Dealing with repair issues is something a homeowner needs to get familiar with. All of the vital systems under your roof will break down at one time or another. When your HVAC system fails, you will need to figure out whether unit repair or replacement is the best solution to your problem.
If your existing HVAC unit is over ten years old and unreliable, replacing it is a good idea. Most homeowners fail to realize just how many HVAC unit replacement options are on the modern market.
Attempting to select a replacement HVAC unit without the help of professionals is a recipe for disaster. If the wrong size unit is chosen, you might face some of the problems covered below.
Improperly Sized HVAC Units Use Lots of Energy
Perhaps the most common problem that you will face when having an improperly sized HVAC unit installed is high energy bills. If the unit in your home is too small, it will have to run continuously to maintain a comfortable temperature. The longer your unit runs before cutting off, the higher your energy consumption rates will become.
Consistently overworking a unit that is too small for your home can also lead to overheating. Once your unit starts to overheat, it is only a matter of time before it shuts completely down. You can avoid these problems by allowing HVAC professionals to select your replacement unit.
Issues Involving Short Cycling
Investing in an HVAC unit that is too big for your home can also be problematic. A system that is too big for your home will have problems with short cycling. This problem occurs when an HVAC unit cools too fast and is unable to complete a running cycle. Units that constantly short cycle experience an increased amount of wear and tear.
This means that your improperly sized unit will be overrun with repair issues from day one. An HVAC professional will consider a variety of factors like your home’s square footage before suggesting HVAC unit replacement options.
You Need a Cooling Load Calculation from a Pro
As you can see, having a unit that is too big or small for your home can be extremely problematic. If you want to avoid the issues covered above, allowing professionals to perform a cooling load calculation before a new HVAC unit is chosen is important. During this load calculation process, HVAC professionals will consider factors like:
- How many people live in the home
- Number of windows
- Number of rooms
- Room volume
- The insulation in your home
- The amount of heat given off by appliances and lights
Once an HVAC professional has this data, they can accurately assess the tonnage needed to heat your home. After the right unit is selected, HVAC professionals will begin the process of getting it installed. With their assistance, you can get your new HVAC unit in place and working in no time.
