The Ultimate Guide to Cold/Heat Air Conditioners

Welcome to our comprehensive guide on cold/heat air conditioners! Whether you're looking to keep cool during the hot summer months or stay warm in the winter, a cold/heat air conditioner, also known as a heat pump, can be a versatile and efficient solution. This guide will explore how these systems work, their benefits, types, and tips for choosing the right one for your home or office.

What is a Cold/Heat Air Conditioner?

A cold/heat air conditioner is an HVAC (Heating, Ventilation, and Air Conditioning) system that can both cool and heat your space. Unlike traditional air conditioners that only cool, or furnaces that only heat, these systems offer dual functionality, making them ideal for year-round climate control.

How Do Cold/Heat Air Conditioners Work?

These systems use a heat pump to transfer heat between the inside and outside of your home. In cooling mode, the system extracts heat from the indoor air and releases it outside. In heating mode, it reverses the process, extracting heat from the outdoor air (even in cold temperatures) and bringing it indoors. This process is made possible through the use of a refrigerant and a reversing valve, allowing the system to switch between heating and cooling modes.

Benefits of Cold/Heat Air Conditioners

Energy Efficiency

Heat pumps are known for their energy efficiency. Instead of generating heat, they move it, which can be more efficient than traditional heating methods. High SEER (Seasonal Energy Efficiency Ratio) ratings, like the 16 SEER rating found in many Everwell models, indicate excellent energy performance.

Cost Savings

Due to their energy efficiency, cold/heat air conditioners can result in significant cost savings on your energy bills. While the initial investment might be higher than a traditional air conditioner or furnace, the long-term savings make them a cost-effective choice.

Year-Round Comfort

With a cold/heat air conditioner, you get a single system that provides comfort throughout the year. This eliminates the need for separate heating and cooling systems, saving space and simplifying maintenance.

Environmental Impact

Heat pumps use electricity rather than fossil fuels, reducing your carbon footprint. Modern refrigerants like R410A used in Everwell systems are also more environmentally friendly than older refrigerants like R22.

Types of Cold/Heat Air Conditioners

Minisplit Systems

Minisplit systems, like the Everwell Minisplit Cold/Heat Air Conditioner with 24,000 BTU capacity and a 16 SEER rating, are ideal for homes without ductwork. They consist of an outdoor compressor and one or more indoor air-handling units. Minisplits offer flexibility and easy installation.

Central Split Systems

Central split systems are suitable for larger homes or commercial spaces. They use ductwork to distribute air throughout the building. Everwell's Inverter Central Split System is a powerful option, offering 48,000 BTU capacity and a 17.5 SEER rating for high efficiency.

Packaged Systems

Packaged systems contain all components in a single outdoor unit, making them a good choice for homes with limited indoor space. They are easy to install and maintain, providing both heating and cooling from one unit.

Choosing the Right Cold/Heat Air Conditioner

Determine Your Needs

Consider the size of the space you need to heat and cool, your climate, and your budget. Larger spaces or extreme climates may require higher capacity units.

Look for Efficiency Ratings

Higher SEER ratings indicate better energy efficiency. Look for units with high SEER ratings to maximize your energy savings.

Professional Installation

Ensure your system is installed by a certified professional to guarantee optimal performance and efficiency. Proper installation can prevent issues and extend the life of your system.

Maintenance Tips

Regular Filter Cleaning/Replacement

Clean or replace air filters regularly to maintain airflow and efficiency.

Check Refrigerant Levels

Ensure refrigerant levels are appropriate and there are no leaks.

Schedule Annual Maintenance

Have a professional technician inspect and service your system annually to keep it running smoothly.


Cold/heat air conditioners offer a versatile, efficient, and cost-effective solution for year-round climate control. Whether you opt for a minisplit system like the Everwell 24,000 BTU unit or a central system, you'll enjoy the benefits of consistent comfort and energy savings. Follow our tips for choosing and maintaining your system to ensure you get the most out of your investment.
