Question: I know you inspect the heater, but do you also inspect thermostats?
Answer: Thermostats monitor the temperature of the living or working areas of your property, controlling when the heating or heating and cooling systems turn on and off. Proper operation keeps indoor temperatures comfortable and can save on utility costs. Thermostats are inspected as part of the overall mechanical system.
Some considerations when inspecting the thermostat include:
- Location
- Level
- Attachment
- Cleanliness and
- General condition
Because thermostats are meant to sense temperature in the rooms where we live, location is important. They should be on an interior wall near the center of the home, away from direct sunlight or radiated heat from fireplaces, radiators or other heat sources. They should be away from doors and windows that open and close frequently. Thermostats are generally located about five feet above the floor so they can be read easily. Thermostats may be controlled by a gauge, a dial or digitally with a panel of buttons. Digital thermostats can be programmed for specific temperatures based on day of the week and time.
Most thermostats for gas-fired appliances also have a variable anticipator to help prevent overheating. The anticipator "fools" the heating unit into shutting down just before the room hits the set temperature so that the heat remaining in the furnace finishes the job. Whenever changing a thermostat or having routine maintenance, it's a good idea to make sure settings for the anticipator are correct.
