Furnace Tune-Up

Heating Systems & Furnace Maintenance Services

Seasonal Furnace

When it gets cold, you want assurance that your furnace is running efficiently and that it will not break down at peak temperatures. Just like a car, your heating, ventilation, and air conditioning (HVAC) systems must be maintained and inspected to ensure safety, maximize both energy efficiency and your comfort, and ensure maximum system lifespan.

We recommend that homeowners be proactive and have an annual furnace tune-up.

Regular Furnace Tune-Ups:

  • Prolong the life of your system.
  • Save energy and money on utility bills by keeping your system operating at optimum performance.
  • Avoid breakdowns and the need for emergency service calls when the weather gets cold.
  • Keep your system’s warranty in good standing – most homeowners are unaware of their voided warranty if they do not service the system annually.
  • Our team of NATE certified technicians are exceptionally skilled and certified to work on all air conditioner brands.

Furnace Tune-Ups include;

  • Carbon Monoxide: We check for the presence of unsafe levels of CO2.
  • Combustion Chamber/Heat Exchanger: Our technician will look at the condition of both the combustion chamber and heat exchanger
  • Burner Flame: Check for proper features such as gas and air adjustment and clean the burner, as necessary.
  • Pilot/Igniter: Inspect operation and clean, if necessary.
  • Vent Pipe to Chimney: Check condition of pipe and draft force.
  • Motors: Check operation of motor and oil as needed and replace belts, if necessary.
  • Burner Compartment: Remove all dust and scale from the burner compartment and any other essential parts.
  • Blower Wheel: Check condition of the blower wheel and clean, as necessary.
  • Flame Sensor/Pilot Safety Timer: Check the condition of the flame sensor and pilot safety timer and replace thermocouple, as necessary.
  • Furnace Filters: Check the condition of furnace filters and indicate proper replacement size.
  • Controls: Check operational control sequence, including safety controls and thermostat.

Some Furnace
and A/C Problems Or Failures That Might Not Be Discovered Without An Annual Inspection:

Safety Issues

  • Carbon Monoxide (CO2) Poisoning from an improperly vented furnace. The vent can work safely for years, then suddenly not be venting safely due to something as simple as a bird’s nest built at the top of the vent.
  • Carbon Monoxide Poisoning from a cracked Furnace Heat-Exchanger. Your gas furnace burners heat a metal structure (heat exchanger) inside your furnace. The blower moves air over this structure and distributes the heated air to the home. Over the lifetime of the furnace, it’s not uncommon for a heat-exchanger to crack due to years of expansion during heating & contraction when burners are off. A cracked unit allows carbon monoxide into the home.
  • Because Carbon Monoxide build-up can occur at any time, and for a myriad of reasons, your safety is dependent on having working CO2 Detector. It is imperative to know CO2 detectors wear out after at ten years. They can appear to be working correctly and may work during a test, but the ability of the detector to do its job is unreliable at ten years.
  • Replace the battery annually (or when detector beeps) and replace the detector once it is ten years old. Put the install date on the ceiling side of Detector before installation.
  • The cooling-coil (inside the furnace & not visible) can clog with dust, even with proper filter changes (the filter does not catch everything). This coil is what removes humidity from the home, so it’s wet most of the time. Moisture and dust are all that mold needs to grow. Then mold-spores are blown through the house by the furnace.

Inconvenience Issues

  • No heat due to improper gas pressure in the gas furnace. The gas valve will not open due to improper gas pressure. If gas pressure is too high/low, the valve will not open (a safety feature).
  • No heat due to a failed furnace igniter. Igniters fail over time due to the rapid expansion and contraction of the metal (which heats to the point it produces an orange glow) which ignites the burners.
