Three Factors For HVAC Energy Efficiency
If you’re shopping for a new AC system in Texas, you’ll want the best one. Of course, you’ll also have a lot of options to sort through. But only the most energy-efficient systems with the cheapest electricity plans will get you the best savings. So, before you commit to an HVAC system, consider these three factors.
1. Navigating HVAC Efficiency Ratings
An AC system’s energy efficiency rating is a great way to calculate how much it will cost you to run it. But there are two different ratings that you need to know.
The Energy Efficiency Ratio (EER) measures the cooling output of a system divided by its overall power consumption. The cooling capacity of an AC is measured in BTUs (British Thermal Units). On the other hand, Seasonal Energy Efficiency Ratio (SEER) measures the same, but only during the cooling season (summer). The higher the SEER and EER ratings of an AC system are, the better.
Generally, window units only use EER, while central AC systems use both ratings. You may also see an Energy Star seal on a new AC. This means that the product went through rigorous independent testing, and it’s one of the most energy-efficient ones on the market.
2. Finding the Right Size AC System
A lot of factors determine what size HVAC system you need. The quality of your insulation, the amount of sun your house gets, and the number of people who live in your home, to name a few. But one of the biggest ones is how big your home actually is because that affects the size of your AC system.
If your AC is too small, it will need to run constantly to keep your home barely cool. However, an AC that’s too big for your home increases the chance of mold and uses more energy than necessary.
Generally, your AC unit should have a one-ton (12,000 BTU) cooling capacity for every 500 square feet of your home. So, if your home is 2,000 square feet, you need around a four-ton (48,000 BTU) AC unit.
The best way to find the right size AC system for your home is to hire a professional contractor. Make sure they use the Air Conditioning Contractors of America (ACCA) Manual J for their calculations.
3. What Type of AC System to Choose
Basically, there are three major HVAC types you can choose from when you’re shopping for a new cooling system:
- Traditional HVAC: These heating and cooling units can be either window or central types. They use electricity and will be one of the biggest expenses on your electric bill.
- Heat pump: While similar to traditional HVACs, the heat pump system works by moving heat from one area to another. In the summer, they remove the heat from your home and release it outside. Generally, heat pump systems use less electricity than air conditioners, making them more efficient.
- Geothermal heat pump: This system uses an underground pipe grid to control the temperature in your home. While it’s more expensive to install than other types of ACs, it’s also a lot more energy efficient and environmentally friendly. You may save more with a geothermal system long-term.
