CHOOSE YOUR HVAC UNITY WISELY!

Your HVAC system is essential to keep your home comfortable, but it is also one of the most expensive, energy utilizing appliances in your home. To lower the strain on both your wallet and the environment, it is important to consider efficiency when shopping for a new HVAC system.

How to Choose the Most Energy-Efficient HVAC System

To choose the most energy efficient HVAC system for your home, you have to first understand your options. For heating your home, the most energy efficient HVAC systems currently available are heat pumps (both geothermal and air source) and furnaces. 

Heat pumps are also a very efficient way to cool your home. For the summer, your most efficient cooling system will be either a heat pump or an air conditioner. 

The specific HVAC system you need will vary widely depending on both your climate and the age and layout of your home. The best way to choose the most efficient system for your home is to consult an HVAC technician. Call AirPlus today to find the system that will work most efficiently for you.

Differences Between Energy Efficient HVAC Systems

Not only will different HVAC systems be more efficient for different homes—they also each have a different rating system for efficiency. 

Air-Source Heat Pumps 

Heat pumps move air in and out of the home to both heat and cool it. In heating mode, they use refrigerant to cool air and move heat in from outside. Heat pumps are one of the most energy efficient heating systems around, but do not work as well in colder climates.

Best Heat Pumps for 2021

The efficiency for heat pumps in heating mode is measured in HSPF, which represents total heat output. SEER rating is used to measure the efficiency of heat pumps in cooling mode.

Geothermal Heat Pumps

Geothermal heat pumps use the earth as a source of heat. While they are much more efficient and stable than air-source heat pumps, the high cost of installation means that they are not most homeowners' first choice of HVAC system.

Furnaces

Furnaces are the most common heating system used in residential homes. Furnaces can run on gas, oil, or electricity and vary widely in their efficiency, with older units being much less efficient than newer ones. 

Furnace efficiency is rated by AFUE (Annual Fuel Utilization Efficiency), which is a measure of the percentage of energy use that actually goes into heating the home. For example, a furnace with an AFUE of 95% means that 95% of the energy you are paying for is actually being used to heat your home.

Air Conditioners 

While a heat pump can heat and cool, an air conditioner is used only for cooling your home. Because of this, air conditioners are typically paired with a furnace to provide heat during the cold months. SEER, or Seasonal Energy Efficiency Ratio, is used to measure air conditioner efficiency.

What kind of HVAC system is most efficient?

While there are several types of HVAC systems, it is likely that your home either uses an air conditioner and furnace or a heat pump as its HVAC system.

For cooling your home, the most energy efficient HVAC system is a heat pump or an air conditioner.

What does SEER mean for my home’s cooling system?

Your AC or heat pump SEER rating, or Seasonal Energy Efficiency Ratio, is a measurement of its efficiency. Generally, the higher the SEER rating, the more efficient your appliance is, though there are other factors that affect efficiency. 

Currently, the lowest SEER a new appliance can have is 14, so you shouldn’t find anything lower than that if you are buying a new system. A good SEER rating to shoot for if you want a highly efficient system is 20.

Other Factors That Affect Your AC’s Efficiency

While SEER rating will help you choose an efficient cooling system for your home, there are other factors that affect the efficiency of your HVAC system.

Modulating Units

A modulating or variable speed HVAC system is able to work at different speeds. For example, if you have your AC set at 70 degrees and it turns to 71, instead of turning itself on full-blast, a modulating system is able to cool your air more slowly, which improves its efficiency beyond the SEER rating. Variable speed systems will turn on less, which will save energy. Plus, they’re quieter and spend more time pulling humidity from your air since they work more slowly.

Installation and Ductwork

Even the most efficient HVAC system will not work up to its SEER rating if it is installed poorly or your ductwork is too small or designed badly. To have your new HVAC system installed professionally and in the most efficient way possible, call AirPlus.
