How much of your day is give and take? Going to bed early eliminates time with friends or family who stay out later. Eating fast and cheap doesn’t lend itself well to being healthy. When it comes to HVAC, you're often settling for bulky outdoor condensers to enjoy stable indoor temperatures. With the new MrCool Monoblock, you don’t have to give up outdoor space for a bulky condenser to gain customizable temperatures. You don’t have to exchange indoor comfort for a blight on your outdoor aesthetic. That means no more large condensers or ugly, boxy grates. For those of us living under the scrutinous watch of an HOA (Homeowners Association), the common complaint of HVAC condenser eyesores is about to become a thing of the past! MrCool’s newest MTHP series is a plug-and-play, ductless heating and cooling solution that is as pleasing to look at as it is to use. From your home office or gym to the detached garage, having a heating and cooling solution that won’t leave you footing the bill for an HOA fine is a game-changer!

No Outdoor Condenser? No Problem!

In the past, homeowners or landlords looking for a zoned climate control solution were likely to opt for a wall or window unit or a ductless mini split. While these are all still viable solutions for targeted heating and cooling, so much so that we just wrote about use-cases for ductless mini splits and window units, the ductless MrCool Monoblock MTHP series makes the choice simple. If you need a solution that supports multiple rooms with unique needs per zone, a multi-zone mini-split is the perfect fit. For any other scenario where you want better climate control in a single room or area, the MrCool Monoblock is the minimally intrusive solution you need.

Unlike through-the-wall and window unit air conditioning systems, the Monoblock doesn’t ruin the carefully curated aesthetic of your home’s exterior. The easy-to-miss 8” diameter openings used for venting and single drain tube extrusion are minimally invasive, unlike older, bulkier units that jut out the other side.

Quiet Operation, Low Maintenance

When MrCool says their Monoblock runs quietly, what does that actually mean in practice? Operational sound levels of the Monoblock highlight how quietly the hardware operates on the minimum and maximum settings. The lowest setting has an operational sound level of 32 dB, a volume roughly on par with the ambient noise level found in a quiet rural area. From there, the noise level slightly climbs with each power step up you take. When running the unit on its highest setting, the MrCool Monoblock maintains sound levels hardly louder than bird calls or the hushed ambient sounds you hear in a library at 46 dB.

For reference, 70 dB (decibels) is the arbitrary base of comparison when talking about how loud a sound is. Some people find sounds that are in the upper 70s annoyingly loud, while being exposed to sound levels at 80 dB or higher often leads to hearing loss over time. Think about some of the best applications for the MrCool Monoblock: guest rooms, sunrooms, garages, sheds, and hobby or game rooms—spaces where loud, intrusive HVAC sounds may leave you frustrated or unable to use the room as intended. Since a vacuum cleaner clocks in at the standard 70 dB threshold, hardware with a functional sound level dozens of decibels lower makes for a quiet permanent climate control solution.

The impressive features don’t end at sound levels; landlords and homeowners alike will love the MrCool Monoblock for its sleek, hidden installation. While many tenants can’t drill the two 8” holes through an exterior wall on their own, property owners can ensure their renters have access to truly customizable climate control in any unique zone with minimal work, thanks to the plug-and-play setup of the 115V electrical connection once the exhaust holes are handled. Between the self-evaporation system that removes moisture at a rate of 2.5 pints/hour and the included drain tube that’s installed during the do-it-yourself setup process, the inner workings are kept safe from condensation build-up for lasting performance.

Pro tip: If you work in a field that requires live audio recording, such as music tracking, sound fx, or voice capture for games, audiobooks, podcasts, etc., the MrCool Monoblock runs at a sound level quiet enough to easily eliminate as part of the room tone if captured during recording!

Simple, 3-Phase Installation

When you think of a do-it-yourself HVAC installation, your mind probably jumps to MrCool’s DIY Mini Splits. It should be no shock, then, that the Monoblock can be set up without the support of a professional, too. After all, MrCool is the brand that made HVAC approachable.

The MrCool Monoblock sports a streamlined, 3-phase installation. While there’s plenty of nuance in practice, the process breaks down to simple steps:

1. Pick a location for installation
2. Cut wall openings for the vents
3. Seal and mount the unit

Requiring only basic parts and tools for installation, such as a level, pencil, drill, 8-inch core bit, and knife. The time and effort MrCool puts into making HVAC installation accessible is evident.
