With the higher temperatures comes a question -What cooling system will be most efficient and capable for your home?

Here is some valuable information to help in deciding which system is best.

Traditional Air Conditioning

  • If you already have ductwork, it may make sense to go with a traditional central air system. In most cases Conventional Central Air system can utilize existing ductwork for existing forced air heating system.
  • If you don’t like the look of the wall mounted ductless head units, Traditional central air units could be a cost effective option to condition your entire home – they are virtually invisible in the living space of your home.
  • Traditional ducted A/C systems offer excellent humidity control options with today’s variable speed fans that allow for proper dehumidification.

Ducted Heat Pumps

  • The system cools and heats home interiors
  • Low cost of operation compared to oil or electric systems
  • Keep in mind there may be a need for electrical upgrades to install ducted eat pumps and the old duct work may affect the level of efficiency.

Ductless Air Conditioning

  • If you're looking for a modern and energy-efficient solution for cooling your home, ductless system may be your effective, efficient and versatile solution.
  • Ductless is a good solution for additions, sunrooms, garages, etc. - areas that are not served by an existing central air system and cannot be be ducted in easily.
  • Ductless systems are easier to zone for different cooling needs in different parts of your home - allowing you to save energy and maximize personal comfort.
  • When properly sized, ductless systems are very efficient and comparable to, or more efficient than, traditional systems. Advanced ductless systems have a coefficient of performance (COP) between 250 and 300 percent - where COP is the ratio of heating/cooling provided compared to energy consumed.
  • Ductless systems may help reduce dust in the home through the reduction in space for mold and other allergens to collect. Filters are also not required for ductless units.
  • No air leaks through ductwork.
  • Ductless mini splits allow you to have total control in any room, section of the houseor your hole house.
  • One wall unit will not serve a whole home.

Inverter Technology

  • Rather than the typical starts and stops of traditional systems, inverter technology allows the compressor to operate at variable speeds, slowing and speeding up as needed to maintain a constant, comfortable temperature with minimal use of energy.
  • Inverter technology can be used as the primary heating and cooling solution for a home or in addition to oil or propane. Many ductless systems use this type of technology.

Multi Split Air Conditioners, Inverted or Heat Pumps

  • Multi-system options allow a single outdoor unit to be connected to several indoor units - this solves the problem of limited installation space and does not clutter the exterior of the home.
  • Offers zone control - determining the temperature of each individual room.
  • Increases efficiency with low energy consumption.

It is important to note that not all contractors are fully trained and knowledgable in ductless and inverter technologies and, if not properly sized or placed, these systems will not run as efficiently as expected. The same is true for traditional central air systems if improperly sized and installed.
