Repair or replace existing ductwork
Aging ductwork needs attention just the same as any other home system does. If they are poorly maintained and rarely cleaned, ducts can become inefficient, preventing hot or cold air from circulating in the home and decreasing energy efficiency by as much as 40 percent. Older systems are also subject to the stresses of age, including leakage and cracks, which may require complete replacement of certain areas or components of a duct and vent system.
Reasons to replace
In situations wherein basic sealing and patching jobs are not enough to improve the efficiency of your heating and cooling system, or if problem areas are difficult to access or too numerous, completely replacing your ductwork may be in order. This is especially the case in older homes where time has caused too much damage to easily fix the system or where materials are of sub-par quality. This type of job is as complex and difficult to price as original duct and vent installation because factors such as home size, number of vents, temperature zones, and accessibility all affect the time and effort required to complete this type of project.
Maintenance: how to keep ducts & vents clean
Installing ducts and vents in a new or existing home sets homeowners up for an easy solution to meeting their heating and cooling needs. However, like any home system, they occasionally need maintenance in the form of cleaning. Newer systems that use air filters may not have a need for regular, professional duct cleaning. But for older systems or systems that appear to be producing dust or running inefficiently, a professional cleaning is a good way to ensure optimal performance standards.
Professional cleaning involves an hvac professional servicing every element of your system’s heating and cooling elements, such as supply and return air ducts, diffusers, grilles, exchangers, coils, fans, drip pans, and the air distributing unit. This clears out dust, mold, and pollen.
In addition, homeowners can keep their systems clean themselves through good habits such as regular filter changes. It is also possible to reduce the need for regular cleanings by having hvac professionals apply a sealant in the ducts, which prevents dirt and dust from circulating in the air. They may also apply a sanitizer when cleaning, which reduces the growth of mold and kills pollen and other allergens in the system.
