Proper HVAC Fan Maintenance and Control can Save Energy Dollars
Fan Maintenance Energy Savings - According to the Department of Energy fans consume nearly 80 billion kilowatts of energy per year. Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users.
Assuming the design engineer selected the proper fan and proper installation in the well-designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)? To make a good evaluation you need to look at several different factors in fan operation.
Heat Pump Thermostats - To the average person a heat pump thermostat can be a very complicated thermostat compared to the typical thermostat which serves an air conditioning system with gas, electric, or an oil furnace. Of course, the heat pump thermostat typically has more wire terminations than the regular thermostat.
It has more switches to control emergency heat, and some even have lights, which will indicate that the auxiliary heat or emergency heat is functioning. Most heat pump thermostats are two-stage thermostats for the heating mode and a single stage for the cooling mode.
Heat Pump Electric Backup Heating Basics. There are different types of electric heating available in homes. Probably the most common use for electric heat other than portable electric heating units is electric heat strips. Electric heat strips used for backup heat in heat pumps. Sizing the electric heat strips for heat pump backup heating applications will depend on many different variables.
These variables include the size of the space to be heated and the insulation values of the whole structure. It also includes doors and windows. Additionally, it includes the geographical location of the dwelling, along with many other factors. Backup heat for heat pumps is essential for the defrost cycle. (more…)
Heat Pump Components - Heat Pumps are similar to air conditioners with a few extra components. Components added to allow the heat pump to offer both heating and cooling. The two major differences between a heat pump and an air conditioner are the controls and the refrigeration circuit.
While there are many different types of heat pumps and air conditioners the methods and means these two types of heating and cooling systems use are basically the same. (more…)
Boiler Combustion Efficiency | HVAC Heating Systems - It is important to understand that a commercial application (can also apply to residential boiler applications) is going to consume a large amount of the energy budget, therefore it is important to track efficiency ratings because a slight drop in the efficiency can cause a sharp increase in the energy costs.

Determine That You Actually Have a Standing Pilot Gas System
Check to Make Sure You Have Fuel
Understand the Valve Function
Light the Pilot Light
Enjoy the Warmth
How To Light a Pilot Light – Standing pilot gas furnaces and water heaters are still around today even in newer homes. All the major hardware stores and HVAC dealers carry standing pilot appliances. Although a new standing pilot gas furnace or boiler is rare finds these days. Because of the move to higher efficiency models and the wide use of electronic ignition technology which improves efficiency.
Before you proceed you’ll want to determine if you actually have a standing pilot system in your HVAC furnace, boiler, or water heater.
In many cases, on many appliances, there are basic instructions on lighting it, in fact, you do have a standing pilot system. Check around the main panel or look at the gas valve itself. Sometimes, especially on older appliances, there are no instructions on it if the pilot light goes out on a standing pilot gas furnace, boiler, or water heater.
The label or sticker on the furnace, boiler, or water heater faded a long time ago and you will need to follow the instructions in this article. (more…)
HVAC Tip - Air Conditioner & Heat Pump Tips: Additional Helpful Hints:
Always change your air filter on a monthly basis
Make sure all your supply vents are open and unobstructed
Keep area clean around indoor unit especially the return grills
Keep outdoor units free of leaves, grass, and debris including trash cans and/or children's toys or playthings like small plastic pools or playhouses.
Additionally your service technician will appreciate you not planting holly bushes near the outside unit
Lastly have system serviced every six months - once for heating and once for cooling before the season starts
