Shipping policy
Effective Date: February 24, 2026
This Shipping Policy explains processing times, delivery estimates, tracking, and what to do if a shipment is delayed or arrives damaged.
1) Shipping coverage
We ship to U.S. addresses. Certain products may be restricted due to carrier rules, size/weight, or destination access.
2) Processing time
Most in-stock orders are processed within 1–2 business days (Mon–Fri, excluding holidays). If an item needs additional handling time or becomes unavailable, we’ll notify you.
3) Delivery estimates (after dispatch)
- Standard: typically 4–7 business days
-
Expedited: typically 2–5 business days (if offered at checkout)
Delivery windows are estimates and can be impacted by weather, peak seasons, or carrier delays.
4) Tracking & split shipments
Tracking is emailed when a shipping label is created. Carrier scans may take up to 48 hours to appear. Multi-item orders may ship in separate packages with multiple tracking numbers.
5) Address accuracy
Please verify your shipping address and contact number at checkout. Returned shipments due to address issues may require reshipment fees.
6) Delivery problems
If your package is missing, damaged, or significantly delayed, email help@sayitdeals.us within 7 days of delivery (or expected delivery date) with your order number and photos if applicable.
TECHNICAL PRODUCT SUPPORT
Refrigerant Questions, Answered.
Not sure about compatibility, cylinder sizing, charging or refrigerant selection? Here are answers to some of the most common technical questions customers ask before ordering.

A2L Safety
System Identification
01 How do I know which refrigerant my system requires?
Start with the equipment data plate or the manufacturer's service documentation. It should identify the approved refrigerant, such as R410A, R32, R454B, R404A, R407C, R448A, R22 or R134A.
Important:
Match the exact refrigerant designation specified for the
equipment. Similar applications do not mean the refrigerants
are interchangeable.
02 Can R410A be replaced with R32 or R454B?
Not simply by changing the refrigerant. R410A, R32 and R454B have different operating characteristics and equipment requirements.
R32 and R454B are also classified as A2L refrigerants and equipment designed for them incorporates requirements that may differ from equipment designed around R410A.
Only use a refrigerant that the equipment manufacturer specifically approves for that system.
03 What is the difference between R32, R454B and R410A?
All three may be encountered in air-conditioning and heat-pump applications, but they are different refrigerants and should not be treated as direct substitutes.
- R410A: widely used in many existing residential and commercial A/C systems.
- R32: used in newer equipment specifically engineered for R32.
- R454B: used in newer systems designed and approved for R454B.
Always follow the refrigerant designation shown on the unit rather than choosing based only on the type of equipment.
04 Can two different refrigerants be mixed in the same system?
No. Different refrigerant types should not be mixed unless a specific manufacturer-approved service procedure explicitly calls for it.
Mixing refrigerants can alter operating pressures, temperatures and performance, complicate recovery and make proper servicing difficult.
Never use a different refrigerant simply because the original
refrigerant is unavailable.
05 What does the cylinder weight actually mean?
A product listed as a 25 lb or 30 lb cylinder normally refers to the refrigerant's stated net contents rather than the total shipping weight of the cylinder.
The complete package will weigh more because the cylinder, valve and packaging add additional weight.
Always refer to the product label for the exact net contents of the cylinder you receive.
06 Does one cylinder equal one complete system charge?
Not necessarily. Refrigerant charge requirements vary significantly depending on the equipment, capacity, line-set length and system design.
The required factory charge is normally shown on the equipment data plate or in the manufacturer's installation and service documentation.
Best practice:
Determine the required charge before ordering rather than
assuming a cylinder corresponds to a certain number of systems.
07 Should refrigerant be charged by pressure or by weight?
The correct charging procedure depends on the equipment and manufacturer instructions.
Refrigerant weight is commonly an important part of the charging process, while operating measurements such as superheat, subcooling, temperature and pressure may also be required depending on the system.
Manufacturer service information should always take priority over a generic charging rule.
08 Why do refrigerants operate at different pressures?
Every refrigerant has its own pressure-temperature relationship. The pressure expected in a system therefore depends on the refrigerant, system conditions and operating temperatures.
This is why pressure readings from one refrigerant should not be used as a reference for a different refrigerant.
Service gauges, hoses and other equipment must also be
appropriate for the refrigerant and pressures being serviced.
09 What tools are normally used when servicing a refrigerant system?
Professional service work may require equipment such as:
- Refrigerant-compatible gauges
- Properly rated hoses and fittings
- Refrigerant charging scale
- Vacuum pump
- Micron gauge
- Leak-detection equipment
- Recovery machine and recovery cylinder
- Temperature measurement tools
Systems using A2L refrigerants may require tools and procedures specifically suitable for A2L service.
10 What should be done if a system has lost refrigerant?
Refrigerant loss can indicate a leak. Simply adding more refrigerant without determining why the charge was lost may leave the underlying problem unresolved.
A qualified technician should evaluate the system, locate and address leaks when required, confirm system integrity and recharge according to the manufacturer's service procedure.
11 How should refrigerant cylinders be stored?
Follow all instructions printed on the cylinder and supplied by the refrigerant manufacturer.
Cylinders should generally be protected from excessive heat, physical damage and unauthorized handling and kept in an appropriate, well-ventilated storage location.
Additional precautions apply to refrigerants with flammability classifications such as A2L products.
12 Can R22 still be used in older equipment?
Existing equipment originally designed for R22 may continue to require R22 or an approved retrofit solution during service.
Refrigerant selection should be based on the equipment, manufacturer guidance, applicable service procedures and current regulatory requirements.
Do not install a replacement refrigerant into an R22 system solely because it appears to have similar operating characteristics.
13 What does A2L mean on refrigerants such as R32 and R454B?
A2L is a refrigerant safety classification associated with lower flammability characteristics compared with more highly flammable refrigerant classes.
Equipment intended for an A2L refrigerant is designed around applicable safety requirements. Technicians should use appropriate procedures, tools and equipment when working with these systems.
Never place an A2L refrigerant into equipment that was not
designed and approved for it.
14 Do I need technician certification to purchase refrigerant?
Refrigerant intended for use in stationary refrigeration and air-conditioning equipment is subject to U.S. EPA refrigerant sales requirements.
Section 608 technician certification or other qualifying purchaser documentation may be required depending on the transaction and intended application.
Customers are responsible for meeting applicable federal, state and local purchasing, handling, recovery and service requirements.
