Heating/Cooling 

28
- Description


Our description of the heating system includes where the unit is located and the fuel used to generate the heat. Forced air furnaces and water boilers can operate on gas, oil or electricity. Heat pumps utilize electricity to drive the motors and compressors. Furnace size is listed for reference only, if available, and no calculations are performed during this inspection to determine the adequacy or efficiency of the heating system.

29
-Condition


Systems are tested using normal homeowner operating controls. If pilots or circuit breakers are off at the time of the inspection, the inspector will not ignite or activate the system. You can contact the utility provider for evaluation of the heating system.

30
-Venting


Fuel burning appliances exhaust the products of combustion to the exterior through vent pipes. Vent pipes utilize caps to prevent moisture entry and to stop backdrafting. Backdrafting means that the products of combustion are escaping into the home instead of venting to the exterior.

31
- Combustion Air


When fires burn, they consume oxygen. Fuel that burns completely is harmless and creates only carbon dioxide. Fuel burning appliances must be provided with a constant source of fresh air for the fuels to burn properly. If air is not provided to the fire, incomplete combustion may occur which could produce carbon monoxide. Be sure not to block any air vents around or near your heating systems. Also be advised that maintaining clean air filters is important not only to the air you breathe, but to the operation of the unit as well.

32
- Burners


It is impossible to see an entire heat exchanger inside most furnaces, so the inspection does not comment on this component. If there is an uneven or unusual flame pattern or there is rust, charring or deterioration in the burner chamber, we recommend a further investigation of the unit.

33
- Distribution


Most heaters utilize some method of moving the furnace generated heat to the rooms which need the heat. Forced air heaters use ducts and registers. Water heating systems use pipes and radiators or convectors. Radiant systems may use pipes or wires if electric. Much of the distribution system will not be visible during the inspection and cannot be judged. For instance, water piping that is buried below or in the concrete floor slab may have leaks that are not detectable without specialized equipment.

- Normal Controls


Normal operating controls are homeowner operated devices such as a thermostat, wall switch or safety switch.  Loose thermostats should be secured and thermostats that are not centrally located or on outside walls should be relocated for better furnace performance.

35
- Air Filters


Regular cleaning or changing of air filters is important for proper furnace performance.  Dirty filters can cause damage to the heater and waste energy dollars.  We do not evaluaet the operation of electronic air cleaners but will comment on cleanliness if present.

36
- Heating Notes


Our evaluation of the heating system is visual only and does not include dismantling the unit.  A service technician should be consulted for an in-depth evaluation, cleaning and adjustment of the furnace for optimum performance and safety.  Most local gas companies will perform a safety check and light gas pilots for their customers prior to the heating season.  We also do not evaluate humidifiers built onto the heating unit.

37
- Evaporative Cooler


Evaporative coolers (commonly called swamp coolers) utilize air flowing across moving water to humidify and cool the house air.  Standing water that is left in the unit for extended periods of time can breed bacteria.  Evaporative coolers should be drained at the end of each cooling season and cleaned prior to use.

38
- Air Conditioner


Air conditioning systems rely on a constant flow of air through the system to properly operate.  Restricted air flow from dirty filters or blocked coils can cause icing on the evaporative coil.  This may make the air from the unit appear to be colder but is actually harmful for the system.Air conditioning systems rely on a constant flow of air through the system to properly operate.  Restricted air flow from dirty filters or blocked coils can cause icing on the evaporative coil.  This may make the air from the unit appear to be colder but is actually harmful for the system.
