Heating That Respects Your Investment

The MRCOOL 95% AFUE furnace turns 95 cents of every fuel dollar into real heat for your home. With 90,000 BTU output and a constant-torque ECM blower motor, it delivers even temperatures without the energy penalties of older fixed-speed units. Aluminized steel inshot burners fire smoothly and reliably, while self-diagnostics log the last ten fault codes so your technician knows exactly what happened before they arrive. This is a vetted unit we'd trust in our own home — backed by a 20-year heat exchanger warranty and 10-year registered parts coverage.

No More Guesswork With Your Heating Dollar

No More Guesswork With Your Heating Dollar

Walk into any big-box store and ask about furnace efficiency — you'll get a shrug and a finger pointed at whatever's on the pallet. We test what we sell, and the MRCOOL 95% AFUE furnace earned its place here by converting 95% of fuel into actual heat. The constant-torque ECM blower eliminates the energy spikes of old fixed-speed motors, using up to a third less electricity while maintaining steady, even temperatures room to room. Every spec on this unit has been checked against real-world performance, not just the manufacturer's data sheet.

Diagnostics That Save You Time and Money

Diagnostics That Save You Time and Money

When something trips on a cold night, the last thing you want is a technician guessing. This furnace stores the last ten fault codes in memory — even through power interruptions — so whoever shows up already knows what happened. The slide-out blower design makes access simple, and left or right utility connections give your installer flexibility without costly modifications. It's the kind of craftsmanship that respects both your time and your wallet.

Warranty Coverage That Means Business

Warranty Coverage That Means Business

A 20-year heat exchanger warranty isn't marketing fluff — it's MRCOOL putting their metal where their mouth is. Combined with a 10-year registered parts warranty, this furnace is built to be a long-term investment in your home's comfort. The aluminized steel inshot burners resist wear, the unit complies with California's strict South Coast Air Quality standards, and an optional LP conversion kit means it adapts to your fuel setup. This is the kind of curated reliability that makes a real difference over twenty winters.

Will it fit your installation space?

The MGD95SE090C4XA uses standardized widths for easy coil fit and offers flexible utility connections. Confirm your dimensions with your HVAC contractor before ordering.

  • Left or right utility connections for flexible placement
  • Removable floorbase for bottom return air configurations
  • Zero-step horizontal conversion for multi-position installs
