🔧 MRCOOL Dual Fuel System — Questions & Answers

What is a MRCOOL Dual Fuel System?

The MRCOOL Dual Fuel System combines a high-efficiency heat pump with a gas furnace to give you the best of both worlds — electric heating and cooling when conditions are mild, and gas heat when it’s more efficient. It’s a smart, energy-saving setup that automatically switches between electric and gas heat to keep your home comfortable and your energy bills low.

What makes the MRCOOL Dual Fuel System different from other systems?

The MRCOOL Dual Fuel System features a factory pre-charged “A” coil that comes ready to install with no refrigerant handling required. This means you can connect it using our DIY pre-charged line sets for a completely DIY refrigerant installation—no vacuum pump, gauges, or professional charging required. That alone can save you thousands of dollars in installation costs.

What outdoor units can I pair with the MRCOOL pre-charged “A” coil?

The pre-charged “A” coil is compatible with:

  • MRCOOL VersaPro (standard heat pump with heating and cooling)
  • MRCOOL Hyper Heat Series (heats without a heat strip, even in temperatures as low as -22°F)
  • MRCOOL Universal Series (high-performance, flexible installation options)

All of these can be matched with a gas furnace to create a full dual-fuel system.

What does “pre-charged” mean?

“Pre-charged” means the coil and optional line sets come filled with the correct amount of R-454B refrigerant from the factory.

The refrigerant is sealed inside quick-connect fittings, so when you attach the pre-charged line sets, the system automatically opens and seals without any risk of leaks or contamination. No HVAC license or tools required!

Can I install the system myself?

If you’re using DIY pre-charged line sets, the refrigerant portion is completely DIY. However, if you’re integrating the system with an existing gas furnace, you may want a professional to confirm proper electrical and gas connections for safety and code compliance. Many homeowners complete the bulk of the install themselves and bring in a pro only for final checks.

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

Absolutely. The pre-charged “A” coil is versatile — it can be installed with traditional copper line sets (by a professional) or with MRCOOL’s DIY pre-charged line sets for a no-hassle setup.

How much money can I save by installing it myself?

By using MRCOOL’s pre-charged components and line sets, you can save hundreds to thousands of dollars compared to hiring an HVAC technician for a traditional installation. You get professional performance at a DIY price.
