LET'S GET STARTED

Rheem Wall Mount Air Handler

Rheem Concealed Duct Air Handler

STEP 1: Indoor Air Handlers

The first step in building your multi-zone system is determining how many zones you need. Once you have that, you need to know the approximate square footage of each zone. You will want to take into account ceiling heights, quality of insulation, total amount of windows (and which way they face) and a few other factors in order to properly size your system. For example, if you have ceilings taller than the standard 8ft, then you want to size-up a little. If you're putting the system in a sunroom that brings in a lot of daylight and heat, again you'll want to size-up a little bit.

The recommendations below are an average based on general factors, but for your specific application, please contact a state-licensed HVAC/R Technician for a complete load-calculation. Please review the details below about each of our available Rheem Indoor Units to help you make the right selections when building your multi-zone:

    • 7,000 BTU/H Wall Mount:  200-350 Sq. Ft.
    • 9,000 BTU/H Wall Mount: 300-500 Sq. Ft.
    • 12,000 BTU/H Wall Mount:  400-650 Sq. Ft.
    • 15,000 BTU/H Wall Mount: 500-800 Sq. Ft.
    • 18,000 BTU/H Wall Mount:  600-1,000 Sq. Ft.
    • 18,000 BTU/H Concealed Duct: 600-1,000 Sq. Ft.
    • 24,000 BTU/H Wall Mount: 800-1,300 Sq. Ft.

 

FIRST: Select Your Air Handlers (One Per Zone, No More Than FIVE Total per System)

STEP 2: Outdoor Condensers

Now that you have your individual zones figured out, let's find you a condenser that can handle the full load. You can connect anywhere from two to five indoor units, depending on the condenser model you select. This is important to note because you may want to install only two zones now, but might want to add a third, forth or fifth later. In those cases, you'll want to select a larger condenser that can handle the capacity for your long-term plans as well. Again, sizing comes into play, you want to make sure you have a condenser that provides enough BTU power to handle ALL the square footage you figured out above. Don't forget to size-up if you have those extenuating circumstances.  

The recommendations below are an average based on general factors, but for your specific application, please contact a state-licensed HVAC/R Technician for a complete load-calculation. The colorful chart to the right shows the allowable combinations as recommended by the manufacturer. Please carefully review this chart when making your selection to ensure that the system you are building is one of these recommended combinations. Please review the details below about each of our available Rheem Indoor Units to help you make the right selections when building your multi-zone:

    • 18,000 BTU/H Condenser:  Upto 1,000 TOTAL Sq. Ft - (2 Indoor Units Only)
    • 24,000 BTU/H Condenser:  Upto 1,300 TOTAL Sq. Ft - (2-3 Indoor Units)
    • 36,000 BTU/H Condenser:  Upto 2,000 TOTAL Sq. Ft - (2-4 Indoor Units)
    • 45,000 BTU/H Condenser:  Upto 2,500 TOTAL Sq. Ft - (2-5 Indoor Units)

 

NOW: Select Your Condenser
(Make sure the condenser you select can handle the zones you chose in the first step. Use the chart above to be sure.)

STEP 3: Let's Talk About Accessories

Selecting the right accessories can seem confusing, but we're going to make it as clear as possible here so stick with us. When in doubt, please feel free to contact our Product Experts for any assistance.

LINE SET KITS

Each air handler that you chose will require a Line Set Kit; so if you are making a 3-zone system, you need 3 different line sets. Additionally, each air handler has different size requirements for which line set it will need. You can use the chart on the right to make sure you are selecting the right SIZE for each of your air handlers. Now that you know which SIZE you need, now you need to determine what LENGTH you need to suit your application. Each line set size we offer comes in multiple length options. To figure the right length, you need to figure how many feet will be between each indoor unit and the outdoor unit. Make sure you're figuring how the line set will run along the wall and possibly around corners like this image.

OTHER ACCESSORIES

The Line Set Kit (mentioned above) is the one accessory required for every mini split installation. Below is a list of some of our other more popular mini split accessories that you may want/need. What you need will be specific to your application, but we'll walk you through each item and explain what it is and how it's used so you can determine if it's right for you. If you have any questions, our Product Experts are available to help at 855-337-0001.

Product Description Add to Order

Disconnect Switch

RECOMMENDED - A disconnect switch mounts in the wall and provides a physical power disconnect for indoor units. This accessory is REQUIRED by code in many geographical areas throughout the country - your local HVAC Technician will know if it's required in your area. We like the First America DFS-SWITCH-A because it's specifically built for mini split systems - we recommend this item on all systems, even if not required by law.

One per indoor unit.

HVAC Surge Protector

RECOMMENDED – A Ductless Mini Split is an investment in your home and your comfort – it’s very wise to protect that investment against those power surges that can kill your home appliances and turn into very costly repairs or replacements. We recommend the Intermatic AG3000 for our Ductless Mini Split Systems because it’s specific for Mini Split HVAC units, easy to install, reliable and rated for outdoor use.

One per outdoor unit.

Speedi-Channel Wall Sleeve

RECOMMENDED – This is simple sleeve that runs through the wall, where you need to insert your lineset, control wires and drain lines. This little piece just makes it cleaner and easier to run those lines through when completing the installation – without tearing up your drywall and making a mess – they’re also highly recommended for use with Stucco and Brick installations.

One per indoor unit.

Thread Sealant

RECOMMENDED - This product is an inexpensive add-on to ensure you're getting a tight seal at all your connection points to avoid leaks and prevent system failure down the line.

One per system.

