We are always available by phone 24/7 for emergency service (temporarily unavailable)!  Please call 207-743-0911 for assistance.  If we are busy and unable to answer your call, please leave us a message and we will return your call as soon as possible, which may be the next business day.

If you find that there is a leak or any issues with your heating system (heat and/or hot water), please call us immediately.  If you wait too long, the leak or issue could cause a bigger problem and be more costly.  Also, if the unit is still under warranty, you want the issue taken care of right away because if you let the issue continue, the manufacturer may not warranty if the upkeep on the unit was not maintained.  

If you are a handy person and want to do work on your own heating system/water heater, be advised that if the unit is still under warranty, the warranty may be void if the work is not performed by a licensed professional.

Have no heat/hot water????  Here are a few things for you to check that may save you a service call:

*Is the emergency switch turned on?  There should be two switches.  One on the furnace/boiler and one in the stairway or outside the room where the furnace/boiler is located.  Many mobile homes only have the emergency switch by the back door, close to the furnace.

*If you are having hot water issues in just your shower, you may need to contact a plumber as the mixing valve may be bad.  If you are having hot water issues in the entire home, please give us a call.

*Do you have oil/propane in the tank?  *If your oil tank is an outside tank, make sure that the filter canister is not frozen.  Placing a heat tape around the filter canister will assist in keeping the canister/filter from freezing.

*Check the house fuses/circuit breakers to make sure nothing has tripped

*Make certain that all furnace venting is clear (roof vent cleared of any obstructions, direct vent from side of house cleared of any blockages).  If you snow blow, aim the shoot away from any side venting you have for your heating system.  The smallest amount of snow can cause condensation and cause the heating system not to run.  If the heating system cannot properly vent the fumes, the fumes could end up back into the home.

*If a Miller furnace, make certain the door is shut tightly

*DO NOT push the reset button more than once as the oil will build up in the chamber and could cause more problems.

If after checking the above and you still have no heat/hot water, do not hesitate to call us!  207-743-0911

With the mouse nests that we have been finding in the A/C condensors this year, we suggest that you get your A/C unit cleaned and tested.   Spring is the best time to get your A/C system checked so you are ready for Summer.
