Lewisville Furnace Repair
Furnace Maintenance, Repair and Replacement by Frost Brothers Heating and Air 972-874-1001. Even in relatively mild winter climates like Lewisville, a properly functioning gas furnace provides warmth on those days when the outside ambient temperature falls below the comfort threshold.
Furnaces are a substantial investment and when they breakdown, the inconvenience and added expense is extremely frustrating. With rising fuel costs, it is important to properly service the heating and cooling system and recognize when it may be appropriate to consider replacing an aging gas furnace. The Frost Brothers Lewisville furnace repair team has something for you to think about: You will save more money on utility bills by upgrading your furnace and your air conditioner or heat pump.
How a Lewisville Furnace Works
When the thermostat calls for heating, a relay is activated that engages an inducer fan. As soon as the air flow is sufficient for combustion, a valve opens that accommodates a specific amount of gas that is ignited by either a hot surface or spark ignition system.
After the gas begins burning, the igniter will shut off. For a set period of time, usually around two minutes, the gas heats up a stainless steel gas to air heat exchanger. When the heat exchanger reaches a predetermined temperature, a blower begins forcing air across the heated surface. This action warms the air which then distributed through the duct system into the living area.
Understanding AFUE Ratings
The Annual Fuel Utilization Efficiency (AFUE) is an industry standard measurement for comparing different brands and models of furnaces. A higher AFUE number indicates a more efficient furnace. An 80% AFUE rated furnace delivers 80% of the generated heat directly into the building while 20% is vented outside.
Should You Repair or Replace an Old Furnace
Lewisville Furnace Installation
Older Lewisville furnaces are costly to repair, expensive to operate and raise safety issues. Many furnaces purchased in the early 1990’s have an AFUE rating of 65 or less and are extremely inefficient and expensive to run. Purchasing a new 90 AFUE rated furnace can save up to 30% on annual heating bills.
A cracked heat exchanger can allow poisonous carbon monoxide to leak from a furnace. Any evidence such as changing flame colors or flames “leaning” to the back of the furnace should result in an immediate call to a professional HVAC contractor like Frost Brothers.
Furnace Filter
Furnace filters serve as a barrier to prevent harmful particulate matter from entering the duct work and reducing the efficiency of the equipment. Filters are available in a variety of materials and configurations. Basic fiberglass filters are inexpensive and are used in the majority of Lewisville furnaces, but only filter out the largest contaminants. Pleated filters offer a larger surface area, while electrostatic filters, electronic air cleaners and HEPA filters all remove microscopic particulate matter.
