One of the most common mistakes homeowners tend to make when purchasing an HVAC system is going with one that’s too big for their needs. If you weren’t getting good enough results from your old unit, it’s going to be tempting to go with a bigger, more powerful piece of equipment thinking it will give you the heating or cooling you are looking for.
However, as your HVAC contractor in St. George, UT will likely tell you, this isn’t actually the case. Bigger is not necessarily going to be better for your HVAC system—one that’s too big will be too inefficient and lead to a variety of problems.
Here are just a few of the reasons why you should be careful not to go too large with your HVAC system:
- Breakdowns: You’re more likely to encounter more frequent breakdowns with an oversized HVAC system. The unit will cycle on and off frequently, an issue called short cycling that indicates the system is working harder, burning more fuel and yet not delivering the conditions you want. The more this happens, the more you’ll experience part failure and expensive repairs. This problem can be avoided simply by having a reasonably sized HVAC system for your home.
- Earlier need for replacement: Having a system that’s too large and breaks down frequently will also likely result in an earlier need for a total replacement of the system. You should be able to get at least 15 to 20 years out of the average HVAC system, but if your system is too big, you might get only 10 years or less. This means you’ll have to spent a bunch of money to replace it a lot sooner than you otherwise would if you had gotten the correct size for your home.
- Lack of temperature consistency: Short cycling processes result in inconsistent heating and cooling in your home. This means you’re more likely to experience issues with hot and cold zones and uncomfortable conditions.
- Increased energy bills: An improperly sized HVAC system will be extremely inefficient and waste a lot of energy. It’ll start up more frequently throughout the day, and startup is when it’s most likely to use the most energy. This means you’ll see significant jumps in your energy usage that will cause increased energy bills.
- Poor air quality: An oversized HVAC system will not run long enough to get the moisture out of the air in your home, creating a humid environment that could result in the spread of mold, mildew or bacteria, all of which could reduce the air quality in your home and contribute to the spread of viruses.
- Excessive noise: Overly large HVAC systems will frequently cycle on and off and make a lot of noise, which could be a nuisance to you while you’re at home.
These are just a few examples of some of the reasons why it’s in your best interest to work with an HVAC contractor in St. George, UT to get a system that’s properly sized for your home. Contact Calaway Heating & Air Conditioning today with any questions you have about our services!
