Air Purifiers Versus Dehumidifier in Urbana, IL

Your home comfort systems work hard to provide you with year-round comfort. Your heating unit, your AC, and perhaps even your air purifier or humidification units do some heavy lifting. No matter how well these systems perform, your home’s ductwork ties everything together. If your ductwork in Urbana, IL has issues, you must seek to correct them right away. Shoddy ductwork causes your HVAC units to lose efficiency. It also makes them work harder, creating wear and tear and breakdowns.

At Dogtown Heating, Air & Plumbing, we see many instances of poorly maintained or incorrectly installed ductwork. We know how much these issues affect your overall efficiency. You may have paid a lot more for utilities for years and not even realized your ductwork is to blame. Understanding how ductwork directly affects home comfort empowers you to make positive changes.

The Impact of Inefficient Duct Design

The first thing you should realize about ductwork is that you must design it for the home. It’s not just a series of metal tubes workers slapped into place haphazardly. Proper ductwork requires precise measurements and a well-planned layout that fits your home’s floor plan. If you have issues like too many sharp turns, connections, or incorrect sizing, these problems restrict airflow. In some cases, issues have always restricted airflow. Homeowners just assume this is how their HVAC units operate. They are shocked to learn that proper ductwork creates a much different, more comfortable environment.

Inefficient design also causes hot and cold spots throughout the home. One bedroom is very comfortable, while another is too hot or too cold. Distances from the HVAC unit typically cause this. Poor ductwork does not allow the conditioned air to reach the room properly. These imbalances are rarely the fault of the HVAC unit itself. Rather, something with your ductwork keeps your temperature imbalanced.

Consequences of Leaks and Improper Sealing

Industry sources claim that many homes lose a significant portion of their conditioned air through leaks. You can lose up to 30% of your HVAC efficiency via poor ductwork. This doesn’t necessarily have to be a missing section or gaping hole either. Small leaks in seams cause this inefficiency. Ductwork should be airtight and is a critical part of your home’s thermal envelope. You throw money away if you have leaky ductwork.

Leaking and poorly sealed ducts create more problems than poor efficiency. They also cause your HVAC units to work much harder to condition the home. This premature wear and tear leads to costly repairs to your units. Leaks also create pressure imbalances. This results in a vacuum effect that pulls unfiltered air into your system and into your home. For instance, your system pulls dusty, dirty air from your attic and blows it directly into your home.

Why Ductwork Issues Should Not Be Ignored

If you suspect any ductwork issues, you must act by contacting a company like Dogtown Heating, Air & Plumbing. Even if the issue is minor, it can snowball into something major. Small leaks will not fix themselves. An undersized duct will not suddenly enlarge. Ignoring ductwork issues worsens the ducts while also keeping excess strain on your HVAC units. What could have been a simple ductwork tweak can turn into a failed duct system and broken HVAC units.

Increased energy bills are often the most noticeable consequence. In any economy, on any budget, no one wants to pay more for energy. It’s already quite expensive to run HVAC units for home comfort. Acting right away by giving us a call helps you avoid the long-term negative effects.

  • Excessive dust buildup on furniture shortly after cleaning
