These are estimates, not guarantees. We do not warehouse equipment ourselves — your order is placed with the manufacturer once you buy, and most items are released for shipment within 1 to 3 business days. If your item is on back-order, or the manufacturer confirms a longer lead time, we will contact you promptly and you may cancel for a full refund with no fee.

Standard shipping (free on every order) is curbside or dock-to-dock delivery to a commercial address in the 48 contiguous states and DC, or parcel delivery for smaller items. We are not currently set up to ship to Alaska, Hawaii, Puerto Rico or other US territories. Liftgate, residential, limited-access and inside delivery, rigging and crating are not included — typically $150 to several hundred dollars, quoted in writing and charged only with your prior approval.

Freight deliveries require a scheduled appointment and someone must be present to sign. Need a firm date before you buy? Call (720) 575-1376 or email support@techforgedirect.com with the model number.

Shipping Cost

Free standard shipping on every order to the 48 contiguous states and DC. No minimum order and no shipping charge at checkout.

What is your Return Policy?

30 days to request a return from the date you receive your order. Email support@techforgedirect.com with your order number and reason. We will assess your request and, once approved, send you an RMA number and detailed instructions. Do not ship anything back before you have an RMA number.

1. Return shipping costs

You as the customer are responsible for paying the return shipping costs of the items in your order. On freight-shipped machinery this can be substantial — we quote the exact amount in writing before you commit, so you decide with the full figure in front of you.

2. Preparing your return

Parcel-sized items: we email you a return label, and its cost is deducted from your refund. Freight items are collected under a bill of lading we arrange. The item must be unopened, unused and in delivery condition, including all original packaging and accessories, in a condition such that it can be re-sold as new. Machinery must not have been wired in or powered on. Photographic evidence is required.

3. Restocking fee

Change-of-mind returns carry a 25% restocking fee, deducted from your refund. On a $10,000 machine that is $2,500.

4. Damaged or incorrect products

Note it immediately when signing for delivery and send photographs to support@techforgedirect.com the day of delivery. We will ensure you get the correct product you ordered, undamaged, as soon as possible, at no cost to you — no return shipping charge and no restocking fee.

5. Refunds

Processed within 7 business days of your returned item being received and inspected.

6. Cancellations

Cancel any time before your order ships for a full refund with no fee.

Product Description

MRCOOL® Signature Series R-454B Air Handler

The MRCOOL® Signature Series Air Handler delivers dependable, energy-efficient comfort in any season. Built for R-454B refrigerant, it supports cleaner standards while helping to lower energy costs. When paired with a Signature Series heat pump or air conditioner condenser, it provides powerful, year-round heating and cooling.

Multi-Position models install in upflow, downflow, or horizontal positions, and their compact design fits easily into attics, closets, or crawl spaces. Stud Mount models are slim, space-saving units built to fit cleanly between standard wall studs, ideal for apartments, condos, and smaller homes.

Each air handler features a durable galvanized steel cabinet, a high-efficiency ECM blower motor, and copper coils with enhanced aluminum fins for optimized heat transfer and humidity control. Internal thermal insulation minimizes energy loss and condensation. A built-in filter rack makes maintenance quick and convenient, and an optional electric heat kit adds supplemental heat for colder climates. The unit works with most third-party thermostats.

Backed by a 10-year limited parts warranty.

Professional installation by a licensed HVAC technician is required.
