Air Handler Versus Furnace
An air handler, also known as an air handling unit, is a device used in HVAC systems to regulate and circulate air. It contains components such as a blower, furnace or A/C elements, filters, and dampers. An air handler works alongside an air conditioner to distribute cool air throughout a home.
Differences In Operation
An important distinction between an air handler and a furnace lies in their operations. A furnace is primarily responsible for generating heat, using fuel like gas or oil, and distributing warm air throughout the house via ductwork. On the other hand, an air handler works in conjunction with an air conditioner or heat pump to circulate and regulate conditioned air.
While a furnace is a standalone heating unit, an air handler is more versatile. It acts as the central component of a heating, ventilating, and air-conditioning (HVAC) system, ensuring the circulation of both warm and cool air throughout the house.
Suitability For Different Climates
The suitability of an air handler or a furnace depends on the climate in which you reside. Furnaces are commonly found in regions with cold winters, where heating is a primary concern. They efficiently generate and distribute warm air, making them an ideal choice for colder climates.
On the other hand, an air handler is well-suited for areas with both hot summers and mild winters or for individuals living in temperate climates. Since air handlers can work with both heating and cooling systems, they provide year-round comfort by distributing both warm and cool air. Additionally, air handlers often feature enhanced air filtration capabilities, which can be beneficial for those with respiratory sensitivities or allergies.
Lifespan And Maintenance
When it comes to the lifespan and maintenance of an air handler, it’s important to understand the expected durability and the steps you can take to ensure optimal performance. Air handlers play a crucial role in heating, ventilation, and air conditioning (HVAC) systems, regulating and circulating air to keep your indoor environment comfortable. Let’s take a closer look at the expected durability of air handlers and some maintenance tips to extend their lifespan.
Expected Durability Of Air Handlers
An air handler is a durable device designed to withstand regular use. Typically, the average lifespan of an air handler ranges from 15 to 20 years. However, several factors can influence the actual longevity of the unit.
The quality of the air handler itself is a significant factor in determining its lifespan. Investing in a high-quality air handler from reputable brands such as Carrier, American Standard, Goodman, Trane, or Lennox can ensure greater durability. These brands are known for their reliability and produce air handlers built to withstand the test of time.
Additionally, regular maintenance and preventative measures can significantly extend the lifespan of your air handler. Following proper maintenance guidelines and promptly addressing any issues that arise can help prevent premature wear and tear.
Maintenance Tips For Optimum Performance
Maintaining your air handler is essential for ensuring its optimum performance. Here are some maintenance tips to keep in mind:
