What To Do When Your Heat, AC Or Plumbing Fails In Shiawassee County

Find what is happening at your place, the first thing to do about it, and the service that fixes it. Our phone is answered at any hour.

  1. No heat, or the furnace keeps shutting off

    Check the thermostat batteries and the furnace filter first, because a clogged filter can shut a furnace down. If it still won't run, call us, day or night.

    Furnace repair in Novi →Call any hour
  2. Water in the basement, or the sump pump won't run

    Make sure the sump pump is plugged in and its breaker hasn't tripped, then pour a bucket of water into the pit to see if it starts. If the water is still rising, call now.

    Sump pump repair →Call any hour
  3. A leaking water heater, or no hot water

    If the water heater is leaking, close the cold water valve on the pipe above it and turn the gas knob to off, or switch off its breaker if it's electric. A leak from the tank itself means a replacement, and that estimate is free.

    Water heater repair in Novi →Call any hour
  4. The air conditioner runs but the house won't cool

    Change the filter, then look at the copper line going into the outdoor unit. If it's iced over, set the thermostat from cool to off and the fan to on, so the ice melts before we get there.

    Air conditioner repair in Novi →Call or book online
  5. Drains backing up in more than one place

    Stop running water in the house. When a toilet and a tub or floor drain back up together, it's usually the main sewer line rather than one drain.

    Drain cleaning in Novi →Call any hour
  6. An old furnace or air conditioner with repair bills adding up

    Look for the manufacture date on the label inside the furnace door or on the outdoor unit. Past about 15 years with a major part failing, price a replacement next to the repair. We quote both, and the replacement estimate is free.

    Furnace replacement →Air conditioner replacement →Free estimate

Smell gas? Get everyone out of the house first, then call 911 or your gas company from outside.

I noticed that my furnace was not working around 3pm.  I called and a service person was there a little after 4 and took less than an hour to fix it.  I am very happy with the service.
