Larger Opportunities: Heating, Cooling & Ventilating

Proper heating, ventilating, and air-conditioning (known in the trade as HVAC) are key to maintaining a comfortable, and healthy environment. Improved heating and cooling performance along with substantial energy savings can be achieved by implementing energy-efficiency measures.

Whether you wish to improve the efficiency of your existing heating and cooling systems or are considering upgrading to a new system, the information on this page will help you to make informed decisions!

Cooling and Heating Load Reduction

One of the first steps you should consider in your congregational facility before upgrading your heating and cooling system is to reduce your load (i.e. how much heating and cooling you actually use). Reducing your facility's load allows existing systems to operate less frequently and newer systems to be designed smaller, thereby lowering operating costs. Common load reduction strategies include:

Once you have addressed these areas, you can then make the most of your heating and cooling equipment dollars.

Heating and Cooling Systems

FurnaceHeating and cooling systems are critical to most buildings, but also represent a large component of many facilities' utility expenses. Cooling systems, in particular, are typically very energy intensive and are almost always fueled by electricity. Their operation typically coincides with periods that are subject to peak and time of use charges.

Heating and cooling systems have advanced significantly in design and efficiency. For example, today's air conditioners use less energy to produce the same amount of cooling as older air conditioners. Even if your air conditioner is relatively new, you can still save on your cooling energy costs by replacing it with a more efficient model.

Heating and Cooling System Tips:

Project Suggestion

For commercial facilities, request an ACCA Manual N, and for home businesses request a Manual J, evaluation of your facility's heating and cooling loads before purchasing any major heating or cooling system. By following these guidelines you will receive a system that is sized appropriately for your facility.

Control Systems

Programmable Thermostat A great way to improve the efficiency of heating and cooling systems is to incorporate control strategies that ensure systems are used only when necessary. Common control strategies include programmable thermostats, multiple zones, and CO2 demand sensors. These strategies can be specified on new heating and cooling systems and retrofitted to older systems as well.

HVAC Success!

The Holy Trinity Lutheran Church in Berlin, PA recently replaced their 40 year old, large, inefficient heating system with three smaller efficient heating units. This allows them to turn on only what is needed at the time instead of firing up a large heating unit to heat small areas of the church or add just a little heat on those days when there is a slight chill in the air. They estimate that this will reduce their heating bill by as much as 50%.


Just like your automobile, your facility's heating and cooling systems need maintenance to operate efficiently. To improve efficiency and help ensure reliability and long life, consider the following tips.
