How to Increase HVAC Energy Efficiency

How do you Increase your HVAC energy efficiency?

Your HVAC systems represent a large energy expense. Some of that energy may be wasted if your systems are not running efficiently or if you are losing heat or air. There are things you can do to save energy and energy costs. The department of energy estimates that you can improve energy savings by as much as 35% by increasing your energy efficiency.

Insulate, Reduce Air Loss

To increase energy efficiency make sure you are not losing your conditioned air (heated or cooled) through doors, windows, attic. Adding insulation if there not enough can help keep your conditioned air where it belongs. Additionally, it can be beneficial to check exposed pipes, outlets and ductwork for air loss. Insulated wrap can be applied to these areas to properly seal them.

Your Air Flow

Replacing your Air Filters and keeping your indoor and outdoor unit(s) free of dirt and debris can help your air flow. This can help increase energy efficiency. Your systems require proper airflow in order to operate efficiently. Air filters should be checked every month and replaced at least every three months.

Programmable Thermostats

Installing Programmable Thermostats is a great way to reduce your energy costs. They enable you to heat or cool specific areas at specific times of the day. This can result in energy savings by reducing your energy use in those areas.

Upgrade Your Equipment

If your existing system is older, but well maintained it may benefit from an upgrade. Replacing components on otherwise well maintained systems may be a good option for you. Components such as compressors, controls or other parts are a less expensive replacement option to complete system replacement.

Invest in High Energy Rated Replacement HVAC Systems

HVAC Maintenance

Regular HVAC Maintenance is will increase energy efficiency. It is very important to keep your systems properly maintained. HVAC maintenance assures that your systems are performing properly and at their peak efficiency for maximum results. Air Doctor Heating and Air offers a maintenance contract which has us inspect your systems twice a year- heating in the fall and air conditioning in the spring. Our comprehensive inspection will ensure your systems are operating at their best.

A Calibrated Door Blower Test detects energy loss

Door Blower Test

The calibrated door blower test (air leakage test) allows an analysis of heat or cold air loss in a house. These leaks occur through doors, windows, vents or holes. Air leakage results in energy loss and higher energy costs. This test can detect even small leaks which could be costing quite a bit over time and make your HVAC systems work harder. A Door Blower Test measures ACH (Air changes per hour).

Manometer

The testing equipment consists of an exhaust fan mechanism with a sealed doorway block. These are mounted usually at the front door and depressurizes the interior of the house. When this happens the now greater outside air pressure tries to seep in through any opening regardless of how small. A manometer is used to measure air pressure once negative air pressure is achieved. A technician then goes room to room throughout the house to locate these seepages.

Properly Sealing your home

Once the areas of seepage are identified then a plan can be enacted to properly seal the home. An attic is a very common place to lose heat. Often testing begins there before proceeding to the main floor and the rest of the home. Fixes may include filling holes, adding or replacing insulation and seals for doors and windows.

IECC Energy Code

The IECC (International Energy Conservation Code) is a measure of a building’s thermal envelope (air tightness). These codes are energy conservation specific and are required in some new building codes for new construction. These codes are required in order to meet energy conservation requirements. In order to comply with these codes this testing becomes necessary.

The Calibrated Door Blower (Air Leakage) test can benefit everyday homeowners when they are trying to reduce their energy costs. Reducing energy costs are very beneficial, but limiting air loss can also help your HVAC systems work less. Air Doctor Heating and Air can help you assess your home’s need to have the test.

Multizone Heating and Cooling Benefits

Zones

Multizone heating and cooling systems can be a big benefit for many reasons. Comfort being one and energy savings the most substantial other. This type of system can involve:

  • Multiple units
  • Valves
  • Pumps
  • Thermostats
  • Other controls depending and the size and scope of the home and the needs which must be met.

Comfort

From a comfort standpoint, multizone systems make great sense. Whether there are few or many people residing in the home, all can benefit. Multizone systems can allow maximum control over temperatures in specified zones or regions in the home. Keep bedrooms cooler or at varying temperatures than the living areas for example or vice versa. Multizone systems can be tailored to fit your individual or family’s specific needs. Programmable smart thermostats can maximize your control over the temperatures in all areas of your home.

It can be very difficult or impossible to have even heat or cooling distribution if your home has multiple levels. Heat naturally rises and so can interfere with your heating and cooling comfort and lead to unnecessarily heating a lower area where heat is escaping.

Energy Savings

Lower temperature settings in zones less frequently used rooms. This can add up to substantial energy savings and far less energy waste. Properly zoned systems can save up to 30% off non- zoned systems.

Generally speaking multizone systems utilize more components than standard central systems. Over the long term there are bigger potential savings to the homeowner. A home can be zoned into two or more zones. Typically the zones or regions are established based on locale and similarly desired temperature settings for those areas. Many zoned systems also come with remote controlled thermostats for added convenience.
