We have done furnace services numerous times for last 10+ years. All that this technician did was to vacuum inside the furnace, asked me to turn on and turn off furnace, and said it is working fine. He didn't clean the burners, didn't check heating effectiveness, didn't check / change the filter ... Total rip off. I am calling amazon customer service.

Turn off the gas supply valve, typically located by your gas meter on the gas inlet pipe. Turn off the gas by rotating the valve one quarter turn with an adjustable wrench. When the gas is off,  the valve’s oblong stem points perpendicular to the inlet pipe. Then call your gas utility or the fire department from a remote location. Do not return to your home until you know it is safe.

An annual inspection of your unit can ensure that the various potential problems mentioned above are detected early, and before they require complete replacement. During this inspection, for instance, a professional might find small cracks in your heat exchanger or a faulty seal in your blower motor. Some manufacturer's warranties even require these annual inspections to maintain validity. Typically, your furnace inspection will cost between $80 and $150 depending on the area in which you live and the professional you work with.
Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.
This job involves removing the access panel, loosening a couple of bolts that hold the blower motor at the proper tension, and adjusting its distance or realigning the belt. In many cases, it’s a good idea to remove the belt and buy a replacement at a home center. Last, when reinstalling the belt, be careful not to over-tighten it; this can wear out the motor bearings.
Your furnace's flame sensor is essentially a safety mechanism. As a thin metallic rod in front of the flame inside the unit, it's sole purpose is to confirm that your gas valves only open when a flame actually exists to burn that gas. When the flame sensor stop working, on the other hand, gas leaks can occur. To repair your furnace's flame sensor, expect to spend between $80 and $250. Even a full replacement of this part typically does not go above that range.
If you have an older furnace with a standing pilot light, it’s possible that the pilot light has been extinguished. First, confirm that the light is out. Then, turn the gas valve to the off position and wait five minutes. If there is a reset button on your furnace, turn the valve to the pilot position and hold a flame to the dedicated pilot opening while pushing the button for about 30 seconds. (If the pilot doesn’t light on the first attempt, wait a few minutes and repeat the procedure, this time depressing the reset button for 45-60 seconds.) Once the pilot is lit, turn the gas valve back to the on position. If the pilot light won’t stay lit, it’s possible that there is an issue with the thermocouple or ignition system. Call an HVAC professional for assistance.

While there's nothing you can do to guarantee your air conditioner or furnace will never need repairs, there are ways to take better care of your system. Changing out the air filters every 3-6 months, making sure nothing is obstructing or interfering with the outside unit, and keeping all vents unblocked in well-used rooms will help keep your air conditioning and heating system operating efficiently.
