Description

The MRCOOL® Signature Series 48k Multi-Position Air Handler is a powerful and flexible solution for year-round home comfort. Engineered for performance and efficiency, this system works with R-454B refrigerant, offering a more environmentally friendly option that meets modern energy standards without compromising reliability.

Designed to adapt to your space, this air handler supports upflow, downflow, and horizontal installations, making it an ideal fit for a wide range of home layouts. When you’re dealing with limited space, its compact and streamlined design makes installation easy without sacrificing capacity. The cabinet exterior is outfitted with galvanized steel built to withstand wear, along with an interior ECM blower motor that delivers steady airflow while helping reduce energy consumption. The copper “A” coils and aluminum fins provide efficient heat transfer, while thermal insulation along the inside of the cabinet helps reduce condensation accumulation and improve overall system efficiency. Setup is straightforward, cutting down on labor time and cost. Maintenance is just as simple, thanks to the air filter rack, and an optional electric heat kit is available for enhanced heating in colder regions.

For added convenience, this system pairs effortlessly with most third-party smart thermostats, giving you full control over your comfort without being tied to a specific platform. Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 48k Multi-Position Air Handler delivers reliable, efficient comfort season after season.

Easy to install and working great.

I needed to replace another unit that a previous contractor didn't do any part of that installation correctly, and the condensation line was leaking inside the house, running down the wall since that installation!! The indoor coil was 1-1/2" out of level, the line set wasn't wrapped, the electrical was tapped into the same circuit as the garage light and outlets...it was a mess.

It took me more time to demo the old unit out than to install the one I bought from you.

Thank you.

Very pleased.

Very pleased with the price, delivery, ease of installation, and above all during this heatwave it is working excellently.

Perfect for our needs!

I ordered a 2 zone unit for the bedrooms in our home. It took a few months to arrive (manufacturer issue, nothing to do with HOD, and we were contacted on more than one occasion with an order update which was much appreciated!), but when it did arrive was very easy to install. Both the heat and AC function work perfectly, and our family is very happy!

Decent Company

I ordered a HVAC system and it arrived in a timely manner and with no apparent issues. I thought the system was defective once installed but it was the installers fault who wired it wrong. My only issue would be the fee (30% I believe) to return a defective item within the 30 day return policy. If it is defective the customer shouldn't have to pay a fee to return an item that is not operating as designed. Other than that this is a good company.

Pretty Easy Install and Works Great!

Installed my own central HP system. It was a bit of work but nothing beyond a person with basic mechanical and electrical skills. It took me a while because I had to remove the existing electric forced air furnace from a pretty tight place. Some custom sheet metal work and a bit of custom electrical too. Worked perfectly when powered up and I actually like the thermostat provided, although I wish it was clearer how to set up a temperature set-back schedule. Pre-charged refrigerant piping was something new and I liked that too. The best thing is that my electric utility forked out $4,000 and that paid for the unit!
