Heating and Cooling Q & A:
Q: How often do I need a tune-up?
A: To keep systems at their peak performance and to maintain any manufacturer's warranties that may exist; it is recommended that a tune-up be performed twice a year. Once for the cooling season and once for the heating season.
Q: Will a tune-up lower my utility bill?
A: It certainly can! There are many potential problems that can be detected before they turn into greater problems when performing a tune-up. Many of these issues are easily corrected, but if they go unnoticed, may leave a big surprise in the mail in the form of your electric bill.
Q: How often should I change my air filter?
A: An ordinary fiberglass filter should be changed monthly. A good reminder could be to change your Filter when you get your electric bill. Higher grade pleated filters may be changed every 2-3 months depending on how often the system runs. Q: What is carbon monoxide? A: Carbon monoxide is a dangerous gas that is the result of incomplete combustion and is often present when a furnace or gas water heater is improperly operating or improperly vented. Carbon monoxide is a colorless, odorless, tasteless gas which has been linked to many illnesses. To protect you and your family, Q: Is my system big enough for my home? A: In calculating what size system you should have, a "whole house heat load calculation" must be done. Just going by how many square feet the home is does not tell you how well a home is insulated or how quickly your home gains heat in the summer and loses heat in the winter. Sterling Services offers this service free of charge to help you make the right long term decision in choosing a new system. A: A refrigeration system is designed to be a totally enclosed "loop" in which the refrigerant is circulated over and over. Therefore, if refrigerant must be added, it likely has leaked out, resulting in extreme wear and tear, increased operating cost, as well as environmental concerns. Because of this, refrigerant leaks must be located and repaired when they are believed to exist.
Q: How often does my system need to be recharged with Freon?
Heating & Cooling Glossary of Terms:
- "Package Unit" - A complete self contained heating & cooling system, typically found in rooftop applications.
- "Split System" - Also a complete system, but separated into two sections; an outdoor section called a 'condenser' or 'condensing unit', and an indoor section consisting of a 'furnace/coil' combination or 'air handler'.
- "Freon" - A trade name for 'refrigerant' which is a broad term which does not specify refrigerant type.
R-22 is the type used in residential & light commercial
applications until present, at which time is being phased
out in favor of the more environmentally friendly R-410A.
When considering a new system, one with R-410A is highly
recommended, as supplies of R-22 is expected to decrease in
availability.
- "Heat Pump" - An air conditioning system which has the ability to reverse the flow of refrigerant and serve as both a cooling source and heating source without the need for any fuel source.
- "S.E.E.R." - Seasonal Energy Efficiency Ratio: The rating used in measuring how energy efficient an air conditioning system is. The higher the S.E.E.R. rating, the more efficient it is. Federal law now requires all units manufactured must meet or exceed 13 S.E.E.R., but are available up to about 20 S.E.E.R.
- "A.F.U.E." - Annual Fuel Utilization Efficiency: The rating used in measuring how efficient a fuel burning appliance is. The higher the A.F.U.E., the more fuel efficient it is. Federal law now requires all furnaces manufactured meet or exceed 80% A.F.U.E. and many are rated in the 90% or 95% range.
An older furnace may have been 60% efficient, meaning .60¢
if each dollar generates usable heat and the remaining .40¢ is wasted, only
to be vented out the flue pipe.
- "I.A.Q." - Indoor Air Quality: Such I.A.Q. products include air cleaners/purifiers, ventilators, humidifiers, air sampling devices and alarms that detect harmful levels of unwanted and dangerous gases.
