Rheem RD16 Dual-Fuel System Package

Heat-pump flexibility with gas heat available.

An RD16AY heat pump, compatible indoor coil, and gas furnace work together as a dual-fuel system. The heat pump provides cooling and electric heating; the furnace supplies gas heat according to the configured control strategy.

EcoNet thermostat included with this system.

Your RD16 or RD18 system includes a Rheem EcoNet thermostat. We explain the installed controls and settings during your system handover.

The indoor coil and controls

The compatible indoor coil and included EcoNet thermostat complete the equipment arrangement. Your proposal identifies the actual equipment models.

The components shown explain this package family. The approved written proposal defines the equipment and work included for your home.

UNDERSTAND YOUR OPTIONS

Who this is worth comparing for

Homeowners with gas service who want to compare a heat pump with a conventional AC replacement while retaining gas heat. It is especially useful to discuss how you use the home and what matters during both mild and colder weather.

What changes between the options

Dual fuel needs compatible equipment and controls. The changeover settings should reflect the application and comfort priorities; there is no single outdoor temperature or guaranteed savings figure that fits every home. We also compare it with the RD18 option.

What your written estimate will spell out

The exact capacity and model numbers, indoor/outdoor match, thermostat, installation scope, and applicable warranties belong on your proposal. Duct changes, electrical work, drains, venting, accessories, and labor coverage should be clear before you approve the job. An equipment-family page is not a substitute for that home-specific scope.

Efficiency without the guessing

We compare the certified rating of the actual matched system. SEER2 describes seasonal cooling; HSPF2 describes heat-pump heating; AFUE describes gas-furnace fuel conversion. These measure different things. A higher rating is not a guarantee of a particular bill or a fix for poor ductwork.

A SIMPLE LOOK AT ENERGY COSTS

What could you save each year?

Start with a 12-SEER system and see an approximate annual energy-cost difference. No technical measurements needed. Not sure about your system? Leave the example selected and we’ll help you refine it.

This estimates operating costs, not the right equipment size for your home.

Approximate yearly energy savingsCalculating…

For this illustration, heating compares your old gas furnace with the new furnace. Heat-pump heating and changeover settings are not modeled, so this is not a prediction of full dual-fuel operation.

Adjust the assumptions

Local rate examples are filled in. Change them if you know your utility rates or current equipment ratings.

How we estimate your savings

“Typical example” assumes 1,200 equivalent full-load cooling hours per year. Heating assumes the delivered heat represented by 600 therms through the selected existing furnace, or 30 million Btu of heat-pump output, for a 3-ton example. Loads scale with the selected size; lighter/heavier use is 25% below/above this example. These are illustrative assumptions, not measured Atlanta household averages.

We apply the selected verified equipment example’s efficiency to that load. Other sizes and equipment combinations can have different certified ratings; this is not a certificate for every size. Your proposal’s exact matched system determines the final rating. Legacy SEER and SEER2 use different test procedures; this screening estimate compares their numerical ratings directly and is approximate, not a certified conversion.

For this illustration, heating compares your old gas furnace with the new furnace. Heat-pump heating and changeover settings are not modeled, so this is not a prediction of full dual-fuel operation. Fixed utility fees, accessories, maintenance, installation cost, and financing are excluded. Weather, ducts, thermostat settings, and actual usage change results. Savings are not guaranteed.

WHAT TO EXPECT

Expert Service. A Personal Touch.

You should not have to decode a model number to feel comfortable with your decision. Tell us what your current system is doing, which rooms bother you, and what you want to improve.

We listen, explain what we find, and walk through the equipment and installation options. You see the scope and price before approving the work. When the job is finished, we check operation and explain the controls and care.

A few questions worth asking

Is this the exact system on my proposal?

This guide explains an equipment or package family. Your proposal identifies the actual models, capacity, accessories, installation work, and terms for your home. Ask us to walk through any difference.

Will a higher-efficiency system fix an uncomfortable room?

It may help, but airflow, duct condition, insulation, and sizing can also be involved. Tell us about the room before choosing the replacement so we can explain what the proposed work will address.

Can I compare payment options?

Yes. Ask us to explain available financing options alongside the equipment choices. Financing is subject to approval and applicable terms.
