Energy consumption in homes is largely determined by the efficiency of the HVAC systems that are in place. Many factors influence this consumption, and can depend on the sizing calculations made by the original HVAC services provider, the efficiency of the installed systems and the lifestyle of the homeowners.

A load calculation is a critical step and must take into consideration the volume of air that needs to be conditioned, the surroundings, the insulation of the home, temperature fluctuations in the geographical area of the installation and required humidity controls. An efficient HVAC services provider will have qualified and experienced experts who can make these calculations and come up with designs of systems that are just right for the home whose comfort levels need to be maintained.

Energy savings is also dependent on the energy efficiency of the equipment used, and the service providers will be able to provide a homeowner with many alternatives. The more efficient units will be expensive, but this must be balanced against the likely savings that can accrue from the reduced electricity bills. Savings can also be ensured with more attention to insulation, and efficient service providers will give the customers the right guidance in these matters. Often redoing insulation and checking door and window seals can lead to an HVAC system that works more efficiently. Manufacturers are required to get certification of energy ratings, and this makes it easier for customers to make a choice of the right equipment.

Lifestyle can also play a part in energy savings if you ensure that temperature settings are set to reasonable levels and equipment is switched off when homes are not in occupation. The choice of a service provider for HVAC equipment is also best made of those people who can provide you with regular maintenance of the equipment as this is one more factor that can help to reduce energy consumption.
