Electric heat pumps and gas furnaces are the most common forms of heating systems. While these systems offer fantastic efficiency, in order to maintain this standard and keep your utility bills under control, you should follow these three tips.
Regularly Change the Filters:
Most manufacturers and HVAC specialists will often speak about changing filters, and the reason for this is that it is very important. Even though filters appear to only be a minor component, they are vital for correct and efficient operation. If the filters become clogged with dust, lint and other debris, it will restrict airflow and cause a number of issues including forcing the unit to work harder. Fortunately, changing filters is a relatively easy and inexpensive task. Most manufacturers recommend that filters are replaced every four to six weeks during heavy use, but if you have any pets or smokers in your household, you may need to change them more frequently.
The precise instructions for changing the filters on your heat pump or furnace will be listed in your owner’s manual. The manual will also detail if your system is equipped with a safety sensor that can shut off the unit if airflow is compromised. This is designed to prevent a catastrophic failure and highlights the importance of ensuring your filters are changed regularly.
Keep Your Room Vents Clear:
The vents or air registers in your rooms deliver the air heated by your heat pump or furnace. In order for the system to “breathe” and prevent additional stress, these vents need to be kept unobstructed. This will allow your rooms to efficiently warm up and optimize “static pressure.” Static pressure is the term used to describe how easily the air can flow and this is vital for correct HVAC operation. Most manufacturers state that the static pressure should not exceed a particular level to ensure that the system maintains efficiency and effectiveness.
You should keep furniture, holiday decorations and any other items have moved and accidentally block the vents. You should also avoid closing off your vents by shutting off the dampers behind each grill. Many homeowners assume that shutting off the vent can save energy, but in fact, it increases pressure within the system and can potentially cause damage.
Seal Your Air Ducts:
Even small holes or gaps in your ductwork can significantly compromise your system efficiency. These holes tend to form where two ducts are connected or where they join the unit. Although one small hole is not a major problem, it is usually an indication of a declining situation, which could lead to a larger hole developing. Improperly sealed ducts allow air to escape, wasting energy. Additionally, if the holes are in the return ducts, it could allow dirty air from the attic to be drawn into the system and compromise your indoor air quality. While there are some DIY materials for sealing ducts, don’t be tempting to cut corners. It is worth having a professional HVAC specialist check your ducts for leaks and ensure that they are properly sealed.
