AC Unit Replacement is a Big Investment. What Are Your Options?

In the past several years, air conditioner technology has changed considerably. From added technology and options on traditional split systems to new products offerings including ductless and geothermal technology, which system is best for your home? Learn more about these popular heating and AC units:

Split Air Conditioning Systems (Heat Pumps)

Split systems get their name because they pair an indoor unit within the home with an outdoor unit. These heat pump style systems use refrigerant, coils, and a compressor to transport warmed/cooled air, alongside a fan to distribute it via ductwork. They are incredibly energy efficient, moving warm air into/out of your home depending on the season. Because the amount of heat available in the air is limited in colder regions, they are preferred in warmer regions, where a backup heat source (electric heat) is not needed. However, new technology in gas/electric unit combinations (below) now offers the best of both worlds.

Packaged ‘All-in-One’ Air Conditioning Systems

These systems also function via heat pump; however all the components in a packaged unit are contained in a metal housing outside your home.

Hybrid or Combo Systems

In frigid winter temperatures, heat pumps require a form of backup heat. In past system designs, this was typically electric heat, which fell short compared to the cost and performance of other heating options. Enter dual-fuel units, which now offer homeowners their choice of gas or electric heat output. As temperatures change in the colder months, they provide superior performance, saving money in the long-term by decreasing high energy costs.

Geothermal Systems

Geothermal systems are ground-sourced heat pumps. Using the constant temperatures found deep within the earth, they pump out more heating and air conditioning per dollar of energy consumed, costing 25-50% less to operate than conventional systems. They can also double to offer water heating in the summer, and pair well with radiant heating floor systems. The layout of your property and its geothermal characteristics determine geothermal installation. Growing in popularity due to climate change and energy efficiency concerns, they are an ideal choice for those seeking superior efficiency and a lower carbon footprint.

Ductless ‘Mini Split’ Systems

Mitsubishi ductless air conditioners do not need ducts to transport conditioned air, making them a favorite in homes with boilers for hot water heating that lack duct work and historic homes with limited space for AC components. They feature an outdoor unit paired with one or more indoor units, depending on home size. The indoor units are connected to the outdoor unit by small refrigerant lines. Each interior unit has its own thermostat and distributes air. This allows for zoned heating and cooling, helping you save energy by only heating/cooling the rooms you utilize. In addition to homes with hot water heating and historic homes, ductless systems are also useful for:

Adding heating/cooling to an addition.

Heating/cooling a basement or garage.

Providing independent temperature control in multiple home areas.
