Dependable HVAC Installation in Montgomery

Published on: December 28, 2012

Choosing a new HVAC installation in Montgomery is a big decision. You want a heating and cooling system that will be able to keep your home comfortable without costing you a fortune to install. It is also important that your new system is not too expensive to run. Before you select an HVAC system for your Montgomery home, here are some things to consider.

Heating and Cooling Load

One of the most important factors to consider when having a new HVAC installation done is your home heating and cooling load. Your heating and cooling load represents the amount of power required by your HVAC system to keep your home at a set temperature. The higher your heating and cooling load, the more powerful and expensive your HVAC system needs to be. These loads are determined by the size of your home, the construction and the climate you live in. These loads are affected by the quality and quantity of your insulation, the condition of your air ducts and any gaps in your doorways and windows.

If you want to reduce the cost of your HVAC installation, you should look into reducing your heating and cooling load. The easiest way to do this is to have a home energy audit done. Home energy auditors will inspect your home from basement to attic looking for areas where heated air enters and exits your home. This is done mainly by using thermal imaging and blower tests. Once these areas are no longer letting heated air pass through them, your new HVAC system will have less work to do. This will allow you to purchase less expensive equipment and reduce your power bills.

Choosing Efficient Ductwork

Another consideration for your HVAC installation is choosing the best air duct system for your new HVAC equipment. You have the option of a standard duct system, HVAC zoning or a ductless system. It is likely that you have a standard duct HVAC system in your home now. With these systems, heated and cooled air is blown through air ducts and enters your home through vents. The downside of air ducts is that they often develop leaks that allow this air to escape. This wastes energy and can cause problems keeping all of the rooms in your home at the same temperature. 

HVAC manufacturers have developed HVAC zoning and ductless systems to help avoid this problem. HVAC zoning uses dampers installed in your air ducts to control the flow of air. These dampers regulate the flow of air through your ducts, ensuring the temperature throughout your home is the same. 

Another increasingly popular option is a ductless HVAC system. These systems completely eliminate the need for air ducts. Instead of heating and cooling air from a single air handler, several air handlers are installed in your home. These air handlers deliver heated and cooled air directly into different rooms in your house. They can also be set for different temperatures, reduced wasted energy. These systems are very easy to install and are an excellent choice for older homes with incomplete or poor ductwork.

Comparing Energy Efficiency

Energy efficiency must also be a consideration when looking at HVAC installation equipment. While you may reduce your upfront costs with a less efficient system, you will be paying more in the long run. Energy costs are on the rise and expected to continue to do so. With a low efficiency system, you could end up spending hundreds of dollars more a year on heating and cooling your home. More efficient systems can quickly pay for themselves by reducing your energy use. Studies show that systems produced today are up to 50 percent more energy efficient than those made just 10 years ago.

When looking at different HVAC systems, you can compare their efficiencies by looking at their seasonal energy efficiency (SEER) and annual fuel utilization efficiency (AFUE) ratings. These ratings are an industry standardized measurement for HVAC systems. SEER ratings measure the amount of energy required to produce conditioned air. Higher numbers indicate better efficiency. A SEER rating of 20 or higher is considered to be very efficient, and there are units available with ratings as high as 28.

AFUE ratings represent the energy efficiency of a heating system in percentages, and higher ratings also indicate higher efficiency. Systems that have AFUE ratings of 90 or higher are considered to be very efficient. Currently, there are furnaces available with ratings as high as 98.
