HVAC Terms: What Does It Mean?

We get it. HVAC comes with a lot of new terms. We can help you sort through it all and figure out the things that matter to you.

What's an Inverter?

A Daikin inverter system means that the compressor (the heart of any system) adjusts its speed depending on the heating or cooling demand. For example, on a mild, temperate day, your system doesn’t need to run at full speed, but rather ramp up or down depending on the outside temperature and your indoor settings.

Inverter technology helps prevent the common, and uncomfortable, temperature swings normally experienced with non-inverter (single speed or dual speed) traditional HVAC systems. An inverter system can reach your comfort setting faster, and keep it steady, creating maximum comfort that doesn’t fluctuate. Inverters are also very efficient and may result in more consistent humidity throughout your home.

What is a Heat Pump?

Well, first of all, it’s a confusing name. Despite being called a “heat” pump, it can actually be used for both heating and cooling. Heat pumps are an efficient way to achieve comfort in your home, by moving heat where it needs to be to make you comfortable. In the winter, that means moving heat from the outside indoors, and in the summer, it means moving heat from inside your home, outside where it belongs. Heat pumps work using electricity, not by burning gas.

All Daikin ductless systems heat using heat pump technology, while central air systems are available in both heat pump or gas furnace. Daikin Fit systems allow for dual fuel capability, switching from heat pump to gas furnace heating only when necessary.

What is SEER? (Seasonal Energy Efficiency Ration)?

SEER stands for Seasonal Energy Efficiency Ratio. It is a measure of your cooling system’s energy efficiency, The higher the number, the better. The SEER value usually ranges between 14 and 25. Note, achieving a higher efficiency system is only possible if the system is designed and installed properly. We recommend consulting a Daikin Pro to discuss the best options for you and your budget.

What is HSPF?

HSPF stands for Heating Seasonal Performance Ratio. Similar to the SEER value for cooling mode, the HSPF value is a measure of the heating efficiency of your Heat Pump system. Again, the higher the number, the better. While the HSPF value is an indication of efficiency, you should also consider the heat pump system’s heating capability when outside temperatures are low. At Daikin, we have ductless heat pump systems that can reliably provide heating down to -13F. Ask your Daikin Pro about Daikin Aurora systems.

The Benefits of Ductless/Mini-Split

A ductless system is exactly what it sounds like. It’s the perfect system for heating or cooling areas where there are no previously existing ducts. They might be used as solutions for a whole house, especially older houses where ductwork would be impossible, or in new additions where you need a solution for a single room. The major advantage of a ductless system is that you can control up to eight zones with a single outdoor unit, and enjoy the right temperature in every room.


The Benefits of Central Air

Central Air offers comfort over large living spaces. They are built to help whole homes achieve total comfort. They use existing ducts, or new ducts can be constructed if the floor plan allows. Central air systems also have a greater ability to integrate with air quality products, and can allow you to add filtration, indoor purification and humidity controls. Ask your Daikin Pro about the Daikin One Ecosystem.

Frequently Asked Questions

Now that you know the terms, here are a few more questions that often come up. And remember, A Daikin Pro can answer many, many more.

Q: Are heat pumps a new technology?

A: No. Heat pumps have been around for decades. The technology has advanced significantly in the last 10 years, especially for cold climates. They are the most popular HVAC choice in Europe, Japan, and Australia among other major regions, and they're installed in more than 12 million US homes, with Daikin being a renowned worldwide leader in this technology.

Q: Do I need ducts for a heat pump system?

A: Heat Pump systems are flexible—you can install a heat pump system with or without existing ductwork. Your Daikin Pro can help you assess what is best for your home. If you already have ductwork, it’s easy to integrate a heat pump into your existing infrastructure with Daikin Fit. And if you don’t have ductwork in your home, you’ll install a ductless mini-split system. Mini-splits are small wall-mounted, floor mounted, or wall-recessed units that send conditioned air directly into your home.
