Frequently Asked Questions
1. Why does my system require refrigerant yearly?
If you require a refrigerant for your air conditioner or heat pump each year, it is likely that there is a leak in your system which could be in the line set, in the coil, or in the condenser itself. Typically, the amount of refrigerant that you lose will depend on the size of the leak.
2. How often should I have air conditioning serviced?
You unit should be inspected, serviced, and cleaned at least once a year, especially during the Spring season to ensure it operates at its peak energy efficiency and is ready to cool your house during the months you need it most. As your HVAC system runs, it accumulates dust and dirt in key areas that affect its efficiency such as the condensing coils and air filters. Left unchecked, your A/C system can lose 5% of its operating efficiency each year and prevent the cooling system in your home from operating at it's regular capability.
3. What is SEER?
The SEER measures the air conditioning and heat pump cooling efficiency. Air conditioning equipment is rated by the seasonal energy efficiency rating, or SEER. The higher the SEER rating, the more efficient the equipment is. Newer manufactured equipment now must meet a 13.0 SEER rating, with some manufacturers producing equipment at SEER's as high as 21.0.
4. How can I reduce energy cost?
The following tips can help keep your air conditioner running efficiently and prolong the life expectancy of the unit:
* Replace filters every 1-2 months during the cooling season. You can lower energy use by 5-15% by replacing a dirty, clogged filter with a clean one.
*Check the evaporator coil every year and clean it as needed.
*Clean the area around outdoor condenser coils by removing debris and trimming foliage, so there are at least 2 feet around the condenser for airflow. Be aware of debris build up from dryer vents, falling leaves, and trimming and mowing the lawn. Clean away the debris as needed throughout the cooling season.
* Are the fins on your evaporator or condenser coils bent? If so, they may be blocking airflow. Look for a "fin comb" from an AC wholesaler to get them bent back.
*Pass a stiff wire through the unit's drain channels. When they are clogged, the unit can't reduce humidity and excess moisture causing discoloration in the walls or carpet.
* For room or window air conditioner, inspect the seal between the air conditioner and the frame to ensure that the frame makes contact with the units’ metal case. Damage to the seal can cause leaks and waste energy.
* Read more about air conditioning maintenance and common air conditioner problems. For more than basic maintenance, be sure to contact a certified professional.
5. Should outdoor units be covered in the Winter?
It is not recommended as the outdoor condenser is built to withstand the environment and should not be covered. More often than not, air conditioners can be turned on by someone in your home without acknowledgement that the outdoor unit has been covered. This creates potential damage to your condenser and it's internal components.
6. If an outdoor unit requires replacement, should the indoor unit be replaced as well?
It is recommended that both the indoor and outdoor equipment are replaced together, especially with new EPA requirements to phase out R-22 refrigerant by 2020. Currently, there are other options to replace just one of the components without the other, with the price of inefficiency and high energy costs. That, however, is subject to change with the upgrades in the building codes and National Energy Codes being enforced gradually, state by state. The efficiency rating on a condenser is based on the entire system being replaced.
