Why Proper Sizing of Heat Pumps Matters
If your heat pump is improperly sized, you'll experience the following issues:
- Comfort. Undersized units may not deliver enough heating or cooling, leaving you cold during the winter and warm during the summer. Oversized units, meanwhile, tend to heat or cool spaces too quickly. This makes it difficult to maintain consistent temperatures.
- Energy efficiency. An undersized heat pump will struggle to meet your home's heating and cooling demands, causing it to run continuously and use energy. Conversely, an oversized unit will heat or cool too quickly. This leads to short cycling, in which the unit turns off and on frequently. Over time, short cycling can waste energy and increase your bills.
- System longevity. Improper sizing causes heat pumps to wear out faster. Undersized systems often experience strain from constant operation, while oversized units may break down due to short cycling.
Another important factor is climate. While Portland has a relatively mild climate, temperatures tend to fluctuate between seasons. Proper sizing helps ensure your heat pump is equipped to manage warmer summers and colder winters.
How to Calculate the Right Size Heat Pump for Your Home
You can estimate the right heat pump size by calculating the required BTUs (British Thermal Units) per square foot. In general, homes need about 16 to 30 BTUs for every square foot. So, if your home is 1,500 square feet, you'll need a heat pump that produces between 30,000 and 45,000 BTUs.
Instead of doing the math yourself, you can use an online heat pump size calculator. Ideally, you should use one designed for the Pacific Northwest, which adjusts for the region's unique climate and temperature fluctuations.
Whether you use an online tool or make your own calculation, it's important to remember that these are just rough estimates. For the best results, you should contact an HVAC technician. In addition to home size and climate, technicians consider the following factors:
- Insulation
- Home layout
- Number of windows
- Ceiling height
- Condition of your ductwork
Through more comprehensive calculations, HVAC technicians can help find the most accurate size.
Common Mistakes When Sizing Heat Pumps
Although it may be tempting to determine heat pump size on your own, the task is easier said than done. Here are some mistakes that homeowners commonly make:
- Overestimating cooling needs. Portland experiences occasional heat waves, but summers are generally mild. Many homeowners mistakenly select an oversized heat pump based on rare heat extremes.
- Underestimating heating needs. Portland’s damp, cold winters are often harsher than they appear. Many homeowners select undersized units, assuming the winters will be milder than they are.
- Neglecting factors. Some homeowners fail to consider their home’s insulation quality, location, or window amount, all of which influence heat pump performance.
