If you currently own, or are in the market for, a tiny house, then you might be wondering what heating and air conditioning systems are best for this type of home. With so many different types of HVAC units, it can be difficult to determine which one will meet your needs. We’ve identified the two best heating and air conditioning options for tiny houses and have provided a bit of information about each kind of unit.

In Wall Heater and Air Conditioner – Tiny House

If you’re in the market for a tiny house heater and air conditioner, a wall-mounted HVAC might be the best option. These units should be installed by an HVAC professional and are relatively inexpensive. The downside of these systems is that they are less energy efficient than other units and can be relatively loud, which may not be ideal for smaller spaces. If you are looking for a budget-friendly choice, however, an in-wall unit might be the best option.

Ductless Mini Split System

Mini split systems are some of the most popular heating and cooling options for tiny houses. They are more expensive than in-wall units, but they carry with them some hefty benefits. They are energy efficient, less noticeable, and have zoning capabilities. These units do cost more than in-wall units; and they will require an HVAC professional to install them as well.

Other considerations

It is critical that the air conditioning and heating system be sized appropriately for the space they will be installed in. Factors such as the number and size of windows, how they are constructed, and insulation levels will all determine how large a system you need. You want to avoid oversizing the air conditioning system. An HVAC system that is too large will short cycle on and off which is bad for the equipment, cost more in energy usage and does not remove humidity from the indoor air properly. This will result in high humidity levels and mold and mildew growth in your tiny space.

Your first thought might be to simply buy a window unit ac system from a big box home improvement store. We highly recommend not doing this. This could lead to poor comfort levels, dangerous mold growth in the tiny space and the window unit, and chronic health related issues from mold. Indoor mold infestations will cause illness that sometimes appear as neurological disorders.

As you start researching which HVAC system is right for your small space, we highly recommend you enlist the help of a licensed and trained HVAC professional. They can not only provide you with some advice, but they can also install your unit as well.