Green Mini Strips

RECOMMENDED – With no harsh chemicals or biocides, we recommend the PurCool Green Mini Strips as a very inexpensive and environmentally friendly way to prevent slime and sludge build-up in your air handler – which will also assist in making sure the air that is circulating is cleaner. These strips last up to 6 months for large systems or can be cut in half for smaller tonnage evaporators giving you up to a year of protection.

One per indoor unit.


SOMEWHERE TO PUT YOUR CONDENSER

POSSIBLE – Often overlooked – where are you going to put your condenser? If you’re replacing an existing Mini Split, this is probably less of a concern for you. If you’re changing out central air for a Mini Split – then you likely have an existing concrete pad. Since condensers on Ductless Mini Split systems are so much smaller, this pad may be too large. Below is the information on the two options we offer.


See Below
about our
Condenser Pad
or Wall Bracket

* Plastic Condenser Pad

This Diversitech Outdoor Condenser Mounting pad is specially engineered to provide self-leveling support on the ground and has a textured surface to keep your condenser stable at all times. This pad is highly recommended for most applications as it is compact and lightweight, yet sturdy and designed specifically for your Ductless Mini Split.

One per oudoor unit.

* Wall Mount Bracket

This Diversitech sturdy bracket provides flexibility of installation for your mini-split condenser when ground space is not an option. The cross bar mounts directly to the exterior wall, and the L-shaped brackets are connected securely to it and the condenser, using bolts and vibration-proof washers provided with the system. This bracket is highly recommended for 2nd story applications, or in areas where winter snowfall can be excessive.

One per outdoor unit.


Condensate
Pump

POSSIBLE – By design, ductless mini split systems remove excess humidity from the air – potentially having the need to remove a lot of excess condensation. In many applications, a condensate Pump kit would be required and a welcome addition to assist in keeping your system dry – which in the long run, will help keep it clean. Most often, our customers add these pumps when gravity cannot be used to drain all of the condensation – or if your drain lines are long (to ensure they keep dry and avoid mold from growing). We recommend the following three ASPEN Pumps for ease of use and installation. Note – each one has a specific installation application.


See Below
about our
White,
Aqua
and Orange Condensate Pumps

Mini Aqua Condensate Pump Kit

This pump is our most popular and versatile kit – it can be used in systems that are less than 30,000 BTU’s. (Note, if you have a multi-zone system, size the pump to each air handler). This compact pump mounts inside the air handler and is extremely quiet. Conveniently, it can be added to your system even after your initial installation is complete, if it is decided that you need it later.

One per indoor unit.

Mini White Condensate Pump Kit

Like the Aqua pump, this kit is recommended for use with systems that are less than 30,000 BTU’s. This pump will mount on the wall near the air handler, but not internally to the system. This makes it extremely easy to install and especially great for ceiling suspended indoor units. We also love the snap-on/off cover for simple access to clean the filter.

One per indoor unit.

Maxi Orange Condensate Pump Kit

This pump is specific for systems that are 30,000 BTU’s and higher. Like the Aqua pump, it’s extremely quiet and mounts inside the air handler. This pump is designed for higher performance to give you more power when you need it.

One per indoor unit.

Condensate Drain Line

POSSIBLE– If you’re adding a Condensate Pump to your application, you’ll most definitely need additional drain line. Each system comes with anywhere from 12-30” of drain line in each air handler. Most applications will require additional drain line – even if you’re not using a pump. We recommend the inexpensive Diversitech 5/8” line and we offer it in 20’ lengths. We love this drain line because of its unique no-kink design and large diameter – also you can easily cut it down to size, or buy multiples and couple them together; very user friendly.

Recommended quantity varies based on application.

Mini Split Complete Care Kit

OTHER – This Mini Split Care Kit is the perfect set to keep your system running cleanly and efficiently. To avoid the buildup of dirt, grime, mold and mildew that can occur over time, this kit will clean, deodorize and disinfect your evaporator, as well as prevent overflows in your drain pan. The simplest way to maintain your system, we recommend using this kit at least once or twice a year.

One per system.

Rheem Warranty Specifics

STANDARD WARRANTY
The Rheem Residential Mini-Split Heat Pumps come with a standard five-year warranty for parts and a seven-year compressor warranty. Registration of installation is strongly recommended. Proof of proper installation by a state-licensed HVAC/R Contractor will be required in order to validate warranty eligibility. For full details and exclusions, please click here.

The REAL DEAL on HVAC/R Warranties

At ComfortUp we pride ourselves on outstanding customer service and superior product knowledge. We take the time to talk to our customers, build relationships and tell them like it is. That's why we're going to tell you that warranties on HVAC/R products stink! 

While it sounds great to have 5-year coverage, the manufacturer's warranty is there to protect the manufacturer, not the consumer. That's why you'll see that Labor Expenses are NOT covered under the manufacturer's warranty. This shortfall is not specific to Rheem, unfortunately it is an industry standard; parts are covered, labor is not. In the grand scheme of things, parts are cheap and you will pay dearly for labor expenses, even for a "warrantied" repair. This can be extremely frustrating in the midst of dealing with a system failure.  

Why are we telling you this? Don't get us wrong, Rheem makes a great product and 99.9% of the time, the systems work flawlessly when installed properly by a state-licensed HVAC/R Contractor. However, these are man-made products and while a system failure is not anticipated, they do sometimes happen.  

We want you to love and enjoy your Rheem Mini Split. That starts with getting a great price from ComfortUp, having it quickly shipped right to your location, and then having it properly installed by a state-licensed HVAC/R Contractor. To go a step further, ComfortUp offers Extended Product Warranties. Have peace-of-mind with 3, 5, 7 or 10-year Extended Warranty options. With no deductibles, you can rest assured that once your Extended Warranty is registered, you are covered for no further out-of-pocket expenses if a system failure should occur within your selected coverage period.
