Ready to replace your HVAC equipment but your head is spinning over which to choose? We’re here to simplify the installation process for you. Here you’ll get the quick-read definition and the pros and the cons so you’re armed with the knowledge to make the right decision for your household.

Terminology tip: the equipment below applies to your heating or cooling system.

Single Stage Equipment

Single stage equipment has been the industry standard since the beginning of heating and cooling, and it’s the most common. It turns on and off at 100% of its capabilities every time the thermostat calls for heating or cooling.

Pro: Single stage is the most economical choice when buying a new system.

Cons: It offers the lowest efficiency and lowest comfort levels. Plus, it can be a bit noisy.

Two Stage Equipment

Two stage equipment was introduced over 20 years ago and has proven to be a great upgrade when choosing to replace your HVAC equipment. It turns on low (at 70% of the unit’s capabilities) and operates this way for 10-15 minutes. Then the unit will turn on the high stage (at 100%) if the thermostat is still calling for heating or cooling.

Pros: Two stage equipment is efficient and produces less noise and more comfort as compared to single stage equipment.

Cons: It is more expensive than single stage and some service parts cost more when the unit requires service.

Buyer Beware: You may hear this type of equipment is variable speed. That is not true.

Communicating Equipment

Communicating equipment operates vastly different than the other categories and every brand on the market has major differences between them. The main takeaway is that this type of unit tries to match the current conditions that your house is dealing with. These units can adjust from 30-100% of their capabilities depending on what your house needs to provide the highest levels of comfort,efficiency and noise levels.

Pros: Communicating equipment is the most efficient of these three types of equipment. It also offers the lowest noise levels and highest comfort level in your home.

Cons: As you might guess, this is the most expensive option.

Terminology Tip: This is also called “Variable Speed” equipment.
