When purchasing a ductless mini-split, it almost always makes sense to get a heat pump for several reasons. The rebates and incentives being offered for heat pumps versus cooling-only units essentially pay you to do so. Another reason is that most local vendors exclusively stock ductless heat pumps and do not stock cooling-only units. If the two are essentially the same price, but you can get both cooling and heating (base models as low as 5 degrees and advanced models at 15 degrees below zero outside) from a heat pump, but only cooling from an air conditioner, why would you not pick a heat pump? Heat pumps in a central system, however, can only work in outside temperatures as low as 25-30 degrees, which is not enough heat for regions with blistery winters like New England. Rebates and incentives for central heat pumps are harder to come by, and the equipment can be expensive. If your only fuel source is propane, oil, or electric heat, then you could reduce your energy costs by setting up a hybrid duel-fuel system with a heat pump.

If you are looking for a more efficient cooling option without using ductwork or window space, then ductless mini-splits are perfect for you. Since all we need to do is mount the indoor and outdoor units with the refrigerant lines, drain, and electricity, you’re looking at a swift installation process. Most of these systems both heat and cool while producing the highest SEER ratings — which will save you a lot of money on your utility bills! In addition, local utility companies are always offering attractive rebates and incentives. Some of these systems can provide heat when it’s -15 degrees outside — perfect for New England winters. Unlike central air conditioning, each air handler can be zoned to a different temperature, particularly to the type of traffic that goes through each space. These systems heat and cool evenly and quietly. With several options available for air handlers–ceiling, wall, or floor-mounted–you can choose a unit that fits the design and decor of the space where it will be mounted.

Central air conditioning systems, whether traditional or high velocity, are known as split systems because the system is split as one indoor unit, usually a coil or air handler, and one outdoor unit (air conditioner or heat pump).

These are connected by control wiring with a condensate drain. The indoor system connects to a central ducting system and, through the use of a fan, distributes the conditioned air to each room through floor, wall, or ceiling registers. Since forced air systems are the preferred system for most new construction homes, central air is the most common system found cooling homes in the area— although ductless systems are trending in popularity. Like any forced air system, the quality of your air is dependent on the design and installation of your duct system.

Since air conditioning systems actually cool your house by removing heat in your space, you must not overlook your return ductwork. It is critical, then, to capture the heat load properly to keep you cool on the hottest days.
