1. Can I just replace the outdoor unit on an older system to save money?
Replacing only one of the units could reduce the system’s capacity and efficiency to cool a home by up to 40 percent. The two parts of a split system or heat pump system (the indoor and outdoor unit) are specifically designed to work together as a “team” to provide top performance and maximum efficiency. In essence, the system may not be able to keep up with the thermostat setting and run constantly resulting in higher electric bills because the system will have to work harder and run longer to keep the house cool.
2. What is a Heat Pump System?
A heat pump is an all-in-one heating and cooling system. It heats a home in the winter and then cools it in the summer. A typical heat pump installation consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner.
3. Will a bigger system perform better?
No. It is very important to properly size the system to the square footage of the home for cooling efficiency as wells as proper humidity control levels. Oversized equipment often runs for very short periods and often may not reach its steady-state or “cruising speed” where it operates most efficiently. Over-sizing by 50% has been shown to increase energy cost by 9%.
4. How often should I change my air filter?
You should change your filters every month. Operating your system with dirty filters causes air restrictions, in turn wasting energy, due to the system having to work harder to warm or cool your home. A clean filter will also prevent dust and dirt from building up in the system which could lead to expensive repairs and/or early system failure.
5. Should I have my furnace and air conditioner serviced every year?
Yes, keeping your heating and cooling systems in good working order means your utility bills will be lower and you’ll need repairs less often.
6. What are the benefits of a programmable thermostat?
A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.
7. Why should I seal my heating and cooling ducts?
Ducts that move air to and from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20%, and sometimes much more.
8. How can I reduce allergens and improve the air quality in my home?
A well–maintained and efficient air cleaner can significantly lower the amount of allergens and pollutants from the air in your home.
9. What does an air cleaner do?
An air cleaner will filter out the particles in the air that cause irritation, such as pollen, dust and other contaminates. However, in order for any air cleaner to work correctly, the particles need to pass through it. If the particles are not in the air system (for example, dust on the furniture) an air cleaner will not remove them.
10. What is SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio. It’s a number that describes how well air-conditioning equipment works. A higher SEER rating means better efficiency and lower energy bills.
SEER stands for Season Energy Efficiency Ratio and applies to central air conditioners and heat pumps. The minimum set by the Department of Energy is 13 SEER and for Energy Star, 14 SEER. The higher the SEER, the greater the energy economy.
11. Why is my HVAC system freezing up?
There are several things that can cause your HVAC system to freeze up. A dirty filter can cause an airflow restriction, which can cause it to freeze up. In some cases, freezing up is caused by a leak in the refrigerant lines. Another reason could be a dirty evaporator coil. Over time, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter, causing an airflow restriction. Having a defective blower motor or relay is another cause. A blower motor not running at the proper speed or not running at all can cause freezing. It can also be intermittent, starting at full speed and slowing down after it heats up. A relay could cause it to start one time and not the next.
