The MRCOOL® 2.5-3 Ton Pre-Charged A-Coil is built to simplify installation and deliver dependable comfort for a wide range of HVAC applications. Designed to pair perfectly with most R-454B systems with No-Vac® Quick Connect® line set or a flare to sweat connections—this coil is an ideal choice for both retrofit projects and new setups.

Pre-charged with environmentally friendly R-454B refrigerant, this coil meets today’s climate-conscious standards. R-454B offers a significantly lower Global Warming Potential than older refrigerants, helping reduce your home’s environmental impact without sacrificing performance.

The factory charge also eliminates the need for field-charging, cutting down on installation time, labor costs, and complexity. Compact and adaptable, the MRCOOL Pre-Charged A-Coil supports upflow, downflow, and horizontal applications, making it easy to install in tight or unconventional spaces.

It features dual front drains for flexible utility connections, built-in side drain pan for horizontal configurations, and an A2L leak detection sensor as an additional safety measure—each detail is designed with homeowner and contractor convenience in mind.

Constructed with CoolGuard® corrosion-resistant aluminum, the coil is engineered for long-lasting performance, even in tough operating conditions. Its durable build helps extend system life and reduce maintenance needs over time.

Backed by a 10-year limited parts warranty, the MRCOOL® 3036-B Pre-Charged A-Coil offers homeowners and contractors a reliable, energy-efficient solution that delivers season after season. It’s the smart way to upgrade your system while saving time, energy, and installation effort.

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!
