MRCOOL Dual Fuel Heat Pump & Furnace FAQ

Quick answers to common questions about MRCOOL dual fuel heat pump and furnace systems, including sizing, installation, and how the DIY pre-charged system works.

What is a MRCOOL Dual Fuel System?

A MRCOOL Dual Fuel HVAC System combines a high-efficiency heat pump and a gas furnace to provide year-round comfort and maximum energy efficiency.

During mild weather, the heat pump handles heating and cooling, using electricity to efficiently move heat in or out of your home. When temperatures drop and a heat pump becomes less efficient, the system automatically switches to the gas furnace for powerful and reliable heating.

This hybrid approach allows homeowners to enjoy:


  • Energy-efficient heating and cooling

  • Lower energy costs

  • Reliable performance during extreme cold

  • Smart automatic switching between heating sources

MRCOOL dual fuel systems are an excellent option for homeowners who want the efficiency of a heat pump and the dependable heating of a gas furnace.

How do I choose the right size MRCOOL Dual Fuel HVAC system?

Choosing the correct system size is important for both comfort and efficiency. HVAC systems are typically sized in BTUs (British Thermal Units) and are matched to the square footage and insulation characteristics of the home.

General guidelines include:

  • 2 Ton System – typically suited for smaller homes or spaces around 900–1,200 sq ft
  • 3 Ton System – common for homes around 1,200–1,800 sq ft
  • 4 Ton System – used for larger homes around 1,800–2,400 sq ft
  • 5 Ton System – suited for very large homes or open floor plans

However, the correct system size can also depend on factors such as insulation, ceiling height, climate zone, and home layout.

If you're unsure which system is right for your home, our team can help you select the best MRCOOL dual fuel heat pump and furnace system for your application.

Why choose a dual fuel HVAC system instead of a heat pump alone?

A dual fuel HVAC system provides the efficiency of a heat pump while maintaining the powerful heating capability of a gas furnace when temperatures drop.

Heat pumps are extremely efficient in mild and moderate temperatures, but their efficiency decreases as outdoor temperatures get very cold. A dual fuel system solves this by automatically switching to the gas furnace when it becomes more efficient to use gas heat.

This hybrid setup allows homeowners to benefit from:

  • Energy-efficient heating during mild weather
  • Reliable gas heat during extreme cold
  • Lower overall heating costs
  • Automatic switching between heating sources

MRCOOL dual fuel systems combine the advantages of both technologies, providing a balanced heating solution that works efficiently across a wide range of climates.

What makes MRCOOL Dual Fuel Systems different from other systems?

MRCOOL dual fuel systems are unique because the A-coil and condenser can be installed using MRCOOL DIY pre-charged line sets.

These factory-sealed line sets contain the correct refrigerant charge and use quick-connect fittings, allowing the heat pump side of the system to be installed without vacuum pumps, gauges, or refrigerant handling.

This means homeowners can install the entire air conditioning / heat pump portion of the system themselves, saving significant installation costs compared to traditional HVAC systems.

Benefits include:

  • Factory pre-charged A-coil
  • Compatible with MRCOOL DIY quick-connect line sets
  • No refrigerant handling required
  • Much simpler installation compared to traditional systems
How much money can I save by installing the system myself?

Installation costs for traditional HVAC systems can range from $3,000 to $10,000 or more, depending on the complexity of the project.

By using MRCOOL’s pre-charged components and DIY line sets, many homeowners are able to complete much of the installation themselves and significantly reduce installation costs.

Even when a professional is used for certain parts of the installation, homeowners often save hundreds to thousands of dollars compared to a traditional fully installed HVAC system.

Can I use traditional copper line sets instead of MRCOOL DIY pre-charged line sets?

Yes. The MRCOOL pre-charged A-coil is compatible with both:

  • MRCOOL DIY pre-charged line sets
  • Traditional copper line sets

If traditional copper lines are used, the system will need to be vacuumed and charged by an HVAC professional just like a conventional HVAC installation.

DIY line sets are simply an easier option for homeowners who want to simplify installation.

Can I install the MRCOOL dual fuel system myself?

Many homeowners install the heat pump and cooling portion of the system themselves using MRCOOL DIY pre-charged line sets.

These line sets make it possible to install the refrigerant connections without specialized HVAC equipment.

However, when installing or connecting a gas furnace (natural gas or propane), installation requirements can vary depending on local codes and regulations.

In some areas homeowners are allowed to install gas appliances themselves, while other regions may require a licensed professional. For safety and compliance, it’s always recommended to follow local regulations and ensure gas connections are installed properly.

Many homeowners choose a hybrid approach where they complete most of the installation themselves and have a professional verify or complete the gas connections.

What does “pre-charged” line set mean?

A pre-charged HVAC component contains the correct amount of refrigerant from the factory and is sealed inside the equipment.

MRCOOL DIY systems use pre-charged quick-connect fittings that keep refrigerant contained until the connections are made. Once the line set is connected, the valves open and the refrigerant flows into the system automatically.

This eliminates the need for:

  • Vacuum pumps
  • Manifold gauges
  • Refrigerant charging
  • Specialized HVAC tools

It allows the heat pump portion of the system to be installed using a simplified DIY process.

What outdoor units can be paired with the MRCOOL pre-charged A-coil?

The MRCOOL pre-charged A-coil is designed to work with several MRCOOL heat pump systems, including:

  • MRCOOL VersaPro Series – high-efficiency heat pump systems
  • MRCOOL Hyper Heat Series – heating performance down to extremely low outdoor temperatures
  • MRCOOL Universal Series – flexible installation options for many home configurations

These outdoor units can be combined with a high-efficiency gas furnace to create a complete dual fuel HVAC system.

How much does a MRCOOL Dual Fuel heat pump and furnace system cost?

The cost of a MRCOOL dual fuel heat pump and gas furnace system can vary depending on the size of the home, system capacity, and equipment configuration.

In general, MRCOOL dual fuel system bundles typically range between $3,000 and $6,000 for equipment, depending on the size of the system and included components.

Traditional HVAC installations can cost significantly more once labor, refrigerant charging, and installation fees are added. Because MRCOOL dual fuel systems can be installed using DIY pre-charged line sets, many homeowners are able to reduce installation costs substantially.

By completing part of the installation themselves, some homeowners save thousands of dollars compared to traditional HVAC installations.
