5 Liabilities When You Skip Yearly HVAC Checkup

HVAC - 5 Liabilities When You Skip Yearly Checkup

Most of the time, the home furnace works silently yet efficiently on its own without needing your attention. Since your old yet trusted furnace continues to warm your homes during the cold season, Toronto homeowners can easily be tempted to skip the suggested yearly HVAC checkup. After all, filters are changed on a regular basis, and there are no unusual sounds coming from it to make you think otherwise.

But the thing is, skipping one yearly checkup becomes two, then three and so on. Because you no longer spare the attention it needs, your furnace will eventually break down from continued neglect and overuse. You might be lucky not having to buy a new one, but sometimes, repairs can be pretty expensive too. There are a lot of associated liabilities, when you forego the required yearly maintenance your unit requires and here’s why:

FAILURE TO CONTROL THE TEMPERATURE

The amount of heat delivered by the furnace is being curbed by the temperature control. Once there is no more control on the unit, it can no longer prevent itself from overheating and eventually get burned up. Most new furnaces are designed to have its indicators that will be triggered once it starts to malfunction, but other units might not have this feature in place. A worn out furnace, or a unit that has a failing temperature control, cannot detect any malfunctions will necessitate a repair to prevent any threats of danger from happening.

OBSTRUCTED EXHAUST

This scenario has two safety issue. First, the toxic gas cannot go out of your home if your exhaust is congested. And since it has nowhere else to go, it will gather around your home’s utility room and then disperse from there. Second, a furnace can recycle and depressurize better if its exhaust is not clogged. But when it is, a buildup grows inside that can potentially wreck the furnace. The irony in this issue is that clearing the exhaust is a pretty simple and easy task to carry out that was left unattended for so long.

FAILURE OF THE SAFETY PRESSURE CONTROL

The need to cycle air and force it out of your home puts a great deal of strain on any Forced Air System. There are many components in a furnace, and the presence of safety pressure controls limits the chance that a furnace will harm itself. Its safety switch automatically shuts off the entire system until it can be checked by a professional technician once the pressure exceeds what is normal. Once the safety control fails, the high pressure forces the furnace to become a ticking time bomb that can explode anytime once it is not serviced by a technician right away.

MALFUNCTION OF THE IGNITION

Electronic Ignition Systems are a part of modern furnaces instead of the conventional pilot light. This electronic ignition helps you save on energy since it does not have a pilot light that constantly lights up once the ignition starts malfunctioning. Over time, it can be exposed sensitive gas lines and ignite a deadly spark once the furnace is up and running. Ignition malfunction consumes a lot of energy and is also a safety hazard at home.

MALFUNCTION OF THE FLAME ROLL-OUT SAFETY

There is a delicate balance that must be maintained for gas furnaces to work properly, like having the correct amount of air and fuel, for instance. The components that balance the metal corrodes and also breaks down. Soot blockages inhibit excess gas from going out the exhaust as well. With the buildup of these gasses, there’s a high probability of a flame roll-out that can initiate a fire in your home’s utility room. When you unit is checked by a certified repairman, he can easily see signs of corrosion and inform you of this. So, you’ll be able to adapt measures that can prevent it from happening especially in the middle of winter.
