Gas Furnace Maintenance FAQ

Question 1. What are the benefits of having furnace maintenance?
The answer to this question is simple. There are many benefits. However, there are three major benefits to this service. One is to insure that your furnace and its systems are protected. When a furnace is ignored, over time problems will begin to occur. When systems begin to wear out and don’t get replaced or repaired, total furnace failure can happen. To prevent failure of the furnace, have your unit inspected, serviced, and if need be, replace the broken or worn down component. The second benefit, which goes with the first, is that when your furnace is serviced it will insure reliability. When a furnace is serviced and maintained, your home will be warm all winter long and it won’t break down in the middle of winter. The third benefit is better efficiency. When a furnace is serviced it is operating as smoothly as possible. With all filters cleaned along with the internal systems lubed and cleaned, your furnace will run with maximum efficiency which help reduce the cost of heating your home.

• The blower’s door seal is tested and the blower wheel is also cleaned. The blower motor amp-draw is also tested to ensure proper performance.
