FAQs to INVERTERCOOL — InverterCool Skip to content



Q. What size universal system do I need?
A. The important factors to consider are:

The Size of the Area to Heat / Cool (Square Feet)

Your Local Climate (is it extremely hot or cold for extended periods of time?)

Insulation (an uninsulated area with drafts will have vastly different requirements than a well insulated area)

For a basic sizing, you can find Model Selection Tool. If you're still not sure what model to choose, you can try contacting our technical experts.

Q. Why would I want to purchase a residential heat pump system?

A. Heat pumps operate much like an air conditioner on electricity, but can be used to heat or cool your home. Best suited for moderate climates, InverterCool heat pumps can bring heating or cooling comfort for the entire home and can switch between the two quite easily depending on weather conditions. 

Q.What are the benefits of a programmable InverterCool thermostat?

A. A programmable InverterCool thermostat may help you save on your monthly energy costs. By customizing your home's heating and cooling system settings along with your schedule. You can make sure that you are not overheating or overcooling a vacant home. A customized thermostat schedule can in turn yield some extra monthly energy savings.

Q. Which is better and offers more energy savings, a heat pump or an air conditioner?

A. Both the heat pump and air conditioner are designed to use the refrigeration cycle to cool your home. To determine if one provides better cooling performance over another, you have to be sure you compare identically sized equipment with the same cooling features and efficiency ratings. But if your home needs an electric heat source, a heat pump can keep you warm too. Your air conditioner is designed just to keep your home cool.

Q. What is the difference between variable speed and a two-stage?

A. Variable-speed systems operate in longer, lower speed cycles throughout the day. A two-stage system ramps up, as temperatures become extreme, until it reaches the desired temperature inside then it drops to a lower operation to keep temperatures consistent. Both operation systems are more efficient than single-stage, on/off systems.

Q. What is a Heat Pump and what differences are there when comparing it with a standard Air Conditioner setup?
A. Air conditioners make your home cooler by using a compressed refrigerant to collect heat from inside your home as air passes over the coil in the air handler and pumping it outside. A heat pump, in cooling mode, does the same job. It is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space depending on local weather conditions. The efficiency of both heat pumps or central A/C units depends greatly on professional installation and maintenance of your system and properly sealed ducts with correctly matching of the size of your unit to the cooling load of your home.
Q: What is the FDD diagnostics system and how does it provide both value and savings for energy and equipment maintenance costs?  
A: Once the FDD module is properly activated and setup, the FDD system automatically provides alerts for customer’s home efficiency improvement, each potential fault and key components starting to fail or component fault/failures. Additionally, if a repair technician would need to be sent out only one visit is done since the tech will know what repair is needed and will bring in the exact part to finish up the repair.


Q: How long does it take to install a new system?
A: On a normal replacement of an existing system, it takes one day. Installation of a new system into a home without any existing equipment issues or custom repairs or upgrades as the installer confirms, it depends on the complexity of the system and the present condition of the house and ductwork components.  Any of our InverterCool installers should be able to approximate the length of time required to install the new heat pump system.


Q. How often should I change my air conditioner filter?

A. This depends on the type of filter that you have. We recommend that all filters be checked regularly every month to ensure efficient equipment operation. Standard 1” throw-away filters should be changed out monthly, keep them clean. The regular changing out of filters is a way more cost effective and healthier option compared with the cost of parts & labor for a compressor or blower motor should any of these parts be in need of repairs.

Q. What maintenance is required?

A. Like all mechanical equipment heat pumps need to be cleaned and maintained. You will simply need to clean the screen filters monthly. We recommend a full deep cleaning of the indoor and outdoor coils at least every other year to maintain efficiency, life span, and warranty on a heat pump system. Treat these systems just like your car when you schedule your tuneups. Cars don’t run well with dirty air, fuel, and oil filters and the same is true of a heat pump’s filters and coils.

Q. How long will my heat pump last?

A. There are many factors that contribute to a heat pump’s lifespan and overall performance — maintenance schedule, how often filters are changed and proper installation are just a few. Location and operational hours may also impact the longevity of a heat pump.For example, if you live in an area with long, cold winters, a heat pump will run more than in temperate climates. The same goes for warmer climates.
