Frequently Asked Questions

Frequently Asked Questions

1. How long should a Gas Furnace last?

The standard life expectancy of a gas furnace is somewhere between 20-25 years depending on the quality of the unit and the location. Units installed in crawlspace or a damp basement generally don’t last quite as long.

2. Is it safe to have a Gas Furnace in my house?

Modern gas furnaces are very safe and quiet. The advanced controls and safety functions make them as safe, if not safer, than other heating options for your home.

3. I don’t have natural gas at my home. Can I still have a Gas Furnace?

All of our furnace models can be converted for use with bottled gas.

4. Will a Gas Furnace cause me to have dry air in the winter time?

Dry winter air is a concern with any type of heating system. In the process of heating air you automatically remove moisture. A gas furnace typically heats faster than other heating options and can cause the air to lose moisture quicker. This problem can be resolved by adding a humidifier which automatically adds moisture to the air as needed.

5. What is the difference between a Gas Furnace and a Heat Pump?

A heat pump is a type of heating system that absorbs heat from the outside air and transfers it to your home. A gas furnace relies on combustion to produce heat. A heat pump works off of electricity alone, while a gas furnace requires both electricity and gas. The downfall of a heat pump is that it loses its ability to provide sufficient heat as the outdoor temperature drops and requires a backup heating source. The benefit of a heat pump is that it also acts as an air conditioner in the summer.

6. Will a Gas Furnace work if I lose electricity?

No. Even though a gas furnace uses gas combustion to produce heat, it must have electricity to function.

7. Which manufacturer makes the best furnace?

The two brands that we represent are York and Trane. We feel that these manufacturers have a high commitment to quality. But that’s not to say that there are not other good brands out there. We believe the most important part of choosing a heating or cooling system is choosing a quality company to put it in. A gas furnace that is installed properly and with care will last much longer, and give much better performance.

8. What does AFUE mean?

Every new gas furnace must be tested by an independent laboratory to determine its efficiency rating (AFUE). AFUE stands for Annual Fuel Utilization Efficiency. The higher the AFUE rating, the less gas a furnace will require to produce its rated heating output.

Our focus and specialty is quality installation, service and repair of heating and air conditioning systems - both residential and commercial.
