Two-stage comfort
Two levels of heating or cooling output help your system respond to lighter and heavier demand, supporting more even indoor temperatures.
Compressor staging is different from furnace burner staging.EXCLUSIVELY FROM CATZ
Build your
comfort system.
Your home. Your priorities. Your options. Build your starting point in three simple steps: equipment, comfort options, then a conversation with CATZ.
Your choices stay with you as you move between steps. They are not saved after you leave this page.
Start with your system.
Explore a starting point. John can help you choose and answer questions; you do not need a final equipment choice. Not sure about size? Choose “I’m not sure.” This step does not send a request or schedule a visit.
Optional: understand efficiency and YORK technology
EXPLORE. UNDERSTAND. CHOOSE WITH CONFIDENCE.
Know what you’re upgrading
before you buy.
Cooling efficiency, heating efficiency, and comfort features explained separately, so you can see what actually changes.
Get to know the ratings ↓YORK TECHNOLOGY, IN PLAIN ENGLISH
Explore today’s YORK technology.
Look for the features that fit your priorities. Availability depends on the exact equipment and matched system, not the SEER2 number alone.
Inverter-driven comfort
A variable-speed compressor adjusts its output to changing heating and cooling needs, helping maintain steady comfort.
Examples: HH8 and YH9 outdoor heat pumps. Their control requirements differ.Variable-speed airflow
A variable-speed indoor blower adjusts airflow to support quieter circulation, more even temperatures and humidity control when paired and configured correctly.
This describes the indoor fan, not the outdoor compressor.Hybrid heating flexibility
Pair a compatible heat pump with a gas furnace for electric heating with gas backup when conditions call for it.
Compare both heating systems and how the controls choose between them.Which technology is in the combination I’m considering?
Open a combination below and inspect its exact models and listed blower and furnace-stage information. Features vary by model and matched system. CATZ confirms final equipment, controls and performance during system design.
Modulation and variable speed: an inverter-driven compressor varies its output. This does not mean its paired gas furnace has a modulating burner. The current catalog’s listed furnace stages are single-stage or two-stage. A multi-speed or constant-torque ECM blower is not automatically the same as a variable-speed blower.

Not sure about size?
Choose “I'm not sure” for help from CATZ.
Choose “I'm not sure” for help from CATZ.
Let's start with your home.
You don't need to choose a size today. A CATZ assessment can establish the home's heating and cooling load and the equipment fit. Square footage alone doesn't establish system size.
OPTIONAL HOME PROFILE
A little context. A better conversation.
Answer what you know and leave the rest as unknown. These details frame a CATZ assessment; they do not calculate equipment size or recommend a capacity. Use the part of your home served by the system being replaced, which may be smaller than the whole house.
These answers stay in this page while it is open. They are not saved or sent. Copying them into your conversation request is your choice.
What to discuss with CATZ
Your equipment size is still to be determined. A professional load calculation and installation assessment are needed to recommend a matched system.
Why sizing needs an assessment: U.S. Department of Energy · ACCA Manual J
EXPLORE YOUR OPTIONS
These are catalog equipment combinations to explore, not a final recommendation. CATZ must confirm sizing, equipment compatibility, availability and the installation details for your home.
Choose a size above to see equipment combinations, or choose “I’m not sure” for a CATZ assessment. No equipment capacity has been selected for you.
YOUR COMFORT SYSTEM STARTING POINT
Take a closer look.
Make comfort personal.
Tell John what matters to you. These optional interests are topics to discuss, not installation commitments. Choose what matters to you, or skip ahead; nothing is sent at this step.

LEARN ABOUT ZONING
Two ways to manage airflow.
A zone damper is a movable gate in a duct. When one part of the home needs heating or cooling and another doesn't, the system still needs a suitable airflow path.

3. Airflow paths: a conventional bypass redirects air; iO ESP partly opens selected non-calling zone dampers.

The main supply and return ducts stay. These are illustrative layouts, not installation plans. CATZ must assess ductwork, airflow, static pressure and equipment/control compatibility. This illustration does not confirm a match to your selected system.
PERSONALIZE THE CONVERSATION
Comfort and air-quality options to discuss
Choose any topics you would like CATZ to review. These are interest requests, not confirmed compatible products or approved installations. CATZ will confirm the right model, installation needs and price for your system.
Requests stay selected if you change systems. Their fit remains unverified until CATZ reviews the equipment and installation.

THE NEXT STEP
Start a conversation with John.
Copy your selections below, then continue to CATZ’s Housecall Pro form. Enter your ZIP code, choose Comfort Builder — Request a Conversation, and paste your summary into the first answer. Complete and submit the form to request John’s help choosing a system or answering questions.
0 / 1000 characters
Your selections do not transfer automatically. Copy and paste them into the form. Housecall Pro may use the labels “Book service” and “booking successful”; for Comfort Builder — Request a Conversation, submitting creates an unscheduled request. It does not reserve a home visit or commit you to an installation. Copying this summary or opening the form does not submit it.
What happens after you submit: John will contact you to discuss your selections and answer your questions. If a home visit is needed to confirm sizing or compatibility, we’ll arrange it with you.

Understand your protection, too.
10-year limited parts warranty on qualifying registered YORK® residential equipment.*
Coverage is model- and application-dependent. CATZ will confirm the written warranty for your exact equipment before your proposal. This is not a warranty for every option shown.
Registration, exclusions and model exceptions
*Registration is generally required within 90 days of installation, or closing for new construction. Standard parts coverage is generally 5 years without timely registration, except where law provides otherwise. Coverage depends on the product, purchaser, application, installation and maintenance requirements.
Manufacturer parts coverage does not include labor, refrigerant or routine maintenance. Accessories and optional protection plans have separate terms. Some equipment, including certain three-phase and ultra-low-NOx models, has different coverage. See the selected equipment’s written warranty.
