A chilly home, strange odor or unusual noise when the furnace clicks on is a homeowner’s first warning to call a technician. Not every problem warrants a service call. Knowing when to call, and what information to can save time and money.
Before Placing the Call
Check the thermostat. Is the switch on? Is it set for the proper season and temperature?
Does your thermostat use batteries? Do they need replacing?
Your electrical system may have become overloaded. Check the master switch and circuit breaker or fuse to make sure the system has power.
Check the air filter. A plugged air filter limits air flow.
Find the furnace’s model and serial number. These are usually on the unit nameplate.
What To Tell the Dispatcher
Is the problem intermittent? Note if the problem occurs at certain times of day. Do any events coincide with the system problem? (Does a factory opening at 6:00 a.m. coincide with your furnace malfunctioning?)
Alert the dispatcher to unusual odors. Unfamiliar odors may signal abnormal operating conditions.
Tell the dispatcher if you want an estimate before any work is performed.
Provide contact information-- a cell phone or work number, or the name of the individual at home who can authorize the work.
Consider providing a "not to exceed" amount so the technician can perform services up to a stated dollar amount without signed authorization.
Request a NATE-certified technician--they know heating and cooling and have proven their knowledge.
Finally, minimize future service calls by having your home’s comfort system regularly serviced by a NATE-certified technician.
