4 Problems Caused by Oversized HVAC Systems

At Rooter Hero Plumbing & Air, we provide comprehensive HVAC services for our local clients including air conditioning repair and replacement. When it comes to heating and cooling systems, a common misconception exists that 'bigger is always better'. However, an oversized system can lead to a lot of problems that not only impact your comfort but can also increase costs and decrease the lifespan of the system.

Unstable Operation

Short cycling occurs when your HVAC system frequently turns on and off, never reaching optimal operation before shutting down. The reason behind this is simple. An oversized system will reach the set temperature too quickly, causing it to shut down prematurely, only to restart a short while later when the temperature changes. The consequence of short cycling is a significant strain on your system. Continual stopping and starting can cause wear and tear on the HVAC components, reducing the overall lifespan of the system. In addition, the constant fluctuation of temperature can lead to an unstable indoor climate, making your living spaces less comfortable.

Inconsistent Temperatures

You might think that an oversized HVAC system would ensure your home stays extra warm in winter and super cool in summer. Ironically, the reality can be quite the opposite. An oversized system can make your home too hot or too cold, creating an uncomfortable living environment. The reason is that an oversized HVAC system can heat or cool your home too quickly, creating significant temperature swings and hot or cold spots. This rapid heating or cooling doesn't allow for the adequate distribution of conditioned air throughout your home, leading to uneven temperatures.

Increased Indoor Humidity Levels

Humidity control is one of the essential functions of an HVAC system. However, an oversized HVAC system can struggle to maintain appropriate humidity levels inside your home. This is because while cooling your home, an HVAC system also removes moisture from the air. An oversized system cools the air too quickly, not leaving enough time to effectively dehumidify. The result is a damp, humid indoor environment that not only feels uncomfortable but can also promote the growth of mold and mildew. These can cause potential health issues, especially for individuals with respiratory conditions or allergies.

Skyrocketing Costs

An oversized HVAC system comes with increased costs. First of all, the initial purchase price of a larger system will be higher. But the costs don't stop there. An oversized system uses more energy than required, leading to higher utility bills. The frequent on-and-off cycles can also lead to repeated heating and AC repair services and a shortened lifespan, adding to the overall costs. In contrast, a correctly sized HVAC system can operate more efficiently, save energy, and reduce long-term maintenance costs.
