During each of our legendary winter cold snaps our techs arrive at least a few service call where the problem could have been resolved by the owner. Perhaps you'll save stress, time, and money by checking these things before you call:

  • Make sure your thermostat is "ON", is set to "HEAT", and the desired room temperature is set higher than the current ambient temperature.

  • Check you circuit breaker panel to ensure that your heating system breaker is "ON".

  • Make sure your "FURNACE SWITCH" is set to "ON". This switch is typically a traditional toggle switch that may have a RED cover-plate.

  • Change your furnace filter and re-start your furnace.

An unexpected furnace breakdown will leave you in a very unpleasant situation. Luckily, you can reduce the chances of furnace malfunction with regular furnace maintenance performed by a qualified technician. Like most systems that operate on a regular basis, your furnace can benefit from being looked over and tuned up by a professional who knows what they are doing.

  • Better Efficiency A professional tune-up for your system will keep it operating efficiently, and greater efficiency means smaller energy bills as well as a longer system lifespan.

  • Protection Against Unexpected Breakdowns Our technicians will find weak points during maintenance, so solutions can be provided now. This reduces the chances of these small issues resulting in surprise breakdowns during the freezing temperatures and the associated headache of getting expensive emergency repairs.

  • Protect Your Furnace Warranty: All manufacturers require routine inspection and maintenance. Proper maintenance will ensure that your system and your warranty is in great shape.

  • Extended Service Life: A properly maintained furnace will have a longer service life.

Call us before the heating season and we’ll perform a thorough furnace cleaning and check. We’ll change your furnace filters, clean up and accumulate dust or debris, check your furnace vents, then run test your system to ensure you’re ready for a winter of safe and reliable heating.
