10 Things To Expect During Your Next Gas Heat Maintenance Visit


What happens in an HVAC maintenance visit, anyway? We're here to decode the mystery for you. Here are a few things to expect at every visit:

1. It could take up to an hour and fifteen minutes to service.
Yes, you read that right. It could take over an hour to properly inspect a gas furnace. An HVAC professional wants to help you. An inefficient heater could cost you hundreds of dollars in energy bills. Heaters have many parts that keep it running smoothly, so it can take time to properly inspect all of them.

2. Your burners will be cleaned.
This is not only essential to your energy efficiency, but your health. Dirty and inefficient furnaces can produce large amounts of carbon monoxide, which is toxic to humans. The older the furnace, the more often it needs to be inspected.

3. The flue will be inspected.
A flue is the pipe where the gas exhaust is emitted from the gas furnace. If the flue becomes blocked or has leaks, carbon monoxide could escape into your business or home and this is extremely dangerous. A blocked flue can also cause the furnace to shut off and not operate at all.

4. Heat exchangers will also be inspected.
Heat exchanger problems can also lead to toxic gases in your home. It is absolutely necessary to get these things checked, especially with an older furnace.

5. Gas pressure will be checked and reset if necessary.
In the gas pressure is set too high, the furnace will run too hot and can cause premature burner and heat exchanger failure. If the gas pressure is set too low, the burners will not light properly and the furnace will not heat to capacity. The gas pressures are completely different for LP and natural and should always be checked by a professional.

6. Electrical work will be checked for any possible problems.
This may seem fairly obvious, but faulty electrical work can lead to furnace problems and safety hazards. Electrical wires are tricky and should always be checked by a professional.

7. Fan motors may be oiled.
After some time, fan motors can slow down or seize due to lack of oil. By adding oil, it will help to make sure that the fan is working in the most efficient way possible. This is especially true for the older motors. Most motors today are sealed and permanently lubricated and no oiling is needed.

8. All safety devices will need to be checked.
There are devices in furnaces, especially newer ones, that are designed to ensure the safety of a home or building. These devices usually turn a furnace off before they get too hot. If these devices are faulty, it could be a hazard.

9. The ignition will be checked.
Gas furnaces use an igniter to electronically light the gas and heat in a building. Igniters prevent a homeowner from lighting a furnace manually, so a properly working igniter is essential for a heated home.

10. Air filters will need to be inspected.
Furnace air filters do exactly what one would think – they keep the air flowing through your home clean. A clean filter is necessary for an efficiently heated home and for capturing dust and allergens.
