Aren't they going to stop making the gas that is used in my home air
Most home air conditioners use the refrigerant gas R-22 which is also referred to as
Freon-22. Since this refrigerant is made up of some ozone depleting chemicals, it will soon
be phased out. The timetable is as follows: 1996 - production cap set at 15 million
kilograms, 2004 - production cap reduced 35%, 2010 - Freon-22 equipment ban and a
65% reduction in production, 2015 - a further 90% reduction in the manufacture of
Freon-22, 2020 - Freon-22 production will be only 76 thousand kilograms 2030 - Freon-22
will no longer be made As you can guess, the cost of buying this refrigerant for your home
air conditioner is getting ready to skyrocket just like the Freon-12 produced for automobiles
and home appliances. Good news! Trane Co. is now producing equipment using an
environmentally friendly refrigerant gas called 410A. This new refrigerant is not only ozone
friendly but lends itself to natural high efficiency operation which makes it doubly good for
the planet. The Trane air conditioning systems have used 410A since 1996 and it is now
the industry standard. Please call us at 817-341-1248 for further details or go to
At what temperature should I set my thermostat?
The short answer is: whatever is comfortable to you. After all, the reason you have an air
conditioner or heater is to keep you comfortable. On the other hand, if you like your home
especially cool in summer or especially warm in winter, then your cost of operation will
certainly rise. Example: The "normal" setting for heating is 70 degrees F, if you set your
thermostat to 74 degrees, you heating bill will rise 22%. In summer, the "normal" setting is
78 degrees F, if you set your thermostat to 74 degrees, your air conditioning bill will rise
39%, and if you set it to 72 degrees, your bill will rise 63%. This may or may not be a big
deal, it depends on the size of your home, how well it is insulated, the efficiency of your
equipment, and how comfortable you want to be!
How often should I change or clean my air filter?
It depends, please read below: A. Disposable filters: replace every 60 days UNLESS you
have children, have pets, have more than two adults living in the home, or live in a dusty
area, then every 30 days. We don't mean to sound like smart alecs, but that is what
experience has shown! B. Pleated disposable filters: replace every 30 days regardless of
what the manufacturer says on the wrapping. In fact, although these filters work great, if they
are too small for the amount of air that your furnace or air conditioner needs, they can work
a little too well and may cause an air restriction in your system which will shorten it's life. 3.
Washable filters: a. Flexible "hoghair" (blue or green) filters: clean every 30 or 60 days -
replace when they start sagging or are torn. b. Metal supported foam filters: clean every 30
or 60 days - replace when torn. c. Plastic thick mesh filters, sometimes called electrostatic
or "allergy relief" filters: throw away as soon as possible! Independent testing has show
these filters to be no more effective than any of the cheaper filters mentioned above and
may cause a worse air-flow restriction than a pleated filter! d. Metal mesh filters: wash
every 30 or 60 days, don't forget to re-spray with a filter adhesive - replace when torn or so
bent it that it doesn't properly fit in it's track anymore. 4. Bryant or Carrier EZ Flex high
efficiency filters: replace every six months. 5. Spaceguard/Aprilaire filters: replace annually,
but you may want to check them after six months, just in case. 6. Electronic air cleaners:
wash the cells in the dishwasher monthly or more often if your allergies are driving you nuts!
What does SEER and AFUE mean?
Both of these abbreviations relate to the U.S. Department of Energy standards for air
conditioning and gas furnaces. SEER: Seasonal energy efficiency rating AFUE: Annual fuel
utilization efficiency In both cases, the higher the SEER or AFUE, the more efficient your
system will be. For example, the difference between a 10 SEER air conditioner and a 13
SEER system means that for the same amount of cooling, your unit will use 23% less
electricity! Wouldn't that be great?
How often should I have my central air conditioner or furnace serviced?
We recommend service in both the spring and fall every year. Many people know to timely
replace or clean their air filter(s) but only call for service when their equipment actually
breaks down. This says a lot about the reliability of their central heating and cooling system.
Compared to an automobile, a typical air conditioner in North Texas puts on more than
88,000 miles per year, heat pumps even more. However, the greatest majority of our night
and weekend calls are for persons who occasionally, or sometimes never have had their
unit serviced. Many of the more extensive repairs that we do make were actually caused by
smaller, quickly repaired problems that caused a major breakdown. Also many high utility
bills are the result of easily correctable inefficiencies in their systems.
What do they mean when they say I must purchase at least a 13 SEER
efficiency air conditioner?
The U.S. Department of Energy has mandated that all central air conditioning units
manufactured after January 23, 2006 must have a seasonal energy efficiency rating of at
least 13.0. You can still purchase equipment with a lower rating after that date, but why?
The cost to run central air conditioning over the life of the unit is much more that the initial
investment in the equipment itself.
