Considering a High Efficiency HVAC System? Tips to Consider

Published on: May 9, 2012

When considering a high energy efficiency HVAC system for your Savannah, GA, home, there are a few factors to consider. Some of these factors include:


• The size of your home
• The amount of insulation you have in the walls and ceiling
• Whether or not you have windows with high energy efficiency ratings
• Whether or not your ducting system is maintained or has leaks
• The size of the HVAC system unit to be replaced.


Aside from price, the size of the unit should be considered first. Your local air conditioning company can recommend the right size unit for your home and budget. Too large of a unit will not keep your home cool efficiently. It will use too much power and run up the electric bill. A unit that is too small will run constantly and not cool the house. The bill will be through the roof.

The second factor is the SEER rating. It stands for seasonal energy efficiency rating. A unit with a 9 or 10 rating is low. The higher the unit is rated, the less energy it uses and the more efficient it is. Units are available today with ratings up to 24. Some units accept part of their power from solar panels, making them the most efficient on the market today. These units claim to save up to 60% on the energy bill. In Savannah, GA, this unit would pay for itself in a relatively short time.


The third factor is your HVAC system ducting system. No air conditioning system can be efficient if air is leaking into the attic or inside the walls. The moist air condenses in the attic and is absorbed by the insulation, rafters and roof decking. This causes mold, rot and failure of the insulation. When the leaks are repaired, the unit’s energy efficiency is higher. It does not have to compensate for the air loss.

Another factor is a maintenance contract. This is optional for the homeowner. Maintenance is mandatory to keep an HVAC system functioning at its best over time. The filter must be cleaned or replaced on a routine basis so air coming into the unit is clean and flows freely. The drain must be kept clear of algae by pouring a cup of bleach into it every month.


Other items such as the condensing unit require special maintenance. This is best performed by a professional. The technician can help you choose an HVAC system with the best energy efficiency ratings you can afford for your home.
