burners sporadically won't light

    HVAC
    Hi guys. A few days ago I noticed my Lennox G20Q3E-75-6 (1997 model) was not putting out hot air. Upon further inspection, it was evident the pilot light was not lighting. After some fiddling around, I determined that one works-most-of-the-time workaround was to turn the gas valve switch on...

    Summary: Where should the spark be to properly ignite? My house has a Natural Gas "Concord 80 Plus" furnace... The ignition stopped working recently, so I've been attempting to fix it it [as safely as I can]. (I always shut the electricity and gas off before touching anything). Anyway, It's...

    I have a 12 year old Comfortmaker gas furnace. It operated fine all last winter. When I went to fire it up the first time today, only 4 of the 5 burners light off (burners 2 thru 5 when counting from where the gas enters the manifold). The ignitor is in front of burner 5, the ignition sensor...

  9. Lennox Conservator II Won't Stay Lit

    HVAC
    I have a Lennox Conservator II. Last year it started having problems with the ignition. This was exacerbated by the fact that the flame will only burn for a couple minutes and then shut off. Even when you are nowhere near the desired temperature. Then it has to try to re-light itself. You...
  10. Gas Furnace will not stay lit...
