Radiant systems may use pipes or wires if electric. Much of the distribution system will not be visible during this 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. 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 evaluate the operation of electronic air cleaners but will comment on cleanliness if present. 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 .
