Gas Furnace Service Reminder


1. A poorly running gas furnace can release carbon monoxide in to your home.
2. Over 110,000 people die annually from carbon monoxide poisoning. That’s over 300 PER DAY!
3. Carbon Monoxide is colorless, odorless and tasteless making it undetectable by human senses.

How much does it cost?
A typical service fee for a propane or natural gas furnace is around $250.00. That’s it! You can often get a discount when you set up a multi-year service contract. Either way, it is a very small investment for the benefit of knowing that everyone is safe inside your home.

How long does it take?
Once an appointment is scheduled, the service technician should need no more than a couple hours on site to do a routine service. If service is done annually it should take less than an hour. Please do yourself, your HVAC tech and your home inspector a favor and make sure any stored items have been moved so there is clear access to the furnace.

Does it need to be done by a professional?
Yes. Absolutely. Definitely! Gas is nothing to mess around with. Also, the pros have the experience and specialized equipment to look deep inside the furnace. A cracked heat ex-changer is one of the primary causes of carbon monoxide being released in to the home. This could never be noticed by a home owner.

What are the common signs of a poorly running furnace?

1. Mineral deposits. These look like scattered baking powder and are the result of an improper air/fuel balance. When your propane/natural gas does not burn efficiently it creates condensation which dries in the exhaust vent and falls back in to the furnace in the form of mineral deposits. That might be more than you needed to know but it’s important for you to be able to identify potential issues.

2. Rust. As mentioned above, a poorly maintained gas furnace produces condensation. This moisture interacts with the metal parts of the furnace and causes rust to form. Rust is an organic substance that will continue to grow if left untreated. You will typically see rust forming on the gas vent pipe on your roof as well as the interior vent ducts above and inside the furnace enclosure.

3. Increased utility costs. It takes more gas to produce less heat when your furnace is not properly maintained. This cost can go undetected on a monthly basis but can represent hundreds of dollars in unnecessary gas expense.

4. Gas odor. There is a scent that is added to propane and natural gas specifically to help us detect even small amounts of it. The smell is for our safety. This goes without saying but if you ever smell gas, remove yourself and others from the area immediately and call the professionals. This can include calling 911, fire, police or even the utility company.
